Abstract

PURPOSE: To facilitate the construction of the underground foundation by a method wherein a sinking frame which is equipped with a cutting edge and separable and a protecting frame are provided continuously and are lowered through excavation into the ground, while a sliding belt is let out, the sinking frame is disassembled and taken out when it reaches a required depth and then the foundation is constructed within the protecting frame.
CONSTITUTION: The sinking frame 1 equipped with a plurality of letting-out openings 2 on the circumference and the cutting edge 3 on the lower side is set up on the surface of the ground. To the sinking frame 1 is coupled a foundation concrete form 9 of the same diameter with the former, while the sliding belt 10 of a fixed width is inserted through the letting-out opening 2. The sinking frame 1 is made to sink by excavation of the inside thereof and simultaneously the sliding belt 10 is let out around the whole periphery of the sinking frame 1 and the concrete form 9. Next, the protecting frame 7 is laid on the top of another sequentially and coupled by a bolt 11 to prevent the collapse of earth and sand, while the frictional resistance of the earth and sand is reduced by the sliding belt 10 located between the outer periphery of the protecting frame 7 and the surface of the earth and sand, and thus the frame is sunk smoothly. Then the sinking frame 1 is separated for disassembly and taken out and, after that, while concrete being placed, the concrete from 9 is removed from the protecting frame 7, and concrete is further placed upward sequentially.
