This structure lets the pressure equipment put combined action through two kinds, improvement that can be better in the past anchor cable structure to coming from the not enough problem of pressing that lets that the gaff arouses.
Description
Art
This utility model relates to a kind of anchor cable structure, especially relates to for heavily stressed from stratum in support engineering, or being susceptible to large deformation engineering a kind of at roadway surrounding rock has the dual anchor cable structure allowing pressure effect.
Background technology
In Geotechnical Engineering, particularly in the more complicated underground engineering of geological conditions and slope project, requirement for surrounding rock supporting and the supporting of side slope is more and more higher, anchor cable has preferable mechanical characteristic because of it, have bearing capacity high and can apply bigger prestressing force, anchoring the degree of depth relatively big, make pressure effectiveness comparison obvious, the requirement of underground engineering and slope project can well be met.And high pre-stress that anchor cable has is poor at wall rock condition, can meet supporting condition from pressure significantly, and reaching have large-tonnage effect, country rock or supporting construction are formed a complete support system by anchor cable, improve the stability of structure.
But, along with anchor cable application in underground engineering and in slope project, and side slope heavily stressed especially from stratum crushes an urgent demand that situation is complicated, the anchor cable being had at present can not meet needs in terms of pressure allowing, have from scene allow the anchor cable of pressure effect exist below some problems:
(1) in the case of stratum is heavily stressed, anchor cable is owing to bearing suddenly from huge stress, when designing bearing capacity beyond it, and can not effectively carry out allowing pressure, make anchor cable be damaged, and the most whole anchor cable will lose its support action.
(2) surrouding rock deformation has a time effect, and the loss of prestress that prestress anchorage cable has, therefore in support engineering, along with the propelling of engineering, surrouding rock deformation can be gradually increased, and deformation can not effectively be alleviated.
(3) in construction, the afterbody of anchor cable is mainly fixed on country rock or on side slope sheet pile by pallet, generally, country rock surface irregularity, make anchor cable bend, the shift phenomenon of load occurs, the situations such as pallet generation tilting can be caused, the phenomenon that pallet is destroyed even occurs, causes failure of cable.
Have in some that presently, there are and allow the anchor cable of pressure effect, document have also been disclosed polytype, but mainly use anchorage installation this single method on anchor cable to solve anchor cable and allow pressure effect, if Chinese invention patent application is a kind of pressure-release anchor cable disclosed in 200820037459.9, it is simply that the above-mentioned described method of employing.Additionally to the problem that can not fix anchor cable very well at pallet, a kind of pressure-release anchor cable spherical rotation aligning device disclosed in Chinese patent application 201210405360.0, although improving the situation of the discontinuity that anchor cable exists to a certain extent, but it is not effectively improved pallet and there is the problem that bearing capacity is weak.
Summary of the invention
In order to effectively solve in ground support engineering, conventional anchor cable exists allows pressure scarce capacity, pressure mode is allowed to carry out allowing pressure only with one, not can solve surrouding rock deformation problem, and pallet bearing capacity is little, the phenomenon of discontinuity, devises and a kind of has the dual anchor cable structure allowing pressure effect.
This utility model is a kind of to have the dual anchor cable structure allowing pressure effect, by anchor cable body, anchorage, housing pallet, first allow pressure device, second allow pressure device and anchoring body form；Anchor cable body is made up of seven steel strand wires, and anchorage is divided into anchor clipper and anchorage body；First allows pressure device be made up of by pressure pipe and bottom deck top deck, double arc, and first device is positioned between housing pallet and anchorage；Second allows pressure device be made up of sleeve pipe and anchor cable body, and sleeve pipe is positioned at below housing pallet, arranges bearing ring between sleeve pipe and housing pallet.
As improvement, double arcs are seamless threaded steel pipe by pressure pipe, allow compressive strain reach 50～90mm.
As improvement, housing pallet is high-strength light steel construction, ovalize, and inner wall thickness is 10～30mm.
As improvement, by carrying out extruded by sleeve pipe and anchor cable body, and the hardness of sleeve pipe is less than anchor cable body, allows compressive strain can reach 100mm.
As improvement, after installation, first allows pressure device be placed in outside rock mass, and second allows pressure device be placed in rock mass.
The beneficial effects of the utility model:
1) this device allows pressure device by using two kinds, and first allows pressure device and second allow pressure device jointly act on, it is possible to is allowed to have the bigger pressure effect that allows, improves surrouding rock deformation；When anchor cable is operated, it not very big when pressing, when the deformation of needs is less, first passes through first and allow pressure device effect, Reducing distortion；When pressing bigger, first when allowing pressure device can not meet its demand, and second allows pressure device start to play a role, and by the dual pressure that allows, can improve country rock situation, meet the demand of large deformation.
2) by arranging housing pallet at the afterbody of anchor cable, after installation, housing pallet can well be buckled on scar, well improve the situation of discontinuity, stability due to its shell structure, bigger tension can be carried, prevent because the excessive pallet caused of tension damages the generation of phenomenon.
