Abstract
The utility model discloses a bolt cable of novel specification in anchor /cable/mesh support roadway. The anchor cable of novel specification comprises an anchor cable (4), the anchor cable (4) is fixed in a drilled hole by a resin anchoring agent (1), and a part of the anchor cable (4) outside the drilled hole is fixed orderly by a tray (2) and a steel conical anchorage device (3); the anchor cable of novel specification is characterized in that the specification of the anchor cable (4) is Phi 21.6mm. The anchor cable of novel specification is higher in strength, is not easy to pull apart, can well realize the aim of enhancing the roadway support effect and preventing the accidents of roof separation and roof collapse of the roadway roof.
Description
Technical field
The utility model relates to novel specification anchor cable and is applied to coal mine down-hole tunnel support technology field.
Background technology
China's coal-mine underworkings roof timbering in recent years, more often adopt anchor/rope/net (namely, anchor pole, anchor cable, wire gauze) combined supporting, its stream line is specifications and models: Φ 15.24mm * 8300mm or Φ 15.24mm * 6300mm, 7 strands of low steel strand of speeding of high strength play the effect that strengthens supporting effect to back.This anchor cable can play the support action of short-term to pressure less tunnel in actual application, find but observe through long-term top board, anchor cable intensity is lower, is easily broken, and loses support action, cause the generation of tunnel absciss layer and fall of ground accident, have serious roadway support defective.
Summary of the invention
The technical problems to be solved in the utility model: a kind of New Anchor Cable is provided.Lower to solve intensity, easily broken, lose the technical problem that support action causes roadway roof absciss layer and roof fall accident.
The technical solution of the utility model is: novel specification anchor cable in a kind of anchor/rope/net supported laneway, comprise: anchor cable is fixed in boring by resin anchoring agent, and the outer part of anchor cable boring is fixed by pallet and steel cone anchorage successively, and the specification of anchor cable is Φ 21.6mm.
The beneficial effects of the utility model are: by the tunnel to identical anchor/rope under coal mine/net support form, carry out the long-term top board observation amount of shifting near verification experimental verification, the anchor cable intensity of this specification is higher, is difficult for being broken, can well reach the enhancing supporting effect of roadway, prevent the purpose that roadway roof absciss layer and roof fall accident occur.Driving face and emphasis lane are repaiied women's head-ornaments and be widely used under coal mine, and be economical and practical.Overcome the major defect of roadway support, greatly reduce coal mine roadway rate in bad repair and disrepair tunnel repair for 2nd time rate, improve safety and the stability that use in the tunnel, strengthen the safety assurance ability of Coal Mine Staff underground work.
The drill bit Φ 28mm of underground construction bolthole (anchor pole Φ 20mm) is the same with the drill bit of construction anchor cable (Φ 21.6mm), bores like this pricker and can jointly use, and when avoiding constructing anchor pole and anchor cable, changes back and forth drill bit, saves time.
Description of drawings
The roadway support generalized section of Fig. 1 New Anchor Cable of the present utility model and mounting structure enlarged drawing.
The specific embodiment:
By reference to the accompanying drawings, lower to the utility model anchor cable intensity, the optimal way of the technical scheme that technical problem takes such as easily being broken is described further:
Its concrete installation process is: anchor cable machine 5 joint Anchor Agents 1 → the insertions anchor cable 4 tops anchor cable machine top anchor cable machine → top tray 2 → steel cone anchorage prestressed stretch-draw after 3 → 40 minutes that puts in place stirring Anchor Agent 130 second → withdraw from that puts in place → start of holing → pack into.After installing, the anchor cable pretightning force is 150～300KN, carrying energy 454KN, Fracture Force 504 KN.
