Pile clamping device for vibrating and sinking offshore wind power single pile foundation through vibratory hammer
The invention discloses a pile clamping device for vibration sinking of an offshore wind power single pile foundation through a vibration hammer. The pile clamping device comprises a top clamp and a bottom buckle plate. The top clamp comprises a vibratory hammer clamping part and a buckle plate connecting part; the outer diameter of the vibratory hammer clamping part is matched with the width of a clamping jaw of the vibratory hammer; the pinch plate connecting part comprises an inner ring, a top plate and an outer ferrule; a plurality of through holes are formed in the surface of the top plate; the bottom buckle plate comprises a clamping sleeve and a supporting ring; a plurality of through holes are formed in the top surface of the clamping sleeve; the inner diameter of the supporting ring is matched with the outer diameter of the top of the single-pile foundation. A plurality of center hole jacks are installed on the top plate; the top clamp is placed on the top face of the pile top flange, the bottom buckle plate is arranged on the top of the single pile foundation in a sleeving mode, and the clamping sleeve is inserted into an annular groove formed by the inner wall of the outer ferrule, the outer wall of the inner ring and the top plate. After the pull rod sequentially penetrates through the penetrating hole, the through hole and the center hole jack, the base plate and the nut are sequentially installed on the pull rod. The device can adapt to vibratory hammers of different models, and the deformation probability of the pile top flange can be reduced.
本发明公开了一种振动锤振沉海上风电单桩基础的夹桩装置，包括顶部夹具和底部扣板。顶部夹具包括振动锤夹持部和扣板连接部；振动锤夹持部的外径与振动锤的夹持钳口的宽度适配；扣板连接部包括内环、顶板和外套圈；顶板的表面上开设多个通孔；底部扣板包括卡套和托环；卡套的顶面上开设多个穿孔；托环的内径与单桩基础的顶部外径适配；将多个穿心式千斤顶安装在顶板上；顶部夹具放在桩顶法兰的顶面上，底部扣板套在单桩基础的顶部并将卡套插入由外套圈的内壁、内环的外壁以及顶板构成的环槽内；将拉杆依次穿过穿孔、通孔和穿心式千斤顶后，依次将垫板和螺帽安装在拉杆上。本发明不仅能适应不同型号的振动锤，还能降低桩顶法兰的变形概率。
