Reservoir bottom structure and construction method thereof
The construction method comprises the following steps that the elevation of a reservoir bottom foundation surface is determined, a first covering layer material higher than the reservoir bottom foundation surface is removed to form a reservoir bottom excavation area, and a second covering layer lower than the surface of the reservoir bottom foundation surface area is removed to form a reservoir bottom backfill area initial backfill foundation surface; filling materials are laid on the initial backfill foundation surface of the reservoir bottom backfill area to form a backfill area foundation; consolidation grouting is conducted on the area, located at the junction of the reservoir bottom excavation area and the reservoir bottom backfill area, of the backfill area foundation, and a consolidation grouting area is formed; a plurality of anchor bar piles are installed on the consolidation grouting area, and reservoir bottom anti-seepage panels with the sizes gradually reduced are sequentially laid on the bottom face of the reservoir bottom excavation area, the upper surface of the consolidation grouting area and the upper surface of the backfill area; and a water stop belt is installed between every two adjacent reservoir bottom anti-seepage panels, and the reservoir bottom structure is completed. The method is simple, special-shaped panels laid at the excavation and filling boundary are eliminated, and the stability of the reservoir bottom foundation is improved.
本发明公开了一种水库库底结构及其施工方法，包括以下步骤：确定库底建基面的高程，清除高于库底建基面以上第一覆盖层料形成库底开挖区，清除低于库底建基面区域表面的第二覆盖层形成库底回填区起始回填建基面；在库底回填区起始回填建基面上铺设填料形成回填区地基；在回填区地基上位于库底开挖区与库底回填区交界的区域进行固结灌浆，形成固结灌浆区；在固结灌浆区上安装多个锚筋桩，从库底开挖区的底面、固结灌浆区的上表面和回填区的上表面上依次铺设尺寸逐渐缩小的库底防渗面板；在相邻的库底防渗面板之间安装止水带，完成水库库底结构。该方法简单、消除了挖填分界线处铺设的异形面板，提高了库底地基的稳定性。
