[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a landscape formwork on a slope such as a dam (concrete dam, sabo dam) or sloping ground, and a landscape formwork block used in this method.

[0002]

2. Description of the Related Art Conventionally, concrete is cast using a steel or wooden formwork to form a scenic formwork on the first stage, and after the concrete is cured, a second-stage formwork is arranged. After that, concrete has been poured and then a method of constructing a scenic formwork in a stepwise manner has been carried out in the same manner.

[0003] In the above-mentioned construction method, it is necessary to install a formwork and cast concrete for each step, and this is an inefficient construction method. Therefore, a remodeling formwork method using blocks previously manufactured in a factory is performed. It became as to be. For example,
Japanese Patent Application Laid-Open No. -6018 discloses a square-tube-shaped reinforced concrete made up of a front and rear wall and both side walls, and provided with a vertical protruding wall having a fitting recess at at least one of a front wall lower end surface and a rear wall upper end surface. A plurality of blocks are horizontally arranged in a single row or multiple rows to form a first row of blocks, and the interior of these blocks is filled with earth and sand. The second row of blocks is stacked in a state where it is appropriately spaced rearward and fitted and locked to each other via the fitting recess of the protruding wall, and the hollow interior of each block of the block row is mounted. This step is repeated to form a stepped retaining wall composed of a plurality of block rows, and the earth and sand filled in each of the block rows exposed on each horizontal step surface of the stepped retaining wall. Characterized by planting trees to build a landscape formwork Greening block retaining wall construction method has been described.

Japanese Utility Model Publication No. 58-3873 discloses that
Left and right symmetrical hollow column-shaped concrete blocks open in the vertical direction surrounded by left and right side walls b, b and front wall c and rear wall d that are convex toward the front,
When the convex front wall c is stacked appropriately in such a manner that the blocks in the depth direction and the frontage direction are stably supported at least at three places on one of the upper blocks on the two lower blocks. And a vegetation space having a substantially rhombic cross section can be formed between the steps, and at least two of the three support points are connected to the upper and lower blocks so that upper and lower blocks are fitted and fixed. A hollow column type block for constructing a green soil retaining wall having a concave portion and / or a convex portion appropriately provided at a lower end portion is described.

[0005] In the above two landscape formwork blocks,
This is an aspect in which the soil is formed in the entire block without the partition wall in the landscape formwork block according to the present invention.

[0006]
