The invention discloses an anti-scour turbulent flow mechanism for a bridge pier, and relates to the technical field of bridge pier protection, the anti-scour turbulent flow mechanism comprises a turbulent flow assembly, the turbulent flow assembly comprises a turbulent flow cover arranged on one side of the bridge pier, a base plate is fixed on one side of the turbulent flow cover, a flow guide plate is fixed on the top of the base plate, and a ground cone is fixed on the bottom of the turbulent flow cover; and the downward pressing assembly is arranged on one side of the bridge pier and comprises a connecting piece arranged on the bridge pier. The device has the beneficial effects that through cooperation of the turbulent flow assembly and the downward pressing assembly, the turbulent flow cover and the base plate are attached to a riverbed to achieve foundation turbulent flow anti-scouring, the guide plate guides water flow to the two sides of the pier to reduce direct scouring, meanwhile, a sleeve can be pushed through an adjusting rod, a driving gear and other structures of the downward pressing piece, and the turbulent flow cover is driven to move downwards; the problem that the lower portion of the turbulent flow cover is emptied after a riverbed is scoured is effectively solved, the turbulent flow cover is tightly attached to the riverbed all the time, the situation that riverbed soil loss is accelerated after the turbulent flow cover is suspended is avoided, and the anti-scour effect of the bottom of the pier is greatly improved.

The ecological slope protection structure comprises a positioning block, a connecting table, a slope protection body, a planting end and separation rods, the positioning block is welded to the lower end of a connecting flat plate, the side end of the surface layer of the connecting flat plate is fixedly connected with the slope protection body, and the planting end is arranged at the top of the slope protection body; the separation fences are installed on the side edges of the planting ends and fixedly connected with the slope protection body. After the connection platform is further improved, a large amount of rainwater blocked on the slope protection body can be led out through the channel of the bearing platform and the guiding structure, and therefore the rainwater can enter the guiding groove through the intercepting net of the guiding structure and then be drained; therefore, the situation that the slope protection body is washed away due to accumulation of a large amount of rainwater after extremely heavy rainfall can be avoided, the use strength and the drainage effect of the slope protection structure are further improved, and meanwhile the situation that a large amount of soil is lost can be avoided according to the intercepting net.
