Abstract

PURPOSE: To prevent water from becoming muddy by providing a water bottom operation territory so that it may be covered with a covered member, and connecting a tremie and a water recovery pipe with the covered member, and then, placing a hardening-material within the operation territory through the tremie.
CONSTITUTION: A space 11 is formed by bulging the center portion of a rubber membrane 2 spread on the water bottom 10. Next, the lower end of a tremie 4 which has been taken down from a plant ship 1, is connected to the membrane 2, and also the lower end of a water recovery pipe 5 which is supported above the surface of the water by means of a floating body 9, is connected with the membrane 2 and is made to communicate with the space 11. Next, the valve 7 of the pipe 5 is closed, and also valves 6, 8 are opened, and concrete is poured into the inside of the tremie 4, and placed at the water bottom within the membrane 2. And the water within the space 11 rises up through the inside of the pipe 5, and a muddy degree sensor 12 detects the muddy degree of the water. Moreover, when the water is not muddy, the water is returned above the water surface via the valve 6, and when the sensor 12 detects muddiness, the valve 6 is closed, and also the valve 7 is opened, and the water is sent to a muddy water recovery processing means.
