ABSTRACT:
An anti-scour apparatus and method for preventing, reducing or repairing scour in the vicinity of a structure extending vertically from the floor beneath a body of moving water. The anti-scour apparatus comprises one or more deflectors, a spacer for maintaining the positional relationship of the deflectors and for maintaining the positional relationship of the deflectors and the floor beneath the body of water, and a plurality of hydraulic trips operatively associated with the structure. The method for preventing scour including the steps of deflecting a downwash at a location adjacent the structure and above the floor, deflecting a downwash at a location adjacent the structure and adjacent the floor, inducing the turbulent flow of water adjacent the structure, and capturing the suspended sediment for filling prior scour. Additionally, the invention comprises a kit of parts preferably comprising as cooperative parts thereof an upper deflector, a lower deflector, a sleeve movably and removably engaged with the structure, means for securing the deflectors to the sleeve, and a plurality of hydraulic trips associated with the sleeve.
