Buried pipeline through-wall waterproof device and installation method

Abstract

The invention relates to a buried pipeline through-wall waterproof device and an installation method.The buried pipeline through-wall waterproof device comprises a flexible sealing sleeve arranged on a buried pipeline in a sleeving mode, the buried pipeline penetrates through an outer wall of an underground building structure, and the flexible sealing sleeve is a conical sleeve and is located in the underground building structure; the large head end of the flexible sealing sleeve is fixedly connected with a connecting piece on an outer wall in a sealed mode through a wall body sealing ring, the small head end of the flexible sealing sleeve is fixedly connected with a buried pipeline in a sealed mode, a telescopic joint formed through folding is arranged in the middle of the flexible sealing sleeve, and the device has the advantages of being simple in structure, low in cost, good in waterproof effect, convenient to inspect and maintain and high in practicability; the mounting method has the advantages of simple process, high working efficiency, safety and reliability.

Description

technical field [0001] The invention relates to a sealing waterproof device, in particular to a buried pipeline through-wall waterproof device suitable for an underground building structure and an installation method. Background technique [0002] A large number of underground building structures are built in modern cities, and various functional pipes of such underground building structures are generally arranged through the outer walls and buried underground. In order to prevent outdoor water from entering the room along the buried pipeline, the current field usually adopts the method of filling waterproof material between the buried pipeline and the wall (or wall casing) for waterproofing, although this method can achieve basic waterproofing. However, there are the following problems in practical application: 1. After a period of use, water leakage is likely to occur due to thermal expansion and cold contraction, which affects safety; 2. It is not easy to check and block ...

In order to prevent outdoor water from entering the room along the buried pipeline, the current field generally adopts the method of filling waterproof material between the buried pipeline and the wall (or wall casing) for waterproofing, although this method can achieve basic waterproofing. purpose, but there are the following problems in practical application: 1. After a period of use, water leakage is easy to occur due to thermal expansion and contraction, which affects safety; 2. It is not easy to check and block after water leakage occurs, and The maintenance process is cumbersome, the maintenance cost is high, and it is difficult to achieve long-term plugging effect
