Description
Technical field
The utility model relates to Tunnel Engineering fields, and in particular to a kind of full packet pressure release waterproof/drainage structure in tunnel.
Background technique
A large amount of tunnel bottoms disease that China railways tunnel occurs, including rise soil, tunnel bottom protuberance, tunnel bottom frost heave etc., cause
Cause of disease is therefore first is that tunnel waterproof and water drainage system failure leads to tunnel bottom ponding.
In recent years, design has the railway tunnel bottom drainaging scheme of inverted arch by continuing to optimize and improveing, it is main comprising with
Under it is several:
1, lateral sulcus only is set in tunnel two sides.In this scheme, lateral sulcus accepts what circumferential direction blind pipe in tunnel collected with longitudinal blind pipe
Infiltration drains into tunnel outer.The program only passes through lateral sulcus and drains to outside tunnel, and drainage speed is limited, if tunnel superstructure seeps water
Amount is big, it is possible to cause sprawling of the water into tunnel, and tunnel inverted arch bottom ponding can not be by ejectment.Taizhongyin railway, north Huang
Rail segment tunnel uses such scheme.
2, lateral sulcus is arranged in tunnel two sides, and drainpipe is arranged in tunnel center, and central drainage pipe is placed in inverted arch fill concrete.
In this scheme, lateral sulcus accepts the infiltration that tunnel circumferential direction blind pipe and longitudinal blind pipe collect and a part is drained into tunnel outer, simultaneously
It is connected by PVC aqueduct with central drainage pipe, water is led into central drainage pipe and is drained into outside tunnel.The program can be by tunnel
Superstructure infiltration is smoothly discharged, but tunnel inverted arch bottom ponding cannot be by ejectment.Shanxi middle and south rail channel is covered west to China
Tunnel tunnel bottom in middle rail channel part uses such scheme.
3, lateral sulcus is arranged in tunnel two sides, and drainpipe is arranged in tunnel center, and central drainage pipe is placed in inverted arch structural base.This side
In case, lateral sulcus accepts the infiltration that tunnel circumferential direction blind pipe and longitudinal blind pipe collect and a part is drained into tunnel outer, and lateral sulcus passes through
PVC aqueduct is connected with central drainage pipe inspection shaft, can lead to water in inspection shaft and be drained into outside tunnel by central drainage pipe,
Be laid with and Permeable blind pipe and be connected in central drainage pipe inspection shaft in inverted arch bottom simultaneously, can by inverted arch bottom ponding and circumferential direction and
Longitudinal blind pipe part ponding is collected to inspection shaft and is discharged by central drainage pipe.The program can be by tunnel inverted arch bottom ponding
Smooth ejectment, but in the preferable location of Grades of Surrounding Rock, tunnel bottom central drainage pipe foundation trench excavates difficulty, and it is difficult to increase construction
Degree.Zhangjiakou to Huhehaote railway, Jilin to Hunchun railway engineering, nine visitor of force specially use in Ruichang to Jiujiang rail segment tunnel
Such scheme.
Utility model content
For the above-mentioned technical problems in the prior art, the utility model provides a kind of complete anti-row of packet pressure release in tunnel
Water-bound, it can either prevent the underground water of tunnel outer from entering tunnel, while can also eliminate the water pressure on tunnel structure.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows: a kind of full packet pressure release waterproof/drainage structure in tunnel,
Tunnel vault, abutment wall and inverted arch including full closed waterproof, tunnel-liner ecto-entad successively include preliminary bracing injection coagulation
Soil, non-woven fabrics, convex hull formula drain bar, EVA splash guard and two linings are molded into concrete;The draining of tunnel bottom is embedded with below the inverted arch
Pipe, inverted arch arrangement above have inverted arch drainpipe, and the inverted arch drainpipe is connect with tunnel floor drain by communicating pipe.
Further, the tunnel floor drain diameter is determined according to Tunnel Seepage, generally 400~1000mm.
Further, the inverted arch draining pipe diameter is 200~500mm.
Further, the communicating pipe longitudinal pitch is 30~50m.
Further, inverted arch drainpipe periphery is filled using rubble or cobble, and tunnel floor drain periphery is using permeable
Concrete package.
The utility model has the beneficial effects that the utility model uses EVA splash guard full closed waterproof, underground can be effectively prevent
Water enters tunnel internal, prevents tunnel bottom from ponding occur, reduce tunnel bottom rise soil, the diseases such as tunnel bottom protuberance, tunnel bottom frost heave
Probability;The underground water of tunnel perimeter is discharged into tunnel floor drain with convex hull formula drain bar, prevents tunnel lining structure from water occur
Pressure reduces the load of tunnel structure, and can also effectively prevent tunnel-liner behind in severe cold area causes because there is ponding
Freeze injury problem.
