Abstract

Abstract A surface device with erosion control features consisting of uniform T-shaped elements made of various materials (wood, metals, plastics, composites, fiberglass, reinforced concrete etc.) that are secured in a relative position to each other forming a coffer dam erosion containment and loadbearing surface. The securing methods of stapling the T-shaped elements to wire mesh or fabric backing (wood elements) or using connecting cabling, wire, rope, chains, rods, ties, pins, etc. with the (metal, plastic, fiberglass and concrete T-shaped elements) in addition to reinforcing and containment provides a means of prefabbing mats or modules of desired sizes for handling, storage, transportation and application. These mats can be used in highway construction for: stabilizing soils under roadbeds, as highway shoulders, ditch linings and erosion control of embankments. The invention can be used to construct secondary roads, logging roads, nature trails, bike and golf cart paths. These mats have military and emergency disaster uses to build temporary roads, landing strips, parking ramps, repair bomb damaged surfaces or for any use requiring a stable surface. The device of larger and heavier sizes (concrete versions) can be used to build up and restore beach and dune areas lost by erosion from natural phenomena and provide protection to coastal structures, buildings, breakwaters, sea walls, channels, etc. from erosion caused by tides, wave actions, and the forces of storms and hurricanes.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 126 words
A universally flexible fabricated ground stabilizing surface device for the compaction of soils so that load bearing traffic and load bearing uses can be effected and for erosion control or the like comprising: a. plurality of uniform T-shaped building elements secured together forming a continous barrier and surface, said elements being of substantially the same size and configuration, the T-shaped elements arranged in a pattern wherein, except for the periphery of the fabricated device each element has a pair of adjacent elements wherein the T-shaped horizontal portion of an element extends perpendicular to the I or longitudinal portion of the adjacent T-shaped element at the longitudinal midpoint, and means flexibility retaining the building elements in their relative position forming coffer dams for soil retention and compaction.
Claim 2
Dependent Claim 126 words
A universally flexible fabricated ground stabilizing surface device for the compaction of soils so that load bearing traffic and load bearing uses can be effected and for erosion control or the like comprising: a. plurality of uniform T-shaped building elements secured together forming a continous barrier and surface, said elements being of substantially the same size and configuration, the T-shaped elements arranged in a pattern wherein, except for the periphery of the fabricated device each element has a pair of adjacent elements wherein the T-shaped horizontal portion of an element extends perpendicular to the I or longitudinal portion of the adjacent T-shaped element at the longitudinal midpoint, and means flexibility retaining the building elements in their relative position forming coffer dams for soil retention and compaction.
Claim 3
Dependent Claim 19 words
A fabricated device as in claim 1, wherein the T-shaped elements are fabricated of uniform pieces of cut lumber.
Claim 4
Dependent Claim 21 words
A device as in claim 2, wherein the elements are treated with a preservative if the lumber is subject to rot.
Claim 5
Dependent Claim 19 words
A device as in claim 2, wherein the retaining means is a fabric material stapled to elements of lumber.
Claim 6
Dependent Claim 15 words
A device as in claim 2, wherein the retaining means is wire mesh or fencing.
Claim 7
Dependent Claim 20 words
A fabricated device as in claim 1, wherein the T-shaped elements are fabricated of plastics, fiberglass, or compsites of both.
Claim 8
Dependent Claim 30 words
A fabricated device as in claim 1, wherein the T shaped elements are fabricated of metal cast, extruded, or of two tubing sections welded at mid point of one section.
Claim 9
Dependent Claim 17 words
A fabricated device as in claim 1, where in the T-shaped elements are fabricated of reinforced concrete.
Claim 10
Dependent Claim 15 words
A device as in claim 6, wherein the retaining means are cables, wire or rope.
Claim 11
Dependent Claim 15 words
A device as in claim 7, wherein the retaining means are cables, wire or rods.
Claim 12
Dependent Claim 24 words
A device as in claim 8, wherein the T-shaped elements have connecting eyelets and holes to allow lifting and retention by cables or chains.
Claim 13
Dependent Claim 22 words
A device as in claim 8, wherein attachment devices are built into the T-shaped elements and are connected by pins, bolts etc.
Claim 14
Dependent Claim 25 words
A fabricated device as in claim 6, wherein the T-shaped elements of plastics or fiberglass become forms for the fabrication of T-shaped elements of concrete.
Claim 15
Dependent Claim 26 words
A fabricated device as in claim 1, wherein the T-shaped elements can be of various sizes, lengths, widths, depths, depending on the uses of the device.
Claim 16
Dependent Claim 35 words
A fabricated device as in claim 1, wherein the coffer dams formed by the placement of T-shaped elements can be filled with loose materials sand, soil, gravel, rock, etc. to afford compaction and additional stabilization.
Claim 17
Dependent Claim 51 words
A fabricated device as in claim 1, wherein the cofferdams formed by the T-shaped elements can be filled with highway bituminous asphalt and or asphalt rubber mixes that are techniques for using ground up wornout tires with liquid asphalt or other binders in place of gravel and sand in highway construction.
