The present invention relates to a kind of teleblem dash method for canal lining repair works under water, including following construction technology：The edge of sealing, back side will be needed in flexible water film to install sealant additional, upstream face installs counterweight additional；Flexible water film backwater is faced down submerged, patch is laid on the canal lining surface in Awaiting Overhaul region, and the unencapsulated edge exposure of flexible water film is more than the water surface of bank.The present invention has small investment, simple structure, selection environmental protection, stagnant water effect are good, and additional load is little, canal lining will not be injured, transport, installation, water transit depot are convenient, can prop up waterproof membrane with crane barge waterborne, mobile maintenance lock and maintenance gallery etc., on the operation basal plane for being provided, flexible working space is provided for lining cutting maintenance, it is also possible to as the dash curtain of speedily carrying out rescue work for preventing landslide area from expanding.
Description
Technical field
The present invention relates to a kind of dash method, and in particular to a kind of teleblem dash side for canal lining repair works under water
Method, belongs to hydraulic engineering technical field.
Background technology
Water diversion project is the trans-regional important infrastructure for distributing water resource rationally, and concrete lining open channel cost advantage shows
Write, using relatively broad in engineering, crack, degrade, waterproof failure, the canal lining disease such as landslide such as cannot be located in time
Reason, will seriously threaten engineering water delivery safety, for this purpose, carrying out the maintenance of water flowing phase heavy construction more.Economy, quickly offer operation base
Face, is the key technology for realizing water flowing phase lining cutting maintenance, the gear such as current general steel sheet-pile cofferdam, earth rock cofferdam, caisson cofferdam
Water scheme, not only high cost, long in time limit, and the canal section operation basal plane for traversing two sides can not be typically provided, while being also possible to brokenly
It is bad to account for nip lining cutting.
The content of the invention
To solve above-mentioned technical problem, it is an object of the invention to provide a kind of economy, efficiently dash method, in not
Under conditions of disconnected water delivery, the operation basal plane isolated with water in a canal is provided for canal lining maintenance, it can also be used to prevent landslide area from expanding
Dash curtain of speedily carrying out rescue work.
For achieving the above object, the technical solution used in the present invention is that a kind of teleblem for canal lining repair works under water keeps off
Water method, which includes following construction technology：The flexible water film is made up of the polyamide fibre dipped canvas for increasing density, upstream face point
Cloth is withheld；The edge of sealing, back side is needed to install sealant additional in flexible water film, upstream face installs counterweight additional；By flexible water
Film backwater faces down submerged, and patch is laid on the canal lining surface in Awaiting Overhaul region, and the unencapsulated edge of flexible water film goes out
It is exposed to more than the bank water surface.
The present invention the teleblem dash method for canal lining repair works under water be further：The sealant is by nontoxic poly-
Sulphur fluid sealant is made.
The present invention the teleblem dash method for canal lining repair works under water be further：The counterweight is by sand pocket system
Into.
The present invention the teleblem dash method for canal lining repair works under water be further：The flexible water film is not close
The edge of envelope can be in the water surface above exposure of side bank, also can be in the exposure simultaneously of both sides bank.
Compared with prior art, the beneficial effects of the utility model are：Dash formula investing is few, simple structure, selection
Environmental protection；Stagnant water effect is good；Transport, installation, water transit depot are convenient；Additional load is little, will not injure canal lining；It can be not only bank
Slope maintenance provides operation basal plane, can also provide operation basal plane for the maintenance of canal section tunneling boring, it is also possible to expand as landslide area is prevented
Big dash curtain of speedily carrying out rescue work；Crane barge waterborne, mobile maintenance lock and maintenance gallery etc. is can use to prop up waterproof membrane, in the operation for being provided
On basal plane, flexible working space is provided for lining cutting maintenance.
Description of the drawings
Fig. 1 is the teleblem dash method schematic diagram of the canal lining repair works under water for the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description the present invention is described in further detail：
As shown in figure 1, the present invention is a kind of teleblem dash method for canal lining repair works under water, which includes following applying
Work technique：The flexible water film 1 is made up of the polyamide fibre dipped canvas for increasing density, can be sunken to the bottom, upstream face point with deadweight
Cloth is withheld, and lifts by crane for the water surface；The edge of sealing, back side is needed to install sealant 2 additional in flexible water film 1, upstream face is installed additional
Counterweight 3；1 backwater of flexible water film is faced down submerged, patch is laid on 4 surface of canal lining in Awaiting Overhaul region, flexible anti-
1 unencapsulated edge exposure of moisture film is more than the water surface of bank.
The sealant 2 is made up of nontoxic polysulfide sealant, is closely connect with canal liner plate under the pressure effect of counterweight 3
Touch.
The counterweight 3 is made up of sand pocket.
1 unencapsulated edge of the flexible water film can be in the water surface above exposure of side bank, also can be same on both sides bank
When exposure, provide gateway for upkeep operation.
Dash formula investing of the present invention is few, simple structure, selection environmental protection；Stagnant water effect is good；Transport, installation, water transit depot
It is convenient；Additional load is little, will not injure canal lining；Not only operation basal plane can be provided for bank slope maintenance, can also be canal Duan Quan
Section maintenance provides operation basal plane, it is also possible to as the dash curtain of speedily carrying out rescue work for preventing landslide area from expanding；Available crane barge waterborne, movement
Maintenance lock and maintenance gallery etc. prop up waterproof membrane, on the operation basal plane for being provided, provide flexible operation for lining cutting maintenance empty
Between.
Specific embodiment above is only presently preferred embodiments of the present invention, not to limit the present invention, all at this
Any modification for being made within bright spirit and principle, equivalent substitute, improvement etc., should be included in protection scope of the present invention it
It is interior.
