  • the recession is accomplished by causing the lower ends of the connection pins protruded from the lower contracted portions (h2) of the connection pin insertion holes (h) of the upper block units (U2) to contact the upper expanded portion (hi) of the connection pin insertion holes (h) of the lower block units (Ul).

  • the tapered portions (h3) of the connection pin insertion holes (h) facilitate the insertion of the connection pins (P) into the connection pin insertion holes (h), catch the head portions of the connection pins (P) to prevent the connection pins (P) from being separated from the connection pin insertion holes (h), decrease the transverse movement of the upper and lower block units to prevent the earth wall from being pushed or moved forwards, and increase the lateral movement of the upper and lower block units to have high resistance to uneven settlement.

  • the reason for the extension of the external force absorption grooves 61a and 63a and the addition of the external force absorption grooves 64a at the corners of the block is to prevent the displacement of the earth wall constructed using the blocks and improve the resistance of the earth wall to uneven settlement, and its detailed description will be given later.

  • FIG. 47 is a perspective view illustrating a state in which an earth wall is constructed using geogrid reinforcing members.
  • the blocks are supported by the geogrid reinforcing members 80 by latching the front ends of the geogrid reinforcing members 80 onto the connection pins (not shown) inserted between the upper and lower block units (Ul and U2).
  • FIG. 48 is a front perspective view of the earth wall constructed using the above blocks, on which vegetation is grown.

  • the curved earth wall as shown in FIG. 49 is constructed using the blocks of FIG.
  • the vertical ribs 66 formed at both sides of the lower block units contact the vertical ribs 66 formed at both sides of the upper block units, and the remaining parts of the lower block units are not interfered with the remaining parts of the upper block units by the extension of the external force absorption grooves 61a and 63a and the addition of the external force absorption grooves 64a.
  • connection pins (P) the range of the transverse movement of the connection pins (P) between the upper and lower block units (Ul and U2) is increased, thereby increasing the gradient of an earth wall constructed using the above blocks. Further, the range of the lateral movement of the connection pins (P) is not lower than that of the block of the earlier embodiment of FIG. 40.
  • the present invention provides a large-sized block having a large width, which rapidly constructs a plantable reinforced earth wall using equipment to eliminate worker's physical burden, a plantable reinforced earth wall constructed using the blocks, and a method for constructing the earth wall using the blocks.

  • the front surface of the vertically constructed earth wall is afforested. As occasion demands, the soil filling portions are not filled with soil.
  • block units obtained by vertically stacking a plurality of blocks are vertically stacked crosswise, thereby preventing the lower portion of an earth wall constructed using the blocks from being damaged by shearing force applied due to load of the blocks.
  • the blocks have external force absorption grooves having a shape effectively absorbing the horizontal displacement of the blocks when the ground is unevenly settled, thereby preventing the breakage of horn-shaped portions and central portions of the blocks by shearing force. Further, the connection between upper and lower blocks and between blocks and reinforcing members is improved, thus preventing the movement and the protrusion of the blocks and minimizing the generation of defects of the earth wall after construction.

Abstract

L'invention porte sur un bloc de grande taille permettant de construire rapidement un mur de terre plantable renforcé, en éliminant les travaux physiques durs, comportant une partie remplissable de terre (60) et des plans en retrait (12, 12') situés de part et d'autre de la surface frontale (10) du bloc ce qui permet d'exposer partiellement la partie remplissable de terre (60) à la surface frontale du mur de terre, et aux plantes de pousser sur la partie frontale du mur et empêche les fissures dues au déplacement horizontal des blocs lorsque le sol n'est pas tassé uniformément. L'invention porte également sur un mur construit à l'aide desdits blocs, et sur le procédé de construction dudit mur par empilement vertical transversal des blocs de manière à ce que la partie inférieure du mur ne soit pas endommagée par les forces de cisaillement résultant de la charge des blocs.
