蜀河水电站土石围堰防渗工程施工浅析

Initial analysis on anti-seepage project construction of the earth-rork cofferdam in the Shuhe hydropower station

阐述了高压喷射灌浆技术用于土石围堰防渗的工程原理、工艺流程、施工技术参数及施工质保措施,简单介绍了采取灌注砂浆孔,双液灌浆及化学灌浆等施工技术处理局部较大渗漏及围堰支护,并对工程的实例应用效果进行了评价。

The article describes the engineering principles, technological process, construction technical parameters and construction quality assurance measures of high-pressure jet grouting technology used for anti-seepage of earth-rock cofferdam. It briefly introduces the applications of such construction techniques as perfusion mortar hole, two-shot grouting and chemical grouting to deal with partial large leakage and cofferdam bracing, and evaluates the real application effects of the project as well.
