Most of the city's sewers are constructed using cement drainage pipes. What are the construction methods for these? Here, Hebei Lihua Cement, a manufacturer of cement pipes, guides you through the process.

Determine the Center Line of Concrete Pipes: Before construction, the starting and ending points, plane and longitudinal bend points, and straight line control points can be set using wooden stakes with center pins at the design-provided center line control points on-site. Direction control stakes should be set at appropriate locations outside the grooves at the starting, ending, and plane bend points, and stake numbers determined through measurement.

Establish Temporary Benchmarks: Concrete pipe projects often require the addition of temporary benchmarks, which should be set in stable locations that are not easily碰撞ed, with an interval of no more than 30 meters. The closure difference of the temporary benchmarks should meet the specified standards.

The trench excavation primarily uses excavators for digging and manually clearing the bottom as a supplement. The rainwater hopper connection pipes and branches are manually excavated. During the excavation process, pay attention to the changes in soil quality and use support and protection for sections showing signs of collapse.

On both sides of the groove, elevation piles are symmetrically set at 1 meter above the bottom of the groove, with equal-height elevation pins nailed to them. Before the bottom of the groove is reached and before the surface is leveled, the centerline of the channel and the elevation of the elevation piles should be remeasured.

The embankment height at the edge of the trench shall not exceed 2 meters, and the distance from the trench edge shall be no less than 1 meter. Prior to trench construction, it is essential to request pipeline information from the relevant authorities to determine the basic location of underground facilities. If necessary, a hole should be initially excavated to accurately locate the pipeline, facilitating construction and ensuring the safety of all pre-buried pipelines. During construction, support and protective measures should be implemented for exposed pipelines.
