Problems solved by technology

[0003] Existing highway tunnels with two-way lanes usually include a cave body and a clapboard vertically arranged in the middle of the cave body. The main purpose of the clapboard is to prevent traffic accidents from occurring when driving in two directions. support force, thereby improving the strength of the entire cave body, the existing partitions are poured in the cave body by the method of pouring in situ, and the method of pouring in situ reduces the construction efficiency of the partition construction

Abstract

The invention relates to a two-way highway tunnel blocking and supporting structure which comprises a tunnel body, a plurality of prefabricated bottom plates are arranged in the tunnel body and located on the bottom wall of the tunnel body, the multiple bottom plates are arranged in the length direction of the tunnel body, and a plurality of prefabricated top plates are arranged in the tunnel bodyand located on the top wall of the tunnel body. The multiple top plates are arranged above the multiple bottom plates in a one-to-one correspondence mode, prefabricated partition plates are arrangedbetween the bottom plates and the top plates, each partition plate comprises a plurality of connecting plates arranged in the height direction of the tunnel body, and first connecting pieces used fordetachably connecting the partition plates to the bottom plates are arranged on the bottom plates. The top plates are provided with second connecting pieces used for detachably connecting the partition plates to the top plates, and the adjacent connecting plates are provided with third connecting pieces used for detachably connecting the adjacent connecting plates together. The two-way highway tunnel blocking and supporting structure has the advantage that the construction efficiency of the two-way highway tunnel blocking and supporting structure is improved.

Description

technical field [0001] The application relates to the field of highway construction, in particular to a barrier support structure for a two-way highway tunnel. Background technique [0002] Highway tunnels are passages built underground for cars to travel, and generally also serve as passages for pipelines and pedestrians. The main building of the road tunnel is generally composed of the tunnel body, lining and portal, and an open tunnel is also built in the section where the tunnel entrance is prone to collapse. The auxiliary structures of the tunnel include waterproof and drainage facilities, ventilation and lighting facilities, traffic signal facilities and emergency facilities. [0003] Existing highway tunnels with two-way lanes usually include a cave body and a clapboard vertically arranged in the middle of the cave body. The main purpose of the clapboard is to prevent traffic accidents from occurring when driving in two directions. Supporting force, thereby improvin...
