Abstract
PURPOSE: To prevent the deterioration in the function of surrounding the chemical jetting with an air jet cover by upward inclined setting of the jetting in a chemical grouting pipe used for the subsoil improvement in the excavated bottom bed.
CONSTITUTION: When the casing drilled hole is pierced, the drilled hole water is fed to a tip excavating section 4 through a guide hollow 5. Then, an excavation is performed as specified. Subsequantly, in the withdrawing process, a chemical is fed with a changeover valve 7 of the guide hollow 5 and slantly jetted up through a nozzle 11. On the other hand, an air jet from another air feed hollow 8 is also slantly injected up sorrounding the chemical jet to ensure that the chemical jet reachs the fixed diameter reducing the earth pressure to the jet due to the withdrawal of the casing 2. In this manner, the chemical is stirred with crushed soil by the air jet to form a column body with a set diameter. Furthermore, the air jet surrounding the chemical jet is slantly injected upward.
