To provide a method for constructing an underwater structure capable of being installed even on the uneven bottom of the water, without forming a gap between the underwater structure and the bottom of the water, in the installation of the underwater structure such as an intake pool for atomic power generation.
The intake pool 1 is formed, for example, of a submerged dyke 7 which is installed in such a manner as to surround an intake 3 provided in an atomic power plant 2. The submerged dyke 7 is the underwater structure which is installed in a position lower than a sea level 5. The intake pool 1 has to supply marine water in the intake pool 1 to the intake 3 without the outflow of the marine water in the intake pool 1, even when the sea level 5 becomes lower than an upper end of the submerged dyke 7. Thus, a water shut-off portion 11 for preventing the outflow of the marine water to the outside of the intake pool 1 is provided in the lower portion of the submerged dyke 7. More specifically, the water shut-off portion 11 is used to prevent the outflow of the marine water to the outside of the intake pool 1 by filling a gap between the submerged dyke 7 and the bottom of the sea.
