Piling system and construction method for building pile foundation construction
The invention discloses a piling system for building pile foundation construction. The piling system comprises a pile pressing seat capable of moving up and down, and a pile positioning groove is formed in the lower side of the pile pressing seat; the upper end of the pile pressing seat is fixedly connected with a pair of gravity hammer guide columns extending upwards, and the gravity hammer moves up and down under the guidance of the gravity hammer guide columns; the device further comprises a gravity hammer acceleration mechanism which can lift the gravity hammer to a preset height to be released, and the gravity hammer acceleration mechanism accelerates the gravity hammer in the free falling process after the gravity hammer is released. The gravity hammer is simple in structure, the descending acceleration of the gravity hammer is larger than the gravitational acceleration, and therefore the acceleration effect on the gravity hammer is achieved.
本发明公开了一种建筑桩基施工的打桩系统，包括能上下位移的压桩座，压桩座的下侧有桩柱定位槽；压桩座的上端固定连接有一对向上延伸的重力锤导向柱，还包括重力锤，重力锤在重力锤导向柱的导向下上下位移；还包括重力锤加速机构，重力锤加速机构能将重力锤抬升到预定高度释放，且在重力锤释放后的自由下坠的过程中对重力锤进行加速；本发明的结构简单，使重力锤的下降加速度要大于重力加速度，从而起到对重力锤的加速作用。
