Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 5, the present embodiment adopts following structure particularly: it comprises the top rotary power head 2 that is connected with auger stem 6, and this auger stem 6 in a tubular form and the clockwise direction rotation; This auger stem 6 passes again bottom rotary power head 3 and enters in steel pipe 1; The bottom of this bottom rotary power head is provided with union 7, this union 7 and steel pipe 1 upper end socket, and this steel pipe 1 drives rotation in the counterclockwise direction by bottom rotary power head 3, as shown in Figure 1;
Synchronous immersed tube with revolve that to take native process be such: bottom rotary power head 3 drives steel pipe 1 spinning sinking pipes, the soil body that enters steel pipe 1 is transferred to pull out by auger stem 6 dextrorotations of upper rotary power head 2 connections, and the soil outlet 9 that the soil body is brought to lower rotary power head 3 is discharged;
In order to realize the length requirement of different castinplace piles, steel pipe 1 can be connected with standard paragraphs pipe 10 by linkage, with spreading steel pipe 1, and synchronously sinks to soil layer; This linkage comprises sleeve pipe 11 and the interconnective standard paragraphs pipe 10 of steel pipe 1 bottom, and this sleeve pipe is provided with mounting flange 15 and reinforcing rib 16, and this mounting flange is used for being welded and fixed with steel pipe 1; This sleeve pipe periphery is provided with the T-slot that is comprised of vertical slot 13 and translot 14, and this T-slot top is provided with central small hole 4, and this central small hole and vertical slot 13 centers coincide;
Described standard paragraphs pipe 10 upper ends are provided with rectangle projection 8, and the width of this rectangle projection 8 matches with the width of vertical slot 13, and the height of this rectangle projection 8 matches with the height of translot 14;
Insert the vertical slot 13 of sleeve pipes 11 when the rectangle projection 8 of standard paragraphs pipe upper end, then, along with sleeve pipe 11 rotations of steel pipe 1, rectangle projection 8 namely enters translot 14 and reaches the purpose that standard paragraphs pipe 10 is connected with steel pipe 1; Make bottom rotary power head 3 pass through steel pipe 1 transmitting torque to standard paragraphs pipe 10, also namely realized the purpose of spreading steel pipe 1.
Be provided with location small salient point 5 below rectangle projection 8 center lines, the effect of this location small salient point 5 is the centers that show rectangle projection 8, when steel pipe 1 and standard paragraphs pipe 10 must separate when extracting from interface, need only aim at the small salient point 5 of central small hole 4 and the standard paragraphs pipe rectangle projection of bottom of steel pipe vertical slot on top on a vertical line, be the rectangle projection in the center of vertical slot, steel pipe 1 and standard paragraphs pipe 10 can be extracted from interface.
After in steel pipe, whole soil bodys are got only, clear up a hole, then insert reinforcing cage 21, pour into concrete 22, pull out steel pipe 10 in rotation and go out ground with standard paragraphs pipe 20, namely complete the synchronous immersed tube of steel pipe retaining wall of the present invention and revolve and dig cast in place pile 23:
The present invention fundamentally eliminates the pollution of borehole wall-protection mud, is to dig the castinplace pile that dried soil extracting process is constructed with the long steel pipe retaining wall of full stake and with synchronous immersed tube with revolving.
The pile step of the present embodiment is:
The first step, the bottom of bottom rotary power head 3 is connected with union 7, and this union is socketed the suitable for reading of steel pipe 1, upper rotary power head 2 connects auger stem 6, and this auger stem enters the pore of steel pipe 1, then passes bottom rotary power head 3, enter in steel pipe 1, a position is in place designing;
Second step, lower rotary power head 3 drive steel pipes 1 are rotated in a clockwise direction and sink to soil layer, simultaneously, the auger stem 6 that is connected with upper rotary power head passes lower rotary power head 3 and enters in steel pipe 1, synchronously be rotated in a clockwise direction, the soil body that enters steel pipe is upwards raised by this auger stem or is interrupted and pulls out, and the soil body in this steel pipe arrives the soil outlet 9 of lower rotary power head and discharges; To taking over the position, the auger stem that is connected with upper rotary power head is extracted the suitable for reading of steel pipe 1 with steel pipe 1 spinning underground layer in continuation, and the union 7 that is connected bottom lower rotary power head breaks away from the suitable for reading of steel pipes 1;
In the 3rd step, the standard paragraphs pipe is inserted in the suitable for reading of steel pipe 10; Top rotary power head 2 connects auger stem 6, this auger stem passes bottom rotary power head 3, enter in steel pipe 1 and standard paragraphs pipe 10, be rotated in a clockwise direction, the soil body that enters steel pipe 1 is upwards raised by auger stem 6 or is interrupted and pulls out, the soil body in steel pipe 1 and standard paragraphs pipe 10 arrives the soil outlet 9 positions discharges of bottom rotary power head 3, continues steel pipe 1 and standard paragraphs pipe 10 spinning underground layers, until the designing requirement degree of depth stops;
in the 4th step, top rotary power head 2 connects auger stem 6, and this auger stem 6 is extracted from the suitable for reading of steel pipe, and the union 7 of the bottom of bottom rotary power head 3 breaks away from the suitable for reading of standard paragraphs pipe 10, then, insert reinforcing cage 21 in steel pipe 1 and standard paragraphs pipe 10, fill concrete 22, the union 7 of the bottom of bottom rotary power head 3 is socketed the suitable for reading of standard paragraphs pipes 10, rotary power head 3 drives steel pipe and alternately rotates along clockwise direction with counterclockwise, because each steel pipe section header leaves 20 centimetres of swing offsets, after going up most 20 centimetres of displacements of joint steel pipe rotary, driving lower joint steel pipe rotates again, if full stake is long, 4 section headers are arranged, can drive after relatively upper joint stake must have (4-1) * 20=60 centimetre and descend the joint steel pipe most, original friction of rest power becomes to move frictional resistance after swing offset, rotary power head 3 drives standard paragraphs pipe 10 and rotatablely moves with steel pipe 1 alternating direction, make this steel pipe and the frictional resistance of soil property on every side significantly descend, this steel pipe all can be extracted ground with very little uplift force, namely complete the synchronous immersed tube of the long steel pipe retaining wall of full stake and revolve the castinplace pile that takes soil.
