Reinforced concrete combined double-layer hazardous rock falling protection hangar tunnel

Abstract

The invention discloses a reinforced concrete combined double-layer hazardous rock falling protection hangar tunnel. The tunnel comprises a reinforced concrete hangar tunnel body, wherein the hangar tunnel body is connected to a main beam of a bridge, a plurality of steel frameworks are arranged at intervals on a top plate of the hangar tunnel body in the longitudinal direction of the bridge, thetwo sides of each steel framework are connected to the top plate through vibration reduction components, the every two adjacent steel frameworks are connected through a plurality of steel cross connectors, and all the steel frameworks are connected with flexible protective nets. The reinforced concrete combined double-layer hazardous rock falling protection hangar tunnel is simple in structure, the characteristics of the impact resistance and light weight of an upper layer structure and the characteristics of good durability and maintenance omission of a lower layer structure are fully exerted, so that the whole structure has the characteristics of good impact resistance, easy maintenance and no influence on travelling during maintenance.

Description

technical field [0001] The invention relates to a shed cave, in particular to a steel-concrete composite double-layer dangerous rockfall protection shed cave. Background technique [0002] Hazardous rockfall disasters are a common type of geological disasters in alpine and valley areas (especially high-intensity areas) around the world. Such as roads, bridges, tunnel entrances, etc.) and human activities (driving vehicles, passing people, etc.) constitute a serious threat. [0003] The shed tunnel is the last line of defense applied above railways and highways to prevent the hazards of dangerous rocks and falling rocks. The traditional protective shed holes are mainly reinforced concrete shed holes, which include open hole type, frame type, cantilever type, etc. In addition, there are steel frame shed holes, light steel flexible shed holes and other new types of shed holes. Among them, the reinforced concrete shed is the most widely used, and its foundation is generally se...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to overcome the difficulty in foundation construction when traditional shed tunnels are used for bridges in mountainous areas in the prior art and the foundation volume is huge, the structural risk is multiplied, it is not conducive to the operation of personnel and machinery and equipment, and the requirements for construction machinery and equipment are also greatly increased , safety risks for construction personnel, long construction period, temporary road construction, and poor economic efficiency. A steel-concrete combination double-layer dangerous rockfall protection shed is provided.
