Building underground pipe gallery waterproof structure

Abstract

The invention belongs to the technical field of underground pipe gallery waterproofing, and particularly relates to a building underground pipe gallery waterproof structure. The building underground pipe gallery waterproof structure comprises a connecting pipe sleeve and pipelines fixed to the two ends of the connecting pipe sleeve in a clamped mode; and the connecting pipe sleeve comprises an outer sealing layer and an inner sealing layer. Two connecting screw bases which protrude out of the connecting pipe sleeve and are symmetrically distributed are arranged on the connecting pipe sleeve; the connecting screw bases are used for being connected with two positioning nuts in a threaded mode, the sections of the positioning nuts are of a concave structure, positioning holes are formed in the bottom ends of the two sides of each positioning nut, and positioning shaft pins of a T-shaped structure are fixedly arranged at the ends of a pipeline; when the positioning nuts are installed, thetwo ends, provided with the positioning holes, of each positioning nut and the positioning shaft pins on the pipeline are placed in a cross shape, and then the positioning nuts are screwed in a rotating mode until the positioning holes in the positioning nuts and the positioning shaft pins are clamped and fixed; and by means of the connection between the positioning nuts and the connecting screw bases and the clamping and fixing between the positioning holes and the positioning shaft pins, the connecting position between the connecting pipe sleeve and the pipeline is more stable.

[0002] Underground pipe corridor is a public infrastructure formed by placing two or more pipelines in it. It is the direction of urban lifeline engineering infrastructure development. Pipe corridors are generally buried underground with more and more internal functions. There are also certain requirements for the service life of the structural design, and now the groundwater environment is becoming more and more complex, and the later use requires safety. During the construction of the underground pipe gallery, because there are gaps in the connection of the pipe gallery, if The waterproof performance is poor, and it is easy to cause water leakage, which will have a negative impact on the use of the underground pipe gallery, and will increase the maintenance cost in the later period

[0003] China Patent Network proposes a shield construction waterproof structure for underground pipe gallery (publication number is CN209586399U3). This patent aims at the gaps in the connection of the pipe gallery in the prior art. If the waterproof performance of the connection of the underground pipe gallery is poor , prone to water leakage, a multi-stage sealed waterproof connection structure is designed, which can effectively improve the waterproof performance of the joint of the pipe gallery through multi-stage sealing. However, in actual use, due to the connection pipe and the waterproof seal connection pipe The sleeves are all hollow circular tubular structures. After being sleeved together, after a long period of water erosion, they are prone to loosening due to thermal expansion and contraction, which reduces the sealing stability and shortens the service life.
