Abstract

PURPOSE: To construct the earth anchor having sufficient supporting power without widening a hole, by inserting a tension member into a pipe inserted in a prearranged depth, and forming a spherical injected mass around the tension member through operation of an pressure-injection device after filling an injection material into the pipe.
CONSTITUTION: After driving a boring pipe 1 into the ground 3 in a prearranged depth, or inserting it after boring, the tension member 2 is inserted from the upper end of the pipe 1. Next, a pressure-injection device A is installed on the upper end of the pipe 1 through the intermediary of an installation screw. Following this step, a valve 18 is opened to fill the pipe 1 fully with the injection material 4 such as mortar of high concentration or concrete contained in a hopper 19. Then, after pulling the pipe 1 upward a required stroke, the valve 18 is closed and a piston 9 is pushed downward through the operation of a hydraulic unit 20. This action triggers the squeezing out of the injection material 4 contained in the pipe 1 through a bottom 1 to form a swollen concrete mass 22 under the ground. Next, the pipe 1 is pulled out on the ground, resulting in the formation of an anchor stem body 21 having a mass 22 around the tension member 2.
