两河口水电站大坝砾石土心墙雨季施工措施

Construction measures of gravel soil core wall of Lianghekou Hydropower Station in rainy season

两河口水电站位于川西高原气候区,雨季较长,降雨突然且雨量大,制定雨季施工措施非常必要。本文在分析施工区历年降雨数据的基础上,针对雨季施工的特点和难点,提出了适应性较强的雨季施工控制措施,在确保心墙填筑质量的同时,满足了施工进度的要求,施工效果良好,可为其他工程雨季施工提供借鉴。

Lianghekou Hydropower Station is located in the climatic region of Western Sichuan Plateau. The rainy season is longer, rainfall is sudden and heavy, and it is very necessary to fornmlate construction measures for the rainy season. More adaptive control measures for construction during rainy season are proposed based on the analysis of rainfall data over the years in the construction area in view of characteristics and difficulties of construction during rainy season. The quality of core wall filling is ensured. Meanwhile, it meets the requirements of the construction schedule, and the construction effect is good, thereby providing reference for construction of other projects during rainy season.
