Installation Instructions

The connection modes of HDPE double-wall bellows and b and c tubes include mechanical connection and a series of thermal fusion procedures. The main methods employed for these connections are: butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection.

1. The pipeline installation should be based on an earth arc foundation. For general soil quality, lay a 100mm thick layer of medium coarse sand on the undisturbed soil foundation or a compacted backfill foundation below the bottom of the pipe. If the soil quality is poor, you may use a sand gravel base layer with a thickness of at least 200mm. This can be laid in two layers: the lower layer comprising gravel with a particle size of 5~32mm and a thickness of 100~150mm, and the upper layer consisting of coarse sand with a thickness of no less than 50mm. The base density should meet the requirements specified in Table 2. For soft soil foundations, if the bearing capacity is less than the design requirements or disturbed due to construction precipitation, the foundation must first be strengthened. Once the specified bearing capacity is achieved, the medium coarse sand foundation layer can be laid.

2. The axillary corner within the supporting angle range of the designed earth arc foundation of the pipeline must be backfilled with medium coarse sand or gravel soil. The backfill range should not be less than the supporting angle 2α plus 30, and the backfilling compactness must comply with the technical regulations.

3. The grooves for the socket interface and sleeve connection in the pipeline foundation should be excavated concurrently with the pipeline laying. The length, width, and depth of the groove should be determined based on the pipe joint size. After completing the joint, immediately backfill the density with medium coarse sand.

4. For sections where longitudinal uneven settlement of the pipeline may occur due to factors such as pipeline load and changes in ground soil, the foundation should be reinforced before laying the pipeline.
For the foundation treatment of polyethylene drainage pipes, adopt composite methods such as sand piles and stone piles. Avoid using rigid foundation treatments like driven piles, concrete pads, and concrete strip foundations.
