5. On both sides of the trench and 1m above the bottom of the trench, elevation piles shall be set symmetrically, and elevation nails of equal height shall be nailed on them. The center line of the pipe channel and the elevation of the elevation pile shall be re measured before the bottom of the trench is reached and the pouring is leveled. 6. The height of soil piling on one side of the trench shall not be more than 2 meters, and the distance from the trench edge shall not be less than 1 meter. The protection of underground pipelines for trench construction shall be disclosed to the relevant departments first to clarify the basic location of underground facilities. If necessary, sample holes shall be excavated first to find out the exact location, facilitate construction, and ensure the safety of various embedded pipelines, Support protection measures shall be taken for exposed pipelines.

The general defect is corrosion, which mainly includes pitting and erosion. These two corrosion modes are chronic and not easy to be found by testers. The other is stress corrosion cracking, which is caused by corrosion, tension and stress at the same time. Mechanical damage is also a defect of cement pipes, mainly including gouges and dents with gouges, which are usually caused by mechanical loss. External crack defects are plane defects of cement pipes, which are easy to be found. Peeling is a serious wear condition, and perforation will cause fracture or leakage. Therefore, cement pipes should be tested in time. Once defects are found, corresponding repair measures should be taken immediately to eliminate potential safety hazards and ensure safety.

The bending resistance of thin-walled pipe piles is poor, especially the poor shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building. Therefore, some national prestressed concrete pipe pile research meetings have clearly sent out information that the shear resistance and tensile resistance of pipe piles should be specified, and pipe piles should be carefully used in key projects, At the meeting, various experts demonstrated and looked forward to the pile type with square or polygonal external surface, hoping that China could move closer to the western developed countries and develop the foundation pile material with polygonal or variable diameter external surface. The prestressed concrete hollow square pile was developed for this purpose.

Properly control the water cement and cement consumption. The water cement ratio is the main factor determining the compactness of concrete, which not only affects the strength of concrete, but also seriously affects its durability. Therefore, strictly control the water cement ratio. Ensuring sufficient cement consumption can also improve the compactness and durability of concrete. The quality of cement pipe depends on these factors, and its quality is very important. The cement pipe with poor quality will expose defects in the process of use, which will affect the normal work.
