Abstract

PURPOSE:To obtain a pile having great spherical footing without the needs for breaking bags by a method in which injection of a fluidizing liquid is stopped when the injecting pressure in a bag buried in the ground reaches a set pressure and restarted at a lower rate than the previous injection when a set lower limit is reached in a repeating manner until completed. CONSTITUTION:A bag 1 is attached to the lower end side of an existing pile 2 and a solidifying fluid liquid 5 is injected into the bag 1 through an injection tube 4 in the pile 2. The pile 2 is then buried in a pit 3 previously excavated and the liquid 5 is injected into the bag 1 from the tube 4. In this case, when the injection pressure reaches a set upper limit value P2, the injection is kept stopped until a set lower limit value P1. When the value P1 is reached, injection is retarted at a lower rate than the previous injection. The processes are repeated to complete the injection. Great amounts of the liquid 5 can thus be injected into the bag in a short time.
