2. Description of the Related Art FIG. 9 is an explanatory view of a conventional retaining wall (water channel) block. FIG. 9 (a) shows a straight retaining wall (water channel) block W integrally manufactured and a sloped retaining wall. (Waterway) Block WK is shown, but in the case of an outer curve, which will be described later, other than the straight construction, the bottom slab 10 is cut 10c with a diamond saw or a wire saw in accordance with the state of the curved construction, or the formwork is previously formed at the time of manufacturing. It is necessary to remodel the bottom slab to cut dimensions, and since the formwork that integrally forms the retaining wall block upside down is complicated and expensive, avoid damage to the formwork due to remodeling such as steel plate welding, and cut styrofoam ( Disposable)
It is dangerous because it is often necessary to work with people at high places, because it involves mounting at high altitudes. In the production of small quantities of many types, various patterns created each time according to the modification of the height of the front walls 5 and 6 or the demand There is a drawback that it takes time to change the mold and the like, and it is not possible to respond quickly and the product price increases.

A curve construction A shown in FIG. 9 (b) is a case in which the sloped retaining wall (water channel) block WK is constructed on a curve (outer curve) s1 bulging outward, and a lower end of an adjacent front wall. The gap between the portions d is opened to form a gap g, and the bottom slab also has a front opening gap similarly. The curved construction B shown in FIG. 9 (c) is a sloped retaining wall (waterway) block WK.
Is formed on the inwardly curved curve (inner curve) s1, a gap g is formed between the upper ends u of the adjacent front walls, and the bottom slab is similarly formed with a rearward opening gap. It is necessary to consolidate (fill) g with cast-in-place concrete, and a predetermined connection plate jp is also custom-made for each site. With a pattern with a pattern, it is possible to form a pattern without discomfort at the site on the surface of the gap g. It is difficult, and the construction period is prolonged due to the curing period of the part, the construction cost rises, and there are many disadvantages such as the weakened retaining wall constructed due to the gap g. In addition, the code | symbol 4 in a figure is a road or a waterway, and the curve s2 is a curve in which the top end (upper end part) t of a product is inscribed.

FIG. 1 is a diagram showing the configuration of the present invention corresponding to an outer curve A (shown on the left) whose construction curve bulges outward and an inward curve B (shown on the right) which is a reversing curve. The upper part of the outer curve A and the lower part of the inner curve B schematically show an embodiment corresponding to both curves. FIG. 2 is an exploded perspective view showing the configuration of the embodiment (for the outer curve) of the present invention. Is shown. First, a description will be given of the front wall block 50 for the outer curve A, which is manufactured by flattening by dividing. The chord length of an arbitrary size inscribed in the construction curve s1 having the radius of curvature R, that is, the lower width L1
(A standard product is about 2 m, and a product of about 1 m is used for adjusting a laying section or when the minimum radius of curvature R is particularly small, such as 5 m or less.) The lower width L1 both ends a and b and a center of curvature radius o. Has an upper width L2 inscribed in a concentric curve s2 intersecting with the lines ao, bo connecting
0.3] or 5 minute [1: 0.5] gradients are often used. ) Is formed into a flat plate having a length HL (same as the height in the case of a straight wall) satisfying the required height H, and the concentrated stress applied to the connecting portion when the front wall block 50 and the bottom plate block 100 are connected is dispersed. Therefore, in order to strengthen the adhesive force on the fastening member 126 having the threaded portion 125 engraved at one end, a fastening member 120 to which a fixing member 128 such as a perpendicular steel bar or a perforated steel plate is fixed and a threaded portion for fastening are attached. The insert 110 (or the fastening member 121) having the
The threaded portion 125 is exposed and embedded in the concave portion 54 (to facilitate assembly) on the rear side. In addition, since it is manufactured with a flat-molded formwork (placed in a horizontal state), the formwork is simple and inexpensive. Various patterns can be formed on the front surface by a pattern of rubber, urethane resin, etc. By mounting the board, the top edge t matches the vertical slope of the route
The k top end height and the like can be easily formed.
