How to reduce the construction cost of concrete laser leveling machine?

  In order to ensure the construction quality of concrete floor, more and more construction units now choose to use precision laser leveling machines to lay concrete floor. However, in the actual construction process, due to the inadequate cooperation of some enterprises in construction, or not strictly following the regulations to operate correctly, the quality of concrete floor construction is sometimes poor. In order to avoid such a situation from happening again, our company has made a detailed description of some matters related to the construction cooperation during the construction of the laser leveling machine. We hope that the relevant construction personnel will keep it in mind. ❖Wall line laying and leveling: Since the laser leveling machine cannot touch the wall, manual leveling is required within 200mm from the wall, so it is necessary to lay out the line as a reference for manual leveling. At the same time, set 2 to 3 leveling base points (ground design elevation, i.e. ±0.0) that are not disturbed during the construction period for the laser leveling machine to use at one time, and require good mutual visibility. Leveling point accuracy ±1mm. ❖Set templates (steel templates, the position is determined according to design requirements) around the columns to form separation seams. The elevation of the top surface of the template should be controlled within +0mm and -2mm to avoid affecting the flatness of the joints. ❖Installing construction joint formwork: Install the construction joint template along the range to be poured on the day (steel template is recommended), and the template should reserve holes with a spacing of 300mm for the insertion of the force transmission rod. The elevation of the top surface of the template should be controlled within +0mm and -2mm to avoid large deviations in the flatness of the joints of different bins.   ❖Laser transmitter installation: It is planned to be installed on the column. The specific location should be set at a better location according to the amount of paving on the day. If it cannot be installed on the column, it should be installed on a special tripod.   ❖In order to ensure the quality of concrete floor paving, each group needs to arrange 10 to 12 workers to cooperate to flatten the surface of the concrete spread on the ground so that the pile is slightly higher than the design elevation (about 20 to 30mm). At the same time, for the parts near the wall, exposed pipelines and the surrounding of the formwork, two workers are arranged to manually smooth the concrete material about 20~30cm away from the wall (formwork) (using a 2m scraper with an iron trowel). The workers responsible for smoothing the edges must be trained and skilled plasterers. These workers must obey the command and follow the arrangement to ensure the quality of construction.   ❖ Since the thickness of the concrete reaches 200mm, and because of the installation of steel mesh, in order to ensure the compaction of the concrete, this project needs to arrange a vibrating rod to cooperate with the vibration. At the same time, in order to ensure that the protective layer of the steel mesh reaches the design requirement of thickness (70mm), it is necessary to arrange for manual lifting of the steel mesh and pad the support block in the range to be paved in advance.   ❖ The width of the concrete material paved on the platform each time is required to be no more than 5m, and the length is based on the formwork boundary. The construction direction is from left to right (along the short side direction) and from front to back (along the long side direction). The recommended daily paving volume is 1200~1500㎡. Calculated based on 12 hours of working time per day, the feed rate is required to be 30 to 40m³.   ❖Others: To ensure the flatness of the ground, special attention should be paid during the construction of the laser leveling machine: the slump of the concrete delivered to the platform each time must be consistent; the concrete feed rate must reach 40m. per hour or more, and the initial setting time of each batch of concrete must be consistent; the template elevation must be accurate and cannot be disturbed during construction; environmental coordination. The newly constructed concrete floor cannot be exposed to sunlight, wind, rain and other environments that are unfavorable to the curing of concrete.   Special reminder: In order to make the laser leveling machine give full play to its inherent functions and ensure the construction quality and efficiency of the concrete floor, in addition to mastering the above-mentioned construction coordination precautions, there are many details that need to be paid attention to. Please look forward to the subsequent updates and sharing of this site.

In what cases does the concrete laser leveling machine need to be adjusted or suspended? As a highly efficient modern construction equipment, the concrete laser leveling machine plays an important role in the construction of concrete floors with its precise leveling ability and high operating efficiency. However, in the actual construction process, due to the influence of various factors, it is sometimes necessary to adjust or suspend the construction of the concrete laser leveling machine. This article will elaborate on the specific circumstances in which the concrete laser leveling machine needs to be adjusted or suspended from the aspects of unsuitable environmental conditions, mechanical equipment failure, safety considerations for construction personnel, insufficient or abnormal material supply, changes in construction quality requirements, substandard ground conditions, climate abruptness or natural disasters, and updates or requirements of regulations and standards. 1. Unsuitable environmental conditions Environmental conditions are one of the key factors affecting the normal operation of the concrete laser leveling machine. In the following cases, it is necessary to consider adjusting or suspending construction: First, when the wind force at the construction site is too strong, the concrete surface is easily affected by the wind and causes drying and cracking. Therefore, when the wind force reaches a certain level, the construction should be suspended and the work should be continued after the wind force weakens. Secondly, temperature and humidity are also important factors affecting concrete construction. In high or low temperature environments, the setting time and strength of concrete will change, which may lead to poor leveling effect or other problems. Similarly, too high or too low temperature will also have a negative impact on the construction quality of concrete. Therefore, under unsuitable temperature and humidity conditions, it is necessary to adjust the mix ratio of concrete or suspend construction. 2. Mechanical equipment failure As a mechanical equipment, the concrete laser leveling machine may fail or abnormally during long-term use. The following are some situations that require special attention: First, when the laser transmitter or receiver of the laser leveling machine fails, it will affect the leveling accuracy and effect. At this time, the construction should be stopped immediately and the equipment should be repaired or replaced. Secondly, when the power system, transmission system or control system of the leveling machine fails, it may also cause the equipment to fail to work properly or the leveling effect is poor. In this case, it is also necessary to suspend construction and troubleshoot and repair the fault. 3. Safety considerations for construction personnel Safety is always the primary consideration during the construction process. In the following cases, in order to ensure the safety of construction workers, it is necessary to adjust or suspend the construction of the concrete laser leveling machine: First, when there are safety hazards or accident risks at the construction site, such as falling objects from high altitudes, exposed electrical lines, etc., the construction should be suspended immediately, and the work should be continued after the safety hazards are eliminated. Secondly, the physical condition of the construction workers is also an important factor affecting construction safety. When the construction workers are tired, unwell or make operating errors, the work plan should be adjusted in time or replacement personnel should be arranged to ensure construction safety and quality. 4. Insufficient or abnormal material supply During the construction of the concrete laser leveling machine, the quality and supply of concrete materials are directly related to the leveling effect and construction progress. The following are some situations that need attention: First, when the supply of concrete materials is insufficient, it will lead to construction interruption or delay in progress. In this case, it is necessary to adjust the construction plan in time, increase material reserves or adjust the source of materials. Secondly, if there are quality problems with the concrete materials, such as abnormal setting time and substandard strength, it will have a negative impact on the leveling effect. At this time, the construction should be suspended, and the quality of the concrete materials should be inspected and adjusted. 5. Changes in construction quality requirements During the construction process, the construction quality is sometimes adjusted or changed according to the actual situation or the requirements of the owner. In this case, the concrete laser leveling machine needs to be adjusted accordingly or the construction needs to be suspended. For example, when the owner's requirements for the flatness or levelness of the ground change, the parameters of the leveling machine need to be reset or the leveling process needs to be adjusted. Similarly, if the ground needs to be treated specially or the construction process needs to be improved, the construction needs to be suspended and the relevant measures need to be implemented before continuing the operation. 6. The ground conditions do not meet the standard Ground conditions are the basis for the construction of concrete laser leveling machines. When the ground conditions do not meet the construction requirements, it will affect the leveling effect and construction progress. The following are some common situations. First, when there are unevenness, cracks or debris on the ground, pretreatment or cleaning work needs to be carried out first to ensure that the ground is flat and clean. If the pretreatment work is not completed or the effect is not ideal, the construction should be suspended and the ground conditions should be continued after the requirements are met. Secondly, when the humidity or temperature of the ground does not meet the construction requirements, it will also affect the leveling effect. In this case, corresponding measures need to be taken to adjust the ground conditions, such as increasing ventilation, heating or cooling, etc. 7. Climate change or natural disasters Climate change or natural disasters are factors that cannot be predicted and avoided during the construction process. In the following cases, the construction of the concrete laser leveling machine needs to be suspended immediately: First, when encountering sudden severe weather such as strong winds, heavy rains, thunder and lightning, in order to ensure the safety of construction workers and the stability of equipment, construction should be stopped immediately and corresponding protective measures should be taken. Secondly, when natural disasters such as earthquakes and floods occur, priority should be given to personnel safety, all construction activities should be suspended, and evaluation and resumption of work should be carried out after the disaster has passed. 8. Updates or requirements of regulations and standards With the continuous updating and improvement of regulations and standards in the construction industry, it is sometimes necessary to adjust or suspend the construction of the concrete laser leveling machine. For example, when new safety regulations or environmental protection requirements are introduced, it may be necessary to update and improve the safety measures or environmental protection measures in the construction process. In this case, it is necessary to suspend construction, train and educate relevant personnel, and ensure that the construction meets the requirements of new regulations and standards. In summary, there are many situations in which the concrete laser leveling machine needs to be adjusted or suspended during construction. In order to ensure the safety, quality and efficiency of construction, it is necessary to pay close attention to the changes in various factors during the construction process and take corresponding measures in a timely manner according to the actual situation. At the same time, it is also necessary to strengthen the training and education of construction personnel, improve their professional skills and safety awareness, and ensure the smooth progress of the construction process. 9. Equipment maintenance cycle As a mechanical equipment, the normal operation of the concrete laser leveling machine is inseparable from regular maintenance. When the equipment reaches the predetermined maintenance cycle, it is necessary to suspend construction and conduct comprehensive inspection, cleaning and lubrication of the equipment. This not only ensures the normal operation of the equipment and prolongs its service life, but also avoids construction interruptions and quality problems caused by equipment failure. During the maintenance process, attention should be paid to the vulnerable parts and key components of the equipment, such as laser transmitters, receivers, transmission systems, hydraulic systems, etc., and parts with severe dry wear or damage should be replaced or repaired in time. At the same time, dust and debris on the surface of the equipment should be cleaned to keep the equipment clean and beautiful. 10. Construction plan adjustment During the construction process, sometimes the construction plan needs to be adjusted due to various reasons. For example, when the owner puts forward new requirements or design changes, the construction plan needs to be re-formulated. In addition, when the construction progress is delayed due to external factors, the construction plan also needs to be adjusted to ensure that the project is completed on time. In this case, it is necessary to suspend the construction of the concrete laser leveling machine, communicate and coordinate with relevant personnel, re-formulate the construction plan and adjust the use arrangement of the equipment. Through reasonable adjustment of the construction plan, the smooth progress and timely completion of the project can be ensured. In summary, the concrete laser leveling machine needs to consider adjustment or suspension of construction in the case of unsuitable environmental conditions, mechanical equipment failure, safety considerations for construction personnel, insufficient or abnormal material supply, changes in construction quality requirements, ground conditions that do not meet standards, climate changes or natural disasters, regulatory standards updates or requirements, equipment maintenance cycles, and construction plan adjustments. In the actual construction process, we should pay close attention to the changes in these factors and take corresponding measures according to the actual situation to ensure the safety, quality and efficiency of the construction. At the same time, we should also strengthen the training and education of construction personnel, improve their professional skills and safety awareness, and provide strong guarantees for the smooth progress of the project. Because the concrete laser leveling machine involves complex operation and maintenance, the specific situation in the actual construction process may be more complicated. Therefore, it is recommended to keep in close contact with equipment manufacturers, construction units and relevant experts in the actual construction process to consult and solve problems encountered in the construction in a timely manner. Through continuous practice and experience accumulation, we will continuously improve the application level of concrete laser leveling machines in construction. Please note that the above content is a summary based on existing knowledge and experience, and does not represent all possible situations and solutions. In the actual construction process, it is necessary to make judgments and decisions based on the specific situation. At the same time, with the continuous advancement of technology and the continuous development of the industry, the application and maintenance of concrete laser leveling machines may also have new changes and requirements. Therefore, it is recommended that relevant personnel continue to learn and pay attention to industry trends in order to adapt to and master new technologies and methods in a timely manner.
