Abstract
The utility model relates to a yielding anchor cable device, which is particularly applicable to support for mines, tunnels and underground engineering. The yielding anchor cable device is characterized in that a steel stranded wire and a steel stranded wire friction damper are disposed inside an anchor tube, the steel stranded wire friction damper is embedded onto the end of the steel stranded wire, and the anchor tube is provided with threads. The yielding anchor cable device has the advantage that the steel stranded wire and the steel stranded wire friction damper are disposed inside the anchor tube, the steel stranded wire friction damper moves in the anchor tube to function in yielding when rocks greatly deform due to abnormal weighting while an anchor cable is used in geotechnical anchorage, accordingly damage to the anchor cable is avoided, and safety use performance is increased.
Description
(1) technical field: the utility model relates to a kind of allowing and presses the anchor cable device, is particularly useful for supportings such as mine, tunnel or coal mine roadway.
(2) background technology: the anchor cable that geotechnical engineering is used for anchoring be by metallic steel twisted wire, resin anchoring agent or cement anchoring agent, ground tackle, pallet is supporting forms.When the geotechnical engineering anchoring construction, anchor cable section of anchoring into and rock stratum are through the bonding formation one of anchoring agent, and the ground tackle of process anchor cable body afterbody makes pallet exert pressure to rock layer surface and forms anchoring again.Because anchor cable section of anchoring into and rock stratum are through the bonding formation one of anchoring agent, the ground tackle of process anchor cable body afterbody makes pallet exert pressure to rock layer surface and forms anchoring again, excessive anchor cable bearing load transfinites if compressive strain is come in the rock stratum, certainly will cause the anchor cable damage anchoring accident to occur.
(3) summary of the invention: the purpose of this utility model mainly adopts a kind of allowing press the design of anchor cable device, and the rock stratum is come the problem that compressive strain damages anchor cable unusually when solving anchoring, improves the safety in utilization of anchor cable.
A kind of allowing described in the utility model presses anchor cable Design of device scheme to be: it is made of steel strand, steel strand friction device and anchoring pipe and stirring-head.Be characterized in: steel strand and steel strand friction device are built in the anchoring pipe, and its steel strand friction device is that taper edge is enclosed within the steel strand end, and the anchoring pipe is that entire body has spiral lamination or an end has the spiral lamination other end not with the tubular articles of spiral lamination.
Originally make real novel described a kind of allowing press the anchor cable device compared with prior art, its useful contribution is: because steel strand and steel strand friction device are built in the anchoring pipe, the steel strand friction device moves the pressure effect that allows of playing when making anchor cable rock stratum in ground anchorage press the rock stratum, back large deformation to occur unusually in the anchoring pipe, make anchor cable injury-free, improve safe application performance.
(4) description of drawings: Fig. 1 is the utility model schematic diagram.
(5) specific embodiment: 1 pair of a kind of allowing of the present utility model presses the anchor cable device to be further described as follows in conjunction with the accompanying drawings: a kind of pressure anchor cable device that allows described in the utility model is to be made of steel strand 1, steel strand friction device 2 and anchoring pipe 3 and stirring-head 4, steel strand friction device 2 edges are enclosed within on steel strand 1 end and are built in the anchoring pipe 3, and stirring-head 4 devices are in anchoring pipe 3 ends.
Claims (3)
1. one kind allows and presses the anchor cable device, be to constitute by steel strand (1), steel strand friction device (2) and anchoring pipe (3) and stirring-head (4), be characterized in: steel strand (1) and steel strand friction device (2) are built in the anchoring pipe (3), its steel strand friction device (2) is that edge is enclosed within steel strand (1) end, and anchoring pipe (3) has spiral lamination.
2. a kind of allowing according to claim 1 pressed the anchor cable device, it is characterized in that anchoring pipe (3) is that entire body has spiral lamination or an end has the spiral lamination other end not with the tubular articles of spiral lamination.
3. a kind of allowing according to claim 1 pressed the anchor cable device, it is characterized in that steel strand friction device (2) is that edge is enclosed within steel strand (1) end, and its shape is taper.
