Four reasons for you to choose laser self-leveling machine!

  – Applicable situations: Applicable to situations where there are small bulges or unevenness in the concrete pavement, the height of the bulge is generally within a few millimeters, and the unevenness is relatively mild. – Operation method: Use a pavement grinder to grind the uneven parts, and grind off the raised parts to make the pavement flat. When grinding, pay attention to controlling the depth and range of grinding to avoid excessive grinding causing the pavement to become thinner or new unevenness. After grinding, clean up the debris and dust on the pavement in time.   – Applicable situations: Applicable to situations where there are shallow potholes or local depressions on the pavement, the depth is usually less than 2-3 cm, and the area is not large. – Operation method: First clean the potholes and remove debris, dust and loose concrete fragments. Then use cement mortar or special pavement repair materials with the same or higher strength grade as the pavement concrete to fill them. When filling, the material should be fully compacted and smoothed to ensure that the surface after filling is consistent with the surrounding road surface. In order to ensure the adhesion between the repair material and the original road surface, a layer of interface agent can be applied to the surface of the pothole before filling.   – Applicable conditions: When the road surface unevenness is more obvious, the depth of the potholes or depressions is about 3-5 cm, and the area is large, the thin layer repair method can be used. – Operation method: First, cut the area to be repaired into a regular shape. The depth is determined according to the degree of unevenness, generally about 3-5 cm. Then clean up the loose concrete in the cut area and treat the base appropriately, such as compaction, cleaning, etc. Then lay a thin layer of repair material that matches the performance of the original road concrete, such as polymer-modified concrete or high-performance repair mortar. When laying, use tools such as flat vibrators or trowels to vibrate and compact the materials, smooth them, and ensure that the repair layer is tightly combined with the original road surface and the surface flatness meets the requirements.   – Applicable situations: Applicable to large areas with poor road flatness, serious unevenness, multiple potholes of varying depths, wavy unevenness, etc. – Operation method: Use a road milling machine to mill off the uneven surface of the road. The milling depth is generally about 5-10 cm, and the specific depth is determined according to the actual situation of the road surface. After milling, clean up the debris and dust, inspect and treat the base layer, and repair and compact any damaged or loose parts. Then re-pave the concrete road surface according to the design requirements, including paving, vibration, troweling and other processes to ensure that the flatness of the newly laid concrete road surface meets the standard. After the concrete is poured, it should be maintained in time to prevent quality problems such as cracks.   – Applicable situations: When the concrete pavement is severely broken, sunken or uneven over a large area, and the base is also severely damaged, partial plate replacement is required. – Operation method: First determine the range of the plates that need to be replaced, use a cutting machine to cut the plates neatly around, then remove the broken concrete plates, and clean up the debris and loose materials on the base. Reinforce the base, such as using compaction, replacement and other methods to ensure that the bearing capacity and stability of the base meet the requirements. Then re-pour the concrete plates according to the design requirements, including installing the formwork, tying steel bars (if required), pouring concrete, vibrating and compacting, and smoothing. After pouring, strict maintenance must be carried out, and traffic will be opened after the concrete reaches the design strength.   – Applicable situations: If the overall flatness of the concrete pavement is extremely poor, and there are large-scale defects such as severe cracks, potholes, and subsidence, and after evaluation, it is believed that the repair can no longer meet the use requirements, or the repair cost is too high, overall renovation can be considered. – Operation method: First, the original pavement should be demolished, the concrete pavement should be crushed and transported away, and the base layer should be thoroughly inspected and treated. If there are weak soil layers or poor geological conditions, corresponding treatments should be carried out, such as replacement and reinforcement. Then, according to the design plan, the pavement structure should be re-laid, including the base layer, subbase layer, surface layer, etc., and the construction should be carried out in accordance with the construction specifications, and the thickness, compaction and flatness of each layer should be strictly controlled. During the construction process, quality inspection and control should be strengthened to ensure that the performance indicators of the new pavement meet the design requirements. The pavement after overall renovation needs to be maintained and debugged for a period of time. After all indicators are stable, it can be officially opened to traffic.     ARMOUR JOINT CONCRETE LASER LEVELING MACHINE LIGHT TOWER STEEL FIBER TRACKED MINI DUMPER POWER TROWEL  

  – Tools and methods: Use a 2-meter ruler and a feeler gauge for measurement. Place the 2-meter ruler on the concrete surface so that it fits tightly against the ground, and then use the feeler gauge to measure the maximum gap between the ruler and the ground. For general industrial and civil building floors, the allowable flatness deviation is usually within 4-5 mm; for places with high precision requirements, such as electronic chip production workshops, precision instrument laboratories, etc., the flatness deviation requirement may be within 2-3 mm. If the measured gap is within the specified range, it means that the compaction effect of the trowel meets the quality standards in terms of flatness. – Visual inspection to assist judgment: In addition to tool measurement, it is also important to observe whether the ground has obvious waves, potholes or bulges by naked eyes. Stand at a certain distance (such as 5-10 meters) to observe the overall effect of the ground to see whether the light is reflected evenly on the ground. If the ground reflects light evenly without obvious changes in light and shadow, it usually means that the ground is relatively flat and the compaction effect is good. – Rebound hammer test: Use a rebound hammer to test the concrete surface. The rebound hammer hits the concrete surface and infers the strength of the concrete based on the rebound value, which indirectly reflects the density. During the test, multiple test points should be selected on the concrete surface (generally no less than 3 points per 10 square meters) to calculate the average rebound value. Concrete of different strength grades has a corresponding standard range of rebound values. For example, the rebound value of C30 concrete is generally between 34 and 46. If the rebound value obtained by the test is within the standard range of concrete of the corresponding strength grade, it means that the concrete density is high and the compaction effect of the trowel is good. – Core sampling analysis: In some cases with extremely high quality requirements or disputes, the core sampling method can be used. Use professional core drilling equipment to take out core samples with a diameter of usually 100-150 mm in the concrete structure. Observe the appearance of the core sample, which should be uniform in texture and without obvious pores and stratification. Then send the core sample to the laboratory for compressive strength testing and porosity analysis. The compressive strength meets the design requirements and the porosity is low (generally no more than 5% – 8%, depending on the specific project requirements), indicating that the density of the concrete meets the quality standards and the compaction effect of the trowel machine is qualified. – Visual observation: Carefully observe the trowel traces on the concrete surface. The trowel traces should be uniform and continuous, without obvious depth or interruption. If the trowel traces are uniform, it means that the pressure applied by the trowel machine to the ground during work is uniform and the compaction effect is good. For example, after the construction of a large area of ​​parking lot floor, the trowel traces on the entire floor should show a consistent texture, without local roughness or over-troweled areas. – Touch inspection: Touch the concrete surface with your hand to feel whether its smoothness and hardness are uniform. If the surface feels consistent and there is no local softness or over-hardness, it can also indicate to a certain extent that the compaction effect is uniform and meets the quality standards. – Test block test under the same curing conditions: During the concrete construction process, make test blocks that are cured under the same conditions as the actual construction concrete. At the specified age (such as 7 days, 28 days), the compressive strength of the test block is tested, and the test results are compared with the design strength grade. If the strength of the test block can reach or exceed the design strength according to the expected growth curve, it means that the compaction operation of the trowel machine has no adverse effect on the strength of the concrete, and the compaction effect meets the quality standards. – On-site rebound-core drilling comprehensive method evaluation: Combined with the rebound hammer test and core drilling sampling, the strength of the on-site concrete structure is comprehensively evaluated. The rebound hammer is used to quickly screen out areas that may be insufficient in strength, and then core drilling sampling is performed on these areas for verification. If the overall strength of the on-site concrete meets the design requirements, and the strength distribution in different areas is relatively uniform, it means that the compaction effect of the trowel machine is good and meets the quality standards.

To optimize the construction effect of the concrete laser leveling machine, the laser receiver can be adjusted by the following methods: 1. Calibrate the laser receiver: Before construction, calibrate the laser receiver to ensure it is in the correct position and angle. Through calibration, the initial error of the laser receiver can be eliminated and the accuracy and stability of construction can be improved. 2. Adjust the sensitivity of the laser receiver: According to the construction environment and conditions, appropriately adjust the sensitivity of the laser receiver. In an environment with more interference factors, you can choose to increase the sensitivity of the laser receiver to better capture the laser signal. In a quieter environment, the sensitivity can be appropriately reduced to reduce false triggering. 3. Adjust the receiving range of the laser receiver: According to the construction scope and speed, appropriately adjust the receiving range of the laser receiver. In situations where rapid construction is required, there is an option to expand the laser receiver's reception range to cover a wider area. In situations where refined construction is required, the receiving range can be appropriately narrowed to improve the accuracy and stability of construction. 4. Regularly clean and maintain the laser receiver: Keeping the laser receiver clean and in good condition is crucial to optimizing construction results. Clean optics and housings regularly and check for damage or contamination. Use appropriate cleaners and tools for cleaning, and ensure that maintenance and upkeep is performed in accordance with the manufacturer's instructions. 5. Adjustment with other equipment: Ensure good cooperation and synchronization between the laser receiver and other related equipment (such as control systems, sensors, etc.). Learn how to adjust the parameters and settings of relevant equipment to achieve the best construction results by communicating with the supplier or manufacturer's technical support team. 6. Record and monitor the adjustment process: During the process of adjusting the laser receiver, it is recommended to record the detailed steps and parameters of each adjustment. This helps track the effects of adjustments and ensures you can quickly return to optimal performance when needed. At the same time, the construction effect is continuously monitored, and the performance and status of the laser receiver are regularly checked to ensure that it continues to provide accurate signals and stable output. In short, through proper calibration, sensitivity adjustment, reception range setting, maintenance and coordination with other equipment, the construction effect of the concrete laser leveling can be significantly optimized. It is recommended to work with an experienced technician or supplier on the actual application to ensure proper adjustment and optimal performance.
