What is the principle of infrared laser concrete leveling machine?

Specification for flatness of concrete floors As a ground material widely used in modern buildings, compacted soil floor has the advantages of high strength, durability and easy maintenance. However, flatness is an important indicator of concrete floors, which directly affects the use function and appearance quality of the ground. Therefore, formulating specifications for ground flatness of compacted soil is of great significance to ensure project quality. 1. Ground flatness refers to the maximum distance the ground surface deviates from the datum plane in the horizontal direction. For general indoor concrete floors, the flatness should not be greater than 2mm/2m. For floors with special requirements, such as clean workshops, precision instrument rooms, etc., corresponding adjustments should be made according to the usage requirements. 2. The allowable deviation of flatness should take into account factors such as usage requirements, construction conditions, construction methods, etc. Generally speaking, there are the following regulations for the allowable deviation of flatness when inspected using a 3m ruler and feeler gauge: a) The 3m ruler shall not be larger than 3mm/2m; b) The independent column is not larger than 3mm/3m; c) The unevenness between two adjacent plates shall not be greater than 2mm; d) The total length shall not be greater than 10mm. 1.3m ruler inspection method: Use a 3m ruler placed vertically on the ground, observe the maximum gap between the ruler and the ground, and use a feeler gauge to measure the minimum gap. 2. Level measurement method: Set level points on the ground, measure the elevation of each point with a level, and calculate the flatness of the ground. 3. Laser scanner measurement method: Use a laser scanner to scan the ground, obtain point cloud data, and calculate the flatness of the ground through software analysis 1. Appearance requirements: The ground surface should be smooth, clean, without cracks, and uniform in color: anti-slip ramps should meet the design requirements. 2. Flatness requirements: Determine the corresponding acceptance standards based on actual conditions such as usage requirements, construction conditions, and construction methods. It is generally required that the flatness of the ground should not be greater than 2mm/2m, the independent columns should not be greater than 3mm/3m, the unevenness between two adjacent boards should not be greater than 2mm, and the total length should not be greater than 10mm. 3. Safety requirements: Anti-slip ramps should be installed on the ground, and their anti-skid performance should meet the design requirements. At the same time, for floors with waterproofing requirements, waterproofing treatment should be carried out and the next process can be carried out only after passing the inspection. 4. Functional requirements: The ground should have sufficient bearing capacity to meet the usage requirements. For example, for the concrete floors in workshops, the vibration and impact effects of vehicles when driving should be considered; for public buildings such as offices and libraries, noise interference should be avoided. 5. Durability requirements: The ground should have good durability and be able to maintain its performance and appearance quality for a long time. Durability requirements include wear resistance, corrosion resistance and aging resistance. 6. Economic requirements: On the premise of meeting the use requirements and construction quality, the project cost should be reduced as much as possible. Selecting appropriate construction materials and construction techniques, improving construction efficiency and quality stability, and reducing maintenance costs are key measures to achieve economic requirements. 7. Maintainability requirements: The ground requires regular maintenance and upkeep during use to ensure its performance and appearance quality. Maintainability requirements include ease of cleaning, ease of repair and ease of replacement. 8. Environmental protection requirements: Corresponding environmental protection measures should be taken during the construction process, such as reducing noise pollution, controlling dust, rational use of waste, etc.; at the same time, environmentally friendly materials and processes should be selected, such as energy-saving lighting, green building materials, etc. Note: The parameters provided in this document are for reference only and are not mandatory.

Before starting the ride-on trowel, carefully check all parts of the machine. Check whether the trowel blade is firmly installed and not loose, deformed or damaged. Because if the trowel blade falls off during operation, it may fly out at high speed and cause serious harm to the operator and surrounding personnel. At the same time, check the transmission parts, such as belts, chains or drive shafts, to ensure that they are properly connected and not excessively worn or loose, so as to avoid malfunctions during operation. Also check the control system of the machine, including the start button, speed adjustment knob, steering device, etc., to ensure that these parts can work properly. For example, the start button should be sensitive, the speed adjustment knob can accurately control the speed of the trowel, and the steering device should be flexible and effective to avoid accidents caused by control failure during operation.   The operator needs to be familiar with the conditions of the construction site in advance. Understand the size, shape, boundaries and ground conditions of the site, such as whether there are potholes, bumps, obstacles or water accumulation. For sloped ground, special attention should be paid to the size and direction of the slope, because the ride-on trowel may be out of control on a steeper ground. At the same time, ensure that there are no unrelated personnel or other equipment around the construction site, and set up obvious warning signs to prevent others from entering the construction area by mistake.   Operators must wear personal protective equipment. Including safety helmets to protect the head from possible collision injuries; protective gloves to prevent hands from being pinched by the rotating parts of the machine or scratched by sharp ground materials; protective shoes with anti-slip and anti-smashing functions to avoid slipping or heavy objects hitting the feet during operation. In addition, depending on the construction environment, earplugs (because the trowel is noisy when working) and goggles (to prevent dust and debris from entering the eyes) may also be required. When the operator is sitting in the driver's seat, he must maintain the correct driving posture, sit upright, hold the steering wheel or operating handle with both hands, and place his feet on the pedals (if there are pedals). When driving the trowel forward, backward or turning, operate smoothly and avoid sudden acceleration, sudden braking or sharp turns. For example, a sudden sharp turn when the trowel is running at high speed may cause the machine to roll over and cause a serious accident. Operate strictly in accordance with the operating instructions and do not arbitrarily adjust the machine's parameters or make unauthorized modifications. For example, do not operate beyond the speed range specified by the machine, because too high a speed will increase the risk of the machine losing control and is not conducive to obtaining a good troweling effect.   During operation, always pay attention to the operating status of the trowel. Observe the power system of the machine, such as the engine or motor, for abnormal noise, vibration or heating. If the machine is found to be underpowered, making abnormal sounds or vibrating violently, stop operating immediately, check the cause and troubleshoot before continuing to use it. At the same time, pay attention to the working condition of the trowel blade to see if the trowel blade is deflected, shaking or unevenly in contact with the ground. These problems may affect the trowel effect and cause damage to the machine.   When driving a trowel, keep a safe distance from surrounding buildings, walls, scaffolding and other fixed obstacles. It is generally recommended to keep a distance of at least 1-2 meters to prevent the machine from colliding with obstacles and being damaged or causing injuries to the operator. At the same time, keep a safe distance from other construction workers to prevent the rotating parts or moving body of the machine from hitting others. If other people need to enter the construction area, the operation of the machine should be stopped first and then continue after the people leave. When the trowel work is completed, park the machine in a safe place. Choose a flat, dry, and obstacle-free place to park, avoid parking the machine on a slope or unstable ground to prevent the machine from sliding or tipping over. If the machine needs to be parked for a long time, it is best to raise the trowel blade (if the machine has this function) to keep the trowel blade off the ground to reduce the corrosion of the trowel blade by ground moisture and prevent the trowel blade from contacting the ground and being damaged when accidentally started. After the machine is parked, it should be maintained according to the prescribed maintenance procedures. Clean the dust, concrete debris and other debris on the surface of the machine, and check whether the various parts of the machine are damaged or need to be replaced, such as the degree of wear of the trowel and the tightness of the transmission parts. Regular maintenance of the machine can extend the service life of the machine and ensure the safety and performance of the next use.   After each operation, the safety status of the machine should be checked and recorded. The record content includes whether the machine has a fault, whether maintenance has been performed, and the operation status of the operator. These records can help track the use and safety status of the machine, provide reference for subsequent operation and maintenance, and help to discover potential safety hazards in a timely manner.

    – The construction area of ​​this type of scene is usually small, generally between tens of square meters and hundreds of square meters. For example, the floor area of ​​the living room and bedroom of an ordinary residence may be around 20-50 square meters. The space is relatively narrow and there are many corners. – For this situation, a hand-held trowel with lower power is more suitable, with a power range of about 1-3kW. Because the low-power trowel has a small body and flexible operation, it can be easily moved in a limited space to perform trowel operations on narrow areas such as corners and walls.   – Common indoor floor materials include cement mortar floors, fine stone concrete floors, etc. The thickness of these floor materials is relatively thin, generally within a few centimeters. – The precision requirements are high, and the trowel machine needs to be able to finely process the floor to achieve a high degree of flatness and glossiness. The speed and trowel force of the low-power trowel machine are relatively moderate, which can just meet this demand and avoid damaging the surface structure of the floor material due to excessive power.   – The construction area is between a few hundred square meters and thousands of square meters, and the space is relatively open. For example, the area of ​​a medium-sized warehouse may be 500-2000 square meters. – You can choose a moderately powered walk-behind or ride-on trowel. The power of a walk-behind trowel is generally 3-5kW, and the power of a ride-on trowel is 4-7kW. Ride-on trowels are more efficient when constructing large areas, and can quickly smooth the ground, saving time. Walk-behind trowels can be used in some corners that are difficult for ride-on trowels to reach. – The ground material may be thick concrete, about 10-20 cm thick. In this case, the trowel needs to have enough power to compact and smooth the ground. – Although the precision requirements are not as high as those for small indoor scenes, it is still necessary to ensure that the ground has a certain degree of flatness and smoothness to meet the needs of cargo storage or equipment installation. Medium-power trowels can complete the troweling task well while ensuring efficiency.   – The construction area is very large, often exceeding thousands of square meters, or even tens of thousands of square meters. For example, a large city square may be 10,000 to 50,000 square meters in area, and an airport runway is even larger. – For this scenario, a high-power driving trowel should be selected, with a power of usually 7 to 15kW. Because large outdoor projects require a large amount of ground troweling work to be completed in a short period of time, a high-power trowel can provide sufficient power and high work efficiency to quickly cover a large area of ​​the ground. – The ground material is generally a thick layer of high-strength concrete, which may be about 20 to 50 cm thick. The trowel needs to have strong power to handle this thick and hard ground material. – For precision requirements, large squares require good flatness and drainage slope of the ground, while airport runways have strict specifications for indicators such as flatness and roughness of the ground. High-power trowel machines can precisely control the trowel effect by adjusting components such as the trowel blade to meet these high standards.
