The specific embodiment
As shown in Figure 3, four support anchoring piles 100 constitute whole support system, and guiding pile sinking platform 200 is bearing on four support anchoring piles 100.
Guiding pile sinking platform 200 comprises first floor platform 240 like Fig. 1, shown in 2, connects fixedly second layer platform 260 on the first floor platform 240.
Like Fig. 2, shown in 4, first floor platform 240 comprises the connecting frame 201 that is connected with second layer platform, connecting frame be provided with for 201 4 jiaos be used for support anchoring pile on the pylon 202 that is connected of guiding pile sinking platform guiding mechanism.Pylon 202 comprises the frame base 203 that is connected with connecting frame 201, connects vertical rack 204 on the frame base 203, is provided for the fixed mount 205 that is connected with the pile sinking platform guiding mechanism that leads on the vertical rack 204.The pile holding mechanism 300 that supports anchoring pile is fixed on the pylon 202; Like Fig. 1, shown in 3; Pile holding mechanism 300 is the bearings that comprise that the first floor platform is provided with, and the bearing level is provided with hydraulic cylinder, and pile holding mechanism 300 is arranged on a plurality of hydraulic pressure of holding tightly on the pylon 202 along circumference in the present embodiment; The upper surface of frame base 203 all is provided with identical last undersetting along circumference with the lower surface; Be respectively equipped with on the last undersetting and hold hydraulic jack up and down tightly, explain: evenly be provided with all to be connected with on 305, three upper brackets 305 of three upper brackets along circumference and hold hydraulic pressure 306 (shown in Figure 3) tightly with superstructure.
As shown in Figure 5; Second layer platform 260 comprises sub-truss 261, and sub-truss 261 tops are provided with link 263, and the sub-truss bottom is provided with down link 262; Last link 263 is provided with Longkou positioner 400, and following link 262 is provided with down the Longkou positioner.Last Longkou positioner is identical with following Longkou positioner 450 structures, is provided with along circumference and forms one group.As shown in Figure 3, in the present embodiment, how much steel pipe pile decided when how many groups of Longkou positioner were according to piling construction up and down; As shown in Figure 3, be provided with four groups in the present embodiment, all four Longkou positioners are set up and down, with the adjustment steel pipe pile along the cross direction.
