Application Analysis of High-pressure Rotary Jetting Cutoff Wall in Nianwanping Reservoir
In order to ensure water supply for reservoir area afforestation and irrigation of farmland and forestry,and to improve the impervious performance of the reservoir,the high-pressure jet grouting cut-off wall of Nianwanping Reservoir was constructed.Based on the test,the construction with three-pipe grouting was adopted.In the paper,application of high-pressure jet grouting cut-off wall construction technology,including construction procedure,specific cases treatment,quality control,and water filling for seepage detection are analyzed.It provides reference for construction quality control of high-pressure rotary jet cut-off wall.
