Definitions

  • This invention relates to a retaining panel for preventing collapse or movement of ground, e.g. having a slope or the like, and more particularly to such a retaining panel having an arch-type construction.
  • the present inventor has previously disclosed various inventions relating to a retaining panel having an arch-type construction.
  • the inventor has already described how the arch-type construction has certain advantages, not only in tunnel construction but also for retaining panels.
  • a retaining panel in which a PC steel member b is chordally stretched across an arcuate arch portion a to give prestress force thereto, and wherein the displacement of the arch portion a due to earth pressure is prevented or reduced by the prestress force, thereby to reduce the occurrence of cracks so that such a panel can bear large earth pressure.
  • a single PC steel member extends through a plurality of panels to be integrally fixed thereto and that prestress force is given at one time and as a whole.
  • problems are encountered in such invention. For example, when the vertical positions of the panels are even a little displaced, as shown in Fig. 12, it is very difficult to provide the prestress force by extending the PC steel member through the panels.
  • similar problems are encountered when the panels are disposed on a curve.
  • the retaining panel comprises an arcuate arch portion, a horizontal wall provided inside the arch portion and a reinforcing portion chordally stretched to the arch portion at a right angle with respect to the wall.
  • a rack portion is defined by the arch portion, the wall and the reinforcing portion.
  • the reinforcing portion has a plurality of reinforcements disposed chordally to the arch portion.
  • the reinforcements bear tensile force to prevent the arch portion of the panel from displacement.
  • the rein­forcements will suffice so long as they are disposed and high degree of technique is not required.
  • the retaining panel according to the present invention comprises an arcuate arch portion having a reinforcing portion in which the reinforcements are disposed. Therefore, the following effects can be obtained:
  • reference symbol A designates a retaining panel according to the present invention and reference numeral 1 an arcuate arch portion.
  • the arch portion 1 is formed on both left and right ends with prismatic support portions 2,2 and on the inside with a horizontal bottom wall 3.
  • a reinforcing portion 4 is stretched chordally across the arch portion 1 at a right angle with respect to the bottom wall 3.
  • a rack portion 5 providing a groove-like space is formed by the arch portion 1, bottom wall 3 and reinforcing portion 4.
  • said reinforcing portion 4 are disposed a plurality of reinforcements 6 stretched chordally to the arch portion 1 and spaced horizontally from each other. Both left and right ends of the reinforcements 6 are bent in the form of a hook in the support portions 2,2 without staggering in the support portions 2,2.
  • the reinforcements 6 may be provided with end mounting nuts instead of having their ends bent.
  • reference numerals 7,8 designate drip holes. Also, a positioning member 9 a projects intermediate the left and right upper surface of the arch portion 1, and a hole 9 b is provided in the lower surface.
  • the anchor 10 comprises a steel anchor member 12 extending through a sheath 11.
  • the sheath 11 is made of synthetic resin or the like and has a plurality of large width expanded portions 13.
  • the width w of the expanded portion 13 is 3 to 10 times the height.
  • the sheath 11 is packed with grout materials.
  • This anchor 10 is embedded in a backing or infill 15 and the retaining panel A is fixed by a nut 14.
  • the backings 15 are sequentially stacked on the anchors 10 and then the anchors 10 are provided on the backings to fix the retaining panel A . Operations noted above are repeated for fixing the retaining panels (Fig. 8).
  • the rack portion 2 is packed with earth and sand to permit planting so that the external appearance is improved and the environment can be beautified.
  • the mechanical strength of the retaining panel A may be improved to prevent or minimise the occurrence of cracks.
  • the reinforcing portion 4 in which the reinforcements 6 are disposed enables the panel A to be used for a high mechanical strength and durability panel since the reinforcements 6 bear the tensile force acting on the panel A .
  • it may be used for a panel A having the beautiful external appearance.
  • Fig. 3 shows the large reinforcing portion 4 formed above and below the bottom wall 3.
  • Figs. 4 and 5 show the rack portion 5 formed on the lower end of the retaining panel A .
  • the present invention may be used for constructing a retaining wall to prevent a slope from collapse in the civil engineering field and further embodied in the production field of concrete products manufactured in factories.
