PURPOSE:To easily obtain molded part when removing formwork by providing a separating agent for the inner surface of the formwork in advance in constructing an underwater continuous wall by using a box-shaped formwork temporarily set on the bottom under water. CONSTITUTION:A sheet 10 for separation is bonded to the inner wall of a box- shaped formwork 2 formed by assembling steel panels. The formwork 2 is settled to a given depth on the bottom ground E under water, an excavated pit 3 is formed below the formwork 2, and concrete C is placed to the pit 3 and the formwork 2. After the concrete C hardens, the formwork 2 is cleaned away by crane, etc. The molded part can thus be easily taken out of the formwork 2 since the separating material is provided for the inner wall of the formwork 2.
