Abstract

Abstract: Freezing method sinking is special construction method to reinforce the unstable alluvial layer and the loose water-bearing rocks by freezing the groundwater temporarily using artificial refrigeration technology. With the development of deep coal resources in east China coalfield, the application of high strength and performance concrete technology in deep alluvium freezing method sinking engineering is urgent. Therefore, the technical difficulties of high strength and performance concrete technology in deep alluvium freezing method sinking engineering are summarized. The research process of high strength and performance concrete are also reviewed. China building materials academy have obtained remarkable achievements in the research and application of high strength and performance concrete technology in deep alluvium freezing method sinking engineering. Complete set of technology and process has been developed. The relevant technology and process has been used well in multiple demonstration projects, such as ZHAOGU west wind well. These achievements provide the technical support for the design and application of high strength and performance concrete in the deep alluvium sidewall, having a good application promotion value.
