Description
Technical field
This utility model is related to a kind of two-way stopper of pipeline.
Background technology
With the propulsion of Chinese Urbanization modernization construction process, urban Underground pipeline line development is very fast, city
The function such as city's underground utilities are responsible for the power transmission in city, information transmission, energy conveying, water drainage mitigation, waste dump, is city
The material base that city depends on for existence and development, is the important component part 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 " neural ", be known as " life line " in city, but the problem of thing followed underground pipeline management aspect
Also get more and more, the power failure that 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 as the obstinate disease of urban construction；The city's waterlog being caused due to pipe problems and road hydrops etc.
Phenomenon is customary, and the problem that underground utilities cause has become the pain being difficult in the minds of the common people of city eliminate.
While various urban infrastructures are improved, the management to underground utilities and the requirement of maintenance also more and more higher,
Pipe protection at the aspect such as electric power and communication typically adopted plastics, glass fibre, cement etc. in the past, and protective conduit is laid on pre-
In the ground lower groove first dug, and reserve manual work well 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 the waterproof sealing in pipeline must not process
When the animal such as hydrops in manual work well, mud and mouse is easy for entering in pipeline, and the cable in underground piping is made
Become and greatly endanger, or even cause power communication to interrupt.Simultaneously as underground piping be connected with manual work well identical, if with
The underground piping mouth of pipe waterproof sealing effect that manual work well is connected is not good, and the hydrops in manual work well can flow along physical features,
