AI Technical Summary

Technical Problem

Existing drilling machines are unable to form rectangular anti-slide pile holes with horizontal cantilever in rock strata, and the low integration of drilling and slag removal equipment leads to low construction efficiency and high cost.

Method used

The drilling rig is suspended by cable and drills under its own weight. It combines horizontal and vertical drilling components for step-by-step drilling and is equipped with mixing, crushing, slag suction and grouting systems to achieve step-by-step drilling and simultaneous slag removal of rectangular pile holes.

Benefits of technology

It enables efficient drilling of rectangular pile holes for horizontal cantilever structures within rock strata, reducing construction steps, lowering costs, and improving construction efficiency and equipment integration.

Abstract

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深孔钻机,包括钻车以及经钻车上缆索所吊装的钻机,钻机包括管道固定架、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;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及驱动其作侧向移动的水平液压缸;竖向钻装置包括若干水平设置且组成矩形开挖面的圆柱钻组件。本发明的优点是:通过缆索和带绞刀、滚刀的可伸缩水平钻,实现深层岩体内钻挖水平悬臂结构的矩形桩孔,且钻机在缆索吊装下可依靠自重向下钻进,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。
