Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when a traffic accident occurs in the underpass tunnel, sometimes the damaged vehicle will generate a large amount of thick smoke, or even ignite a flame, and the space under the tunnel is relatively airtight, making it difficult for the thick smoke to disperse , accumulated in the underpass tunnel, a large amount of thick smoke will cause secondary damage to the accident victims

Embodiment Construction

[0035] The following is attached Figure 1-5 The application is described in further detail.

[0036] The embodiment of the present application discloses a main line frame structure under which a road passes. refer to figure 1 , including a main line frame structure tunnel 1 passing under the road, an adsorption device 2 for absorbing dense smoke is arranged on the inner top wall of the tunnel 1, and multiple adsorption devices 2 are arranged along the length direction of the tunnel 1; The place where a traffic accident occurs in the tunnel 1 and produces dense smoke cannot be determined, so an adsorption device 2 is installed along the length of the tunnel 1, so that as long as a vehicle has a traffic accident and generates dense smoke, the adsorption device 2 in the tunnel 1 can be adsorbed. Thick smoke; an induction driving device 3 is also installed on the top wall of the tunnel 1, and the induction driving device 3 is used to drive the adsorption device 2 to approach ve...

Abstract

The invention relates to a road underneath pass main line frame structure. The road underneath pass main line frame structure comprises a tunnel, adsorption devices used for adsorbing dense smoke arearranged on the inner top wall of the tunnel, the multiple adsorption devices are arranged in the length direction of the tunnel, an induction driving device is further installed on the top wall of the tunnel, and the induction driving device is used for driving the adsorption devices to vertically get close to each other downwards and driving the adsorption devices to start adsorbing the smoke when sensing the smoke. The structure has the effect of reducing secondary harm of dense smoke to an accident victim to a certain extent.

Description

technical field [0001] The present application relates to the technical field of underpassing tunnels, in particular to a frame structure for underpassing main lines of roads. Background technique [0002] With the rapid development of highway traffic in our country, unprecedented achievements have been made in the field of highway tunnels. More and more tunnels with ultra-shallow burial, large cross-section, and passing through structures are appearing in actual projects. For the construction method of ultra-shallow buried large-section tunnels, the majority of scientific and technological workers have carried out a lot of research and achieved a lot of results. [0003] The original intention of the design of the underpass tunnel road in the related art is to better solve the problem of traffic congestion, greatly utilize the road area, and realize more vehicle diversion. [0004] In view of the above-mentioned related technologies, the inventor believes that when a traf...
