BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a large number of vertical drain materials are deeply driven into dredged soil / soft ground, and the vertical drain materials are connected to a horizontal drain material or a horizontal drain layer so that the water in the soft ground or the dredged soil is connected. The present invention relates to a drain material driving work ship for drainage improvement of soil using drain material.

[0002]

2. Description of the Related Art Conventionally, in order to improve the drainage of dredged soil / soft ground by the dredging / ground improvement work of the soft ground such as the dredge, the lake, the swamp, and the anchorage surrounded by the dam body / caisson.・
A method has been developed in which a large number of vertical drain materials are embedded in soft ground and water is drained to the outside through the vertical drain materials. This vertical drain material is used for dredged soil and soft ground.
A large number are driven at a pitch of 8 to 2.5 m. In the conventional soft ground improvement method using drain material, a net is laid on the soft ground having a depth of several meters to 45 meters, and sand is filled on the net to a thickness of 0.8 to 2.5 meters. To form a horizontal drain layer, and to give enough supporting force for the self-propelled work machine to travel, then run the self-propelled vertical drain material driving work machine on the embankment and drive in a large number of vertical drain materials. The vertical drain material is pierced and connected to the horizontal drain layer of sand, after which loading embankment is performed. Water and liquid in the soft ground are discharged to the outside through the vertical drain material and the horizontal sand drain layer. After being drained and consolidated, it forms a supporting ground with sufficient strength. The drain material driving work vessel used in this method is a self-propelled vertical drain material driving machine having a vertical post of 20 to 50 m erected and a vertical drain material driving device installed on the vertical post. Multiple machines are fixed on the deck of the ship. For the work, the entire hull of this drain material driving work ship is 0.8
~ 0.8m in lateral direction after moving / stopping every 2.5m
One row of vertical drains is driven every 2.5m, and after the row of vertical drains is driven, the entire hull is 0.8-2.
It is to improve the ground in a wide area by repeating the forward movement of 5 m. In this drain material driving work boat, the entire hull is moved in the left-right direction a number of times every 0.8 to 2.5 m.
It takes a lot of labor and time to move the hull to stop the ship, and the hull movement is inaccurate, and the vertical drain material driving position is inaccurate. Furthermore, this construction method cannot be adopted because it is difficult to move the hull during construction work on mud. Even if this vertical drain material driving method is used in mud construction, the range of vertical drain material that can be driven is only within the width of the hull, so the area where the vertical drain material has been driven first has been completed. The vertical drain material in the vicinity of the boundary between and can not be driven unless the hull is set on the vertical drain material in the vicinity of the boundary of the previously driven area. Therefore, in the case of mud construction, it was practically impossible to drive the vertical drain material near the boundary of the already driven vertical drain area.

In order to facilitate the connection work between the vertical drain material 2b and the horizontal drain material 11, the position of the work deck 2g is adjusted by operating the cylinder 2j so as to approach the mud surface. After that, while the horizontal drain material 11 is being fed out, the traverse base 4 is traversed in the left-right direction and stopped at the next driving position, and the same driving and cutting of the vertical drain material 2b, attachment of the anchor plate, and connection with the horizontal drain material 11 are performed. Work is performed (see FIGS. 6C and 6D). Thereafter, the vertical drain material 2b is driven from one side at a pitch of 0.8 to 2.5 m by the same procedure, connected to the horizontal drain material 11 and connected to the underdrain 13 (see FIGS. 6, 7, 11, and 12). . In this way, after separating the horizontal drain member 11 to which the vertical drain members 2b that have been driven in a row are connected, the entire barge 1 is advanced to the next driving position by using the winch device 5 and stopped at this position. (See FIGS. 7 (e) and 7 (f)), the vertical drain member 2b is driven in from one side and connected to the horizontal drain member 11 in the same manner as before and after (see FIGS. 7 (g) and 7 (h)). In this way, by driving a plurality of vertical drain members 2b in each row in the left-right direction, connecting them with the horizontal drain members 11, and then further advancing the pontoon 1 repeatedly, a large number of vertical drain members 2b are placed on the soft ground B. Drive the horizontal drain material 11
Connect with. As a result, the vertical drain material 2b, which is driven into the soft ground at a pitch of 1 to 2 m in the left-right and front-back directions, as in the region of the soft ground on the right side of FIG.
Connect them and extend them to the underdrain 13 to construct a drain drainage channel. Moisture in the soft ground rises from the vertical drain material 2b, is drained to the underdrain 13 through the horizontal drain material 11 and is compressed and settled so that the dredged soil C is put on the horizontal drain material 11 (Fig. 10 (c)). reference). The water of the soft ground B is drained through the vertical drain material 2b and the horizontal drain material 11 to cause consolidation settlement, and the ground strength of the soft ground B is improved.

The drain material driving work vessel A is arranged at a position slightly away from the boundary of the constructed area, and the winch device 5 is installed along the boundary of the drain material driving work vessel A so that the barge 1 does not come into contact with the constructed drain material. Move with. The transverse base 4 is moved to the left and right extension parts of the rail 3, the vertical drain material driving machine 2 is moved to this boundary area, the vertical drain material 2b is driven into the boundary area, and the horizontal drain material 11 already installed is connected. By using the extension portion of the rail 3 in this way, the work of laying the drain material in the boundary area can be performed without damaging the drain material that has already been constructed. Further, even if the forward movement of the pontoon 1 shifts slightly to the left or right or meanders forward, the traverse base 4 is traversed and the vertical drain material driving machine 2 is moved to an accurate driving position.
By moving, the vertical drain material 2b can be accurately driven. Further, the connection between the regions of the horizontal drain member 11 can be easily performed.
