【Abstract】 The underwater construction techniques are adopted to mend and reinforce the inverted arched bottom plate of the Huangshagang sluice on the basis of comparison and analysis of the construction methods of soil cofferdam and steel plate cofferdam, and underwater construction. The materials for mending crevices in the bottom plate and underwater construction techniques are introduced. The underwater construction techniques for reinforcement of the inverted arched bottom plates of sluices with specially shaped thin reinforced concrete are developed for sediment laden rivers.更多还原
