How to extend the service life of laser leveling machine

How does a laser leveling work? Do you know the leveling process of laser leveling machine? For how to do a good job in floor engineering, the selection of materials and construction technology are equally important. Laser leveling machine is also the key point that needs to be grasped in the construction process. Industrial plants have high requirements on the flatness of the ground level and surface resistance. Manual construction is difficult to grasp and control, and it is difficult to achieve standardized construction. The following articles are how to construct laser leveling machines and precautions, and how to avoid construction errors. 1 The construction of the floor project needs to be fully prepared. From laying the base and steel mesh – setting the dowel bar – placing the buffer zone – concrete mixing, every step is carefully grasped the details. (1) After the base layer is processed, the equipment of the laser paver is debugged, and the original benchmark point is used as the fixed reference level point; the non-woven fabric is laid, the side formwork is supported, the laser transmitter is erected, and the ground level is introduced into the laser leveling machine according to the original benchmark point. (2) Commercial concrete is used for transporting concrete, and the commercial concrete is transported to the entrance and exit of the garage by tank truck, and then transported to the construction site by a three-wheel dump truck. (3) Scale calibration Use a hand-held laser receiver to check the floor elevation, introduce the elevation into the laser paver, and adjust the reference point (±0.00) on the leveling machine. 2 The concrete mixed in the mixing station is pumped and paved on the gravel base. The paving speed of the laser leveling machine should be appropriate, and the paving can be quickly assisted by manual paving. 3 About 3-4 hours after the concrete is paved by the laser leveler, the best time is when there are no clear footprints after the master. Use a single-disc or double-disc trowel, install a rubbing disc, and rub it repeatedly during the initial setting of the concrete until the concrete slurry is released. Use a single-disc and double-disc trowel, install a smoothing disc, and rub it repeatedly when the concrete bleeds and initially sets until the concrete slurry is released. 4 It is recommended to throw the specified amount of wear-resistant material evenly on the concrete surface just after the grout is broken, and the places that lose water quickly near the formwork, columns, doorways, walls, and pits should be thrown first. Depending on the specific conditions, special materials can be thrown in more than two times. 2/3 of the amount of the first throwing; the remaining 1/3 of the second throwing; the time interval between the two spreading of aggregate should not be too long. 5 After the aggregate is sprinkled once, after the aggregate absorbs the coagulated water, the aggregate is polished and compacted with a trowel, and then the aggregate is sprinkled for the second time, and the compacted aggregate is polished with a trowel. The amount of wear-resistant aggregate is not less than 5kg/㎡. During the grinding and compacting process, a ruler can be used to assist scraping. If it is not smooth, adjust the distribution of aggregates and grind again. The number of grinding times of the laser leveling machine can be operated by construction personnel according to specific conditions. The corners are scraped manually. The front and back grinding directions are criss-crossed, and the flatness is checked with a ruler after the grinding is completed. 6 Depending on the hardening of the concrete, perform at least three trowel operations without discs after the surface has faded. The operation speed and angle of the trowel should be adjusted according to the hardening of the concrete. It is recommended to adjust the angle of the blade at the beginning of each finishing to avoid damage to the floor. 7 After scientifically completing the laser leveling machine construction process, it takes more than 28 days to maintain the floor. After the construction is completed, sprinkle water for maintenance, and lay geotextiles to reduce water evaporation and keep the wear-resistant floor after construction in water. 8 Cut the expansion joints after the concrete has been watered and cured for 24 hours. Because the interval between the wall pillars is about 7 meters, which meets the requirements of the expansion joint gap, the expansion joints are mainly distributed according to the structure of the wall pillars, forming a layout of 7m*7m; the depth is about 6-7cm, and the gap is about 5mm.

To prevent and deal with the malfunctions and problems that occur during the leveling process of the laser leveling machine, you can start from the following aspects: 1. Regular maintenance and upkeep *Daily inspection: After every day's work, conduct a routine inspection on the laser leveling machine to see if each component is normal and whether there are any abnormal sounds or heat. *Regular maintenance: According to the manufacturer's recommendations, perform comprehensive maintenance on the laser leveling machine on a regular basis, including changing the oil, checking the electrical system, cleaning the optical path, etc. 2. Operator training *Operation training: Ensure that operators have received professional training and are familiar with the machine's performance, operating procedures and safety precautions. *Experience exchange: Regularly organize experience exchange meetings between operators to share experience and jointly solve problems encountered 3.Concrete material control *Material testing: Before concrete is paved, its various performance indicators are tested to ensure that it meets the construction requirements. *Mix ratio adjustment: According to the actual situation, fine-tune the concrete mix ratio to adapt to the construction requirements of the laser leveling machine. 4. Consideration of environmental factors *Temperature and humidity: Understand the temperature and humidity conditions of the day before construction to avoid construction in extreme environments. *Dust-proof measures: Take appropriate dust-proof measures to reduce dust on the construction site and protect the optical path system of the laser leveler 5. Emergency treatment of equipment failure *Failure emergency plan: Develop an emergency response plan for laser leveling machine failures, including common failure types, processing methods, backup equipment, etc. *Timely response: Once an equipment failure is discovered, it should be stopped immediately for inspection, handled according to the plan or seek help from professional maintenance personnel. Through the implementation of the above measures, faults and problems that occur during the leveling process of the laser leveling machine can be effectively prevented and dealt with to ensure the smooth progress of the construction. At the same time, it is also necessary to pay attention to new technologies and methods, constantly update maintenance and treatment strategies, and improve the operating efficiency and service life of equipment.

  The construction effect of laser leveling machine will change under different climatic conditions. Here are some specific effects and corresponding adjustment methods: 1. **Temperature change**:   – Under high temperature conditions, the setting speed of concrete is accelerated, and the laser leveling machine needs to adjust the working speed to adapt to the faster setting time. At the same time, attention should be paid to the heat dissipation of the equipment and the moisture retention of the concrete. – Under low temperature conditions, the setting speed of concrete slows down, and measures may need to be taken such as using heating equipment or choosing a concrete formula suitable for low temperature construction. 2. **Humidity effect**:   – High humidity environment may affect the drying speed of concrete. When the laser leveling machine is used for construction, it is necessary to extend the curing time to ensure that the concrete is fully hardened. – Low humidity or windy environment may cause the moisture on the concrete surface to evaporate too quickly. Measures need to be taken to keep the concrete moist, such as covering with wet cloth or increasing the frequency of watering. 3. **Rainfall effect**:   – Rainfall may occur during construction, and rain protection measures, such as temporary shelters, need to be prepared to protect the newly constructed concrete surface from rain erosion. 4. **Influence of wind speed**:   – High wind speed may affect the stability of the laser signal of the laser leveler. It is necessary to consider the impact of wind direction and wind speed on the laser transmitter and receiver, and take corresponding wind protection measures. 5. **Construction process adjustment**:   – Under different climatic conditions, it may be necessary to adjust the construction process, such as the paving speed of concrete, the travel speed of the laser leveler, and the vibration frequency, to ensure the construction quality. 6. **Equipment maintenance**:   – Different climatic conditions have different maintenance requirements for laser levelers. For example, in a humid environment, it is necessary to pay attention to the rust and moisture prevention of the equipment; in a dusty environment, the equipment needs to be cleaned regularly to prevent dust from affecting the performance of the equipment. 7. **Construction plan arrangement**:   – Reasonably arrange the construction plan according to the climatic conditions, avoid construction under extreme climatic conditions, such as avoiding construction in heavy rain or high temperature, to reduce the impact on the construction effect. Through the above adjustments, the laser leveler can maintain the construction effect under different climatic conditions and ensure the construction quality and efficiency.
