Field Design of Jet Grouting Parameters on Soilcrete Columns

Abstract:

Method of jet grouting has become one of the ground improvement technologies used to address seepage concerns and to provide strength improvement of soils. The soilcrete columns can be also used to form seepage vertical cut-off walls from a series of continuous and interconnected vertical columns in deep pit. If the native soil is not completely mixed with slurry, the resulting columns will have soil inclusions which can increase the permeability of the column or fail barrier to water flow. Specifications of soilcrete columns that are achieved from the jet grouting procedures from the diameter and strength aspect depend on jet grouting parameters such as grout pressure, lifting speed, number and diameter of nozzles and c/w ratio and specifications of local soil. Different soil must use different jet grouting parameters.
