Steel belt corrugated pipes have smooth inner walls and a corrugated outer wall (with shapes such as right angles, trapezoids, sine waves, etc.), formed by simultaneous extrusion of the corrugated outer wall and a smooth inner wall. **High-Density Steel Belt Polyethylene Winding Corrugated Pipe Construction Steps**: Trenching - Lowering Pipe - Connecting - Backfilling 1. **Trenching for the Pipe**: - The pipe should be laid on the original soil foundation or a compacted foundation after trenching. When the pipe is under a roadway, the soil cover over the pipe must be greater than 0.7m. The trench width should ideally be the outer diameter of the pipe plus 0.6m. - When the pipe crosses obstacles such as railways or roads, protective casings made of reinforced concrete, steel, or cast iron should be installed. 2. **Lowering the Pipe and Connection**: - For socket installation, the socket should face downstream and the spigot upstream, installed sequentially from low points to high points. - Manual installation is recommended, and lengths can be cut with a hand saw, ensuring that the cut surface is perpendicular and smooth. - During joint operations, the inner (outer) surface of the socket (spigot) should be cleaned, aligning the center of the spigot with the centerline of the socket. 3. **Connection with Inspection Wells**: - Use flexible connections; when requirements are not high, the pipe can be directly built into the well wall. 4. **Air Tightness and Water Tightness Tests**: - The seal test should be conducted after compacting the sand backfill at the pipe bottom and extrusion angles, selecting either air or water tightness testing based on site conditions. 5. **Backfilling the Pipe**: - After the pipe installation is qualified, backfilling should be done immediately. The trench should be backfilled symmetrically from both sides of the pipe line and inspection wells, taking necessary positioning measures to ensure that the structure does not shift. - From the bottom of the pipe foundation to the top of the pipe (0.7m), manual backfilling is required; for areas above 0.7m, mechanical backfilling can be done simultaneously from both sides of the pipe axis, followed by compaction and rolling. **Advantages of Steel Belt Reinforced Polyethylene Corrugated Pipe Construction**: 1. No need for a concrete pipe base during use; excavation, lowering the pipe, and backfilling can be done simultaneously, greatly shortening the construction period and reducing costs. 2. The trench width for the pipe is reduced by 20% compared to other pipe materials and does not require sloped walls, significantly reducing the amount of earthwork, saving labor, and decreasing construction difficulty and labor intensity. 3. Since the pipe is buried underground, the combined action of the pipe and soil can improve the pipe’s compressive strength; backfilling must be carried out according to requirements. **High-Density Steel Belt Polyethylene Winding Corrugated Pipe Collaboration Projects**: - Zhengzhou Airport Municipal Project Department - Tianjin Airport Logistics Center Project Department - Henan Sanmenxia Steel Plant Pipeline Project Department - Qingdao Sewage Treatment Pipeline Project Department - Qingdao Jimo Sewage Treatment Pipeline Project Department - Linyi Cangshan Sewage Treatment Pipeline Project Department - Hangzhou Municipal Sewage Pipeline Project Department - Henan Zhoukou Municipal Industrial Park Sewage Treatment Project Department **Sales Contact**: Manager Sun at 136-9888-71491.
