Concrete laser levelings and pavers are two different mechanical equipment with different functions and application fields. Here are their main differences: ※Working principle The concrete laser leveling machine uses laser measurement technology to emit a laser beam through a laser transmitter. The laser receiver receives the reflected laser signal and calculates the distance and direction of the leveling machine's movement, thereby accurately controlling the leveling machine's traveling route and direction. height to achieve the purpose of leveling the concrete surface. A concrete paver is a mechanically or hydraulically driven mixing device that mixes the concrete evenly and then spreads the concrete onto the working surface through a conveyor belt or scraper. It relies on the mixing device and the conveying device to complete the concrete laying operation. ※Application fields Concrete laser leveling machines are mainly used for leveling operations in large-area concrete projects, such as highways, bridges, parking lots, etc. It has the advantages of high precision, high efficiency, automation, etc., and can complete the leveling work of a large number of concrete surfaces in a short time. Concrete pavers are mainly used for laying concrete projects. It can lay various concrete structures, such as floors, walls, floors, etc. ※Operation method Concrete laser levelings usually use automated control systems that can be operated via a computer or remote control. The operator only needs to set relevant parameters and routes, and the leveling machine can automatically perform leveling operations. Concrete pavers are relatively simple to operate. Operators need to master the operating skills of mechanical equipment and the process requirements of concrete mixing, and complete the concrete laying operation by controlling the mixing device and conveying device. ※Processing quality Due to the use of laser measurement technology, the concrete laser leveling machine can complete large-area leveling operations in a short time and can achieve high precision and flatness. It can control the flatness error of the concrete surface within a small range and improve the quality and service life of the concrete surface. The quality of concrete paver processing depends primarily on the skill and experience of the operator. If the operator has rich experience and high skill level, he can achieve better laying results. However, if the operator's technical level is not high or unskilled, it may lead to uneven or uneven laying, affecting the processing quality and service life. ※Processing efficiency The processing efficiency of concrete laser leveling machines is usually high. It can achieve automated control and high-precision measurement to complete the leveling operations of a large number of concrete surfaces in a short time. At the same time, due to the use of laser measurement technology, it can avoid errors and delays in traditional measurement methods. The processing efficiency of concrete pavers is relatively low. It requires operators to manually control the parameters and time of the mixing device and conveying device, thus requiring more time and manpower to complete large-area concrete projects. ※Maintenance and care Maintenance and maintenance of a concrete laser leveling is relatively simple. It requires regular inspection of the cleanliness and accuracy of the laser transmitter and receiver, as well as routine lubrication and maintenance of the machine. At the same time, regular cleaning and maintenance of the machine is also required to maintain the normal operation and service life of the machine. Concrete pavers are relatively complex to maintain and maintain. It requires regular inspection of the working status of the mixing device, conveying device and engine, as well as regular lubrication and maintenance of the machine. At the same time, the equipment also needs to be cleaned and maintained regularly to extend the service life of the machine. To sum up, although concrete laser levelings and pavers are used for the treatment and paving of concrete surfaces, their working principles, application fields, operating methods, processing quality, processing efficiency and maintenance are all different. Certain differences. When choosing to use it, you need to choose appropriate mechanical equipment according to the actual situation to meet the construction requirements.

– Using laser leveling technology, the laser transmitter generates a precise and stable plane reference. The laser receiver is installed on the leveling machine to sense the deviation in real time, so that the leveling machine automatically adjusts the scraper height to ensure that the floor flatness error is extremely small, which can generally be controlled within ±1.5mm, and can meet the needs of high-end industrial plants, electronic chip manufacturing workshops and other places with strict requirements on flatness. – Optimize the concrete mix ratio, add appropriate amounts of expansion agents, fibers and other admixtures, reduce the shrinkage stress during the hardening process of concrete, and cooperate with the carefully designed construction process, so that the floor does not need to set expansion joints in a large area, which is not only beautiful but also reduces the later maintenance cost, and avoids the accumulation of dust and debris caused by cutting seams. – In the initial setting stage of concrete, wear-resistant materials such as corundum and metal aggregates are evenly spread, and a special trowel is used to closely combine with the floor to form a hard and wear-resistant surface layer. The wear resistance can be several times higher than that of ordinary concrete floors. It is suitable for places with frequent wear and tear such as heavy traffic areas, warehouses, and logistics centers. – From base treatment, concrete pouring, leveling to wear-resistant material spreading, troweling and finishing, the processes are closely connected and completed in one go, avoiding the problem of poor interlayer bonding caused by layered construction, improving the overall strength and durability of the floor, and reducing the construction period. It can usually shorten the construction period by 1/3 – 1/2 compared with traditional processes. Applicable to indoor and outdoor concrete floor projects with large areas and high requirements for flatness and wear resistance, such as various large industrial plants, logistics storage centers, airport terminals, exhibition halls, parking lots, etc., especially suitable for places where obvious expansion joints are not expected to affect the appearance or use function. – The laser transmitter emits a rotating laser beam to form a high-precision horizontal control surface. The laser receiver installed on the leveling machine continuously captures the laser signal, compares the actual elevation of the floor with the laser plane benchmark, and transmits the generated deviation signal to the control system. The control system drives the hydraulic actuator of the leveling machine to adjust the scraper, vibrator and other components in real time to accurately level and vibrate the concrete to achieve high-precision leveling. – On the one hand, by optimizing the concrete mix ratio, selecting low-hydration hot cement, adding an appropriate amount of expansion agent (such as calcium sulfoaluminate expansion agent) to compensate for concrete shrinkage, adding polypropylene fiber to enhance concrete toughness and inhibit the generation of microcracks; on the other hand, during the construction process, strictly control the concrete pouring temperature, vibration method and curing conditions, reasonably arrange the construction sequence, reduce the temperature difference between the inside and outside of the concrete and stress concentration, so that the floor itself has the ability to resist shrinkage and deformation, thereby meeting the requirements of no seam cutting. – The surface of concrete in the initial setting stage has a certain viscosity. At this time, the spread wear-resistant material can be embedded in the surface of the concrete. With the subsequent leveling and finishing operations, the wear-resistant material and the concrete form a solid whole. Wear-resistant materials such as corundum and metal aggregates have high hardness and strong wear resistance, forming a wear-resistant protective layer on the surface to protect the main concrete of the floor from wear. – Technical preparation: Familiar with the construction drawings and technical specifications, formulate detailed construction plans, and conduct technical briefings. – Site preparation: Clean up the site debris and accumulated water, level the base layer, and if the base layer is soft soil, it needs to be reinforced; set up a temporary drainage system for construction; plan the concrete pouring and leveling route according to the site area and shape. – Material preparation: Purchase high-quality cement, sand, gravel, admixtures, wear-resistant materials, etc. according to the design requirements, inspect the raw materials to ensure that they meet the quality standards; prepare sufficient construction water and electricity. – Equipment preparation: Debug concrete laser leveling machine, concrete mixing equipment, transportation equipment, wear-resistant material spreader, trowel, etc. to ensure the normal operation of the equipment; calibrate the laser system so that the laser plane it emits is consistent with the designed elevation of the floor. – Thoroughly clean the surface of the base to remove pollutants such as dust and oil; compact the base with a roller or tamping machine to achieve a compaction degree of more than 90%; repair and fill local low-lying areas and potholes with concrete or mortar to ensure that the flatness error of the base does not exceed ±10mm. – Accurately weigh the raw materials according to the designed mix ratio, use a forced mixer to mix the concrete, and the mixing time is not less than 90 seconds to ensure the uniformity of the concrete; transport the concrete to the construction area by pumping or unloading, control the pouring speed, avoid concrete segregation, and the pouring thickness is slightly higher than the designed floor elevation by 10-20mm to reserve space for leveling. – Start the laser leveling machine and make it move forward at a uniform speed of 1-2m/min; the operator adjusts the scraper height and vibration frequency of the leveling machine in real time according to the feedback signal of the laser receiver to ensure that the concrete surface is flat and compacted; the leveling work of adjacent areas should be completed before the initial setting of the concrete, and the overlapping construction width should not be less than 10cm to ensure the integrity of the floor. – When the concrete is initially set (generally there are slight footprints when stepping on it, and the sinking depth is about 3-5mm), use a special spreader to evenly spread the wear-resistant materials on the floor surface according to the specified amount, and the spreading thickness is generally 3-5mm; during the spreading process, pay attention to controlling the spreading speed and direction to avoid accumulation or leakage of wear-resistant materials, and ensure that the spreading uniformity reaches more than 90%. – After spreading the wear-resistant material, use a trowel to smooth it immediately. The trowel should run in a crisscross pattern to fully blend the wear-resistant material with the concrete. The number of smoothing passes should be no less than 3 times. As the concrete continues to harden, when there is no water stain on the surface and it feels slightly hard when pressed with fingers, it should be smoothed manually. Aluminum alloy rulers, trowels and other tools should be used to make the floor surface bright and smooth. – After smoothing and finishing, the floor should be maintained in time by covering with plastic film, spraying curing agent or laying water straw mats. The maintenance time should be no less than 7 days. During this period, the concrete surface should be kept moist to avoid water loss and cracks. Warning signs should be set up during the maintenance period to prohibit vehicles and pedestrians from passing on floors that do not meet the strength requirements. – Calibrate the laser system before construction to ensure the accuracy of the laser plane; regularly check the flatness with a 2m ruler and a feeler gauge during construction, at least once every 100-200 square meters, and adjust the leveler in time if deviation is found; use a laser flatness meter to fully test the flatness of the floor after finishing to ensure that it meets the design requirements. – Strictly select wear-resistant materials according to design requirements and check the quality certification documents of wear-resistant materials; supervise the spreading amount and uniformity during spreading to ensure that the specified requirements are met; after maintenance, on-site wear resistance tests can be carried out, such as grinding a certain area with a grinding wheel, observing the wear condition, and judging whether the wear resistance meets the standard. – Optimize the concrete mix ratio, control the cement dosage and water-cement ratio; monitor the concrete pouring temperature to avoid high-temperature pouring; strengthen maintenance and control the temperature difference between the inside and outside of the concrete; regularly inspect the floor, and if fine cracks are found, use epoxy resin and other materials to repair them in time. 1. Provide safety training to construction personnel to familiarize them with the operation methods and safety precautions of construction equipment, such as the safety operating procedures of laser levelers, concrete mixers and other equipment. 2. Set up obvious safety warning signs at the construction site to divide the construction area and non-construction area to prevent unrelated personnel from entering the construction danger zone. 3. Regularly check the safety performance of construction equipment, such as electrical insulation, mechanical protection devices, etc., to ensure the normal operation of the equipment and avoid safety accidents caused by equipment failure. 4. Provide construction personnel with necessary personal protective equipment, such as safety helmets, safety shoes, gloves, etc., to ensure the personal safety of construction personnel. 1. Classify and collect solid waste such as concrete residues and discarded wear-resistant material packaging bags generated during the construction process, and transport them to designated garbage disposal sites regularly. 2. Reasonably arrange construction time to avoid high-noise concrete mixing, equipment operation and other operations during residents' rest time. If necessary, take noise reduction measures, such as installing silencers on equipment. 3. Control dust on the construction site, such as covering the material storage area, closing the transport vehicles, regularly sprinkling water to reduce dust, and keeping the construction site clean. – The one-time molding process shortens the construction period, reduces labor costs, equipment rental costs, etc.; no cutting reduces the later maintenance costs, such as cutting, caulking material costs and labor maintenance costs; wear-resistant flooring increases the service life of the flooring, reduces the frequency of flooring replacement, and the overall economic benefits are significant.   – It provides high-quality flooring solutions for various large-scale projects, meeting the needs of rapid development of modern industry, logistics and other industries; it reduces noise, dust and other pollution during construction, which is conducive to environmental protection and sustainable development of urban construction. In a large electronic chip manufacturing plant construction project, this construction method was used to successfully create a high-precision, no-cutting, wear-resistant factory floor. The construction area reached 50,000 square meters, and the flatness error was controlled within ±1mm, meeting the stringent requirements of chip manufacturing equipment for floor flatness. In the subsequent years of use, the floor had good wear resistance and no obvious cracks appeared, providing a solid guarantee for the efficient production of the factory. For example, in a certain international logistics and warehousing center project, this construction method also performed well, and a large area of ​​floor was built quickly and efficiently. The seam-free design improved the aesthetics and practicality of the warehouse and was highly recognized by the owner.
