Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] see figure 1 , figure 2 and image 3 As shown, the present embodiment is an underground tunnel crossing bridge structure, including an underground tunnel 1 and a bridge 2, and the bridge 2 includes a span 3, a cap 4, piers 5 and abutments 6, and the underground tunnel 1 is arranged on the bridge span 3 Directly below, the extension direction of the underground tunnel 1 and the bridge span 3 is the same. The space at the bottom of the bridge 2 is u...

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...
