| Abstract: | In order to simplify the construetion of river diversion channels, the river bed rock retaining sills are adopted at both upstream and downstream job site during river closing period. It has effectively reduced the loss of ripraps while filling the gaps and secured a smooth river closure. Aided by the navigation, location control system and under strict organization and management. the river bed rock retaining sills had been constructed. |
