Chat Onlineauger located at the end of the drilling tool (Kelly bar). Jet grouting can be considered a type of soil mixing which utilizes high pressure 28 to 42 MPa (4 000 to 6 000 psi) jets to hydraulically shear the soil and blend a cement grout to form a soil-cement column. ` Figure 1. Wet Deep Mixing Methods DSM SSM and Jet Grouting . Applications
Chat Online• The diameter of the formed grout columns depends on the nature of the soil and is determined by the diameter of the nozzles and the drilling parameters. • Standard grout column diameters from 300 up to > 1.000 mm • By arranging the grout columns either a secant grout column wall or an impervious jet grout bottom slab or plug is realized
Chat OnlineJet grout columns are installed by initially drilling a small hole typically 100 mm in diameter to the required depth.
