PROBLEM TO BE SOLVED: To use a cage main body for a straight line part to construct a cage mat lining for a curve part by superposing L-shaped cage main bodies formed by bending a turtle shell wire net one on the other, and arranging and connecting the same along a curve part. SOLUTION: In a straight line part, one end of a turtle shell wire net is bent to form an L-shaped cage main body 2 comprising a side net 3 and a bottom net 4, the cage main bodies 2 are connected to each other rectilinearly by a fitting 11 formed by a spiral iron wire, and partition nets 6 are connected to both side parts and the central part by the fitting 11 to form stone filling spaces having the open upper surface. In the curve part, the cage main bodies 2, 2 are superposed and arranged along a curve, and connected to each other by the fitting 11, the patition nets 6 adjusted to a required length are connected to form a trapezoidal spaces. After the spaces are filled with stone, a covering net is put thereon to end the cage mat lining. Accordingly, the cage mat lining for the curve can be constructed by using the same material as that for the straight line part.
