Winding structure wall carat pipe, urban pipe network reconstruction pipe

In the urban pipe network renovation project, the selection of pipes is directly related to the long-term operation of the drainage system. Winding structural wall carat pipe has gradually become one of the key pipes to be considered when upgrading sewage and drainage pipe networks due to its unique molding process and structural design. This kind of pipe is formed by hot winding, and the pipe wall is composed of a flat inner wall and external special-shaped reinforcing ribs. It realizes high ring stiffness while saving raw materials, and can withstand deep soil and dynamic traffic loads to meet the needs of buried use under urban main roads.

Pipe network transformation often faces complex conditions such as dense underground pipelines and limited construction space. Winding structural wall carat pipe interfaces are usually connected by socket-type fused connection or rubber ring sealing socket connection, which does not require large lifting equipment during installation and is relatively simple to operate. The tightness of the interface has been tested by water tightness and air tightness, which can effectively resist groundwater infiltration and sewage exfiltration, and helps to maintain the stability of the surrounding soil. In the trenchless repair process, the lighter pipe weight also reduces the construction difficulty and can adapt to old pipe interspersing or short section replacement and other operation methods.

In terms of durability, the inner wall of the pipe is smooth, the water transmission resistance is small, and it is not easy to scale in long-term operation. Polyethylene material has good chemical corrosion resistance, and has stable tolerance to common acid and alkali components in domestic sewage, rainwater and some industrial wastewater. Under the premise of correct design and standardized construction, the overall service life of the pipe network system can be reliably guaranteed. For different geological conditions, the rib structure and wall thickness can also be adjusted to form a product sequence with rich ring stiffness grades, providing flexible choices for transformation programs.

In the scenes of rain and sewage diversion reconstruction in old urban areas, closure of confluence pipe network, and water outlet pressure section of pumping station, the winding structure wall carat tube is playing an increasingly important role. When selecting the type, it is necessary to comprehensively calculate the parameters such as the soil cover depth of the pipe top, the groundwater level and the traffic load to ensure that the ring stiffness and deformation rate of the pipe meet the design requirements. Only by scientifically selecting materials and standardizing construction can the urban underground vein run more safely and smoothly.
