Seawall using screw piles

Abstract

A seawall is supported on a seabed along a coastline using a plurality of screw piles, each having a shaft and a helical flight about the shaft adjacent a bottom end of the shaft. The screw piles are penetrated into the seabed at spaced apart positions along the coastline such that each screw pile defines a lower portion embedded into the seabed and an upper portion protruding upwardly from the seabed. A plurality of modular wall panels, each formed of concrete material and having post apertures at opposing ends thereof, are each mounted onto two adjacent ones of the screw piles by inserting the upper portions of the screw piles into the post apertures at the opposing ends of the wall panel such that the wall panels are connected in series with one another along the coastline.

Description

[0001]This application claims the benefit under 35 U.S.C. 119(e) of U.S. provisional application Ser. No. 62 / 863,484, filed Jun. 19, 2019.FIELD OF THE INVENTION[0002]The present invention relates to a seawall for use along a coastline, and more particularly the present invention relates to a seawall using screw piles anchored into the seabed and modular wall panels supported on the screw piles.BACKGROUND[0003]Seawalls are commonly constructed along coastlines to impede erosion of the land by the exchange of sediment between land and sea and to protect areas of human activity from the action of tides, waves, or tsunamis. A typical seawall construction involves placement of piles into the seabed and a grade beam connected across the top ends of the piles at the sea floor. Corrugated metal sheets may be further anchored on the grade beam to extend upwardly from the sea floor and form a barrier wall which impedes the movement of water along the sea floor and thus limits the exchange of ...

AI Technical Summary

Benefits of technology

The patent is about using screw piles and modular wall panels to make seawalls. This allows for the components to be made in a factory and installed in different locations, such as remote locations where it may be hard to install a seawall. The technical effect is that it provides a flexible and efficient way to create seawalls that can be easily moved and installed in different locations.

Problems solved by technology

Corrugated metal sheets may be further anchored on the grade beam to extend upwardly from the sea floor and form a barrier wall which impedes the movement of water along the sea floor and thus limits the exchange of sediment between land and sea.

Known seawalls constructed in this manner are costly to manufacture and install due to the requirement for forms to cast a concrete beam in place on the sea floor.

Suitable equipment required for casting a concrete grade beam in place may not be able to access many remote areas that may benefit from a seawall.
