Description

Anti-seepage device for water supply and drainage pipe plate of building engineering

Technical Field

The utility model relates to the technical field of seepage prevention of drainage pipe plates, in particular to a seepage prevention device for a water supply and drainage pipe plate in building engineering.

Background

The design and installation of water supply and drainage pipes are essential for modern buildings, especially high-rise buildings. During construction, the wall is first built or the plates between layers are poured. And holes for installing pipelines are reserved at the positions where the water supply and drainage pipes pass through so as to be convenient for installing the water supply and drainage pipes at the later stage of building construction engineering. And cement mortar is poured between contact holes between the pipeline and the wall body or the floor slab in the installation process so as to prevent leakage and seepage. However, due to the technical difficulty of secondary grouting for hole plugging, the difficulty in controlling the water cement ratio, the large workload and the high operation requirement, in actual construction, after the hole plugging treatment is performed for the first time in one house, the seepage-proofing qualification rate only reaches about 70%, the qualification rate can be met after repeated treatment, and the existing drainage pipe can leak after a long time.

The patent document with the prior publication number CN211951725U provides a wall and plate penetration prevention device for a water supply and drainage pipe in building engineering, which fixes a first ring, a first fixing plate and a second fixing plate by inserting a second fixing rod into a fifth inner groove, so that a first supporting rod below the first ring extrudes a sealing gasket, thereby improving the sealing performance around the drainage pipe. Although the device has more beneficial effects, the following problems still exist: the device need punch on concrete slab at the in-process of installation, and not only the installation is comparatively inconvenient, and at the in-process of drilling, can form the gap in the concrete, leads to the phenomenon that the infiltration appears in the concrete. In view of this, we propose a seepage-proofing device for water supply and drainage pipe plates in building engineering.
