Anti-scouring structure of apron covering layer foundation and construction method
The invention relates to an anti-scouring structure of an apron covering layer foundation and a construction method. The invention aims to provide the anti-scouring structure of the apron covering layer foundation and the construction method. According to the technical scheme, the anti-scouring structure of the apron covering layer foundation is characterized in that a plurality of anti-scouring walls perpendicular to the water flow direction are arranged at the tail end of an apron in the water flow direction; the anti-scouring walls are arranged in a covering layer below the apron; and the top ends of the anti-scouring walls are inserted into the apron, and the bottom ends of the anti-scouring walls penetrate into bed rock below the covering layer. The construction method of the anti-scouring structure of the apron covering layer foundation is characterized by comprising the following steps of making construction preparation; constructing a groove section; preparing slurry; and checking the concrete pouring quality. The structure is suitable for a riverbed type hydropower station with large discharge per unit width, low water head and low Froude number.
本发明涉及一种护坦覆盖层基础防淘刷结构及施工方法。本发明的目的是提供一种护坦覆盖层基础防淘刷结构及施工方法。本发明的技术方案是：一种护坦覆盖层基础防淘刷结构，其特征在于：在所述护坦的水流方向末端设置有多道垂直水流方向的防淘墙，防淘墙设置于护坦下方的覆盖层内，该防淘墙顶端插入护坦中，底端深入覆盖层下方的基岩内。一种所述护坦覆盖层基础防淘刷结构的施工方法，其特征在于，包括以下步骤：施工准备；槽段建造；泥浆制作；混凝土浇筑质量检查。本发明适用于大单宽流量、低水头、低佛氏数的河床式水电站。
