  6 and 7 show an example of the earth retaining work constructed using both the full-size and half-size blocks 1 and 2 and the connecting materials 8 and 9 described above.

  In the earth retaining work in this example, blocks 1 and 2 are arranged in a line in the longitudinal direction on a base 12 made of concrete and stacked in a staggered manner in three stages. In this case, for example, when only the full-size block 1 is used in the first and third stages, a half space of the full-size block 1 is formed at both ends of the second stage. Stack block 2 of size. At this time, the holes 3 and 4 in the blocks 1 and 2 of each step are positioned in a straight line in the vertical direction.

  Then, in the stacking of each stage, a half-size connecting material 9 is inserted into each hole 3 of the block 1 in the first stage. Next, the full-size connecting material 8 is inserted into the holes 3 and 4 of the blocks 1 and 2 in the second stage. In this state, each full-size connecting material 8 abuts on the first-stage half-size connecting material 9 and protrudes from the upper surface of each block 1 by a length of 1/2 of these, so the second-stage connecting material 8 The holes 3 and 4 of the blocks 1 and 2 are inserted into the connecting member 8 and stacked. At this time, the upper end of each connecting member 8 is positioned at a half of each of the holes 3 and 4 of the blocks 1 and 2 in the second stage. Then, by inserting a full-size connecting material 7 into each of the holes 3 and 4, half the length of each connecting material 8 protrudes from the second-stage blocks 1 and 2, and into this third-stage block 1 hole 3 is fitted and stacked. Since each of the third-stage holes 3 and 4 has a space corresponding to a half length of the full-size connecting material 8 in the same manner as the second-stage blocks 1 and 2, a half is formed in each of the holes. The size connecting material 9 is inserted. Thereby, each hole 3 of the block 1 stacked on the uppermost stage of the earth retaining work is closed on the same plane as the block 1 by the half-size connecting material 9.

  By stacking the upper and lower stages in a staggered manner as described above, the blocks 1 and 2 of each stage row are engaged in the row direction by the upper and lower stage rows via the full-size connecting member 8.

  In the construction of the above earth retaining work, in the movement of the full-size block 1, in the case of human power, put your hands into the two holes 3 and 3 and put your fingers into the notch groove 6 below the holes 3 and 3. lift. When a rope is used, the rope is taken out from the other hole 3 through the lower notch groove 6 from the two one holes 3 and wound around the block 1.

  The connecting members 8 and 9 are manually inserted, and at this time, the grooves 10 and 11 of the connecting members 8 and 9 are put on the fingers.

  Further, the blocks 1 and 2 are stacked by mutual contact of the contact surfaces 5 provided at the open end edges of the holes 3 and 4. Therefore, when the contact surfaces 5 are parallel on the upper and lower surfaces, the upper and lower rows can be stacked in parallel regardless of the flatness of other portions of the block.

  In the embodiment shown in FIGS. 6 and 7, the earth retaining work is placed on the base 12 having a flat upper surface. However, as shown by the phantom line in order to support the earth pressure behind it. Alternatively, the base 12 may be provided with a stepped portion 13 with the outside being raised, and the stepped portion 13 may be engaged with the lowermost block.

  Further, the cross-sectional shapes of the holes 3 and 4 provided in the blocks 1 and 2 and the connecting members 8 and 9 fitted therein are not limited to a circle, but may be a rectangle, a drum shape, or a triangle.

  FIGS. 8 and 9 show a modification of how the blocks 1 and 2 are stacked. FIG. 8 is a right-angle bent shape, and FIG. 9 is two rows in the first stage, and the entire earth retaining work is two rows thick. Each example is shown below.

  In Fig. 8, when the earth retaining work is stacked in a right angle fold, the tip of another full size block 1b is placed along the side of the full size block 1a at the corner, and both blocks 1a are placed on the upper side of this portion. , 1b is combined with another full size block 1c.

  As a result, the blocks 1a and 1b that are abutted against the right-angle bent portion and adjacent to each other are integrated by the other block 1c, and the right-angle bent portion is firmly coupled.

  In FIG. 9, when the full-size blocks 1 are arranged in two rows in a staggered manner in the first stage, the full-size blocks 1 are arranged in the horizontal direction in the second stage so as to be perpendicular to the first stage.

  As a result, the blocks 1 arranged side by side in the first row are joined together in adjacent rows in the second block 1. Further, each block 1 in the second stage is installed on the right angle with respect to the block 1 in the first stage, so that adjacent ones are joined together. In this case, by arranging two rows in a staggered manner on the first stage, the piles thus stacked are constructed by connecting the blocks to each other.

  In the above embodiment, an example in which the horizontal width of the full-size block 1 is twice the depth, that is, the size of two half-size blocks 2 is shown. The size may be equal to or larger than the size of the half block 2 and the hole 3 may be provided for each size of the half block 2.

  That is, the full-size block 1 in the embodiment shown in FIG. 1 is shown as an example in which the width is 1: 2 with respect to the depth, but the width is increased regardless of the depth dimension. However, the position of the hole 3 in this case is provided at the center in the width direction of the portion obtained by dividing the horizontal width by a fraction of an integer.
