For large-scale industrial plants, the quality of concrete floor construction directly affects the normal production. Therefore, the floors of industrial plants now generally require special bearing capacity, anti-slip wear resistance, and flatness. Through practical research, we found that in the construction of steel fiber concrete wear-resistant ground in industrial plants, using a wider range of concrete laser leveling/ leveling machines for leveling, coupled with driving double-disc trowels for ground finishing, can Greatly improve the construction quality and speed of the floor. The following briefly introduces the characteristics, principles, processes and benefits of the construction of the concrete laser leveling/ leveling machine + car troweling machine.
◤Construction method characteristics◥:
◆Higher construction quality: The floor elevation can reach laser-level precision, and the ground flatness and levelness are more than three times that of traditional manual leveling operations, which can guarantee the owner's requirements for ground flatness and levelness.
◆Faster construction speed: It can greatly shorten the construction period and improve the work efficiency by 100~300% (150~300 square meters of paving work can be completed per hour, and 1500~2500 square meters can be completed every day on average), and the manpower can be reduced by more than 30%. It is especially suitable for engineering projects that require tight construction schedules, large injection areas, and high quality requirements.
◆Better integrity of the ground: It is very easy to achieve large-area overall paving. This paving technology can avoid the hollowing problem caused by layered pouring of the floor. On the other hand, it can reduce a large number of construction joints and make the overall floor Sex is better.
◆The post-maintenance cost of the ground is greatly reduced: due to the large-area overall paving, the construction joints can be reduced by 3-5 times, and the construction joints are easily damaged by the load, which can greatly reduce the post-maintenance cost of the ground.
◆Wide scope of application: Not only can it be constructed on reinforced concrete ground with single-layer or double-layer steel mesh. Among them, the light-duty laser leveling machine is suitable for all kinds of concrete floors and reinforced concrete floors with single or double-layer steel mesh, especially suitable for large-scale, high-quality ground construction.
◤Process Principle◥:
◆Concrete laser leveling machine leveling principle: use precision laser technology, closed-loop control technology and highly precise hydraulic system to achieve leveling under the automatic control of the computer. This closed-loop control can adapt to the elevation of the concrete surface and can Automatic adjustment 6 times.
◆Concrete laser leveling machine leveling principle: Rely on the hydraulically driven leveling head, cooperate with the laser system and computer control system to complete the leveling work while automatically leveling. The leveling head is equipped with a scraper with integrated design and a leveling beam with a vibrator, which integrates all leveling work into one body. The computer control system automatically adjusts the elevation 6 times per second in real time, and the vibration frequency of the vibrator with balanced design can reach 30005000 times per minute.
◆Principle of driving-type troweling machine finishing: the driving-type troweling machine is equipped with a double-disk knife holder, and the hydraulic drive system provides power and torque for the two non-overlapping knife holders respectively. To achieve better results, use the joystick on the handle to control the sprinkler system, so that the dry ground can be sprinkled at any time for remediation.

Compared with the original concrete floor construction technology, the benefits of using the dual-machine operation of concrete laser leveling machine + driving trowel machine are: fast construction speed, low construction investment, good overall appearance of the ground, and large investment in ground construction joints and corresponding materials. reduce and so on. In the future, with the continuous improvement of construction quality requirements for building ground engineering, this construction method will be widely promoted and applied.
