The difficult above problem is removed or replaced to inner wall with more cable outer wall matching degree differences and cable.
To achieve the above object, the utility model uses the following technical solution:
A kind of pre-buried pipeline sealing structure of waterproofing work cable, it is pre- in concrete solid or masonry structure including being embedded in
Buried column part, the connecting tube being threadedly coupled with pre-buried column and threaded sleeve, the pre-buried column are provided with several through pre- buried column
The threaded connection hole of part, the connecting tube include integrally manufactured straight pipe and Taper Pipe section, the straight pipe outer wall be provided with
The straight pipe thread that threaded connection hole matches, the Taper Pipe section constitute coniform by wall thickness is gradually thinning, and Taper Pipe section is along its length
Several symmetrical V-notch are arranged in direction, and the straight pipe spiral shell of the Taper Pipe section and connecting tube is entangled in one end of the threaded sleeve
Line connection, the inner wall of the threaded sleeve other end shrink to form conical cavity to die, and conical cavity, which compresses Taper Pipe section, to be made to bore
Pipeline section is shunk.
Compared with the prior art, the utility model has the following beneficial effects:
1, it is threadedly engaged with the pre-buried column and connecting tube that are provided with several threaded connection holes, threaded sleeve entangles Taper Pipe section
It is threadedly engaged with connecting tube, rotation threaded sleeve drives conical cavity to compress the contraction of Taper Pipe section, shrinks Taper Pipe section and compresses simultaneously
Single cable in hermetically passing Taper Pipe section, the cable in each threaded connection hole individually seal, and keep single cable fastening close
Envelope is removed, is replaced independently of each other, is independent of each other, while simplifying increase and decrease, replacement cable process, improves cable installation effectiveness,
Alleviate labor intensity.
2, connecting tube and pre-buried column by being threadedly engaged, threaded sleeve entangles Taper Pipe section and connecting tube is threadedly engaged, revolve
Turn threaded sleeve conical cavity driven to compress Taper Pipe section to shrink to compress and seal cable, improve pre-buried column and cable it
Between leakproofness and reliability, eliminate the security risk of waterproof sealing system.
3, single cable sealing installation, increase and decrease, replacement etc. are easy to operate, time saving, laborsaving.

Specific embodiment
In order to make technological means of the utility model, creation characteristic, reach purpose and effect is more clear and is easy to
Understand, the utility model be further elaborated with reference to the accompanying drawings and detailed description:
As shown in 1~attached drawing of attached drawing 5, a kind of pre-buried pipeline sealing structure of waterproofing work cable, including it is embedded in concrete
Pre-buried column 1 in entity or masonry structure, the connecting tube 2 being threadedly coupled with pre-buried column 1 and threaded sleeve 3, it is described pre-buried
Column 1 is provided with several threaded connection holes 11 through pre-buried column 1, and the connecting tube 2 includes integrally manufactured straight pipe 21
With Taper Pipe section 22,21 outer wall of straight pipe is provided with the straight pipe thread 23 to match with threaded connection hole 11, the Taper Pipe section
