Abstract

Abstract The invention relates to a method and apparatus for protection against coastal erosion. The protection barrier is formed from a plurality of protection members which are secured together to form a mat of a desired configuration. Each protection member which is formed as a toroidal body, preferably from a discarded tire casing, is at least partially filled with concrete which is deposited about the circumference of the tire casing and occupies not more than one half of the interior chamber formed by the wall of the tire casing. To facilitate preparation of the protection member for use, a conical insert is provided. The tire casing is lowered down over the conical insert, moving towards the wided base of the insert until a lower bead of the casing rim frictionally contacts the wall of the insert. Concrete is then admitted onto the wall of the insert and moves by gravity into the interior chamber, partially filling it. Once the concrete is hardened, the tire casing is lifted, allowing it to be connected with other similarly formed protection members.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 170 words
A method of forming a protection barrier member, comprising the following steps: providing a vehicle tire casing having a central opening therethrough, a generally U-shaped interior chamber and a lower and upper beads facing the central opening; providing a conical insert member having a wider base, a narrower top and an inclined continuous wall extending between the base and the top; positioning the insert on a horizontal surface, so that the base rests on the horizontal surface; placing the tire casing over the insert, such that the lower bead of the rim frictionally engages the wall of the insert; forming a space between the inclined wall of the insert and the upper bead; depositing a concrete mixture on the inclined wall of the insert and allowing the mixture to flow downwardly, under gravity, into the interior chamber formed by the tire casing; at least partially filling the chamber with concrete; allowing the concrete to harden within the tire casing; and removing the tire casing from its engagement with the insert.
Claim 2
Independent Claim 170 words
A method of forming a protection barrier member, comprising the following steps: providing a vehicle tire casing having a central opening therethrough, a generally U-shaped interior chamber and a lower and upper beads facing the central opening; providing a conical insert member having a wider base, a narrower top and an inclined continuous wall extending between the base and the top; positioning the insert on a horizontal surface, so that the base rests on the horizontal surface; placing the tire casing over the insert, such that the lower bead of the rim frictionally engages the wall of the insert; forming a space between the inclined wall of the insert and the upper bead; depositing a concrete mixture on the inclined wall of the insert and allowing the mixture to flow downwardly, under gravity, into the interior chamber formed by the tire casing; at least partially filling the chamber with concrete; allowing the concrete to harden within the tire casing; and removing the tire casing from its engagement with the insert.
Claim 3
Dependent Claim 32 words
The method of claim 1, further comprising the step of providing a circular reinforcing member and securing the reinforcing member within the interior chamber a distance from walls forming the tire casing.
Claim 4
Dependent Claim 17 words
The method of claim 2, further comprising means for securing the reinforcing member within the tire casing.
Claim 5
Dependent Claim 36 words
The method of claim 3, wherein said securing means comprises an elongated screw passing through a wall of the tire casing and extending into the interior chamber for retaining the reinforcing member in its predetermined position.
Claim 6
Dependent Claim 24 words
The method of claim 1, wherein said wall of the conical insert has an angle of inclination of about between 3 to 10 degrees.
