Description
Technical field
The utility model is related to tunnel drainage system, and more particularly to one kind can the outer draining system of maintenance type railway tunnel bottom structure
System.
Background technology
The drainage system of current double -coil output is main to be led by ring blind pipe, longitudinal blind pipe, inlet opening, lateral sulcus, transverse direction
Water pipe, central drainage pipe ditch etc. are constituted.Drainage procedure is as follows：The ponding of tunnel arch and side wall lining behind is blind by ring
Pipe, longitudinal blind pipe are discharged into tunnel lateral sulcus；Ponding exceedes the lateral sulcus cross-section of river, then introduces central drainage pipe by horizontal aqueduct
Ditch；Final tunnel internal water accumulation is drained into outside tunnel portal by lateral sulcus and central drainage pipe ditch.Traditional railway tunnel drainage system is set
Meter, the outer ponding of tunnel bottom structure can not be excluded.And a large amount of tunnel bottoms disease case shows, it is to cause that tunnel end liner, which builds outer a large amount of ponding,
The one of the main reasons of tunnel bottom disease.
During railway tunnel operation, under underground water and train load repeated action, if tunnel bottom structure can not with basement rock
Common stress is bonded well, then can cause the change of tunnel bottom structure stress, simultaneously because deformation generation is come to nothing, makes part
Underlying structure is hanging, and its drawing born, shear stress increase, and ultimately results in underlying structure cracking destruction, produces substrate and rises soil
Etc. phenomenon.Heavy haul railway Tunnel Base carries the ringing of big axle heavy train load, is easier base occur during tunnel operation
Bottom is risen soil, side gutter cracking and inverted arch variation etc. a series of diseases.These tunnel bottom diseases can threaten train traffic safety.
Utility model content
Technical problem to be solved in the utility model be to provide one kind can the outer drainage system of maintenance type railway tunnel bottom structure,
To exclude tunnel bottom ponding in time, effectively prevent the bottom substrate of the local rich water section of rich water tunnel or tunnel from producing disease of rising soil
Evil.
It is as follows that the utility model solves the technical scheme that its technical problem used：
One kind of the present utility model can the outer drainage system of maintenance type railway tunnel bottom structure, it is characterized in that：It includes being arranged at
Prefabricated permeable concrete pipe and horizontal blind pipe in the outer country rock of tunnel bottom structure, and it is arranged at the endoporus of prefabricated permeable concrete pipe
In longitudinal blind pipe；The length of the prefabricated permeable concrete pipe along tunnel Longitudinal extending, its top have it is longitudinally spaced and with
The vertical hole that endoporus is communicated；The horizontal blind pipe is set along tunnel is longitudinally spaced, and by vertical hole and prefabricated pervious concrete
Pipe is connected.
Vertical duct is provided with along tunnel is longitudinally spaced on longitudinal blind pipe, the position of each vertical duct is relative with inspection shaft
Should, its upper end is connected in inspection shaft, and lower end is connected with longitudinal blind pipe.
The beneficial effects of the utility model are that the outer ponding of tunnel bottom structure passes through in horizontal blind pipe ejectment to permeable concrete pipe
Or directly in seepage flow to permeable concrete pipe, subsequently into longitudinal blind pipe, be directly discharged outside Tunnel or again by ejectment to horizontal stroke
The drainage channels such as hole, drain cavern, exclude tunnel bottom ponding in time, effectively prevent the bottom base of the local rich water section of rich water tunnel or tunnel
Bottom produces disease of rising soil；When permeable concrete pipe internal water accumulation hydraulic pressure is higher, ponding can drain into inspection shaft by vertical duct
It is interior；Periodically apply water under high pressure in vertical duct, longitudinal blind pipe, permeable mixed mud pipe can be safeguarded, blocked to prevent drainage channel；
Longitudinal drainage foundation trench excavated volume is small, drainage system simple installation, quick, saves construction costs.
