After the rock mass above the tunnel uphill slope is broken and weathered, dangerous rock falling is easily formed, and the railway operation safety is seriously influenced. Generally, in order to ensure the driving safety of a train and protect the tunnel portal and the connected bridge from falling rocks, a bridge protection shed tunnel needs to be arranged above the tunnel portal.
The bridge protection shed tunnel can be divided into a rigid shed tunnel and a flexible shed tunnel. The flexible shed tunnel is usually formed into a flexible protective structure system by adopting devices such as steel supports, energy dissipation flexible nets and the like, and has the characteristics of convenience in installation, low cost, easiness in replacement and the like. However, the flexible shed tunnel mainly adopts a steel structure, so that the stability of resisting train vibration is weak, and the corrosion resistance and the durability are poor. At present, the domestic rigid shed tunnel is widely used. As shown in fig. 1-2, the rigid bridge protection shed tunnel is made of a reinforced concrete frame structure, usually in a structural form of "frame + beam", the beam 3 mainly bears the impact load of falling rocks and disperses the impact load to the frame structures 2 at two sides, and the frame structures 2 mainly play a role in supporting the beam 3 and transmitting the self weight of the beam and the impact load of falling rocks downwards, so that the bridge 1 below the shed tunnel can be protected. The cross section of the cross beam 3 can be rectangular or T-shaped, after the cross beam 3 is paved, the buffering and water-resisting layer 4 is paved at the top of the cross beam 3, the buffering and water-resisting layer 4 can be a gravel buffering layer and a clay water-resisting layer, and the bottom of the buffering and water-resisting layer 4 is provided with drain holes 5 at intervals of 3-5 m along the longitudinal direction of the line.
When the rigid shed tunnel top is designed integrally, once the shed tunnel top is hit by falling rocks and the cross beam 3 is damaged during operation, the repair of the shed tunnel is very difficult. After the cross beam 3 is damaged, the buffer and water-resisting layer 4 at the top of the integral shed tunnel needs to be removed, the beam pieces of the cross beam 3 can be disassembled and replaced, the buffer and water-resisting layer 4 needs to be laid again after the disassembly and replacement are finished, the maintenance and replacement time is long, and the work efficiency is low.
