Abstract
In order to treat efficiently with the soft multi-layers in the middle of ground, the improved cement-soil double mixed pile is developed and the pile diameter is enlarged in the soft soil layer depth to form the cement-soil mixed column with bearing load plate. The installation mechanism, deep mixing machine, and pile installation procedure of the soil-cement mixed pile with bearing plate is presented. The field test results show that the cement-soil mixing pile with bearing load plate construction technology can ensure the cement mix content and mixing uniformity. The pile strength is greatly higher than conventional cement-soil pile, so it can be used to improved soft multi-layered ground economically and effectively, and it has a good potential application for practice.
