Abstract

The utility model discloses a tension anchor rod, which comprises a rod body, a reinforcing body, a casing pipe and a spacer, wherein the rod body is arranged in the sleeve pipe, the truncated cone shaped reinforcing body is fixed at one end of the rod body, a segment of threads is formed at the other end thereof, the thread-borne end of the rod body is sleeved by the spacer and a screw nut in sequence, a plurality of jet orifices are formed on the casing pipe, and a plurality of arcs are arranged from a point A in the casing pipe to one end tip of the reinforcing body. The utility model has the advantages of simple structure and convenient operation, and is extensively applicable in channel construction, chain bridge construction, geotechnical construction, electrical installation, mines, etc.

Description

The pulling force anchor pole
Technical field
The utility model belongs to tunnel, mine and geotechnics supporting facility technical field, specifically is a kind of pulling force anchor pole.
Background technology
In recovery process such as tunnel, ground and mine, bolt support is the Surrounding Rock Control Technology that has support concurrently and reinforce two kinds of effects, compares with frame set and uses bolt support technology to have more remarkable economic efficiency.Anchor pole commonly used comprises the body of rod, anchoring body, support structure three parts, and wherein the body of rod is made up of muscle materials such as steel strand, reinforcing bar, special steel pipes; Anchoring body comprises injecting cement paste, ground tackle, sleeve pipe; The support structure comprises supporting plate, pad and nut.When adopting steel strand or high-strength steel tow to make rod body material, can claim anchor cable.This promptly is general anchor structure form.Traditional anchor pole can be divided into two types of full length fastening anchor pole and end anchorage anchor poles, existing full length fastening anchor pole material therefor all is rigid materials, the rock stratum of it and institute's anchoring is filled by all kinds of cementing agents and is bonded together, this class anchor pole mainly is the construction and installation complexity, long construction period, and the kinetic anchor hole that can't replenish the rock stratum changes, can not well solve the supporting problem in soft rock and large deformation navigation channel, and the end anchorage anchor pole mainly is to expand by the end of anchor pole or anchor cable, anchor pole is fastened on the rock stratum, deep, the anchoring rock stratum mainly is suspended on the hard rock stratum by supporting plate, therefore its anchorage effect power is single, in case tension force inadequately just can slippage, thereby causes anchor rod anchored inefficacy.Also have some anchor poles to address the above problem, but it adopts new material, make its actual effect instability, and the anchor structure complexity, the cost of production height, and then and be not suitable for the demand of extensively constructing.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, the pulling force anchor pole that anchoring is more stable.
The technical scheme of taking of the present utility model is: the pulling force anchor pole comprises the body of rod, sleeve pipe, adds solid and pad, the described body of rod is arranged in the sleeve pipe, the body of rod one end is fixed with truncated cone-shaped and adds solid, the other end is provided with one section screw thread, described pad is enclosed within on the body of rod threaded end, also be provided with nut after pad, several spray-holes are set on the described sleeve pipe, the A point is to being made up of several sections circular arcs by adding one end of solid end end on the sleeve pipe.
By pulling force anchor pole provided by the utility model, at least 3 sections on wherein above-mentioned circular arc; On nut be two, and be six square nuts.
The beneficial effects of the utility model are: the utility model adopts the solid that adds of truncated cone-shaped, makes can bear after the anchoring success various stronger to external broach, and draws tighter and tighter.The utility model is simple in structure, and is easy to operate, be suitable for occasions such as constructing tunnel, power equipment, communication equipment installation, cable bridge construction, rock construction, mine widely and use, and its construction period shortened the implementation cycle greatly within one day.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is that the utility model adds solid end cross section schematic diagram figure
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further: Fig. 1 is a structural scheme of mechanism of the present utility model, Fig. 2 is the solid end cross-sectional view that adds of the present utility model, as Fig. 1, shown in Figure 2: the pulling force anchor pole comprises the body of rod 1, sleeve pipe 2, add solid 3 and pad 5, the described body of rod 1 is arranged in the sleeve pipe 2, the body of rod 1 one ends are fixed with truncated cone-shaped and add solid 3, the other end is provided with one section screw thread, pad 5 is enclosed within on the body of rod 1 threaded end, overlap top nut 6 after the pad 5, several spray-holes 4 are set on the described sleeve pipe 2, and the A point is to being made up of several sections circular arcs by adding solid 3 one end end ends on the sleeve pipe 2.
In work progress, when injecting the anchoring agent in grouting layer 7, a part of anchoring agent meeting is flowed out from spray-hole 4, and is bonded together tightly with anchor pole object on every side.Inject the anchoring agent finish after every about more than ten minutes promptly when the anchoring agent is about to solidify, the past inner rotary at the body of rod 1 threaded place, band adds solid 3 one ends can force sleeve 2 to be divided into the part of several sections circular arcs to expansion all around, this moment the whole body of rod 1 and add solid 3 and can outwards shift out at leisure, until add just stop when solid 3 ends move to sleeve A point mobile outward.Add solid 3 and can force anchoring agent unnecessary in grouting layer 7 to be overflowed from spray-hole 4 in moving process, treat that afterwards the anchoring agent solidifies fully, whole anchoring process finishes.Be the round table-like solid 3 that adds because this pulling force anchor pole is provided with at the body of rod 1 one ends, thus anchoring finish after whole anchor pole from outside be a taper inward.When external pulling force spurs anchor pole, compare straight tube anchor pole, the resistance that this anchor pole produces is bigger, and external pulling force is big more anchor rod anchored tight more, and correspondingly its firm effect also is higher than common straight tube anchor pole significantly, thereby plays better anchorage effect.

Claims (3)
