Description
Technical field
The present invention relates to a kind of two-way plugging device of pipeline 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 power transmission, information transmission, the energy conveying in city, 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
Can 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 of 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.The problem of underground utilities trigger turns 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.
The pipe protection in terms of electric power and communication was typically using plastics, glass fibre, cement etc. in the past, and protective conduit is laid on pre-
In the ground lower groove first dug, and manual work well is reserved as paving line, inspection, maintenance, the setting rushed to repair, people according to standard
Work industry well is connected to form whole buried pipe diatom with pre-buried underground piping.Therefore must not handle in the waterproof sealing of pipeline
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 great 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 repairing of drawing water, the maintenance of physical features lower manual's operation well, 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 in the prior art, and such method wastes very much material
Material and artificial, especially work efficiency is too poor, often produces breach because expanding with heat and contract with cold, the vibrations of cable and periphery or even comes off,
If when repairing and maintenance need dismounting mouth of pipe closure, 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, be in the operation of present practice of construction one be difficult the problem of solution.
The content of the invention
The technical problem to be solved in the present invention, be to provide a kind of service life length, plugging effect persistently, integrated cost
It is low, can Reusability, eliminate because expanding with heat and contract with cold, the influence that the vibrations of cable and periphery are produced to plugging effect, installing/dismounting
Simply, the time that repairing is safeguarded is short and difficulty is low, will not also to destroy the pipeline of the insulating barrier of pipeline and cable two-way double stifled devices and
Its application method.

8. a kind of application method of the two-way plugging device of pipeline, it is characterised in that it is followed the steps below：
Step one：Cable（20）Pipeline is passed through when in use（21）, by upper rubber closeouts（2）With lower rubber closeouts（3）Edge
It is arranged on the cut-off rule in centre position（22）Two parts, line of cut are cut into respectively（22）In step-like；
Step 2：The upper rubber closeouts that step one is cut（2）With lower rubber closeouts（3）It is enclosed on cable（20）On, and under
Rubber closeouts（3）Close to pipeline（21）Port, squeezing action is forced into plate A（5）Plate B is forced with squeezing action（6）Pass through
Fixture block（13）It is stuck in rubber closeouts（2）The neck of upper end（14）It is interior, squeezing action is forced into plate C（7）With squeezing action power
Pressing plate D（8）Pass through fixture block（13）It is stuck in lower rubber closeouts（3）The neck of lower end（14）It is interior；
Step 3：After step 2, with four bolts（1）Sequentially pass through squeezing action and force plate A（5）Forced with squeezing action
Plate B（6）On upper bolt hole（16）, upper rubber closeouts（2）With lower rubber closeouts（3）On middle bolt hole（17）, extruding
Active force pressing plate C（7）Plate D is forced with squeezing action（8）On lower bolt hole（18）Interior nut（19）, by rubber closeouts and
Squeezing action forces plate and is fixedly connected into integral structure；
Step 4：The rubber closeouts and squeezing action that step 3 is assembled force the integral structure of plate along cable（20）
Slide into pipeline（21）It is interior, limited block（15）It is stuck in pipeline（21）Port, swivel bolt（1）So that squeezing action forces plate A
（5）Plate B is forced with squeezing action（6）Rubber closeouts in extruding（2）With lower rubber closeouts（3）, due to groove（11）Outer
In slope structure（12）So that interior sealing wall（9）Towards cable（20）Expand deformation, outer seal wall in carrying out（10）Towards pipeline
（21）Inwall carries out extending out deformation, continues swivel bolt（1）Until interior sealing wall（9）With cable（20）Connection forms plugging structure
And outer seal wall（10）With pipeline（21）Inwall connects to form plugging structure；
Step 5：After step 4, the process of repeat step one to step 4, in pipeline（21）Other port also install
Rubber closeouts and squeezing action force plate, in pipeline（21）Two ends form two-way plugging structure.
