Description
Technical field
This utility model is related to a kind of reverse discharge structure for reducing tunnel bottom water pressure, belongs to underground engineering guarded drainage
Technical field.
Background technology
With developing rapidly for the infrastructure constructions such as China's traffic, the energy, water conservancy, the construction scale of Tunnel Engineering is more next
It is bigger.Only by taking railway tunnel as an example, by the end of in by the end of December, 2015, the railway tunnel that the own Jing of China builds up and puts into effect is existing
More than 13000, total length has exceeded 13000 kilometers；3700 are exceeded railway tunnel is built, it is public that total length has exceeded 8700
In, exceed the summation of other All Countries.In addition, vcehicular tunnel is open to traffic, total length also breaches 10000 kilometers.When China it is big
Putting into effect for amount Tunnel Engineering, has many tunnel bottom structures to occur in that drum on base plate, rise soil, and railway roadbed cracking etc.
Disease.Line quality is had a strong impact on, is increased line maintenance workload, is caused the significant wastage of labour force and material, Er Qieyou
In substrate softening and the hardened integral, flexible for making railway roadbed of ballast aggregate reduce, affect train safe operation.In addition tunnel bottom is sick
Evil regulation difficulty is big, particularly lays the Railway Tunnel of non-fragment orbit, during by train travel density height, treatment construction skylight
Between short, non-fragment orbit is not easy-maintaining etc. that harsh conditions are limited, eradicate and administer extremely difficult.Substantial amounts of engineering practice shows, underground
Water is one of principal element that is bulging on tunnel occurs and rising soil.Thus, how to eliminate impact of the subsoil water to tunnel structure
It is the key point for solving above-mentioned disease.And the problem solved by subsoil water, tunnel domestic demand has good drainage system, it is necessary to logical
Cross new technology to solve.
This utility model is longitudinally confluxed by laterally catchmenting, and is realized by the reverse draining under nature head pressure, and is had
There is modularity, maintainable high, drainage path is wide, designs the advantages of facilitating, with extremely wide application prospect.
Utility model content
For achieving the above object, the technical solution adopted in the utility model is a kind of the reverse of reduction tunnel bottom water pressure
Discharge structure, the system include horizontal collecting system, longitudinal water guiding system, oblique system of turning one's coat；Laterally collecting system is arranged on
The bottom position of inverted arch construction joint, longitudinal water guiding system are arranged on inverted arch bottom along longitudinal direction laying, and the oblique system of turning one's coat is arranged on
The lower section of inspection shaft simultaneously oblique with longitudinal collector pipe connects；
Laterally collecting system is made up of horizontal drainable waterproofing plate 2, and horizontal drainable waterproofing plate 2 is laid on preliminary bracing 1 and is served as a contrast with inverted arch
Build between 3.
Longitudinal water guiding system is made up of longitudinal drainage plate and pipe 4, and pipe 4 is arranged on 1 bottom centerline position of preliminary bracing
Top is put, longitudinal drainage plate is laid on below pipe 4 and both sides.
Oblique system of turning one's coat is made up of one-way cock group 5, oblique drain pipe 6, inspection shaft 7, inverted arch center draining 8；Check
Well 7 is equally spaced along the centrage of inverted arch lining cutting 3；Inspection shaft 7 is connected with 6 top of oblique drain pipe, pipe 4, oblique draining
Pipe 6, inverted arch central drainage pipe 8 are sequentially arranged from the bottom to top；One-way cock group 5 is arranged on oblique drain pipe 6 and inverted arch central row
8 junction of water pipe, one-way cock group 5 are arranged on the bottom of inspection shaft 7, facilitate maintenance and inspection.
The one-way cock group 5 is made up of check valve, filter, and check valve is connected with filter.
Inverted arch filling 9 is layed in 3 top of tunnel inverted arch lining cutting.
Laterally collecting system is used for the waterproof of tunnel bottom structure and leads water in longitudinal water guiding system, and along longitudinal direction
Water guiding system is discharged；Oblique drainage system is for being discharged into tunnel bottom watery vomiting stream counter in inspection-pit and inverted arch Central drain.
The beneficial effects of the utility model are：
1st, using the drainage arrangement for reducing tunnel bottom water pressure of the present utility model, imitate using the draining of drainable waterproofing plate
Fruit is discharged to water in inverted arch Central drain, then together drains into outside tunnel.Avoid railway bed from rising soil phenomenon, protect railway
Roadbed.
2nd, later maintenance can be carried out to the tunnel using tunnel waterproof and water drainage system provided by the utility model, it is to avoid again
It is secondary to dig tunnel bottom structure so as to affect tunnel normally to run.
3rd, safeguarding for tunnel bottom drainage system can be realized, meets life requirement.
4th, Tunnel Second Lining behind water pressure can effectively be reduced.
