In-pile jacking and pulling device and jacking and pulling method
The invention relates to an in-pile jacking and pulling device, which is used for jacking and pulling a cored pile body and comprises a traction piece, one end of the traction piece can be inserted into a pile core of the pile body and is clamped at the bottom of the pile body, and the other end of the traction piece is exposed out of the top of the pile body; the connecting piece is fixed to the end, exposed out of the top of the pile body, of the traction piece, and the connecting piece is provided with a jacking end for jacking; the jacking and supporting mechanism is arranged beside the pile body, the jacking and supporting end of the connecting piece is jacked and supported by the jacking and supporting mechanism, and the jacking and supporting mechanism is telescopic; the traction piece is inserted into the coring pile body, one end of the traction piece is clamped to the bottom of the pile body, the traction piece is fixed through the connecting piece, the jacking mechanism jacks the connecting piece upwards, the device is simple in structure, the jacking mechanism is high in precision, the pile body can be jacked and pulled in a small space through jacking from bottom to top, a large space and equipment such as a large crane are not needed, and the device is convenient to use. And potential safety hazards are avoided.
本发明涉及一种桩内顶拔装置，用于顶拔取芯后的桩体，包括：牵引件，所述牵引件一端可插入桩体的桩芯并卡接于桩体底部，另一端露出桩体顶部；固定于所述牵引件露出桩体顶部的一端的连接件，所述连接件有供顶撑的顶撑端；设置于桩体旁的顶撑机构，所述顶撑机构顶撑于所述连接件的顶撑端，所述顶撑机构可伸缩；在取芯后的桩体内插入牵引件，将牵引件的一端卡接于桩体底部，通过连接件固定牵引接，使顶撑机构向上顶撑连接件，该装置结构简单，顶撑机构精度高，且从下往上顶撑可以在较小的空间内顶拔桩体，不需要较大的空间和大型吊机等设备，避免了安全隐患。
