PURPOSE: A natural river floor structure and a construction method thereof are provided to improve the construction performance by directly being constructed using a grid net and aggregate in a field. CONSTITUTION: A natural river floor structure comprises a plurality of grid nets(10), a plurality of stone nets(20), a coupling member(50) and a fishway block. The grid net surrounds the aggregate and maintains a stone net-shape which has the aggregate in a fixed unit. The stone net is combined on the top of the grid net and exposes the natural stone or the artificial stone by coupling the natural stone and artificial stone in one side to outside. The coupling member couples the grid net and stone net. The fishway block offers the space in which the fishes easily move. |
