Annexation.
If wanting the steel pile casting 12 deeper place is driven underground, pile cover lengthening part 11 can also be set, by pile cover lengthening part
11 are arranged at the upper end of pile cover body 2, and are connected with pile cover body 2.So as to which vibration hammer 1 is accommodated in the upper end of pile cover lengthening part 11,
Specifically it see Fig. 7.
It is as follows using the detailed process of this pile cover：
Long some meters steel pile casting 12 is sent to after ground surface by vibration hammer 1, and the clamping jaw of hydraulic vibration driver 1 will be equipped with hydraulic pressure
The pile cover lower end of internal support device is plugged in the endoporus of steel pile casting 12, and pile cover lower surface is contacted with the upper surface of steel pile casting 12, hydraulic pressure
The downward exciting force of vibration hammer 1 is transmitted by two end faces of pile cover and steel pile casting 12, and the exciting force of level is by pile cover
The thrust transmission of briquetting 7.
The oil pipe that two of the top of pile cover body 2 are connected with hydraulic jack 21, by hydraulic quick coupling and ground
Hydraulic pressure pump truck is connected, and is just stretched out the piston rod of hydraulic jack 21 by the operation valve on hydraulic pressure pump truck.
Equipped with the oil control check valve being connected with the rodless cavity of hydraulic jack 21 and accumulator on hydraulic pressure pump truck, oil control check valve
Effect be locked out the pressure of the rodless cavity of hydraulic jack 21.During the downward exciting pile cover of vibration hammer 1, briquetting 7 is protected with steel
Micro deformation will occur for 12 inwall contact positions of cylinder.If without accumulator, therefore the thrust of briquetting 7 will diminish so that hydraulic vibration
The exciting force of hammer 1 can not be effectively passed on steel pile casting 12.It is mounted with after accumulator, can be to the rodless cavity of hydraulic jack 21
Pressure is supplemented, so as to ensure that briquetting 7 can be pressed on the inwall of steel pile casting 12 all the time.
It is described after vibration hammer 1 is by the construction requirement position under pile cover exciting to earth's surface, pass through the operation on hydraulic pressure pump truck
Valve just withdraws the piston rod of hydraulic jack 21, and the now cross push pedal of pile cover bottom is driven by hydraulic jack 21 and is lifted up,
Four push pedal projections 92 of cross push pedal drive four piece of first wedge 5 to be lifted respectively, the first wedge 5 is separated with the second wedge 6,
Removal is applied to the horizontal force on foundary weight, and briquetting 7 is to contract in the presence of extension spring, and such briquetting 7 just can be with steel pile casting 12
Wall departs from, and now hydraulic vibration driver 1 can just propose pile cover to ground.
To sum up, the hydraulic pressure inner bearing type stake that the application is provided utilizes the close connection of pile cover and steel pile casting inwall, by vibration hammer
Exciting force be effectively transferred to steel pile casting, and because the maximum outside diameter of the part between pile cover body two ends is protected less than or equal to steel
The external diameter of cylinder, so can enable vibration hammer directly by steel pile casting exciting to underground, so as to avoid existing vibration hammer in exciting
During steel pile casting, part steel pile casting can not be driven underground, and need the part unnecessary to every steel pile casting earth's surface to be cut again
Shortcoming, and this pile cover can on each steel pile casting Reusability, so both save material cost, again improve construction effect
Rate.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the utility model scope
Calmly, the those of ordinary skill in the utility model field does according to the disclosure above content any change, modification, belonging to right will
Seek the protection domain of book.
