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 bearing plate assembly for bracing of foundation pit, slope reinforcement and underground structure resistance to plucking anti-floating.
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, the general full-sleeve pore-forming mode pore-forming that adopts, the pore-forming anchor pole is 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.
The utility model content
The utility model is for above-mentioned the deficiencies in the prior art, a kind of bearing plate assembly that can be used in conjunction with drilling rod, reinforced anchor bolt is provided, this bearing plate assembly can be pushed in stratum by drilling rod, and be threaded with reinforced anchor bolt, and the bearing plate assembly has larger surface area, so increased the resistance to plucking drawing-resistant function of reinforced anchor bolt.
The technical solution of the utility model is achieved in that
A kind of bearing plate assembly, described bearing plate assembly comprises bearing plate, in the bearing plate center, is equipped with a joint, and 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.
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.
As preferably, the entrance of screw is the pilot hole with tapering.Arranging of pilot hole facilitates the head of reinforcing bar to be inserted in joint.
As preferably, on bearing plate along circumferentially evenly being provided with a plurality of through holes, along the edge of through hole to joint before extreme direction be bent to form and cut native cutter.The existence of through hole can make part soil therefrom pass, and has reduced drilling rod and bearing plate assembly suffered resistance in advancing, and the existence of cutting native cutter can rotary cutting soil, is beneficial to bearing plate and advances, and cement paste or cement flour and soil are stirred.
As preferably, be fixed with the projection be used in conjunction with in order to the transmission ear with the drilling rod front end when at least one and drilling rod are used in conjunction with on the plate face of the bearing plate near joint.Projection coordinates with the transmission ear is staggered, and the bearing plate assembly can be rotated with drilling rod.
Adopted the principle of the present utility model of technique scheme and the advantage had to be:
1, the reinforcing bar that the utility model and bearing plate assembly are used in conjunction with claims again reinforced anchor bolt, and the bearing plate assembly has larger surface area, so can improve the uplift resistance of reinforced anchor bolt; And joint can play the effect of plug while coordinating with drilling rod, screw is set on joint can be threaded with reinforced anchor bolt again, arrange on bearing plate and cut native cutter and also can play the effect of stirring soil, whole bearing plate modular construction is ingenious, can realize multiple use.Bearing plate assembly of the present utility model is applicable to all stratum except basement rock;
2, can be used as vertical resistance to plucking anti-floating pile, the scope of application has obtained further raising;
3, in construction, adopt the process of drilling rod precession to stir soil, make the curing compound such as cement paste or cement flour fully mix with soil, and again the bearing plate assembly is pushed in stratum in the time of the drilling rod precession, after drilling rod is advanced and is put in place, insert reinforcing bar at drill pipe bore again, reinforcing bar is threaded with the bearing plate assembly simultaneously, again drilling rod is extracted afterwards, the relation just contacted with the bearing plate assembly due to drilling rod, the previous thrust of drilling rod and the resistance of soil of just leaning on makes drilling rod and bearing plate assembly keep relatively-stationary position relationship, so, drilling rod can be extracted easily, and reinforcing bar and bearing plate assembly are stayed in stratum, the bearing plate assembly, reinforcing bar and be wrapped in the anchor pole surrounding notes cement paste or cement flour and cement-soil that form after the drilling rod blade stirs implant the stirring type anchoring pile in conjunction with the common column drill pipe bore that forms, thereby avoid the pore-forming anchor pole constructional difficulties that collapse hole causes in pore-forming, skyhook, slip casting process in the past.Drilling rod can be constructed again after extracting next time.
4, reinforced anchor bolt inserts and can guarantee the center of anchor pole at drill pipe bore implantation stirring type anchoring pile by drill pipe bore, saves pore-forming anchor pole in the past and installs on anchor pole medium-height trestle at the anchoring pile intermediate demand for guaranteeing anchor pole; And the cement-soil anchoring body that can be same anchor pole repeatedly repeats the whitewashing stirring, thereby improve the intensity of anchoring body, and can realize different cement mixing content constructions at the diverse location of same anchor as required, thereby save cement consumption, save the engineering time, the saving construction cost in the situation that guarantee same uplift resistance.
5, reinforcing bar can also apply prestressing force by bolt by end of anchor rod, adding screw thread, also can apply prestressing force by common mode, as hydraulic jack, or does not apply prestressing force and can do common bolt application, has increased the scope of application of reinforced anchor bolt.
