Situations such as difference, it is severely deformed to often result in tunnel, roof fall, causes to seriously affect to tunnelling, Safety of Coal Mine Production.For enclosing
Rock is broken, soft rock develops the situation for causing supporting effect poor, scene often using grouted anchor bar or anchor cable to roadway surrounding rock into
Row supporting guarantees supporting effect of roadway.
Current grouted anchor bar primary structure is that anchor pole external surface uses overall length standard steep-pitch thread structure, and the body of rod is adopted
It is designed with hollow structure, carries out grouting design as Grouting Pipe using hollow lever during slip casting, which is applied to
After colliery tunnel support construction, have the following problems:
(1) hollow grouting anchor diameter is big, needs to be crept into using major diameter drill bit in boring procedure, with existing lane
Road supporting construction equipment mismatches, and needs independent matching operation drilling tool, and the bar tail of hollow grouting anchor uses Plastic cap pair
Body of rod end is blocked, and anchor bolt construction is caused to need to be drilled with the drilling of larger diameter.
(2) during coal mine roadway suspension roof support, carry out supporting timely and effective to roadway surrounding rock is needed, and provide higher
Prestressing force, after guaranteeing that supporting effect, hollow grouting anchor are set up, although foring full length fastening, nut is pre- next, can not be formed
Effective prestressing force causes supporting effect of roadway poor.
(3) with the increase of Coal Exploitation depth, crustal stress is increasing.The structure of full thread designs, and causes nut that cannot have
Effect pre-tightens, and causes supporting effect poor.
