Abstract
Disclosed is a plugging method of a plastic cable conduit. The method comprises the steps: adopting materials which are the same with the materials of a cable conduit wall to be manufactured into a plug; then forming a round hole in the center of the plug, wherein the diameter of the round hole is slightly smaller than the external diameter of a cable; and finally, carrying out hot melting on the plug and the cable conduit wall and welding the plug and the cable conduit wall together. According to the plugging method of the plastic cable conduit, the technical scheme is adopted, so that the plug is made of plastics which are the same with the materials of the conduit wall, and the plug and the conduit wall are welded together after the hot melting. For the plug and the cable, the diameter of the hole in the center of the plug is slightly smaller than the external diameter of the cable, due to the fact that the outer wall of the cable has certain toughness, the plastic cable conduit can be clamped tightly after being plugged, and sealing performance is strong.
Description
Technical field
The present invention relates to a kind of wireline operation field, relate in particular to a kind of method for blocking of cable tube, and relate to a kind of plastic cable pipe obtained by this method.
Background technology
In recent years, along with the develop rapidly that power cable is built, cable duct is clouded in Urban Underground just as a rule giant dragon, and the pipeline waterproof shutoff more and more has been applied in transformer station, Gong Jing, underground station, residential quarter.The waterproof plugging effect of work well, transformer station, underground station, residential quarter, switch cubicle directly affects equipment, cable Operation safety.
In original cable method for blocking, due to the shutoff material and cable tube wall material inconsistent, the gap appears in meeting of long duration.As 200920208533.3 patents, be bonded and sealed in the time of between the resin after expansion and tube wall, long-time rear because thermal coefficient of expansion is different, the gap occurs and produce seepage.
Summary of the invention
The purpose of this invention is to provide a kind of method for blocking of plastic cable pipe of good seal performance, and plastic cable pipe obtained by this method is provided.
For achieving the above object, the present invention is by the following technical solutions:
In the present invention, at first the method for blocking of plastic cable pipe adopts the material identical with the cable tube wall to make plug, then offers circular hole at the plug center, and the diameter of described circular hole is slightly less than the external diameter of cable, will weld together after plug and cable tube wall hot melt at last.
Described plug is plastic material.
A kind of plastic cable pipe that adopts said method to make, cable are located in the cable tube wall, and the plug identical with cable tube wall material is set in the cable tube wall, and circular hole is offered, circular hole and cable interference fit in the plug center.Described plug is plastic material.
Adopt the present invention of technique scheme, make plug with the plastics that material is identical with tube wall, weld together after plug and tube wall hot melt.Between plug and cable, the boring ratio outside diameter of cable of plug center setting is slightly little, because the cable outer wall has certain toughness, will hold tightly after shutoff, and sealing is strong.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the method for blocking of plastic cable pipe of the present invention, at first adopt the material identical with the cable tube wall to make plug, then offer circular hole at the plug center, the diameter of described circular hole is slightly less than the external diameter of cable, to weld together after plug and cable tube wall hot melt at last, during welding, adopt common soldering appliance to get final product.
A kind of plastic cable pipe that adopts said method to make, cable 2 are located in cable tube wall 1, and at the interior setting of cable tube wall 1 plug 3 identical with cable tube wall 1 material, circular hole is offered, circular hole and cable 2 interference fit in plug 3 centers.Because the cable outer wall has certain toughness, will hold cable tightly after shutoff, sealing is strong.
Need to prove, above-mentioned plug is plastic material.
Claims (4)
1. the method for blocking of plastic cable pipe, it is characterized in that: at first adopt the material identical with the cable tube wall to make plug, then offer circular hole at the plug center, the diameter of described circular hole is slightly less than the external diameter of cable, will weld together after plug and cable tube wall hot melt at last.
2. the method for blocking of plastic cable pipe according to claim 1, it is characterized in that: described plug is plastic material.
3. plastic cable pipe that adopts the described method of claim 1 or 2 to make, cable (2) is located in 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), circular hole is offered at plug (3) center, circular hole and cable (2) interference fit.
4. plastic cable pipe according to claim 1, it is characterized in that: described plug is plastic material.
