<P>PROBLEM TO BE SOLVED: To provide a PC ground tank without the risk of collapse of a part to tense and fix a PC cable in a circumferential direction due to filling defect of concrete or the like by eliminating a pilaster in a conventional structure constructed integrally with a sidewall when tensing and fixing the PC cable in the circumferential direction of the PC ground tank, and its construction method. <P>SOLUTION: The PC ground tank includes at least a concrete bottom slab and a cylindrical or roughly cylindrical concrete sidewall 1, and is formed by disposing at least a PC cable 5 in the circumferential direction to the sidewall 1. Of the sidewall 1, at a sidewall level where the PC cable 5 is present, at least one or more connection parts 1A connecting two ends 5a and 5b of the PC cable are present. The connection part 1A is projected from the sidewall 1 to the outer side and has a recessed groove 1b on a part thereof, and the ends 5a and 5b of the PC cable are connected inside the recessed groove 1b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
