Description
Technical field
The utility model relates to soil excavation, stability of slope and underground structure anti-floating resistance to plucking technical field, relates in particular to a kind of recoverable anchor pole for bracing of foundation pit, slope reinforcement and underground structure resistance to plucking anti-floating and the board-like anchoring pile of pressure-bearing.
Background technology
Plate brad supporting, bolt support are widely used in Foundation Pit Support Engineering and stability of slope engineering, the plate brad supporting cost is low, easy construction, but the length of soil nailing and stake diameter are less, and the equal power of resistance to plucking is little, is only applicable to general stratum, so the scope of application is less, often can not meet design requirement, and this kind of soil nailing can not well to apply prestressing force, uplift resistance not strong yet, can not well play a role; And the equal power of the length of anchor pole, diameter and resistance to plucking all is greater than soil nailing, but its cost is higher, and construction need be through first boring, after insert metal material, then slip casting two procedures, can not disposablely complete, and improved cost; And the easy collapse hole banketing, in weak soil, silt, flour sand, sand pebble layer, cause the pore-forming difficulty, generally adopts full-sleeve pore-forming mode pore-forming, pore-forming anchor pole easy collapse hole in pore-forming, skyhook, slip casting process, so difficulty of construction is high.
Due to the reinforcing bar as anchor pole or dowel generally because diameter is less, anchoring body is less than normal to the gripping force of reinforcing bar and dowel, can not give full play to the frictional force of anchoring body and the soil body, thereby anchoring pile length that need be longer can meet the requirement of anchor pulling force, has increased construction cost.Moreover, after existing anchor pole and cement-soil solidify pile, when construction finishes, after particularly as the part of supporting and protection structure, completing a protective function, usually can not reclaim, become underground obstacle, also waste to a certain extent material, increased cost, the recoverable anchor pole is the development trend of anchor pole.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, at first a kind of anchor pole of recoverable is provided, thereby can make it reuse, and reach and eliminate underground obstacle, cost-effective purpose, moreover, the utility model provide again a kind of operation simple, increase the anchor pulling force, cost is low and can apply the board-like anchoring pile of prestressed pressure-bearing; The utility model heads into the bearing plate assembly in stratum by drilling rod, the stirring vane of drilling rod front end is by cement paste or cement flour and soil body stirring formation cement-soil, and after drilling rod is drilled into and requires the degree of depth, implant anchor pole by drill pipe bore, anchor pole is threaded with the bearing plate assembly, and continuation limit water-spray type slurry or the stirring of cement flour limit when drilling rod exits, can make anchor pole both can guarantee when the centering support is not installed that anchor pole was in the middle of the cement-soil anchoring pile, and the collapse hole of avoiding pore-forming to cause, thereby solve in a pore-forming anchor bolt construction difficult problem; Simultaneously, whole section sheathed sleeve pipe of anchor pole, can make whole section of anchor pole under free state, and the bearing plate assembly becomes anchoring section, the side friction that is free segment is transferred to the bearing plate assembly, thereby can further improve the stability on the stratum such as side slope, bearing plate assembly and the soil body have larger contact area, and the anchor pulling force strengthens greatly more in the past; And anchor pole can be after completing its function, reversion breaks away from the bearing plate assembly, can in anchoring pile, extract anchor pole saving social resources.
The technical solution of the utility model is achieved in that
A kind of recoverable anchor pole, comprise anchor pole, on whole section anchor pole, is arranged with sleeve pipe, the anchor head of anchor pole afterbody and the head of anchor pole are exposed to outside sleeve pipe, two ends and the anchor pole of sleeve pipe are sealedly and fixedly connected, and leave gap between sleeve pipe and anchor pole, and the head of anchor pole is processed with screw thread.
As preferably, be coated with anti-friction agent on anchor pole.Thereby can guarantee anchor pole in anchoring pile in free state.Anti-friction agent can be selected lubrication oil.
As preferably, be filled with anti-friction agent in sleeve pipe.Filled anti-friction agent in sleeve pipe, guaranteed enough degree of lubrication, made anchor pole keep state fully freely in anchoring pile.
As preferably, the two ends of sleeve pipe are banded on anchor pole by iron wire.Sleeve pipe adopts iron wire to tie up, and method is simple, easy operating.
As preferably, described anchor pole is reinforcing bar or steel bar.Anchor pole adopts reinforcing bar, with low cost, the convenience of drawing materials.
The board-like anchoring pile of a kind of pressure-bearing, comprise bearing plate assembly and anchor pole as above, the bearing plate assembly is in the depths, stratum, anchor pole is plugged in stratum and with the bearing plate assembly and is threaded, anchor pole integral body is free segment, the bearing plate assembly and be wrapped in the anchor pole surrounding notes cement paste or cement flour and cement-soil that form after the drilling rod blade the stirs formation anchoring pile that combines.The bearing plate assembly forms anchoring pile as anchoring section and cement-soil, and the bearing plate assembly has larger surface area, has increased the anchor pulling force.
As preferably, described bearing plate assembly comprises bearing plate, be equipped with a joint in the bearing plate center, joint and bearing plate are fixedly linked, and the two ends of joint all are exposed to outside bearing plate, be provided with a screw arranged along the joint axis direction on the end face of joint rear end, the head of anchor pole screws in the screw of joint.Bearing plate has larger surface area, by drilling rod, is being pushed stratum after desired depth, then implants anchor pole at drill pipe bore, and anchor pole is connected with joint screw thread, connects more firmly, and bearing plate has played stronger resistance to plucking drawing-resistant function.
As preferably, take bearing plate as boundary, joint is divided into first half section joint and second half section joint, front end at first half section joint forms a drill bit, the second half section joint be one when being used in conjunction with drilling rod in order to seal the plug of drilling rod front end, screw is arranged on plug, and is provided with to guide the pod apertures of cement paste or cement flour in joint along the joint axis direction, position near drill bit on first half section joint offers the spray orifice communicated with pod apertures, and pod apertures also keeps connecting with screw.The second half section joint has played the effect of plug when advancing together with drilling rod, it is inserted in the drilling rod front end, effect one is to prevent that the soil body from entering and stopping up drilling rod from the drilling rod front end, effect two is to guarantee that bearing plate becomes one at rod boring and drilling rod, avoid slip casting or annotate powder losing efficacy, and bearing plate has played the limit stops effect, by the second half section joint restraint in the position of drilling rod front opening; Pod apertures is arranged in joint, thereby cement paste or cement flour in drilling rod can be sprayed from the joint front end.
As preferably, described spray orifice is one or two.Can be selected as required, when spray orifice is two, can makes whitewashing or dust more even.
