Abstract
The utility model relates to a novel right -handed thread steel stock, including short stock, long anchor rod and dextrorotation intermediate junction head, short stock and long anchor rod link together through dextrorotation intermediate junction head detachable, the other end of this weak point stock passes through anchor agent to be fixed in the rock stratum, long anchor rod's the other end is located outside the rock stratum and installs anchor plate and nut, the length of short stock is 5 meters, and long anchor rod's length is 10 meters. The utility model has the advantages that: 1, the stock of retrieving all is finished products, 2, every recoverable two -thirds, 3 of stock, reduce support cost, 4, the hard rock tunnel rate of recovery is high.
Description
Technical field
This utility model relates to a kind of novel right-screwing threaded steel bolt.
Background technology
The anchor pole that at present mine support uses is right-screwing threaded steel bolt, owing to not having preferable recovery process, reclaims the anchor pole got off and all bend and cannot reuse more greatly in stope drift active workings.
Summary of the invention
For overcoming the defect of prior art, this utility model provides a kind of novel right-screwing threaded steel bolt, the technical solution of the utility model is: novel right-screwing threaded steel bolt, including Short bolt, long anchor pole and dextrorotation intermediate connector, together with described Short bolt and long anchor pole are removably attachable to by dextrorotation intermediate connector, the other end of this Short bolt is fixed in rock stratum by Anchor Agent, and the other end of long anchor pole is positioned at outside rock stratum and is provided with anchor dish and nut；A length of 5 meters of described Short bolt, a length of 10 meters of long anchor pole.
The utility model has the advantages that: 1, the anchor pole reclaimed is all finished product, 2, every anchor pole recyclable 2/3rds, 3, reduce support cost, 4, the hard-rock tunnel response rate high.
Accompanying drawing explanation
Fig. 1 is agent structure schematic diagram during this utility model use.
Detailed description of the invention
Further describe this utility model below in conjunction with specific embodiment, advantage of the present utility model and feature will be with describe and apparent.But these embodiments are only exemplary, scope of the present utility model is not constituted any restriction.It will be understood by those skilled in the art that and the details of technical solutions of the utility model and form can be modified or replace under without departing from spirit and scope of the present utility model, but these amendments and replacement each fall within protection domain of the present utility model.
See Fig. 1, this utility model relates to a kind of novel right-screwing threaded steel bolt, including Short bolt 2, long anchor pole 3 and dextrorotation intermediate connector 4, together with described Short bolt 2 and long anchor pole 3 are removably attachable to by dextrorotation intermediate connector 4, the other end of this Short bolt 2 is fixed in rock stratum 7 by Anchor Agent 1, and the other end of long anchor pole 3 is positioned at outside rock stratum 7 and is provided with anchor dish 5 and nut 6；A length of 5 meters of described Short bolt 2, a length of 10 meters of long anchor pole 3.
Long anchor pole (can reclaim the long anchor pole additional dextrorotation intermediate connector of 1 meter of length by under dextrorotation intermediate connector rotary unloading, the reason that remaining 0.5 meter of anchor pole has anchored due to accelerator, the outside of stope drift active workings and top board cannot reclaim, can be along with reclaiming during coal-winning machine back production near Ileal neobladder side).
