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 3PE anti-corrosion steel pipes, crossing piles, and underground structure sign piles have been moved to the side of the spoil, 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 pipes need to pass through ditches, ridges, steep slopes and other obstacles, you need to find ways to meet the needs of pipe transportation and construction equipment. access requirements.
The construction work area should be cleaned and leveled as much as possible, and if there are farmland, fruit trees, and vegetation around it, it should occupy as little farmland and fruit forest as possible; if it is a desert or saline-alkali land where pipes are to be buried, 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.
