Claims

[Scope of utility model registration request]

A pressure sensor 5 for measuring water pressure, a weight part 4 having the weight to sink the sand layer by its own weight, a main column 11 to which the weight part 4 is attached, and a main column 11 attached to the lower end of the main column 11. A bifurcated support portion 12;
A sensor section 1 comprising a wave transmitter 2 and a wave receiver 3 disposed at opposing positions of the bifurcated support section 12; a winch section 6 that suspends the sensor section 1 into the water with a wire 10; A sand layer detector 8 generates an ultrasonic signal to be supplied to the transmitter 2 and amplifies the ultrasonic reception signal from the receiver 3 to detect the received wave level; A sand thickness measuring device comprising a measuring device main body 9 for calculating the sand layer thickness at the bottom of the water and the top water depth from the received wave level and the water pressure value output from the pressure sensor 5.
