  At the moment when the construction field is constantly innovating, the pursuit of flatness, strength and construction efficiency in large-area floor construction has reached a new height. Traditional construction methods are difficult to accurately control flatness when dealing with large-scale ground operations, and the construction period is long. The use of concrete laser leveling machine Beton – Laser – Nivelliermaschine to implement one-time forming construction has become an effective solution to break through these bottlenecks and provide strong guarantees for creating high-quality ultra-flat wear-resistant floors. Excellent precision: With the help of advanced laser systems, Macchina livellatrice laser per calcestruzzo has extremely high control accuracy for ground elevation, and can control flatness deviation within a very small range, far exceeding traditional construction methods, and meeting the stringent requirements of high-standard ultra-flat floors. Efficient operation: The equipment has a leading degree of automation, and a large area of ​​ground leveling can be completed in a single operation. Compared with traditional manual leveling, the construction period is greatly shortened and the construction efficiency is greatly improved. Material optimization: With precise elevation control, it can effectively avoid the situation of too much or too little concrete laying, reduce material waste and construction costs. Performance enhancement: Uniform vibration during the leveling process makes the internal structure of the concrete more compact and uniform, significantly enhances the strength and wear resistance of the ground, and extends the service life of the ground. This method is widely used in various large-area places with high requirements for ground flatness and wear resistance, such as industrial plants that need to withstand the operation of heavy equipment; logistics warehouses, where frequent cargo handling causes great damage to the ground; large shopping malls, where there is a large flow of people and the ground needs to be beautiful; parking lots, where vehicles frequently enter and exit and test the durability of the ground, etc. The core of Extendedoras de hormigón lies in the collaborative work of high-precision laser transmitters and receivers. The laser transmitter emits a stable horizontal laser beam, just like building a precise reference plane in the air. The laser receiver is installed on the leveling machine frame to capture the laser signal in real time and quickly transmit it to the control system. The control system automatically and accurately adjusts the height of the screed blade according to the received signal to ensure accurate leveling of the concrete surface during the process. At the same time, the vibrating device equipped with the screed works synchronously to fully vibrate the concrete, ensure its density, and lay the foundation for high-quality ground. Base treatment → measurement and layout → installation of formwork → concrete pouring → laser leveling machine leveling → surface treatment (smoothing, spreading wear-resistant materials, etc.) → maintenance Base treatment Thoroughly remove debris, dust, oil and other pollutants on the surface of the base to ensure that the surface of the base is clean and flat, providing a good foundation for subsequent construction. Use compaction machinery to compact the base. For weak foundations, effective measures such as replacement and reinforcement piles are required to improve the bearing capacity of the base and prevent later ground settlement. Measurement and layout Use precision measuring instruments such as total stations to accurately measure and lay out the elevation control lines and construction boundaries of the floor according to the requirements of the design drawings. Set firm control points at a certain distance (usually 3-5 meters) on the base. These control points serve as key references for the initial positioning and calibration of the laser leveling machine to ensure the accuracy of the equipment's running trajectory and elevation control. Install the formwork Install the formwork strictly according to the measured layout position. The formwork should be made of materials with high strength and good rigidity, such as high-quality steel formwork or reinforced wooden formwork. Use a level to accurately adjust the elevation of the top surface of the formwork so that it is completely consistent with the design elevation. The joints of the formwork should be tight, and sealing strips or tapes can be used to seal to prevent leakage during concrete pouring and affect the quality of the ground. Preferably use commercial concrete, and its mix ratio needs to be professionally optimized according to factors such as engineering design strength, durability, and construction environment to ensure that the concrete performance meets the construction requirements. Concrete is efficiently transported to the construction area through equipment such as concrete pump trucks or mixer trucks. Pour in layers and sections from one end to the other. The pouring thickness should be 2-3 cm higher than the design elevation, and space for leveling should be reserved. During the pouring process, use an inserted vibrator or a flat vibrator to vibrate the concrete in time. The vibration points should be evenly distributed to avoid leakage or over-vibration and ensure the density of the concrete. Laser leveling machine leveling After the concrete pouring is completed, the laser leveling machine should be driven into the construction area as soon as possible to avoid the initial setting of the concrete affecting the leveling effect. Start the laser transmitter and laser leveling machine in turn, calibrate and debug the equipment comprehensively, and check whether the laser signal reception, scraper lifting control, and vibration device operation are normal. The operator sets a reasonable leveling machine route and speed according to the shape and area of ​​the construction site. The general speed is controlled at 1-3 meters per minute. During the leveling machine's movement, pay close attention to the equipment's operating status and the concrete surface. If local unevenness, depressions or convexities are found, stop the machine immediately and use manual filling or shoveling to repair. Surface treatment For ordinary floors, use a trowel machine for mechanical troweling after the initial setting of the concrete and before the final setting. The trowel machine operates in a horizontal and vertical cross-pattern, and generally needs to be troweled 3-5 times until the ground surface is flat, smooth, and free of smear marks. For wear-resistant floors, when the concrete is initially set, the wear-resistant materials (such as metal aggregates and non-metallic aggregate wear-resistant materials) selected according to the design requirements will be evenly spread on the concrete surface, and the spreading amount will be determined according to the material description and design requirements. After spreading, use a trowel to smooth the surface so that the wear-resistant materials and concrete are fully integrated to form a solid and wear-resistant floor surface. Maintenance After the ground construction is completed, maintenance work should be carried out immediately. Sprinkling maintenance can be used. The number of sprinkling times per day is determined according to the temperature and humidity, generally not less than 3-5 times, to keep the ground moist; plastic film can also be covered to prevent water evaporation and maintain the internal humidity of the concrete; curing agent can also be sprayed to form a protective film on the ground to achieve the maintenance effect. The curing time is usually not less than 7-14 days, and the specific duration is determined according to the concrete strength growth and relevant specifications. During the maintenance period, it is strictly forbidden for people and vehicles to walk or roll on the ground to prevent damage to the ground strength growth process and ensure that the final strength of the ground meets the design requirements. Concrete: must strictly meet the design strength grade requirements, have good workability, fluidity and durability, and ensure easy pouring and vibration during construction. Wear-resistant materials: accurately select wear-resistant materials according to the actual needs of the project and design standards. Metal aggregate wear-resistant materials have the characteristics of high hardness and high strength; non-metal aggregate wear-resistant materials have excellent performance in impact resistance and anti-static, and can be selected as needed. Formwork materials: steel formwork has the advantages of high strength and high turnover; wooden formwork has certain advantages in shape adaptability and splicing flexibility. Appropriate formwork materials can be selected according to construction conditions and cost considerations, but their strength and rigidity must meet construction requirements. Extendedoras de hormigón: According to the size of the construction site, the complexity of the shape and the ground design requirements, reasonably select equipment models with power, leveling width and accuracy. Laser transmitter and receiver: Closely matched with laser leveling machine, laser transmitter emits stable and accurate laser beam, receiver accurately captures signal, the two work together to ensure high precision of elevation control, and their performance directly affects the quality of ground leveling. Concrete delivery equipment: Concrete pump truck has strong mobility and is suitable for concrete delivery in different site conditions; mixer truck can ensure the uniformity and working performance of concrete during transportation, and can be reasonably used according to the construction site conditions. Trowel machine: Divided into hand-held type and driving type, selected according to the ground area and construction efficiency requirements. Its high-speed rotating trowel compacts and smoothes the ground to make the ground flat and smooth. Measuring instruments: Total station is used for large-area high-precision measurement and layout; level can accurately measure elevation; theodolite assists in determining angles and verticality. These measuring instruments jointly provide accurate data support for positioning and elevation control during construction. Quality management system construction: Set up a professional quality management team to clarify the specific responsibilities of each member in the stages of construction preparation, construction process and quality acceptance. Formulate a detailed quality management system and set clear and quantifiable quality goals, such as controlling the ground flatness deviation within ±2 mm. Raw material quality control: Each batch of raw materials such as concrete and wear-resistant materials entering the site shall be inspected and tested strictly in accordance with relevant standards. Concrete needs to be tested for slump, compressive strength and other indicators; wear-resistant materials need to be tested for their wear resistance, hardness and other properties to ensure that the quality of raw materials fully meets the design and specification requirements and ensure the quality of the project from the source. Construction process quality supervision: Arrange professional quality management personnel to supervise the entire construction process and strictly follow the established construction process and operation points. Focus on monitoring whether the laser operation is standardized, including equipment calibration, travel speed and route control; whether the concrete pouring and vibration meet the requirements, such as pouring sequence, vibration time and depth, etc.; the timing of polishing in the surface treatment process, the uniformity of wear-resistant material spreading, etc., and timely rectification when problems are found. Quality acceptance: After the construction is completed, the ground is comprehensively inspected in accordance with the current relevant national specifications and standards. Use professional measuring tools to detect the flatness and elevation deviation of the ground; use equipment such as rebound testers to detect the ground strength; and use wear resistance testers to test the wear resistance of wear-resistant floors. Only after all indicators meet the requirements after testing can the project quality be determined to be qualified. Building a safety management system: Develop a complete safety management system covering all aspects such as construction site safety protection, equipment operation specifications, and personnel safety training. Clarify the safety responsibilities of personnel in various positions, and implement safety responsibilities at all levels from project managers to front-line construction personnel. Safety education and training: Regularly organize construction personnel to participate in safety education and training, including safety regulations, safety operating procedures, accident case analysis, etc. New employees must undergo three-level safety education and training and pass the assessment before they can take up their posts. Special types of work (such as electricians, welders, machine operators, etc.) must be certified to work, and continuously improve the safety awareness and operating skills of construction personnel. Safety protection at the construction site: Set up obvious safety warning signs at the entrance of the construction site and dangerous areas (such as deep foundation pits, high-altitude working areas, etc.). Set up protective railings and safety nets for high-altitude working surfaces; equip construction workers with qualified personal protective equipment such as safety helmets, safety belts, safety shoes, and supervise their correct wearing and use. Equipment safety management: Establish a regular inspection and maintenance system for construction equipment such as laser levelers and concrete conveying equipment, conduct equipment appearance inspections and performance tests before and after each use, and conduct regular comprehensive maintenance and repairs. During the operation of the equipment, operators must strictly abide by the operating procedures, and illegal operations are strictly prohibited to prevent safety accidents caused by equipment failures or improper operations. Construction dust control: Harden the main roads in the construction site, and arrange special personnel to sprinkle water to reduce dust regularly. Sand, stone and other materials that are prone to dust are stored in closed silos, or covered with dustproof nets to reduce dust pollution. Construction noise control: Plan construction time reasonably to avoid high-noise operations during residents' rest time (such as 22:00 to 6:00 the next day). Take noise reduction measures for high-noise equipment such as concrete pumps and vibrators, such as installing silencers and setting up soundproof covers, to reduce the impact of construction noise on the surrounding environment. Waste treatment: Set up classified trash cans and waste storage sites at the construction site to classify and collect construction waste and domestic waste generated during the construction process. Recyclable waste (such as scrap steel, waste wood, etc.) is recycled and reused; non-recyclable waste is transported to designated locations for proper disposal in accordance with the requirements of local environmental protection departments to prevent environmental pollution.   Economic benefits: The one-time forming construction method of the laser leveling machine has greatly improved construction efficiency, shortened the construction period, and correspondingly reduced labor costs and equipment rental costs. Accurate leveling effectively reduces concrete waste and saves material costs. Comprehensive calculations can significantly improve the economic benefits of the project. Social benefits: The high-quality, ultra-flat, wear-resistant floor created by this method can effectively improve the performance and durability of the building, reduce the cost of later maintenance and renovation, provide the society with better building space, and create good social benefits. Environmental benefits: By implementing a series of environmental protection measures, such as dust control, noise control, and reasonable disposal of waste, the pollution of the surrounding environment during the construction process is reduced, which conforms to the concept of green environmental protection and sustainable development, and produces positive environmental benefits.  

  The laser leveling machine uses laser to level the ground, which is more accurate and has smaller ground errors after paving. Moreover, the construction of this equipment is very efficient, which is basically more than 3 times that of manual labor, and one device can do it, saving labor input and reducing capital cost investment. Definition of laser leveling machine: A laser-guided device for leveling and leveling fresh concrete. A concrete construction method that uses a laser leveling machine to spread and level the newly poured concrete. The laser leveling machine can significantly improve the flatness of the ground by leveling the ground. The ground constructed by the laser leveling machine and the traditional method is tested at 22 points (one point every 5mx4m), and the average flatness is 1.3mm and 4.1mm respectively. The leveling quality of laser leveling machines and other equipment is more than 3 times higher than that of traditional methods. The application of laser leveling machines and other equipment can realize large-scale construction, reduce a large number of construction joints, reduce the slump of concrete, and ensure the strength of concrete, so that the ground has good integrity and is not prone to cracks. Using laser leveling machines and other equipment to construct large concrete slabs can improve work efficiency by 3 times and save 30% compared with the traditional beam vibrator method. The construction area per hour is more than 300 square meters, and the workload can be completed every day at more than 3,000 square meters to 5,000 square meters, which greatly improves the work efficiency. Of course, high-quality and efficient large-area integral floor construction requires not only high-quality and reliable laser leveling machines, but also a fast and convenient spreader. Wanshi SL18-6 spreader equipment eliminates a series of defects such as uneven spreading, dust pollution, footprints, color difference, etc. caused by traditional wear-resistant aggregate spreading that affect the final beauty and quality of the floor, and truly realizes high-efficiency one-time mechanized spreading of wear-resistant aggregates. ● Integrated leveling head: It is composed of scrapers, vibrators, vibration plates, stirring cages and other components, which integrates multiple processes such as mixing, leveling, vibrating, and vibrating together, and is completed by the machine at one time. Improve efficiency and save labor. ● The high-frequency vibrator vibrates 4000 times per minute, and the vibrating plate of the leveling head vibrates evenly at high frequencies, making the concrete floor dense and avoiding cracking caused by stress concentration caused by deformation. It can effectively solve the problems of hollowing, peeling, cracking, and inequality on the ground. ● The leveling head can maintain the horizontal plane of construction under the dual transformation of the ups and downs of the foundation and the inclination of the ground. ● The laser measurement and control system automatically controls the elevation: The design elevation of the top surface of the floor is automatically controlled by the laser machine computer, which can ensure a very high ground flatness and can directly achieve precise leveling on the concrete layer. The ground flatness is not affected by the vibration of the construction template, and there is no need to support the template in the middle, which reduces the input of labor and materials, reduces the construction procedures, and speeds up the construction progress. Finally, it should be noted that if you want to use a concrete laser leveling machine, you must choose a professional concrete laser leveling machine brand equipment and pay attention to the use method. Without professional training, it may lead to inability to keep up with the construction efficiency and the effect will be greatly reduced.

  The concrete laser leveling machine is a device that uses the laser emitted by the transmitter as the reference plane, and controls the leveling head in real time through the laser receiver on the laser leveling machine, thereby achieving high-precision and rapid leveling of concrete. In large-area floor construction, its application is as follows: – High-precision leveling: The ground elevation is controlled by a laser system consisting of a laser transmitter, a laser receiver and a leveling rod. The laser transmitter emits lasers at a frequency of 10 times or even higher per second to form a control plane. The laser receiver on the laser leveling machine monitors the leveling head elevation in real time. The computer control system automatically adjusts the leveling head height according to the deviation to ensure the flatness and levelness of large-area floors. The accuracy can reach millimeter level (within ±3mm). Compared with traditional methods, the flatness and levelness are improved by more than 3 times. – High construction efficiency: Mechanized construction replaces a large number of manual labor, and the work efficiency is more than 3-5 times that of manual labor. For example, laser screed construction can adopt large-area compartments, with each compartment area up to 2,000 square meters, reducing the setting of construction joints, while reducing the work of force transmission rods and formwork support, speeding up the construction progress. Some large telescopic arm laser screeds can complete the leveling of 15 square meters of concrete each time, and some equipment can spread up to 5,000 square meters per day. – Improve ground quality: The powerful vibrator can vibrate at a frequency of up to 4,000 times/minute, which can ensure that the concrete is vibrated and compacted, making the entire paved concrete matrix homogeneous and dense, and the density and strength are more than 20% higher than traditional methods, effectively enhancing the wear resistance and impact resistance of the ground. – Save labor costs: The use of concrete laser screeds can save about 35% of labor, and some robot equipment can be remotely controlled by one person, which reduces manpower input while also reducing the labor intensity of workers. – Flexible adaptation to various working conditions: It can automatically control the longitudinal and transverse slopes, and can also be equipped with a three-dimensional special-shaped ground processing system to meet the construction of complex-shaped ground with high requirements such as drainage, such as squares with special drainage designs, airport runways and other places. – Industrial Plant: The third phase of the Flanders Plant is an industrial plant for manufacturing transmission parts assembly and testing. The steel fiber concrete metal wear-resistant floor area is 22,000 square meters and the floor thickness is 300 mm. It has high requirements for flatness and bearing capacity. The floor flatness error is required to be controlled within 3 mm. The use of laser leveling machine construction meets high standards. – Underground Garage: The underground garage of the National Treasury Unified Payment Center in Xicheng District, Beijing has an area of ​​10,500 square meters of metal wear-resistant floor and a floor thickness of 200 mm. The use of this equipment has achieved good results; in the construction of the basement concrete floor of a company's production headquarters project in Suzhou, the four-wheel laser floor leveling robot solved the construction problems of large volume, tight schedule, and high strength, and the flatness deviation was controlled within 5 mm. – New Energy Vehicle Intelligent Industrial Park: In order to ensure the safety of AGV transport vehicles, the Feixi New Energy Vehicle Intelligent Industrial Park EPC project has strict requirements on floor quality. The steel fiber concrete leveling process of this project uses a large laser leveling machine, which greatly improves the flatness of the ground. – Equipment Debugging and Maintenance: Before construction, the laser transmitter, receiver and other equipment must be accurately installed and debugged to ensure that their position is accurate and they operate normally; during the construction process, the equipment must be regularly inspected and maintained to avoid equipment failures affecting the construction quality and progress. – Construction Site and Environment: The construction site should be cleared of obstacles in advance to ensure that the laser signal is not blocked; at the same time, the impact of environmental factors such as temperature and wind on the construction should be considered, and corresponding measures should be taken to deal with it, such as paying attention to the concrete setting speed at high temperatures and avoiding the shaking of the laser transmitter in windy weather. – Concrete Quality Control: Strictly control the mix ratio, slump, initial setting time and other parameters of the concrete to ensure that the quality of the concrete is uniform and stable, so as to ensure the construction effect of the laser leveling machine. – Personnel operating skills: Operators must undergo professional training, be familiar with the operating procedures and techniques of the equipment, and be able to skillfully deal with various construction situations to ensure smooth construction.
