Definitions

  • the present invention relates to sheet piles, used in the building industry and public works, for the realization of foundation, retaining and protective works, the role of which is to separate two media, generally a liquid medium from a solid medium and sometimes a gaseous medium, a liquid medium or a solid medium.
  • sheet piles for construction: curtains for the defense of the banks of canals and rivers; flood protection screens along roads and highways in flood-prone areas; quay walls in ports and along rivers; swimming pool enclosure walls; silos; containment walls of basins for the storage of gases, in particular of hydrocarbons; trench armor, during excavations; terrestrial retaining curtains; protections along the roads to prevent falling rocks.
  • the sheet piles metal, concrete or wood
  • a sealant such as a cement or a resin
  • the present invention relates more precisely to the field of metal sheet piles.
  • the latches allowing the longitudinal engagement of the sheet piles are constituted by male-female assemblies with dovetails, ball joints or hooks.
  • the maximum values of the resistance modules are, to date, 1300 cm 3 / m for cold-formed sheet piles with U-section and 2100 cm 3 / m for cold-formed sheet piles at section in S or Z.
  • the two aforementioned values are those reached for single curtains, that is to say composed exclusively of cold-formed metal sheet piles interlocked head to tail, without any reinforcement.
  • cold-formed sheet piles use for locking means hook assemblies, either directly between them, or by means of generally profiled connecting pieces and also provided with hooks of the same design.
  • hook locks have the other disadvantages of being difficult to access, first at the time of manufacturing checks, then for cleaning after a first use for their reuse : it is indeed difficult to remove by spraying water or air all the dirt or mud impurities which adhere in the rear part of the hook loops.
  • Hot-rolled sheet piles avoid the last drawbacks mentioned with regard to the hooks of cold-formed sheet piles since, for their locking, they generally use male-female joints with dovetail or ball-joint sections, the tools of which are not very tormented and whose female parts, even the deepest, are easier to access for post-production checks and for cleaning.
  • the hot rolling of profiles requires six to eight passages between the rolling rolls, rolls whose failure is to wear out quickly given the stresses they undergo and the high temperatures - 950 to 1150 ° - at which they work.
  • the maximum values of the resistance moduli of hot-rolled sheet piling are 4200 cm 3 / m for the U-shaped sections and 3850 cm 3 / m for the Z-shaped sections.
  • the two aforementioned limit values are also those reached for single curtains, that is to say composed exclusively of hot-rolled metal sheet piles interlocked head to tail, without any reinforcement.
  • the present invention aims to remedy all of the drawbacks which have just been explained.
  • the sheet piles concerned by the invention are cold formed, therefore using a material whose use is more flexible than that necessary for the manufacture of hot rolled.
  • the invention proposes to lock these sheet piles longitudinally using means other than hooks, which makes manufacturing checks easier and cleaning with a view to their reuse easier, which saves money. significant energy, and also and above all what avoids the loss of material, a few millimeters wide, along the two longitudinal edges of the sheet piles.
  • the sheet piles are therefore of the type described in document FR-A-445.323, and set out in the preamble to claims 1 and 7.
  • the width of the sheet used for the manufacture of the sheet pile of the invention is equal to the developed width of the finished profiled sheet pile, and this width participates in its entirety in the calculation of the strength modulus of said sheet pile.
  • the invention makes it possible to profile sheet pile sections with a U-shaped section, with a modulus of resistance of up to 1850 cm 3 / m and existing Z-shaped sheet piles, with a modulus of up to 4100 cm 3 / m.
  • the above values are those that can be obtained by cold profiling of sheet metal 1250 mm wide and 12 mm thick.
  • the Z-section sheet piles of the invention make it possible to reach resistance modules of 23,500 cm 3 / m from sheets 20,000 mm wide and 16 mm thick.
  • the invention allows a practical response to all requests from entrepreneurs.
  • the present invention therefore has as its first object a metal sheet pile formed cold, by profiling or by bending a sheet, having over its entire length a constant section in Z comprising a central core and two lateral wings parallel and in opposite directions, said plank having, also over its entire length, two means which are complementary to each other and which extend longitudinally and continuously from one transverse end to the other of the sheet pile, each of said two means being intended to cooperate with the complementary means of a neighboring sheet pile, by longitudinal engagement, to constitute after this engagement a relatively tight continuous longitudinal latch, the first means comprising an insert covering a part of the sheet pile and the second means being formed along a of its two longitudinal ends, by a flat fold of the sheet, characterized in that its first means consists of an angle e attached to the core, near a wing, the free edge of the angle iron being turned towards said first wing, and in that its second means is formed by a flat fold of the second wing turned towards the neutral axis of the sheet pile at an angle equal to that made by the core with each of
  • the free edge of the angle of the Z sheet pile is substantially perpendicular to the wings.
  • the free edge of the angle of the Z sheet pile is substantially parallel to the core.
  • the sheet pile may include a second angle placed on the same side of the core, the free edges of the two angles being turned in opposite directions from each other, the first wing near which is brought the first angle iron then also forming a flat fold turned towards the neutral axis at an angle equal to that made by the core with each of its two wings, said fold being therefore parallel and in the direction opposite to the fold which, along the second wing , is the second plea.
  • the free edge of the attached angle iron constituting the first means is preferably spaced from the wing towards which it is turned by a distance slightly greater than the thickness of the sheet.
  • the thickness of the curtain made from sheet piles is therefore double.
  • This construction thus proves to be particularly advantageous when it is necessary to construct a sheet pile wall having very high resistance characteristics: in fact, the areas where the curtain is thickest correspond to the areas furthest from the neutral axis of the curtain which is known to be substantially located in the longitudinal median plane of said curtain located equidistant from the extreme planes formed by the wings.
  • this structure for distributing the material towards the areas of the curtain furthest from the neutral axis corresponds precisely to the ideal structure ensuring the obtaining of high resistance modules. It is therefore indeed by this construction of a sheet pile curtain with a partial overlap that the implementation of the invention ensures the production of simple curtains with very high resistance characteristics.
  • a second object of the present invention is a cold formed metal sheet pile, by profiling or by bending a sheet, having on all its length a constant section with a particular Z, U or S profile and comprising, also over its entire length, two means which are complementary to each other and which extend longitudinally and continuously from one end to the other of the sheet pile, each of said two means being intended to cooperate with the complementary means of a neighboring sheet pile, by longitudinal engagement, to constitute after this engagement a relatively tight continuous longitudinal latch, the first means comprising an insert covering a part of the sheet pile, characterized in that said first means consists of at least one quadrangular section, full or hollow, of square, rectangular or trapezoidal section, attached to the sheet pile, and in that its second means is of the same nature as said first means, the quadrangular profile of said second means being attached substantially along a longitudinal edge of the sheet pile.
  • this quadrangular section constituting the first means is supplemented with an angle whose foot is located, relatively to the base of the section, at a distance slightly greater than the width of the top of said profile and the free edge of which, facing towards said profile parallel to its top, is situated in a plane which overhangs the plane of said top with a height slightly greater than the thickness of the sheet.
  • the angle iron can then include a third wing which extends its foot and is welded to the sheet pile.
  • the quadrangular profile and the angle iron constitute a one-piece assembly which is then welded by points or by two cords flush with the two longitudinal edges of the sheet piles.
  • this locking means constituted by a quadrangular profile to a sheet pile of the section with a Z-shaped section
  • said sheet pile is then characterized in that its first and second wings form a flat fold turned towards the neutral axis of the sheet pile, in that a first quadrangular section is placed flush with the fold of the second wing, on its face facing the core, in that a second quadrangular section is placed on the facing core screw of the first profile, said first and second profiles being located at the same distance relative to the second wing, and in that a third and a fourth quadrangular profiles are placed, respectively on the fold of the first wing and on the core , on the faces which do not face each other, said third and fourth sections being located at the same distance relative to the plane of the first wing, this distance being equal to that which separates the first and second sections from the dry wing wave reduced by the width of the top of said sections.
  • This Z-shaped sheet pile construction like the previous one, allows partial overlapping of sheet piles interlocked head to tail, by their wings and part of their webs, so that high strength characteristics can also be obtained by the use of this solution.
  • the Z-shaped sheet pile may, below its first to fourth sections, comprise a plate whose foot is located, relatively to the base of the section, at a distance slightly greater than the width of the top of said section.
  • the sheet pile may include an angle whose first wing is welded to the sheet pile and whose foot of the second wing is located, relative to the base of the profile, at a distance slightly greater than the width of the top of said profile.
