PROBLEM TO BE SOLVED: To permit to perform revetment lining having a stable strength by installing wire netting at the front portion and side portion of box-shaped concrete frame bodies and attaching suction prevention sheets to the rear surface portion and bottom surface portion of the bodies. ;SOLUTION: Suction prevention sheets are attached to the rear surface portions and bottom surface portions of rectangular parallelepiped box-shaped concrete frame bodies and also wire netting 2 to the front portions, rear surface portions and bottom surface portions respectively. In addition, a flat lid is projected out at the front surface portion thereby forming a rectangular parallelepiped revetment cage 5; a plurality of cages 5 are connected together with coupling fittings and the inside of each cage 5 is filled up with stone 6. The cages are stacked and gradually set back as the number of the cages stacked increases. Next, rectangular front surface frames, partition frames and rear surface frames of the box-shaped frame bodies are mutually connected with coupling fittings, and the main reinforcement and reinforcing bars are arranged in the concrete frame bodies. Then, a plurality of revetment cages 5 are coupled with coupling fittings at the shore line of a river or the like, and lining work is performed on the top of the cage as required. In this way, the rigidity and strength can be greatly increased compared to iron wire cages.;COPYRIGHT: (C)2000,JPO
