Earth retaining system such as a sheet pile wall with integral soil anchors
First Claim
1. An installed earth retaining system using sheet pile having integral retaining anchors comprising;
- a plurality of interlocking sheet pile, the sheet pile having a first edge, a second edge, an exterior face and an interior face, the first and the second edge positioned along opposite edges of the sheet pile, wherein adjacent edges of adjoining sheet pile interlock to form a wall; and
at least one retaining anchor integral to the sheet pile, wherein the sheet pile provide resistance in a direction normal to the face of the pile and the retaining anchors provide resistance in a direction less than normal to the face wherein the retaining anchor increase soil resistance of the overall system.

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.

6. A micro soil anchor system integral with a sheet pile retaining wall comprising;
-
a first portion of a soil anchor positioned at a distal end of a first sheet pile; and
a second portion of a soil anchor positioned at a distal end of a second sheet pile positioned adjacent to the first sheet pile, the second portion of the soil anchor configured to receive the first portion of the soil anchor such that the first and second portion of the soil anchor couple together and form a soil anchor integral with interlocking sheet pile. - View Dependent Claims (7)

8. A sheet pile for use in an retaining wall system comprising:
-
a sheet of rigid material for use as a soil retaining device, the sheet including a first side face and a second side face, a top edge, a bottom edge and a first and second side edges;
connection means along the first and the second side edges, the connection means coupling a first sheet to a second adjacent sheet; and
a protrusion extending from at least one of the first or second side faces of the sheet and integral therewith, wherein the protrusion extends from the first side and/or the second side a selected distance away from the face, the protrusion providing resistance to soil forces. - View Dependent Claims (9, 10, 11, 12, 13)
