PURPOSE:To reduce the cost of construction of a caisson levee by a method in which concrete, etc., is poured into a base cloth at the lower part of a caisson and the base cloth is packed into the aperture between the downside of the caisson and a rubble mound. CONSTITUTION:In a constructing method for a caisson levee, consisting of a process to form a roughly levele rubbled mound, a process to set a catamaran barge 2 with apuds on the rubble mound 1 by utilizing the spuds 5, and a process to hanging down the caisson 7 from the catamaran barge 2, concrete, etc., is packed into a base cloth provided at the downside of the caisson 7 settled to a given level from the rubble mound 1 and packed into the aperture between the downside of the caisson 7 and the rubble mound 1. By this, the rubble mound 1 is integrated with the lower end of the caisson 7 with concrete, etc., to increase the bearing force, and therefore the construction cost can be reduced. |
