地下连续墙开洞及加固的工艺优化

Process Optimization of Opening and Reinforcement of Diaphragm Wall

以上海世博会A片区项目为例,对地下连续墙的开洞与结构加固施工工艺进行了分析,提出了整体钢套筒结合双侧粘钢加固的新方式。从工期、安全、质量等各方面对新工艺与常规的结构开洞和加固技术进行了对比。结果显示,新工艺在各方面的表现均要优于常规方案,相关研究成果可供类似项目参考。

Taking the A-zone project of Shanghai World Expo as an example,the construction technology of opening and structural reinforcement of underground diaphragm wall is analyzed,and a new method of integral steel sleeve combined with bilateral steel bonding reinforcement is proposed.The new technology is compared with the conventional structural opening and reinforcement technology from the aspects of construction period,safety and quality.The results show that the performance of the new process is better than that of the conventional scheme in all aspects,and the relevant research results can be used as a reference for similar projects.
