Is it normal for the laser level to have heavy lines? How to solve it?

To ensure that the flatness of the concrete floor meets the requirements, the following aspects can be considered: 1. Preparation work before construction: Before construction, technical explanations should be conducted to clarify the requirements and standards for flatness, and construction personnel should be trained and assessed to ensure that they understand and can meet these requirements. At the same time, measurement and setting out should be carried out to determine the elevation and horizontal baseline as the basis for construction. 2. Reasonable design of concrete mix proportion: The mix proportion of concrete should be reasonably configured according to the design requirements to ensure the strength, durability and working performance of the concrete. During the configuration process, trial configuration and adjustment should be carried out to ensure that the various performance indicators of the concrete meet the requirements. 3. Quality control of formwork installation: Formwork installation is one of the key factors affecting the flatness of the concrete floor. Templates that meet specifications and quality should be selected and inspected and adjusted before installation. During the installation process, it is necessary to ensure that the splicing of the formwork is tightly supported and stable to avoid problems such as misalignment and slurry leakage. 4. Quality control of concrete pouring: During the concrete pouring process, the pouring speed and vibration quality should be controlled. Too fast a pouring speed may cause accumulation and unevenness of the concrete, affecting the flatness; insufficient or uneven vibration may cause problems such as honeycombing and pitting in the concrete. Therefore, the pouring speed should be reasonably controlled to ensure uniform distribution of concrete. At the same time, sufficient vibration should be carried out to ensure that the concrete is dense. 5. Quality control of surface treatment: After the concrete pouring is completed, the surface should be processed in time. The surface should be smoothed with a flat scraper and other tools, and rolled with a roller and other tools to ensure that the surface is smooth and dense. During the surface treatment process, care should be taken to avoid excessive smoothing and calendering to avoid problems such as cracks on the surface. 6. Quality control of later maintenance: After the concrete floor construction is completed, appropriate maintenance should be carried out to avoid problems such as cracking and shelling. Appropriate moisturizing measures should be taken, such as covering with straw bags, watering, etc., to keep the surface moist. At the same time, attention should be paid to controlling the curing time to avoid premature or too late curing that may cause quality problems on the surface. 7. Quality inspection and acceptance: After the construction is completed, the quality inspection and acceptance of the flatness of the concrete floor should be carried out. Corresponding detection tools and methods, such as 3m rulers, levels, etc., should be used to detect and record the flatness of the ground. Parts that do not meet the requirements should be processed and repaired in time to ensure that the final flatness meets the requirements. To sum up, to ensure that the flatness of the concrete floor meets the requirements, it is necessary to carry out sufficient preparations before construction, reasonably design the concrete mix ratio, and strictly control the quality of formwork installation, concrete pouring, surface treatment and post-maintenance at the same time. Quality inspection and acceptance. Only when these aspects are effectively controlled can the requirements for ground flatness be finally achieved.

[MANUAL PK EQUIPMENT] WHAT'S SO GOOD ABOUT VANSE LASER LEVELING MACHINE? We have all seen the exquisiteness of manual production, but after all, it is aimed at a small number of people and cannot be mass-produced, and manual work will prolong the construction time. Some time ago, VANSE Machinery specially conducted a man-machine battle, asking 8 senior technicians to compete with the laser leveling machine, and the result is self-evident. Concrete laser leveling machine has many advantages compared with traditional construction. Take the YZ30-4E concrete laser leveling machine as an example. After years of research and development, Shandong VANSE Machinery is the first to launch a laser leveling machine in China, which directly solves these troubles of customers . Let me tell you about the five advantages of our concrete laser leveling machine compared with traditional construction: About 8 workers use Wanshi laser leveling machine to form a construction team, which can complete 300 square meters of paving work per hour, and a single shift can complete 3000-5000 square meters. In large-area floor construction, manual construction with traditional techniques requires a team of about 15 people, and the workload of a single shift is within 700 square meters. The original labor needs to pay the formwork in advance, which wastes labor, delays the construction period, and cannot effectively return funds. Using VANSE concrete laser leveling machine, 3000-5000 square meters can be completed in one day. The original artificial formwork is supported in advance, the construction effect is low, and the construction period is prolonged. The working principle of VANSE Concrete Laser Leveling Machine is that the laser transmitter generates rotating laser, the laser receiver on the leveling machine receives the signal, and the laser measurement and control system analyzes it, and the deviation will be fed back to the sensitive computer control system on the leveling machine. The left and right electric push rods will adjust the height of the scraper to ensure leveling accuracy and high leveling. The technological principle of VANSE Concrete Laser Leveling Machine is to rely on gasoline generators to generate electricity, and use electric power to drive the laser measurement and control system, computer control system and servo drive system to use the leveling head to complete the leveling work. Laser leveling machine leveling does not need to pull the control line, and also There is no need for side templates to control the ground elevation, but it is controlled in real time by the laser measurement and control system on the leveling machine. As long as the laser transmitter is not disturbed, no matter where the leveling machine moves, the overall elevation of the paved ground can be ensured Not affected.   Our VANSE laser leveling machine uses a high-frequency vibrator of 4,000 times per minute. The uniform high-frequency vibration of the vibrating plate of the leveling head makes the concrete floor dense and can avoid ground cracks caused by stress concentration caused by deformation. It can reduce cracks and effectively solve the problems of hollowing, shelling, cracking and inequality on the ground.

The concrete laser leveling is a piece of equipment widely used in concrete construction. Its efficient flatness and precise elevation control have won the favor of the majority of constructors. In order to maintain its good working condition and extend its service life, regular maintenance and repairs are essential. The following is the maintenance process of concrete laser leveling machine. Daily maintenance: After each day's work, the following maintenance work should be performed. Clean the machine surface: Wipe the machine surface with a damp cloth to remove dust and debris.
