Installation Instructions

Discover the seamless adaptability of our HDPE double-wall bellows, offering versatile connectivity with b and c tubes through both mechanical connections and an array of sophisticated thermal fusion processes. Key methods include precision butt fusion, efficient electrical fusion, snug socket fusion, robust flange adapter connection, and secure compression connection.

1. The pipeline should be securely based on an earth arc foundation. For typical soil conditions, a stable layer of medium coarse sand, measuring 100mm thick, should be placed on undisturbed soil or on a properly compacted backfilled foundation beneath the pipe's base. In situations where the foundation soil is suboptimal, employ a sand-gravel base no less than 200mm thick. This can be done in two layers: the lower layer should consist of gravel (5~32mm particle size) with a thickness of 100~150mm, while the upper layer should be coarse sand no less than 50mm thick. Ensure the base density adheres to the standards in Table 2. In the case of soft soil foundations, if the bearing capacity is inadequate or compromised by surface disturbances due to factors like construction-induced precipitation, first reinforce the foundation. Once it achieves the designated bearing capacity, proceed to lay the medium coarse sand foundation layer.

2. To ensure stability, backfill the axillary corner within the designed supporting Angle range of the earth arc foundation using medium coarse sand or gravel soil. This backfilling must extend beyond the supporting Angle 2α by an additional 30 degrees, adhering strictly to the compactness requirements outlined in technical standards.

3. In the pipeline foundation, grooves for socket interfaces and sleeve connections must be excavated concurrently with the pipeline installation. Dimensions of length, width, and depth should match the pipe joint specifications. After joint completion, backfill promptly with medium coarse sand to maintain density.

4. In areas prone to longitudinal uneven settlement due to pipeline load or soil changes, reinforce the foundation prior to laying the pipeline to ensure structural integrity.
For polyethylene drainage pipe foundation treatment, employ sophisticated composite methods like sand piles or stone piles. Avoid rigid solutions such as driven piles, concrete pads, and concrete strip foundations, which may not offer the adaptability required for our advanced drainage systems.
