Formwork blocks

Abstract

This product is a formwork block used when manufacturing riverbed protection blocks to be installed on the riverbed, and is particularly used in areas adjacent to the slope of the revetment. As shown in the reference perspective view illustrating each part, reference diagram 1 (plan view) illustrating each part, reference diagram 2 (front view) illustrating each part, and reference diagram 3 (plan view) illustrating each part, at the block installation site on the riverbed, this product is erected at two corner positions in a square shape in plan view, on the slope side of the revetment, so that the tapered portion of this product is in contact with the slope. At the other two locations, formwork blocks as shown in the reference perspective view illustrating standard type formwork blocks are erected, and adjacent formwork blocks are connected with formwork plates to form a square-shaped structure in plan view, and concrete is poured into this structure to manufacture the riverbed protection block. As shown in the reference diagram illustrating the state in which revetment blocks are installed on the riverbed, riverbed improvement work is carried out by installing a revetment-type revetment block using this product on the riverbed so that one end is in contact with the slope of the revetment, and another standard-type revetment block is installed in contact with the other end of the revetment-type revetment block, thereby laying down multiple revetment blocks.
