<p>PROBLEM TO BE SOLVED: To finely control the rising and falling of an excavating body, at the same time, properly release reaction force received from the bottom of the sea or the water to the excavating body, control lateral pressure applied to a cable and, at the same time, to enable the prevention of damage in the excavating body. SOLUTION: In an embedded machine having a water jet system excavating body 12, the excavating body 12 is longer than the width in the longitudinal length, it is capable of being oscillated to the machine body with the front end shaft 24 as the center and having such a structure as it can be slantly sank to the bottom of the sea, and a link body 44 connecting two arms 44a and 44a with the shaft in a rotatable manner are provided between the excavating body 12 and machine body. A driving cylinder device 46 consisting of cylinder 46a and a piston rod 46b is provided between the machine body and arm 44a of the link body 44.</p> |
