摘要
桐子林水电站导流明渠布置在右岸滩地上,明渠底板和左导墙基础为粉砂质粘土,属软弱基础,为满足结构要求,设计提出对该地层采用框格式连续墙进行基础处理。经过方案比选,"十"字形节点部位采用桩结构形式成槽施工,钢筋混凝土接头采用起拔导管与投放粘土袋相结合的施工方案,从施工效果和质量情况来看,所选方案符合框格式地下连续墙施工的特点,完全能满足工程的要求。
The diversion channel of Tongzilin Hydropowcr Station is arranged on the right bank beach, and the foundations of the channel bottom and the left guide wall are silty clay. To meet the requirements on structure, the foundation was designed to treat with panal-type continuous concrete wall. After the program comparison, the positions of cross-type node were trenched with pile structure, and the joints of reinforced concrete were constructed by pulling tremie and putting clay bags. The actual construction shows that the methods for constructing panel-type continuous wall meet the engineering requirements.
