摘要
以位于赣江下游的药湖联圩电排站工程为例,在概述工程施工导流标准、导流方式的基础上立足当前施工条件及机械设备配置,在充分考虑导流围堰堰体结构稳定性及可靠性的基础上对导流围堰防渗结构型式优化设计进行探讨,并从围堰结构、基本参数、实施思路,技术优劣势等方面对原围堰方案与优化方案进行了对比。结果表明,优化后的导流围堰将黏土心墙和上游过渡层等附属结构全部拆除,改用围堰上游土工膜防渗的结构形式,施工过程大大简化,防渗效果增强。
Taking the Yaohu Lianwei Hydropower Station in the lower reaches of the Gan River as an example, based on the current construction conditions and equipment allocation, the construction diversion standards and diversion modes of the project are outlined.On the basis of considering the structural stability and reliability of the diversion cofferdam, this paper discusses the optimum design of the anti-seepage structure of the diversion cofferdam. The original cofferdam scheme and the optimized scheme are compared from the aspects of cofferdam structure, basic parameters, implementation ideas, technical advantages and disadvantages, etc. The results show that the optimized diversion cofferdam will completely remove the clay core wall, the upstream transition layer and other ancillary structures, and change to the structure of the cofferdam upstream geomembrane anti-seepage, greatly simplifying the construction process and enhancing the anti-seepage effect.
