Description

  The present invention relates to a rod conveying device for application to a submarine seating type boring machine that performs excavation while being seated on the seabed for geological survey of the seabed ground.

  When conducting geological surveys of the seabed ground, the boring machine is lowered and seated on the seabed, and then the grounding excavation is performed by remotely operating the boring machine from the ship. In such excavation of the submarine ground, it is necessary to add the rod to reach the target depth in the same manner as excavation on the ground. For this reason, a rod container that holds multiple rods is built into the boring machine.However, unlike ground excavation, it is difficult to take a large space for excavation on the sea floor. The rod is held so as to be parallel, that is, vertically placed, and the rod in the vertical state is moved to the drill head to add the rod.

  By the way, although the seabed boring machine which employ | adopted the revolver type rod container is proposed (for example, refer patent document 1), the sample of the target depth (for example, the range of several m-a dozen m or more) is taken from the seabed. When collecting samples, a revolver type rod container with a dozen or more rods may be sufficient. For example, when collecting samples to a depth of 40 m to 50 m, if trying to increase the number of rods, There is a problem that the diameter of the revolver type rod container becomes large and the submarine boring machine becomes large.

  In addition, when collecting only one sample, the above-mentioned submarine boring machine may not have any problem. For example, instead of collecting only one sample, samples from the surrounding points are also collected. In this case, it is difficult to cope with a revolver type rod container.

  Furthermore, sample collection assumes, for example, a seabed with a depth of about 3000 m. Therefore, a sample is taken by inserting a seabed boring machine into the seabed at a depth of 3000 m from the mother ship, and sampled from the seabed at a depth of 3000 m. It takes more than a few days to collect the submarine boring machine on the mother ship, and it requires a lot of electric power. Therefore, it is wise not to throw in the submarine boring machine or to collect it frequently.
