Deep Mixing Columns with a Spreadable Tool
In the last ten years, soil mixing applications have shown a rapid development in Europe. They present an alternative when it is possible to use the soil as a building material. The process presented here is a new, wet, deep-mixing technology that allows the installation of soil mix columns larger than the initial drilling diameter. The mixing tool has two positions. Initially, it is kept lodged inside a casing and -- once pulled outside -- it spreads out under the action of springs. This technique is suitable to small drilling machines and allows the possibility to work in low headroom conditions such as basements, inside buildings, or under catenary systems. The variable diameter of the tool makes it possible to install columns through existing structures with minimal impact: small diameter boreholes through foundations or casings installed between railroad ties. In this paper, the tool and practical uses are explained based on a series of case studies.
