1. Main technical content
Large-area floor laser leveling machine application technology is an emerging concrete floor construction technology. It uses laser leveling machine as the main equipment, coupled with slurry lifter, automatic polishing machine and manual auxiliary leveling and polishing. The method of leveling and polishing the concrete surface has begun to be widely used in various large-area super-flat floor construction in my country.
This technology uses precision laser technology, closed-loop control technology and a highly precise hydraulic system to achieve level control under automatic computer control. Relying on the hydraulically driven leveling head, combined with the laser system and the computer control system, the leveling work is completed while automatically leveling. The computer control system automatically adjusts the elevation 5 times/s in real time to achieve flatness control, and exerts the vibrating function while leveling. The leveling head of the laser leveling machine is equipped with an integrated scraper, vibrator and leveling beam. The vibration frequency of the vibrator reaches 3000 times/min. It integrates leveling and vibrating work and completes it in one go. Greatly improve the uniformity and compactness of concrete and enhance the surface hardness of concrete. Achieve technical quality requirements and project progress requirements that traditional construction methods cannot achieve.
2.Technical indicators
The laser leveling machine is mainly composed of two parts: the leveling head and the body. The leveling head is responsible for leveling concrete projects and consists of scrapers, vibrators, leveling beams, laser receivers, cloth spirals and other components. At the same time, it is also equipped with laser transmitters, receivers and other accessories.
3. Analysis of economic and environmental effects
(1) One-time molding. The traditional leveling process requires secondary operations on the concrete project, and some parts need to be reworked. However, the laser leveling machine can achieve one-time molding, integrating multiple processes such as mixing, leveling, vibrating, and vibrating into one machine. Complete, improving efficiency and eliminating the need for patching operations. Suitable for dry hard concrete, fiber concrete and large aggregate concrete, the concrete density can be increased by more than 20%.
(2) Mechanized construction reduces labor requirements. The application technology of large-area floor laser leveling machines adopts mechanized operations to reduce work intensity and improve work efficiency. The leveling construction efficiency is 4-5 times that of traditional leveling operations.
(3) High leveling accuracy. The application technology of large-area floor laser leveling machine achieves excellent floor construction in one go (ground level ≤15mm, 3m inspection with ruler, flatness allowable deviation 3mm, flatness allowable deviation within the overlap range of 1.5m ≤3mm), exceeding The flat floor has a pure color and a good look and feel. Improve the company's construction level and market competitiveness in the field of large-area floor construction. Achieve good social benefits.
4. Scope of application
(1) Floors of electronics, microelectronics, communication products, computer production industries, and large precision instrument factories that require a high degree of cleanliness, beauty, dust-free, sterility, and anti-static.
(2) Warehouse, workshop, and garage floors are required to be wear-resistant, heavy-pressure resistant, impact-resistant, and chemical-resistant.
(3) Suitable for large-area factories, warehouses, logistics centers, airports, buildings and floors with high flatness requirements.
