Abstract
PURPOSE: To make highly-reliable underwaters concrete casting by a process wherein a tremie pipe having a switching valve in the vicinity of the lower end is placed underwaters and concrete is thrown onto a plunger slidably fitted in the pipe down underwaters with the opening of the switching valve adjusted.
CONSTITUTION: A tremie pipe 1 having a switch valve 2 about 1m upward for example of the lower end is placed underwaters with the valve 2 opened. Next, the valve 2 is closed, water level 3' is raised above that outside by supplying water to the pipe 1, a plunger 4 is slidably fitted in the pipe 1, and concrete 5 is thrown in. Next, the water level in the pipe is lowered by gradually opening the valve 2 so that concrete drops by the balance between the weight thereof and water pressure. When having reached the valve 2, the plunger 4 is pushed out from the lower end of the pipe 1 with the valve 2 fully opened, and concrete is cast underwaters through the pipe 1. The valve 2 can be closed when concrete casting is interrupted on accident for example.
