Concrete dam foundation giant deep groove reinforcing structure and construction method
The invention discloses a structure for reinforcing a huge deep groove of a concrete dam foundation and a construction method. The method is suitable for hydraulic and hydro-power engineering. According to the technical scheme, the device comprises a bearing plate which strides the top of a deep groove, the bottom of the bearing plate is of an arched structure, the upper portion of the bearing plate is used for pouring a dam body, the two ends of the bearing plate are supported by bed rocks on the two sides of the deep groove, and a plurality of grouting holes are formed in the positions, corresponding to the deep groove, of the bearing plate; the upstream anti-seepage wall and the downstream anti-seepage wall are arranged on bed rocks on the upstream and the downstream of the deep groove respectively, are tightly attached to the upstream end face and the downstream end face of the bearing plate and are used for avoiding diffusion of grouting materials in the high-pressure consolidation grouting period, preventing seepage in the operation period and reducing the uplift pressure of the dam bottom; the grouting part is formed by curing a grouting material poured by a high-pressure consolidation grouting pipe and is located in a deep groove defined by the upstream anti-seepage wall, the downstream anti-seepage wall and the bearing plate; and the backfill part is formed by curing a backfill material poured by the backfill grouting pipe, is positioned in the arched structure at the bottom of the bearing plate, and is connected with the grouting part into a whole.
本申请为一种混凝土坝基础巨型深槽加固的结构及施工方法。适用水利水电工程领域。技术方案包括承载板，跨设在深槽顶部，底部呈拱形结构，上部用于浇筑坝体，两端由深槽两侧的基岩承托，承载板与深槽对应部位开设有若干灌浆孔，孔内预埋高压固结灌浆管以及回填灌浆管；上游防渗墙和下游防渗墙，分别设置在深槽上游和下游的基岩上，并且贴紧承载板的上游端面和下游端面，用于高压固结灌浆期间避免灌浆材料扩散、运行期防渗和降低坝底扬压力；灌浆部，由高压固结灌浆管灌注的灌浆材料固化而成，位于上游防渗墙和下游防渗墙以及承载板所围拢的深槽内；回填部，由回填灌浆管灌注的回填材料固化而成，位于承载板底部的拱形结构内，与灌浆部连接成一体。
