The present invention relates to a multipurpose dam. A main dam (3) and a sub-dam (4) are separated and installed as a double structure. A drainage (6) is installed on a lower portion of the main dam (3). A plurality of water gates (9) are formed on a lower portion of the sub-dam (4). Therefore, various impurities and sludge (16) which enter a river are discharged immediately without being settled or deposited on the bottom of the river. Consequently, water pollution, deep water pollution, generation of green algae, and loss of soil are prevented. Flooding is controlled. Purified water can be obtained. The multipurpose dam can be used for power generation as turbines (21), (23) are rotated by using falling or flowing water. |
