Description
Technical field
The present invention relates to Pile Foundation of Offshore Platforms plinth fields, and in particular to air pressure regulator in a kind of pile body of anti-slip stake.
Background technique
Ocean platform as production and living facilities are provided in the structures of one, drilling well, construction, observe, lead by collection transport
Boat is.Its pile foundation construction generally uses great diameter and long steel-pipe pile, and tubular pole is squeezed into sea along conduit by hydraulic pile hammer
Substratum.However during driving piles, when in the soft layer that steel-pipe pile encounters in the soil layer of ocean, due to end resistance and stake side
Frictional resistance reduces, and often slips a phenomenon.Slipping stake not only influences pile quality and bearing capacity of pile foundation, but also can make stake
Practical pile penetration and pile foundation design altitude generate large error, pile quality can also be impacted.And current oceanic winds
Electrical domain do not have can also effectively pre- anti-slip stake device.
Summary of the invention
In view of the above-mentioned problems in the prior art, the present invention provides air pressure regulator in a kind of pile body of anti-slip stake, the dresses
Setting can prevent to slip stake when steel-pipe pile injection soft clay layer by air pressure in adjusting pile body, so that bearing capacity of pile foundation is improved,
Guarantee pile quality, and can be recycled, engineering practicability is strong, and economic technology is feasible.
The following technical solution is employed by the present invention:
Air pressure regulator in a kind of pile body of anti-slip stake, including being mounted on the pile cover of steel pipe pile head, air intake valve, going out
Air valve, velocity strain meter, connection wire and controller；The air intake valve and the outlet valve are arranged in the pile cover
On, air intake valve and outlet valve are electrically connected by the connection wire and the controller；The velocity strain meter is arranged in institute
The lower end of pile cover is stated, and is electrically connected by the connection wire and the controller, for detecting the movement velocity of steel-pipe pile；
When velocity strain meter detects that the movement velocity of steel-pipe pile is accelerated, steel-pipe pile slips stake, controller Electronic control outlet
Valve is closed, and air intake valve is opened and squeezes into gas into steel pipe stake body；
When velocity strain meter detects that steel-pipe pile slips stake stopping, controller Electronic control outlet valve is opened, intake valve
Door stops inflating, and air pressure restores balance in steel-pipe pile pile body, so far prevents from slipping stake by adjusting air pressure completion in pile body.
Further, the air intake valve is in mutually to be symmetrical set on the pile cover with the outlet valve.
Further, the controller is equipped with air intake valve indicator light and outlet valve indicator light.
The working principle of the invention is:
Steel-pipe pile pile body is formed a closed sky by pile cover by air pressure regulator in a kind of pile body of anti-slip stake
Between, then the intracorporal air pressure of stake adjusted by air intake valve and outlet valve, when steel-pipe pile slips, the movement velocity of steel-pipe pile
Accelerate, when velocity strain meter detects that steel-pipe pile slips, pile hammer stops working, outlet valve closing, air intake valve
It opens and simultaneously squeezes into gas into pile body, gas pressure intensity increases in pile body at this time, to pile body one upward dynamic balance self gravity,
To inhibit steel-pipe pile to slip stake, when velocity strain meter detects that slipping stake stops, outlet valve is opened, and air intake valve stops
It inflates, air pressure restores balance in pile body, and piling work continues.
The invention has the advantages that:
It can prevent to slip stake when steel-pipe pile injection soft clay layer, to improve pile foundation by adjusting air pressure in pile body
Bearing capacity guarantees pile quality, and can be recycled that engineering practicability is strong, and economic technology is feasible.

Specific embodiment
The present invention is specifically described with reference to the accompanying drawing:
In conjunction with Fig. 1 to Fig. 3, air pressure regulator in a kind of pile body of anti-slip stake, the stake including being mounted on steel pipe pile head
Cap 1, air intake valve 2, outlet valve 3, velocity strain meter 4, connection wire 5 and controller 6；The air intake valve 2 and it is described go out
Air valve 3 is arranged on the pile cover 1, and air intake valve 2 and outlet valve 3 pass through the connection wire 5 and 6 electricity of controller
Even；The lower end of the pile cover 1 is arranged in the velocity strain meter 4, and is electrically connected by the connection wire 5 with the controller 6,
For detecting the movement velocity of steel-pipe pile 9；
When velocity strain meter 4 detects that the movement velocity of steel-pipe pile 9 is accelerated, steel-pipe pile 9 slips stake, 6 Electronic control of controller
Outlet valve 3 is closed, and air intake valve 2 is opened and squeezes into gas into 9 pile body of steel-pipe pile；
When velocity strain meter 4 detects that steel-pipe pile 9 slips stake stopping, 6 Electronic control outlet valve 3 of controller is opened, into
The stopping of air valve 2 is inflated, and air pressure restores balance in 9 pile body of steel-pipe pile, so far prevents from slipping stake by adjusting air pressure completion in pile body.
Further, the air intake valve 2 is in mutually to be symmetrical set on the pile cover 1 with the outlet valve 3.
Further, the controller 6 is equipped with air intake valve indicator light 7 and outlet valve indicator light 8.
When construction: being required first according to detail design, velocity strain meter 4 is mounted on 9 pile body of steel-pipe pile, then by steel pipe
Stake 9 is mounted on leading truck, fixes the pile cover 1 of the present apparatus in pile body upper end, then pass through connection wire 5 for velocity strain meter 4
It is connected with pile cover 1 and the connection between controller 6 and pile cover 1, pile hammer 10 starts to drive piles later, at this time 2 He of air intake valve
Outlet valve 3 is in opened condition；
When steel-pipe pile 9 squeezes into soft layer, steel-pipe pile 9 can slip stake, and velocity strain meter 4 detects steel-pipe pile 9
Subsidence velocity is greater than normal speed, and pile hammer 10 stops piling immediately, and controller 6 controls outlet valve 2 and closes at this time, intake valve
Door 3 is started to work, while being controlled air intake valve indicator light 7 and being lighted, and outlet valve indicator light 8 goes out, and starts to squeeze into the inside of pile body
Gas enhances the gas pressure intensity in pile body, so that steel-pipe pile 9 be inhibited to slip stake；
When velocity strain meter 4 detects that slipping stake stops, 6 Electronic control outlet valve 3 of controller is opened, air intake valve 2
Stopping is inflated, while the outlet valve indicator light 8 of the control of controller 6 thereon lights, and air intake valve indicator light 8 goes out, work of driving piles
Continue.
