The specific embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
As Fig. 1～shown in Figure 5, 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 bottom rotary power head 3 again and enters in the 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;
Synchronously immersed tube with revolve that to take native process be such: bottom rotary power head 3 drives steel pipes 1 spinning sinking pipe, the soil body that enters steel pipe 1 is transferred to pull out by auger stem 6 dextrorotations of last rotary power head 2 connections, and the soil outlet 9 that the soil body is brought to down 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 sinks to soil layer synchronously; 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 steel pipe 1 welding fixing; This sleeve pipe periphery is provided with the T-slot of being made up 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;
After whole soil bodys were got only in the steel pipe, a cleaning stake hole was inserted reinforcing cage 21 then, is poured into concrete 22, pulls out steel pipe 10 in the rotation and goes out ground with standard paragraphs pipe 20, namely finishes the synchronous immersed tube of steel pipe retaining wall of the present utility model and revolves and dig cast in place pile 23;
The utility model is fundamentally eliminated the pollution of borehole wall-protection mud, is to dig the castinplace pile that dried soil extracting process is constructed with the complete long steel pipe retaining wall of stake and with synchronous immersed tube with revolving.
The pile step of present embodiment is:
The first step, the bottom of bottom rotary power head 3 is connected with union 7, this union socket steel pipe 1 suitable for reading, last rotary power head 2 connects auger stem 6, and this auger stem enters the pore of steel pipe 1, passes bottom rotary power head 3 again, enter in the steel pipe 1, in place in design stake position;
Second step, following 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 last rotary power head passes down rotary power head 3 and enters in the 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 be interrupted and pull out, the soil body in this steel pipe arrives down the soil outlet 9 of rotary power head and discharges; To taking over the position, the auger stem that is connected with last 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 with following rotary power head bottom breaks away from the suitable for reading of steel pipe 1;
In the 3rd step, the standard paragraphs pipe box is gone into 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 the 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 be interrupted and pull out, the soil body in steel pipe 1 and the standard paragraphs pipe 10 arrives soil outlet 9 positions of bottom rotary power head 3 and discharges, and continues steel pipe 1 and standard paragraphs pipe 10 spinning underground layers are stopped until the designing requirement degree of depth;
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, in steel pipe 1 and standard paragraphs pipe 10, insert reinforcing cage 21, fill concrete 22; The union 7 socket standard paragraphs pipes 10 of the bottom of bottom rotary power head 3 suitable for reading, 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 rotation, driving down again, the joint steel pipe rotates, if full stake is long 4 section headers are arranged, go up relatively can drive after the 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 behind 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 descend significantly, this steel pipe all can be extracted ground with very little uplift force, namely finish the synchronous immersed tube of the complete long steel pipe retaining wall of stake and revolve the castinplace pile that takes soil.
