As illustrated in FIG. 1, the barrier members are adjacent to and interlocked with each other so as to form a continuous barrier wall 10 as are commonly known. The barrier wall 10 may, by way of non-limiting example be a sheet piling wall wherein the barrier members comprise impermeable sheets. Barrier members 12 and 14, such as barrier piling sheets, for use in forming barrier walls in soil formation 8 are known in the art. Methods of inserting such barrier member are also known in the art, such as, by way of non-limiting example, by utilizing known pile driver methods such as drop hammers, vibratory hammers or plate tampers and excavators, utilizing a mandrel or digging a trench to receive the barrier members 12.

(22) Each barrier member comprises a body having a substantially rectangular outline defined by top 16, bottom 18, and first and second side edges, 20 and 22, respectively. As illustrated in FIG. 1, the barrier member 12 may comprise a sheet of material having front and rear surfaces, 15 and 17, respectively and a variety of cross section profiles as are commonly known in the art. For example, by way of non-limited example, as illustrated herein, the barrier member 12 may have a substantially z-shaped profile although it will be appreciated that other profiles may useful as well such as, a planar, a double z-shape, u-shaped or c-shaped cross section profile. As illustrated in FIG. 1, the top and bottom edges 16 and 18 are substantially parallel to each other. Furthermore, the first and second side edges 20 and 22 are substantially parallel to each other and substantially perpendicular to the top and bottom edges. With reference to FIG. 2, the first edge 18 has a first connector 24 disposed therealong while the second edge 22 has a second connector 26 disposed therealong. As further described below, the first and second connectors 24 and 26, are adapted to cooperate with corresponding first and second connectors of adjacent panels. The barrier members 12 may be formed of any known material in the art. Barrier members may be formed of metal, such as steel or aluminum, resins such as vinyl, polyvinyl chloride (PVC) or other known plastics, or composite materials such as fiberglass or carbon fiber by way of non-limiting example.

The apparatus further comprises a bridging plate 80 extending therebetween so as to maintain the gap 65 at a width corresponding to the thickness of the barrier members 12 and 14. The rear panel 42 extends between first and second side edges, respectively and top and bottom edges, 48 and 50, respectively. As illustrated, the rear panel 42 has a length between the side edges 44 and 46 corresponding to two barrier members 12 connected together and a profile shaped to match such two barrier panels. In particular, the rear panel is sized to span two barrier members with connection between such barrier members being located at a midpoint of the rear panel 42. The rear panel 42 has a height extending between top and bottom edges 48 and 50 selected provide support and stability to the barrier members 12 and 14 connected thereby. In practice, it has been found that a height of between 6 and 30 inches (152 and 762 mm) has been useful although it will be appreciated that other heights may be useful as well.

(25) As illustrated in greater detail in FIGS. 5, 7, and 8, the first and second side edges 44 and 46 are profiled to match the profile of the first and second side connectors 24 and 26 at those locations. As illustrated in FIGS. 7 and 8, the first and second edges 44 and 46 therefore are engaged against and form a seal with the first and second connectors 24 and 26.

(26) The apparatus 40 may include first and second front panels, 60 and 62, respectively each being sized to correspond to a single barrier member.

(27) Accordingly, as illustrated, two front panels are matched to a single rear panel to form a single apparatus for supporting two barrier panels. The first front panel 60 extends between first and second side edges, 62 and 64, respectively and top and bottom edges, 66 and 68, respectively. The second front panel 70 extends between first and second side edges, 72 and 64, respectively and top and bottom edges, 76 and 78, respectively. As illustrated, each front panel 60 and 70 has a length between the side edges corresponding to a single barrier member and a profile shaped to match such single barrier panels. Each front panel 60 and 70 has a height extending between top and bottom edges 66 and 68 and 76 and 78 selected to provide support and stability to the barrier members 12 and 14 connected thereby. In practice, it has been found that a height of between 6 and 30 inches (152 and 762 mm) has been useful although it will be appreciated that other heights may be useful as well.

(28) As illustrated in greater detail in FIGS. 5, 7 and 8, the first and second side edges 62, 64, 72 and 74 are profiled to match the profile of the first and second connectors 24 and 26 at those locations. As illustrated in FIGS. 7 and 8, the first and second side edges 62, 64, 72 and 74 therefore are 20 engaged against and form a seal with the first and second connectors 24 and 26. Additionally, the first and second front panels 60 and 70 have a gap generally indicated at 79 between the second edge 64 of the first front panel 60 and the first edge 72 of the second front panel 70.

(29) The bridging plate 80 comprises a profiled planar member having an outline corresponding to the gap 65 extending between first and second edges, 82 and 84, respectively. As illustrated, the bridging plate 80 has a length corresponding to two barrier members in common with the rear panel 42 and may include at least one platform 86, 88 and 89 at a location corresponding to a connection between the first and second connectors 24 and 26. The bridging plate 80 may be welded or otherwise adhered to the front and rear panels 60, 70 and 80 so as to form a unitary body therewith. Optionally, the birding plate 80 and front and rear panels may be co-formed as a single body through casting or the like. With reference to FIG. 7, a central platform 88 may be sized and located to receive both connectors 24 and 26 thereon so as to assist with sealing a connection between the first and second connectors 24. Furthermore, as illustrated in FIG. 8, an end connector 86 may also be sized and located to receive both connectors 24 and 26 thereon so as to assist with sealing a connection between the first and second connectors 24. As illustrated in FIG. 8, the end 62 of the front plate 60 will overlap the connector and adjacent plate by an amount sufficient to engage against the front surface of the barrier member and form a seal therewith.

(30) In operation, as illustrated in FIG. 2, a first pair of barrier members 14 may be located within a soil formation and an apparatus 40 thereafter located upon the top edge 16 thereof. As illustrated in FIG. 3, thereafter, a second pair of barrier members 14 may then be located upon the apparatus with the bottom edge 18 located within the gap 65 to form a connection between as illustrated in FIG. 6. As illustrated in FIG. 1, the apparatuses 40 may be vertically staggered relative to each other to provide additional strength to the overall barrier wall.

(31) In an embodiment, the device connects sheet panel of non-fusible material together, creating a structural and permeable connection. The use is for applications that require a greater length than can be shipped or manufactured.

(32) In an embodiment, the device has component, such as a plate, made of a strong, noncorrosive material and may be bonded with other material to create a permeable barrier, such as stainless steel. In an embodiment, the component may be formed in any shape that is corrosion resistant and has strong structural properties as well. In an embodiment the center web's height and thickness may be the same or different. In an embodiment, the side plates or flange is slotted and welded together by any weld known in the art, such as a plug or spot weld. In an embodiment, on the interlock connections the web baseplate may be extended to eliminate any difference in thickness or miss alignment of the interlock connection. The center web gives the sheet lineal structure, creates a pocket for sealant, and covers and seals holes in the sheet that may be used for lifting. In an embodiment, the center web's shape may be identical to the sheet panel's shape including, or alternatively not including, the interlock connection. This would create an exact displacement from the lower sheet to the upper sheet. The sealant may be applied prior to assembly. During assembly, the sheet panels may be offset. The sealant cures and prevents any movement, and creates a permeable barrier from one side of the wall to the other.
