Construction method for controllable anchor expansion structure of soft rock-soil layer branch plate
The invention discloses a construction method of a soft rock and soil layer branch plate controllable anchor expanding structure, the branch plate controllable anchor expanding structure comprises a shell, a connecting device, an oil pump, a measuring system, an oil cylinder, a piston, an extruding and expanding device and a drill bit, and a fixed support arm and a telescopic support arm are connected through a half gear, a connecting rod and a connecting rod plate; linear motion of the telescopic support arm is realized by the I-shaped slide block through the linear guide rail, and stretching of the squeezing and expanding arm is realized by driving the synchronous belt through the motor. The oil pump injects oil into the oil cylinder through the oil supply pipe, the piston is pushed to outwards push the squeezing and expanding support arm of the squeezing and expanding device, the squeezing and expanding support arm outwards bends to squeeze rock soil on the hole wall to achieve hole diameter expansion, similarly, the oil pump sucks oil from the oil cylinder through the oil return pipe to enable the piston to retract, and the squeezing and expanding device is recovered. The construction method comprises the following steps: (a) drilling to form a hole; (b) extruding and expanding for forming; (c) hole cleaning; (d) anchoring; (e) anchor hole grouting; the construction method is simple in process, high in work efficiency, low in cost, few in used equipment, advanced in technology and better in economic effect.
本发明公开了一种软弱岩土层支盘可控扩锚结构的施工方法，支盘可控扩锚结构包括壳体、连接装置、油泵、测量系统、油缸、活塞、挤扩器、钻头，固定支臂和伸缩支臂通过半齿轮、连杆和连杆板连接，再由“工”字型滑块通过直线导轨实现伸缩支臂的直线运动，通过电机驱动同步带实现挤扩臂的伸缩。油泵通过供油管向油缸注油，推压活塞向外推移挤扩器的挤扩支臂，挤扩支臂向外曲折挤压孔壁岩土而实现孔径扩张，同样，油泵通过回油管从油缸吸油使活塞回缩，挤扩器回收复原。施工方法包含以下步骤：(a)钻进成孔；(b)挤扩成型；(c)清孔；(d)下锚；(e)锚孔注浆；该施工方法工艺简单、工效高、成本低、所用设备少，技术先进、经济效果更优。
