Description
Technical field
The utility model relates to Tunnel Engineering fields, and in particular to a kind of tunnel inverted arch filling discharge structure.
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 the failure of tunnel water handling structure 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 tunnel inverted arch filling draining
Structure effectively reduces tunnel bottom disease odds to solve the ponding of tunnel inverted arch.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of tunnel inverted arch filling discharge structure, packet
It includes and is set to inverted arch fill surface longitudinal convex hull formula drain bar, lateral convex hull formula drain bar and centre drain below, it is described vertical
It to convex hull formula drain bar totally three, is respectively arranged on the outside of left and right line route and tunnel midline position, the transverse direction convex hull formula row
Water plate is set at each circular construction joint, and the longitudinal direction convex hull formula drain bar and lateral convex hull formula drain bar are located at same water
Flat, the centre drain is set under longitudinal convex hull formula drain bar of tunnel midline position on inverted arch.
Further, longitudinal convex hull formula drain bar and lateral convex hull formula drain bar are located at inverted arch fill surface or less 0.3-
At 0.6m.
Further, longitudinal convex hull formula drain bar and lateral convex hull formula draining board width are 30~100cm.
Further, inspection shaft two sides are provided with drain hole, for arranging longitudinal convex hull formula drain bar and lateral convex hull formula
The water that water plate collects introduces centre drain.
Compared with prior art, the utility model has the following effects that：By the way that longitudinal convex hull is arranged inside inverted arch is filled
Formula drain bar and lateral convex hull formula drain bar, the underground water that construction joint is leaked out import centre drain, it is ensured that inverted arch filling
It is dry, the probability that the diseases such as rise soil, tunnel bottom is swelled occurs in tunnel bottom can be effectively reduced.In addition, in severe cold area, it can also be effective
Prevent the freeze injuries such as tunnel bear building-up ice, tunnel bottom frost heave protuberance.
