Two conditions for directly determining the quality of cement pipes are as follows:
1. Reinforcement meshes will have tendons running and leaking in real time if there are no welding points, which will make the tube body appear non-reinforced.
2. It is difficult to center the reinforced mesh after forming. The reinforced mesh is eccentric, that is, the protective layer of the reinforced mesh is uneven; this process requires a lot of molds to ensure the output value. There is an error in the dimensions of each mold. Long-term disassembly and application will also show large deformation, which results in large errors in pipe roundness, nozzle straightness, pipe diameter scale and pipe length scale, affecting the installation quality of the project, and leakage will cause the road surface to sink. Pollution of soil and groundwater on both sides of the pipeline;
