The seabed ground surveying device is moved to the ground of the seabed by a crane. And when the seabed ground irradiation apparatus is arrange | positioned in a fixed position, it drives a rod feed part and transfers a rod to the centerline side of the through-hole 7a of the base 7.

This will be described in detail as follows.

When the rotary actuator 39 is driven while the rod feed chuck 43 provided to the transfer actuator 41 holds the first rod R, the rotary shaft 37 rotates. Then, the transfer actuator 41 moves the rod R toward the through hole 7a side of the base 7.

At this time, the rod inserting portion 1 pushes the rod R to the bottom of the seabed by the rod inserting means. That is, when the rod R is disposed on a line extending from the through hole 7a of the base 7, the rotating member 21 is rotated by the driving source and the pressing member 23 is rotated according to the rotation of the rotating member 21. Is moved downwards. The rod (R) is then pushed into the seabed.

At this time, the rod guide 13 is in close contact with the rod (R) serves to guide the rod (R) to be inserted into the ground vertically.

Of course, the rod feed chuck 43 moves to the original position by the transfer actuator 41 and moves to the position where the second rod R is located by driving the rotary actuator 39 to catch the second rod R. .

While repeating this process, the rod R can be inserted into the seabed. And through the space provided in the rod (R) it is possible to take the necessary samples or to perform various tests.

In other words, boring, standard penetration test (SPT), pressure meter test (PMT), cone penetration test (CPT), field vane test, FVT), sampling, and coring can be safely performed.

As described above, the embodiment of the present invention can be stably supplied to the rod insert to improve the stability of the work in the extreme environment, thereby reducing the working time and the number of work can be improved productivity.
