Abstract

The invention discloses a waterproof pipe gallery with good sealing performance. The waterproof pipe gallery comprises pipe bodies, pre-embedded connecting pieces and covering connecting pieces, a first connecting end and a second connecting end are arranged on the two sides of each pipe body respectively, every two adjacent pipe bodies can be spliced, a splicing seam is formed between the first connecting end of one pipe body and the second connecting end of the other pipe body, the pre-embedded connecting pieces are arranged on the two sides of each pipe body in a surrounding mode and comprise pre-embedded parts pre-embedded in the pipe bodies and plastic connecting parts stretching out of the outer sides of the pipe bodies, the covering connecting pieces are annular, plastic combining parts are arranged at the two ends in the axial direction of each covering connecting piece respectively, and the plastic combining parts can be connected with the plastic connecting parts in a hot melting mode so that the covering connecting pieces and the pre-embedded connecting pieces can seal the splicing seams. According to the structure, the covering connecting pieces are tightly attached to the joints of every two pipe bodies, water is not prone to seeping from the joints to the pipe bodies, and on the other hand, when the pipe bodies slightly move or are staggered, the covering connecting pieces have the good elastic deformation capacity and can be better attached to the joints, and the more stable waterproof effect is provided.

Description

technical field [0001] The invention belongs to the technical field of municipal underground engineering, in particular to a waterproof pipe gallery with good sealing performance. Background technique [0002] In today's urban infrastructure construction, the underground pipe gallery plays a vital role. The underground pipe gallery concentrates engineering pipelines such as power, communication, heating, water supply and drainage, and gas, which can effectively reduce the construction and laying of various engineering pipelines. In order to facilitate the manufacture and construction of the pipe gallery, a prefabricated pipe gallery appeared. This kind of pipe gallery is composed of several single-section pipe galleries. However, because of this combination, water seepage at the joints is prone to occur. Cause damage to engineering pipelines in the utility gallery. At present, in some pipe gallery technologies, as shown in the patent CN112343084A, waterproof fillers such as...
