Integral structure of bridge and underground pipe gallery and its construction method

Abstract

The invention discloses a bridge and underground pipe gallery integral structure and a method for constructing the same. The bridge and underground pipe gallery integral structure comprises a T beam, cover beams and upright columns. The upright columns are directly connected with an underground pipe gallery structure to form an integral structure, the underground pipe gallery structure comprises underground pipe gallery reinforcement sections and underground pipe gallery standard sections, the underground pipe gallery reinforcement sections are respectively connected with the underground pipe gallery standard sections and the upright columns, and a plain concrete cushion is arranged on the lower portions of the underground pipe gallery reinforcement sections and the lower portions of the underground pipe gallery standard sections. The bridge and underground pipe gallery integral structure and the method have the advantages that characteristics of bridges and underground pipe galleries are fused with one another by the bridge and underground pipe gallery integral structure, the bridge and underground pipe gallery integral structure is constructed by the aid of prefabricated assembly type construction processes, accordingly, the quality of concrete members can be improved, urban roads can be prevented from being secondarily excavated, the ground road occupation time during construction can be greatly shortened, the ground road occupation widths during construction can be greatly reduced, the quantity of cast-in-place concrete can be greatly reduced, the feasibility of the prefabricated members during transporting and hosting can be guaranteed, noise and blown dust pollution in construction periods can be effectively decreased, and the bridge and underground pipeline gallery integral structure and the method have excellent engineering economic benefits and social and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an integral structure of a bridge and an underground pipe gallery and a construction method thereof. Background technique [0002] Domestic large and medium-sized cities are building large-scale urban expressway systems to ease traffic and improve driving efficiency, and these expressways are mostly viaducts. So far, there are a large number of urban expressway viaducts that have been built in China. [0003] In recent years, with the increasing awareness of the comprehensive utilization of domestic municipal facilities, various places are vigorously developing underground pipe corridors, striving to reduce the damage to the urban environment during the laying of municipal pipelines and realize the intensive use of resources. [0004] However, judging from the current experience of municipal construction in domestic cities, urban expressway viaducts and underground...

AI Technical Summary

Problems solved by technology

[0004] However, judging from the current experience of municipal construction in domestic cities, urban expressway viaducts and underground pipe gallery projects are mostly carried out relatively independently, without consideration of system engineering, and usually require secondary excavation on urban ground roads, or even more This excavation will cause the project to occupy the road for a long time and the width of the temporary fence to occupy the road will be large, which will seriously affect the urban traffic and the ecological environment along the line, and will easily cause a lot of social repercussions
