GROUTING DEVICE FOR FOUNDATION

PURPOSE:To lighten a weight of a tubular constitution body, improves the workability, and facilitates installation at a limited place, by forming the tubular constituting body for placing grout into a long size flexible hose. CONSTITUTION:A tubular constituting body 1 for placing grout, is smoothly inserted into a bored hole A together with an air feed pipe 8, an elevating wire 17, and a scale 18 to improve the workability. In this case, no particularly wide working space is required for insertion of the tubular constituting body 1, and this facilitates the installation of it at a limited place. After a packer 7 is lowered to a given position, the packer 7 is firmly adhered to the wall part of the bored hole A through expansion of an intermediate part 7b of the packer 7 with the aid of the fluid pressure of the air feed pipe 8. A grout is deposited into the tubular constituting body 1 through a supply hose 2, and is discharged into the bored hole A through a lower end 7a of the packer 7.
