莲花大坝防渗帷幕施工包括右岸（长５０ｍ）岸幕，大坝帷幕总长１０７９．５０３ｍ。１１７８个固结孔的灌浆量为８０６８ｍ；７５０个帷幕孔灌浆量为１８７２４ｍ。水泥总耗约５１０ｔ。左岸与二坝帷幕衔接。灌浆后检查，大坝下游坝基无明显渗漏通道。这说明帷幕灌浆质量是比较好的，帷幕作用有效。目前，蓄水位２１１．４１ｍ，距正常高水位还差６ｍ多，帷幕效果还待进一步检验。
The anti-seepage curtain construction of Lotus Dam includes the right bank (50m long) shore curtain and the dam curtain length 1079.503m. The grouting amount of 1178 consolidated holes is 8068m; the grouting amount of 750 curtain holes is 18724m. Total cement consumption about 510t. Left bank and the second dam curtain connection. After grouting inspection, there is no obvious leakage channel at dam foundation downstream of dam. This shows that the curtain grouting quality is better, the curtain works effectively. At present, the water level 211.41m, 6m away from the normal high water level, the curtain effect needs to be further tested.
