[0002] Regardless of the collection model used in existing rural domestic sewage treatment, pipe network construction is required, and the efficiency and quality of pipe network construction can impact the overall project image. HDPE double-wall corrugated pipe is primarily used for diversion pipes in rural domestic sewage treatment. Hot-melt connection is generally preferred for double-wall corrugated pipes, which offers better connection quality and greater leak-proof interface. However, construction efficiency is low, and the complex electrical environment on-site in agricultural sewage projects poses safety risks. Therefore, socket-and-spigot connections are generally used in agricultural sewage projects for their speed and convenience. Existing bellows tensioners only have a half-circle clamp, which easily falls off during tensioning, while full-circle clamps are inconvenient to remove. Utility Model Content
