Description
Technical field
The present invention relates to tunnel or road technology field, and in particular to a kind of waterproof side that the unimpeded based on existing tunnel combines
Method and device.
Background technique
Tunnel is the engineering works being embedded in stratum, is a kind of form of human use's underground space.Today's society,
In the city that traffic above-ground pressure increases increasingly, the development of underground space engineering technology so that the mankind Underground Rail Transit day
Attain perfect.Since the most buried depth of city underground engineering is shallower, and excavates location and is often accompanied by complicated surface state and geological conditions,
Especially in surface water body and rich water geologic structure, the water-impervious of tunnel roof is just particularly important.
Traditional tunnel water-impervious mainly wraps up one layer of waterproof material between first branch concrete layer and two linings, when encountering
The case where ground sweat is serious and water rich strata a large amount of water bursts, original waterproof material just shows slightly thin, this has resulted in tunnel
The difficult situation of water-impervious " impossible to guard against ".
It is general by the way of blocking when tunnel for having built completion seeps water, but seepage part is blocked
Afterwards, infiltration can be overstock in closure site, and can be seeped water near closure site or even seepage discharge is bigger, often fit to obtain it
Instead.
Summary of the invention
It is an object of the invention to: the tunnel for having built completion occurs seeping water and still can go out only with the mode of closure
The problem of now seeping water provides the waterproof method and structure of a kind of unimpeded combination based on existing tunnel.
To achieve the goals above, the technical solution adopted by the present invention are as follows:
A kind of waterproof construction that the unimpeded based on existing tunnel combines, including lining cutting and drainpipe, the drainpipe is by tunnel
The lining cutting is run through in lateral tunnel periphery.The application is that lining cutting is sensu lato tunnel-liner, including by the inside of tunnel to tunnel
The tunnel structure of the rock stratum contact surface in outside.
Preferably, the drainpipe is arranged in the arch bottom position in tunnel far from one end of rock stratum, within the drainpipe
Low outer high mode is obliquely installed, and 15 °~60 ° of the drainpipe angle with horizontal plane, so as to more convenient by tunnel
The stratum infiltration water water conservancy diversion of surrounding comes out.
Preferably, the waterproof construction further includes the control valve for controlling the drainpipe opening and closing, facilitate control.
Preferably, the drainpipe protrudes into rock stratum through one end of the lining cutting, this protrudes into one section of rock stratum to catchment
Section, it is provided with gully-hole in the section of catchmenting, so as to significantly more efficient guidance stratum filtration water.
Preferably, waterproof construction further includes control unit and the pressure sensing for monitoring drainpipe intracavity bottom hydraulic pressure
Device, the control unit are used to obtain the monitoring result of the pressure sensor and control the opening and closing of the control valve, work as pressure
Sensor monitors that when pressure is greater than the first preset value to exhaust the ponding in drainpipe, then control unit opens control valve
Turn off control valve.It is normally opened compared to drainpipe, this programme can be avoided drainpipe it is normally opened caused by obtain soil erosion, can
It economizes on resources.
Preferably, the waterproof construction further includes control unit and the water for monitoring the water that draining tube cavity gathers
Monitoring component is measured, the control unit is used to obtain the monitoring result of the water quantity monitoring component and controls opening for the control valve
It closes.Water quantity monitoring component can be the device of the depth of accumulated water in monitoring drainpipe, such as aqueous to monitor by monitoring height
Amount, when the structure monitored is greater than the second preset value, control unit opens control valve to exhaust the ponding in drainpipe, so
After turn off control valve.It is normally opened compared to drainpipe, this programme can be avoided drainpipe it is normally opened caused by obtain soil erosion, energy
Enough economize on resources.
The waterproof method that the unimpeded based on existing tunnel that disclosed herein as well is a kind of combines, blocks seepage part, by tunnel
Lateral tunnel periphery punching setting drainpipe is so that drainpipe runs through lining cutting in road.
Preferably, radial grouting is carried out to block seepage part to seepage part, so that reinforcing anti-seepage layer is formed, thus
It can effectively avoid continuing to leak.
Preferably, regular and/or quantitative and/or level pressure discharges the water gathered in drainpipe, compared to draining
Manage it is normally opened, this programme can be avoided drainpipe it is normally opened caused by obtain soil erosion, can economize on resources.
Preferably, the draining tube end on the inside of tunnel is arranged in the arch bottom position in tunnel, and axially every along tunnel
It is spaced 3-7m and arranges the drainpipe.
In conclusion by adopting the above-described technical solution, the beneficial effect of the application is: compared to only with closure
Mode, the application is directed through the building storey in tunnel using drainpipe while blocking so as to directly will be in stratum
Seepage flow is guided to drainpipe, arranges inside the drainage system into tunnel from drainpipe, due to being provided with the stratum hydraulic pressure of drainpipe
Lower than other stratum, so that the seepage flow in stratum can be guided to drainpipe, a certain range of seepage flow is just flow backwards near drainpipe
Come over, avoids seepage flow from penetrating into tunnel and cause treatment technology for tunnel seepage.
