Description
Technical field
The utility model relates to a kind of duct plug, is especially applicable to a kind of duct plug of cable pipeline.
Background technology
For problems such as the land used alleviating modern city are nervous, traffic pressure is large, meanwhile, also in order to promote the fail safe of appearance of the city construction and overhead high-tension line, increasing Cable choosing is laid in underground to replace aerial cable.Cable pipeline has the features such as stronger ageing-resistant performance drinks decay resistance, mechanical strength is high, bearing capacity is strong, weatherability, excellent insulating property, water absorption rate are low because of it, is the first-selection that user protects underground cable.
In underground cable line process of deployment, artificial well main body is that fragment of brick adds cement structures and builds up, and is communicated with between each artificial well by pre-buried pipeline.If cable pipeline waterproof sealing is dealt with improperly, time one is long, just there will be the situations such as infiltration, ponding, silt, foreign material and the animal reproduction such as mouse, termite in cable pipeline, all can impact the safety of cable itself and maintenance construction, serious also can cause the accident such as power breakdown or signal interruption.Meanwhile, because pipeline communicates, water accumulation of pipeline flows along physical features, needs the at substantial time to draw water, caused very big obstruction to repairing speed before maintenance.If segmentation can be realized draw water, can greatly improve repairing speed undoubtedly.In addition, for cable pipeline itself, the load performance of pipe ends will be inferior to continuous print pipe body part, and once the pipe shaft of pipeline is long, the bearing capacity of pipe shaft mid portion also can reduce relatively, this difficult problem safeguarded for not allowing the region of implementing multistage laying cable pipeline not only not deposit cable pipeline, to durability a kind of challenge especially of cable pipeline itself.In addition, also there are the problems referred to above for being layed in the leave unused cable pipeline of substitute of underground, pipeline internal water accumulation, deposition be husky, the situation such as foreign material and the animal reproduction such as mouse, termite, cable pipeline can be made when serious to lose use value.
Blocking scheme for cable pipeline plug generally has following two kinds: one to be artificial well total solution, and the suitable height of this way cost is not suitable for promoting; Two is carry out segmented seal leak stopping with cement, anti-cement etc. material to pipeline, the shortcoming of these ways is can because the cracking that expands with heat and contract with cold loses the effect of waterproof between material and cable pipeline, as long as cable does joining seam maintenance etc. operation and will destroy seal for pipe joints material require and reseal in addition, also inconvenient to cable dilatation in the future, need to recover just may destroy whole pipeline because pipeline has been fixed to block.
To sum up state, for the cable pipeline being layed in underground, no matter idle stand-by or using, reinforcement on the blocking and intensity of cable pipeline is all two matters of utmost importance awaiting solving, this directly has influence on a city and each intercity Communication Development, urgently proposes a conscientiously effective solution.
