Earth retaining system such as a sheet pile wall with integral soil anchors
First Claim
1. A method for retaining soil using an open sheet pile cell structure comprising:
- installing a face wall;
installing a tail wall, wherein installing the tail wall includes coupling a first sheet and an adjacent second sheet along their corresponding side edges using a connection means, wherein the first and second sheets each has generally longitudinal first and second side faces, wherein at least one of the first and second sheets has an integral soil anchor attached to the connection means, such that the integral soil anchor contacts soil and provides resistance to soil forces; and
connecting the face wall with the tail wall,wherein at least one of the first and second sheets has an intermediate soil anchor extending a selected distance away from at least one of the first or second side faces of the sheet and integral therewith, such that the intermediate soil anchor contacts soil and provides resistance to the soil forces, and wherein the intermediate soil anchor is separate from the connection means.

Abstract
A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.

8. A method for retaining soil using an open sheet pile cell structure comprising:
-
installing a face wall; installing a tail wall, wherein installing the tail wall includes coupling a first connection means of a first sheet and a second connection means of an adjacent second sheet along their corresponding side edges, wherein at least one of the first and second sheets has an L-shaped integral soil anchor directly attached to its connection means and extending from a face of the sheet a selected distance, wherein the integral soil anchor is not used for the connection between the first sheet and the second sheet, and wherein the integral soil anchor contacts soil and provides resistance to soil forces; and connecting the face wall with the tail wall, wherein the integral soil anchor is a first protrusion, and wherein at least one of the first and second sheets has a second protrusion attached to the face of the at least one of the first and second sheets away from the first or second connection means. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for retaining soil using an open sheet pile cell structure comprising:
-
installing a first generally longitudinal sheet having a first side face and a second side face, a top and a bottom edge along the generally longitudinal direction, and a first and second side edges portion, wherein the edge portions have a first connection means for coupling the first sheet to adjacent sheets; and installing a second generally longitudinal sheet having a first side face and a second side face, a top and a bottom edge along the generally longitudinal direction, and a first and second side edges portion, wherein the edge portions have a second connection means for coupling the second sheet to the adjacent sheets, wherein at least one of the first and second longitudinal sheets has an intermediate soil anchor positioned on at least one of the first and second faces, and wherein the intermediate soil anchor contacts soil and provides resistance to soil forces; wherein the first or the second connection means include an angular integral soil anchor measuring at least three inches in width when viewed in cross-sectional view, wherein the angular integral soil anchor extends along the full side edge of the first or the second sheets, and wherein the angular integral soil anchor increases the soil resistance of the first or the second sheet in-situ by a factor of up to cosine 45°
