Drainage pipeline pocket-shaped water plugging device and construction installation structure and water plugging and unplugging method

Abstract

The invention discloses a drainage pipeline pocket-shaped water plugging device. The drainage pipeline pocket-shaped water plugging device comprises a pocket with an upper opening. According to a construction installation structure of the water plugging device, a plurality of vertical shafts communicated with each other are arranged above a drainage pipeline which is transversely arranged, the pocket is arranged in the vertical shafts, and a steel wire rope penetrates through rope holes in the opening to be fixed at the shaft openings of the vertical shafts, filling materials fill the pocket from the opening, and the vertical shafts and the drainage pipeline at the bottoms of the vertical shafts are sealed and blocked until the bottom of the pocket filled with the filling materials expandsoutwards. A water plugging and unplugging method of the water plugging device comprises the following steps that 1) the pocket is put, wherein the pocket is put from the vertical shafts, and the bottom of the pocket makes full contact with the drainage pipeline which is transversely arranged; 2) the opening of the pocket is fixed at the shaft openings; 3) the materials are poured, the filling materials are poured into the pocket from the opening of the pocket, so that the bottom of the pocket is expanded to the periphery and is diffused until the drainage pipeline is completely closed; and 4)operation and unplugging are carried out, wherein the filling materials are taken out after the operation is completed, and then the pocket is taken out. According to the drainage pipeline pocket-shaped water plugging device, the technical problems that an existing air bag water plugging device is prone to being cracked, water leakage easily occurs in the case of plugging through a steel plate, and dismounting of the steel plate is difficult can be solved.

Description

technical field [0001] The invention relates to the field of plugging devices for water supply and drainage pipes, in particular to a pocket-shaped water blocking device for drainage pipes, a construction and installation structure, and a water blocking and removing method. Background technique [0002] At present, there are generally two methods for water blocking of drainage pipes, one is to block with air bags, and the air is released during removal. Its disadvantages are as follows: 1) the safety is not high, due to reasons such as rubber fatigue, excessive air pressure and sharp objects, the airbag will easily explode and hurt people; 2) the installation is inconvenient. It requires multiple people to coordinate and carry it together, or a crane is needed to put the air bag into the underground pipeline; 3) The use is limited. When there is silt or solid waste in the pipeline, the airbag cannot be installed, and the cross section of the pipeline is square or other non-c...
