Installation Instructions

 

The connection modes of HDPE double-wall bellows and b and c tubes include both mechanical connections and various thermal fusion processes. The primary methods consist of butt fusion, electrical fusion, socket fusion, flange adapter connections, and compression connections.

1. The pipeline installation should commence with an earth arc foundation. For standard soil conditions, place a 100mm thick layer of medium coarse sand on the undisturbed soil foundation or on the compacted backfill foundation beneath the pipe. If the soil quality of the foundation is subpar, use a sand-gravel base layer with a minimum thickness of 200mm, which can be structured in two layers: a lower gravel layer (particle size 5-32mm and 100-150mm thick) and an upper coarse sand layer with a thickness of at least 50mm. The base density must align with the specifications in Table 2. For soft soil foundations, if the bearing capacity is below design requirements or compromised due to construction precipitation, the foundation must first be reinforced. Once the required bearing capacity is achieved, lay the medium coarse sand foundation layer.

2. The axillary corner within the supporting angle range of the designed earth arc foundation for the pipeline must be backfilled with medium coarse sand or gravel soil. The backfilling area should extend beyond the supporting angle 2α plus 30 degrees, ensuring compactness in accordance with the technical regulations.
 

 

3. When preparing the pipeline foundation, grooves for the socket interface and sleeve connections should be excavated during the pipeline laying. The dimensions of the groove-length, width, and depth-should match the pipe joint size. Once the joint is completed, promptly backfill and compact the area with medium coarse sand.

4. For pipeline sections prone to longitudinal uneven settlement due to pipeline load or ground soil changes, reinforce the foundation prior to laying the pipeline.
For polyethylene drainage pipe foundation treatment, adopt composite methods such as sand piles or stone piles. Avoid rigid foundation treatments like driven piles, concrete pads, and concrete strip foundations.
