Abstract

PURPOSE: To indicate continuously a ditch washing degree without the influence of floating materials in water by providing a self-sinking system static pressure detection part consisting of a ring-shaped gun tube and a reference position setting static pressure detection part on the guide cylinder fixed to a bridge leg, etc., and operating the difference of both outputs.
CONSTITUTION: Reference position setting static pressure detection part 8 having pressure converter 9 for static pressure detection and self-sinking system static pressure detection part 10 which has pressure converter 11 for static pressure detection and consists of a ring-shaped gum tube sliding on guide cylinder 6 vertically are provided on the outside circumference of guide cylinder 6 buried in river bed part 22. Static pressure signals detected by detectors 8 and 10 are inputted to adjustable amplifier 2 of signal processor 1 which is installed on the scaffold provided on bridge 20. Then, the difference between both output signals is operaed by adjustable amplifier 2 and is indicated onto indicator 3 as a ditch washing degree and is transmitted from telemeter transmitter and receiver 24 to remove places.
