Background

The wall-through pipe is also called a wall-through sleeve, a waterproof sleeve, a wall-embedded pipe and the like, is installed through a wall, and is an important device for water supply and drainage engineering of buildings. When the wall pipe is of a single-layer structure, water flows in the wall pipe, so that high noise is generated, and normal rest of residents is influenced. In order to reduce noise, most of the existing wall pipes adopt a double-layer structure, namely, an outer pipe is sleeved outside an inner pipe, and a noise reduction material is filled between the inner pipe and the outer pipe, so as to achieve the purposes of reducing noise and eliminating noise. However, the existing wall pipes are fixed in length, and when a wall body needing to be penetrated is thick, a joint structure is usually adopted to connect a plurality of silencing wall pipes into an integral structure so as to meet the actual installation requirement. For example, in a noise-reducing and silencing wall pipe for water supply and drainage in a building disclosed in patent document No. CN211779456U, a plurality of noise-reducing wall pipes can be connected by using the noise-reducing wall pipe and the joint structure disclosed therein.
