PROBLEM TO BE SOLVED: To provide a multi-natural type revetment structure harmonized with a natural environment and a revetment block taking the construction ecosystem into consideration.;SOLUTION: The revetment structure 1 taking the ecosystem into consideration is so constituted that a revetment slope 4 including the area 5 is constituted of a front wall slab 7, a supporting leg 8 and a buttress slab 9 parallel with the front wall slab 7, the revetment block 2 having a projection 12 of the diagonal direction 11 in one corner 10 of the front wall slab 7, the front end shape 17 of the projection and a partial recess shape 19 having the same shape as that of a side shape 18 in the remaining three corners 14, 15 and 16, a through-hole 29 of the front wall slab 7 and a slit forming recessed section 20 on the side of the front wall slab 7 and a large number of end section revetment blocks 2a without the projection overhanging to the end side for the revetment structure end section or a large number of corner revetment blocks 2b are arranged in the same direction, the projection 12 is fitted to the partial recess shape 19 of the upper neighboring revetment block 2, the backing 27 of gravel 25 is made to the revetment slope 4 on the back 24 of the buttress slab and that the filling 30 of the gravel 25 is made on the circumference of the supporting leg 8 between the front wall slab 7 and the buttress slab 9 and inside of the slit 31 between the inside of the through hole 29 and the neighboring revetment block 2.;COPYRIGHT: (C)2002,JPO
