PURPOSE:To construct a continuous wall without causing pollution under water by a method in which joint panels are driven into the bottom ground under water, PC plates are erected in the outside coupling portion to form a construction area of continuous wall, reinforcing bars are inserted into the inside coupling portion, and concrete is placed. CONSTITUTION:Joint panels 1 are driven at intervals into the bottom ground 9 under water, and PC plates 4 are erected in the outside coupling portion 2 of the joint panels 1. A grout 10 is injected into the outside coupling portion 2 to close the construction area of continuous wall and replaced with mud water, and reinforcing bars 7 are set in the inside coupling portion 3. Concrete is placed into the formwork consisting of the joint panels 1 and the PC plates 4 in the construction area. They can thus withstand internal and external side pressures, impact of tidal current, and the vibration of vibro-hammer and excavator, and strong underwater continuous wall can be constructed. |
