Treatment of leakage under cut-off wall in port engineering

In a port engineering project,monitoring data reveal the presence of leakage channels under the cut-off wall.Grouting under the wall has been proven highly effective against the leakage.The key technical points are summarized regarding the design and construction for the leakage treatment under the cut-off wall in the project,encompassing the anti-leakage standard,determination of the sealing range,layout of grouting holes,grouting depth,grouting sections,grouting pressure,and grouting technology.Taken together,they form a set of technology for the treatment of leakage under cut-off walls.The sealing range determination based on water level observation breaks through the traditional technology,which can provide a reference for subsequent projects.
