Construction scope determined Liantang wireless charging bracket : Arrange the combination of technical leader and technical personnel with reliable measurement technology According to the construction drawings, the construction scope and the middle line of the road are specifically measured to the site Liantang wireless charging bracket , and specified with white and gray lines. 4. The "layered filling method" is used to fill the filling section of the construction site by layers. The use of three-wheel roller, combined with the grader, in the degree of compaction to meet the requirements Liantang wireless charging bracket case the roadbed is formed once.
In the backfill compaction operation, it should be symmetrical backfill compaction, keep the structure intact, and the thickness of each layer of loose paving is not more than 15cm. (2) Subgrade construction technology Soil cutting excavation first remove the riverbed topsoil and weeds within the excavation scope of Xiangjiang River, and then start from the place with rich gravel, dig layer by layer from top to bottom. Transverse excavation method is used. The gravel position of Xiangqing should be investigated first, the proposed construction should be carried out now, and the construction should be carried out after the approval of the supervision engineer of Zaobao.
Subgrade applicationConstruction scheme: The construction is carried out by using dump truck with excavator, bulldozer coarse and flat grader, and vibration roller rolling method. The filling is carried out in layers and sections, and the rolling is slightly higher than the optimal water content. The filling material shall be spread in parallel layers, and the thickness of each layer shall be determined by test.
When the pipeline is located within the subgrade, the backfill compaction degree of the trench should meet the current national standard, and the road roller should not be compacted within 50cm above the top of the pipe. When the thickness of soil cover from the top surface of the pipeline structure to the road bed is not more than 50cm, the pipeline structure should be reinforced. when
