Abstract
The utility model provides a non - excavation trombone slide of power cable lays in the reaming that the construction of non - excavation formed, the trombone slide is contacted through the lateral wall by many cable protection pipes and forms with thermofussion welding fixed connection shaping, every cross -talk trombone slide by the sub - trombone slide of multistage, the cable protection pipe is circular haplopore pipe, in the time of in the trombone slide is worn to place the reaming in, many cable protection pipes forming sub - trombone slide use the reaming axis as symmetry axis symmetry setting, are equipped with the cement mortar layer with slip casting between trombone slide outer wall and reaming soil layer. The utility model discloses non - excavation technique construction to power cable is optimized, makes the trombone slide more be applicable to the construction operation that adopts non - excavation technique to lay power cable.
Description
Technical field
The present invention relates to electric power facility, especially power cable non-digging tube-pulling.
Background technology
Trenchless technology refers under the condition do not excavated or only excavate a small amount of operating pit, drilling and tunneling technology is utilized to carry out laying, repairing and change pipeline, it is efficient, high-quality, moderate cost, friendly to environment, have and do not affect traffic, the advantage such as free from environmental pollution, in many cases, than excavating load short construction period, integrated cost is low, fail safe good.Now become the Main Means of Municipal construction, for power construction, the power cable adopting this technology to lay need be placed through in trombone slide, how to optimize trombone slide for the trenchless technology of power construction, is a research direction.
Summary of the invention
The utility model proposes power cable non-digging tube-pulling, the trenchless technology construction for power cable is optimized, and makes trombone slide be more suitable for the construction operation adopting trenchless technology to lay power cable.
The utility model by the following technical solutions.
Power cable non-digging tube-pulling, be laid in the reaming of non-excavating construction, described trombone slide is fixedly connected with shaping by the sub-trombone slide of multistage with thermofussion welding, every cross-talk trombone slide to be contacted through sidewall by multi-cable protection tube and forms, and described cable protection pipe is circular single hole pipe; When trombone slide is placed through in reaming, the multi-cable protection tube forming sub-trombone slide for symmetry axis is symmetrical arranged, is provided with the cement sand bed with injection forming with reaming axis between trombone slide outer wall and reaming soil layer.
The diameter of described cable protection pipe and wall thickness, determined by the cable size in protection tube and trombone slide length.
Described trombone slide two ends are provided with active well.
When trombone slide is placed through reaming, trombone slide is unearthed angle between 8 degree to 15 degree, and trombone slide penetrating angle is also between 8 degree to 15 degree.
When trombone slide is placed through reaming, the radian of trombone slide any point is below 8 degree.
Form the multi-cable protection tube of sub-trombone slide, can movement mutually between the sidewall contacted.
In the utility model, trombone slide is fixedly connected with shaping by the sub-trombone slide of multistage with thermofussion welding, this design makes this product be easy to transport, can carry out with the sub-trombone slide that multistage is shorter when transporting, and during to site operation, can be whole piece trombone slide by the sub-trombone slide thermofussion welding of multistage again, and owing to have employed thermofussion welding technique, weld is without leakage gap, and after trombone slide is buried, underground moisture not easily invades.
In the utility model, every cross-talk trombone slide to be contacted through sidewall by multi-cable protection tube and forms, and described cable protection pipe is circular single hole pipe; When trombone slide is placed through in reaming, the multi-cable protection tube forming sub-trombone slide is symmetrical arranged for symmetry axis with reaming axis, forms the multi-cable protection tube of sub-trombone slide, can movement mutually between the sidewall contacted; This design makes the uniform force of sub-trombone slide in reaming; trombone slide is when constructing and at routine use; at the pressure that reaming hole wall place is subject to; be dispersed to multi-cable protection tube place to bear; improve overall stressed index, and due to the sidewall that cable protection pipe is contacting one another removable, make trombone slide when all side unbalance stress; energy nationality is exerted all one's strength by the Relative sliding between cable protection pipe and is tended to balance, and is conducive to promoting trombone slide load level.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail:
Accompanying drawing 1 is construction schematic diagram of the present utility model;
Accompanying drawing 2 is the cable protection pipe distribution schematic cross-sections in the utility model in different pipe number trombone slide;

Embodiment
As shown in Figure 1 and Figure 2, power cable non-digging tube-pulling 1, be laid in the reaming 3 of non-excavating construction, described trombone slide 1 is fixedly connected with shaping by the sub-trombone slide of multistage with thermofussion welding, every cross-talk trombone slide to be contacted through sidewall by multi-cable protection tube 4 and forms, and described cable protection pipe 4 is circular single hole pipe; When trombone slide 1 is placed through in reaming, the multi-cable protection tube 4 forming sub-trombone slide for symmetry axis is symmetrical arranged, is provided with the cement sand bed 5 with injection forming with reaming axis between trombone slide 1 outer wall and reaming 3 soil layer.
The diameter of described cable protection pipe 4 and wall thickness, determined by the cable size in protection tube 4 and trombone slide 1 length.
Described trombone slide 1 two ends are provided with active well 2.
When trombone slide 1 is placed through reaming 3, trombone slide 1 is unearthed angle between 8 degree to 15 degree, and trombone slide 1 penetrating angle is also between 8 degree to 15 degree.
When trombone slide 1 is placed through reaming 3, the radian of trombone slide 1 any point is below 8 degree.
Form the multi-cable protection tube 4 of sub-trombone slide, can movement mutually between the sidewall contacted.
