Description
Technical field
The present invention relates to drainage system fields, more particularly to a kind of safe plugging structure and its installation and method for dismounting.
Background technique
Drainage system refers to various waste water, extra surface water and groundwater in collection and discharge human lives' sewage and production
The engineering of (lowering of watertable).Key facility has drainage channels or pipeline and its annex at different levels, depending on different drainings
Object and drainage requirement can also add water pump or other water lifting machineries, sewage treatment building etc..Be mainly used for farmland, mine,
Cities and towns (including factory) and construction site etc..
But in existing drainage system construction due to for example new and old pipe of many reasons plugs into, closed-water test etc. will be to pipeline
It is blocked, there are mainly two types of modes for closure: one is closure of laying bricks, another kind is rubber water-proof air bag, although brick envelope
Stifled is thick brick wall, can play the role of water in blocking pipe, and rubber water-proof air bag blocks water and is used in the built-in rubber of pipeline
Air bag, inflation allows rubber pneumatic bag and duct wall to have enough pressure to achieve the purpose that block water in rubber pneumatic bag, but makes
With or demolishing process in due to hydraulic pressure it is big, can wall be collapsed, while having sharp object that can also break rubber pneumatic bag in water, from
And cause to block and fail, the accidents such as cause casualties occur.
Summary of the invention
A kind of safe plugging structure is provided it is an object of the present invention to avoiding shortcoming in the prior art
Installation and method for dismounting, this method is easy to operate, effective to guarantee to block in installation, operation, the safety for removing three links
Can, effectively increase the generation that envelope water plugging effect reduces accident.
An object of the present invention is achieved through the following technical solutions:
A kind of installation of safe plugging structure and method for dismounting, comprising the following steps:
(1) raw material preparation: dimensional measurement is carried out to the pipeline blocked according to work on the spot environment, then calculating needs
The amount for the closure raw material wanted；
(2) it piles up the first sand packet: by inspection shaft by inside raw material artificial transmission to pipeline, while meeting water along water (flow) direction
Side, in a certain amount of sand packet of pipeline building up inside；
(3) plugging block is built: in the pipeline for completing step (2), along water (flow) direction in first back side Sha Bao, construction one
Block up plugging block compatible with internal diameter of the pipeline size；
(4) the second sand packet is piled up: in the pipeline for completing step (3), along water (flow) direction in the plugging block back side, that is, land side,
A certain amount of sand packet of pipeline building up inside completes entire closure work；
(5) it blocks and removes: in the pipeline for completing step (4), first by the protection of the second sand packet, manual demolition plugging block
Then top half removes the second sand packet in order again, next by the protection of the first sand packet, under manual demolition plugging block
Half part finally removes the first sand packet in order, and the entire work removed and blocked can be completed；
Set internal diameter of the pipeline wherein as H1, the piling height of the first sand packet and the second sand packet is H2, and the height of block wall is H3；
2 × H2 of the H1=H3, H1 >.
Further, in step (3), the plugging block with a thickness of 20cm to 30cm.
Further, in step (2) and step (4), the size dimension of the first sand packet and the second sand packet is 20
× 60cm to 45 × 90cm.
Further, in step (3), the plugging block is block wall of laying bricks.
The utility model has the advantages that the side heap that meets water along water (flow) direction is equipped with the first sand packet, and first due to during installation
The heap of sand packet height is not more than the half of internal diameter of the pipeline, can not only play temporary water dash, facilitate plugging construction, guarantees
Construction quality, while also reducing the water in pipeline and the construction safety blocked is guaranteed to the impact force of closure, while in the first sand packet
Back side construction one block up plugging block compatible with internal diameter of the pipeline size, guarantee plugging effect, be that the side that meets water exists along water (flow) direction
The other side of plugging block, that is, land side heap is equipped with the second sand packet, and the high height of heap of the second sand packet is not more than the two of internal diameter of the pipeline
/ mono-, it can not only prevent from blocking and collapse suddenly when removing, can also prevent having sharp object using rubber pneumatic bag Shi Shuizhong
Rubber pneumatic bag is broken, the safety for guaranteeing construction personnel is avoided.
When simultaneously in the process of dismounting, the envelope on sprue top need to be first sealed off under the protection of land side the second sand packet heap
It is stifled, it then tears land side the second sand packet heap open again, the closure of plugging block lower part is next removed under the protection for the side sand packet heap that meets water,
Finally the first sand packet heap of the side that meets water is removed, while being cooperated between the first sand packet heap, plugging block and the second sand packet heap three
It installs and dismounting sequentially and highly cooperates so that closure is obtained in the security performance of three installation, operation, dismounting links
The reinforcement of very high degree effectively increases envelope water plugging effect, reduces the generation of accident.
The second object of the present invention is to avoid shortcoming in the prior art and provide a kind of safe plugging structure, energy
Enough so that the plugging effect inside pipeline is best, sealing performance is high.
The second object of the present invention is achieved through the following technical solutions:
A kind of safe plugging structure, includes pipeline, is disposed with the first Sha Bao, envelope along water (flow) direction inside the pipeline
Sprue and the second sand packet, the plugging block is between the first sand packet and the second sand packet, the plugging block and the pipeline
Inner wall is fixedly connected.
Further, the pipeline upper end is provided with the inspection shaft being connected to the pipeline.
Further, the first sand packet and the second sand packet heap triangular in shape are set to the inner wall of the pipe.
