Method and structure for heightening pouring type asphalt concrete core wall in low-temperature environment
The invention discloses a pouring type asphalt concrete core wall heightening method and structure in a low-temperature environment. The asphalt concrete core wall heightening structure is formed through pouring according to the following steps that firstly, a newly-added core wall is prepared; 2, a cleaning and leveling stage; 3, heightening the wall body; 4, softening the asphalt; fifthly, the dam body is piled up; and sixthly, a protection layer is installed. By means of the steps, on the basis of the built pouring type asphalt concrete core wall dam, the core wall is heightened, the newly-poured core wall and the old core wall are fully combined into a whole, and the unique connection mode of the top of the core wall and the wave wall is beneficial to dispersing the pressure of the wave wall to protect the core wall; according to the method, an existing structure can be fully utilized, the investment for heightening the core wall is saved, construction is convenient, construction can be rapidly completed in a low-temperature environment, the anti-seepage area of the dam can be increased, the anti-seepage effect of the whole dam is improved, the dead weight of the dam is increased along with the increase of the height of the core wall, and the stability of the dam is improved.
本发明公开了一种低温环境下浇筑式沥青混凝土心墙加高方法和结构，通过以下步骤浇筑成沥青混凝土心墙加高结构：步骤一：新增心墙准备阶段；步骤二：清理平整阶段；步骤三：墙体加高；步骤四：软化沥青；步骤五：坝体堆砌；步骤六：保护层安装。通过上述步骤在已建浇筑式沥青混凝土心墙坝的基础上，对心墙进行加高，新浇筑心墙与老心墙充分结合成一个整体，心墙顶部与防浪墙独特地衔接方式有利于分散防浪墙的压力保护心墙，该方法可充分利用已有结构、节省心墙加高的投资，施工方便，可在低温环境下快速完成施工，可以增加大坝的防渗面积，提高整个大坝的防渗效果，随着心墙高度的增加，大坝的自重增大，有助于改善大坝的稳定性。
