Abstract
PURPOSE: To check the spouting of the chemical upward the circumference of the tube by providing a cylindrical packer with the expnaded bottom covering a small hole for grouting in a multi-hole chemical grouting tube device for the subsoil improvement.
CONSTITUTION: At the boring, the inner tube 2 inside the outer tube 1 is stays at the fixed position and with small holes 3... for grouting covered by the inner pipe wall, water is fed vertically from above and injected to the tip bit. At the grouting, the inner tube 2 is turned to the lowering position to close the path toward the tip while small holes of the inner and outer tubes 1 and 2 match each other to grout the chemical into the subsoil. Here, a packer 7 made of rubber or the like with the upper portion fixed to the outer cylinder 1 by a clamp 8 and a cover plate 9 covering the lower portion thereof are mounted on the small hole 31 at the highest stage. Therefore, with the spouting of the chemical, the packer 7 is pressed against the subsoil 11 outside running over the cover plate 9, thereby checking the spouting upward the circumference of the tube.
