Formwork blocks

Abstract

This product is a formwork block used when manufacturing riverbed protection blocks to be installed on the riverbed or coastline. As shown in Reference Diagram 1 (Plan View), Reference Diagram 2 (Front View), and Reference Diagram 3 (Plan View) illustrating the usage of each part, the formwork blocks of this product are erected at the corners of a square-shaped area in the riverbed where the blocks will be installed. Adjacent formwork blocks are connected with formwork plates to form a square-shaped structure in the plan view, and concrete is poured into this structure to manufacture the riverbed protection blocks. Then, as shown in the reference diagram illustrating the state in which the riverbed protection blocks have been installed on the riverbed, riverbed improvement work is carried out by laying multiple standard-type riverbed protection blocks using this product and revetment-type riverbed protection blocks with one end in contact with the slope of the revetment on the riverbed.
