Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for attaching an anchor plate to the tip of a plastic drain material in a plastic drain construction method, and more specifically, a plastic drain material with an anchor plate attached thereto is struck by a mandrel on soft ground to improve the ground. The present invention relates to an anchor plate attachment device in a plastic drain method used when attaching an anchor plate to the tip of a plastic drain material in the plastic drain method.

[0002]

2. Description of the Related Art A plastic drain method is known as one of the methods for improving a water bottom (sea bottom) ground on which a slurry-like soft mud layer such as sludge is deposited. In this plastic drain method, as shown in FIGS. 14 and 15, a guide frame 4 is arranged to be vertically movable along a guide 3 supported by a tower 2 provided on the hull 1 of a work boat. Using the guided mandrel 5, a plurality of plastic drain materials 7 having anchor plates 6 attached at their tips are placed in the soft mud layer 8 at predetermined intervals.
This plastic drain material 7 sucks out the moisture in the soft mud layer 8 and solidifies the formation.

[0003]

In the plastic drain construction method as described above, the mandrel 5 is used to drive the plastic drain material 7 onto the soft ground 8, and then the plastic drain material 7 is cut on the soft ground 8. In order to mount the anchor plate 6 for driving the cut plastic drain material 7 at the next predetermined position, the mandrel 5 and the plastic drain material 7 are pulled up to the top of the hull 1, and a worker manually carries out the mounting work. Since it is carried out, there is a problem that not only a great deal of time and labor is required for the work, but also work on the hull is dangerous.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. A plastic drain material having an anchor plate attached thereto is driven by a mandrel on soft ground to improve the ground. In the plastic drain construction method, the main body through which the mandrel penetrates is attached to the bottom of the guide frame that guides the mandrel,
Anchor plate in a plastic drain construction method in which an anchor plate storage unit, a plastic drain material positioning device and a cutting device, an anchor plate takeout device for the anchor plate storage unit, and a joining device between the plastic drain material and the anchor are attached to this main body. A mounting device is provided.

[0005]

[Operation] According to the anchor plate mounting device in the plastic drain construction method of the present invention, the plastic drain material cast on the soft ground is cut in water slightly above the soft ground, and the plastic drain material is positioned at that position. As the cutting is performed, the anchor plate is supplied and the anchor plate is joined to the tip end of the cut plastic drain material. Therefore, since the plastic drain material can be driven to the next predetermined position without pulling the mandrel and the plastic drain material onto the hull, not only can the driving work be performed quickly, but also automation can be facilitated, which is dangerous. Work can be omitted and labor can be saved.
