Description
Technical field
The present invention relates to the plugging device fields of water supply and sewerage pipeline, specially drainage pipeline pocket shape water blocking device and construction
Mounting structure and water blockoff tear blocking method open.
Background technique
Drainage pipeline water blockoff is generally there are two types of method at present, and one is being blocked with air bag, when dismounting, which deflates, is removed.Its disadvantage
Have: 1) safety is not high, rubber fatigue, due to air pressure is excessive and sharp objects are scratched etc., will lead to air bag and easily bursts wound
People；2) installation is inconvenient, when carrying out big-diameter pipeline closure, generally requires more people and coordinates, carries jointly, or need crane
Air bag could be put into the pipeline of underground；3) big using limitation, when having mud or solid refuse in pipeline, air bag can not pacify
Dress can the leak at pipeline dog-ear using air bag when pipeline section is the non-circular such as rectangular；4) cost is high, for 800 millimeters
The pipeline of caliber, the high quality air bag cost that water blockoff needs for the pipeline of more Large Diameter Pipeline, then need tens of thousands of up to ten thousand yuan or more
Even hundreds of thousands member；5) it blocks and uses duration, air bag also needs constantly to adjust after going into the well, it is made to be bonded pipeline；6) construct Shi Shoushui
Flow velocity degree and water level influence big.
Another kind is blocked with splicing steel plate.Its defect is: 1) water shutoff is not tight, and leak is serious；2) too heavy, installation is not square
Just；3) cost is high；4) it removes difficult；5) every set plugging device is only applicable to the pipeline of certain fixing model；6) duration is used；7) when constructing
It is influenced by water velocity and water level.
In the prior art, grant number is that the patent of " CN207599242U " discloses a kind of big-diameter pipeline plugging device,
It is in the nature a kind of air bag or water pocket to be inflated by secondary bag into main bag or water, still remains and burst risk or bag body is broken
Leak is split, bag body floating, can not play plugging action after hydraulic pressure reduces or flowed.
Summary of the invention
In order to overcome the above technical defects and insufficient, the present invention provides drainage pipeline pocket shape water blocking device and construction is pacified
Assembling structure and water blockoff tear blocking method open, can solve existing air bag water blocking device easily burst, steel plate block be easy leak and remove it is difficult,

The vertical shaft and its drainage pipeline sealing blocking of bottom.
The cross section outer profile perimeter of the pocket is maximum not less than in drainage pipeline to be blocked and described vertical shaft the two
Cross section inner wall perimeter；The height of the pocket is greater than the well head of the vertical shaft to the height of the drainage pipeline bottom.
The water blocking device includes multiple pockets, and successively housing is superimposed multiple pockets one by one, and each pocket exists
Open-mouth is fixed on the peg after being fixed the corresponding concatenation knotting of the cord hole of different pockets by wirerope.
The water blockoff of drainage pipeline pocket shape water blocking device construction mounting structure tears blocking method open, comprising the following steps:
1) it puts into pocket: the pocket being put into from vertical shaft, connects the pocket bottom sufficiently with horizontal drainage pipeline
Touching；
2) fixed: the cord hole of the pocket described in steel wire penetrating is simultaneously fixed on the peg of Shaft bank, makes the pocket
Opening trail；
3) material filling: filler is perfused into pocket from the opening of the pocket, makes the pocket bottom to surrounding expansion, diffusion
Until completely enclosing the drainage pipeline；
4) it operation and tears open stifled: the filler being extracted out using pump after the completion of operation, or is manually dug out, the mouth is further taken out
Bag.
The filler in step 3) is granular solid materials, and the pump in step 4) is vacuum pump.
The filler in step 3) is fluent material, and the pump in step 4) is liquid pump.
The fluent material specific gravity is greater than 1.
The filler in step 3) is sand, handstone, small ball or mud.
The present invention has following positive beneficial effect: 1) the invention belongs to a kind of gravity dams, securely and reliably, will not burst；2)
Cheap, raw material are easy to obtain；3) easy to use；4) blocking time is fast, and the used time is short；5) a kind of pocket is applicable to multiple
The pipeline of caliber is equally applicable to the pipeline of a variety of section configurations；6) it is not influenced by water velocity and water level；7) it removes simple；
8) cheap；9) it blocks tightly, it is almost watertight；Even if 10) there is partial fracture in bag body, by internal filler,
Plugging action can still be played.
