Since the laying of cement pipes is mostly underground, the management of underground projects must be carried out in accordance with strict construction routes to ensure the smooth progress of the project. Let's take the laying of underground pipelines in strict accordance with a certain process. The laying of cement pipelines is carried out through measuring and laying lines-trench digging-pipeline foundation construction-laying of pipelines and pipe cleaning-concrete pouring inspection wells-township pouring -Trench backfilling. There are several processes. In the meantime, the primary foundation process is the measuring and putting out line. The measuring and putting out line is performed by a full-time measuring operator, which requires strict setting records and instruments that pass the school inspection. The detection and measurement requirements here are very high standards and require precision. According to the design drawings and cross column records, check the level point, establish a temporary level point, do a good job of protection, and conduct closed retesting and control the elevation.
In addition, after the trench is dug, the elevation of the elevation should be compounded in time to control the elevation of the excavated soil, the cushion and the root surface; and then compacted with a strip of stone to compact the soil. The order of piping shall be in the direction from low to high. Attention must be paid to necessary problems in construction
