Reinforcing treatment method for concrete faced rockfill dam toe board upstream fractured rock stratum slope face
The invention discloses a reinforcing treatment method for a slope surface of an upstream broken rock stratum of a toe board of a concrete faced rockfill dam, and belongs to the technical field of dam construction. Comprising the following steps: S1, anchoring between a wall bottom and a rock mass: anchoring between the wall bottom and the rock mass in a normal direction by adopting an anchor rod; s2, a concrete fitting slope retaining wall is constructed, specifically, concrete is constructed in a layered mode along with the gradient and the height of the slope, and a step type fitting slope retaining wall is formed; and S3, top protection net covering, wherein an active protection net is adopted to cover and wrap the slope rock mass needing to be protected at the position where steps are not prone to being arranged. According to the method, the overall stability of the slope fractured rock mass can be guaranteed, the construction difficulty can be reduced, and meanwhile the concrete pouring amount and the operation frame body erecting amount are saved.
本发明公开了用于面板堆石坝趾板上游破碎岩层斜坡面加固处理方法，属于大坝施工技术领域；包括以下步骤：S1、墙底和岩体之间锚固：在墙底和岩体之间采用锚杆进行法线方向锚固；S2、施工混凝土贴坡挡墙：随坡面坡度及高度分层施工混凝土，形成台阶式贴坡挡墙；S3、顶部防护网覆盖：不易设置台阶的部位，采用主动防护网覆盖包裹在所需防护斜坡岩体上。本发明，既能保证斜坡破碎岩体的整体稳定性，还能减小施工难度，同时还节省了混凝土浇筑量和操作架体搭设量。
