Step-by-step rectangular shallow hole drilling machine provided with horizontal cantilever and suitable for rock stratum
The step-by-step rectangular shallow hole drilling machine comprises a drill carriage with a vertical drill rod, and a rock slag treatment mechanism, a horizontal drilling assembly and a vertical drilling device are sequentially arranged at the lower end of the vertical drill rod; the rock slag treatment mechanism comprises a stirring device, a crushing device, a slag suction system, a slag discharge system and a grouting system; the stirring device comprises a stirring box and a stirring mechanism; a slag suction opening formed in the stirring box is connected with a slag suction system, and a slag discharge opening is connected with a slag discharge system; the grouting system is communicated with the interior of the horizontal drilling assembly and the interior of the vertical drilling device; the horizontal drilling assembly comprises a horizontal drilling device and a horizontal hydraulic cylinder for driving the horizontal drilling device to move horizontally; the vertical drilling device comprises a plurality of cylindrical drilling assemblies forming a rectangular excavation face. The method has the advantages that through the drill rod and the telescopic horizontal drill with the reamer and the hob, a rectangular pile hole of a horizontal cantilever structure is drilled in a shallow rock mass; rock is subjected to secondary crushing through the crushing box and can be better discharged out of the pile hole, and the slag discharging pipe is prevented from being blocked.
本发明公开了一种适应岩质地层的分步式带水平悬臂的矩形浅孔钻机，包括具有竖向钻杆的钻车，竖向钻杆的下端依次设置有岩渣处理机构、水平钻组件及竖向钻装置；岩渣处理机构包括搅拌装置、破碎装置、吸渣系统、排渣系统及注浆系统；搅拌装置包括搅拌箱和搅拌机构；搅拌箱上所设置的吸渣口连接吸渣系统、排渣口连接排渣系统；注浆系统接通至水平钻组件内以及竖向钻装置内；水平钻组件包括水平钻装置以及驱动其水平移动的水平液压缸；竖向钻装置包括若干组成矩形开挖面的圆柱钻组件。本发明的优点是：通过钻杆和带绞刀和滚刀的可伸缩水平钻，实现浅层岩体内钻挖水平悬臂结构的矩形桩孔；岩石经破碎箱二次破碎，能更好地排出桩孔，防止排渣管堵塞。
