According to the plugging device for the cable tube hole and the mounting method thereof, the structure of the device is simple, the operation is convenient, a tube hole wall and a cable can be effectively sealed through fire clay, and thus water proofing and fire proofing of the cable are guaranteed.
Description
Technical field
The present invention relates to a kind of plugging device and installation method thereof of cable pore, particularly relating to pipe orifice plugging device and the installation method thereof to wearing cable.
Background technology
Along with urban development, overhead wire take up an area many, unsightly, the low shortcoming of fail safe is also outstanding all the more, the use proportion of cable can be more and more higher.But because cable is embedded in missile silo for a long time, the situations such as the rising of level of ground water, the accumulation of rainwater, can cause cable shaft internal water accumulation to go up, make also to be full of in cable duct ponding, greatly reduce cable useful life and electric network security.
Therefore need to carry out shutoff to cable shaft pore, ensure that each cable shaft internal water accumulation is mutually not through, ensure the pipeline not ponding between well simultaneously.Comparatively ripe to cable shaft blank pipe blocking technology at present, but to wearing the pore shutoff of cable, do not have device that is effective, easy, low cost to carry out shutoff so far.
Summary of the invention
For solving the problem, the object of the present invention is to provide a kind of plugging device and installation method thereof of cable pore, its structure is simple, easy to operate, and pore wall and cable can effectively seal by fire-proof mud, thus ensures cable waterproof, fire prevention.
The present invention reaches above-mentioned object, and the present invention adopts following technical scheme:
A plugging device for cable pore, comprises hollow sealing plectane, and described hollow sealing plectane offers U-shaped socket, and described hollow sealing plectane engaging is provided with the curved insert corresponding with U-shaped socket; Described hollow sealing plectane comprises the first plectane layer, and described first plectane layer is connected with the second plectane layer by bolt, is placed with fire prevention mud layer between described first plectane layer and the second plectane layer.
The diameter of described first plectane layer is less than the diameter of the second plectane layer.
An installation method for the plugging device of cable pore, comprises the steps: that one of first the first plectane layer facing to cable tube hole; Then coordinate U-shaped socket cable fastening with curved insert, and hollow sealing plectane and plug-in unit are put into cable pore simultaneously; Then by locking fastening bolt, drive the first plectane layer and the second plectane layer mutually to draw close, and then the fire prevention mud layer of extruding central filler, after the expansion of fire prevention mud layer by with pore wall, cable is closely knit contacts thus the installation of plugging device.
Beneficial effect of the present invention is: the plugging device and the installation method thereof that the invention provides a kind of cable pore, and its structure is simple, easy to operate, and pore wall and cable can effectively seal by fire-proof mud, thus ensures cable waterproof, fire prevention.

Embodiment
Embodiment 1
As shown in Figure 1, 2, the present embodiment provides a kind of plugging device of cable pore, comprises hollow sealing plectane 1, curved insert 2, and wherein said hollow sealing plectane 1 offers U-shaped socket 14; Described plug-in unit 2 and U-shaped socket 14 can be with the use of.Described hollow sealing plectane 1 comprises the first plectane layer 11, and described first plectane layer 11 is connected with the second plectane layer 12 by 4 bolts 3.The diameter of described first plectane layer 11 is less than the diameter of the second plectane layer 12.Mud layer 13 of preventing fires is placed with between described first plectane layer 11 and the second plectane layer 12.
When the plugging device of the cable pore described in the present embodiment uses, first by the one side of the first plectane layer 11 in the face of cable pore.Diameter due to two plectanes is all less than the cable tube bore dia of required shutoff, and the diameter of the first plectane layer 11 is less than the diameter of the second plectane layer 12, and therefore form a vertebral body structure, assurance device puts into cable pore smoothly.Then coordinate U-shaped socket 14 cable fastening with curved insert 2, and hollow sealing plectane 1 and plug-in unit 2 are put into cable pore simultaneously.Then by fastening 4 bolts 3, drive the first plectane layer 11 and the second plectane layer 12 mutually to draw close, and then the fire prevention mud layer 13 of extruding central filler, after fire prevention mud layer 13 expands, will with pore wall, cable is closely knit contacts, thus guarantee cable waterproof, fire prevention.
The plugging device of a kind of cable pore described in the present embodiment and installation method thereof, its structure is simple, easy to operate, and pore wall and cable can effectively seal by fire-proof mud, thus ensures cable waterproof, fire prevention.
