Deep Well Point Connection Structure and Construction Method of Old and New Sewage Pipelines

Abstract

The invention relates to a new and old sewage pipeline deep well point connection structure which comprises a foundation pit supporting structure, a new and old sewage pipeline inspection well structure and a sewage pipeline suspension device. The foundation pit supporting structure comprises steel sheet piles, drainage ditches, bracing plates, supporting plates, transverse rods, inclined struts and grooves. The new and old sewage pipeline inspection well structure comprises a blocking pipe, a solid base, a fixed base, a split bolt hole, a solid block, an old pipe communicating pipe, a new pipe communicating pipe, a splicing circular ring, a splicing circular groove and a well chamber. The sewage pipeline suspension device comprises a sliding rail, a sliding collecting machine, a top connecting transverse rod, a lifting rope, a sliding wheel, a supporting column, a lifting ring, an outwards-extending rail and a lifting hook. The invention has the beneficial effects that the three communicating pipes arranged on the inspection well are matched with the blocking pipe, so that continuous flow construction of new and old sewage pipes can be realized. The inspection well is constructedin an assembling mode, and the construction time is greatly shortened.

Description

technical field [0001] The invention relates to the field of sewage pipes, in particular to a deep well point connection structure and construction method of old and new sewage pipes. Background technique [0002] Underground sewage pipes are pipes buried underground for transporting sewage discharged from the upper part, and are used in cities, roads, sewage plants, underground projects, etc. During the use of sewage pipes, it needs to be repaired, and some severely damaged pipelines need to be replaced. What's more, the original pipelines need to be discarded and new sewage pipes should be used to replace the old sewage pipes. During the construction of traditional new and old sewage pipes, the sewage discharge function of the old sewage pipe is permanently closed, and then the construction of the new sewage pipe is carried out, and finally the two pipes are connected together at the intersection of the old and new sewage pipes. Due to the long construction period of the ...

AI Technical Summary

Problems solved by technology

Due to the long construction period of the new and old sewage pipes, there is nowhere to discharge the cut-off sewage, which will have an adverse impact on the original environment. If it is serious, it will cause too much water accumulation on the road and make it impossible for vehicles to drive.
