A scour prevention structure for a channel culvert using precast concrete blocks is provided to prevent scour of the channel culvert by connecting precast concrete blocks comprising base blocks and finishing blocks with one another. A scour prevention structure for a channel culvert(C) using precast concrete blocks(B) comprises base blocks(10) and finishing blocks(30). The base blocks are accumulated on the bottom of the channel culvert. Formed like a triangle, the finishing blocks are located at the end of the base blocks and face the channel culvert. Each base block is provided with a square cavity formed from the top to the bottom.
