What needs to be done before burying 3PE anti-corrosion steel pipes

Before burying 3PE anti-corrosion steel pipes, the surrounding environment needs to be cleaned up first. The surveying and laying-out personnel need to give technical instructions to the commanders and machine operators who participate in the cleaning work. At least one line of defense personnel must participate in the cleaning of the operation zone. It is also necessary to check whether the 3PE anti-corrosion steel pipes, crossing piles, and underground structure marker piles have been moved to the abandoned soil side, whether the above-ground and underground structures have been counted, and whether the right of passage have been obtained.

Mechanical operations can be used in general areas, and bulldozers can be used to clear the debris in the operation zone. However, when spitting 3PE anti-corrosion steel pipes through obstacles such as ditches, ridges, and steep slopes, it is necessary to find a way to meet the traffic requirements of transportation management and construction equipment.

The construction work area should be as clean and flat as possible, and if there are farmlands, fruit trees, and vegetation around them, the occupation of farmlands and fruit trees should be minimized; if there are deserts or saline-alkali lands, the surface vegetation and original soil should be damaged as little as possible to prevent and reduce soil erosion; when passing through irrigation channels and drainage channels, pre-buried culverts and other water-passing facilities should be used, and agricultural production should not be hindered.
