Are buried plastic pipes covered with sand?

Answer:

Soft soil foundation treatment according to the design requirements. It should be a homogeneous bedding cushion. The drain pipe seems to be more strict, made 400 double bellows, is the following 100 beans stone coarse sand cushion, pipe top 500 fill sand. This procedure requires that 150 thick sand cushions be made when the channel is in debris and the rock is at the base.
There is no specific description of the standard, general stone ground laying plastic pipe, pipe laying requirements with fine soil or sand bed.I don't know what you're talking about
In general areas, the laying of plastic pipes, plastic pipes can be directly placed at the bottom of the ditch, there is no need to do another special pipe foundation, the soil is loose parts of the region, the ditch should be artificially rammed.
Only when the plastic pipes are laid at the bottom of the stone trench, will the 100mm soil or sand be placed on the top and bottom of the plastic pipes.
