Safety measures and emergency treatment methods in concrete structure construction

  – Working principle: The laser concrete leveler uses the laser beam emitted by the laser transmitter as the reference plane, receives the laser signal through the laser receiver, and automatically controls the scraper height of the leveler. During the leveling process, the scraper of the leveler is raised and lowered according to the height of the laser reference plane to accurately level the concrete, which can effectively control the flatness and levelness of the road surface. – Operation points: First, the laser transmitter should be reasonably arranged at the construction site to ensure that the laser beam it emits can cover the entire construction area and is not blocked by obstacles. Then, the operator drives the leveler at a constant speed on the concrete, and the machine will automatically adjust the scraper height according to the laser signal to level the concrete. During the construction process, pay attention to the working status of the laser receiver and the leveling effect of the machine. If there is any abnormality, stop the machine in time for inspection and adjustment. At the same time, for corners that are difficult for the leveler to reach, manual assistance is still required.   – Working principle: The paver evenly distributes concrete on the roadbed through the spiral distributor, and uses the vibrator to compact the concrete, forming a preliminary flat road surface during the process. – Operation points: Before construction, the paver parameters, such as the spiral distributor height, vibration frequency and amplitude, need to be adjusted according to the width and thickness of the road surface. During construction, the paver should be kept moving at a constant speed to ensure that the concrete paving thickness is uniform, thus laying the foundation for subsequent road leveling work.   – Working principle: The vibration beam relies on its own vibration to squeeze and compact the aggregate particles in the concrete, and vibrate the cement mortar on the surface, so as to further level the road surface and improve the density. – Operation points: When using, the vibration beam needs to move slowly along the concrete road surface, and the vibration frequency and walking speed should be reasonably adjusted according to the slump of the concrete and the road surface conditions. For local uneven areas, the vibration beam can be manually assisted to carry out key treatment.   – Working principle: The disc or blade of the trowel squeezes and smears the concrete surface when rotating, making the surface smoother and more compact, and improving the density and wear resistance. – Operation points: The surface should be troweled after the water on the concrete surface is slightly dry, and the appropriate trowel operation speed should be selected according to the coagulation of the concrete. For large-area pavement, a driving trowel can be used to improve efficiency, and narrow areas such as corners can be carefully processed with a hand-held trowel.   – Working principle: Construction workers use wooden trowels, iron trowels and other tools to carefully trim the pavement with experience and feel, and deal with local uneven areas that are difficult for equipment to take care of. – Operation points: Mainly fine-tune the corners of the pavement, around the construction joints, and the traces left by the equipment, requiring construction workers to be skilled and able to accurately judge and deal with uneven areas to achieve higher flatness requirements.  

  ✨Accurate Elevation Control: The concrete laser leveling machine utilizes a laser-controlled leveling system. It takes the plane formed by the rotating laser beam emitted by the laser transmitter as the control reference. As long as the laser transmitter is not disturbed, the elevation of the entire floor can be accurately controlled. This ensures that the error in floor elevation is extremely small, reaching millimeter-level accuracy. In contrast to traditional manual leveling methods that rely on multiple reference points, which are prone to errors, the concrete laser leveling machine only requires 1-2 reference point elevations for the entire floor, reducing errors caused by multiple reference points. ✨Minimal Flatness Error: The laser-controlled leveling system of the machine can continuously and accurately measure and adjust the height of the concrete surface during the leveling process. This results in a much better-controlled flatness of the ground, with the flatness and levelness of the ground being more than three times better than that of traditional manual leveling operations. ✨Large-Area Paving: The concrete laser leveling machine facilitates large-area, one-time integral paving of the floor. It can continuously operate until the completion of the entire floor according to the required block-division construction, effectively avoiding problems such as easy hollowing and cracking caused by the layered pouring of the floor. This is difficult to achieve with traditional construction techniques. ✨Reduced Construction Joints: The large-area integral paving method significantly reduces the number of construction joints. Fewer construction joints mean less potential for damage along the joints due to factors such as wheel loads, which improves the overall integrity of the ground and also helps to reduce subsequent maintenance costs. ✨High-Frequency Vibration and Compaction: During the leveling of concrete, the concrete laser leveling machine operates at a constant speed. The leveling head's vibrating plate is equipped with a high-frequency vibrator that vibrates at 4000 times per minute. This generates uniform high-frequency vibrations, which effectively compact the concrete, making the ground more uniform and dense. The density of the concrete can be increased by more than 20%, which is beneficial for improving the strength and durability of the ground. – The concrete laser leveling machine is suitable for use with various types of concrete, including dry-hard concrete, fiber-reinforced concrete, and large-aggregate concrete. It can meet the construction quality requirements for different types of concrete floors, demonstrating strong adaptability.       Click the below to jump immediately!!!

  If the blade angle is too large, the blade will cut into the concrete surface excessively when the trowel is running, resulting in scratches of varying depths on the concrete surface, making it difficult to form a flat surface. If the blade angle is too small, the contact area between the blade and the concrete surface is too large, and the pressure is insufficient, so that the unevenness of the concrete surface cannot be effectively smoothed, making the concrete surface flatness fail to meet the requirements. When the blade angle is not appropriate, such as a slightly large angle, the blade cannot evenly squeeze and smooth the concrete surface during the troweling process, which will cause uneven distribution of cement slurry on the surface. In some places, the cement slurry is excessively scraped away, and in some places, too much is retained, thereby affecting the surface finish and making the surface look rough and matte. If the angle is too small, the blade will not compact the concrete surface enough, and the pores on the surface cannot be effectively filled and closed, which will also reduce the surface finish of the concrete. Improper blade angle adjustment will cause the trowel to exert uneven force on the concrete surface during operation. If the angle is too large, the scraping force of the blade will be too strong, which will easily leave obvious marks on the concrete surface. In severe cases, excessive scraping may cause micro cracks on the concrete surface. Uneven force caused by inappropriate angles may also cause inconsistent shrinkage in different parts of the concrete surface, which in turn causes surface cracks and affects the durability and aesthetics of the concrete structure. Due to improper blade angles, the compaction degree of the concrete surface is different during the troweling process, which will lead to differences in the density of different areas of the concrete surface. For example, in areas with too large angles, the concrete is over-extended and the surface is too dense, while in areas with smaller angles, the concrete density is insufficient, which makes the strength distribution of the concrete surface uneven, reducing the overall quality and performance of the concrete.
