Description
Technical field
The utility model is related to mine and geotechnical anchor engineering technical field, more particularly, in a kind of hole only slurry component and
Using the grouting cable anchor or anchor pole of the component.
Background technology
Widely used hollow grouting cable anchor/anchor pole carries out supporting or Strengthening Tunnel and mine tunnel engineering both at home and abroad at present,
The fine or not key for hollow grouting cable anchor/anchor pole quality of constructing is the good drilling of closure, and otherwise slurries are leaked outside by drilling during slip casting, shadow
Ring the effect of grouting and reinforcing.Because of hollow grouting cable anchor/anchor pole in order to improve anchor force surface relief injustice caused to sealing of hole it is tired
Difficulty, the cable body of such as hollow grouting cable anchor is formed using helix rib steel wire twisting, is deposited between steel wire and between steel wire rib
In gap, sealing of hole is just very difficult.Drilling orifice rock is often relatively more broken under some complex geological conditions in addition, crack ratio
Relatively develop, excessively poor using traditional taper stop grouting plug sealing of hole effect, slurries flow out easily by the crack around aperture, especially
During using the diluter cement mortar of slurries or chemical pulp slip casting, spillage phenomenon is even more serious, does not realize anchor cable/anchor pole full length fastening
The purpose of country rock is reinforced with slurries, the waste of man power and material is caused.
In order to improve sealing quality patent of invention（The patent No.：ZL201210222718.6）Grouting cable anchor is only starched in hole, is carried
The technical scheme of sealing of hole in drilling is gone out, sealing of hole is to promote elastic tube by hard tube during hollow grouting cable anchor pretension, and elastic tube becomes
Shape blocks the gap between gap and lock ring metal tube and drilling between elastic tube and lock ring metal tube to realize sealing of hole,
It is only the closure to one end face of lock ring metal tube, due to elastic end surfaces and lock ring metal tube end face out-of-flatness, or firmly
The power of pipe extruding elastic tube is not big enough, causes elastic end surfaces to there is gap with lock ring metal tube end face, and slurries are flowed into from gap
Gap in elastic tube between cable body steel wire, then through being flowed out in cable body gap in rigid pipe, this hole-sealing technology difficulty is higher, can
It is poor by property, there is certain sealing of hole mortality, found in practice, spillage rate is 20-30%.A kind of rubber note of utility model patent
Starch anchor cable antiseepage set（Application number：201420788943.0）Propose gap between closure anchor cable steel wire and steel wire and stop grouting plug
Only slurry scheme, this scheme stops slurry, the preferable situation of wall rock condition suitable for aperture.
