Underground tunnel pass-through bridge structure

Abstract

The invention discloses an underground tunnel pass-through bridge structure, which comprises an underground tunnel and a bridge, wherein the bridge comprises a bridge span, a bearing cap, a bridge pier and a pier abutment; the underground tunnel is arranged directly below the bridge span; the underground tunnel is consistent with the extension direction of the bridge span; and foundation piles arearranged at the bottom of the underground tunnel and the pier abutment. In the invention, the technical scheme avoids the underground tunnel from bypassing the bridge and crossing the river, reducesthe space occupation, thereby realizing the purpose of intensive land use, meanwhile, reduces the envelope construction area, reduces the earth excavation cost, and thus reduces the engineering cost.By setting up underground tunnels, including pedestrian tunnels, vehicle tunnels and pipe corridors, the traffic pressure on the bridge deck can be effectively alleviated, and the traffic efficiency and safety can be improved.

Description

technical field [0001] The invention relates to the technical field of infrastructure engineering, in particular to an underground tunnel crossing bridge structure. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In the traffic of modern cities, the flow of vehicles and people is relatively large, coupled with the slopes at both ends of the bridge, opening restrictions, etc., so that the passing capacity of the bridge is limited, the traffic will be affected during peak hours, and there are potential safety hazards. [0003] In order to solve the above problems, in the prior art, underground tunnels are set up upstream of the bridge, including underground pedestrian tunnels, underground vehicle tunnels, and underground pipe galleries, etc., to connect both sides of the river to disperse the flow of vehicles and pedestrians on the bridge deck, improve traffic efficiency a...

AI Technical Summary

Problems solved by technology

However, in the existing technology, the way of setting up underground tunnels upstream of the bridge increases the excavation area, maintenance facilities and project cost, and does not conform to the principle of intensive land use currently advocated
