Abstract

PURPOSE:To simplify the operations as well as to save power by a method in which a flexible hose for placing concrete is raised as the placing operation of underwater concrete advances. CONSTITUTION:A crane 1 is set on a caisson 11 settled on the seabed at deep water depth, and a winding drum 5 to wind up or down a flexible hose 3 for placing concrete is set on a base 2 hung down from the winding wire 4 of the crane 1. The hose 3 is lowered to a placing position and underwater concrete is placed. The hose 3 is then raised and while moving the placing position upwards underwater concrete is continuously placed. Underwater concrete can thus be placed without discontinuation of the operations and with high efficiency.
