Abstract
Abstract This invention relates to a device to protect local scour around submarine foundation. Piles are commonly used in river and ocean engineering to support structures on top of the water surface. The examples of pile structures including bridge piers, legs of offshore platforms, foundation of wind farms. When a vertical circular pile is placed on an erodible bed, the amplification of the water flow velocity leads to local scour of the sediment around the structure. Local scour has attracted much attention because it is one of the main reasons that may cause structural failure in both bridge engineering and offshore engineering. By using this device properly, local scour around submarine foundation can be reduce up to 50%. Fig. 1
Description
Piles are commonly used in river and ocean engineering to support structures on top of the water surface. The examples of pile structures including bridge piers, legs of offshore platforms, foundation of wind farms. When a vertical circular pile is placed on an erodible bed, the amplification of the water flow velocity leads to local scour of the sediment around the structure. Local scour has attracted much attention because it is one of the main reasons that may cause structural failure in both bridge engineering and offshore engineering. A new device is invented to protect local scour around submarine foundation.
By using this device properly, local scour around submarine foundation can be reduce up to 50%.
Fig. 1 shows the sketch of this device. Submarine foundation is protected by using four short piles.
Claims (2)
- The claims defining the invention are as follows:1. A device to protect local scour around submarine foundation.
- 2. Diameter of the short pile is the same with the main pile and gap between the short pile and the main pile is one diameter of the main pile.
