Comprehensive pipe gallery adopting jetted ultrahigh-toughness cement-based composite material and construction method of comprehensive pipe gallery

Abstract

The invention discloses a comprehensive pipe gallery adopting a jetted ultrahigh-toughness cement-based composite material and a construction method of the comprehensive pipe gallery. The comprehensive pipe gallery is composed of a corrugated steel plate, the fiber mesh reinforced ultrahigh-toughness cement-based composite material and a concrete base; the corrugated steel plate is cold-bent to form an arch-shaped section, a fiber woven mesh is arranged on the surface, and effective connection between the corrugated steel plate and the fiber woven mesh is guaranteed through connecting pieces;the ultrahigh-toughness cement-based composite material is jetted on the corrugated steel plate by using a jetting device; and the fiber woven mesh is formed by weaving carbon fibers, glass fibers orthin steel wires in a criss-cross manner. According to the comprehensive pipe gallery structure, the cooperative stress between the ultrahigh-toughness material and the steel plate can be ensured, andthe excellent bearing performance is obtained; when the ultrahigh-toughness material is pulled, multiple fine cracks can be generated so that an internal steel plate and a complex soil environment can be effectively blocked, and the steel rust prevention effect is achieved; and the construction process is simple and efficient so that the construction period can be shortened, and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a comprehensive pipe gallery using sprayed ultra-high toughness cement-based composite materials and a construction method thereof. Background technique [0002] Urban underground comprehensive pipe gallery (abbreviated as comprehensive pipe gallery) refers to a public tunnel used to centrally lay out municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heat, and gas under the city. It is a modern, scientific, and Intensive urban infrastructure. The comprehensive pipe gallery solves the problems of dense overhead line network, repeated excavation of the road surface, and frequent pipeline accidents, which is conducive to ensuring the functions of urban infrastructure, beautifying the urban environment, and improving the quality of urban development and comprehensive carrying capacity. With the deepening of my count...

Problems solved by technology

However, due to the complex underground environment where the utility tunnel is located, it is easy to cause steel corrosion; in order to prevent steel corrosion, electroplating steel or laying waterproof materials will increase the structural cost

On the other hand, steel plates of smaller thickness are prone to buckling failure, increasing the risk of structural failure
