| Abstract: | Drainage bottom outlet is a key position in the barrage construction of Lechangxia. The suspended height of bracket in the upstream and downstream is above 11m. Bailey bracket is selected to be the bearing platform and operation platform for the construction. The water inlet section is arc-shaped for the higher requirements of appearance. In order to obtain better construction, it is necessary to adopt heteromorphic custom-made sheet steel form to ensure appearance of drainage bottom outlet, to conduct reasonable concreted hierarchical construction, to optimize construction structure and ensure pouring quality of concrete. |
