HOW TO MAINTAIN CONCRETE FLOORS IN DIFFERENT SEASONS? -VANSE Machinery The current concrete floor is compacted with a concrete laser leveling machine, and there is almost no error. Concrete technology is becoming more and more important. Concrete has developed from the initial low-strength grade and ordinary concrete to today's high-strength grade and high performance. Sometimes the maintenance of concrete is often ignored in engineering construction, causing the surface of the concrete to shrink. , cracking, peeling and other phenomena, in order to make the concrete floor more sustainable and long-term use, it is necessary to pay special attention to the concrete curing method during construction. Different environments have different maintenance methods: During the high temperature and dry season, the moisture in concrete is easy to lose, so the following measures should be actively taken: 1. Cooling measures must be taken during construction, such as choosing to pour at night to avoid direct sunlight, and adjusting the concrete ratio in time. 2. At the same time, it must be noted that the temperature of the concrete formwork must be cooled, because if the temperature of the formwork is too high, the surface of the concrete will lose moisture quickly after pouring, resulting in defects such as sanding on the concrete surface. The maintenance of concrete in this season requires a lot of water, especially for the parts that are not easy to maintain, such as columns, cover beams, and beam webs, they should be tightly wrapped with geotextiles and sprinkled regularly. The surface of the concrete is always in a humid environment. In the early stage of curing, the concrete surface is sometimes dry and sometimes wet, because the strength of concrete that is sometimes dry and sometimes wet is easy to reduce, and it is easy to produce shrinkage cracks. Therefore, within 7 days of concrete pouring, it is necessary to prevent water evaporation and keep the concrete surface moist. In short, the focus of concrete maintenance in this season is moisturizing. If measures such as moisturizing and cooling are done well, problems such as early setting of concrete, plastic cracks, reduction of concrete strength and durability caused by high temperature will not appear. In the cold season when the temperature is lower than 5°C, the following measures should be taken for the maintenance of concrete: 1. After demoulding, cover and maintain the insulation. 2. The use of steam curing. 3. Improve the thermal insulation performance of the formwork. Most of the steel formwork used in bridge construction has good thermal conductivity and is easy to lose temperature. Therefore, insulation materials such as straw curtains should be wrapped outside the formwork or measures such as thickened formwork and double-layer formwork should be used. 4. Increase the mixing temperature of concrete. First of all, the heating treatment of the mixing water can be considered, and the aggregate can also be considered to be heated. The purpose is to ensure the initial cement hydration temperature and improve the early strength of the concrete. If the maintenance of concrete in the early cold period takes the above measures actively, the concrete will be prevented from freezing due to low temperature. After the concrete is frozen, its hydration will stop. After the temperature rises, although it can continue, the surface of the concrete has changed. Crisp, lose strength, and even larger cracks appear. Therefore, it is necessary to especially strengthen the early insulation and maintenance of concrete, and it must not be frozen before the concrete strength reaches 50% of the design strength.

As a key equipment in modern building construction, the concrete laser leveling machine's leveling effect and quality directly affect the flatness and service life of the concrete floor. In order to ensure the work effect and quality during the leveling process, fine control and operation are required from multiple dimensions. •••▶ Preparation before operation ◀••• 1. Site Assessment: Before starting grading work, conduct a detailed assessment of the construction site. Check the basic condition of the ground, including the pouring quality, flatness, strength, etc. of the concrete. Understanding the condition of the ground will help you choose the appropriate leveling method and parameters. 2. Equipment inspection: Conduct a comprehensive inspection of the concrete laser leveling machine to ensure that the equipment is in good working condition. Check key components such as laser systems, power systems, transmission systems, and control systems to ensure that they can operate normally and provide stable performance. 3. Set parameters: Set appropriate leveling parameters according to construction requirements and ground conditions. This includes adjustments to the laser system, leveling speed, leveling depth, etc. The setting of parameters should take into account the flatness of the ground, construction efficiency and quality requirements. •••▶ Operations during leveling ◀••• 1. Maintain a stable traveling speed: During the leveling process, the operator should maintain a stable traveling speed. Avoid speeds that are too fast or too slow to avoid affecting the leveling effect and quality. A stable travel speed helps ensure uniform force on the ground, reducing unnecessary fluctuations and errors. 2. Adjust the laser system in time: The laser system is the core component of the mixed soil laser leveling machine and provides accurate leveling reference lines. During the leveling process, operators should pay close attention to the status of the laser system and adjust the height and position of the laser line in a timely manner to ensure leveling accuracy and stability. 3. Even distribution and vibration: Before leveling, the concrete should be evenly distributed and vibrated. The fabric should be even and avoid any accumulation or voids. Vibration should be sufficient to improve the compactness and strength of the concrete. 4. Control the leveling depth: The leveling depth is an important factor affecting the leveling effect and quality. Operators should control the leveling depth according to ground conditions and construction requirements. Leveling that is too deep will cause the ground to be too thin, affecting the strength and flatness; leveling that is too shallow will not be able to effectively eliminate uneven ground problems. 5. Pay attention to observation and adjustment: During the leveling process, the operator should always pay attention to the changes in the ground. If problems such as waves, bulges or depressions are found on the ground, leveling parameters should be adjusted in time or other measures should be taken to repair them. •••▶ Quality control after leveling ◀••• 1. Ground inspection: After the leveling work is completed, a comprehensive inspection of the ground should be carried out. Check the flatness, levelness, verticality and other indicators of the ground to ensure that it meets the construction requirements. If problems are found, they should be repaired and adjusted in time. 2. Test block production and testing: According to the construction requirements, test blocks are made and corresponding strength and durability tests are performed. Through the test results of the test blocks, the quality and performance of the concrete during the leveling process can be evaluated. 3. Maintenance: After the leveling work is completed, the concrete laser leveling machine should be cleaned and maintained in a timely manner. This helps extend the life of the equipment and ensures stable performance the next time you work on it. •••▶ People skills and training ◀••• 1. Improve operating skills: Operators should have good operating skills and be able to master the operating essentials of the concrete laser leveling. Through regular training and skill assessment, the skill level of operators can be improved and the stability and accuracy of the leveling process can be ensured. 2. Enhance quality awareness: Operators should fully understand the importance and quality requirements of leveling work. By strengthening quality education and publicity, operators will increase their sensitivity and attention to quality issues, thereby paying more attention to details and quality control in their work. •••▶Coordination with other construction links ◀••• 1. Coordination with the pouring process: The leveling work of the concrete laser leveler is carried out after the concrete is poured. Therefore, coordination with the pouring process is crucial. Pouring should ensure that the concrete is evenly distributed and free of bubbles and voids, providing a good foundation for leveling work. 2. Connection with subsequent maintenance: After the leveling work is completed, subsequent maintenance work needs to be carried out, such as watering, covering, etc. Work closely with the street coordinators in the subsequent maintenance process to ensure that the ground is not damaged during the maintenance process and remains in good condition. •••▶Technical updates and equipment upgrades ◀••• 1. Pay attention to new technologies and equipment: With the advancement of science and technology and the development of the construction industry, new leveling technologies and equipment are constantly emerging. Pay attention to the development of new technologies and new equipment, and timely introduce and apply advanced technologies and equipment that suit your own construction needs, which will help improve the leveling effect and quality. 2. Regularly update and upgrade equipment: As construction equipment, concrete laser levelings may experience performance degradation or technological backwardness as their usage time increases and technology advances. Therefore, regular updates and upgrades of equipment are necessary. By updating and upgrading equipment, the advancement and stability of the equipment can be maintained, and the leveling effect and quality can be improved. In summary, ensuring the working effect and quality of the concrete laser leveling machine during the leveling process requires preparation before operation, operation during the leveling process, quality control after leveling, personnel skills and training, and other construction We will start from various aspects such as coordination of links, technology updates and equipment upgrades.
