Claims

[Scope of utility model registration request]

The main cable 10 is constructed by covering the wire cable 14 with a cushioning material 15 made of rubber or synthetic resin, and covering the outer periphery of the cushioning material 15 with a metal flexible protective tube 16. A cable lattice body 6 is constructed, and the main cable lattice body 6 is arranged so as to be located on a plane substantially perpendicular to the debris flow direction, and both ends of the main cable 10 extending in the lateral direction are connected to the reaction force support structure 5. A transparent erosion control dam using a cable net, which is removably connected to the main cable lattice body 6 and has a net 30 made of small diameter cables with lower strength than the main cable 10.
