Precision Control Principle of Laser Leveling Machine in Superflat Floor Construction

  – Site size – For large-scale concrete construction sites, such as large industrial plants, warehouses, parking lots, etc., it is recommended to choose a ride-on trowel. The ride-on trowel has high working efficiency and can complete large-scale troweling work in a short time. For example, for the floor construction of a logistics warehouse with an area of ​​more than 1,000 square meters, a ride-on trowel can quickly perform rough and fine grinding, effectively saving time and manpower. – For small-area indoor floors or local repair work, a walk-behind or handheld trowel is more suitable. For scenes such as home indoor floor decoration and small store floor repair, the walk-behind trowel is flexible to operate and can easily operate in narrow spaces and corners. – Ground flatness requirements – If the flatness and finish of the ground are extremely high, such as the floor of a high-end shopping mall, the clean workshop of an electronics factory, etc., a double-disc trowel needs to be considered. The double-disc trowel can better ensure the flatness of the ground. Its two trowel discs work at the same time, which can reduce the height difference of the ground and make the ground achieve a mirror-like effect. – For general ground, such as outdoor roads in ordinary houses, simple activity venues, etc., a single-disc trowel can meet basic troweling needs. – Electric trowel – Advantages: The electric trowel has the characteristics of low noise and no pollution, which is suitable for use indoors or in places with high requirements for environmental noise. Moreover, the operation of the electric trowel is relatively simple, and it is convenient to start and stop. You only need to turn on or off the power. – Disadvantages: The working range of the electric trowel is limited by the length of the power cord. If the construction site is large, the socket position may need to be changed frequently. In addition, the power of the electric trowel is relatively weak. When facing thicker or harder concrete, it may be insufficient. – Gasoline trowel – Advantages: The gasoline trowel has strong power, is suitable for various types of concrete, is not limited by the site power supply, and has good maneuverability. It can be freely moved and operated in remote construction sites or large open-air sites without power supply. – Disadvantages: Gasoline trowels are noisy and produce exhaust emissions, which have a certain impact on the environment and the health of operators. In addition, its maintenance cost is relatively high, and parts such as engine oil and spark plugs need to be replaced regularly. – Size of trowel disc – The larger the size of the trowel disc, the larger the coverage area of ​​a single trowel and the higher the work efficiency. Generally, the diameter of the trowel disc of a hand-held trowel is between 600 and 1000 mm, and the diameter of the trowel disc of a ride-on trowel may reach more than 1000 mm. When choosing, determine the appropriate trowel disc size based on the size of the construction site and actual needs. – Speed ​​range – The appropriate speed is one of the key factors to ensure the quality of troweling. Too high a speed may cause the trowel disc to wear too quickly and cause defects such as wavy lines on the ground; too low a speed will affect the troweling efficiency. The speed of a general trowel is between 70 and 150 rpm. The speed range of trowels of different brands and models may vary, and needs to be selected according to specific construction requirements. – Power – The power determines the working capacity of the trowel. For large trowels or when thicker and harder concrete needs to be processed, higher power is required. For example, the power of a ride-on trowel is generally between 5 and 10 horsepower, the power of a walk-behind trowel is usually between 3 and 5 horsepower, and the power of a handheld trowel is relatively low, generally between 1 and 3 horsepower. – The consumable parts of a trowel mainly include trowel blades, bearings, drive belts, etc. When purchasing a trowel, consider whether these consumable parts are in sufficient supply and whether they are easy to purchase. For example, some niche brands of trowels may have consumable parts that are difficult to find, making repair and replacement inconvenient. At the same time, you should also compare the prices of consumable parts of different brands and models of trowel machines, and try to choose a trowel machine with lower consumable parts costs, so as to reduce the cost of later use and maintenance. – Brand reputation: Choosing a trowel machine from a well-known brand can usually guarantee the quality and performance of the product. Well-known brands have stricter standards in product research and development, production processes, quality control, etc., and their products are more reliable. For example, some brands with many years of production experience in the field of construction machinery have had long-term inspections on the market and received good user feedback. – After-sales service: Good after-sales service is an important factor in ensuring the normal use of the trowel machine. After-sales service includes product warranty period, timeliness and professionalism of maintenance services, technical support, etc. When purchasing, you should understand whether the manufacturer provides door-to-door maintenance services, the speed of supply of maintenance parts, and whether there is a professional customer service team to answer questions encountered by users during use.

  The concrete laser leveling machine significantly improves the construction accuracy through its high-precision laser control system and automated operation. During the construction process, the laser leveling machine uses the laser emitted by the laser transmitter as the reference surface, and controls the height of the leveling head in real time through the laser receiver to ensure that the ground flatness reaches the optimal state. This system can monitor and adjust the leveling head in real time to achieve high-precision ground elevation and flatness control.   In addition, the construction characteristics of the laser leveling machine include high flatness quality, greatly improved work efficiency, and good integrity of the ground concrete. By choosing the laser leveling machine for construction, fixed investment can be saved, labor costs can be reduced, and operating costs can be reduced. The wide application of concrete laser leveling machines has improved the green and environmental protection performance of the floor, and the supply of laser paving machine equipment market has also driven the development of floor equipment.   The construction process of the laser leveling machine includes construction preparation, concrete paving + laser leveling, initial grinding and breaking of concrete laser leveling machines, and throwing wear-resistant aggregates. Before construction, the laser transmitter is fixed, and the elevation of the finished surface is accurately measured using a leveling ruler. During the construction process, the laser leveler uses laser technology to automatically level and complete the leveling work under computer control. Since the laser transmitter is fixed, it ensures that there is no cumulative error in the construction of a large area of ground, and ensures that the elevation of the ground after pouring is not affected.   In summary, the concrete laser leveler significantly improves the construction efficiency and quality through its automation and high precision. It is suitable for large-area floor construction projects, especially in projects with tight schedule requirements, large paving areas, and high quality requirements.
