Abstract
The utility model provides a double-end anchoring type anchor rod for anchoring underground engineering rock masses, which comprises a twisted anchor head on an anchor rod body and an anchor tail with a thread section, and is mainly characterized in that a gasket is fixed at a proper position of the anchor tail, when in use, a hollow rapid hardening cement cartridge is added on the left end surface of the gasket, then a tray is used for compressing rock walls on the end surface of an anchor hole, and then a nut is used for screwing, thus the whole bearing capacity of the anchor rod body can be increased; and the structure is simple, the manufacture is easy, the cost is low, and the use is convenient.
Description
The utility model relates to a kind of rock anchorage device of underground construction, especially a kind of anchor pole that is applicable to the mine pressure supporting.
The anchor pole of underground engineering support use at present, generally with end anchor formula and full anchor formula two big classes: (1) end anchor formula has rapid setting cement and resin explosive roll formula anchor pole etc., according to code requirement, the anchoring bearing capacity of anchor metal should be more than or equal to 4 tons, get final product with general φ 14mm round steel, but because its anchor rear is shaped on screw thread, so its actual carrying capacity does not reach 4 tons, in order to overcome this shortcoming, weld one section φ 16mm round steel that is shaped on screw thread at the anchor rear, or anchor tail thread segment is heat-treated, so its manufacturing process is just complicated, most on-the-spot φ 16mm round bars that directly use cause the waste of material; When stressed cast iron pallet damages of breaking easily when big, make the anchor pole inefficacy.General air placed concrete (slip casting) not in the coal road of exploiting field, concentrate in the tunnel in the coal seam that reaches 5～8 years in the length of service, the anchor pole easy-to-rust, its supporting capacity reduces.(2) full anchor formula anchor pole has reinforced concrete grouting rock bolt, tip anchor grouting behind shaft or drift lining anchor pole etc., because the restriction of construction technology and means, cement mortar is generally all annotated leakiness, thereby influences anchoring effect; Tip anchor grouting behind shaft or drift lining effect is better, but general nothing is pressed wind in the coal road of exploiting field, so the slip casting difficulty.When using the rod body material of high-elongation, the tensility of anchor pole can not be brought into play again well.
The purpose of this utility model is to design a kind of novel anchor rod in order to overcome above-mentioned weak point of the prior art, this new both-end anchoring type anchor pole is to increase a packing ring and the hollow rapid setting cement powder stick of a volume in the anchor portion, can improve the integrated carrying ability of anchor pole, to satisfy on-the-spot needs.
Task of the present utility model is implemented as follows, and it comprises pallet, nut, packing ring, anchor bar body, back-up ring etc., and anchor bar body is that anchor head is a twisted shape, and the anchor tail has the stock of thread segment.Being fixed with back-up ring, hollow rapid setting cement powder stick or resin will roll up in anchor head end appropriate location, is fixed with packing ring, hollow cement-roll, pallet and clamp nut in the appropriate location of anchor tail end.
Anchor bar body can also be made the stock that anchor head and anchor tail all have thread segment, fix a back-up ring at the anchor head suitable position, pack into successively more hollow rapid setting cement powder stick, packing ring and a clamp nut, symmetry is welded with two solder joints in anchor rear appropriate location, so that make packing ring location, packing ring of kink, hollow rapid setting cement powder stick, pallet and clamp nut successively again.
The utility model has following advantage compared with the prior art: it is by in the aperture being an anchor rear packing ring of installation and a rapid setting cement powder stick, constitute both-end anchoring type anchor pole, thereby overcome the above-mentioned drawback of end anchor formula anchor pole, prove through type approval test (rice surplus testing 500), this both-end anchoring type anchor pole is better than holding the formula anchor pole, can prevent body of rod corrosion, supporting effect is good, and it is the good anchor pole form of result of use in coal road or the soft-rock tunnel.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is another example structure figure 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 is made up of pallet 1, nut 2, packing ring 3, anchor bar body 4, back-up ring 5; The 6th, hollow rapid setting cement powder stick or resin explosive roll, the 8th, hollow rapid setting cement powder stick, the 9th, anchor hole.Wherein anchor bar body 4 is that head is a twisted shape, and its afterbody has the stock of thread segment, runs off for preventing the anchoring agent, is fixed with back-up ring 5 and packing ring 3 respectively in the appropriate location of anchor head and anchor tail, and packing ring 3 is fixed on apart from anchor tail end 180～250mm place; Pack on anchor head end back-up ring 5 right sides hollow rapid setting cement powder stick or resin explosive roll 6, pack on anchor tail packing ring 3 left sides hollow rapid setting cement powder stick 8, pallet 1 and clamp nut 2.During use,, throw into anchor pole in the anchor hole 9 and make pallet 1 be adjacent to the crag of anchor hole end face with hammer with after the cement-roll immersion.
As shown in Figure 2, it is another embodiment of the present utility model, it is made up of pallet 1, nut 2, packing ring 3, anchor bar body 4, back-up ring 5 and packing ring 7, wherein anchor bar body 4 is stocks that all there is thread segment at two, on the design attitude of anchor tail promptly apart from two solder joints of anchor tail end head 180～250mm place's balanced welding, so that make packing ring 3 location.The fixing back-up ring 5 in anchor head one end appropriate location, pack into successively hollow rapid setting cement powder stick 6, packing ring 7 are tightened with nut 2; At anchor tail end kink upper gasket 3 and with the solder joint location, reinstall hollow rapid setting cement powder stick 8, pallet 1 and fastening nut 2.During use, at first, hit the anchor tail with hammer then, make pallet 1 be adjacent to the crag of anchor hole end face in the anchor hole 9 of packing into after the cement-roll immersion, like this cement-roll in the anchor pole meet expansion behind the water and wedging in anchor hole.
