Description
Technical field
The present invention relates to a kind of pipeline plug and its application method, more particularly to a kind of pipeline with strong sealing is double
To plugging device and its application method.
Background technology
With the propulsion of Chinese Urbanization modernization construction process, urban Underground pipeline line development is very fast, city
City's underground utilities are responsible for the power transmission in city, information transmission, energy conveying, water drainage mitigation, waste and the function such as dump, and are cities
The material base that city depends on for existence and development, is the important component of urban infrastructure, is to play city function, ensure society
Meeting economy and urban construction health, the important foundation of harmonious and sustainable development and guarantee, City Buried Pipeline is just as in human body
" blood vessel " and " nerve ", be known as " lifeline " in city, but the problem in terms of thing followed underground pipeline management
Also it is more and more, the power failure that is caused due to underground utilities reason, cut off the water, stop the supple of gas or steam and the accident such as communication disruption occurs again and again；" horse
Road slide fastener " phenomenon has become the chronic illness of urban construction；City's waterlog and road ponding for triggering due to pipe problems etc.
Phenomenon is customary, and the problem that underground utilities trigger has turned into the pain for being difficult to eliminate in the minds of the common people of city.
While various urban infrastructures are improved, requirement to management and the maintenance of underground utilities also more and more higher,
Pipe protection at the aspect such as electric power and communication in the past typically uses plastics, glass fibre, cement etc., and protective conduit is laid on pre-
In the ground lower groove first dug, and according to the reserved manual work well of standard as the setting for spreading line, inspection, maintenance, repairing, people
Work industry well is connected to form whole buried pipe diatom with pre-buried underground piping.Therefore the waterproof sealing in pipeline must not process
When the animal such as ponding, mud and mouse in manual work well is easy for entering in pipeline, and the cable in underground piping is made
Into greatly harm, or even power communication is triggered to interrupt.Simultaneously as underground piping is connected identical with manual work well, if with
The connected underground piping mouth of pipe waterproof sealing effect of manual work well is not good, and the ponding in manual work well can flow along physical features,
Great trouble can be caused to the repairing of drawing water of physical features lower manual's operation well, maintenance, even low land can be caused when rainwater is excessive
Waterlogging disaster at gesture.Therefore the waterproof closure of underground piping spool mouthful is particularly important.
Custom uses the conventional approach of the tube sealings such as fire-proof mud, cement, yellow sand mouthful, such method to waste very much material in the prior art
Material and artificial, especially work efficiency is too poor, often because expanding with heat and contract with cold, the vibrations of cable and periphery produces breach or even comes off,
If when repairing and maintenance need the dismounting mouth of pipe to block, the material such as fire-proof mud, cement, yellow sand has been hardened, it is extremely difficult to remove and clear
Reason, is also easily destroyed the insulating barrier of pipeline and cable, is a very scabrous problem in present practice of construction operation, at present
Have pipeline is blocked using flexible seals, principle is in putting flexible seals into cable tube, then to tighten connector
Bolt, force flexible seals to deform, the inner ring side face of flexible seals is adjacent in the outer of cable surface and flexible seals
Periphery is adjacent in cable inside pipe wall, so as to form sealing inside and outside cable tube, needs to enter flexible seals during this
Row cuts out an opening, is easy to it to enter in cable tube, and a problem occurs in that case, exactly when tightening connection
When the bolt of part causes that flexible seals deform, crack occurs at opening, cause sealing not strong, and connector is close with flexibility
Connection between sealing also occurs the not strong problem of sealing.
Existing flexible seals plugging structure, is first to cut flexible seals, is enclosed within cable, then will extruding
Active force pressing plate is pressed in the upper and lower ends of flexible seals, and forces plate company through flexible seals and squeezing action by bolt
Slided into pipeline along cable after being connected into one, install and use and bother very much.
The content of the invention
The technical problem to be solved in the present invention is that offer is a kind of installs and uses the simple and pipeline with strong sealing pair
To plugging device and its application method.
The present invention is realized by following proposal：A kind of two-way plugging device of pipeline with strong sealing, it includes that rubber is sealed
Blocking piece and squeezing action force plate, and the rubber closeouts and the squeezing action force plate and be bolted, and rotation is described
Bolt enables to rubber closeouts to deform, and the rubber closeouts are provided with two, interior rubber closeouts and outer rubber closeouts,
The interior rubber closeouts are located at the inner side of the outer rubber closeouts, in the interior rubber closeouts and outer rubber closeouts
An opening is provided with, the opening of the interior rubber closeouts is in step-like, and the opening of the outer rubber closeouts is by interior contiguous block
Overlapped with outer contiguous block and formed, the thickness of the interior contiguous block and the outer contiguous block is the one of the outer rubber closeouts thickness
Half, the squeezing action forces that plate forces plate including upper squeezing action and lower squeezing action forces plate, the upper squeezing action power
Pressing plate and the lower squeezing action force plate by two and half pressing plate interconnections into circular ring structure, and the upper squeezing action is forced
The upper end that the lower end of plate and the lower squeezing action force plate is equipped with two draw-in grooves, inner card cage and exterior bayonet slot.
The two ends of the interior rubber closeouts are connected in the inner card cage, the two ends point of the outer rubber closeouts
Be not connected in the exterior bayonet slot, the squeezing action force plate be wrapped in the outer rubber closeouts outside and it is described in
The inner side of rubber closeouts, the spiral shell passed through for the bolt is equipped with the interior rubber closeouts, the outer rubber closeouts
Keyhole, the bolt is passed through between the interior rubber closeouts and the outer rubber closeouts, and the upper squeezing action is forced

10. a kind of a kind of application method of the two-way plugging device of pipeline with strong sealing based on claim 1-9, its feature
It is that it is followed the steps below：
Step one：Cable passes through pipeline when in use, rubber envelope in the rubber closeouts that will be bolted when dispatching from the factory
Blocking piece（1）With outer rubber closeouts（2）Broken into two with one's hands along opening and be enclosed within cable, and closed, upper squeezing action is forced into plate（5）With
Lower squeezing action forces plate（6）By open bolt hole（9）Place breaks into two with one's hands and is enclosed within cable, also closes；
Step 2：Slided into pipeline along cable after step one, edge（11）The port of pipeline is stuck in, swivel bolt is caused
Upper squeezing action forces plate（5）Rubber closeouts in extruding（1）With outer rubber closeouts（2）So that interior rubber closeouts（1）'s
Centre position carries out interior expansion and deforms towards cable, outer rubber closeouts（2）Centre position carry out extending out change towards inner-walls of duct
Shape, continues swivel bolt until interior rubber closeouts（1）It is connected to form plugging structure and outer rubber closeouts with cable（2）With
Inner-walls of duct connects to form plugging structure；
Step 3：After step 2, the process of repeat step one to step 2 also installs rubber in the other port of pipeline
Closeouts and squeezing action force plate, and two-way plugging structure is formed at the two ends of pipeline.
