Technical Field

[0001] The utility model relates to a casing anti-leakage device for an exterior wall of a building, belonging to the technical field of building construction equipment. Background Art

[0002] During the construction process, the pre-buried sleeves on the exterior wall are used for the subsequent installation of water and electricity pipes. After the sleeves on the exterior wall are pre-buried, holes will be left, and water outside the wall can easily penetrate into the room through the holes. Especially in the rainy season when there is a lot of precipitation, if the holes in the exterior wall sleeves cause water to seep into the basement, it will cause a lot of economic losses.

[0003] Before installing pipes or laying cables, the traditional sealing method for exterior wall casings is generally mud filling or blind plate sealing. However, this sealing method is easily damaged by the impact of rainwater accumulated on the exterior wall, which reduces the tightness of the sealing and causes accumulated water to leak into the indoor environment, thereby reducing the quality of construction.
