Abstract
The utility model discloses a screw-like recyclable anchor rod so disposed that a steel pipe is welded with spiral triangle mesh wire fabric outside and welded with a tail bolt on tail portion, the tail bolt being provided with a nut, a pallet being mounted between the nut and the spiral triangle mesh wire fabric. The utility model can realize complete recycling and repetitive usage, and greatly reduces use cost. The utility model allows full-length anchoring, obtains strong anchoring force and efficient anchoring, and finds especial application to soft rock and aqueous geology conditions. The utility model enables a direct screw-in upon mounting without anchoring agent, which saves cost and solidification time of anchoring agent and greatly quickens construction.
Description
Technical field
The utility model relates to extractive industry roadway support field, specifically a kind of spiral recoverable anchor rod.
Background technology
At present, bolt support now has been widely used in colliery, mine working, deep foundation pit support, fields such as railway, highway slope protection.In temporary lining,, eliminate underground environmental pollution for energy-saving and cost-reducing, anchor pole reclaims just becomes urgent problem, the temporary supporting anchor pole of Shi Yonging in the past mostly can not recycled in its entirety, or the rate of recovery is low, can not realize full length fastening, anchoring effect is poor, needs the anchoring agent, and the set-up time is long, therefore, invention is a kind of can install the anchor pole simple, that the rate of recovery is high and seem particularly important.
Summary of the invention
Low for solving the common bolt rate of recovery, a difficult problem that can not full length fastening, the utility model provides a kind of spiral recoverable anchor rod.
The utility model is achieved in that steel pipe outside welding spiral triangle steel wire, and steel pipe afterbody welding afterbody bolt is installed nut on the afterbody bolt, tray between the triangle steel wire on nut and the steel pipe.
The beneficial effects of the utility model are: realized recycled in its entirety, can be repeatedly used, reduced use cost significantly; But full length fastening, the strong anchoring effect of anchored force is good, is particularly useful for soft rock and moisture geological conditions; Directly screw in during installation, do not need the anchoring agent, saved the expense and the anchoring agent setting time of anchoring agent, accelerated construction speed greatly.
Description of drawings
Be described further below in conjunction with accompanying drawing
Accompanying drawing is a structural representation of the present utility model
Among the figure 1, steel pipe 2, triangle steel wire 3, pallet 4, nut 5, afterbody bolt
The specific embodiment
As shown in the figure, spiral recoverable anchor rod is made up of steel pipe 1, triangle steel wire 2, pallet 3, nut 4 and afterbody bolt 5, steel pipe 1 outside welding spiral triangle steel wire 2, steel pipe 1 afterbody welding afterbody bolt 5, nut 4, tray 3 between the triangle steel wire 2 on nut 4 and the steel pipe 1 are installed on the afterbody bolt 5.
Add man-hour, steel pipe 1 afterbody cuts out the reinforcing welding groove, triangle steel wire 2 carries out crop to be handled, after afterbody bolt 5 is processed via the round steel rolled thread, cut out plumb joint again and afterbody cut flat processing, then with steel pipe 1 as matrix, triangle steel wire 2 twined by certain pitch be welded on the steel pipe 1, afterbody bolt 5 inserts in the steel pipe, welds together with steel pipe.
During use, on wall, hole earlier, again anchor pole is screwed in the hole, then pallet 3 is penetrated the anchor pole afterbody and make it to be attached on the wall, screw in anchor pole afterbody bolt 5 and fastening with nut 4; During recovery, reverse operating gets final product.
Claims (1)
1. a spiral recoverable anchor rod is characterized in that, steel pipe outside welding spiral triangle steel wire, and steel pipe afterbody welding afterbody bolt is installed nut on the afterbody bolt, tray between the triangle steel wire on nut and the steel pipe.
