Embodiment Construction

[0015] like figure 1 Shown: A prefabricated pipe joint of a comprehensive pipe gallery, which is composed of a regular trapezoidal segment structure and an inverted trapezoidal segment structure.

[0016] like figure 2 Shown: positive trapezoidal segment structure 1, the width of the bottom opening is 2.5m~3.0m (the standard section width can be adjusted appropriately according to the actual situation), the width of the upper opening is 1.5~2.0m, and there are protrusions 31 around the fracture. The mouth 31 is shaped on a waterproof rubber strip mounting groove 4, the mounting grooves 4 on both sides are positioned at the front of the convex hole 31, and the upper and lower mounting grooves 4 are positioned at the top surface of the convex hole 31. like Figure 4 As shown: the groove bottom 5 with rounded corners is set at the junction of the mounting grooves 4 on both sides and the upper and lower mounting grooves 4 for transitional treatment. Reserve hoisting bolt holes...

Abstract

A prefabricated type pipe joint of a comprehensive pipe gallery comprises erected trapezoidal segment structures and inverted trapezoidal segment structures. Convex openings are made around fracturesof the erected trapezoidal segment structures; waterproof rubber strip mounting grooves are made around the convex openings; the mounting grooves on the two sides are located in the front faces of theconvex openings, and the upper and lower mounting grooves are located in the top faces of the convex openings; hoisting bolt holes are reserved in the tops of the side walls of the two sides of the erected trapezoidal segment structures; notches are formed around the inverted trapezoidal segment structures; and the convex openings of the erected trapezoidal segment structures and the notches of the inverted trapezoidal segment structures are in Z-shaped tongue-and-groove connection in the mounting process. Lateral extrusion force and vertical extrusion force are generated directly through theshapes and the weights of the structures in the vertical mounting process to extrude waterproof rubber strips, so that the water-stopping and waterproof purposes are achieved. Meanwhile, the waterproof rubber strips can be mounted immediately after engineering prefabricating, accordingly, the mounting efficiency is improved, the on-site mounting procedures are reduced, and the construction cost is reduced.

Description

Technical field: [0001] The invention belongs to a device for construction of an urban underground pipe network system, in particular to a prefabricated pipe joint of a comprehensive pipe gallery. Background technique: [0002] As the country promotes the construction of urban underground comprehensive pipe gallery, urban pipe gallery projects have grown rapidly, and the construction technology of pipe gallery has also developed rapidly. There are more and more projects. It is a new comprehensive pipe gallery construction method that prefabricated pipe joints in the factory and assembled on the construction site. [0003] The existing prefabricated urban comprehensive pipe gallery mostly adopts the connection mode of reinforced concrete structure ring socket and groove. When the prefabricated segment structure is hoisted and installed, it is first hoisted vertically to the design elevation, then with the assistance of manpower, it is inserted horizontally, and finally the p...
