Large Diameter Rapid Jet Grouting in Taipei Silty Soil
Jet grouting method has been widely used in Taipei MRT construction projects. Due to the limitation of construction space and complicated utilities layout at the shallow depth, there is a need to minimize the number of borehole drilling and maximize the diameter of grout column to facilitate the jet grouting work in urban area. Accordingly, this study discusses the Rapid Jet Grouting (RJG) method that can install a large diameter grout column at large depth. A test on RJG method is to be performed to demonstrate its applicability in urban area. The observation of the excavated RJG grout columns in deep silty sand and silty clay layers shows that the RJG method had excellent quality and could deliver the designed diameter (up to 3.5 m) of grout columns at a depth of 20 m through adequate operating parameters. Besides, the strength of bored specimens from jet grout columns can also meet the designed strength by proper control of water-cement ratio.
