1. Prevent pipe inversion

The support body of the soft permeable pipe is a high-strength steel wire ring, which has high strength and can withstand a certain amount of soil covering pressure. But it is best to fix both ends first, and then fill with soil to avoid the soft permeable pipe from collapsing due to uneven horizontal thrust.

2. Preparation for laying

Firstly, the lower layer should be leveled and rolled, with a flatness of no more than 15mm and a compaction degree that meets the design requirements. Hard protrusions such as crushed stones and block stones are strictly prohibited on the surface.

3. Pipe connection

Direct connection: Remove the supporting steel wire ring from one end of the pipe, cut the outer covering material, insert it into another section of the pipe, and tie it tightly with a wire rope.

T-pipe connection: Remove the supporting steel wire ring from the end of the branch pipe, cut off the outer covering material, and then bundle it.

End treatment: Remove a section of the supporting steel wire ring from the end and tie it with nylon rope.

When paving, it should be straightened, smooth, and tightly attached to the lower bearing layer, without distortion, wrinkles, or overlap. The overlap should be fixed with U-shaped nails or connectors
