  • Patent number: 8167515
    Abstract: The hot-rolled straight-web steel sheet pile comprises a straight web delimited on each longitudinal side respectively by an interlock strip. The web has a rolled-in taper which is designed in such a way that, in a tensile test of two samples from this sheet pile which are connected by means of their interlock strips, the web is deformed plastically in the region of this taper before a failure of the interlock connection can occur. The rolling of such a sheet pile, which is distinguished in cellular cofferdams by a high plastic deformation capacity, can take place by means of slightly modified standard rolls and consequently requires no major investment.

  • Publication number: 20030053869
    Abstract: A method for driving a sheet pile (10) into the ground comprises the steps of providing a sheet pile (10) comprising at least one sheet pile interlock (14) having an interlock chamber (20); inserting an obturating device (16) into said interlock chamber (20); driving said sheet pile (10) into the ground; withdrawing said obturating device (16) from said interlock chamber (20). Important features of the method are that said obturating device (16) comprises an inflatable tube (21); that said inflatable tube (21) is inflated after said obturating device (16) has been inserted into said interlock chamber (20) and before said sheet pile (10) is driven into the ground; and that said inflatable tube (21) is again deflated before it is withdrawn from interlock chamber (20).

  • Patent number: 6443664
    Abstract: A metal sheet pile comprises a cold formed wall section to the longitudinally extending side edges of which are secured hot formed clutch sections (12). The clutch sections (12) may be produced by hot rolling, extrusion or other hot forming process and are preferably welded to the side edges of the pan or web by, for example, laser, submerged arc or resistance welding. Cold forming of the wall section from steel plate may be effected in a press, or by passing steel plate between or around cold bending rolls.

  • Patent number: 6427402
    Abstract: A wall system, comprising a plurality of pile members. The pile members are driven next to each other using a conventional pile driving system. An interlock system locks adjacent pile members together. A flowable hardenable material may be introduced into the pile members to reinforce the wall system. A reinforcing assembly may be inserted into the pile members to provide additional strength to the wall system.

  • Patent number: 6190093
    Abstract: A U-shaped sheet pile comprising a flat flange (10), two flat webs (12) connected to the flange (10) so as to be symmetrical with respect to a plane (8) perpendicular to the flange (10), and an interlocking element located at the end of each of the two webs (12). The sheet pile has a depth/useful width ratio greater than or equal to 0.18. The concave corners (18) defined by the two flange/web connections are significantly flattened by an extra thickness (26) of material so as to obtain a reduction in the resistance of the sheet pile to pile-driving. The extra thickness (26) is sufficient for a fictitious cylindrical surface (38), which has a radius at least equal to 75 mm and which is tangential to the planes extending the inner faces of the flange and the web (32, 34), to be completely located inside the said extra thickness (26) between its two tangential generators.

  • Patent number: 6092346
    Abstract: A method for connecting a standard sheet pile equipped with a standard locking element to the flange of a standard girder (31). First the initially flat edge (39) of the flange of the girder (31) is given an undulating profile having of a longitudinal series of bosses (40,42) cantilevered with respect to the flange of the girder (31). Next a connecting profile (30) including an inwardly flaring groove (36) is slotted onto the undulated edge so that the cantilevered bosses (40,42) can fit into said groove (36) and laterally lock the connecting section (30) on the undulated edge. The connecting section (30) being used is a hybrid profile which includes on the opposite side to the groove (36) a standard locking element (34) complementary to the standard locking element of the sheet pile. Into this locking element (34) is interlocked the standard locking element of the sheet pile to form a standard sheet pile joint therebetween.

  • Patent number: 5957625
    Abstract: The barrier is waterproof, and is used to contain contaminated groundwater within an enclosure. Steel elements are pile driven, the elements having rolled-over edge forms (5,6) which interengage. Upon interengagement, an enclosed hole (90) is created which extends from top to bottom of the piled elements. A scraper (19) on the junior element (8) cleans dirt out of the hole as the junior is driven down alongside the adjacent senior element (7). The hole may be cleaned out by inserting a hose pipe to the bottom of the hole (90) and flushing through with water. Then, a sealant is injected into the hole, using an injection tube in the hole. The interengagement of the edge forms (5,6) of the elements is such that the hole formed by the interengagement is constrained to its nominal size and shape throughout the whole height of the barrier.

  • Patent number: 5921716
    Abstract: A method and apparatus forming a subterranean barrier wall that is substantially impervious to liquids. The barrier wall and method of forming the same comprises interlocking a plurality of sheet piles. Each sheet pile has interlocking edges that form a sealed joint. The interlocking edges consist of two semi-circular portions, a first semi-circular groove and a first radial edge, and a quarter-circular part, a second radial edge. Interlocking the sheet piles by a first inner locking edge, a second interlocking edge and an outer locking edge at the interlocking edges forms a barrier wall forming a substantially moisture-impervious seal.
