Waterproof sea-wall construction system - with rough stone break waters formed at sides of intended sealing core position and stepped construction providing trapezoidal cross=section

摘要

The system is for the construction of a waterproof seawall etc. on a solid seabed. Rough stone breakwater sections are first formed on the seabed on either side of the intended position of the sealing core, to create a space, in the centre of which a portion of the core is immersed. The intervening space is then filled in and a series of rough stone sections similar to the first ones are then laid on the latter, up to sea level. Successive above-water sections are then poured on top until the maximum seawall height is reached, so as to give the seawall a trapezium section.
