As one of the indispensable equipment in urban construction, the construction of cement pipelines is also a relatively important operation. Wanxin cement pipeline manufacturers provide us with the latest and most useful cement pipeline installation methods.
First, the crane is used for unloading, and artificial assistance is put in place. Generally, rigid joints are used for pipe joints, and a deformation joint is provided every 10m.
Construction sequence of pipe network: measuring and laying line → trench excavation → pipeline foundation construction → laying of pipeline pipe for cleaning up → concrete pouring inspection well → town filling → trench filling
Detailed construction steps:
1. The full-time surveyor is responsible for the measurement and line-up operations. Strict measurement records and guidelines for file verification are selected. Instruments that have been calibrated are selected. According to the plan drawings and pile crossing records, check the level point, establish a temporary level point, do a good job of protection, and conduct closed retesting to control the elevation.
2. After the trench excavation is completed, review the elevation elevation in time to control the elevation of the excavated soil, cushion and root surface. Then the stone is squeezed and compacted, soil is removed, steel bars are laid, wooden boards are erected, and then the ground is poured.
3. Before the pipe is lowered, select the level to control the elevation of the pipe top. The order of the pipe is arranged from low to high. The pipe is in place and then manually adjusted with an excavator. The socket should face the upstream direction, and the inner wall of the socket should be scrubbed with water, so that the rubber ring can slide in smoothly during intubation, which is convenient for the device. .
4. Pipeline equipment should be backfilled immediately after acceptance. At least the pipe diameter should be backfilled to the top of the pipe. During backfilling, there must be no stagnant water in the base trench. Except for the coarse sand in the backfill of the required part, the excavated sandy soil is used for the backfilling information of the pipe trench. Stone soil shall not be used for backfilling.
The above method is currently the most widely used cement pipeline installation plan. Wanxin cement pipeline manufacturers not only provide high-quality and low-cost cement pipelines, but also provide technical support to users with any technical problems.
