Abstract:
A portable seawall system to be secured to the ground for resisting the passage of water from a water side to a dry side of the seawall system when the system is in an installed position, the system comprising:a base bracket configured to be positioned generally flush with the ground when the bracket is in the installed position; a plurality of substantially identical wall sections each having a first face and an opposed second face, the wall sections being arranged end to end so as to define a generally continuous wall and extending generally vertically upwardly from the base bracket when the wall sections are in the installed position, each wall section comprising; a base wall subsection having a lower edge adjacent the base bracket and an upper edge spaced therefrom when the base wall subsection is in the installed position; an upper wall subsection having a lower edge that mates with the upper edge of the base wall subsection when in the installed position; a plurality of substantially identical triangular brace members each having a non-adjustable triangle shaped perimeter with a long side and a pair of short sides; a first plurality of the brace members each being disposed in the ground at intervals adjacent the base bracket such that one of the short sides of each brace member in the first plurality is generally flush with the ground and the remainder of each brace member in the first plurality extends into the ground when in the installed position; a second plurality of the brace members each being connected to one of the brace members in the first plurality such that one of the short sides of each brace member in the second plurality is connected to the short side of one of the brace members in the first plurality that is flush with the ground and the other short side of each brace member in the second plurality extends upwardly adjacent the first or second face of the wall sections when in the installed position; and a substantially water impermeable membrane having a first edge portion, an opposed second edge portion, and a central portion therebetween, the first edge portion being adjacent the base bracket and the second edge portion being captured between the upper edges of the base wall subsections and the lower edges of the upper wall subsections such that the membrane resists passage of water between the lower edge of the wall sections and the ground and further substantially seals the upper edges of the base wall subsections to the lower edges of the upper wall subsections when in the installed position.
