What needs to be done before 3PE anti-corrosion steel pipe is buried

Before the 3PE anti-corrosion steel pipe is buried, it is necessary to clean up the surrounding environment. The measurement and release personnel need to make technical disclosures to the commanders and mechanical operators who participate in the cleaning work, and at least one line of defense personnel should be involved in the cleaning work of the operation belt. It is also necessary to check whether the 3PE anti-corrosion steel pipe, the crossing pile, and the underground structure marker pile are translated to the spoiled side, whether the above-ground and underground structures have been counted, and whether the right to pass has been obtained.

In general areas, mechanical operations can be used, and bulldozers can be used to remove the sundries in the operation belt. However, when the 3PE anti-corrosion steel pipe needs to pass through obstacles such as ditches, ridges, and steep slopes, it is necessary to find a way to meet the requirements of transportation pipes and construction equipment. access requirements.

The construction work zone should be cleaned and leveled as much as possible, and if there are farmland, fruit trees, vegetation, and other fields around, the farmland and fruit forest should be occupied as little as possible; if it is desert, saline-alkali land, where pipes are buried, the surface vegetation and undisturbed soil should be damaged as little as possible to prevent and reduce soil erosion; when passing through irrigation canals and drainage canals, the method of pre-buried culvert pipes and other water-passing facilities should be used so as not to hinder agricultural production.
