In controlled range.
2.10 remove: after terminating to block, being removed, can save main material and recycle.
Either production lifts utility model: prospecting block-up position → cleaning substrate → production close measure structure → lifting
→ plastic film mulch cloth → pressure sandbag → draining concora crush → periodic observation displacement → dismounting.
3.1 prospecting block-up positions: prospecting needs the actual conditions of block-up position, and confirmation blocks width and is accurate to centimetre.
The cleaning of 3.2 substrates: will implement position mud before installation, sundries is cleaned out, and guarantee the smooth foreign of substrate.
3.3 production close measure structures: according to the data of the inspection of the scene of a crime, plugging structure is made near block-up position to film
Cloth substrate step (refers to above-mentioned construction and installation utility model).
3.4 liftings: the plugging structure made is lifted using truck crane to block-up position, this process should indirect labor
Compounding practice avoids destroying spout member during lifting.
3.5 plastic film mulch cloth: film cloth is allowed to bubble through the water column;When the longitudinal direction of a block film cloth is suitable for reading be completely fixed after, first by upstream
Film cloth be pressed onto river bed accurate location, film cloth is completed using streaming potential pressure moment, referred to as " plastic film mulch against the current ";One block film cloth
After completing, bag pressing is carried out in time, and previous process is repeated in the case where guaranteeing that the lap of splice requires and is laid with next block film cloth, film cloth
The lap of splice be usually not less than 3.0m.

3.7 draining concora crush: after film cloth installs, back side is drained, and draining will keep as far as possible the two sides water surface to synchronize
Even decline keeps pressure balance.During water surface decline, horizontal beam, film cloth bed course are reinforced from top to bottom.If there is exception,
Then stop arranging precipitation.
3.8 periodic observations displacement: stationary monitoring point is set at the top of plugging structure, and whether is the displacement of periodic monitoring plugging structure
In controlled range.
3.9 remove: after terminating to block, being removed, can save main material and recycle.
This utility model will not destroy existing component, and flexible waterstop sealing item needs can be used according to scene to be made
With, therefore there is no embodiment in structural schematic diagram, it is more thorough to the effect of protection, the closure of existing component after use.
In specific embodiment, such as west side water outlet implements this utility model in western suburb sandstone is cheated, due to the water outlet
Water quality is not achieved western suburb sandstone and cheats the water quality requirement that the interior south water to north supplies water, and needs to set up Temporary Cofferdam at drain port, wait go out
It is emitted into again after mouth of a river purification of water quality is up to standard in western suburb sandstone hole.Such situation cannot destroy existing outlet structure, cannot be dirty
Contaminate water quality, it is also necessary to dismounting rapidly, so carrying out in-depth improvement on the basis of pile film cofferdam.
The utility model is suitable for 5 meters of depth of water closure environment below, and the depth of water is more than 5 meters or two sides water-head is more than 5 meters
It is easy to cause the unstable phenomenon of structure.
The material that the utility model is selected can all recycle, and to water nonpollution.
The utility model is mainly applicable to existing structure water outlet temporary plugging, anti-seepage flow measure, with stake film
Cofferdam is different, and the utility model does not need to drive piles, and can avoid destroying substrate, dismounting is more quick, to water nonpollution.With it is existing
Pile film cofferdam bound form it is different, the utility model diagonal brace by whole trapezium structure be divided into several triangles, be added it is soft
Property sealing rod, more have stability and anti-permeability performance;It can be mounted directly, can also be made near block-up position in block-up position
It lifts.
There are two this close measure compression face is inclined surface, hydraulic pressure is strong: (1) lateral hydraulic pressure P1=water density * depth of water * g*
The self gravity P2=water density * depth of water * g*cosA of sinA (2) water;The wherein inclination angle on the inclined-plane A.(1) the sum of+(2) multiplied by by
Power area S is exactly the pressure that structure is subject to.
It can be seen that the depth of water and two-way depth of water height difference be influence structural stability will be because.The work generated by two sides depth of water difference
Firmly, it should control and be less than in close measure self weight range.Steel tube lapping select fastener overlap joint, horizontal direction lap-joint should be staggered to
Few 500mm.The critical load of steel pipe is 7.5KN/ ㎡, significantly larger than application range.The 3rd article of content in design A, can fill
Fission reveals design bright spot.
