Definitions

  • the present invention relates to a cover section of U-shaped cross section for a sheet-pile wall consisting of wavy panels, said cover section consisting of a prefabricated beam, which comprises at least one retaining projection.
  • sheet-pile walls For strengthening banks or forming quay walls, frequently use is made of sheet-pile walls, which are built up from wavy panels whose side edges are interconnected. The panels are often driven into the ground at an inclination, for instance of 10:1. Normally, on top of the upper end of the sheet-pile wall a steel cover or cap section of U-shaped cross section is arranged, which is connected to the sheet-pile wall in a suitable manner, for instance by welding. On the landside of the bank or the quay wall, normally a horizontally extending steel purlin is arranged at a short distance under the cover section, for the purpose of increasing the longitidunal rigidity of the sheet-pile wall. At intervals of a few meters ground anchors are arranged, which engage this steel purlin and prevent the sheet-pile wall from being pushed over into the water. A sheet-pile wall of this type which is known from practice is shown in Figure 1.
  • the U-shaped cover section is provided, at the innerside thereof, with spaced apart U-shaped profiles, which are welded to the cover section and function as retaining projections.
  • the distance between opposed legs of both U-shaped members is somewhat greater than the plate-thickness of the sheet-pile wall.
  • the space between said opposed legs is filled with adhesive in order to produce a strong connection between the sheet-pile wall and the cover section arranged on top thereof.
  • Ground anchors to take up horizontal forces are connected to the sheet-pile wall below the cover section, which connection requires openings to be cut in the sheet-pile wall and in the prolonged leg of the U-shaped profiles, present at such location.
  • the object of the invention is to obviate these drawbacks and to that effect the invention is characterized in that the beam is a prefabricated concrete beam, the at least one retaining projection is formed on the inside surface of at least one leg of the U-shaped cross section and the shape of said at least one retaining projection corresponds approximately with the wafevorm of the sheet-pile wall.
  • the length of a prefabricated concrete beam is a multiple of the wavelength of a sheet-pile wall panel, the retaining projection(s) being provided in such a manner that the axial ends of the concrete beam are located in a plane going through a wave trough of the sheet-pile wall.
  • An accurately form-closing connection between the cover section and the top end of the sheet-pile wall can be obtained by giving the cover section a shape as described in claim 10.
  • a cover section of this shape can be manufactured by the method as described in claim 12.
  • Fig. 1 shows a prior art sheet pile construction which is built up from wavy panels whose side edges are interconnected. The panels have been driven into the ground at a gradient of, for instance, 10:1.
  • the top of the sheet-pile wall 1 is covered by a steel cover section 2 of U-shaped cross section, which in some manner or other is connected with the sheet-pile wall 1.
  • a horizontally extending steel purlin 3, 4 is arranged on the landside of the sheet-pile wall, consisting of two U-shaped sections which may be connected to each other, with the bridging legs of the U-shape directed towards each other, by spacers 5 arranged at certain intervals between the U-sections 3, 4.
  • the sheet-pile wall 1 normally has a greater length than the length of the U-sections 3, 4, at the ends of the U-sections coupling plates 6 are arranged, which are suitably connected to the U-sections 3, 4 and a spacer 5 if any is interposed.
  • screw anchors 7 are arranged, which at one end comprise a screw blade 8, grout anchor or the like and whose other end is pressed against the sheet-pile wall 1 by means of a nut 11.
  • a clamping plate 9 is arranged under the nut 11, while on the rear side of the U-sections 3, 4 a washer plate 10 is provided.
  • the anchor rod 7 is secured in the ground at a suitable inclination, for instance 1:6.
  • Figs. 2-7 show a first embodiment of a cover section, consisting of a cross-sectionally U-shaped prefabricated concrete beam 12, made up of two opposite legs 21, 22 and a bridging leg 23 (see Fig. 5).
  • the length L of the concrete cover section is a multiple of the wavelength of a sheet-pile wall panel.
  • retaining projections 13 Provided on the inside surface of the leg 21, at suitable intervals, are retaining projections 13, whose shape corresponds approximately with the waveform of sheet-pile wall 1.
  • the retaining projections 13 are provided in such a manner that the end faces of the concrete beam of length L are located in a plane going through a wave trough of the sheet-pile wall 1.
  • the lateral flanks of the retaining projections 13, 16, 17 are designed to converge from the inside surface of the bridging leg 23 of the beam 12, as indicated in Fig. 4 by the broken line 24, in order to give the retaining projections 13, 16, 17 a "piloting" profile to facilitate fitting the concrete cover section on the top end of the sheet-pile wall 1.
  • the inside surface 25 of the leg 22 is also designed to slope, so as to give this leg 22 a "piloting" profile as well.
  • the recess 14, 18 is preferably provided at a slight inclination in the cover section 12, as is indicated by the direction of the centerline 20 in Fig. 6.
  • the leg 22 may optionally have a shorter length than the leg 21 of the cover section 12.
  • Fig. 7 the end face of the cover section 12 is shown.
  • Figs. 8-11 show a second embodiment of a cover section for a sheet-pile wall, as well as a method for manufacturing same.
  • the particular aspect of this cover section also referred to as sheet-pile capping piece or head beam, resides in the fact that a perfect retaining fit is obtained between the sheet-pile head beam and the top end of the sheet-pile wall.
  • Fig. 8 depicts a sheet-pile wall 31 whose separate panels are provided with edge jaws 39 for the mutual coupling thereof.
  • the relative position of these sheet-pile panels may vary as a result of tolerances which may arise during the manufacture of the panels or when they are being driven into the ground.
  • a block of foam material 33 is pressed on the top end of the sheet-pile wall 31, yielding an accurate impression of the sheet-pile wall in the foam material 33.
  • This block of foam material 33 is then placed in a formwork 34, whereafter a molding material is poured into the recess of the foam block 33 for the purpose of forming an auxiliary mold.
  • molding material for instance plaster can be used (see Fig. 9).
  • auxiliary mold 35 and the foam material 33 are then removed from the formwork 34, whereafter the auxiliary mold 35 is placed on the bottom 40 of the formwork 34 and this formwork is poured full of concrete 36 for forming the sheet-pile head beam.
  • a reinforcement can be arranged in the formwork 34, as shown in Fig. 14.
  • a sheet-pile head beam is obtained which fits perfectly onto a particular part of the sheet-pile wall 31, as shown in Fig. 11.
  • the slot 37 present therein is a perfect match for a specific part of the sheet-pile wall 31.
  • Figs. 12-14 show a third embodiment of the sheet-pile head beam 42 according to the invention.
  • a prefabricated sheet-pile head beam is manufactured, the slot 43 of which is made to widen gradually from one end of the sheet-pile head beam 42 in the direction of the other end, as shown in Fig. 13 by slot width a ... d.
  • the length of such a sheet-piling head beam 42 will have to be shorter than the lengths according to the first and second embodiments.
  • Fig. 12 shows the arrangement of such a sheet-pile head beam 42 on a sheet-pile wall 31.
  • Fig. 14 shows a cross section of a reinforced sheet-pile head beam 42 according to this third embodiment.
