Abstract: An intercepting net based on reversing current motion at a river bottom, including a net body connected to ropes arranged in a crisscross manner, an anti-floating and anti-drifting rope and a mounting frame. A top of the net body is connected to a main rope and an auxiliary rope arranged side by side. The anti-floating and anti-drifting rope includes lead-core ropes arranged in a crisscross manner and connected to the ropes. The net body includes a vertical interception portion, whose bottom is connected to a first anti-escape net portion extending in a first direction and a second anti-escape net portion extending in a second direction opposite to the first direction. First anti-floating and anti-drifting chains are sequentially fixed on the first anti-escape net portion along the first direction. Second anti-floating and anti-drifting chains are sequentially fixed on the second anti-escape net portion along the second direction.
