Self-adaptive replaceable pipeline joint waterproof structure

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a self-adaptive replaceable pipeline joint waterproof structure. The self-adaptive replaceable pipeline joint waterproof structure comprises two water stopping units, and each water stopping unit comprises a first steel component and a second steel component which are respectively embedded into the socket end of a pipeline joint and the female end of the pipeline joint; grooves are formed in the contact surfaces of the first steel components and the second steel components and on the contact surfacesof the second steel components and the second steel components correspondingly, the grooves of the first steel components and the grooves of the second steel components correspond to each other to form cavities, and a rubber air bag is arranged in each cavity; inflation holes corresponding to the rubber air bags are formed in the socket end of the pipeline joint and the first steel components; and a detection hole is formed in the socket end of the pipeline joint or the female end of the pipeline joint between the two rubber airbags. The steel components in the two water stopping units are arranged on one side of the inner side of the pipeline joint, so that the replacement of the rubber air bags in the water stopping units is realized, and the long-acting requirement for the waterproof performance of the pipeline joint is met.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an adaptive and replaceable waterproof structure of a pipe joint. Background technique [0002] Reinforced concrete pipes have been widely used in municipal engineering in my country. In recent years, with the rapid development of urban underground comprehensive pipe gallery construction in China, large-diameter reinforced concrete pipes have been given a brand-new construction form as an underground comprehensive pipe gallery. vitality. As the new "lifeline" of the city, the underground comprehensive pipe gallery has high requirements for its own waterproof performance. However, the waterproof structure at the joints of the existing large-diameter reinforced concrete pipes is mainly sealed with rubber rings, which is difficult to cope with the service life of the pipes. With the increase of years, the problem of waterproof failure of pipe joints caused by t...
