Abstract
PURPOSE:To enable move and installation to be made easily and to prospect the ground construction accurately by connecting the mainstay of means for generating shearing waveform to a movable running means and by striking an oscillation board connected to the lower part of the mainstay with a hammer. CONSTITUTION:A shearing waveform generation unit 1 used for elastic waveform prospect which performs prospect of ground construction is moved to a point which is an oscillating point by a running means 2. Then, a shearing waveform generation means 3 is installed vertically to the ground face by operation of upper and lower piston rods 2a and 2b and arm 2c and an oscillating board 6 is pushed up to the ground face by means of means 3 and upper level pressure of weight 2 by floating the front wheel 2d of means 2. An oscillating board 6 is connected to the lower part of mainstay 4 of the means 3 through a rubber damper 5 and a hammer 8 is pivoted to the angle of upper part of the mainstay 4 so that it can freely move. A piston rod extended from the hydraulic cylinder 9 which was fixed to the mainstay 4 is pivoted to the arm part of hammer 8 so that it can move freely. In this manner. The ground construction can be accurately prospected.
