The advantages of laser leveling machine are revealed, don’t be convinced!

    Concrete laser leveling machines play a revolutionary role in modern floor construction. Their importance can be comprehensively explained from multiple core dimensions such as project quality, construction efficiency, economic benefits and labor intensity. It not only simply replaces the traditional manual scraping tools, but also fundamentally improves the craftsmanship and standards of floor construction.   This is the core and most important value of the laser leveling machine. Traditional technology: relies on manual formwork, string pulling, and ruler scraping, which is greatly affected by workers' experience, physical strength, and visual judgment, resulting in large errors and difficulty in ensuring overall consistency. Laser leveling machines use a precise optical plane established by a laser transmitter as a single reference, ensuring absolute horizontality and stability within the construction area. A receiver on the leveling acquires elevation information in real time, and the control system automatically and precisely drives the scraper for leveling. Result: F can be easily achieved₃₀ ≥ 90%, F₄₀≥ 70% or even higher, the industry's highest flatness standards. This level of accuracy is unattainable by manual labor and is particularly suitable for applications with extremely high floor requirements, such as large logistics warehouses, automated production lines, and super-large shopping malls. Traditional construction often requires separate formwork and pouring in multiple compartments, which results in numerous construction joints. These joints are both weak points and the starting point for future damage. The laser leveling machine has extremely high construction efficiency and can achieve large-scale continuous pouring (the construction area in a single day can reach more than 2,000 square meters), greatly reducing the number of construction joints, and forming a concrete floor with better integrity and more stable structure. The tamping plate and high-frequency vibrator of the leveling machine will fully vibrate and compact the concrete before leveling, effectively eliminating bubbles, avoiding aggregate separation, and evenly distributing the concrete slurry, thereby obtaining a denser, more uniform, and higher-strength surface, greatly reducing common quality problems such as sanding, hollowing, and cracks.   A laser leveling machine can achieve an efficiency of 100-200 square meters per hour, 10-20 times that of traditional manual levelinging. This means project duration can be significantly shortened, giving owners valuable time to start production earlier and create value. Large-scale construction does not require waiting for tedious processes such as supporting and dismantling formwork, and realizes the integrated flow operation of concrete pouring, vibration, leveling, and slurry preparation. The processes are closely connected and the construction process is more scientific and reasonable.   Traditional processes require a large number of skilled plasterers, resulting in high labor costs and difficult personnel management. Using a laser leveling machine, the job can be completed by just one operator and several auxiliary workers (responsible for unloading, initial paving, etc.), reducing the number of workers and skill requirements, and significantly saving labor costs. The laser control system can accurately control the elevation and flatness of the floor, avoiding concrete waste caused by over-thick pouring, and also avoiding the cost of secondary filling due to insufficient elevation, thus achieving precise control of concrete usage. Because the molded floor is of high quality, strong and has good integrity, it is wear-resistant and durable during use and not easy to be damaged, which greatly reduces future maintenance and repair costs.   It frees workers from heavy, high-intensity bending labor and transforms them into equipment operation and technical supervision roles, improves working conditions, and conforms to the humanistic trend of modern engineering management. Construction quality no longer relies excessively on individual workers' skills and sense of responsibility. As long as the equipment is debugged accurately, no matter who operates it, the same high-standard product can be produced, achieving controllable, standardized, and industrialized construction quality. Workers do not need to walk back and forth on the unset concrete surface, reducing safety hazards.   The importance of concrete laser leveling machine in construction can be summarized as follows: In terms of quality: It is an indispensable core equipment for building ultra-high precision, high strength and high integrity modern industrial floors. In terms of efficiency: it is a powerful engine that significantly shortens construction period and speeds up project progress. Economically: It is a key tool to reduce comprehensive costs (labor, materials, maintenance) and improve the return on project investment. In terms of management: it transforms floor construction from a "craft" to an "industrial process", realizes standardized production, and represents the development direction of modernization of construction. Therefore, in today's context of increasing quality requirements for large-area concrete floors, laser leveling machines have changed from "optional equipment" to "necessary equipment" and have become standard equipment for high-quality flooring projects.

  In order to ensure the construction quality of concrete floor, more and more construction units now choose to use precision laser leveling machines to lay concrete floor. However, in the actual construction process, due to the inadequate cooperation of some enterprises in construction, or not strictly following the regulations to operate correctly, the quality of concrete floor construction is sometimes poor. In order to avoid such a situation from happening again, our company has made a detailed description of some matters related to the construction cooperation during the construction of the laser leveling machine. We hope that the relevant construction personnel will keep it in mind. ❖Wall line laying and leveling: Since the laser leveling machine cannot touch the wall, manual leveling is required within 200mm from the wall, so it is necessary to lay out the line as a reference for manual leveling. At the same time, set 2 to 3 leveling base points (ground design elevation, i.e. ±0.0) that are not disturbed during the construction period for the laser leveling machine to use at one time, and require good mutual visibility. Leveling point accuracy ±1mm. ❖Set templates (steel templates, the position is determined according to design requirements) around the columns to form separation seams. The elevation of the top surface of the template should be controlled within +0mm and -2mm to avoid affecting the flatness of the joints. ❖Installing construction joint formwork: Install the construction joint template along the range to be poured on the day (steel template is recommended), and the template should reserve holes with a spacing of 300mm for the insertion of the force transmission rod. The elevation of the top surface of the template should be controlled within +0mm and -2mm to avoid large deviations in the flatness of the joints of different bins.   ❖Laser transmitter installation: It is planned to be installed on the column. The specific location should be set at a better location according to the amount of paving on the day. If it cannot be installed on the column, it should be installed on a special tripod.   ❖In order to ensure the quality of concrete floor paving, each group needs to arrange 10 to 12 workers to cooperate to flatten the surface of the concrete spread on the ground so that the pile is slightly higher than the design elevation (about 20 to 30mm). At the same time, for the parts near the wall, exposed pipelines and the surrounding of the formwork, two workers are arranged to manually smooth the concrete material about 20~30cm away from the wall (formwork) (using a 2m scraper with an iron trowel). The workers responsible for smoothing the edges must be trained and skilled plasterers. These workers must obey the command and follow the arrangement to ensure the quality of construction.   ❖ Since the thickness of the concrete reaches 200mm, and because of the installation of steel mesh, in order to ensure the compaction of the concrete, this project needs to arrange a vibrating rod to cooperate with the vibration. At the same time, in order to ensure that the protective layer of the steel mesh reaches the design requirement of thickness (70mm), it is necessary to arrange for manual lifting of the steel mesh and pad the support block in the range to be paved in advance.   ❖ The width of the concrete material paved on the platform each time is required to be no more than 5m, and the length is based on the formwork boundary. The construction direction is from left to right (along the short side direction) and from front to back (along the long side direction). The recommended daily paving volume is 1200~1500㎡. Calculated based on 12 hours of working time per day, the feed rate is required to be 30 to 40m³.   ❖Others: To ensure the flatness of the ground, special attention should be paid during the construction of the laser leveling machine: the slump of the concrete delivered to the platform each time must be consistent; the concrete feed rate must reach 40m. per hour or more, and the initial setting time of each batch of concrete must be consistent; the template elevation must be accurate and cannot be disturbed during construction; environmental coordination. The newly constructed concrete floor cannot be exposed to sunlight, wind, rain and other environments that are unfavorable to the curing of concrete.   Special reminder: In order to make the laser leveling machine give full play to its inherent functions and ensure the construction quality and efficiency of the concrete floor, in addition to mastering the above-mentioned construction coordination precautions, there are many details that need to be paid attention to. Please look forward to the subsequent updates and sharing of this site.

    Laser leveling machine is a kind of equipment used for large-area concrete paving and leveling. There are special operating skills in different construction environments:   – Indoor space is usually limited, and the size of laser leveling machine is relatively large. Before entering the indoor construction site, accurately measure the size of doors, passages, etc. to ensure that the machine can enter smoothly. If the passage is narrow, some parts, such as detachable scrapers, may need to be removed and installed after the machine enters the room. – During operation, pay attention to the turning radius of the machine due to limited indoor space. Plan the leveling route in advance and minimize the machine's large-scale turning movements to avoid colliding with walls, columns and other building structures. – Pay special attention to dust control during indoor construction, because dust will affect indoor air quality and subsequent decoration processes. The laser leveling machine can be equipped with an efficient dust suction device to simultaneously remove dust during the leveling process. – For situations where there are more loose debris on the ground, use a broom or industrial vacuum cleaner for preliminary cleaning before construction to reduce the situation of debris being raised during the leveling process. – Indoor floors usually have high requirements for flatness, such as warehouse floors, exhibition hall floors, etc. Before construction, carefully calibrate the laser transmitter and receiver to ensure the accuracy of the laser signal. – According to the designed slope of the indoor floor (if any), accurately set the control system parameters of the laser leveler. For example, for indoor floors with drainage requirements, the leveling operation should be carried out according to the designed drainage slope (such as 0.3% – 0.5%), and the flatness should be checked regularly during the construction process. Tools such as rulers can be used for random inspections.   – If there is an uneven original ground on the construction site, such as potholes, bumps, etc. Before construction, use equipment such as bulldozers to perform preliminary leveling on the site and deal with areas with large height differences. For small potholes, the thickness of the concrete can be appropriately increased during the construction of the laser leveler to fill them. – When the site has a certain slope, the working mode of the laser leveler should be adjusted according to the design requirements. For example, for the gentle slopes at the entrance and exit of the parking lot, they should be leveled according to the specified slope (such as no more than 7% – 10%), and the transition with the adjacent plane area should be natural and smooth. – Weather factors have a greater impact on outdoor construction. If high temperatures are encountered, the solidification speed of concrete will be accelerated. The leveling construction speed should be appropriately accelerated, and retarders can be added to the concrete to extend the working time of the concrete. At the same time, attention should be paid to providing heatstroke prevention measures for operators. – When encountering rainy weather, the laid but not completely solidified concrete should be covered with plastic film in time to prevent rain erosion. If there is water accumulation on the ground, drain it before construction, and check the water content of the ground to avoid affecting the quality of concrete due to excessive water content. – For large outdoor sites, in order to improve construction efficiency, multiple laser leveling machines can be used for collaborative operation. When dividing the construction area, the walking route of the machine should be reasonably planned to avoid mutual interference. – Arrange the supply of concrete in advance to ensure that concrete can be supplied to the construction area continuously and stably. Concrete mixer trucks can be used to unload directly near the construction area to reduce the concrete transportation time and improve the overall construction progress.   – When constructing on narrow roads or corridors, the positioning of the laser leveler must be accurately controlled. Due to the narrow space, the machine may not be able to perform regular steering operations. The concrete can be spread and leveled by adjusting the angle of the scraper by alternating forward and backward movements. – Set up warning signs on both sides of the road or corridor in advance to prevent other vehicles or personnel from interfering with the construction, and also to avoid the machine from colliding with roadside facilities. – When constructing in narrow spaces, the safety of the operator is of vital importance. The operator should wear protective equipment, such as a helmet, reflective vest, etc. And ensure that the machine's emergency brake is in good condition so that it can stop in time in case of an emergency. – As roads or corridors may have a certain amount of traffic flow, during construction, it is necessary to work closely with on-site traffic management personnel and select periods with less traffic flow for construction, or adopt temporary traffic control measures.
