Waterproof and shock-absorbing system device and installation method of prefabricated rectangular comprehensive pipe gallery interface

Abstract

The invention provides a waterproof cushioning system device of a prefabricated rectangular comprehensive pipe rack connector and a mounting method of the waterproof cushioning system device, and belongs to the technical field of underground structure comprehensive pipe racks. The waterproof cushioning system device of the prefabricated rectangular comprehensive pipe rack connector comprises a segment jack part and a segment socket part which are connected correspondingly; the segment jack part comprises a first vertical part, a first oblique part and a second vertical part, and the segment socket part comprises a third vertical part, a second oblique part and a fourth vertical part; the first oblique part is provided with one or more wedge grooves, U-like rubber blocks are arranged in thewedge grooves, and the surfaces of the U-like rubber blocks are glued with water-swelling rubber layers; and the segment jack part and the segment socket part are connected through a plurality of damping bolts, and a waterproof storage system is arranged in a seam between the first vertical part and the third vertical part. According to the waterproof cushioning system device of the prefabricatedrectangular comprehensive pipe rack connector and the mounting method of the waterproof cushioning system device, a water flow can be effectively prevented from entering a comprehensive pipe rack bin, the service life period of the waterproof cushioning system device is prolonged, safety performance of the waterproof cushioning system device is improved, and the stable operating capacity of the connector is improved.

Description

technical field [0001] The invention relates to the technical field of underground structure comprehensive pipe gallery, in particular to a waterproof and shock-absorbing system device for the interface of a prefabricated rectangular comprehensive pipe gallery and an installation method thereof. Background technique [0002] In the construction of urban underground utility tunnels, segment interface is one of the weak links in the design and construction of utility tunnels, which has long plagued the operation and promotion of utility tunnels. In recent years, with the vigorous development of urbanization, the tension of urban land has been aggravated. Due to its advantages in wiring, space utilization, and convenient maintenance and operation, the rectangular section is much better than the circular section. The prefabricated rectangular integrated pipe Corridors are quickly used in underground comprehensive pipe gallery projects all over the country. However, compared with...

Problems solved by technology

[0003] In order to solve the technical problems of the prior art, such as the short interface size of the interface of the prefabricated rectangular integrated pipe gallery, difficulty in setting up water stop devices, low water blocking performance, poor integrity of the prefabricated structure, and weak shock absorption function, the present invention provides a prefabricated rectangular integrated pipe gallery. The waterproof cushioning system device of the pipe gallery interface and its installation method, in the socket interface with an inclined slope, the U-shaped rubber block and the annular rubber tube of the water-expandable rubber layer bonded on the surface can prevent the water flow from entering the complex to the greatest extent. In the pipe gallery cabin, prevent water from causing adverse effects on the pipe gallery, use shock-absorbing bolts to connect, improve the service life and safety performance of the structure, and improve the smooth operation ability of the interface
