Benefits of technology

"The present invention provides a retaining wall for retaining an embankment or similar that includes a plurality of tyres arranged in a plurality of courses. The tyres are offset from vertical, and each other, to provide additional support. The offset can be at a batter angle ranging from 10°C to 20°C. The use of offsetted tyres allows for easier construction of the retaining wall, and the fill material can be easily infiltrated between the tyres. The fill material can include concrete or granular materials, and the use of shredded or hollow tyres can also be employed. The invention also provides a reinforcing section that can be formed from portions of the tyres or conveyor belt. Overall, the invention provides a retaining wall that is stronger and more stable, and can better withstand the load from the embankment or similar."

Problems solved by technology

Discarded tyres and conveyor belts from the automotive, mining and aviation industries represent a significant and growing environmental problem, due to difficulties with disposal, environmental breakdown and / or incineration.
However, the method of forming the front row is both complex and time consuming, requiring excessing tyre cutting, the use of rods 17, additional rods 24 and a relatively complex assembly procedure.

Embodiment Construction

[0069] A preferred embodiment of a retaining wall 10 according to the current invention for retaining an embankment 100 or similar, comprises a plurality of tyres 11 each having a cavity 12 defined therein at least partially filled with a fill material 13. (Alternatively tyres 11 can be solid tyres from forklifts, mining vehicles etc. In this latter case use of less fill material and a more stable wall can result). In the preferred embodiment, each cavity 12 is substantially filled with the fill material 13. The tyres 11 are arranged in a plurality of courses 14 adjacent to the embankment 100. Further fill material 15 substantially fills gaps between each of the tyres 11 and between the tyres 11 and the embankment 100.

[0070] The embankment 100 is typically excavated away from ground line 102 to define a wall at an angle to the vertical of approximately 10° to 20°, with the retaining wall 10 similarly having a batter angle of 10° to 20°. In the preferred embodiments depicted, the re...

Abstract

A retaining wall system (10) is defined which includes a plurality of tyres (11) arranged in a plurality of courses (14). The tyres can be offset within the wall and can be cut in various ways to advantageously improve the strength of the wall. In addition, reinforcing (25, 30, 32) formed from tyres or conveyor belts can be associated with the wall system to improve the structural stability of the wall.

Description

TECHNICAL FIELD OF THE INVENTION [0001] The present invention relates to retaining walls and methods for forming the same, more particularly, to retaining walls that utilise tyres and conveyor belts in their construction. When the term “retaining walls” is used in this specification, it includes walls used for retaining embankments, such as in civil engineering applications (eg. road construction, public works etc), but also includes breakwaters and groins, protecting walls, walls in tunnels and at piers, quays, etc. BACKGROUND OF THE INVENTION [0002] Discarded tyres and conveyor belts from the automotive, mining and aviation industries represent a significant and growing environmental problem, due to difficulties with disposal, environmental breakdown and / or incineration. [0003] Retaining walls formed from tyres are known in the art. For example, U.S. Pat. No. 5,480,255 discloses an impact absorbing barrier for highways, formed from whole tyres and half tyres, and in-filled with sa...
