Since most of the laying of cement pipes is underground, the handling of underground projects must follow the strict construction route 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 measured by laying lines-trench excavation-construction of pipeline roots-laying of pipelines, cleaning of pipes-concrete pouring inspection wells-township pouring -Trench backfilling: There are several processes. In the meantime, the most important foundation process is the measurement and pay-off. The measurement and pay-off is performed by a full-time survey operator, which requires strict measurement records and equipment that passed the check. Testing and measurement here require high standards and require precision. According to the plan drawing and the 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, it is necessary to compound the elevation elevation 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, lay the steel bars, erect the formwork, and then pour the ground. . The order of piping should be arranged from low to high. Attention must be paid to the necessary problems in construction. Guangzhou Wanxin Cement Products Co., Ltd., welcome friends to buy!
