Abstract
The invention discloses an anchor cable for a cage-shaped mine and a preparation method thereof. The method comprises the following steps: clamping a steel stranded wire in the jig of a workbench, using a special cage weaving machine to rotate the steel stranded wire in the reverse direction of twist to scatter the steel stranded wire, then filling filler in the scattered steel stranded wire, using the cage weaving machine to rotate the steel stranded wire in the direction of twist to form a cage-shaped expansion joint on the steel stranded wire, and finally pressing and binding the two ends of the steel stranded wire to form the anchor cable for the cage-shaped mine. Under the action of the expansion joint of the invention, the resin anchoring agent can be fully and evenly stirred and combined with the bore wall firmly, the anchoring force is increased by 20% compared with that of the common anchor cable for the mine; by using the anchor cable for the cage-shaped mine, the anchor cable can be centered and straightened in a bore and not incline to the bore wall, thus increasing the anchoring force of the anchor cable; and the end of the cementing segment of the anchor cable for the cage-shaped mine is fixed by a snap ring, thus the end of the anchor cable can not be scattered.
Description
Technical field
The present invention relates to the anchor cable that mine support is used.
Background technology
Along with popularizing and development of domestic cable bolting technology, the range of application of Mine anchorage cable is also more and more wider, is applied to roadway, the surrounding rock consolidation in colliery or other mine.Mine anchorage cable is according to the steel strand one by one of anchorage depth intercepting, and anchorage cable anchoring in boring, is anchored at country rock on the hard top board; Simultaneously, invar twisted wire intensity rank is higher, and bigger prestressing force can be provided, and the compound roof of country rock bottom is connected as a single entity, and forms unified rigid panel, plays supporting effect preferably.But because steel strand are isodiametric, diameter is far smaller than the diameter of boring, with after the resin anchoring agent anchoring with the anchored force deficiency of drill hole wall.
Summary of the invention
Of the present invention day is for improving the anchored force of existing anchor cable, proposing a kind of anchor cable for cage-shaped mine and preparation method thereof.
For achieving the above object, the technical scheme that the present invention takes is: it comprises the anchor cable body, it is characterized in that, is processed with some cage type expansion joints on the anchor cable body, and the external diameter of cage type expansion joint is less than the diameter of anchoring boring.
The process for making of anchor cable for cage-shaped mine is: steel strand are clamped in the anchor clamps of workbench, with the volume cage device of existing special use the sth. made by twisting of steel strand to counter-rotating, steel strand are broken to scatter, then filler is filled in brokenly in the steel strand that loose, again with compile the cage device with the sth. made by twisting of steel wire to being rotated in the forward, make steel strand form the cage type expansion joint, at last shroud ring is withheld at the steel strand two ends, form anchor cable for cage-shaped mine.
Anchor cable for cage-shaped mine has more following advantage than common Mine anchorage cable: 1, because the effect of expansion joint can make resin anchoring agent stir, with the hole wall strong bonded, anchored force improves 20% than plain edition Mine anchorage cable; 2, it is stretching between two parties that anchor cable for cage-shaped mine can make anchor cable position in boring, not to the hole wall deflection, thus the anchored force of raising anchor cable.4, the solid section of anchor cable for cage-shaped mine end is fixed with snap ring, thereby can not scatter in the anchor cable end.
Description of drawings
Fig. 1 is the schematic diagram of embodiments of the invention;
Fig. 2 is the A-A profile of Fig. 1.
Marginal data: 1-anchor cable body; 2-cage type expansion joint; The 3-charges; The 4-shroud ring
The specific embodiment:
Further specify technical scheme of the present invention with reference to the accompanying drawings.
As shown in the figure, anchor cable for cage-shaped mine of the present invention is to be processed with a plurality of cage type expansion joints 2 on existing anchor cable body 1, and the external diameter of cage type expansion joint 2 is less than the diameter of anchoring boring.
During making: steel strand are clamped in the anchor clamps of workbench, with the volume cage device of special use the sth. made by twisting of steel strand to counter-rotating, steel strand are broken to scatter, then filler 3 is filled in brokenly in the steel strand that loose, again with compile the cage device with the sth. made by twisting of steel wire to being rotated in the forward, make steel strand form cage type expansion joint 2, at last shroud ring 4 is withheld at the steel strand two ends, form anchor cable for cage-shaped mine.
Claims (2)
1. anchor cable for cage-shaped mine, it comprises the anchor cable body, it is characterized in that, is processed with a plurality of cage type expansion joints on the anchor cable body, the external diameter of cage type expansion joint is less than the diameter of anchoring boring.
2. preparation method as exclusive rights 1 described anchor cable for cage-shaped mine, it is characterized in that, it is that steel strand are clamped in the anchor clamps of workbench, with the volume cage device of special use the sth. made by twisting of steel strand to counter-rotating, make that steel strand are broken to scatter, then filler is filled in broken in the diffusing steel strand, again with compile the cage device with the sth. made by twisting of steel wire to being rotated in the forward, make steel strand form the cage type expansion joint, at last shroud ring is withheld at the steel strand two ends, form anchor cable for cage-shaped mine.
