Temporary plugging device for side wall embedded pipe

Abstract

The invention relates to the field of buildings, and discloses a temporary plugging device for a side wall embedded pipe. The device comprises a plugging plate, a circle of water swelling water stop strip is arranged on the inner side of the plugging plate, the outer wall of the water-swelling water stop strip is attached to the inner wall of the embedded pipe, multiple steel bars are arranged onthe inner side of the plugging plate, the steel bars comprise linear parts and bent parts, the linear parts of the steel bars are connected with the inner side of the plugging plate, one ends of the bent parts are connected with the linear parts, and the other ends of the bent parts abut against the inner wall of the embedded pipe. According to the device, when the embedded pipe needs to be temporarily plugged, the multiple steel bars extend into the embedded pipe, the bent parts of the steel bars abut against the inner wall of the embedded pipe, and the plugging plate can be fixed to a side wall; when water exists in the embedded pipe, the water swelling water stop strip expands and can fill a gap between the plugging plate and the side wall so that the embedded pipe can be tightly plugged, and the leakage is prevented; and when the embedded pipe does not need to be plugged, only the plugging plate needs to be pulled out, the operation is rapid and convenient, and the structure of theside wall cannot be damaged.

Description

technical field [0001] The invention relates to the construction field, in particular to a temporary sealing device for a side wall pre-buried pipe. Background technique [0002] Embedded pipes are pipes that are pre-filled in construction projects to facilitate subsequent construction, so as to facilitate the installation of ventilation pipes, air-conditioning pipes, and drainage of water and sewage in underground building structures. When constructing an underground building structure, it is necessary to set a reserved hole on the side wall to facilitate the filling of the embedded pipe, and the embedded pipe is often not used in a short period of time, so it is necessary to temporarily block the embedded pipe. In the prior art, when the pre-buried pipe is temporarily blocked, the plugging is not tight, which often causes leakage of the underground building structure, and in severe cases, it will affect the normal use of the underground building structure. , will increase...

Problems solved by technology

In the prior art, when the pre-buried pipe is temporarily blocked, the plugging is not tight, which often causes leakage of the underground building structure, and in severe cases, it will affect the normal use of the underground building structure. If concrete and other solid materials are used to block the pre-buried pipe , it will increase the difficulty of re-opening the hole later, and it will damage the structure of the side wall
