Abstract
The utility model provides an easily-recycled quick-setting cement anchor rod suitable for underground engineering support, which comprises an anchor rod body, a tray, nuts, a baffle and a plastic sleeve, wherein the anchor rod body is a long rod with thread sections at two ends; the baffle plate is welded with the nut, and a plastic sleeve is arranged in the rapid-hardening cement cartridge; the anchoring section of the anchor head is connected with the joint part of the rod body by adopting a plastic sleeve loop, a baffle plate and a nut, the tail part of the rod body is a square head, so that the anchor rod is convenient to assemble and disassemble, most parts of the anchor rod can be easily recycled for repeated use after the service period is reached, the material is saved, the cost is reduced, the recovery rate reaches about 90 percent of the total cost, and the economic benefit is remarkable.
Description
The utility model relates to a kind of underground engineering support device, especially a kind of callable rock anchorage anchor pole.
The wedge-type that mainly contains the present easy recovery anchor pole that uses down easily reclaims anchor pole ［ patent No. is: 91213510.7 easily reclaim anchor poles ］, the resin anchoring type easily reclaims anchor pole ［ patent No. is: 91213511.5 easy recovery anchor poles ］ etc.; Inverted wedge type anchor rod is big because of its installation difficulty, and poor reliability is so there be limited evidence currently of uses this type of anchor pole.And for example resin anchor is compared with the rapid setting cement anchor pole, the former anchoring agent cost height, and its snakelike anchor head reclaims not come out, and the rate of recovery is low.
The purpose of this utility model is to provide a kind of novel easy recovery anchor pole in order to overcome above-mentioned the deficiencies in the prior art part, and its employed anchoring agent is cheap, anchored force is big, and is easy installation and reliable, reclaims easily.
Task of the present utility model is implemented in the following manner, and it comprises nut, pallet, anchor bar body, backing plate and nut etc.; Anchor bar body is the stock that all there is thread segment at two, and anchor bar body anchor rear is provided with pallet and nut, and its tail end head is square toes, anchor head section kink has plastic pipe, be fixed with the rapid setting cement powder stick on the plastic pipe external diameter, its termination is fixed with baffle plate and nut, and baffle plate and nut weld together.
The utility model has the following advantages compared with the prior art: the installation difficulty that it has overcome inverted wedge type anchor rod is big, shortcomings such as poor reliability.It only is made up of rapid setting cement powder stick and anchor bar body, pallet, baffle plate and nut etc., and it is simple in structure, makes easily, and simple installation is reliable, and anchored force is big, and anchored force can reach 3～6 tons/root according to the wall rock condition difference.The cost of its anchoring agent only is 30% of a resin anchor.Be easy to reclaim, its rate of recovery height, the parts of recoverable anchor bar body and anchor tail account for more than 90% of total cost.Can be widely used in the underground mining and the supporting of construction of tunnel, be particularly useful for the crossheading bolt support of mechanical coal mining work plane, remarkable in economical benefits.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail, as shown in Figure 1, it comprises nut 1, pallet 2, anchor bar body 3, plastic bushing 4, baffle plate 6 and nut 7,5th, hollow rapid setting cement powder stick, the 8th, anchor hole; Wherein anchor bar body 3 is stocks that all there is thread segment at two, and its anchor tail end head is a square spigot; Baffle plate 6 is fixing with nut 7 welding, and plastic pipe 4 is that duroplasts is made, and replaces sand net in the hollow rapid setting cement powder stick 5 with it, is beneficial to the rotation of anchor bar body.During use, coat the anti-embroidery of butter at the body of rod thread segment of anchor head, penetrate in the hollow rapid setting cement powder stick 5 of band plastic pipe 4 sheaths, spread an amount of butter again on screw thread, first-class baffle plate 6 and nut 7 are sent cement-roll and anchor head end into anchor hole 8 bottoms after the appropriateness immersion, impact rapid setting cement powder stick 5 tight with installing sleeve, make between powder stick and anchor hole wall and produce adhesion stress,, get final product at pack into pallet 2 and tighten of anchor tail with nut 1 so anchor head is anchored at anchor hole 8 bottoms.
When needs reclaim anchor pole, after backing out nut 1 and unloading pallet 2, be clipped in tail end square toes place with common spanner, oppositely turn and can draw off anchor pole 3 recovery repeated uses.
