Abstract
The utility model discloses an anchor rod using a No. 10 seamless steel tube as the rod body. The rod body is provided with the explosive cores composed of the detonating fuses, the No. 3 ammonium nitrate explosive and the electric detonators along the full-length. The bacterium rods filled with the explosive cores are inserted into the rock holes, are detonated concurrently and make the steel tubes generate the diametral plastic deformation, in order to squeeze the rock wall and achieve the anchoring goal. The utility model has the advantages of simple structure, convenient installation, big primary anchoring force, immediately anchoring, etc. So the utility model is suitable for the tunnel of the soft rock mass immediately requiring to be provided with the support restriction.
Description
Explosion anchoring pipe anchor rod belongs to roadway anchoring support device class.
At present, bolt-spary supports has become support form comparatively desirable in the shaft and drift supporting.The different anchor pole of various functions is by a large amount of employings.Full length fastening is arranged and put anchoring rod with regard to anchoring position branch; With regard to the material branch steel (steel pipe, reinforcing bar, wire rope) and wooden anchor pole are arranged; With regard to the anchor type branch wedge-type, bloated shell-type, static(al) expand tube formula and glued formula anchor pole are arranged down; And glued formula is divided the cement mortar gluing, plastic bonding, rapid setting cement gluing.These multi-form anchor poles are owing to have different anchored force and the tunnel that the different reinforcement mechanisms of rock mass is used for reinforcing different lithology respectively.Generally believe that for the weak stratum tunnel full length fastening is an optimised form.And the anchoring of total length mortar is difficult to control owing to slip casting is full, and bond stress is poor between country rock and the mortar, and especially just anchored force is less, does not reach instructions for use.At present, although the pipe-seam type anchor rod of promoting the use of at soft-rock tunnel overcomes to some extent to above-mentioned shortcoming, just anchored force improves little.If in soft-rock tunnel, use,, cause anchored force to reduce because soft rock can be clamp-oned tube chamber from pipe seam.In view of the foregoing, a kind of waterpower expand tube formula anchor pole is succeeded in developing, but this anchor pole complex process, is difficult for construction.Explosion anchoring pipe anchor rod is at the shortcoming of above-mentioned these anchor poles and design.
The purpose of this utility model is, design a kind of simple in structure, convenient by dress, can with the anchoring of detonating simultaneously of face driving, anchored force can increase 2-3 doubly, and production efficiency is improved a lot.
The technical solution of the utility model is that No. 10 seamless steel pipes of employing low-elasticity-modulus, big elongation rate are done the anchor pole main body, will the plastic pipe of No. 3 ammonpulvers be housed, be wound into the outside of detonating fuse, detonating fuse one end is equipped with detonator, and steel pipe one end is welded with ring washer, is subjected to the outer anchor dish that is with.
See Fig. 1, explosion anchoring pipe anchor rod of the present utility model is made of back-up ring 1, anchor dish 2, steel pipe 3, detonating fuse 4, gunpowder 5, detonator 6, stemming 7.
During use, with explosion anchoring pipe anchor rod insert to bore in the good petrosal foramen, energising makes blasting cap initiation, detonating fuse, gunpowder detonate successively, make the steel pipe expansion, are fixed in the petrosal foramen.
Claims (3)
1, a kind of explosion anchoring pipe anchor rod is made of steel pipe, it is characterized in that: steel pipe adopts No. 10 seamless steel pipes, and the priming core is housed in the pipe.
2, according to the said explosion pipe anchor rod of claim 1, it is characterized in that managing in priming core core be by, the plastic pipe that No. three ammonpulvers are housed is wrapped on the detonating fuse, detonating fuse one end is by putting detonator.
3, by the said explosion anchoring of claim 1 pipe anchor rod, it is characterized in that steel tube end part is welded with back-up ring.
