Drainage hole forming construction method

The invention discloses a drain hole forming construction method. The method comprises the forming construction process of an auxiliary tool for drain hole forming construction on the basis that a construction frame body is not disassembled as a mounting and stress foundation. According to the auxiliary tool for forming construction of the drain hole, a stress foundation is obtained on an undisassembled construction frame body, a handle is driven to drive a gear to rotate, and a rack drives a drilling machine to conduct forming construction on a side slope to drill the drain hole; the problem that a protection frame cannot obtain a placement environment to provide stress to conduct drainage hole drilling construction is solved. 本发明公开了一种泄水孔成型施工方法，包括：使得泄水孔成型施工用的辅助工装以未拆卸施工架体为安装及受力基础对泄水孔的成型施工过程。利用泄水孔成型施工用的辅助工装在未拆卸施工架体上获得受力基础，实现驱动手柄带着齿轮旋转在齿条带着钻机对边坡进行成型施工钻出泄水孔，在未拆卸施工架体的施工环境下，解决了防护架无法获得放置环境进行提供受力来进行泄水孔钻孔施工的问题。
