Geogrid reinforcement technology widens roadbed
The main points of reinforcement technology before the roadbed is widened and the geogrid is laid. Before laying, the polyester geogrid factory price should be checked for quality, and all performance parameters can be used after reaching the construction standards to eliminate the influence of material quality problems.
Then, according to the construction specifications and design standards, organize on-site measurement and lofting to remove all the debris on the working face. After leveling, the geogrid can be laid as required. Attention should be paid to the position of the geogrid when laying. The distance between the geogrid and the boundary should be between 8 and 13 cm. For the geogrid that has been bonded, the distance between the geogrid produced by uniaxial plastic geogrid manufacturers and the boundary shall not exceed 13 cm. During the entire laying process, the flatness of the base must be guaranteed to avoid sharp protrusions.
Laying must be completed at one time, especially to avoid repeated laying of overlapping parts, and the joint spacing should be controlled at 30cm or more. After laying all the geogrids, flexible displacement sensors should be laid to monitor the changes of the geogrids in real-time. After laying all the high quality uniaxial plastic geogrid, carry out filling construction. Generally, the method of layered filling is adopted. After filling, each layer should be repeatedly compacted, and the degree of compaction should be tested to ensure that it meets the design compaction standards.
Without the geogrid, machinery and vehicles are not allowed to pass. According to the design plan and site construction inspection records, select the appropriate compaction equipment. Under normal circumstances, the test section can be selected in advance to determine the combination of compaction equipment, rolling times, and rolling speed. The rolling operation should reach the design compactness, but the uniaxial plastic geogrid for sale should not be damaged.
Before construction, use geogrid reinforcement technology to widen the roadbed. In order to achieve the best construction effect, adequate construction preparations must be made in advance. The geological conditions along the highway extension project should be investigated by professionals to master the local hydrogeological conditions and landform features as an important basis for the compilation of the construction plan.
At the same time, contact the local climate department to determine the climatic characteristics such as temperature and precipitation, avoid bad weather construction, reduce operation difficulty, and avoid quality and safety accidents. In addition to collecting information on hydrogeological and climatic conditions biaxial geogrid factory price, it is also necessary to fully understand the construction materials and vehicle loads to ensure that the materials used are tested and accepted in strict accordance with national standards, and to prevent all unqualified materials from being applied to the project. With the support of all collected materials, complete the design of the construction plan, organize all units to conduct a joint review of the plan, and adjust and modify unreasonable parts in a timely manner according to the actual situation to ensure that the requirements for roadbed widening construction are adequate Meet, and scientifically guide the implementation of each process. On-site measurement and lofting are based on the design plan.
Measure and stakeout at the construction site, measure the slope line of the subgrade structure accurately and control the width within the design standard. Under normal circumstances, the roadbed widening construction can be organized according to the 0.5m specification wholesale fiberglass geogrid, and the basic structure should be leveled and rolled, including static pressure and vibration pressure. For example, the foundation should be statically pressed twice with a 25t roller, and finally, the corners should be flattened by hand. After the static pressure is completed, the structural performance should meet the construction standards.
