Definitions

  • This invention relates to a structure for stabilising sloping ground. More specifically, the present invention relates to a structure constructed using precast concrete members for stabilising sloping ground.
  • a problem with this known process is that very large concrete blocks can not readily be brought to the slope, and that precast concrete blocks are used, so that the close contact between the concrete blocks and the natural ground surface is unsatisfactory.
  • frames are arranged in a crossing fashion on sloping natural ground, and a cement-containing hardenable material is charged into the frames to construct slope frames, thereby preventing the fall or collapse of the natural ground.
  • a structure for stabilising a slope which uses precast concrete members.
  • An independent structure is constructed by charging a cement-containing hardenable member into a space between precast concrete members provided on the slope.
  • four pairs of precast concrete side plates are arranged in the form of a cross such that the side plates of each pair are parallel and the height thereof is reduced gradually from the centre of the cross toward the free end.
  • a PC steel material is structural between opposed precast concrete end plates each provided between the free ends of the side plates of each pair, and is given prestress to make the entire structure integral.
  • the cement-containing hardenable material is then charged into a space between the pair of side plates, and the structure is secured to the slant natural ground with an anchor.
  • a plurality of the structures as above are arranged on the slant natural ground to prevent the fall or collapse of the natural ground.
  • the present invention can solve the above problems in the prior art and has the following pronounced effects.
  • Figs. 1 to 5 illustrate an embodiment of the present invention, and in which:
  • reference numeral 1 designates precast concrete base members having the general shape of a cube.
  • the four corners of the base member 1 at the outer periphery are provided with respective engagement notches 2.
  • Reference numeral 3 designates side plates of precast concrete. The height of these side plates reduces from one end toward their other end.
  • Reference numeral 4 designates precast concrete end plates. The opposite side edges of the end plate are formed with engagement notches 5.
  • the end plate 4 has four PC steel material insertion holes 6.
  • the base number 1, side plates 3 and end plates 4 are assembled in a factory or on-site. First, two base members 1 are disposed at a suitable vertical distance from each other, and two side plates 3 of each of four pairs are erected such that they are parallel and with their taller ends on the side of the base members 1.
  • each side plate 3 is coupled at its upper and lower corners to the engagement notches 2 of the base member 1.
  • the four pairs of side plates project in cruciform fashion from the base members 1.
  • Each end plate 4 is coupled to the free ends of the pair of side plates 3 by means of the engagement notches 5 of the end plate 4.
  • Lengths of PC steel material 7 are stretched between the opposed end plates 4, with their ends inserted through the holes 6. An end of the length of PC steel material 7 is secured to the end plate by means of a wedge or a nut 8. Before securing the lengths of PC steel material 7, prestress is given to them to make the base members 1, side plates 3 and ends plates 4 integral.
  • PC steel material 7 there may be used PC steel wires, PC (plain carbon) stranded steel wires and PC steel rods or bars.
  • shuttering 13 is disposed vertically at the centre of the base members 1, and an upper portion of an anchor 9 previously embedded in the sloping natural ground is passed through the shuttering 13. Further, a shuttering board 10, e.g. of plywood, is secured by means of bolts 11 to the tops of each pair of side plates 3.
  • a cement-containing hardenable material 12 e.g. concrete or mortar, is charged into the spaces defined by the side plates 3 and end plates 4.
  • the shuttering boards 10 are removed, and the structure A is secured on the slant natural ground by giving the anchor 9 prestress.
  • the anchor 9 there may be used a lock bolt or the like.
  • the previously embedded anchor 9 may be prestressed for securement because the prestressing of plates produces a considerable effect upon the structure.
  • the cement-containing hardenable material may be subsequently charged into the space between the plates. In this case, the stability of the concrete blocks being constructed is improved.
  • Figs. 4 and 5 show an arrangement of a plurality of structures A arranged in a crossing fashion and at a suitable interval. In this case, the ends of the cross-like structures A seem to be continuous.
  • the present invention relates to a structure for stabilising a slope, and that the structure according to the present invention can be provided on a natural slope surface or upon a pre-­arranged slope, for example in any civil engineering field. Further, the construction according to the present invention is constructed using factory-made precast concrete members and subsequently using a cement-containing hardenable material, so that it can be practised in the field of producing concrete material.
  • the present invention provides a method stabilising a slope, which method comprises the step of:
  • PC steel wires are used as said PC material, or PC steel bars are used as said PC steel material.
  • cement milk, mortar, or concrete is used as said cement-containing hardenable material.
  • a lock bolt or a slant natural ground anchor is used as said anchor.
