Problems solved by technology

However, since these two methods do not have the effect of applying precompressive stress on the pipe gallery unit to improve the stiffness of the pipe gallery unit at the interface, there is little positive significance for preventing the pipe gallery unit from creating gaps at the interface for a long time
[0006] The applicant has searched the literature, but there is no technical revelation that can effectively solve the sealing problem between the pipe gallery units in the published Chinese and foreign patents and non-patent literature so far. The technical solution to be introduced below is based on this generated in the background

Abstract

A prefabricated pipe gallery prestressed gasket belongs to the technical field of pipeline seals. It includes a sealing gasket main body, and is characterized in that it also includes a prestressing mechanism, which is arranged around the sealing gasket main body and wrapped by the sealing gasket main body. Due to the use of the prestressed mechanism wrapped by the main body of the gasket, it helps to permanently seal the interface of adjacent pipe gallery units, avoiding gaps and leakage in the pipe gallery over time.

Description

technical field [0001] The invention belongs to the technical field of pipe seals, and in particular relates to a prestressed sealing gasket for a prefabricated pipe gallery. Background technique [0002] The aforementioned prefabricated pipe gallery is also called prefabricated pipe gallery, prefabricated integrated pipe gallery or underground comprehensive pipe gallery. It has the following advantages: because the prefabricated pipe structure is the main body, it can significantly reduce material consumption; It has strong corrosion ability, so it can reflect a good service life; because it can realize standardized and factory prefabricated production and is not affected by the natural environment, it can fully guarantee the quality of prefabricated parts and meet the requirements of industrial scale-up production; On-site assembly is implemented after the site, so the construction efficiency is high, which helps to save construction costs; it can not only ensure the accur...
