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 primary methods include butt fusion, electrical fusion, socket fusion, flange adapter connection, and compression connection. These techniques ensure robust and reliable connections for diverse applications.

1. The pipeline shall be laid on an earth arc foundation. For general soil quality, a 100mm-thick layer of medium coarse sand should be placed over the undisturbed soil foundation or compacted backfill. For poorer soil conditions, a base layer of at least 200mm thickness, composed of gravel with particle sizes of 5~32mm and a top layer of coarse sand, can be used. The base density must meet the specifications in Table 2. For soft soil foundations, where bearing capacity is insufficient, the foundation should be reinforced before laying the medium coarse sand layer, ensuring it meets the required strength.

2. The axillary corner within the pipeline's designed earth arc foundation must be backfilled with medium coarse sand or gravel soil. The backfilling range should extend beyond the supporting Angle 2α by at least 30 degrees. The compactness of the backfill must adhere to technical regulation standards to ensure stability.

3. Grooves for the socket interface and sleeve connection should be dug along with the pipeline laying process. The dimensions of these grooves should be determined based on the pipe joint size. Once the joint is complete, the grooves should be immediately backfilled with medium coarse sand to ensure proper density and support.

4. In areas where longitudinal uneven settlement of the pipeline may occur due to factors like pipeline load and soil changes, the foundation should be reinforced before laying the pipeline. This preemptive reinforcement helps in maintaining the pipeline's structural integrity.
For polyethylene drainage pipe foundation treatment, adopt composite methods like sand pile and stone pile. Avoid rigid treatments like driven piles, concrete pads, and concrete strip foundations to maintain flexibility and adaptability in varying soil conditions.
