地下连续墙超深空口处理施工技术

Construction Technology for Extra-deep Empty Treatment in Underground Diaphragm Wall

结合工程项目的特点及常规空口处理技术中的不足,提出新颖的刚性接头墙体超深空口处理施工技术与柔性接头墙体超深空口处理施工技术,通过具体的施工及工程实践,证明上述两项施工技术具有节约成本,加快进度,减少环境污染,节约社会物质资源等优点,改变了常规空口处理的施工技术,在遇到类似工程项目时,可供借鉴与推广应用的施工技术。

The necessity of treating empty in underground diaphragm wall is introduced in this paper. Combined with the characters of the engineering projects and the shortages of conventional empty treatment techniques, the new extra-deep empty treatment techniques for both the rigid joint wall and the flexible joint wall are proposed. Through the real construction and engineering practice, these two construction techniques have proven their merits of saving cost, speeding-up, reducing environmental pollution, and saving social material resources. The conventional empty treatment techniques are changed, with the proposition of these two new treatment techniques, which can be of reference to similar projects.
