Combined with the German international advanced technology design, the product parts are manufactured in Europe, the United States and Japan international well-known brands, accurate and durable to ensure practical effect, system products have been widely used in the country's large enterprises workshop, floor engineering and other industries, has been highly recognized by the majority of users and partners. Shandong Vanse has developed and launched a number of high-tech new products such as "" brand concrete laser levelling machine, floor machine, four-drive concrete laser levelling machine, six-wheel laser concrete levelling machine, 360-degree steering large automatic laser levelling machine, paver and site-type polishing machine for many years, and created a unique set of new concrete (floor) ground construction process. The laser concrete leveling machine lays the cement concrete floor, which is much better than the ground laid by conventional methods – the ground flatness and levelness are increased by more than 3 times, and the density and strength are increased by 20 percent. At the same time, it can improve efficiency by more than 50 percent and save about 35 percent of labor. In addition, it can easily lay high-strength concrete, low-slump concrete and steel fiber mud condensate. The laser system is equipped with a variety of automatic control elements to monitor the elevation of the straightening head in real time at a frequency of 10 times per second to ensure that the surface flatness and levelness of the paving are effectively controlled. At the same time, its strong vibrator vibration frequency of 4000 times/minute, to ensure that the concrete vibration compaction, so that the entire concrete matrix is homogeneous and dense. In the 21st century of economic globalization, with the development and rapid popularization of China's floor industry, the floor industry is increasingly prosperous. The traditional intensive labor operation mode has no longer adapted to the needs of development, and the integration, intelligence and automation of machinery and equipment will become the mainstream of The Times.

The working principle of the concrete trowel mainly involves the mechanical structure and working power of the machine. First, a concrete trowel is a machine driven by an electric motor or a fuel engine. When the machine is started, the motor or engine drives the reducer to transmit power to the trowel plate. A trowel is a rotating flat plate equipped with a grinding wheel. The grinding wheel is usually made of high-hardness abrasives or diamonds and can polish cement floors. Secondly, when the trowel moves flatly, it smoothes and polishes the cement floor. This is because the rotation and pressure of the trowel plate causes the grinding wheel to rub against the concrete floor, thereby grinding and polishing the floor. Through the adjustment device, the movement speed and angle of the trowel plate can be adjusted to meet different construction needs. In addition, the concrete trowel can also achieve different levels of floor polishing and smoothing by replacing different polishing heads. Different polishing heads can adapt to different concrete strength, texture and surface quality requirements. To sum up, the working principle of the concrete troweling machine is to use a motor or engine to drive the reducer and transmit the power to the troweling plate, so that the troweling plate can scrape and smooth the cement floor during planar motion. At the same time, the movement speed and angle of the trowel plate can be adjusted through the adjustment device to meet different construction needs.

    In the construction of large-area super-flat concrete floors, the pouring sequence and equipment scheduling are crucial for determining the overall integrity of the floor, minimizing cold joints, and ensuring the FF/FL index. Unlike ordinary concrete floors, super-flat floors emphasize **"continuity" and "rhythm"** during construction. Large-area construction typically employs the following two strategies, with the core logic being to control shrinkage stress: For VNA (Very Narrow Aisle) warehouses, long-strip pouring is usually adopted. Sequence: Long-distance longitudinal pouring along the aisle direction. For example, a 100m x 50m area would be divided into several strips 4m to 6m wide and 100 meters long. Advantages: Laser Leveling can maintain continuous operation over long distances, reducing transverse construction joints and significantly improving the FL (levelness) value. Sequence: The area is divided into blocks. Blocks 1, 3, and 5 are poured first, and after they have stabilized from shrinkage (usually after 7 days), blocks 2, 4, and 6 are poured. Applicability: Suitable for sites with limited space or where structural design requires strict control of cracks Super-flat floor construction must achieve a balance where concrete supply speed = paving speed = finishing speed. Uniform Supply: The batching plant must dedicate specific tanks for continuous supply. The calculation formula is: V = W × H × v (Where V is the required material supply per hour, $W$ is the paving width, H is the slab thickness, and v is the forward speed of the leveling machine). Vehicle Spacing: The site must maintain a rolling pattern of "one truck unloading, one truck waiting, and one truck on the way," strictly prohibiting supply interruptions exceeding 15 minutes, otherwise visible leveling marks will occur. Starting and Finishing: The laser leveling machine should start from the short side. When approaching the edge of the formwork, manual material replenishment should be used. Overlap Control: Each paving pass should overlap the previous pass by 20-30 cm to eliminate elevation differences at the overlap. Finishing is a relay race, usually requiring 3-4 ride-on power trowels working together: First Team (Slurry Application): Following closely behind the leveling machine, they enter the site when a person's footprint leaves an approximately 5 mm deep impression, using a pan to apply the slurry. Second Team (Leveling): Using a highway straightedge, they perform reciprocating adjustments in both longitudinal and transverse directions. Third Team (Fine Finishing): When the concrete surface begins to shine and the footprint depth is reduced to 2 mm, the blades are changed for high-speed finishing. Time points Construction Locations Equipment Status 6:00 Beginning of the first tunnel section The laser Leveling has started operation, and the first two concrete trucks have arrived. 9:00 Middle of the first tunnel section The power trowel team is entering the site; the long-handled Leveling is beginning initial leveling. 12:00 End of the first tunnel section The laser Leveling is moving to the second lane for preparation; the first lane is entering the final finishing stage. 15:00 Overall site maintenance Cover with plastic film or spray curing agent; personnel are strictly prohibited from stepping on the finished area. Equipment Failure: A backup laser Leveling or manual vibrating beam must be available on site. If the main Leveling breaks down and the work is stopped for more than 30 minutes, the floor's flatness will not meet the super-flat grade. Sudden Weather Changes: Sufficient rainproof tarpaulins must be prepared for large-area construction. Because super-flat floors are extremely sensitive to the surface water-cement ratio, finishing work is strictly prohibited in the rain.
