Abstract
A sheet piling for mandrel-installed engagement with an identical adjacent sheet piling. The mandrel has a guide hook and a rotating toe protector. The sheet piling has a female interlocking feature with a pair of hooks and an engagement hook for releasably engaging the mandrel guide hook. The sheet piling also has a male interlocking feature with a pair of hooks configured to engage the pair of female hooks of an adjacent sheet piling in a multi-piling wall structure.
Claims24
A sheet piling installation system for installation into a substrate, the system comprising:
- an installation mandrel comprising a substantially rigid elongate member having a top end, a toe end and first and second sides, the first side of the installation mandrel comprising an alignment hook extending longitudinally along at least a portion of its length, and the second side comprising a substantially enclosed channel extending longitudinally along at least a portion of its length, and further comprising a toe plate pivotally mounted at the toe end for movement between a first position covering the toe end of the channel and a second position not covering the toe end of the channel;
- and
- a sheet piling comprising a top end, a bottom end for driving into the substrate, leading and trailing sides, and a body configured to releasably mount onto the installation mandrel, the leading side of the sheet piling comprising an alignment flange for longitudinal sliding engagement with the installation mandrel alignment hook, a first coupling profile configured to be received within and slide longitudinally through the substantially enclosed channel of the installation mandrel, and the trailing side of the sheet piling comprising a second coupling profile.
A sheet piling comprising:
- a body defining a top end, a toe end, a leading side and a trailing side;
- and
- a mandrel-alignment flange and a first coupling profile extending longitudinally along at least a portion of the leading side, and a second coupling profile extending longitudinally along at least a portion of the trailing side.
A corner coupling for connecting a first sheet piling with a second sheet piling at an offset angle, the corner coupling comprising a first corner coupling profile for engagement with the first sheet piling member and a second corner coupling profile for engagement with the second sheet piling member.
An installation method for sheet pilings, comprising:
- mounting a first sheet piling to a mandrel;
- driving the first sheet piling into a substrate;
- removing the mandrel from the substrate leaving the sheet piling in place within the substrate;
- mounting a second sheet piling to the mandrel;
- engaging an alignment hook of the mandrel with an alignment flange of the first sheet piling;
- engaging a trailing edge coupling profile of the second sheet piling with a leading edge coupling profile of the first sheet piling;
- and
- driving the second sheet piling into the substrate with the trailing edge coupling profile of the second sheet piling remaining engaged with the leading edge coupling profile of the first sheet piling.
A reversible corner coupling for installation of a subsequently installed sheet piling member at an offset angle relative to an adjacent previously installed sheet piling member, the previously installed sheet piling comprising a leading edge with a pair of coupling hooks and the subsequently installed sheet piling comprising a trailing edge with a pair of coupling hooks, the reversible corner coupling comprising:
- a first coupling profile comprising a pair of first coupling hooks;
- a second coupling profile comprising a pair of second coupling hooks, the first coupling profile is oriented at an offset angle with respect to the second coupling profile;
- wherein the first and second pair of coupling hooks are interengagable with the previously installed sheet piling leading edge coupling hooks and the subsequently installed sheet piling trailing edge coupling hooks.
