Description
Technical field
The present invention relates to Tunnel Engineering fields, and in particular to a kind of tunnel inverted arch filling discharge structure.
Background technology
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 because one of be tunnel water handling structure failure lead to tunnel bottom ponding.
In recent years, be designed with 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 both sides.In this scheme, lateral sulcus accepts what tunnel circumferential direction blind pipe collected with longitudinal blind pipe
Infiltration drains into tunnel outer.The program is only drained by lateral sulcus 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, the centrally disposed drainpipe in tunnel is arranged in tunnel both sides, 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 with central drainage pipe by PVC aqueducts, water is led into central drainage pipe and is drained into outside tunnel.The program can be by tunnel
Superstructure infiltration smoothly discharge, 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, the centrally disposed drainpipe in tunnel is arranged in tunnel both sides, 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 aqueducts are 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.
Invention content
For the above-mentioned technical problems in the prior art, the present invention provides a kind of tunnel inverted arch to fill draining knot
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 by the present invention is：A kind of tunnel inverted arch filling discharge structure, including set
It is convex to be placed in inverted arch fill surface longitudinal convex hull formula drain bar below, lateral convex hull formula drain bar and centre drain, the longitudinal direction
Shell-type drain bar totally three, is respectively arranged on the outside of left and right line circuit and tunnel midline position, the transverse direction convex hull formula drain bar
It is set at each circular construction joint, the longitudinal direction convex hull formula drain bar is located at same level, institute with lateral convex hull formula drain bar
Centre drain is stated to be set under longitudinal convex hull formula drain bar of tunnel midline position on inverted arch.
Further, longitudinal convex hull formula drain bar is located at inverted arch fill surface or less 0.3- with lateral convex hull formula drain bar
At 0.6m.
Further, longitudinal convex hull formula drain bar and lateral convex hull formula drain bar width are 30~100cm.
Further, inspection shaft both 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 present invention has the following effects that：By the way that longitudinal convex hull formula row is arranged inside being filled in inverted arch
Water plate and lateral convex hull formula drain bar, the underground water that construction joint is leaked out import centre drain, it is ensured that and inverted arch fills drying,
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, can also effectively prevent
The freeze injuries such as tunnel bear building-up ice, tunnel bottom frost heave protuberance.
