How to realize intelligentization and automation of concrete laser leveling machine?

1. Material problems ○ Improper concrete mix ratio, too little cement content or too high mud content in sand will lead to insufficient ground strength and easy sanding. ○ The strength grade of the selected cement is not enough to meet the construction requirements. 2. Construction problems ○ Improper operation of the laser leveler, such as too fast leveling speed, leads to insufficient density of concrete. ○ Poor grasp of the finishing time, too early or too late finishing will affect the quality of the ground. ○ Inadequate maintenance, concrete lacks water during the hardening process, affecting the development of strength. 3. Environmental problems ○ Too high or too low construction environment temperature will affect the coagulation and hardening of concrete and increase the risk of sanding. ○ Low air humidity and too fast evaporation of water on the concrete surface can also easily lead to sanding. 1. Material aspects ○ Optimize the concrete mix ratio, ensure moderate cement content, and control the mud content of sand. ○ Choose cement with appropriate strength grade to ensure the strength requirements of the ground. 2. Construction ○ Operators should be proficient in the use of laser leveling machines, control the leveling speed, and ensure the density of concrete. ○ Accurately grasp the finishing time, generally finishing after the initial setting of concrete and before the final setting. ○ Strengthen maintenance, such as covering with plastic film and sprinkling water to keep the concrete surface moist, and the curing time is not less than 7 days. 3. Environmental ○ Adjust the construction time and maintenance measures according to the ambient temperature to avoid construction under extreme temperatures. ○ In a dry environment, the number of sprinkling water can be appropriately increased to maintain the humidity of the concrete surface.

    There are significant differences in the selection considerations of concrete laser leveling machine for indoor and outdoor projects, mainly due to the differences in engineering environments, concrete properties, technical requirements, and the quality goals of the final products. The following will elaborate on this differentiated consideration in detail from multiple dimensions: Interior engineering: Greater emphasis is placed on precision, efficiency, flexibility and environmental protection. The ground, as the final finish or the foundation for supporting precision equipment, has extremely high requirements for flatness and levelness. Outdoor engineering: More emphasis is placed on equipment power, passability, anti-interference ability and adaptability to the base layer. In the face of harsh environments, large aggregate concrete and complex base conditions, the stability and "brute force" of the equipment are the key. Dimension of consideration Dimension of consideration Interior engineering Outdoor engineering 1. Ground accuracy requirements Extremely high Relatively low The flatness (FF/FL) requirement is high, and it is often necessary to meet the super-flat floor standard (such as FF≥50, FL≥35). Most of them are road surfaces, storage yards, squares, etc., and the requirement for flatness is lower than that for indoor areas. It is used in warehouses, logistics centers, precision manufacturing workshops, etc., directly affecting the operational efficiency of equipment and the stability of shelves. The allowable error range is larger, but it is necessary to ensure that the drainage slope meets the design requirements. 2. Device type preference First choice: Wheeled concrete laser leveling machine First choice: Wheeled (large tire) laser leveling machine • Advantages: Low grounding specific pressure, which will not cause damage to the base layer or the already laid steel mesh. It walks smoothly with low vibration and has the highest leveling accuracy. It turns flexibly and is suitable for areas with complex shapes. • Advantages: Good mobility and fast transfer speed; It has a high ground clearance, strong passability and can adapt to uneven base surfaces. Tires have better tolerance for rough substrates. 3. Grassroots conditions and passability Good conditions The conditions are complex and changeable. The base layer is usually compacted and leveled, with a smooth and solid surface. The base layer may be compacted soil base or crushed stone layer, which may be uneven and soft. There may be obstacles such as columns and walls in the space, which requires the equipment to be mobile and flexible. There may be slopes and potholes, so the equipment is required to have good passability and strong driving force. 4. Concrete properties The slump is small Large slump and large aggregate Most of them are fine aggregate concrete with small aggregate particle size and low slump (dry-hard concrete), which is convenient for laser leveling machines to complete compaction and leveling in one go. Coarse aggregate concrete is often used, and the aggregate particle size is large. The slump may be relatively high, and the requirements for the disturbance and subsidence control capabilities of the leveling are different. 5. Laser system High precision and multi-adaptability Strong anti-interference ability A laser system must be used and the accuracy of the receiver is required to be high. Both laser systems and GPS systems can be used. In multi-storey buildings, the deflection of floor slabs needs to be taken into account. Sometimes, multi-point laser or GPS systems are required to simulate the preset camp. GPS has obvious advantages in large outdoor areas, with no problem of visual obstruction and no need to frequently move base stations. The laser system needs to take into account the influence of strong outdoor light and strong wind on the stability of the laser signal. 6. Power system Mainly electric or electric + hydraulic Mainly high-power diesel engines • Electric: Zero emissions, low noise, highly suitable for construction in confined Spaces, meeting indoor environmental protection requirements. • Diesel engine: It offers powerful traction and vibration power, capable of handling large-aggregate concrete and complex substrates. The power demand is relatively low. The requirements for emissions and noise are relatively lenient. 7. Environmental Protection and Working Environment Demanding The requirements are lenient It must be low-noise and have zero emissions to avoid polluting the indoor air. It has relatively low requirements for noise and emissions. The size of the equipment should take into account the size restrictions of construction elevators and door openings. The working environment is harsh (sun exposure, rain, and dust), which requires the equipment to have a high protection level and a sturdy and durable structure. 8. Construction efficiency and area High efficiency, medium and small area Continuous operation over an extremely large area The daily construction area is large, but the individual operation surface is usually smaller than the outdoor area. It is commonly seen in airports, highways and large squares, with a huge single pouring area. Efficiency is reflected in the rapid leveling with high precision, reducing subsequent manual repairs. Efficiency is reflected in the continuous and uninterrupted large-scale paving and leveling capabilities. Step 1: Clarify the project attributes (indoor/outdoor) If it is an interior project Precision requirement: Does it meet the standard of super-flat floor? Yes -> Give priority to high-precision tracked types. Space limitations: Are there any obstacles such as columns or walls? Is the size of the door opening restricted? Yes -> Choose small-sized or equipment with column anti-blocking function, such as Vanse YZ30-4E Environmental protection requirements: Is it a sealed or clean environment? Yes -> Electric power must be chosen. Concrete type: Is it fine aggregate low slump concrete? Yes -> Suitable for all types of levelings. If it is an outdoor project Area and terrain: Is the area large (> 10,000 square meters) and the terrain open? Yes -> Give priority to wheeled +GPS systems. Base conditions: Is the base soft and uneven? It is -> Choose wheeled equipment with large tires, high ground clearance and strong driving force. Concrete type: Is it aggregate concrete? Yes -> Choose equipment with powerful vibration power. Slope control: Are there any complex requirements for the drainage slope? Yes -> The GPS system has more advantages in three-dimensional slope control (Vanse YZ30-4E/WS940C supports 3D system construction). In conclusion, choosing a concrete laser leveling machine for indoor and outdoor projects is essentially a trade-off between "precision" and "robustness". The core of interior selection is to find a "meticulous artist" who can carve out an extremely smooth floor within a small space in a clean environment. Wheeled, electric/diesel, and high-precision laser are its labels. The core of outdoor selection is to find a "strong warrior" that can overcome wind, rain and rough terrain, and efficiently complete the paving task in the vast expanse of the world. Wheeled and diesel power are its weapons. Correct selection not only ensures construction quality but also greatly enhances construction efficiency, reduces labor costs and safety risks. Therefore, before purchasing or leasing equipment, it is essential to conduct a comprehensive assessment based on the specific characteristics of the project.
