Large-flow suck-back siphon sewage pipe with underneath pass channel and encapsulation treatment construction method

Abstract

The invention discloses a large-flow suck-back siphon sewage pipe with an underneath pass channel. The pipe comprises an underneath pass channel, a concrete retaining wall, a steel cross beam and a sump, a sewage pipe is arranged at the bottom end of the interior of the underneath pass channel; anti-collision walls are arranged on the two sides of the underneath pass channel; a concrete retainingwall is built on the side surface of the anti-collision wall; steel pipe buttresses are fixedly mounted on the surfaces of the two concrete retaining walls; a steel cross beam is fixedly installed atthe top ends of the steel pipe buttresses, a first steel pipe and a second steel pipe are arranged on the surface of the steel cross beam and fixedly installed on the surface of the steel cross beam through a steel tie, one end of the first steel pipe is inserted into a first sewage well, and the first sewage well is arranged on one side of the concrete retaining wall. Compared with a traditionalsewage pipe replacement seepage preventing and blocking technology, sewage pipes can be replaced under the condition that smooth drainage of large-flow sewage of the suck-back siphon is guaranteed, normal municipal sewage drainage is not affected, and unnecessary communication contradiction between resident life and municipal construction is avoided.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a large-flow backsiphon sewage pipe that passes through an underpass. Background technique [0002] The existing technology is to use earth filling to form a cofferdam, and lead the sewage from the culvert pipe interface to a suitable discharge location. If the water flow of the sewage pipe is large, multiple pumps are used to pump water to avoid large-scale water accumulation and affect on-site construction. [0003] The shortcomings of this technology: For the treatment of a large number of sewage pipes bursting with back siphons, due to the effect of back siphons, the water flow is huge, and the method of cofferdam drainage cannot completely guide the water into the designated position, even if the water pump is used. If it can be completely treated, the accumulation of water will definitely affect the site construction and cause damage to construction machinery and equipment. ...

Problems solved by technology

[0003] The shortcomings of this technology: For the treatment of a large number of sewage pipes bursting with back siphons, due to the effect of back siphons, the water flow is huge, and the method of cofferdam drainage cannot completely guide the water into the designated position, even if the water pump is used. It can be completely treated, and the accumulation of water will definitely affect the on-site construction and cause damage to construction machinery and equipment.

Using traditional cofferdams or drainage methods cannot guarantee smooth drainage without affecting the on-site work site

And when the old culvert pipes are replaced, it will definitely affect the lives of the surrounding residents, causing unnecessary conflicts between the construction of municipal buildings and the surrounding residents
