摘要
桃源水电站大坝过水围堰、土石副坝的防渗区域采用风化泥岩开挖料进行填筑,填筑前对分化泥岩开挖料进行碾压试验,说明在风化泥岩开挖料填筑体中进行高压旋喷灌浆可行,施工实践表明二管法高压旋喷灌浆成墙效果好,防渗效果明显,可在低水头大坝中推广应用。
The seepage control areas of overflow cofferdams and earth-rock auxiliary dams in Taoyuan Hydropower Station are filled with excavated weathered mudstone. The roller-compacted tests on excavated weathered mudstone are carried out before filling to verify the feasibility of applying high-pressure rotating jet grouting in weathered mudstone. The actual construction shows that the two-pipe high-pressure rotating jet grouting can achieve a good cut-off walL This construction technology can be used in low head dams.
