Abstract
The utility model relates to a spike-shaped anchor rod for various geotechnical projects, such as a foundation ditch, a side slope, a tunnel and the like, in which reinforcement is needed. The spike-shaped anchor rod comprises an anchor rod body, and a plurality of supporting rods are radially distributed on the surface of the anchor rod body; and one end of each supporting rod is fixed on the anchor rod body, and the other end thereof is a free end. The supporting rods which are densely and regularly distributed (arranged like spikes) on the periphery of the anchor rod body can seize the rock-soil mass which is improved in slip casing and filled, thereby improving the anchoring force of the spike-shaped anchor rod in rock-soil layers.
Description
[technical field]
The utility model relates to a kind of spike anchor pole, is used for the reinforcement protection construction in various foundation ditches, side slope, tunnel isolith geotechnique journey.
[background technology]
In the reinforcement protection construction in foundation ditch, side slope, tunnel isolith geotechnique journey, adopt anchor pole very extensive, wherein the kind of anchor rod body is a lot, differs from one another, and corresponding construction method is basic identical.Existing anchor bolt construction generally is in the stratum after the boring, and anchor rod body is packed in the boring, cement paste or cement mortar is poured in the space between the body of rod and borehole wall by Grouting Pipe or anchor rod body centre bore carries out anchoring again.Existing anchor pole technology makes and has only localized voids or tight the hole week of anchor pole if be used in the weak soil layer contraction because of bolthole before the slip casting, though slip casting but can't form the column anchoring body around anchor pole, can only form lumps or slurry arteries and veins at each slurry outlet place, many lumps or slurry arteries and veins are by the body of rod, constitute the straight-bar upper edge body of rod and have the form of many melon shape slurries or lobate slurry, make all local distribution of bar that injecting cement paste be arranged, can't obtain enough anchored force, the security reliability of engineering is suffered damage.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of can strengthen the frictional resistance of anchor pole in rock-soil layer, thereby can significantly improve the spike anchor pole of anchoring effect.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
The spike anchor pole comprises anchor rod body, and described anchor rod body surface is radiation-like and is distributed with a plurality of poles; One end of described pole is fixed on the anchor rod body, and the other end is a free end.
The free end of described pole is fixed on the anchor rod body, outwards arches upward in the middle part.
Described anchor rod body front end is connected with conehead.
Connected mode between described conehead and the anchor rod body is to adopt welding or socket.
Described conehead tip is welded with an alloy body.
The shape of described alloy body is spheroid or polyhedron.
Advantage of the present utility model is: there is the barb-shaped spike to arrange pole on the anchor rod body, and when the body of rod is pushed in the soil layer hole, the one, many because of pole, many pole together support anchor pole weight play the multiple spot supporting body of rod, overcome the body of rod inclined to one side effect too down.The 2nd, many pole one ends are fixed on the anchor rod body, and other end elasticity is opened, and marks deep trouth at the hole wall downside when being unlikely in pushing the hole, overcome because of the body of rod to be absorbed in from drawing deep trouth serious quality problems of core shift downwards in boring.In addition, even the body of rod also can hook anchoring body because of the hangnail pole of body of rod upside to boring downside core shift, effectively guarantee the adhesion strength of anchor rod body and anchoring body.Form the pole that spike is arranged around the anchor rod body of the present utility model, even the slip casting operation can't form complete column anchoring body in bar week under the weak soil condition, only form melon shape or lobate slurry, also can be distributed in anchor pole irregular slurry on every side, effectively improve the anchored force of anchor pole by pole gripping.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model first example structure schematic diagram.
Fig. 2 is the utility model second example structure schematic diagram.
Fig. 3 is the utility model the 3rd example structure schematic diagram.
[specific embodiment]
First embodiment
See also shown in Figure 1ly, the spike anchor pole comprises anchor rod body 10, and its surface is radiation-like and is distributed with a plurality of poles 20; One end of this pole 20 is fixed on the anchor rod body 10, and the other end is a free end.Anchor rod body 10 can be welding, bind with the connected mode of pole 20, screw is stubborn connects, grafting with holes, and natural generation (as the bamboo branch) etc.
When anchor rod body 10 is pushed in the soil layer hole, because pole 20 quantity are many, the one, many pole 20 together support anchor rod bodies 10 weight, reach the effect of multiple spot supporting anchor rod body 10, the 2nd, many pole 20 1 ends are fixed on the anchor rod body 10, other end elasticity is opened, and is unlikely to mark deep trouth at the hole wall downside when pushing in the boring when reverse, thereby overcomes the undue quality problems of core shift downwards of the body of rod.In addition, even anchor bar body 10 also can hook anchoring body because of pole 20 hangnails of body of rod upside to boring downside core shift, guaranteed anchored force.
Second embodiment
See also shown in Figure 2ly, the anchor pole of this embodiment comprises anchor rod body 10, and its surface is distributed with a plurality of poles 20 radially; One end 21 of this pole 20 is fixed on the anchor rod body 10, and the other end 22 also is fixed on the anchor rod body 10, outwards arches upward in the middle part.
Present embodiment is identical with the first example structure major part, and the free end 22 of different is exactly pole 20 is close on the anchor rod body 10, can strengthen its anchored force in rock-soil layer equally.
The 3rd embodiment
What the 3rd embodiment was different with first embodiment is, the anchor rod body front end is connected with conehead 30, and as shown in Figure 3, the connected mode between conehead 30 and the anchor rod body 10 is to adopt welding or socket (grafting).
To special formation,, must connect conehead 30 at the anchor pole front end, and pour the stratum with the jump bit of greater impact power as stratum such as layer of sand, sand layer, boulder bed, sand pebble layer under water.
The principle of the anchor bolt construction success of band conehead 30 is: though sand pebble layer is closely knit hard, the shock energy that is hit under the immersion condition produces local liquefaction, and becoming is easy to be driven into.Can extrude the road when conehead 30 is met gravel pebbles before the anchor pole continues to be driven into.By forcing the spike anchor pole that is driven into, because of being driven into the pole 20 that resistance is big and have spike to arrange, the anchored force of anchor pole is obviously increased, even few slip casting, even slip casting does not have enough anchored force yet.
In addition, the present embodiment special cemented carbide body 40 of also burn-oning in conehead 30 tips, when conehead 30 is driven into and when meeting than bowlder stone or thin erratic boulder, can smash it and squeeze open fragment to forward play to the satisfactory degree of depth.The shape of alloy body 40 can be spheroid or cuboid, or other polyhedron.
