Description
Technical Field
The invention belongs to the technical field of cable duct plugging, and particularly relates to a cable duct sealing plug.
Background
With the rapid development of economy in China, the infrastructure of each region is gradually improved, and higher standards and requirements are also needed for the construction and maintenance efficiency of underground pipelines. The prior protective tubes for underground power and communication are mostly made of plastics, glass fiber, cement and other materials, are pre-embedded in underground grooves dug in advance, and are provided with artificial wells according to standard distances to serve as construction operation points for wiring, inspection, emergency repair, maintenance and the like. The artificial well main body is constructed by a brick and cement adding structure, and each artificial well is communicated with each other through an embedded pipeline. If the pipeline waterproof sealing treatment is improper, the phenomenon of animal reproduction such as water seepage, ponding, silt and mice will appear in the pipeline for a long time, will all cause the influence to the safety and the construction maintenance of preparing the cable pipe, serious still can cause because of preparing the pipeline and not clearing up, the cable electric power that leads to laying afterwards or accident such as signal interruption. Meanwhile, as the pipelines are communicated, the accumulated water of the pipelines flows along the terrain, and a large amount of time is consumed for pumping water before maintenance, thereby greatly hindering the rush repair speed. If the sectional water pumping can be realized, the rush repair speed is undoubtedly improved, and therefore the pipeline needs to be plugged.
At present, the cable pipeline is mainly provided with three plugging devices, namely fireproof mud, cement and inflatable plugging.
In the cement plugging process, cement and yellow sand are required to be stirred on the spot, the using amount needs to be controlled, too few plugging effects are poor, too many plugging holes are easy to completely plug standby holes, and the later-stage use of the standby holes is not facilitated. And the cable pipe plugging device is not suitable for plugging a cable pipeline with an overlarge hole and cannot be used repeatedly.
The fire-proof mud plugging has high requirements on weather and temperature, the fire-proof mud cannot be fully softened when the temperature is too low, the plugging on the surface is complete, and various cracks are easy to appear after the fire-proof mud plugging is hardened for a period of time. The fireproof mud is easy to soften when the temperature is too high, cannot well play a plugging effect, and is not suitable for plugging outdoor lines. And the cable pipe plugging device is not suitable for plugging a cable pipeline with an overlarge hole and cannot be used repeatedly.
Compared with the two plugging conditions, the inflatable plugging is improved, but the use is inconvenient, and an inflation bottle needs to be carried to be placed above the cable well to inflate the inflatable plugging in the cable well. The operation process is too loaded down with trivial details and needs many people to cooperate, if the operating condition is too poor, even have the gas cylinder and drop the risk that the cable well caused the injures and deaths to personnel. And the cable duct hole undersize, the shutoff effect is not good, can not used repeatedly.
