Technical Field

[0001] The utility model belongs to the technical field of municipal drainage pipes, in particular to a municipal sewer drainage pipe. Background Art

[0002] At present, in the municipal drainage system of urban streets, drainage pipes are an indispensable and important part, which are the basic components and connection hubs in the drainage network system. Most of the existing drainage pipes are buried deep underground. When in use, the water flow in the pipes will squeeze the inner wall of the pipes, which will cause compression damage to the inner wall, which can easily cause the drainage pipes to burst. Since most of the drainage pipes are buried deep underground, it is very inconvenient to repair them; therefore, it is necessary to improve them.

[0003] In the prior art, a Chinese patent with publication number CN205421494U discloses a municipal drainage pipe. The buffer layer and the buffer cavity inside it, in cooperation with the armor layer one and the armor layer two, can make the drainage pipe have better pressure resistance and extend its service life; the anti-corrosion layer on the outer protective pipe and the inner protective pipe can make the outer protective pipe and the inner protective pipe have better corrosion resistance and effectively improve their durability.

[0004] However, the above-mentioned prior art cannot take into account both the rigidity and flexibility of the ring at the same time, is inconvenient to perform bending construction at the position where bending is required, and cannot accelerate drainage and reduce noise, and cannot meet the use requirements. Utility Model Content

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a municipal sewer drainage pipe, which effectively solves the problems that the municipal sewer pipes in the prior art cannot take into account both ring rigidity and ring flexibility at the same time, it is inconvenient to carry out bending construction at the position where bending is required, and it cannot accelerate drainage and reduce noise. It is a new type of municipal sewer drainage pipe.

[0006] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a municipal sewer drainage pipe, including a sewer pipe body, the sewer pipe body is composed of a double-layer structure, the outer layer is an outer corrugated pipe, and the inner layer is an inner base pipe.

[0007] In order to enhance the ring rigidity and ring flexibility and facilitate construction, the outer layer corrugated pipe includes low corrugations and high corrugations, the low corrugations and high corrugations are arranged alternately, and the diameter of the low corrugations is smaller than the diameter of the high corrugations.

[0008] In order to reduce noise and accelerate water flow, the inner base pipe includes a base pipe, a reinforcing beam and a water flow guiding protrusion. The base pipe is arranged on the inner side of the outer corrugated pipe, four groups of reinforcing beams are arranged on the base pipe, and a water flow guiding protrusion is arranged on the inner wall of the base pipe.

[0009] Furthermore, the water flow guiding protrusion is arranged in a spiral shape.

[0010] Furthermore, the length of the sewer pipe body is 13000 mm.

[0011] Furthermore, the low corrugation and the high corrugation are made of PE material, and steel belts are arranged inside the low corrugation and the high corrugation.

[0012] Furthermore, the outer diameter of the base pipe is 10150 mm.

[0013] The beneficial effects achieved by the utility model using the above structure are as follows: this solution increases the annular rigidity and compression resistance of the pipe by arranging an outer corrugated pipe, and the annular flexibility facilitates construction, and reduces noise and accelerates the water flow rate by arranging an inner base pipe. It effectively solves the problem that the municipal drainage pipe in the prior art cannot take into account both annular rigidity and annular flexibility at the same time, it is inconvenient to perform bending construction at the position where bending is required, and it cannot accelerate drainage and reduce noise. This is a new type of municipal sewer drainage pipe. BRIEF DESCRIPTION OF THE DRAWINGS
