Embodiment Construction

[0033] Attached below figure 1 ~8 describe the embodiment of the present invention in detail.

[0034] Such as Figure 1~2 As shown, a prefabricated steel-concrete composite pipe gallery with crack control and anti-corrosion is composed of prefabricated parts, cast-in-place ultra-high toughness cement-based composite material 2, and concrete base 3; prefabricated part 1 includes bottom prefabricated parts 1-1 There are two types of top prefabricated parts 1-2; the comprehensive pipe gallery structure is supported on the concrete base 3.

[0035] Such as figure 2 As shown, the horizontal section of the structure is assembled by two bottom prefabricated parts 1-1 and one top prefabricated part 1-2 to form an arched cross-section; the longitudinal direction of the structure is formed by continuously assembling the formed arched cross-sectional units to reach the length that meets the design requirements.

[0036] Such as Figure 3-1~3-2 , Figure 4-1~4-2 , Figure 5-1~5-2 ...

Abstract

The invention discloses a crack-control anti-corrosion prefabricated steel-concrete composite comprehensive pipe rack. A comprehensive pipe rack structure is formed by splicing composite prefabricatedparts through casting ultrahigh-toughness cement-based composite materials in place. Two bottom prefabricated parts and one top prefabricated part are transversely spliced to form an arch-shaped section of the structure, and the structure longitudinally achieves the length meeting the design requirement by continuously splicing formed arch-shaped section units; and the prefabricated parts adopt steel-concrete composite cross sections and are composed of profile steel arches, reinforced concrete plates and shear connectors, grooves are reserved in structural hogging moment areas on the reinforced concrete plates, and after the prefabricated parts are assembled, the ultrahigh-toughness cement-based composite materials are cast in place in the grooves, so that transverse and longitudinal connection between the prefabricated parts is achieved. The comprehensive pipe rack is excellent in structure bearing performance and high in assembly degree and has excellent crack control and anti-corrosion properties, and the structural cost is reduced by reasonably arranging the ultrahigh-toughness cement-based composite materials.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a crack-controlling and anti-corrosion assembled steel-concrete combined comprehensive pipe gallery. 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 country's urbanization process and t...
