Resumen
The system of reduction of the sub-pressure in vertical dikes of drawers by sheet piling consists of driving two lines of sheet piles into the foundations of the drawer until reaching an impervious layer of land on the seabed, so that the drawer rests on said lines, thus increasing the stability of the foundation bench of the maritime work, and also reducing the action of the sub-pressure, so that the own weight of the drawer can be reduced, with the consequent material savings and reduction of the environmental impact produced by the shelter work. The support between the sheet piles and the drawer will be made joining together with the sheet piles a horizontal board, on which a layer of neoprene will be placed on which to make the support.
