The invention relates to a construction method for non-blasting excavation of a rock wall beam. The construction method solves the problem that the excavation forming precision of a rock platform of the rock wall beam is difficult to guarantee. The construction method comprises the following steps of 1, lofting and designing a contour line on the rock platform formed by layered excavation in the early stage; 2, drilling a core hole around the designed contour line; 3, drilling a splitting hole; 4, after drilling of the splitting hole is completed, installing a hydraulic rock splitting rod in the splitting hole to split and strip the rock; and 5, deslagging.
本发明为非爆破开挖岩壁梁的施工方法，解决岩壁梁岩台开挖成型精度将很难保证的问题，其步骤如下：1、在前期分层开挖形成的岩石平台上放样设计轮廓线，2、在设计轮廓线周边钻取芯孔，3、钻劈裂孔，4、劈裂孔钻孔完成后，在劈裂孔内安装液压岩石劈裂棒，劈裂剥落岩石，5、出渣。
