The invention discloses an impact-rotation deep underground diaphragm wall grooving machine for one-time wall cleaning and grooving, which is characterized in that when a drill rod of a high-frequency impact device is pressed against the top of a single drill bit transmission shaft, a cone drill is arranged at the bottom of a guide frame and corresponds to a residual triangular area which cannot be covered by two adjacent drill bits; axial pressure and rotation torque are applied to the cone drill through the weight of the guide frame and the hydraulic motor, and the special rock crushing function of the bit of the cone drill under the combined action of impacting, rolling and milling is achieved. When a drill rod of a high-frequency impact device abuts against the top face of a connection cross beam connected with a set of drill bit transmission shafts, a pair of horizontal milling rollers with the axes parallel to the groove wall are installed on the two sides of the connection cross beam of grouped drill bits hung and sliding on a guide frame bottom beam of the grooving machine and correspond to the positions of residual triangular areas of impact rotary drill bits. Impact of the high-frequency impact hammer on the top of the connecting cross beam is used as motive power, and the horizontal milling roller rotates to impact and crush residual rocks under the action of eccentric impact reaction force.
本发明公开了一次性清壁成槽的冲击‑回转深地下连续墙开槽机，当高频冲击装置的钎杆抵压在单个钻头传动轴顶部时，在导向框架的底部,对应相邻两个钻头覆盖不到的残留三角区设置有牙轮钻，通过导向架的压重以及液压马达给牙轮钻施加轴向压力和回转扭矩,发挥牙轮钻钻头特有的以冲击、碾压和铣削的复合作用进行岩石的破碎的功能。当高频冲击装置的钎杆抵压在连结一组钻头传动轴的联系横梁顶面时，在悬挂滑动于开槽机的导向框架底梁的分组钻头的联系横梁两侧,相应于冲击回转钻头残留三角区位置，安装有一对轴线与槽壁平行的水平铣削辊，以联系横梁顶部的高频冲击锤冲击为原动力，在偏心冲击反力作用下使水平铣削辊产生回转‑冲击破碎残留岩石。
