Comparison of Traditional Technology and Modern Construction Technology of Concrete Laser Leveler

  With the continuous improvement of people's requirements for the quality of building construction, the role of laser leveling machines has gradually become more and more obvious. It is indeed a relatively time-saving and labor-saving way to use leveling machines to pave the ground. It saves labor to the greatest extent, and also provides a guarantee for the flatness of the ground construction. We will introduce the relevant knowledge of the laser leveling machine in detail below, please take a look together. First, the leveling principle of the laser leveling machine is: 1. The laser leveling machine relies on the leveling head driven by hydraulic pressure (electricity), cooperates with the laser system and the computer control system to complete the leveling work while automatically leveling. 2. The leveling head is equipped with an integrated scraper, vibrator and leveling plate, which integrates all the work of leveling, leveling, vibrating, compacting and paddle lifting, and completes it at one time. 3. The computer control system automatically adjusts the elevation 10 times per second in real time, and the vibration frequency of the balanced designed vibrator reaches 4000 times per minute. 2. Tips for using laser leveling machine: During the construction of the leveling machine, the concrete sent to the platform needs to be paved and roughly leveled by workers as soon as possible. In addition, the areas around the formwork, walls, columns, trenches, equipment foundations, floor drains, or surrounding equipment that cannot be leveled require manual cooperation for local leveling, and generally 3-4 workers are required to cooperate with the construction.   3. Other matters needing attention: In order to ensure the flatness of the ground, the slump of the concrete sent to the platform needs to be consistent each time to ensure that the concrete feeding speed reaches 40 cubic meters per hour or above, and the initial setting time of each batch of concrete needs to be consistent to ensure the formwork elevation Accurate, and can not be disturbed during the construction period, the newly constructed concrete floor can not be exposed to sunlight, wind, rain and other environments that are unfavorable to concrete health. No reflective objects. The foundation needs to reach the relevant hardness to ensure that the laser leveling machine does not collapse when working on the ground. The height points of the ground in the factory building need to be evenly distributed, and there should be no error in the levelness.

    As the core equipment of modern floor construction, the upgrade and improvement of supporting facilities and technical support of concrete laser leveling machine directly affects the construction efficiency, project quality and equipment service life. The following elaborates on the specific path from the two dimensions of supporting facilities upgrade and technical support improvement: The supporting facilities need to be carried out around the three goals of "maximizing equipment efficiency", "full coverage of construction scenarios" and "improving operation safety", including: Laser system upgrade: The accuracy of traditional laser transmitters is mostly ±3mm/10m, which can be upgraded to high-precision green laser system (accuracy up to ±1.5mm/10m), and add "anti-interference module" (such as filtering technology) to reduce the impact of strong light and electromagnetic environment on the signal; at the same time, it integrates multi-region laser control technology to support multi-machine collaboration during large-area construction to avoid laser signal conflicts. Drive and leveling mechanism optimization: The drive wheel adopts wear-resistant rubber composite material (such as adding ceramic particles) to improve the grip and wear resistance on rough ground; the leveling scraper is upgraded to adjustable alloy material, which supports 0-5° angle fine-tuning to meet the leveling needs of concrete with different slumps (such as dry hard and fluid concrete). Power system adaptation: For indoor scenes with high environmental protection requirements, electric laser leveling machine is developed, equipped with high-capacity lithium battery (8-10 hours of battery life) and fast charging pile (full in 2 hours); large-scale outdoor projects can be upgraded to hybrid power system (diesel + motor), realizing low-speed leveling electricity and high-speed mobile oil, reducing fuel consumption by more than 30%. Material conveying matching: With automatic concrete spreader (such as telescopic spiral spreader), through the linkage of sensors and leveling machine, the integrated process of "concrete conveying-paving-leveling" is realized to reduce the time loss of manual spreading; for narrow spaces (such as around elevator shafts), small auxiliary leveling accessories (such as foldable leveling heads) are developed to adapt to the main equipment to complete the corner construction. Environmental monitoring and adaptation equipment: Add temperature and humidity sensors and concrete initial setting time detector to monitor the construction environment in real time (such as high temperature in summer and low temperature in winter), and automatically adjust the leveling speed through the equipment control system (such as 20% faster at high temperature to avoid premature solidification of concrete); matching dust and noise reduction devices (such as silent engine + high-efficiency filter) to meet the environmental protection standards of indoor construction (noise ≤70dB). Intelligent safety protection: 360° millimeter wave radar and infrared human body sensing device are installed. When the operator or obstacle enters the 1.5-meter range, the equipment automatically slows down and issues an audible and visual alarm; the cab is upgraded to a rollover protection (ROPS) structure, equipped with a suspended seat and seat belt warning system to reduce the risk of injury in the event of an accidental collision. Lightweight and modular design: The fuselage adopts a high-strength aluminum alloy frame (20% lighter than traditional steel structure), with quick-detachable components (such as laser receivers, scrapers), which are easy to transport and repair; for small construction teams, a portable laser leveling machine (weight ≤500kg) is developed, equipped with a small trailer to improve transfer flexibility. Technical support needs to shift from "passive response" to "active service" and build a "full life cycle service chain", including: Remote monitoring and fault warning: Install Internet of Things (IoT) module on the equipment to collect operation data (such as engine speed, laser system status, battery power, etc.) in real time, analyze the health of the equipment through the cloud platform (such as management system based on Alibaba Cloud/Huawei Cloud), warn of potential faults in advance (such as motor overheating, laser calibration deviation), and push maintenance solutions to the user's mobile phone to reduce downtime. Digital construction guidance: Develop a construction parameter database, and preset the "optimal leveling parameters" (such as walking speed 2-5m/min, vibration frequency 3000-5000 times/minute) based on the project type (such as workshop floor, parking lot), concrete grade (C20-C50), and thickness (50-300mm). Novices can call parameters through the device touch screen to reduce the difficulty of operation; supporting AR real-scene guidance system, scan the construction area through the camera, superimpose the virtual image of the laser reference line and leveling trajectory, and assist operators in precise control. Hierarchical training system: For operators, carry out "theory + practice" training (such as laser principle, troubleshooting), and issue operation certificates after passing the assessment; for maintenance personnel, provide "core component maintenance certification courses" (such as laser transmitter calibration, motor maintenance), and regularly organize manufacturer technical exchange meetings to share maintenance skills for new models of equipment. Construction of localized service outlets: Set up regional service centers in key areas (such as the Yangtze River Delta and the Pearl River Delta), equipped with special maintenance vehicles and spare parts warehouses (reserving vulnerable parts such as laser heads and sensors), and promise "2-hour response within 200 kilometers, 4-hour on-site maintenance"; for remote areas, through the "remote video guidance + spare parts express" mode, ensure that basic faults are resolved within 48 hours. Special scenario adaptation technology: For sloped floors (such as parking lot ramps), develop a "slope adaptive system" to adjust the leveling benchmark in real time through the inclination sensor to ensure that the slope error is ≤0.5%; for ultra-large floor areas (such as storage and logistics parks), provide a "multi-machine collaborative management system" to support 1 main control device to monitor the construction progress of 5-8 leveling machines, and achieve an overall flatness error of ≤2mm/2m. Second-hand equipment remanufacturing support: Provide "refurbishment and upgrade services" for old equipment (such as replacing laser systems, upgrading control systems), and issue performance test reports to extend the service life of equipment (usually 3-5 years), and reduce the cost of replacement for users. 1. Industry-university-research cooperation: Cooperate with universities (such as construction machinery majors) and scientific research institutions to develop new materials (such as wear-resistant scraper alloys) and intelligent algorithms (such as multi-machine collaborative control) to maintain technological leadership. 2. User feedback mechanism: Collect user usage data through the equipment Internet of Things system, regularly investigate construction pain points (such as long maintenance cycles and complex operations), and optimize products and services in a targeted manner. 3. Policy and standard adaptation: Pay attention to industry standards (such as "Technical Conditions for Concrete Laser Leveling Machines") and environmental protection policies, and develop equipment that meets new regulations in advance (such as power systems that meet the National IV emission standards) to avoid policy risks. Through the above measures, the supporting facilities of the concrete laser leveling machine can achieve "higher precision, stronger adaptability, greater safety and durability", and the technical support can achieve "fewer faults, quick start-up and timely service", ultimately helping users improve construction efficiency by more than 30%, and the floor flatness qualification rate will be increased from 85% to more than 95%.     Click the below to jump immediately!!!
