FIGS. 2 and 3 show a bulkhead 12 made of sheet pile panels where the tops of the sheet pile panels are finished off with a cap 18. The cap 18 also provides lateral support to the upper end of the wall. The cap 18 may be formed by poring concrete in place on the wall once the wall has been installed or the cap 18 may be preformed. The cap 18 may also be made of any suitable plastic or metal material. The wall support system of the present invention 10 employs connection beams 22 and an attached geogrid 34 to provide the necessary support to the wall structure. The connection beams 22 are joined to the individual sheet pile panels 32 of the wall. The connection beams 22 have connectors which mate with the connectors of the sheet pile panels 32. The geogrid 34 is able to provide support since it is buried by the fill of the wall. The load on the geogrid prevents the wall from being displaced. The geogrid replaces the tie rods and deadman anchors of the prior art. Wale beams 20 may be employed to further enhance and support the wall (see FIG. 4). They are typically secured across the front surface of the sheet pile panels 32 for additional wall support and are secured to the support system. If necessary multiple layers of beams 20 and geogrids 34 can be employed as seen in FIG. 4. FIG. 3 shows an illustrative view of the present invention 10 in use as a retaining wall. The retaining wall can be formed without a wale beam 20 (as shown) or it may be formed with a wale beam 20 to provide additional support if required.

    FIGS. 6-8 show the wall support system of the present invention 10 and how it is employed with the sheet pile panels 32 of a bulkhead 12 or retaining wall. The support system employs a connection beam 22, which is an elongated beam like member that extends the entire height of the sheet pile panels 32 on which it is deployed. The connection beam 22 has a connector portion with a female connector 24 and a male connector 26 disposed thereon. The connector portion has a central section 28 that is joined to an extension 40 or flange. The male connector 26 is secured to the central section 28 of the connector portion by a joining member 30. The female connector 24 is secured to the central section 28 by a joining member 30 or it can be secured directly to the central section 28 as seen in 6A. These connectors are aligned in the same plane and are on opposite sides of the connection beam 22. The male connector 26 engages with the female connector 24 on a sheet pile panel 32. The female connector 24 engages with the male connector 26 on a sheet pile panel 32. The connection beam 22 joins and secures together two adjacent sheet pile panels 32. The connection beam 22 provides several functions in addition to its primary function of joining together sheet pile panels 32 and providing a simple and easy manner of securing a geogrid to a bulkhead or wall structure. The connection beam 22, since it is a beam, stiffens each of the sheet pile panels 32, to which it is joined. Looking at the FIGS. 6-8, it is easy to see how the connection beam 22 will stiffen the panels 32 it joins. The connection beam 22 has an extension 40 that terminates in a profiled portion 38. The profiled portion 38 in combination with the extension 40 act as a beam to provide vertical stiffness to the connection beam 22. The connection beam 22 is shaped like a “T”. The Cross bar of the “T” has male 26 and female 24 connectors secured thereon. The vertical portion of the “T” is the extension 40 and the base portion of the “T” is the profiled portion 38. The connection beam 22 acts in the same manner as an “I” beam would. A “T” beam has a wider cross bar and has a narrower base. An “I” beam has uniform top and bottom members. As seen in FIG. 14, the profiled portion 38 may take on a variety of shapes, some of which will give the beam an almost true “T” or “I” shapes. The profiled portion 38 (which is the base of the “T”) may be thicker than the thickness of the extension 40. It is preferable that it is thicker since it will make the connection beam 22 stiffer providing the beam with a greater load bearing capacity. The individual shapes provide for varying strengths for the connection beam 22. This allows for supplying connection beams 22 to meet specific load requirements. The connection beams 22 can be made of plastic such as polyvinylchloride (PVC), copolymers or any other suitable plastic material. The beams can be made of fiber reinforced plastic with reinforcing fibers such as nylon, glass, carbon, and aramid. KEVLAR is the trade name for a popular aramid manufactured by Dupont. The connection beams 22 can also be made of metals such as steel, aluminum or any other suitable metal. The metal beams may be coated or galvanized to inhibit rust.

    The geogrid 34 is secured to the beams via a connection rod 42. The connection rod 42 is seen in FIG. 13 can be made of plastic, fiber reinforced plastic, steel or any other suitable metal. The connection rod 42 need not be made of the same material as the connection beam 22 on which it is deployed. The geogrid 34 may be fastened to the connection rod employing any suitable means including but not limited to fasteners. The fasteners may be rivets, screws, bolts, etc or any other suitable mechanism that is capable of securing the grid to the connection rod 42. In one method of installation, (not shown) the end of the geogrid 34 could be wrapped around the connection rod 42 forming a flap which is then, folded onto the body of the geogrid 34 and then the flap is secured to the body of the geogrid 34 by any suitable means including but not limited to fasteners. The flap of the geogrid 34 creates a pocket for the connection rod 42 so that the geogrid 34 is retained on the connection rod 42.

    The geogrid 34 is modular structure made of individual mats 36 secured to each other. A geogrid 34 may have a width of just one mat 36 as seen in FIGS. 9 and 10. Here two separate geogrids 34 are shown, where the geogrids 34 are laterally spaced from each other. The geogrid 34 may also be employed in a laterally continuous manner as seen in FIG. 11. Looking at FIG. 11, it is seen that individual mats 36 may be secured to each other by connection rods 42. The mats 36 may be secured to the connection rods 42 by any suitable means including but not limited to fasteners. The mats may be secured to each other directly without the use of connection rods 42. The mats may be secured directly to each other by any suitable means including but not limited to fasteners. The geogrid 34 is formed of the desired width and length by securing additional mats 36 to make the grid as long and as wide as necessary to support the wall structure. It has been contemplated that in the event that a continuous geogrid 34 is employed, a way to join connection rods 42 is desired. The ends of the connection rods 42 could be externally threaded (male threads) and an internally threaded connector with female threads at each end may be employed to secure the connection rods 42 together. Or each connection rod 42 may be threaded, where one end has external male threads and the other end has internal female threads, making the joining of connection rods 42 simple and rapid. If required, the geogrids 34 can be vertically stacked as seen in FIG. 12. Stacked geogrids 34 provide additional support to a single sheet pile panel 32 when the grids 34 are one mat 36 wide. Stacked geogrids 34 provide additional support to multiple sheet panels 32 when the geogrids 34 are continuous. It is desired that the mats 36 of the geogrid 34 be made of a plastic material that will not degrade in a buried environment. Suitable plastics would be PVC, polypropylene, polyethylene, or other polymers or copolymers. The mats 36 can be of woven construction or they can be extruded in sheet form. The extruded sheets could be solid, i.e. without holes or they could be perforated to allow drainage of the soil or fill which rests upon the sheets. It has also been considered that the mats 36 can be made of a non-woven plastic fabric. One such non-woven fabric is sold under the trade name TYVEK. These non-woven fabrics can be made of PVC, polypropylene, polyethylene, or other polymers or copolymers. The non-woven fabrics may be perforated to enhance their water permeability to provide for soil drainage as noted above.

    The through holes 48 in the extensions 40 of the connection beams 22 are typically drilled on site. They also could also be drilled prior to bringing the connection beams 22 to the installation site. These through holes 44 extend through the extension 40 of the connection beam 22 as seen in FIGS. 6 and 6A. It has also been considered that the beams 22 could be manufactured with a plurality of through holes 44 in predetermined locations in the extension 40 to eliminate the need for drilling. If the beams 22 are manufactured with a plurality of through holes 44, the beams 22 may be provided with a wider extension 40 to compensate for the loss in strength due to the plurality of through holes 44. The connection rods 42 can be held in place or provided with limited side-to-side movement by clamping members 46 secured around the circumference of the connection rods 42. The clamping member is seen in FIG. 7A. The clamping member 46 has a through hole 44 therein for receiving the connection rod 42. A threaded fastener 48 disposed in a threaded hole 50 in the clamping member 46, which is tightened to press against the connection rod 42 and secure the clamping member 46 to the connection rod 42. There would typically be two clamping members 46 on each connection rod 42, one secured adjacent each end of the rod 42. They can be positioned on the rod 42 such they are both either outside of the extensions 40 as in FIG. 7B. They could also be deployed as seen in FIG. 7C where both are interior of each extension 40. If joined connection rods 42 are employed on a continuous geogrid 34 it will be necessary to provide clamping members 46 on at least one of the connection rods 42. Additional clamping members 46 may be used if desired.

    FIG. 5 shows one possible sequence for the installation of a wall employing sheet piles panels 32 and the connection beams 22 of the present invention. In step 1, a sheet pile 32 in driven into the ground and then a connection beam 22 is joined to and slid down the sheet pile panel 32 and driven into the ground. In step 2, a second sheet pile panel 32 is joined to and slid down the connection beam 22 and driven into the ground. In step 3, a second connection beam 22 is joined to and slid down the previous sheet pile panel 32 and driven into the ground. In step 4, another sheet pile panel 32 is joined to and slid down the second connection beam 22 and driven into the ground and then holes 44 are drilled into the extensions 40 of the connection beams 22. In step 5, a connection rod 42 is inserted through the holes 44 in the connection beams 22. In step 6, a geogrid 34 of the desired length and width is secured to the connection rod 42 employing any suitable means. The wall is then back filled and the geogrid 34 is buried. The weight of the fill on the geogrid 34 provides the wall with the required support. It has been contemplated that other sequences can be employed for the installation. It is possible to begin an installation sequence by first driving a connection beam 22 into the ground. Then a sheet pile panel 32 can be installed on one side of the connection beam 22, slid down the length of the connector and then driven into the ground. A connection beam 22 can be slid down the other side of the just installed sheet pile panel 32 and then driven into the ground. This eliminates having an exposed edge of a sheet pile panel 32, which is unsupported and may be easily damaged. It is envisioned that in creating walls that the completed sections with attached geogrids be back filled prior to the completion of the entire wall.
