Abstract
PURPOSE: To realize a high-accuracy measurement and facilitate an easy maintenance for scouring, by providing the ultrasonic transmitter/receiver into a hollow and long pile-shaped member along with a plurality of small windows provided on the side wall of said member and then burying the member into the riverbed or the like to detect the reflection of the ultrasonic wave given from the inside earth and sand surface and thus know the state of scouring.
CONSTITUTION: A plurality of vertically long small windows 15 are provided on the side wall of the hollow and long pile-shaped member 8 having a sharp tip, and the ultrasonic transmitter/receiver 12 is fixed with the supporter 19 in the window 15 with the lower side put down to be connected to the ultrasonic transmitter/receiver by the signal cable 9. Such member 8 is buried upright and close to the bridge pier 1. In this case, the depth of burying is set so that the limiting point 13 of scouring is identical to the riverbed 6 during scouring. Then the earth and sand 16 is filled from the top of the member 8 to bury the transmitter/receiver 12 with earth and sand 16. When the scouring proceeds up to the limit 13 of scouring, the sand 16 flows out. Thus the state of scouring can be measured with high accuracy from the time interval between the transmission and reception of the ultrasonic wave. At the same time, the maintenance is facilitated for the detecting system.
