Cofferdam construction technology of Jialing River Caojie navigation-power junction plant and desilting sluice project

The construction features of cofferdam filling work at upstream and downstream of Chongqing Jialing River Caojie navigation-power junction phase I project was introduced in this paper. By way of reasonable organization, cofferdam filling reached the required level which could live through the flood season smoothly within a drought period. The cofferdam filling work has short construction time, fast rising velocity, and good construction quality.
