| Abstract: | The first application of pier precasting and installing construcion technology to pier construction of Donghai Bribge in Shanghai is introbuced. Under conditions of harsh climate, the project implementation of preceasting and installing in pier construction becomes very necessay to reduce construction risks over sea. The key techniques and constuction are introduced. The construction experiences that the structure concrete of bridge over sea is proportionded and poured are summarized. |
