Abstract
The utility model patent is the body of rod, stop grouting plug, pallet, pad, spring, nut composition, it is characterized in that: the body of rod is made up of blunt anchor head, expansion sleeve, inner core tube and outer core pipe.Blunt anchor head and inner core tube are threaded connection, and inner core tube and outer core pipe are threaded connection.Expansion sleeve is enclosed within inner core tube and outer core pipe, and expansion sleeve two ends withstand on pallet and blunt anchor head respectively, and is provided with an elongated cover pipe seam, is provided with four cover pipe seams, in 90 ° of distributions at expansion sleeve near the end of blunt anchor head.It is fastening nut after anchor pole sends to design hole depth, the anchor pole expanded that expansion sleeve is formed after being squeezed distending by blunt anchor head.Then carry out slip casting by the inner core tube at body of rod center, strengthen anchoring.After use terminates, outer core pipe can oppositely screw out, recycling.Can be widely used in being out of shape in mine, tunnel, underground construction in larger heavily stressed breaking surrounding rock or soft rock.
Description
Technical field
The utility model relates to a kind of anchoring means, is particularly useful for being out of shape larger heavily stressed breaking surrounding rock or the grouting support of soft rock in mine, tunnel, underground construction.
Background technology
More and more important to the supporting of underground construction, anchor pole because of its supporting effect good, economic and practical, and by as commonly use support apparatus.In order to increase the contact force of anchor pole and country rock, improving supporting effect, having occurred various dilatancy anchor pole, but most dilatancy anchor pole, and when surrouding rock deformation, anchoring effect will lose efficacy, in Bracing Process, likely there is brittle fracture.Meanwhile, there is a very general problem in prior art anchor pole, after anchor pole use terminates, due to anchor rod anchored in country rock, cannot recycle, cause great waste.
Summary of the invention
The utility model patent provides a kind of slip casting expansion and part recoverable anchor rod, and this device can reach resistance to plucking anchoring requirement, and solves the problem of the not recyclable a large amount of waste of anchor pole.
The utility model is a kind of slip casting expansion and part recoverable anchor rod, is made up of blunt anchor head, expansion sleeve, inner core tube, outer core pipe, stop grouting plug, pallet, pad, spring, nut.It is characterized in that: be provided with blunt anchor head at the head of anchor pole, blunt anchor head is connected with inner core tube by screw thread, inner core tube is connected by screw thread with outer core pipe, expansion sleeve is provided with in the outside of inner core tube and outer core pipe, expansion sleeve head holds out against blunt anchor head, afterbody and pallet joint, pallet side is connected with expansion set pipe afterbody, and opposite side is connected with pad, spring and nut.
As improvement, expansion sleeve outer shape is cylinder, and sleeve pipe is provided with an elongated cover pipe seam, is provided with four short seams of sleeve pipe, the decile expansion sleeve mouth of pipe at expansion sleeve near the end of blunt anchor head.
The invention has the beneficial effects as follows: it is simple that this design has structure, easy for installation, during use, after Drilling anchor hole completes, blunt anchor head and inner core tube are connected, put expansion sleeve, then anchor bar body is sent to the hole depth of design, load onto backing plate, fastening nut then blunt anchor head is pulled back, squeezed bulging deformation when expansion sleeve is at one end withstood by pallet, the other end is extruded by blunt anchor head, with anchor hole inwall close proximity.By inner core tube slip casting inwards, slurries are derived by slurry outlet, carry out cementing solidifying to loose rock mass.Carry out the fastening stretch-draw of nut matched pallet and pad at hollow bolt afterbody, realize, to the disposable grouting support of rock mass, improve the supporting capacity of rock mass, increase the supporting intensity of roadway surrounding rock; When the rock mass generation large deformation of anchoring, tail springs can be made to produce and to stretch or extruding, avoid inner core tube generation fragility is cut off.After use terminates, outer core pipe can reversely rotate taking-up, recycles.Expansion tube expands can provide more powerful anti-pulling capacity for bolt support technology.The stability of country rock is increased by carrying out slip casting to inner core tube; When country rock produces distortion, tail springs produces certain stretching, and carries out allowing pressure, prevents anchor pole generation fragility from cutting off.After use terminates, outer core pipe can also reversely rotate taking-up, recycling, thus significantly reduces costs, and cuts the waste.
