Composite material reinforcing special-shaped mortise and tenon self-fastening-type duct pieces for underground pipe galleries

Abstract

The invention discloses a composite material reinforcing special-shaped mortise and tenon self-fastening-type duct pieces for underground pipe galleries. The composite material reinforcing special-shaped mortise and tenon self-fastening-type duct pieces for main underground pipe galleries, multi-body galleries, branch galleries and main subsidiary gallery bodies are jointly composed of duct piececonnecting tapered planes, high-performance concrete, concave mortise and tenon joint faces, longitudinal basalt fiber composite material reinforcing ribs, concave mortise and tenon stress slopes, convex mortise and tenon joint faces, convex mortise and tenon composite material reinforcing ribs, convex mortise and tenon stress slopes, convex mortise and tenon concrete and arc composite material reinforcing ribs. The composite material reinforcing special-shaped mortise and tenon self-fastening-type duct pieces for the underground pipe galleries replace duct pieces with reinforced steel materials and reinforced concrete and for the underground pipe galleries, the problem that the service life of main underground pipe gallery bodies is short due to the ubiquitous phenomena of corrosion of duct pieces with steel fastening parts and reinforced concrete and for the pipe galleries, and disassembly of duct pieces with expansive concrete is solved, the safety and reliability of long-term use of the underground pipe galleries are improved, the maintenance and replacement period of the underground pipe gallery bodies is prolonged, and the service life of the main underground pipe gallery bodies is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of underground construction, and specifically relates to a composite material rib-reinforced special-shaped mortise and tenon self-fastening underground pipe gallery with various specifications and models of the main gallery, multi-body gallery, branch gallery, and sub-corridor main body. Background technique [0002] The underground pipe gallery is a city that integrates all facilities such as water supply, drainage, heating, gas, electricity, and communication. If the design and materials are reasonable, it can reduce urban operating costs. [0003] At present, the underground pipe gallery is generally constructed of reinforced concrete materials and connected with steel materials. Due to the corrosion and expansion of the steel bars and steel materials in the main body of the concrete underground pipe gallery, the main body of the concrete pipe gallery is cracked and the potential safety hazards of the pipe gallery ...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is: the corrosion and expansion of steel connecting materials and steel bars break the main body of the concrete pipe gallery, resulting in the short service life of the underground pipe gallery

The composite material basalt fiber bars adopted in the present invention have a service life twice that of steel bars, a tensile strength three times that of steel bars, never rust, and a long-term use cost of only half of the steel bars, replacing the reinforced concrete underground reinforced by steel materials The pipe gallery segment completely solves the problem that the steel fastened underground pipe gallery segment and the reinforced concrete pipe gallery segment are easy to corrode, expand and cause concrete disintegration, resulting in short service life of the main body of the underground pipe gallery
