Alternation construction connection structure of new and old sewage connecting pipes

Abstract

The invention discloses an alternation construction connection structure of new and old sewage connecting pipes, which comprises several PCCP pipes, an original sewage connecting pipe, a square channel three-dirt connecting pipe; the adjacent PCCP pipes are connected, the PCCP pipes are connected with the square channel three-dirt connecting pipe, and inserted to the square channel three-dirt connecting pipe from the side face; manholes are arranged at the joint of the PCCP pipes and the joint of the PCCP pipes and the square channel three-dirt connecting pipe from the side face. Through applying a transition connecting pipe to connect the PCCP pipes and the square channel three-dirt connecting pipe, the side face opening of the original sewage connecting pipe is connected with the PCCP pipe, and further provided with a coating square well; for the structure is a low-pressure pipe, manholes are required to arrange; adjacent PCCP pipes arranged with the manholes are connected by three sections of steel pipes and reinforced by the steel sleeve ring while further sealed and reinforced by the coating square well. The alternation construction connection structure is simple in structure,stable in connection, good in sealing property, and safe in use; the service life of the sewage pipe is greatly improved, thus the pipe can adapt to different using environments.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an alternate construction connection structure of new and old sewage connecting pipes with simple structure, convenient construction and good safety performance. Background technique [0002] For fully enclosed underground construction sections, it is sometimes necessary to relocate the three-sewage connecting pipe, and the local new three-sewage connecting pipe needs to be connected with the old three-sewage connecting pipe. The shapes of the pipes are different, and the pipes are covered with deep soil, and the sewage is continuously discharged, which brings major problems to the construction progress and greatly affects the construction progress and quality. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the object of the present invention is to provide a new and old sewage connecting pipe alternate cons...
