Which one is better in terms of construction safety between concrete laser levelings and pavers?

What are the advantages of laser leveling machine? The laser leveling machine is developed according to the increasing demand for ground quality such as strength, flatness, levelness, etc. of modern industrial plants, large shopping malls, warehouses and other large-area cement concrete floors. Not only is it fast and compact, it saves labor input to a great extent and saves economic costs in disguise. Advantages of laser leveling technology:   01 Higher construction quality – the ground elevation and flatness of laser-level precision can be achieved. The floor elevation is automatically controlled by laser and computer, and the leveling unit is adjusted in real time through a two-way hydraulic cylinder (10 times per second), ensuring Precise leveling. 02 The density of concrete is increased by more than 20%, and the strength of concrete is improved, and it is suitable for dry hard concrete, fiber concrete and large aggregate concrete. 03 The laser emitter is arranged independently. The floor construction can be paved in a large area and can ensure the consistency of the ground elevation. The elevation is not controlled by the formwork, and there will be no cumulative error. 04 Compared with the traditional method, the construction joints of the floor can be greatly reduced, and the construction without separate warehouse joints can be achieved. The post-maintenance cost of the ground and the use of templates are also greatly reduced. Due to maintenance and formwork support, the sub-storage joints on the large-area concrete floor will have defects such as damage along the joints. These problems can be avoided by using laser leveling and joint cutting technology.   05 The integrity of the ground is better – it is very easy to achieve large-area overall paving. On the one hand, this overall paving technology can avoid problems such as easy hollowing and cracking caused by layered pouring of the floor, and on the other hand, it can reduce A large number of construction joints make the integrity of the ground better. This is not easy to do with other construction techniques. 06 The vibrating system of the laser leveling machine has a vibrating frequency of 3000 times per minute, which can avoid irregular cracking and other ills caused by uneven stress caused by uneven vibrating. 07 The construction speed is faster – the work efficiency is increased by 100-300% (200-400 square meters of paving work can be completed per hour, and an average of 1500-4000 square meters can be completed per day), and labor is reduced by more than 30%, especially suitable for Projects with tight construction schedule, large paving area and high quality requirements. 08  Save the cost of formwork and support formwork. The leveled cement concrete floor paved by the laser leveling machine is much better than the ground paved by conventional methods-the ground flatness and levelness are increased by more than 3 times, and the compactness and strength are increased by more than 20%. At the same time, it can also improve work efficiency by more than 50%, and save about 35% of labor. In addition, it can easily place high-strength concrete, low-slump concrete and fiber cement. Its laser system is equipped with a variety of automatic control components to monitor the elevation of the leveling head at a frequency of 10 times per second in real time to ensure that the levelness and levelness of the ground being paved are effectively controlled. At the same time, the vibrating frequency of its powerful vibrator reaches 3000 times/min, which ensures that the concrete is vibrated and compacted, so that the entire paved concrete matrix is homogeneous and dense.

  As far as the concrete structure of shale gas platform is concerned, its construction requirements are generally relatively high, and the construction period is relatively long. With the continuous expansion of shale gas drilling platforms, the requirements for drilling rig foundation and platform flatness are constantly raised, and the drawbacks of traditional construction methods are gradually emerging. In order to reduce the labor intensity and improve the flatness of concrete, the application of laser levelling machine in shale gas platform construction has gradually become an inevitable trend. The following is a brief analysis of the specific application of laser leveling machine in shale gas platforms. 1. Analysis of shale gas platform construction status With the continuous acceleration of natural gas development speed, shale gas development gradually to the factory development, the platform area is also expanding, the drilling depth is also increasing, and the requirements for the flatness and construction cycle of the concrete floor are becoming higher and higher. The conventional construction method is to divide the warehouse according to the working width of the vibratory beam 6-7m, divide the whole site into 7-13 pieces in the width direction, support the mold or set up the guide rail on both sides of each piece, pour concrete and smooth the vibratory beam, such method needs to set up the template or adjust the elevation of the guide rail many times. Within the working range of the vibratory beam, the place where the concrete is not hollow and not full cannot vibrate, and small pit functions are more likely to be formed by bleeding and sinking during the later maintenance. Water accumulation occurs in rainy days after the completion of the site, which seriously affects the placement and production and use of shale gas production and transportation equipment in the later stage. Therefore, the conventional method can not meet the requirements of the flatness of the shale gas platform. 2. The feasibility of the application of laser leveling machine ▶ The leveling machine is small in size, light in weight, not high in road capacity, convenient and fast in transportation; ▶ The leveling machine has high degree of automation, low failure rate, simple operation and easy to learn, and low requirements for operators; ▶ The leveling machine has simple structure, low procurement cost, low use cost, and little loss due to weather and other reasons; ▶ The single leveling width of the laser leveling machine can reach 2~3m, the paving speed can reach 4~5m/min, the area of 500 square meters can be completed per hour, and the area of 4000 square meters can be completed every day. It can be seen that the construction speed is fast, and the efficiency is more than 3 times that of the conventional construction method, especially suitable for the shale gas platform construction period is high. Concrete surface construction with simple surface shape and large working surface; The laser leveling machine provides laser signal through a fixed transmitter, which can completely cover the whole scene. The receiver receives the signal in time, and the computer automatically calculates the design elevation according to the current position of the leveling machine, and issues adjustment instructions to the whole plate up to 10 times per second, eliminating the influence of uneven field base and greatly improving the smoothness of the concrete. Compared with the ground constructed by the laser leveling machine and the conventional method, 22 points were detected (one point every 5mx4m), and the average flatness was 1.3mm and 4.1mm, respectively. It can be seen that the leveling quality of the laser leveling machine is more than 3 times that of the conventional method. ▶ Due to the good platform visibility conditions, there is no need to change the position of the laser transmitter during the construction process of the laser levelling machine, which can reduce unnecessary processes and reduce errors caused by operational errors. In the construction process of concrete, it is not necessary to separate the bin support mold, only at the edge of the site support mold can reduce the support modulus of more than 74%. After leveling, the addition of a single disc hand-held polishing machine, double disc driving polishing machine and cutting machine can make the heavy manual labor into mechanical paving, vibrating, leveling, pulp lifting, plastering, which can reduce the operator by 30% compared with the conventional construction method, and save 2 to 3 yuan /㎡ than the conventional process. In summary, the laser levelling machine has fast speed, high efficiency and obvious economic benefits, which is suitable for the characteristics of shale gas platform, and it is very necessary and feasible to construct concrete in large areas in mountainous areas. At present, many pilot application results have confirmed that the use of laser levelling machine is not only feasible but also very necessary in the large-scale concrete construction of shale gas platform. On the one hand, the application of laser levelling machine can improve the flatness of the platform, on the other hand, it can also improve the construction efficiency, shorten the construction period and reduce the cost, compared with the conventional construction method, the benefits brought by this construction method are beyond doubt.
