长江堤防工程水泥土防渗墙施工质量控制

Construction quality control on cement-soil mixing pile cut-off walls for Yangtze River embankment engineerings

通过对深层搅拌桩防渗墙施工技术的研究 ,提出深层搅拌桩防渗墙施工质量控制和质量评定的基本方法。施工初期的生产性试验、施工过程中的工序质量控制、单元工程质量评定和成墙墙体的质量检验对于深层搅拌水泥土防渗墙施工质量尤为重要。

Through the research of construction techniques of deep mixing pile cut-off walls, the elemental methods how to control and assess their construction qualities are proposed in the paper. The key points of construction quality of mixing pile cut-off walls are the production tests in the initial construction, the process quality control in the construction, the quality assessment of unit projects and the examination of the cut-off walls.
