When forming a revetment surface by laying a large number along the side, if only the general-purpose block 20 is laid, a half end is generated at the end of the desired revetment surface, that is, the above-mentioned position located at the end of the length and extension direction. The vertical side portion 22 and the horizontal side portion 23 are shaped like a ridge, and the edge portion of the revetment surface is continuously formed in a staircase shape, so that the edge portion cannot be finished linearly. The part revetment block 1 is laid alone or together with the adjustment revetment block 10, and the laying method will be specifically described below.

  For example, FIG. 6 shows a case where a half end is generated at the left end portion (end portion of the slope extending direction) of a desired revetment surface. First, the end revetment block 1 laid on the half end portion is, for example, shown in the above figure. A block group suitable for the half end portion is selected from a plurality of types of block groups having different inclination angles α of the inclined side portions 4 shown in FIG. 1 to FIG. 3 (in this case, the end portion revetment block 1 shown in FIG. 1 is selected). Next, when the selected edge revetment block 1 is laid in such a manner that the inclined side portion 4 is continuously arranged so as to form the edge portion of the revetment surface, the edge adjacent to the vertical direction (slope length direction). Arrangement direction (in this case, left-right direction) so that the inclined side portion 4 of the revetment block 1 for the section is along a straight diagonal line extending in the up-down direction with a predetermined inclination angle α with the left-right direction (slope extension direction) For example, the adjustment revetment block 10 appropriately selected from the adjustment revetment block group shown in FIGS. 5 (a) to 5 (e) is used alone (for example, the bottom of FIG. 6). 2nd, 5th and 6th stage) or in parallel (3rd and 4th stage from the bottom in FIG. 6), which is interposed at the end of the row where the half ends occur, and where the length of the half ends is not necessary to be adjusted Without the revetment block 10 for adjustment (the maximum in FIG. 6). Stage), by laying the bank protection for end block 1 to the column end the odd occurs substantially satisfy the odd part.

The inclination angle α between the edge portion of the surface and the arrangement direction is determined. The inclination angle α with respect to the arrangement direction is, for example, shown in FIGS. 2 (B) and 2 (D) ((C) and (E)). Select the other end revetment block 1 in which the lengths of the parallel connecting side portions 5 connected to the base side portion 3 of the block body 2 as shown in FIG. 1 are different from those shown in FIG. Similarly, it can be appropriately changed by laying continuously.

  In addition, in FIG. 6 to FIG. 9, one type of end revetment block 1 that matches the half end portion generated at the end portion of the desired revetment surface is selected and formed by the inclined side portion 4 of the block main body 2. Lay the revetment blocks 1 for each end to make the edge of the revetment surface a straight diagonal straight line extending in the vertical direction (slope length direction) or in the left-right direction (extension direction of the slope) However, a plurality of types of end revetment blocks 1 suitable for each half end are selected, and as shown in FIG. 10, each end revetment block 1 is inclined as described above. The side 4 is laid so as to form the edge of the revetment surface, and the inclined side 4 of the adjacent end revetment block 1 is continuous, and the inclination angle is different and follows a normal line that bends differently.

Are provided on the lower side of the side wall so as to be interspersed with adjacent convex portions 24 adjacent to the corners of the substantially pentagon, and are substantially perpendicular to the base portion 3, the base portion 3 and the connecting side portions. A connecting rebar 25 is provided in a protruding manner on the side wall of the connecting portion 5.
Further, adjustment revetment block 10 shown in FIG. 14, the vertical of the view 11 to maintain the substantially same structure as the general-purpose block 20 shown, FIG. 5 in the same manner as shown in the vertical side portion 12 is a general-purpose type block 20 It is the same length as the side part 22, and the horizontal side part 13 is made shorter than the horizontal side part 23 of the general-purpose block 20 to be substantially rectangular.

The end revetment block 1 and the adjustment revetment block 10 shown in FIG. 12 to FIG. 14 are not limited to this, and are fitted to the side walls to fit the general-purpose block 20 according to the laying position. The convex part 24 and the connection reinforcing bar 25 should just be provided.
That is, the end odd occurs revetment surface desired in laying alone general-purpose block 20 shown in FIG. 11, may be substantially satisfy the odd portion in the same manner as described above, for example, the end shown in FIGS. 12 and 13 When selecting and laying the revetment block 1 for the section and the adjustment revetment block 10 shown in FIG. 14 , the joint protrusions 24 are brought into contact with each other and the adjacent connecting reinforcing bars 25 are tightly coupled to each other. By filling the space formed between the block main bodies 2, 11, and 21 with the joint end concrete, the end edge portion of the revetment surface is formed so as to cover the joint end protrusion 24 and the connecting rebar 25. That's fine.
The surface of the general-purpose block 20 is appropriately shaped such as flat, concave, convex, concavo-convex, and pseudo-stone-like, so that the surfaces of the edge revetment block 1 and the adjustment revetment block 10 are also this. It is sufficient that the shape is appropriately adapted to the above.

Further, in the revetment block 1 for the end portion, the front and back surfaces of the block main body 2 are adapted to the surface mode of the general-purpose block 20 (for example, an appropriate shape or pattern such as flat, concave, convex, uneven, pseudo stone-like). In addition, both the front and back surfaces may be the same, and in this case, the revetment surface can be formed by laying the block body 2 with the front surface or the back surface of the block body 2 facing the front depending on the laying location where the half ends occur. In other words, one type of revetment block for end reversal can be used upside down. By using it symmetrically at the left and right end edges and the upper and lower end edges of the revetment surface, the inclined side 4 can be used in place. in it can be exposed respectively symmetrically (metaphorically, edge forming the left shoulder up like a to end edges such a right shoulder up like in the left portion of its in the right portion of FIG. 8 (b) to, or can be formed on the edge that forms a right shoulder up like a to edge portions such left shoulder up shape at the bottom and top of its in the lower part of the upper and FIG (c) in FIG. 8 (b) (respectively (Not shown).), There is an advantage that the number of types of blocks used for the edge processing can be reduced.

For example, if the generic type block 20 to凹模like front view substantially rectangular shape is formed on the surface of the block body 21 at substantially the same structure as that shown in FIG. 11 (not shown) is revetment block for an end portion As shown in FIGS. 15A to 15C , a substantially trapezoidal concave pattern 28 is formed on both the front and back surfaces of the substantially trapezoidal block body 2, and the block body 21 of the general-purpose block 20 is When the surface has a substantially square-shaped convex pattern in front view (not shown), the end revetment block 1 is substantially a base as shown in FIGS. 15 (A), 15 (D) and 15 (E). Convex patterns 29 having a generally trapezoidal shape in front view are formed on both the front and back surfaces of the block main body 2 having a shape. Incidentally, for an end portion revetment block 1 of Figure 15 has a substantially same structure as that shown in FIG. 12.

Further, in the revetment block 1 for the end portion, the front and back surfaces of the block main body 2 are adapted to the surface mode of the general-purpose block 20 (for example, an appropriate shape or pattern such as flat, concave, convex, uneven, pseudo stone-like). In this case, depending on the surface mode of the general-purpose block 20 that forms the main body of the revetment surface, the surface or the back surface of the general-purpose block 20 that is adapted to the front surface is the front side. You can form a revetment surface by laying it. In other words, one type of edge revetment block can be used to reverse the front and back, and can be used on two types of revetment surfaces with different surface aspects, and there is an advantage that end treatment can be performed in various ways.
In particular, depending on the laying location (left and right edge portions and upper and lower edge portions of the revetment surface), for example, an end revetment block 1 that changes direction with its front or back surface facing the front side (shown in FIG. 16 described below) The above-mentioned effect can be obtained by rotating the block body 2 around the intersection of the base portions 3 that form a substantially right angle so that the inclination of the inclined side portions 4 can be converted into a 10% slope at the laying position). prominent and not preferred.

Further, FIG. 16 (A) to the end for revetment block 1 shown in (c) has a substantially same structure as that shown in FIG. 13, a front view substantially on the surface of the block body 2 of a substantially pentagonal shape triangular凹模like 28, front view substantially triangular convex pattern 29 on the rear surface are respectively formed, the surface, the凹模like positive surface as viewed substantially square shape on its surface with substantially the same structure as that shown in FIG. 11 the surface morphology of the formed generic type block (not shown), also the backside, general-purpose blocks convex pattern has been formed in the positive plane when viewed substantially square shape on its surface with substantially the same structure as that shown in FIG. 11 Each is adapted to the surface form (not shown).
Also in adjusting revetment block 10 shown in FIG. 17 (a) to (d), it has a substantially same structure as that shown in FIG. 14, a convex pattern of the front view substantially square shape on the surface of the block body 11 29, a pseudo-tone-like convex pattern 29 is formed on the back surface, and the surface is substantially the same as that shown in FIG. 11, and a convex pattern is formed on the surface in the same manner as described above (not shown). on the surface aspect, the back surface, it conforms respectively to the surface aspect of the cast stone tone generic type blocks convex pattern has been formed (not shown) on its surface at substantially the same structure as that shown in FIG. 11, each end Similar to the revetment block 1 for clubs, it is possible to use the front and back to be compatible with the two types of surface aspects of the general-purpose block.

In each of the above examples, a concave pattern 28, a convex pattern 29, and a pseudo-stone-like convex pattern 29 are formed on the front and back surfaces of the block main bodies 2 and 11 of the end revetment block 1 and the adjustment revetment block 10. However, the present invention is not limited to this, and the front and back surface modes may be the same mode or different from each other, as long as the shape and pattern are appropriately matched to the surface mode of the general-purpose block 20 as described above. .
