Cement pipe is a large pipe made of cement and steel bars. In addition to being used as a city sewage pipe, it is also used in some special factories and mines.
Determining the centerline of the pipeline: The construction pro can draw a given centerline control point according to the original, and measure the starting point, end, plane, and break point at the scene, set it to a point with a stake mark in the middle, and set the point just after the measurement A directional control pile is set on it, and the pile number is determined by measuring on. Establish a temporary level: Pipeline projects often need to increase the temporary level, which is about Anjing and it is not easy to be set out. The approximate moment is preferably not less than 30 meters. For the time being, the key closed length should meet the required specifications.
The pipe body of the cement pipe has very good heat resistance, fire resistance and excellent flame retardant effect; its non-metallic pipe body information letter will not have magnetism, single-core cable in the pipe, transmission will not worry about eddy current and so on. Cement pipes are mainly used in underground cable protection pipes, underground optical cable protection pipes, chimneys, irrigation pipes, and can also be used for groundwater and gas discharge.
General cement pipes are of large caliber. With the same caliber, the wall thickness of steel pipes can hardly guarantee a certain economy. However, most of the cement pipes are buried underground, and the corrosion protection of the cement pipes will be relatively stable. There will be some messy drainage conditions in urban drainage, and cement pipes can corrode most materials.
