Abstract

The invention relates to a sewage pipeline blocking device and a construction method thereof. The sewage pipeline blocking device is arranged on the wall of a working well and is used for sealing a pipeline. The sewage pipeline blocking device comprises a rubber plate, a water retaining steel plate and a reserved hole pipe which are arranged in sequence, wherein the rubber plate is attached to thewell wall; first preserved holes which are corresponding in positions are respectively formed in the water retaining steel plate and the rubber plate; and the reserved hole pipe communicates with thefirst preserved holes. According to the sewage pipeline blocking device, the water retaining steel plate is used for main blocking, performs sealing water stop in combination with the rubber plate, has a relatively good blocking effect, and can ensure the construction safety in an operation area; the reserved hole pipe can realize the continuous sewage transportation, and the transportation of intake sewage of sewage treatment plants does not need to be completely stopped; the dismantling workload in later period is small; the workload of underwater frogmen is effectively reduced; and the operating risk is reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a sewage pipe blocking device and a construction method thereof. Background technique [0002] In large-scale sewage treatment projects, it is usually necessary to temporarily block the sewage pipes when the old and new structures are connected and connected, and during the cutting and chiseling construction of the connection, the sewage transportation of the sewage treatment plant cannot be stopped, that is Water cut-off construction cannot be performed. Because the old structure may have problems such as high water flow velocity, which increases the difficulty and potential safety hazards of the early diving inspection work; and during the lifting and installation of the construction supporting equipment, it may cause objects to hit, entangle, press, etc. Injuries such as falling and crushing are a very high-risk operation. [0003] The existing plugging methods in non-st...
