Description

Foundation reinforced concrete bearing pile with multi-branch of bearing dish

The utility model relates to the reinforced concrete pile on a kind of building, bridge or various bases, and the forming tool of stake.

Several basis of the prior art, all exist bearing capacity little as piling, castinplace pile, root pile, explosion stake and laying foundation etc., poor stability, waste constructional materials, manpower, investment and the energy, especially to the soft basic unit of complexity, more can cause base integral to sink or uneven subsidence, bring difficulty for technically design and construction owing to pile quality is poor.

The purpose of this utility model is to propose a kind of steel concrete bearing peg that multiple-limb, multi-loadbearing set are arranged.And the forming tool scheme of this stake, to overcome weak point of the prior art.

The utility model is to realize like this.

Multiple-limb, load dish underpin concrete bearing peg comprise pile 1, have a plurality of on the pile and the angled branch's stake 2 of pile axis, and branch's stake can be per two external surfaces that are symmetricly set on pile.Also have one or more load dishes 3 on the pile.

The forming tool of multiple-limb, load dish underpin concrete bearing peg is beaten (pressure) device, branch's pile hole forming bifurcated pressurizer and force-bearing disc hole shaping arched depressor by the shaping of pile hole and is formed.The bifurcated pressurizer has a cylindrical cutter seat 30, and the seat bottom is connected with cutter holder 31; In the circular hole in the cutter seat, be equipped with flexibly connect together by cutter tail 32, power transmission ball 33, cutter 34 chisel that constitute, cutter holder 31 is led for the cutter head; The cutter holder also has the holder 35 of living, the supporting and the location of playing the cutter holder down.Arched depressor is to connect bow-shaped arm 40 by the clear ring 39 that is connected with pressure cylinder 38 on center pillar 37.

Pile hole in the forming tool of multiple-limb, load dish underpin concrete bearing peg is shaped, and to make (pressure) device be that a front end has cutting edge 11, cutting edge root to have to have the tubular type that can be provided with the plum blossom screw pile that fetches earth (as 24 among Fig. 3) in one or more groups symmetrical branch stake hole 13, the body to make (pressure) device on thickened wall 12, the body.

Pile hole in the forming tool of multiple-limb, load dish underpin concrete bearing peg is shaped, and to make (pressure) device also can be that a front end has cutting edge 21, cutting edge root to have to have on thickened wall 22, the body in one or more groups symmetrical branch stake hole, the body and is provided with the plum blossom screw pile 24 that fetches earth, and be externally connected with spiral beating (pressure) device of spiral leaf 23 at body.

Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.

Fig. 2 tubular type is played (pressure) device schematic diagram;

Fig. 3 is spiral to play (pressure) device schematic diagram;

Fig. 4 bifurcated pressurizer schematic diagram;

Fig. 5 arched depressor schematic diagram.

The pile 1 of multiple-limb, load dish underpin concrete bearing peg can be made up of the concrete floral tube 4 and the interior pile 5 in band branch stake hole according to the construction needs.In the concrete floral tube reinforcing bar is arranged, at an interior pile concrete placing.

Pile shaping in the forming tool of multiple-limb, load dish underpin concrete bearing peg is made (pressure) device and can be added conehead alive at the body Inner Front End.

Branch's stake bifurcated pressurizer in the forming tool can have only the single armed chisel.The both arms chisel that symmetry also can be arranged.In the single armed pressurizer, live and hold in the palm 35.

In the process of using technology of the present utility model to construct, need select for use tubular type (or spiral) pile hole to be shaped according to soil property and make (pressure) device, vertical or tilt to beat (pressures) device and squeeze into (or screw-in) stratum by designing requirement, and take out earth or extract earth out with slush pump with screw pile 24, if add conehead alive at pressure device body head, then can directly beat (revolving) and go out the pile hole, and need not fetch earth.Can the outside central siphon body in limit if the pile hole soil property of accomplishing fluently is solid, the construction in branch stake hole is carried out by the hole on the body in the limit, and the forming construction that carries out force-bearing disc hole with the position on body base; Easily the landslide soil property then can be extracted body earlier out, puts into the concrete floral tube 4 of the system of giving again, carries out the forming construction of branch stake hole and force-bearing disc hole at last.When doing branch stake hole, the cutter of bifurcated pressurizer 34 lets drive at branch stake hole on the depressor body, and (branch stake hole can be a horizontal plane symmetry two holes to be arranged, and two holes of the different other a pair of symmetry in position are arranged at another horizontal plane.) or aim at branch stake hole on the prefabricated concrete floral tube, on cutter tail 32, carry out punching press then, owing to link with wire rope between cutter tail, power transmission ball and the cutter head, so the cutter head can be raised at any time, and can in the hole of digging out, fill out reinforced material (hard rubbish, backfill etc.), thereby compacting branch stake hole around and the bottom.When doing force-bearing disc hole, arched depressor is put into along the pile hole, constantly push pressure cylinder 38 in the load dish position of design code (can do a plurality of trays on the pile post), and the rotation arched depressor, after turning over 180 °, bow-shaped arm 40 just stamps out force-bearing disc hole.The bow force-bearing disc hole also can use the bifurcated pressurizer, and change on the limit, press on the limit, obtains the effect the same with arched depressor.In the forming process of force-bearing disc hole, also can the limit flanging in the hole, fill out reinforced material, can also be with ramming head compacting bottom, to improve the compactness on stratum.After having finished the shaping of pile hole, branch stake hole and force-bearing disc hole, can in the hole, transfer reinforcing bar, carry out concrete spouting, thereby multiple-limb, load dish underpin concrete bearing peg are manufactured and finished.Also can give system for branch's stake, after branch stake hole is carried out, put into the bifurcated pressurizer and to give system branch stake, carry out the perfusion of pile at last again.

The utility model has the advantages that:

1, the utility model bearing pile is significantly improved than the stability on common carrying bearing capacity of pile, basis, has overcome the surplus heavy amount on basis, makes more more stable and stronger of basis.

2, this used construction material can be saved more than 50% than existing various bases, and saves manpower, the energy and investment, the reduction of erection time, reduces cost.

3, the forming tool of the utility model bearing pile is simple in structure, and use and maintenance is convenient. Particularly solved bifurcated and done the difficult problem in hole, made the technology of multiple-limb, force bearing disk strengthening of foundation concrete bearing pile be achieved and use.
