摘要
做为大坝基础防渗处理的关键,趾板基础灌浆技术参数的选定将直接关系到大坝基础灌浆防渗效果。由于所遇地质岩性、基础裂隙不一,需在实际灌浆施工前,选择有代表性的地段进行现场灌浆试验,通过现场灌浆试验成果分析,最终确定适合苏家河口水电站施工的技术参数及灌浆方法。文中主要就灌浆试验现场施工程序予以阐述,以便为类似项目施工提供借鉴。
As the key link of the seepage treatment of a dam foundation, the selection of the technical parameters for the toe slab foundation grouting is directly related to the anti-seepage effect of the dam foundation grouting. Due to different lithological conditions and foundation fractures, the representative area for the site grouting experiment must be selected before the actual grouting, and then the suitable technical parameters and grouting method can be finally determined through the result analysis on the experi- ment. The in situ construction procedure of the grouting experiment for the construction of Sujiahekou Hydropower Station is mainly described herein, so as to provide a reference for the similar project.
