  Furthermore, as shown in FIG. 8 and FIG. 9, since the small floating float carrier 11A is connected to form a plurality of small float carrier ships 10A, for example, the construction on the mud of the soft ground 1 in the marshes is carried out. It is suitable for use in In this case, a plurality of small floats 11A, a disassembled drain material placing machine 20 and the like are divided into a plurality of trucks and transported to the site for land transportation, and the site is connected and assembled to place the drain material placing machine 20 etc. The placed base vessel 11 is floated on the mud of the soft ground 1, and is pulled by a plurality of on-land winch devices 8 to a construction site on the mud by a plurality of ship handling wires 9.

  Next, the procedure of the construction on mud by the drain material driving work boat 10 of the embodiment will be described.

  First, move the winch device 8 on land wirelessly while looking at the GPS measurement device positioning monitor (not shown), as shown in FIG. 8 and FIG. Move to the position). At this time, the drain material placing machine 20 on the charter vessel 11 stands by at a predetermined position. Further, with the spuds 45, 45 on both sides of the stern of the cruise ship 11 raised, the cruise ship 11 is moved to the placement position.

  Then, the horizontal drain material 6 is pulled out from the horizontal drain material supply reel 38 in one of the work scaffolds 30 of the work scaffold 30, and on the plurality of drain hooks 36 juxtaposed on the back side of the main scaffold 31 of the work scaffold 30. It lays over the full length of the main scaffold 31.

  Further, the horizontal drain material 6 is further drawn from the horizontal drain material supply reel 38 of one cross scaffold 33 to the other cross scaffold 33 on the opposite side, and the end portion of the horizontal drain material 6 on the other cross scaffold 33 And engage with and connect to the end of the horizontal drain member 6 in the adjacent already-placed area (finished area). At this time, the connected horizontal drain material 6 is installed so as to straddle the marine vessel maneuvering wire 9.

  Furthermore, the movable carriage 21 of the drain material placing machine 20 is moved close to the horizontal drain material supply reel 38 side and the work bench 40 side of the vessel 11, and the other end 44b of the spud lifting wire 44 is moved. 6 so as to move the movable carriage 21 in the direction of the arrow Y in FIG. 6 so that the spud 45 is slightly lifted as shown in FIG. 6, and the spud fixing pin 46 is penetrated by the spud 45. Pull out from hole 45c.

  Then, by moving the movable carriage 21 of the drain material placement machine 20 in the direction opposite to the Y direction, the spud 45 descends by its own weight and penetrates into the soft ground 1 as shown in FIG. The other spud 45 on the workbench 40 of the small float carrier 11A on the other end side also moves the movable carriage 21 of the drainage material placing machine 20 to the small float carrier 11A on the other end side, and performs the same operation. Penetration into soft ground 1 Thereafter, the drainage material placing machine 20 is moved to the small float carrier 11A on the other end side (the opposite side of the horizontal drainage material supply reel 38) which is the placing start end, and placing is started.

  That is, an anchor 3 (shown in FIG. 11) is mounted on the vertical drain material 2 guided from the upper side of the casing pipe 27 of the drain material placing machine 20 through the inside of the casing pipe 27 to the lower end. As shown in FIG. 10, FIG. 10 and FIG. 11, with the casing pipe 27, the vertical drain material 2 is driven into the soft ground 1 to a predetermined depth. After this, the casing pipe 27 is pulled out, and the remaining position of the vertical drain material 2 is confirmed. As shown in FIG. 3A, the vertical drain material 2 is located at a position where the vertical drain material 2 is exposed 100 cm or more on the original ground. Cut.

  Next, the upper end 2 a of the vertical drain material 2 and a predetermined position of the horizontal drain material 6 are connected (joined) on the main scaffold 31 of the work scaffold 30 and dropped onto the soft ground 1. The placing operation and the connecting operation of the vertical drain material 2 are sequentially performed up to the placing end while moving the drain material placing machine 20 by a predetermined pitch to the placing end and setting at each placing position. And the horizontal drain material 6 which finished the connection operation | work of several vertical drain materials 2 is sequentially removed from the hook 36 for drains attached to the downward side of the main scaffold 31, and is laid on the ground surface.

  When all the vertical drain members 2 have been cast, the horizontal drain member 6 is cut from the horizontal drain member supply reel 38. At this time, the connection allowance with the adjacent horizontal drain material 6 is sufficiently taken. Furthermore, simultaneously with the completion of the placement of the vertical drain material 2, on the bow extension scaffold 32 of the work scaffold 30, bonding is performed with an adhesive tape so that the tip portion of the horizontal drain material 6 of the previously constructed lane becomes a loop. Be cured.

  In addition, as shown in FIG. 3 (b), when the vacuum consolidation method is adopted, the drainage hose 4 with an airtight cap connected to each vertical drain material 2 between each lane is not used without using the horizontal drain material 6. Although connected by the water collection pipe 5, this operation is also performed on the main scaffold 31 of the work scaffold 30.

  Next, after the vertical drain material 2 is completely driven, the other end 44b of the spud lifting wire 44 is connected to the hook portion 21a of the movable carriage 21 of the drain material placement machine 20, and the movable carriage 21 is moved. The spud 45 is moved to the opposite side to lift the spud 45 to a predetermined height. Then, the spud fixing pin 46 is penetrated through the through hole 45 c of the spud 45 to fix the spud 45 to the square cylindrical support 41. Next, the spud 45 set on the other end side of the stern of the vessel 11 is also fixed in a lifted state by the same method, and the vessel 11 is moved to the next placement position.

  As described above, according to the drain material driving work ship 10, the work scaffolding 30 is projected to the outside from the main scaffolding 31 attached to the deck vessel 11 via the setting space K and the main scaffolding 31. It is composed of the attached bow extension scaffolding 32 and the bridge scaffolding 33, and the main scaffolding 31 and the bow extension scaffolding 32 are provided at a position lower than the deck of the cruise ship 11, so that it is horizontal with the vertical drainage material 2. Various operations such as connection work of drain material 6, cutting of vertical drain material 2, work of attaching anchor 3, and curing work of horizontal drain material 6 can be performed smoothly and efficiently by scaffolding according to application. As a result, it is possible to further improve the workability.

  Further, by providing the drain hooks 36 for suspending the horizontal drain material 6 on the lower vessel 11 side of the main scaffold 31 of the work scaffold 30, the horizontal drain material 6 precedes the placement of the vertical drain material 2, It can be suspended in a state of being extended below the main scaffold 31, and troubles such as twisting of the horizontal drain material 6 do not occur, and the laying operation of the horizontal drain material 6 can be performed efficiently. Furthermore, since the horizontal drain material 6 is suspended under the support arm 35 which supports the main scaffold 31, it becomes possible to drop and lay the horizontal drain material 6 on the ground surface as it is.

  Furthermore, since the bow overhanging scaffold 32 further protrudes on the opposite side of the boat 11, the curing operation of the tip portion of the horizontal drain material 6 can be performed in parallel when the vertical drain material 2 is driven. it can.

  Further, according to the drain material driving work boat 10, the movable carriage 21 and the spud 45 of the drain material placing machine 20 are detachably connected by the spud lifting wire 44, and the movable carriage 21 of the drain material placing machine 20 is By moving the spud 45 upward with respect to the square cylindrical support 41 of the work table 40 of the vessel 11 by movement, the existing power of the spud 45 being a traversing movement device of the drainage material placing machine 20 is used. Therefore, the winch dedicated to the spud as in the prior art becomes unnecessary, and therefore, weight reduction and cost reduction can be achieved. As a result, during the placement of the vertical drain material 2 by the drain material placement machine 20, the boat 11 can be reliably fixed by the spud 45. In particular, a great effect can be obtained in a construction area with water depth. Furthermore, in the construction on the mud, the surface of the soft ground 1 is inclined and positioning of the chart boat 11 is difficult, and the position shifts during construction, but since the chart boat 11 can be reliably fixed by the spud 45 Even if the surface of the ground 1 is inclined, the position of the vessel 11 does not shift during construction.

  Further, since the spud 45 is lowered by its own weight to land and penetrate the soft ground 1, an extra power source is not required. Furthermore, since the one end 44 a of the spud lifting wire 44 is connected at the lower end of the spud 45, a large support is not required. As a result, since the total weight of the vessel 11 is not significantly increased, the conventional winch device 8 can be used, and it becomes unnecessary to reinforce the hull of the vessel 11. Furthermore, by forming the spud 45 with an H-shaped rod-shaped steel material, the weight of the spud 45 can be reduced accordingly.

  Furthermore, when it is desired to rotate the boat 11 in the positioning operation of the boat 11, the spud 45 on one side is driven into the soft ground 1, and the boat steering wire 9 stretched on the other side is pulled by the winch device 8, The barge 11 can be rotated, and position adjustment at the time of movement to the placement position can be performed easily and in a short time.

  Further, a plurality of through holes 45c are formed in the spud 45, and the spud fixing pins 46 are penetrated through the plurality of through holes 45c and locked to the upper end 41a of the square cylindrical support body 41. The spud 45 can be easily and reliably fixed to a predetermined position of the square cylindrical support 41.

  In addition, according to the embodiment, although the case where the drain material implantation work boat is used for the construction on the mud of the soft ground of the marshy area was described, the drain material implantation work boat is used for the super shallow soft ground It may be applied to shallow water surface, shallow water surface construction and construction of clay.

  Further, according to the embodiment, the spud lifting wire whose one end is coupled to the lower end of the spud can be lifted from the lower end side of the spud via the upper pulley attached to the upper portion of the cylindrical support. However, the upper pulley may be disposed above the spud, and the spud may be lifted from the upper end side by a spud lifting wire coupled to the upper end of the spud.
