Embodiment

[0015] Such as figure 1 and figure 2 As shown, a sewage pipe for installation by pipe jacking method includes a pipe jacking body 1 . The outer diameter of one end of the pipe jacking body 1 is provided with a steel sleeve 2, and the outer diameter of the other end of the pipe jacking body 1 is provided with an annular groove 1-1.

[0016] There are two annular grooves 1-1.

[0017] The wall thickness of the pipe jacking body 1 is equal to 10% of the inner diameter 1-2 of the pipe jacking body. In the figure: T represents the wall thickness, φD represents the inner diameter of the pipe jacking body 1-2. For example, the inner diameter φD is 1200mm, and the wall thickness T is 120mm.

[0018] The cross section of the pipe jacking body 1 is circular. That is, the pipe jacking body 1 is a round pipe.

[0019] The invention is a concrete cement pipe. The wall thickness of the pipe jacking body 1 of the present invention is the best when equal to 10% of the inner diameter 1...

Abstract

The invention relates to a discharge pipe, in particular to a discharge pipe for pushing method installation. The bucket lifting machine comprises a pushing pipe body (1), wherein the outer diameter of one end of the pushing pipe body (1) is provided with a steel sleeve (2), and the outer diameter of the other end of the pushing pipe body (1) is provided with an annular groove (1-1). After the technical scheme is adopted, the discharge pipe has the advantages that the outer diameter of one end of the pushing pipe body (1) is provided with the steel sleeve, rigidity of the end is enough during pushing pipe body installation, and therefore the discharge pipe is high in strength, strong in soundness, good in reliability, long in service life and simple in structure; and the outer diameter of the other end of the pushing pipe body (1) is provided with an annular groove, a seal part can be filled in the annular groove during using, and therefore the discharge pipe is good in seal performance, prevents the leakage phenomenon, and is reliable to seal, low in seal cost and high in cost performance.

Description

technical field [0001] The invention relates to a sewage discharge pipe, in particular to a sewage discharge pipe for installation by pipe jacking method. The invention is suitable for use in underground sewage discharge. The invention belongs to the technical field of water supply and drainage device manufacturing and processing. Background technique [0002] In the underground water supply and drainage such as sewage treatment in many fields of water conservancy, industry and urban construction, the sewage pipe is an indispensable and important part, and is the basic component unit and important connection hub in the water supply and drainage pipe network system. Existing sewage pipes are varied. [0003] Among them, there are also many types of sewage pipes for pipe jacking installation, which are generally concrete cement pipes, and their structure includes the pipe jacking body. Although the sewage pipes used for pipe jacking installation are widely used at present,...
