The present invention relates to a pontoon which has excellent water and corrosion resistance and high strength, which is easy to adjust height, and which comprises: a body having a buoyancy space therein and including concrete and pieces of reinforcing fiber; a buoyancy control unit including multiple ballast tanks which control horizontal positions of the body, which are installed inside the buoyancy space and which have filling spaces therein, and a supply unit which supplies air and water to the filling spaces; and a guide bar which has a lower end in the water and which is inserted into a guide hole provided on the body, wherein the lower end guides the vertical movement of the body according to the changes of water levels,. The pontoon according to the present invention is provided to comprise concrete and pieces of reinforcing fibers, thereby improving water and corrosion resistant properties and strength; to use the buoyancy control unit to facilitate the horizontal equalization; to have excellent impact resistance compared with concrete that does not include pieces of reinforcing fiber; to prevent strength properties such as compression and flexural strength from being lowered; and to manufacture high quality concrete having reduced concrete contraction crack generated by water. |
