Concrete laser leveling machine winter maintenance tips

Main Construction Process: Civil engineering formwork support (bottom formwork)→rebar tying→concrete pouring and laser leveling device elevation control→"VANSE" laser leveling machine for concrete leveling→professional technicians use a 3-meter scraper for precise leveling→single-disc troweling Machine pulping and smoothing→Professionals use a 3-meter scraper for precise leveling→Professional operation of double-disc driving troweling machine→Surface finishing→Product protection. 1. Civil engineering formwork (bottom formwork): Civil engineering formwork support (bottom formwork) is strictly controlled in elevation as in normal drawing design and construction specification acceptance standards, and the scaffolding is firmly supported. It should be noted that the "clear water concrete" building (ground) Surface and concrete pouring shall be constructed at the same time. In order to facilitate mechanical construction, there shall be no formwork or supporting elements higher than the building (ground) level, except for the reserved and pre-embedded levels. 2. Reinforcement tie-up: Because the surface layer is a building (ground) surface formed at one time by using the protective layer of reinforced concrete, the reinforcement must ensure that the concrete protective layer is sufficient, and the reinforcement, stirrup or weldment is not allowed to be placed in the wrong place. The concrete pouring surface layer is exposed, causing the machine to hit the steel bar, which not only destroys the machine but also destroys the surface layer of the building (ground). 3. Laser leveling instrument controls concrete pouring: set the elevation on the column reinforcement before concrete pouring, and lead the accurate elevation to the laser leveling instrument control system, and the concrete pouring personnel will control the elevation to be 5 times higher than the design elevation when scraping – Within the range of 10mm, lay a solid foundation for the leveling of the next laser leveling machine. 4. "VANSE" laser leveling machine leveling: In the case of accurate elevation setting by professional technicians, mechanical operators will precisely level the concrete surface under the control of the laser leveling instrument, and the leveling machine will automatically to calibrate and control the leveling machine to ensure the accuracy of leveling. 5. Leveling by professionals: This process is to re-measure the puddles with a laser sweeper when the bleeding of the concrete pouring surface is completed, fill the puddles with concrete, and use a 3-meter scraper to level the surface layer with a 360° rotation. To fully control the flatness and smooth the edge details of the column root formwork, use a laser sweeper to repeatedly detect until the requirements are met. 6. Single-disk troweling machine for smoothing and lifting slurry: while the concrete is poured in an orderly manner according to the specifications, the concrete poured earlier will reach the initial setting earlier by using the time difference of the concrete construction. 2-3mm footprint), it is convenient to use the "VANSE" single-disc troweling machine and troweling disc to carry out cross-breaking troweling to ensure the smooth control of the mechanical operation process.

  – Using the laser system for positioning and control, the horizontality and elevation control of the concrete surface can be accurately achieved, and the error can be controlled within ±3 mm, which is much higher than the accuracy of traditional manual leveling. – The laser signal has a wide coverage range, which can ensure the consistency of flatness in a large construction area and avoid local unevenness. – Mechanized operation replaces manual work, which can quickly complete the paving, leveling and vibration of concrete, and can process hundreds of square meters per hour, which is 3-5 times more efficient than traditional methods. – The equipment is relatively easy to operate, and only a few operators are needed to complete the entire construction process, reducing labor costs and management difficulties. – High-precision leveling can reduce the waste of concrete and avoid excessive use of materials or rework and repair due to inaccurate leveling. – Although the equipment purchase cost is high, in the long run, efficient construction progress and reduced labor costs can reduce the overall construction cost. – Vibration is carried out simultaneously during the leveling process to make the concrete density uniform, reduce quality problems such as hollowing and cracks, and improve the bearing capacity and durability of the ground. – The flat surface provides a good foundation for subsequent decoration projects (such as laying floor tiles, epoxy flooring, etc.), reducing the difficulty and cost of subsequent construction. – It can be used in large-scale concrete construction scenes such as large factories, warehouses, parking lots, airport runways, squares, etc., especially suitable for projects with high flatness requirements. – It can adapt to concrete pouring of different thicknesses, from thin cushion layers to thick foundations. – The purchase price of a laser leveling machine usually ranges from hundreds of thousands to millions of yuan. For small construction companies or short-term projects, the initial investment pressure is relatively large. – The equipment needs regular maintenance and upkeep. For example, the maintenance costs of components such as laser transmitters and hydraulic systems are relatively high. – Before construction, it is necessary to ensure that there is no strong electromagnetic interference around the site to avoid affecting the reception and transmission of laser signals. – For areas with complex terrain or obstacles (such as special-shaped structures and narrow spaces), the operation of the equipment will be restricted, and manual assistance may be required to complete local construction. – The debugging and operation of the equipment requires professionals. If the operator is not familiar with the laser system and equipment performance, it may affect the construction accuracy and efficiency. – Once the equipment fails or the laser system fails, professional technicians are required to repair it, which may cause construction interruption. – The equipment is large in size and heavy in weight. Special vehicles are required for transportation, the transfer cost is high, and a certain amount of space is required when moving within the site. – The equipment needs to consume diesel or electricity when running, which consumes a lot of energy. At the same time, the engine and hydraulic system will produce a lot of noise, which may be restricted when working in residential areas or noise-sensitive areas. Concrete laser leveling machines are widely used in large-scale concrete projects due to their high precision, high efficiency and high-quality construction advantages, but their high cost and technical requirements also make them have certain limitations in small projects or complex scenes. Construction units can weigh their advantages and disadvantages according to the project scale, precision requirements and budget, and choose the appropriate construction equipment.       Click the below to jump immediately!!!
