[0002] During the construction of a house, the layout of pipelines is particularly important. Among them, the wall-piercing pipe is a weak link in the waterproof project. If not properly handled, it is very easy to cause water seepage, especially for the wall-piercing pipes in the basement.

[0003] In the installation process of the existing wall-piercing pipes, sleeves are usually pre-embedded first, and then the wall-piercing pipes are passed through the sleeves, and waterproof materials are filled between the wall-piercing pipes and the sleeves to achieve waterproofing. Although this method can achieve a certain waterproof effect, the waterproof structure is too single. As the service time increases, the waterproof materials will be continuously corroded by moisture and humidity, resulting in the gradual appearance of water seepage and leakage of the waterproof materials, and ultimately leading to the failure of the entire waterproof structure. For this reason, we propose a waterproof structure for a sleeve-type wall-piercing pipe. Content of the Utility Model
