Above-mentioned pile press is exclusively used in holding type major diameter static pressure sinking pipe cast-in-place pile job practices of the present invention.
The holding type major diameter static pressure sinking pipe cast-in-place pile job practices, the embodiment step is as follows:
A: measurement and positioning;
B: pile press is in place;
C: shoe is in place;
D: lifting steel bushing pile tube pipe;
Above-mentioned steps D is for being that steel bushing pile tube pipe that the long end of 10m-20m has a screw thread lifts in the vertical through holes of pile clamping box 4 and places the top of shoe with the crane 5 of pile press with the single-unit length of diameter 600mm-800mm.
D1: steel bushing pile tube pipe and shoe gap are taked the sealing seal approach;
E: steel bushing pile tube pipe centering investigation;
Above-mentioned steps E checks the verticality of two mutually orthogonal directions of steel bushing pile tube pipe for using transit, and the perpendicularity deviation when first segment steel bushing pile tube pipe inserts should just can not carry out next step step after meeting the requirements greater than 0.5%.
F: pressure pipe;
Pressure pipe promptly starts with the folder stake cylinder of horizontally set on the pile clamping box 4, folder stake cylinder bar end is provided with jaw, jaw is clamped steel bushing pile tube pipe, according to required pressure-activated main piling cylinder 6 ' or start main piling cylinder 6 ', secondary piling cylinder 8 ' simultaneously, pile clamping box 4 is moved downward, thereby steel bushing pile tube pipe is pressed in the soil with the static pressure, immersed tube construction technology.
G: take over;
After being pressed into steel bushing pile tube pipe, if do not reach set depth, then need to connect second joint, the 3rd joint ... connect threadably successively behind the steel sleeve, at this moment pile clamping box 4 will be gone up a joint steel bushing pile tube pipe clamp firmly, with crane 5 next joint steel bushing pile tube pipe is sling in the actuating sleeve 70 ' that the vertical vertical through holes place that imports hydraulic gyration device 7 ', back is provided with, hydraulic gyration device 7 ' starts, and actuating sleeve 70 ' produces gyration and the nipple of next joint steel bushing pile tube pipe is screwed in last one saves the nipple of steel bushing pile tube pipe and be spirally connected.
H: pressure pipe again;
Unclamp a joint steel bushing pile tube pipe, start main piling cylinder 6 ' or start main piling cylinder 6 ', secondary piling cylinder 8 ' simultaneously, pile clamping box 4 is moved upward, reclamp next joint steel bushing pile tube pipe, steel bushing pile tube pipe is pressed in the soil with the static pressure, immersed tube construction technology.
I: stop pressure pipe;
After end pressure and stake reach the final pressure control criterion, stop pressure pipe.
J: place reinforcing cage;
The elongated configuration of the general employing of reinforcing cage, after reinforcing cage was put into the position, the top hung tight fixing with wire rope, prevented reinforcing cage bottom bend by pressure, and concrete is irritated to certain altitude, unclamps wire rope.
K: placing of concrete;
K1: after concrete spouting is finished, more than concrete, add the perfusion rubble, guarantee the steel pipe internal pressure to the face of land.
L1: tube drawing;
Tube drawing starts main piling cylinder 6 ', secondary piling cylinder 8 ', anti-top oil cylinder 1 ' after promptly clamping steel bushing pile tube pipe with pile clamping box 4 individually or simultaneously, and pile clamping box 4 is risen, and extracts steel bushing pile tube pipe from soil.
L2: anti-inserting;
Anti-insert be about to steel bushing pile tube pipe and extract certain-length after, utilize main piling cylinder 6 ', secondary piling cylinder 8 ' once more, steel bushing pile tube pipe inserted in the soil, to guarantee the concrete density of stake end concrete density and concrete pile.In 1 meter length of when tube drawing, extracting at first, should repeatedly instead insert, in the tube drawing process, not have the oil cylinder stroke of two main piling cylinders 6 ' instead to insert once.
L3: after whenever extracting a steel bushing pile tube pipe, carry out the uncoupling operation;
Uncoupling promptly utilizes hydraulic gyration device 7 ' to start, and actuating sleeve 70 ' produces the nipple that gyration screws out the nipple of next joint steel bushing pile tube pipe a last joint steel bushing pile tube pipe.
L4:, when only a surplus joint steel bushing pile tube Guan Wei extracts, interior block stamp is hung in steel bushing pile tube pipe be pressed on the rubble end face that is positioned at the pipe inner concrete if when subterranean layer is arranged.With the roof pressure power of increase pipe inner concrete, thereby increase the top concrete compactness, and reduce the undergauge that causes because of the soil layer side pressure.
In construction, also can adopt the high-frequency type bobbing machine with further raising concrete density.
In normal construction, body upper is provided with fixedly that shelf plays fixation, does not then need the uncoupling operation not disconnect head, and steel bushing pile tube pipe can up promote always and be up to 60 meters, reduces the time that disconnects.
This construction method advantage is as follows:
1, bearing capacity of single pile height. Holding type major diameter static pressure sinking pipe cast-in-place pile is by the carrying shape Belong to end and hold friction pile. Because adopting, this construction method embraces compressed steel sleeve pipe pile sinking, Static pressure pile driver can adopt higher pile driving pressure pile sinking and needn't worry to occur as quiet Press the phenomenon of PHC pile tube clip pile position pile body breakage. Higher pile driving pressure can Steel sleeve is run through or enter sandy soils, residual soil, severely-weathered rock stratum, effectively Guaranteed that pile pipe arrives the design supporting course. When constructing simultaneously all soil of stake and stake are held Local products are given birth to obvious compacted effect, thereby have obviously improved pile side resistance and stake end Resistance.
2, bearing capacity is directly perceived. Pile driving pressure is the concentrated expression of pile side resistance and end resistance, because of There are certain correlation in this pile driving pressure and static loading experiment result, and it is perpendicular that end pressure can be estimated single pile To bearing capacity.
3, meet environmental requirement. Static pressure pile-sinking has avoided employing diesel hammer or hydraulic hammer hammering to sink The noise that pipe produces, the construction site does not have the situations such as mud contamination yet.
4, anticorrosive. The concrete layer protection is arranged around the steel reinforcement cage behind the pile, avoided underground water Corrosion to reinforcing bar.
5, speed of application is fast. Adopt between the steel sleeve pile pipe to be threaded, execute-in-place is convenient, Short construction period, speed is fast.
6, pile quality is reliable. By taking to prevent in anti-plug, the pipe that the measures such as interior block stamp from guaranteeing Concrete density, thus pile quality guaranteed.
