Sheet pile
An elongated element ( 1 ) having a cross-sectional shape permitting the element to be interlocked with adjacent elements, the element having a basic square shape with interlocking members ( 4,6,8 ) on at least three sides of the element, wherein the proportions of the element and the interlocking members are such that the elements can be interlocked in side by side and/or overlapping relationship.
1. An elongated sheet pile element having on a first pair of opposing faces a spigot and a socket adapted to accept the spigot of a further element, and on a further pair of opposing faces a spigot and a substantially flat face, whereby the distance of a first portion of the element between the spigot and the adjacent corner of the element being such that when two elements are positioned adjacent each other, the first two portions form a socket adapted to accept the spigot of a further element, and the distance of a second portion of the element between the socket and its adjacent edge is such that when the two elements are positioned abutting each other two second portions form a spigot adapted to be inserted into the socket of a further element.
2. The elongated element as defined in claim 1 , wherein each spigot has a head joined by a neck to the element in the form of a rounded dovetail, and the socket has a recess on each side of the socket that is adapted to receive the rounded dovetail of a further element, whereby adjacent elements are locked by sliding one element longitudinally of the other element with the spigot engaging the socket.
3. The elongated element as defined in claim 2 , where in the portions of the element extending from the recess to the edge of the element are such that when two elements are positioned with their respective flat sides abutting the two said portions form a spigot whereby a further element can engage its socket over the formed spigot to lock the elements together in overlapping relationship.
4. The elongated element as defined in claim 2 , wherein the portions of the element extending from the spigot to the edge of the element are such that when two elements are positioned with their flat sides aligned the two said portions form a socket whereby a further element can engage its spigot in the so formed socket to lock the elements together in overlapping relationship.
5. The elongated element as defined in claim 1 , wherein the element is hollow.
6. The elongated element as defined in claim 1 , wherein the element is formed by extruding a plastic material or recycled plastic material.
7. The elongated element as defined in claim 1 , wherein the element is constructed from a plastic material, cement, wood, metal or combinations thereof and whether reinforced or not.
8. The elongated element as defined in claim 1 , wherein longitudinal recesses or grooves are provided such that when assembled with a further element, a longitudinal hole or canal is formed into which a sealing compound or solvent can be placed.
