Problems solved by technology

[0002] In the construction of municipal engineering, it is necessary to lay drainage pipes underground, but the current rows of pipes are all one-piece fixed structures, resulting in the bursting of the drainage pipes once an external construction machine cuts the drainage pipes during drainage. , leading to partial water leakage, and when the drain is fully loaded, the load pressure of the drain pipe is high, which is prone to bursting problems

Embodiment Construction

[0012] like figure 1 As shown, the municipal composite drainage pipeline includes an outer pipeline 2 with an accommodating chamber 8 in the middle of the outer pipeline 2, an inner pipeline 4 is installed in the accommodating cavity 8, and a drainage hose 7 is arranged in the middle of the inner pipeline 4. The inner pipe 4 is provided with more than one fixed part 6 around the inner pipe 4. The fixed part 6 protrudes from the inner pipe 4. There is an installation cavity in the middle of the inner pipe 4, and the drain hose 7 is arranged in the installation cavity. , the outside of the drain hose 7 is facing each fixed part with a ejector part 3, the ejector part 3 passes through the fixed part to the outer end of the fixed part and its ejector part is connected with the outer pipe 2 when draining. contact with the inner wall of the chamber.

[0013] In this embodiment, the ejector part and the drain hose are of an integrated structure, both of which are made of soft rubber...

Abstract

The invention discloses a municipal composite drainage pipe. The municipal composite drainage pipe comprises an external pipe, in which an accommodating cavity is formed; a drainage hose is arranged inside an internal pipe; more than one fixing unit is arranged outside and around the internal pipe in a protruded mode; the inside the internal pipe is provided with a mounting cavity, the drainage hose is arranged inside the mounting cavity, the outside of the drainage hose is provided with ejection units facing right towards every fixing unit, every ejection unit penetrates through the corresponding fixing unit towards the external end of the fixing unit and can be in contact with the inner wall of the accommodating cavity of the external pipe during drainage. The municipal composite drainage pipe is simple in structure and can effectively enhance the drainage capacity and avoid burst of the drainage pipe, and by means of the ejecting units, can achieve protection via the external pipe and provide pressure resistance and shear resistance through the ejecting units when under external extrusion and shear to achieve flexible support.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a municipal composite drainage pipe. Background technique [0002] In the construction of municipal engineering, it is necessary to lay drainage pipes underground, but the current rows of pipes are all one-piece fixed structures, resulting in the bursting of the drainage pipes once an external construction machine cuts the drainage pipes during drainage. , leading to partial water leakage, and when the drain is fully loaded, the load pressure of the drain pipe is large, and it is prone to bursting. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high strength, long service life, anti-extrusion and anti-shearing functions. [0004] The present invention is achieved through the following technical proposals: a municipal composite drainage pipe, comprising an outer pipe with an accommodating chamber in the middle,...
