Definitions

  • the invention relates to a sheet pile with provided at their longitudinal edges halves of a Larssensches, which is positively connected with similar sheet piles to a sheet pile wall, wherein the lock half has a lock chamber and the other half lock has a matching lock head.
  • Sheet piles which are positively connected via similar provided on their longitudinal edges locks with similar sheet piles to a sheet pile wall, have long been known. Spall planks with larssen locks have proven particularly useful. It's been around for around 100 years. Such sheet piles are used in hydraulic engineering and civil engineering to limit and reinforce embankments. But also in building such sheet piles are used, for example as an outer shell of buttresses.
  • the invention has for its object to provide a sheet pile, which can be both easily rammed into the ground, as well as in connection with adjacent sheet piles to a sheet pile wall ensures a permanent connection through her castle.
  • the sheet pile according to the invention is characterized by a variety of advantages due to the simple and material-saving measure of the outside material accumulation. So it has a higher resistance moment and an increased buckling stiffness. When driving into the ground, it is characterized by a high torsional rigidity. These properties also have a positive effect on the insertion of the lock head into the lock chamber.
  • the measure according to the invention results in an increase in the breaking strength of the lock, namely the lock chamber, and allows higher forces perpendicular to the sheet pile wall plane and to the longitudinal axis of the lock transfer. Also for the material flow during rolling, the flattening has a favorable effect. Finally, despite the external material accumulation, which leads to an increase in the cross section of the sheet pile, the forces required for the ramming reduced.
  • the outer contour of the flattened transition region merges tangentially into the leg of the sheet pile profile and the adjacent corner region of the lock chamber.
  • the central portion of the transition region may be slightly concave to even.
  • the flute-forming, angled transitional area of the projection and subsequent leg of the sheet pile profile can be flattened by material accumulation on the outside.
  • the outer contour of the flattened transition region in the outer groove of the approach tangentially in the leg of the sheet pile profile and in the free end of the approach over.
  • the free leg of the lock chamber is reinforced by an external material accumulation to form a corner.
  • Figure 2 shows an enlarged section of the Larssentsches the sheet pile wall of Figure 1 in axial plan view
  • the sheet piling consists of several similar hot-rolled sheet piles 1,2,3, each having a Z-shaped sheet pile profile.
  • Other sheet pile profiles such as U-profiles, however, are conceivable.
  • Characteristic of such sheet piles is that at the edges of the actual sheet pile profile consisting of legs 1a, 1b, 2a, 3a and flanges 1c, the halves of a lock, e.g. so-called Larssenschlösser 4,5, are formed, which engage positively in the installed state.
  • the lock half 7 of the adjacent sheet pile 3 has a substantially in Cross-section triangular lock head 7a, which sits in a substantially positive fit in the lock chamber 6a.
  • this groove 6c is flattened by an accumulation of material 6e.
  • the outer contour 6f of this flattened transition region merges tangentially at both edges into the outer contour of the web 1b or the adjacent corner of the lock half 6, where transition radii 6g, 6h are formed.
  • the outer contour 6f of the central portion of the transition region may be flat or formed as a weak groove.
  • the thus reinforced region of the groove 6c is supported with its outer contour 6f opposite flat side 6h on a correspondingly flat side trained 7b of the lock head 7a.
  • an improved positive engagement is also realized in that the free leg 6i of a lock half 6 is reinforced by an accumulation of material 6k to form a corner.
  • the free leg 6i acts on the leg 3a of the adjacent sheet pile 3 arranged strip-shaped projection 7c together.
  • this second lock half 7 is reinforced according to the first half of the lock 6.
  • an existing between the neck 7c and the adjacent leg groove 7d is flattened by an accumulation of material 7f.
  • Its outer contour 7g merges tangentially at its two edges into the outer contour of the web 3a and the free end of the neck 7e, where transition radii 7i, 7h are formed.
  • the middle portion of the flattened transition region may be flat or slightly concave.

Abstract

L'invention concerne une palplanche (1) comportant des moitiés (6, 7) de serrure de type Larssen (4, 5), prévues au niveau de ses grands côtés. Ladite palplanche peut être assemblée par liaison de forme à des palplanches similaires, pour former un rideau de palplanches. Il est prévu, pour renforcer la résistance au flambage et au gauchissement et pour améliorer l'aptitude à l'accouplement à crabot de la serrure, y compris en contrainte de traction, que la zone de transition entre la chambre de serrure (6a) et la branche (1b) adjacente du profilé de palplanche, ladite zone de transition étant coudée et formant une gorge (6c), soit aplatie par une agglomération de matériau (6e) côté extérieur.
