Pile extractor convenient to install and used for pile foundation uplift static load test
The invention discloses a convenient-to-install pile extractor for a pile foundation uplift static load test, which comprises an upper disc, a lower disc, a screw rod, a main beam, a high-pressure oil pump and a test pile, a jack is arranged at the bottom of the upper disc, one end of the jack is installed on the outer surface of the main beam, a support is arranged on the outer surface of the main beam, and the other end of the support is installed on the test pile. The steel bar of the test pile penetrates through the lower end of the steel bar connection converter and is anchored by an anchorage device. According to the technical scheme, the welding-free pile extractor is convenient to mount and dismount, mounting and dismounting are fast mainly through connection of the bolts and the anchorage devices, mounting of a traditional pile extractor is completed through welding generally needs several hours, dismounting is completed through cutting of reinforcing steel bars through a cutting machine, the whole length also needs more than one hour, and the welding-free pile extractor does not need electric welding, so that the welding-free pile extractor is very convenient to mount and dismount. Therefore, a professional welder is not needed, a power supply is not needed, and a fire work ticket does not need to be started.
本发明公开了一种便于安装的桩基抗拔静载试验用拔桩器，包括上盘、下盘、螺杆、主梁、高压油泵和试验桩，所述上盘的底部设置有千斤顶，所述千斤顶的一端安装在主梁的外表面，所述主梁的外表面设置有支座，所述试验桩的钢筋穿过钢筋连接转换器的下端用锚具锚固。本技术方案免焊接拔桩器安装拆卸方便，其主要通过螺栓和锚具连接安装拆卸很快，传统拔桩器安装是通过焊接完成通常需要几个小时，拆卸通过切割机切割钢筋完成，通长也需要一个小时以上的时间，免焊接拔桩器由于不使用电焊，所以不需要专业焊工，不需要使用电源，也不需要开动火作业票。
