Before burying 3PE anti-corrosion steel pipes, the surrounding environment needs to be cleaned first. The measurement and setting-out personnel need to give technical explanations to the commanders and mechanical operators participating in the cleaning work. At least one defense personnel must participate in the cleaning work of the working belt. It is also necessary to check whether the 3PE anti-corrosion steel pipe, anti-corrosion steel pipe, crossing piles, and underground structure sign piles have been moved to the spoil side and whether the above-ground and underground structures have been inventoried and the right of passage has been obtained.

Mechanical operations can be used in general areas, and bulldozers can be used to remove debris within the working zone. However, when the 3PE anti-corrosion steel pipe needs to pass through ditches, ridges, steep slopes, and other obstacles, it is necessary to find ways to meet the needs of pipe transportation 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, and vegetation around it, farmland and fruit forests should be occupied as little as possible; if pipes are buried in areas such as deserts and saline-alkali lands, surface vegetation and undisturbed soil should be damaged as little as possible to prevent and reduce water and soil erosion; when passing through irrigation canals and drainage canals, water passing facilities such as pre-buried culverts must be used so as not to hinder agricultural production.
