Abstract
The utility model relates to the field of anchor cables for coal mines and specifically discloses a limiting device for anchorage length of a grouting anchor cable, which comprises the anchor cable and a stop-grouting plug, wherein a sleeve is sheathed outside the anchor cable, a rubber skin is sheathed at one end of the sleeve, a hole is arranged in the center of the rubber skin, one end of the anchor cable penetrates the sleeve and penetrates out from the hole of the rubber skin, the length of the anchor cable, which extends out of the rubber skin, is the anchorage length, and the part of the anchor cable, which extends out of the rubber skin is an anchorage section; the anchorage section and the sleeve are inserted into an anchor cable hole in surrounding rock bodies; the stop-grouting plug is used for being sheathed at one end of the sleeve, which is near to an inlet of the anchor cable hole after grout which is poured into the anchorage section in the anchor cable hole is solidified, and an arch-shaped tray is fixed at one end of the anchor cable, which is exposed outside the anchor cable hole through a lock. The limiting device can freely regulate the length of the grouting anchor cable at the anchorage end, enable the control of the anchorage length of the anchor cable to be more reasonable, enable the applied pre-tightening force to be acted on a larger range of the rock bodies, and fully play an active supporting role of the anchor cable.
Description
Technical field
The utility model relates to the colliery and uses the anchor cable field, particularly a kind of grouting anchorage cable anchoring length stopping means.
Background technology
The reasonable control of anchorage cable anchoring length can effectively improve the pretension length of anchor cable, better the prestressing force of anchor cable is delivered to rock mass inside widely.Using high-strength prestress grouting anchor cable,, usually ignored the reasonable length of the anchor cable end of anchor cable in the prior art for improving the anchored force of anchorage cable anchoring section to coal mine roadway, when side slope is stablized supporting.During grouting almost with whole anchor cable all as the anchor cable end, also can only act on very short free end even at this moment apply again big pretightning force, the prestressing force sphere of action of anchor cable is very little, and anchor cable almost is inserted in the country rock body as a reinforcing bar, can not give full play to its active support effect.
The utility model content

(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of grouting anchorage cable anchoring length stopping means, comprising:
Anchor cable, described anchor cable outside is arranged with sleeve pipe, one end of described sleeve pipe is arranged with the rubber skin, the center of described rubber skin is offered porose, one end of described anchor cable passes sleeve pipe and passes from the hole of described rubber skin, the length that described anchor cable stretches out the rubber skin is anchorage length, and the part that described anchor cable stretches out the rubber skin is an anchoring section; Described anchoring section and sleeve pipe are inserted in the anchor cable hole on the country rock body; Stop grouting plug is used for after the slurries that are filled into described anchor cable hole anchoring section solidify, and is set in the end of described sleeve pipe near anchor cable hole inlet; The arch pallet is fixed in the end that described anchor cable exposes the anchor cable hole by lockset.
Wherein, the material of described sleeve pipe is plastics or plastic-aluminum.
The size in the hole of described rubber skin and the diameter of anchor cable adapt.
Also comprise: the plastic-aluminum pipe, the one end is inserted in the anchor cable hole by described stop grouting plug.
(3) beneficial effect
Technique scheme has following beneficial effect: the grouting anchorage cable anchoring length stopping means that the utility model provides can free adjustment the length of anchored end of grouting anchor cable, more reasonable with the control of the anchorage length of anchor cable, the prestressing force that applies can be acted on the wider rock mass, give full play to the active support effect of anchor cable.
Description of drawings
Fig. 1 is the grouting anchorage cable anchoring length stopping means structural representation of the utility model embodiment.
Wherein, 1: anchor cable; 2: lockset; 3: the arch pallet; 4: stop grouting plug; 5: the plastic-aluminum pipe; 6: sleeve pipe; 7: the rubber skin; 8: the anchor cable hole.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, be the grouting anchorage cable anchoring length stopping means structural representation of the utility model embodiment, present embodiment comprises: anchor cable 1, and the outside of anchor cable 1 is arranged with sleeve pipe 6, the length of sleeve pipe 6 is shorter than the length of anchor cable 1, and sleeve pipe 6 is stretched out at the two ends of anchor cable 1 respectively; One end of sleeve pipe 6 is arranged with rubber skin 7, and the center of rubber skin 7 is offered porose, and anchor cable 1 passes sleeve pipe 6 and passes from the hole of rubber skin 7, and the length that anchor cable 1 stretches out rubber skin 7 is anchorage length, and the part of anchor cable 1 being stretched out rubber skin 7 is referred to as anchoring section; Anchor cable 1 stretches out the part of rubber skin 7, the part that is arranged with sleeve pipe 6 and sleeve pipe 6 and is inserted in the anchor cable hole 8 on the country rock body; Also comprise stop grouting plug 4, be used for after the slurries that are filled into anchoring section in the anchor cable hole 8 solidify that be set in the end of sleeve pipe 6 near anchor cable hole 8 inlets, arch pallet 3 is fixed in the end that anchor cable 1 exposes anchor cable hole 8 by lockset 2.Also comprise plastic-aluminum pipe 5, the one end is inserted in the anchor cable hole 8 by stop grouting plug 4, and the other end exposes anchor cable hole 8.Its middle sleeve 6 can be plastic-aluminum pipe, white plastic pipe etc.
The manufacturing process of grouting anchorage cable anchoring length stopping means of the present utility model is as follows:
1, make a call at the middle part of rubber skin 7 one with the identical hole of anchor cable 1 external diameter, rubber skin 7 be enclosed within an end of sleeve pipe 6 and tighten with iron wire;
2, the other end insertion sleeve pipe 6 of anchor cable 1 from sleeve pipe 6 worn out until the hole from rubber skin 7 middle parts, the length that anchor cable 1 passes the hole of rubber skin 7 is anchorage length;
3, regulate the anchorage length of anchor cable 1 by push-and-pull sleeve pipe 6, the anchor cable 1 of adjusting anchorage length is inserted in the anchor cable hole 8;
