It is specific to introduce；The technical program embodiment mainly includes mud exhauster, high-pressure hydraulic pump, valve, sealing plate, steel-pipe pile；The mud exhauster
The silt inside steel-pipe pile is excluded before pile pulling starts；The sealing plate is equipped with valve and for connecting the method for high-pressure hydraulic pump
It is blue；Silt inside the steel-pipe pile cleans out sealing welding at the top of rear sealing plate and steel-pipe pile, and does consolidation process to sealing plate,
Guarantee that sealing plate can bear sufficiently large upward top lift；The valve is used to be vented when high-pressure hydraulic pump fills the water in steel-pipe pile,
Valve is closed after exhaust；The high-pressure hydraulic pump fills the water in steel-pipe pile, and high pressure water, which acts on sealing plate, forms one upwards
Top lift, sealing plate drive steel-pipe pile move upwards.
Detailed description of the invention
Fig. 1 is first step schematic diagram of the invention；
Fig. 2 is second step of the invention, third step, the 4th step, the 5th step schematic diagram；
In figure: 1- mud exhauster, 2- steel-pipe pile, 3- water pump, 4- valve, 5- flange, 6- sealing plate, 7- pressure duct, 8- high pressure
Water pump.
Specific embodiment
Below in conjunction with attached drawing 1, attached drawing 2, technical solution in the embodiment of the present invention progress is clear, is fully described by,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on the technology of the present invention
The embodiment of embodiment, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
One, the step method of single steel-pipe pile is extracted:
The first step is filled the water by water pump 3 into steel-pipe pile 2 referring to Fig. 1, mud exhauster 1 is placed in inside steel-pipe pile 2,
The mixture removing of silt and water in steel-pipe pile 2 is finished using mud exhauster 1 simultaneously.
Second step, referring to Fig. 2, the sealing plate 6 and 2 top sealing welding of steel-pipe pile that are equipped with valve 4 and flange 5, and it is right
Sealing plate 6 does consolidation process, guarantees that sealing plate 6 is able to bear sufficiently large upward top lift.
Third step, referring to Fig. 2, high-pressure hydraulic pump 8 is made by 5 airtight connection of flange on pressure duct 7 and sealing plate 6
High-pressure hydraulic pump 8 is connected to steel-pipe pile 2.
4th step starts high-pressure hydraulic pump 8 to 2 internal water flooding of steel-pipe pile, to have at valve 4 referring to Fig. 2, opening valve 4
High-pressure hydraulic pump 8 is closed when water flows out, and closes valve 4.
5th step continues referring to Fig. 2, opening high-pressure hydraulic pump 8 to 2 internal water flooding of steel-pipe pile, sealing plate 6 will by one to
On top lift；With the increase of 2 internal pressure of steel-pipe pile, when the top lift that sealing plate 6 is subject to is greater than mud around 2 outer wall of steel-pipe pile
When soil is to its downward frictional resistance, steel-pipe pile 2 is under the drive of sealing plate 6, relative to ambient earth, steel-pipe pile 2 will generate to
On position it is mobile, by controlling the rate of water injection of high-pressure hydraulic pump 8, steel-pipe pile 2 is kept constantly to move upwards；When steel-pipe pile 2
When moving upward to certain altitude, steel-pipe pile 2 can directly be extracted with crane ship.
During above-mentioned four step, the high pressure water that 2 bottom of steel-pipe pile extrudes can form seepage flow along 2 outer wall of steel-pipe pile,
The combination of soil and steel-pipe pile 2 can be destroyed, so that 2 surrounding frictional resistance of steel-pipe pile be made to reduce；If 2 outside of steel-pipe pile is rubbed
It is excessive to wipe resistance, 2 outboard friction resistance of steel-pipe pile can be reduced by some corresponding ancillary technique means.
Two, the step method that more steel-pipe piles of lateral ties structure are arranged at top is extracted simultaneously:
Mud exhauster is placed in inside steel-pipe pile by the first step, is filled the water by water pump into steel-pipe pile, while using mud exhauster
Silt removing in steel-pipe pile is finished, removes as much as possible using mud exhauster or other ancillary equipments if needed (or rush
Pine) lateral ties member upper silt.
Second step sealing welding at the top of the sealing plate and each steel-pipe pile for being equipped with valve and flange, and does each sealing plate
Consolidation process guarantees that sealing plate can bear sufficiently large upward top lift.
Third step is equipped with a high-pressure hydraulic pump to every steel-pipe pile, by every high-pressure hydraulic pump by pressure duct with it is each
Flange airtight connection on sealing plate, is connected to high-pressure hydraulic pump with steel-pipe pile.
4th step opens the valve on each sealing plate, while starting high-pressure hydraulic pump to steel-pipe pile internal water flooding, to each valve
High-pressure hydraulic pump is closed when there are flowing out at door, closes valve.
5th step starts high-pressure hydraulic pump simultaneously again and continues to each steel-pipe pile internal water flooding, each sealing plate by one to
On top lift；With the increase of each steel-pipe pile internal water pressure, when the top lift that sealing plate is subject to is greater than around steel-pipe pile outer wall
When soil is to its downward frictional resistance, steel-pipe pile is under the drive of sealing plate, and relative to ambient earth, steel-pipe pile will generate upward
Position it is mobile, control the speed that each steel-pipe pile moves upwards by controlling the rate of water injection of each high-pressure hydraulic pump, keep
Each steel-pipe pile is synchronous to be risen, and when arriving certain altitude, is closed each high-pressure hydraulic pump, can directly be pulled out each steel-pipe pile with crane ship
Out.
The high pressure pile pulling technology waterborne that the present invention uses is not limited solely to high pressure water pile pulling, and compressed air etc. can also be used
A variety of media carry out various forms of high pressure pile pullings.
While there has been shown and described that technical solution of the present invention embodiment, for those of ordinary skill in the art and
Speech, it is possible to understand that these embodiments can be carried out with a variety of variations without departing from the principles and spirit of the present invention, repaired
Change, replacement and variant, protection scope of the present invention is defined by the appended claims and the equivalents thereof.
