Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a PP double-wall corrugated pipe used for municipal sewage discharge. Background Art

[0002] PP double-wall corrugated pipe is a pipe material specially used for municipal sewage drainage. Its main function is to transport sewage safely and efficiently to achieve the smooth operation of the urban sewage system. PP double-wall corrugated pipe can be adjusted and optimized according to different municipal engineering needs and geological conditions. It has a double-layer structure design with a smooth inner wall to reduce fluid resistance and a corrugated outer wall to enhance the overall strength of the pipe. This structure can ensure the smooth flow of sewage while providing sufficient mechanical strength to resist external pressure and impact. In addition, PP double-wall corrugated pipe should also have the characteristics of corrosion resistance and aging resistance, and be able to adapt to various environmental conditions to meet long-term municipal sewage needs.

[0003] After searching, the patent number "CN220302726U" mentioned in the text that "the utility model discloses a PP hexagonal reinforced double-walled corrugated pipe, which relates to the technical field of corrugated pipes. In order to solve the problem that when the existing corrugated pipes are stacked up and down, the upper corrugated pipe will cause surface extrusion to the lower corrugated pipe, and the large number of corrugated pipes will easily cause the surface of the corrugated pipe to be dented and damaged, and when in use, the outer wall is also easily damaged by pressure, resulting in low strength. A first connector is provided at one end of the corrugated pipe, and a second connector is provided at the other end of the corrugated pipe, and the first connector and the second connector are both integral structures with the corrugated pipe, and a corrugated pipe cavity is provided inside the corrugated pipe, and the corrugated pipe cavity passes through the corrugated pipe, the first connector and the second connector. The second connector also includes: a reinforcing rod, which is arranged inside the cavity of the bellows, and a plurality of the reinforcing rods are arranged; a first connecting column, which is arranged on the inner wall of the upper end of the cavity of the bellows, and a second connecting column is arranged on the inner wall of the lower end of the cavity of the bellows. When in use, the hexagonal design improves the stability of the placement of the bellows, and it is not easy to deviate and shake. The force-bearing area is increased when stacked, and the overall strength is further improved. By arranging the reinforcing rod inside the cavity of the bellows, it is not easy to be dented and damaged when squeezed. However, when the utility model is in use, the design of the internal support will cause dirt to accumulate, and congestion will occur after long-term use, and the hexagonal design will reduce the pressure resistance of the joint.
