The specific embodiment
Below in conjunction with accompanying drawing embodiment to describing in further detail.
Fig. 1 to Fig. 8 illustrates an embodiment of the present utility model, and it comprises rectangle punching block pipe 15 open type, one side bottom band chimb; This chimb is made of a rectangle box-frame, the bottom outside welding one of the peristome of this rectangle box-frame and rectangle punching block pipe 15, thus form a chimb 11 that seals in a side of this rectangle punching block pipe.The length of this chimb 11 is set to 〉=and 800 millimeters.
Dispose the rectangle earther taking apparatus 18 of movable insertion in the rectangular tube of described rectangle punching block pipe 15, this earther taking apparatus is provided with extension bar.
One side of rectangle earther taking apparatus 18 is provided with bulldozing device.
This bulldozing device is by hydraulic pressure or compressed air-driven, and its soil-shifting direction of motion is horizontal direction, and perpendicular with the native direction of motion of carrying of rectangle earther taking apparatus 18.
The step of piling method is: remove miscellaneous fill or face of land crust layer in the stake position; Then, this open type rectangle punching block pipe 15 is sunk to soil layer, at this moment, weak soil is clamp-oned in this open type rectangle punching block pipe 15, adopts ground earther taking apparatus 18 as shown in Figure 2 or adopts general earther taking apparatus 17 shown in Figure 3; When this earther taking apparatus is promoted to these open type rectangle punching block pipe 15 tops with weak soil, described weak soil is released by bulldozing device.
Along with the degree of depth that fetches earth increases, adopt extension bar 16 shown in Figure 4 to be connected spreading, and release the soil body with earther taking apparatus 18; All get only up to these punching block pipe 15 top soil bodys; Then, insert cage of reinforcement in this open type rectangle punching block pipe 15, pour into concrete, this band chimb rectangular mold pipe 15 is extracted in vibration, promptly makes described band chimb rectangular filling pile.
Earther taking apparatus 18 is to be welded to form with a plurality of horizontal steel plates 2 for vertical long steel plate 1 by rectangle minor face all around, as shown in Figure 2; The middle part of horizontal steel plate 2 is provided with plate washer 3.
The both sides of horizontal steel plate 2 respectively are provided with movable turnover panel 4 of rectangular edges portion and the movable turnover panel 41 of rectangular central portion; The effect of the movable turnover panel 4 of rectangular edges portion is that the soil body that will be two straight flange portions of horizontal rectangle can enter earther taking apparatus by drop in leaf 4; Can seal the soil body when carrying soil again, thereby the soil body of two straight flange portions is taken out; The effect of the movable turnover panel 41 of rectangular central portion is that the soil body that will be horizontal middle transverse part can enter earther taking apparatus by drop in leaf 41; Can seal the soil body when carrying soil again, thereby the soil body of middle transverse part is taken out; The top is provided with top board 5, and this top board 5 is provided with top board mouth of connecting trough 51 and floor 6.
In rectangle punching block pipe 15 sank to soil layer and earther taking apparatus 18 insertion punching block pipes 15, the drop in leaf 4 in this earther taking apparatus was opened, and the soil body enters in the earther taking apparatus 18.When on put forward process because soil body deadweight effect, interior drop in leaf 4 and 41 is shelved on the plate washer 3, thereby the soil body is taken out in sealing soil body whereabouts.Because the long side direction of earther taking apparatus 18 is without hindrance unearthed place, shown in Fig. 2,3; The punching block pipe 15 that proposes among Fig. 1 is suitable for reading; Under the vibration force effect, be poured over outside the punching block pipe 15 from the trend both sides.
Insert earther taking apparatus 18 again and connect extension bar 16, extension bar 16 bottoms are provided with a plurality of turnover panel hasps 10, as shown in Figure 5; The base plate 14 and the earther taking apparatus top board 5 of extension bar 16 coincide, and turnover panel hasp 10 buckles in the described top board mouth of connecting trough 51 and is in buckling state.Turnover panel hasp 10 is fixed by bolts on the junction plate 9, and can freely rotate on extension bar 16 with base plate 14.
Static pressure sinks to.The middle part that pressure transmits bar 8 is provided with limiting plate 11, makes the pressure transmittance process evenly and not produce unstability.Upwards promote and take out the soil body; Enter once more in the rectangle punching block pipe 15; Again with second extension bar 16 base plate 14 and first extension bar top board 12 coincide, simultaneously turnover panel hasp 10 buckles in the top board notch 51 of first extension bar top board 12, both are in buckling state.With the above, take out the soil body.
When entering generality soil, need be replaced with second kind general native earther taking apparatus 17, as shown in Figure 4.General native earther taking apparatus 17 is to be connected to form for vertical long steel plate 1 and a plurality of horizontal steel plate 2 by a top board 5, all around I shape limit; Described top board 5 is provided with top board mouth of connecting trough 51 and floor 6; The both sides, bottom of the horizontal steel plate 2 of described bottom are provided with soil plug floor 7; General soil and pan soil enter general native earther taking apparatus 17 smoothly, can not fall when carrying soil.
Earther taking apparatus 18 is released the top grid soil body of described band chimb rectangle punching block pipe 15 outside the pipe by bulldozer; Earther taking apparatus promotes lattice, and bulldozer is about to this lattice soil body and releases, and has pushed away until the soil body and has got only.
After taking out the soil body in the punching block pipe of the present utility model, insert cage of reinforcement, pour into concrete, the punching block pipe is extracted in vibration, promptly makes first band chimb rectangular filling pile 60 as shown in Figure 8.
Then, the dotted line position as Fig. 8 sinks to band chimb rectangle punching block pipe 15.Second adjacent band chimb rectangular filling pile is to sink to band chimb rectangle punching block pipe at chimb concrete 1/2nd places of first band chimb rectangular filling pile, and 1/2nd and the soil body of this chimb concrete enters in the band chimb rectangle punching block pipe; Repeat above-mentioned operation, the chimb concrete of first band chimb rectangular filling pile combines before initial set fully with adjacent second band chimb rectangular filling pile, thus formation the utility model dry soil withdrawal meshing type rectangular injecting castinplace pile.
The utility model feature is castinplace pile employing band chimb square-section castinplace pile and dry construction and adopts earther taking apparatus and bulldozing device efficiently to carry soil and the release soil body, efficiency of construction height; Adopt extension bar can take out the deep soil body again, swift to operate, convenient; In addition, adjacent pile body interlock is continuous, no constuction joint, and more existing diaphragm wall has more the anti-permeability characteristics; Thereby it be a kind of efficient, high-quality can economize on resources again and the novel bored pile piling device and the piling method that reduce blowdown.
