Abstract
Sleeve as a protection device that is used around a bridge pier in the laboratory. The sleeve is an axisymmetric, open-ended pipe-like cylindrical enclosure placed concentric to the circular bridge pier. The underlying scour reduction mechanism with the sleeve is to confine the scouring vortex in annular space amid the pier and sleeve. Experiments were carried out on four sizes of sleeves at different vertical locations. After experimentation, it was concluded that as the diameter of the sleeve is smaller than performance potential of the sleeve becomes higher. The sleeve may be able to reduce scour by 56% with reference to an unprotected circular bridge pier. This axisymmetric device is sufficient for huge changes at the angle of flow attack and also workable during floods. Hence, this device provides a scour-free arrangement.
