Abstract
A system that includes a plurality of front faces configured to be arranged end-to-end in a series. Adjacent front faces are connected together by a different X-shaped or X-wye connector that facilitates installation of reinforcement tail walls. At least one tail wall is connected to each connector. A redundant reinforcing tail wall may be constructed and attached to one of the connectors to provide alternative load path(s).
Claims15
A system comprising:
- first and second curved front faces configured to retain material, the first and second curved front faces being each configured to have a load applied thereto by the retained material;
- first, second, third, and fourth tail walls each having a first end opposite a second free end;
- a first connector configured to couple the first curved front face to the first end of the first tail wall with the second free end of the first tail wall extending into the retained material;
- a second connector configured to couple the second curved front face to the first end of the fourth tail wall with the second free end of the fourth tail wall extending into the retained material;
- and
- a third connector configured to couple the first curved front face to the first end of the third tail wall with the second free end of the third tail wall extending into the retained material, the third connector being configured to couple the second curved front face to the first end of the second tail wall with the second free end of the second tail wall extending into the retained material, the second tail wall being positioned between the first and third tail walls, and the third tail wall being positioned between the second and fourth tail walls, the second free ends of the first and third tail walls being spaced apart from one another, and the second free ends of the second and fourth tail walls being spaced apart from one another, the first and third tail walls being configured to balance an entire load applied to the first curved front face such that the second curved front face and the second and fourth tail walls are not needed to balance the load applied to the first curved front face, the second and fourth tail walls being configured to balance an entire load applied to the second curved front face such that the first curved front face and the first and third tail walls are not needed to balance the load applied to the second curved front face.
A bulkhead comprising:
- a plurality of open cells each comprising a curved front face, a first tail wall, and a second tail wall, the curved front face being configured to retain material, the first tail wall comprising a first free end, and the second tail wall comprising a second free end spaced apart from the first free end to define an opening therebetween, a first of the plurality of open cells overlapping a second of the plurality of open cells;
- a first connector coupling the first tail wall of the first open cell to the curved front face of the first open cell with the first tail wall of the first open cell extending away from the curved front face of the first open cell and into the retained material;
- a second connector coupling the second tail wall of the second open cell to the curved front face of the second open cell with the second tail wall of the second open cell extending away from the curved front face of the second open cell and into the retained material;
- and
- a third connector coupling the second tail wall of the first open cell to the curved front face of the first open cell with the second tail wall of the first open cell extending away from the curved front face of the first open cell and into the retained material, the third connector also coupling the first tail wall of the second open cell to the curved front face of the second open cell with the first tail wall of the second open cell extending away from the curved front face of the second open cell and into the retained material.
A method of repairing a bulkhead comprising a cell adjacent to a damaged section, the damaged section being connected to a first existing tail wall by a first X-wye connector having first, second, third, fourth, and fifth connectors, the first connector of the first X-wye connector being connected to the damaged section, the second connector of the first X-wye connector being connected to the first existing tail wall, the fifth connector of the first X-wye connector being connected to a first front face of the cell, the damaged section being connected to both a second existing tail wall and a second front face by a second X-wye connector, the second X-wye connector having first, second, third, fourth, and fifth connectors, the first connector of the second X-wye connector being connected to the damaged section, the second connector of the second X-wye connector being connected to the second existing tail wall, the third connector of the second X-wye connector being connected to the second front face, and the method comprising:
- installing a first reinforcing tail wall configured to balance a load applied to the damaged section by the cell adjacent to the damaged section;
- connecting the third connector of the first X-wye connector to the first reinforcing tail wall,
- installing a second reinforcing tail wall configured to balance a load applied to the damaged section by the second front face;
- and
- connecting the fourth connector of the second X-wye connector to the second reinforcing tail wall.
A sheet pile connector for use with a plurality of sheet pile sections each having an edge connector, the sheet pile connector comprising:
- a central portion;
- a first edge connector connected to the central portion, the first edge connector being configured to mate with the edge connector of a first one of the plurality of sheet pile sections;
- a second edge connector connected to the central portion, the second edge connector being configured to mate with the edge connector of a second one of the plurality of sheet pile sections;
- a third edge connector connected to the central portion, the third edge connector being configured to mate with the edge connector of a third one of the plurality of sheet pile sections;
- a fourth edge connector connected to the central portion, the fourth edge connector being configured to mate with the edge connector of a fourth one of the plurality of sheet pile sections;
- and
- a fifth edge connector connected to the central portion, the fifth edge connector being configured to mate with the edge connector of a fifth one of the plurality of sheet pile sections.
