The collecting tank 41 is in an annular structure and is arranged at the bottom of the pressure container 50, so that the dropped residual couplant can be collected by the collecting tank 41 when workers automatically detect different positions of the pressure container 50 by ultrasonic waves, and pollution to the bottom of the concrete platform 54 is avoided.
