PLACING METHOD OF UNDERWATER NONSEPARABLE CONCRETE IN LARGE WATER DEPTH PART AND JIG THEREFOR

摘要

PROBLEM TO BE SOLVED: To eliminate separation of underwater nonseparable concrete as much as possible in placing underwater nonseparable concrete on which the placing object area is comparatively narrow in a large water depth part. ;SOLUTION: In a placing method of underwater nonseparable concrete 20 in a large water depth part 40, the underwater nonseparable concrete 20 is carried up to a form 4 on which the placing object area is narrow and which is arranged in a prescribed position of the large water depth part 40, and the carried underwater nonseparable concrete 20 is placed in the form 4 from an upper opening 4a arranged in an upper part of the form 4. In this case, the underwater nonseparable concrete 20 is housed in a hopper 1 which has an openable-closable discharge port 1a in a bottom part and can house a fixed quantity of underwater nonseparable concrete 20, and the hopper 1 housing the underwater nonseparable concrete 20 is moved to a prescribed position, and the discharge port 1a is opened, and the underwater nonseparable concrete 20 is transferred into the form 4 from the hopper 1.;COPYRIGHT: (C)1999,JPO
