摘要
介绍了铁川桥水电站大坝上游面裂缝采用"凿槽嵌缝+超细水泥灌浆+表面防渗补强"、下游面裂缝采用"凿槽嵌缝+超细水泥灌浆"的施工工艺,施工后压水试验及取芯检查的结果表明,灌浆效果显著。
The article introduces construction technology of crack treatment for Tiechuan Bridge Hydropower Dam bycaulking chisel groove, superfine cement grouting and surface anti-seepage reinforcement on upstream surface, caulkingchisel groove and superfine cement grouting on downstream surface, the result of water pressure test and core examinationafter construction shows the grouting effect is remarkable.
