The invention discloses a construction method of an anchoring type high-altitude cantilever plank road. The method comprises the following steps: 1, surveying cliff rocks, performing engineering evaluation, providing engineering geology basis and necessary design parameters, and determining line selection design after safety is ensured; 2, designing a cantilever beam and a cast-in-place slab; 3, ensuring the thickness of a cast-in-place slab on the beam is not smaller than 15 cm, the concrete strength grade is not smaller than C30, third-level reinforcing steel bars with the interval being 10 cm and the diameter being 14 mm are arranged on main reinforcements on the lower portion of the slab, and distribution reinforcements are third-level reinforcing steel bars with the interval being 10 cm and the diameter being 12 mm; 4, pouring and compacting the breast boards; and 5, surveying and setting out. According to the construction method, the self strength of the rock mass is utilized, the construction technology of drilling holes in the rock mass and planting the steel bars into the anchor is adopted, the embedding depth of the root of the suspended outrigger is replaced, the workload of long-embedding-depth rock drilling and concrete pouring is omitted, concrete is greatly saved, and labor and time are saved.
本发明公开了一种锚固式高空悬臂栈道施工方法，包括以下步骤；步骤一、对崖岩勘察并作出工程评价，提供工程地质依据和必要的设计参数，确保安全后方可确定选线设计；步骤二、悬臂梁和现浇板设计；步骤三、将梁上现浇板厚度不小于15厘米，混凝土强度等级不小于C30，板的下部主筋配间距为10厘米、直径为14毫米的三级钢筋，其分布筋为间距为10厘米、直径为12毫米的三级钢筋；步骤四、栏板浇筑、筑实；步骤五、测量放线。本发明利用岩体的自身强度，采用在岩体上进行钻孔并钢筋植锚的施工技术，替换了悬空挑梁根部的埋置深度，省略了长埋深凿岩和浇筑混凝土的工作量，大大地节约了混凝土，省工省力。
