A Field Trial Study on Jet Grouting to Improve the Subsoil in Ho Chi Minh City, Vietnam

This study attempts to fabricate a single jet grouting system from used machines and the machines were modified by the authors. the assembled jet grouting system was fabricated to create soil cement mixing by high pressure beams at pressure up to 30 mpa of cement slurry or water plus cement slurry. the two soilcrete columns were created using the above jet grouting system at the bank of nhieu loc canal, binh thanh district, ho chi minh city, vietnam. the diameters of the soilcrete columns vary from 0.8-1.3 m at the top and larger 0.4 m at the bottom. the lengths of the columns were 12 m and 4 m for the column 1 and 2, respectively. characteristics of a soilcrete column are appreciably dictated by operating parameters of a jet grouting system.
