Embodiment Construction

[0032] Attached below Figure 1~6 , to describe the implementation of the present invention in detail.

[0033] Such as figure 1 As shown, a prefabricated integrated pipe gallery using ultra-high toughness cement-based composite materials includes the following components: prefabricated parts, including two forms: bottom prefabricated part 1-1, top prefabricated part 1-2; super high toughness The connecting layer 2 formed by cast-in-place cement-based composite materials; the concrete base 3 .

[0034] Such as figure 1 , figure 2 As shown, the comprehensive pipe gallery structure is composed of prefabricated parts, a connecting layer 2 formed by cast-in-place ultra-high toughness cement-based composite materials, and a concrete base 3; figure 2 As shown, the preforms include a bottom preform 1-1 and a top preform 1-2. The processing of prefabricated parts is completed in the factory and transported to the construction site for assembly.

[0035] Such as Figure 1~2 As...

Abstract

The invention discloses a prefabricated assembly type comprehensive pipe gallery adopting ultrahigh-toughness cement-based composite materials and an assembly method of the prefabricated assembly typecomprehensive pipe gallery. The comprehensive pipe gallery is structurally composed of prefabricated parts, the cast-in-place ultrahigh-toughness cement-based composite materials and a concrete base.For the comprehensive pipe gallery structure, two bottom prefabricated parts and one top prefabricated part are spliced to form an arch-shaped section, the ultrahigh-toughness cement-based compositematerials are cast in place at the connecting position, and the prefabricated parts are composed of corrugated steel plates, the ultrahigh-toughness cement-based composite materials and shear connectors. According to the comprehensive pipe gallery structure, the ultrahigh-toughness cement-based composite materials outside the corrugated steel plates remarkably improve the bearing performance of the structure, and an anti-corrosion role in blocking the complex environment of external soil is also achieved; the prefabricated parts are transported to the site after being completely machined in afactory, so that industrial integration is easy, and the machining precision and quality of the prefabricated parts are guaranteed; and fabricated construction and a small amount of cast-in-place workare conducted on a construction site, so that the construction period is shortened, and the cost is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a prefabricated integrated pipe gallery using ultra-high toughness cement-based composite materials and an assembly 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...
