Description
Technical field
The present invention relates to tunnel water handling technical field, and in particular to a kind of tunnel drainage system inspection window and its make
Use method.
Background technology
At present in tunnel structure of the Tunnel Engineering field using composite lining, generally supporting in the early stage and secondary lining
Between lay drainpipe, including ring direction drainpipe, longitudinal drainage pipe, transverse drain and central ditch etc., for secondary lining
Infiltration after block and splash guard is discharged, to eliminate hydraulic pressure.But during tunnel is runed, the silt taken out of due to seeping water becomes silted up
Product, it will usually cause the blocking of drainpipe, the document as disclosed in Chen Li《Drainpipe blockage problem is probed into railway tunnel construction》
(《Technology and market》, the 4th phase of volume 22, page 80, in April, 2015 in 2015), it is indicated that tunnel drainage system is vulnerable to mud
The influence of husky, calcareous crystal and form blocking, cause hydraulic pressure gather or Lining cracks infiltration etc. consequence.In karst
Magnesia, calcareous ion is generally rich in the tunnel that area is built, underground water, crystal is formed and gradually blocks tunneling drain.Due to
After tunneling is finished, drainpipe is generally enclosed in secondary lining behind, it is impossible to opens liner structure and checks and cleaning row
Water pipe, causes current effective dredging measure less.The countermeasure being usually taken is that inspection shaft and sand setting are set in central ditch
Pond, but this measure can only clear up the silting at central water ditch position.Also have by the way of water under high pressure and pressure-air to lining cutting both sides
Local draining pipe cleared up, but the draining scope tube that can be cleared up is also very limited.Above measure can not be effectively to tunnel
The blocking of road drainage system is cleared up, and recovers its drainability.
The problem of being easily blocked for tunneling drain, part expert proposes certain methods：The paper delivered such as Zhou Zhuo
《Groundwater In The Karst Area seepage flow Crystallization Plugging tunneling drain study mechanism and punishment suggestion》(Chang An University's master's degree opinion
Text, the 57-60 pages, in June, 2015), it is proposed that useization fills waterproof and changes filling-electricity seepage control technique, changes drainage grade, tunnel
Drainpipe is put into the bacterium of carbonic anhydrase, pressurization and removes tamper and tunnel, adds the measures such as scale remover；Zhang Xuefu, refined etc.
People has published some patents, such as (the publication number CN of patent 1 in removing tunneling drain Crystallization Plugging thing field
104196563A, publication date 2014.12.10), patent 2 (publication number CN 104196564A, publication date 2014.12.10), patent
3 (publication number CN104196565A, publication date 2014.12.10), observed by arranging overflow pipe drainpipe stopping state,
Change water velocity to prevent the generation of crystallization, arrange that spiral shell twisted axis etc. is constructed to remove Crystallization Plugging thing in drainpipe.More than
Measure, or there is the problem of construction is complicated, removing is not thorough enough, or only short run effect is effective, or need to enter the structure in tunnel
Row changes, or cost is higher, the problem of generally can not being fully solved current tunnel drainage blockage.In above measure,
Tunnel drainage system can not be carried out intuitively checking and directly clearing up, more drainage system can not be changed and safeguarded.
The content of the invention
The technical problem to be solved in the present invention is to provide the inspection window and its application method of a kind of tunnel drainage system, solve
Drainage system cleaning and the problem of Maintenance Difficulty during tunnel is runed, guarantee tunnel drainage system it is unimpeded.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of inspection window of tunnel drainage system, including casing, casing are arranged in the secondary lining of draining pipe surface；Case
Removable cover is connected with the top of body, bottom is surrounded by the edge of a wing；The edge of a wing is connected with splash guard, bottom half overlay area it is anti-
Covering on inspection socket, inspection socket is offered on water plate and is connected with inspection cover plate.
According to such scheme, the casing is rectangle, trapezoidal or ladder perpendicular to the cross sectional shape of drainpipe axis direction
Shape.
According to such scheme, the height of the casing and the consistency of thickness of secondary lining, removable cover and secondary lining
Flush.
According to such scheme, the removable cover is provided with what is matched with lock provided with lock, the top of the casing
Keyhole, is connected between removable cover and casing by lock and keyhole.
According to such scheme, insulation material is filled with the casing.
A kind of application method of the inspection window of tunnel drainage system, its step is as follows：
Step 1：Ring direction drainpipe and longitudinal drainage pipe are laid on the preliminary bracing surface in tunnel；
Step 2：In the reserved ring direction drainpipe of inspections window portion position scope and the both sides laying depth of longitudinal drainage pipe and
Plastic draining belt that drainpipe is highly flushed simultaneously is fixed with plastic draining belt nailing；
Step 3：Non-woven fabrics and splash guard are laid, and non-woven fabrics is fixed with non-woven fabrics nailing；
Step 4：The inspection socket of drainage system is cut off in waterproof plate surface, double sided self-adhesive tape is pasted on inspection socket periphery,
And cover inspection socket with inspection cover plate；
Step 5：The edge of a wing double sided self-adhesive tape of casing is connected with splash guard, the inspection mouth region of drainage system is covered
Domain, and ensure to be connected firmly；
Step 6：The keyhole that removable cover is buckled into casing top is closed；
Step 7：Secondary lining is applied, and ensures that removable cover is flushed with secondary lining surface；
Step 8：When needing to carry out repair and maintenance to ring direction drainpipe and longitudinal drainage pipe during tunnel operation, open and check
The removable cover of window；
Step 9：The inspection cover plate on splash guard is removed, ring direction drainpipe and longitudinal drainage pipe are cleared up and safeguarded；
Step 10：After the cleaning and maintenance work of ring direction drainpipe and longitudinal drainage pipe are finished, the inspection on splash guard is reinstalled
Cover plate is looked into, and buckles the removable cover for checking window.
Compared with prior art, the beneficial effects of the invention are as follows：Pattern is simple, install convenient, and tunnel can be with during runing
Examination and maintenance easily are carried out to tunnel drainage guard system, the unimpeded of tunnel drainage system are ensured, and do not influence tunnel existing
Structure type.
