随着我国大跨桥梁建设的发展,桥梁锚碇基础的地下连续墙施工技术要求日益突出。结合广州珠江黄埔大桥南、北锚碇的嵌岩地下连续墙施工,针对不同的工程地质条件,着重介绍了槽段划分、导墙和施工平台、泥浆系统、成槽工艺等关键施工工艺。经实践证明,采用这些施工工艺,取得了很好的经济效益和社会效益。
With the development of China’s large-span bridge construction, the technical requirements for the construction of underground diaphragm walls based on anchorage of the bridge have become increasingly prominent. According to the different engineering geological conditions, the key construction technologies such as trough section, guide wall and construction platform, mud system and slot forming process are introduced emphatically according to the construction of embedded rock continuous diaphragm wall of the south and north anchorage of the Pearl River Huangpu Bridge in Guangzhou. Practice has proved that the use of these construction techniques, made a very good economic and social benefits.
