Abstract
The utility model discloses a plastic cable pipe. According to the utility model, a cable is arranged in a cable pipe wall; the cable pipe wall is internally provided with a drain plug of which the material same with that of the cable pipe wall; the center of the drain plug is provided with a circular hole; and the circular hole and the cable are in interference fit. According to the technical scheme provided by the utility model, the drain plug is made of plastic and the cable pipe wall is also made of plastic, and the drain plug and the pipe wall are welded together after hot melting. Between the drain plug and the cable, the hole arranged at the center of the drain plug is slightly less than the outer diameter of the cable, because the outer wall of the cable has certain toughness, the outer wall of the cable is enclasped after blocking, and the sealing property is high.
Description
Technical field
The utility model relates to a kind of wireline operation field, relates in particular to a kind of method for blocking of cable tube, and relates to a kind of plastic cement cable tube obtained by this method.
Background technology
In recent years, along with the develop rapidly that power cable is built, it is underground that cable duct is clouded in the city just as a rule giant dragon, and the pipeline waterproof shutoff is applied in transformer station, Gong Jing, the underground station, sub-district by increasing.The waterproof plugging effect of worker's well, transformer station, underground station, sub-district, switch cubicle directly influences the fail safe of equipment, cable operation.
In original cable method for blocking, because shutoff material and cable tube wall material are inconsistent, the gap appears in meeting of long duration.Like 200920208533.3 patents, be bonded and sealed in the time of between resin after the expansion and the tube wall, long-time back the gap occurs and produces seepage because thermal coefficient of expansion is different.
The utility model content
The purpose of the utility model provides a kind of plastic cement cable tube of good seal performance.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Plastic cement cable tube in the utility model, cable are located in the cable tube wall, in the cable tube wall, are provided with and the identical plug of cable tube wall material, and circular hole is offered at the plug center, circular hole and cable interference fit.Described plug is a plastic material.
Adopt the utility model of technique scheme, process plug, weld together behind plug and the tube wall hot melt with the plastics that material is identical with tube wall.Between plug and cable, the boring ratio outside diameter of cable that the plug center is provided with is slightly little, because the cable outer wall has certain toughness, will hold tightly after the shutoff, and sealing is strong.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Embodiment
As shown in Figure 1; The method for blocking of the utility model plastic cement cable tube at first adopts the material identical with the cable tube wall to process plug, offers circular hole at the plug center then; The diameter of said circular hole is slightly less than the external diameter of cable, at last with welding together behind plug and the cable tube wall hot melt.
A kind of plastic cement cable tube that adopts said method to make, cable 2 is located in the cable tube wall 1, and the plug 3 identical with cable tube wall 1 material is set in cable tube wall 1, and circular hole is offered at plug 3 centers, circular hole and cable 2 interference fit.Because the cable outer wall has certain toughness, will hold cable tightly after the shutoff, sealing is strong.
Need to prove that above-mentioned plug is a plastic material.
Claims (2)
1. plastic cement cable tube; Cable (2) is located in the cable tube wall (1); It is characterized in that: the plug (3) identical with cable tube wall (1) material is set in cable tube wall (1), and circular hole is offered at plug (3) center, circular hole and cable (2) interference fit.
2. plastic cement cable tube according to claim 1 is characterized in that: described plug is a plastic material.
