How can it be judged whether the compaction effect of the concrete power trowel meets the quality standards?

    This is the core component of the laser leveling machine, responsible for generating high-quality laser beams. Its quality directly affects the working effect and stability of the leveling machine.Leak inspection: Carefully inspect the entire hydraulic system, including: This system is responsible for positioning the laser beam to the surface of the object to be measured for scanning and reflection. It is generally composed of rotating mirrors, oscillators, optical devices, etc. Its accuracy and speed have a direct impact on the leveling accuracy of the leveling machine. This is the part that performs leveling actions. It is usually made of wear-resistant materials and can complete paving, scraping, tamping and other actions. Its one-time forming width can reach 2.5 meters (depending on the machine itself, 2.5m, 3m, 4m, etc.). In addition, the rotating auger can discharge materials in forward and reverse directions, and it discharges materials in the forward direction during normal operation. It is mainly used for lifting and angle adjustment of the leveling mechanism. There are two self-aligning spherical bearings at the hinge of the lifting frame. The nut at the adjusting screw rod can adjust the angle of the leveling mechanism to adapt to different concrete. 2 high-pressure double-rod lifting cylinders are used to fix the leveling head and level it up and down. A front guard is installed in front to secure and protect electrical components such as lamps and aviation plugs. Used to fix the laser receiver. During the construction process, the bracket and the receiver cannot be moved at will, otherwise it will affect the leveling accuracy. This stand can be turned upside down during transportation to reduce the overall height. Including high-strength frame, power part, hydraulic system, electrical system, cleaning system, etc. The high-strength overall frame is the main frame of the laser leveling machine and fixes all components. During transportation, the safety lifting lugs on the frame can be used for lifting. The overall frame makes the machine safer and more reliable. In addition, there are also components such as a leveling feedback system.

  – Material inspection: Make sure that the mix ratio of concrete meets the construction requirements. For laser leveling machine construction, the slump of concrete is generally recommended to be between 12 and 18 cm, so that the concrete has good fluidity and is convenient for the leveling machine to operate. For example, in the construction of large factory floors, the slump of concrete should be tested in advance to avoid affecting the leveling effect due to inappropriate slump. – Base treatment: The ground base needs to be solid and flat. If there are uneven areas on the base, the thickness of the concrete will be uneven, affecting the final flatness of the ground. Therefore, before construction, the base should be cleaned and repaired, debris, dust, etc. should be removed, and potholes should be filled.   – Vibration link: After the concrete is laid, before using the laser leveling machine, you can use a vibrating rod for preliminary vibration to make the concrete more compact. But pay attention to the vibration time and depth to avoid excessive vibration causing concrete segregation. During the vibration process, it should be coordinated with the construction sequence of the laser leveling machine. Generally, the leveling operation should be carried out as soon as possible after vibration. – Leveling operation: When the laser leveling machine is used for concrete floor construction, the parameters of the equipment should be adjusted according to the design elevation and slope requirements of the ground. During the construction process, the walking speed of the machine should be uniform, avoiding too fast or too slow. Too fast speed may cause insufficient flatness of the ground, and too slow speed will affect the construction efficiency. At the same time, pay attention to the height and angle of the scraper to ensure that the concrete surface is flat and smooth.   – Moisturizing maintenance: After the concrete is leveled, moisturizing maintenance should be carried out in time. Plastic film, straw mats, etc. can be covered on the surface to prevent the concrete from cracking due to excessive evaporation of water. The maintenance time is generally not less than 7 days. In hot weather or dry environment, the maintenance time should be appropriately extended. – Temperature control: The temperature of asphalt material is crucial to the construction quality. During construction, the temperature of hot-mix asphalt mixture should meet the requirements of construction specifications. Generally, the exit temperature of ordinary asphalt mixture is between 140 and 165℃. If the temperature is too low, the asphalt mixture will become viscous, which is not conducive to the construction of the leveling machine; if the temperature is too high, it will accelerate the aging of asphalt. – Base treatment: Similar to concrete floors, the base of asphalt floors also needs to be solid and flat. At the same time, the base must be kept dry, because if there is moisture in the base, after the asphalt is paved, the evaporation of moisture will cause hollowing and cracking problems in the asphalt pavement.   – Paving uniformity: During the asphalt paving process, the asphalt mixture must be spread evenly. When the laser leveling machine is in operation, pay attention to controlling the pressure of the scraper to avoid excessive pressure that causes excessive extrusion of the asphalt mixture, affecting its density and surface flatness. – Joint treatment: In asphalt floor construction, joint treatment is a key link. When using a laser leveling machine for multi-width paving, the longitudinal joints between the two widths must be handled well. Generally, the hot joint method can be used, that is, a certain width (generally 10-20cm) of the first paved asphalt mixture is left unrolled for the time being, as the reference surface for the later paving part, and then the joint is leveled with a leveler so that the two asphalt pavements can be well connected.   – Compactness inspection: After the asphalt floor construction is completed, the compaction of the ground should be checked. Nuclear density meters and other equipment can be used for testing to ensure that the compaction meets the design requirements. If the compaction is not enough, the asphalt floor will cause rutting and other diseases during use. – Stone selection and processing: Select stones with uniform size specifications and good flatness. Before paving, the back of the stone should be cleaned to remove dust, impurities, etc., and appropriate back coating can be performed to enhance the bonding between the stone and the base. – Base preparation: The base needs to have sufficient strength and stability, and cement mortar is generally used as the base material. The flatness error of the base layer should be controlled within a small range to provide a good foundation for stone laying.   – Laying accuracy: When using a laser leveler to assist in laying stones, the laying height and levelness of the stones should be accurately controlled. Since the stone itself is heavy, the leveler should be careful to avoid collision with the stone during operation to prevent the stone from breaking or shifting. For large-sized stones, multiple people may be required to cooperate in the construction and use the leveler for fine-tuning. – Use of bonding materials: When laying stones, the bonding materials (such as cement mortar or special stone glue) should be applied evenly and the thickness should be moderate. The laser leveler can be used to check the flatness of the stone after laying. For uneven stones, adjustments can be made before the bonding materials solidify.   – Cleaning and protection: After the construction is completed, the stains and bonding material residues on the stone surface should be cleaned in time. And the stone surface can be protected, such as applying protective agents, to prevent the stone from being polluted and eroded, and extend the service life of the stone floor.

  Laser leveling machine is a great helper for leveling machinery in construction, but road construction workers can always feel that after several years of use, the equipment is far from being as flexible and convenient as before. What is the reason? Many users only know the surface, but not the reason, and can only procrastinate, and regret it when they use it next time. During the use of laser leveling machine, due to the different intensity of work, it is very likely to have some minor faults after use. At this time, road construction workers should pay attention to it. After use, they should do some daily maintenance on the machine appropriately, which can extend the service life of the machine equipment. 1. Check the connection and fastening of each component of the laser leveling machine, whether the connecting bolts are loose or broken, and tighten or replace them if necessary. Check for leaks and eliminate leaks in various parts in time. Pay attention to the amount of engine oil, fuel, coolant and hydraulic oil, and add new oil to the oil mark as required. Is there an appropriate amount of grease in the centralized lubrication device? 2. Be careful not to work under the maximum load that the machine can bear, and use the machine to the best of your ability. As a laser leveling machine manager, when designating an operator, the laser leveling machine random data and operation manual should be handed over to the operator so that he can master the mechanical performance and operating procedures normally, and the relevant data should not be withheld at will. 3. Try to ensure the uniform addition and subtraction of the mechanical load, so that the machine is in a relatively gentle load change. Specifically, it is to add and subtract the throttle more evenly to prevent the ups and downs of the engine and working device. 4. There will be a lot of dust and mud on the laser leveling machine after construction. First, wipe the dust on the laser leveling machine clean, and wipe the dirt and oil stains with thin paper or cotton cloth. 5. If the laser signal is lost during the construction of the laser leveling machine, the machine needs to be restarted, and the interval time needs to be more than ten seconds. 6. If there are too many stains, you can soak it in water diluted with neutral detergent with a soft cloth, wring it out and wash it. Wanshi laser leveling machine manufacturers remind everyone to remember not to use volatile oil, thinner, gasoline and other chemicals for cleaning and wiping. Developing good habits of operating the laser leveling machine will be of great help in the construction and storage of the laser leveling machine in the future. This not only improves work efficiency, but also extends the service life of the machine to a certain extent.
