Abstract
PURPOSE: To prevent the release of soil and sand to the outside of a boring pipe for preventing the occurrence of an incident, e.g., the bending of pit, etc., by interrupting the outflow of ground water by a check valve even when the boring pipe reaches below the ground water level by attaching the check valve to the boring pipe.
CONSTITUTION: A Kronen bit 17 is attached to the tip 11 of a boring pipe 10 to close the tip 11, and the boring pipe 10 is driven underground. An injection pipe 18 is inserted into the boring pipe 10, and a grout 19 is gradually injected underground while drawing out the inection pipe 18 until reaches at the surface of ground. A tension member 20 is inserted and the Kronen bit 17 is removed from the boring pipe 10, whereupon althrough an aperture is formed in the joint part between the Kronen bit 17 and the boring pipe 10 and the grout 19 is ready to be pushed to outside by the pressure of ground water, the bottom 14 of a check valve 13 prevents the outflow of the grout 19. A cap 21 is attached to the head of the boring pipe 10, and while injecting the grout 19, the boring pipe 10 is drawn out.
