Is arranged in the bank body portion 103 at the upper end of the bank body 1.

The slide form 3 is formed on the bank portion 103.
In arranging, the jack bolt 55 is screwed to the nut 57 welded to the upper surface 501 near the lower end of each vertical end thick 5, and the bolt insertion hole 505 penetrating the vertical end thick 5 is inserted. The jack bolt 55 is inserted through the screw bolt 55, and the tip of the jack bolt 55 is projected from the lower surface 503 to the bank 1 side while rotating the jack bolt 55. Then, the protrusion length of the jack bolt 55 from the lower surface 503 is adjusted by rotating the jack bolt 55.

Next, the sea bolt 5 is inserted from the upper surface 501 side into a bolt insertion hole 507 which is provided at a substantially middle portion of each vertical end thick 5.
9 and insert the tip into the bolt insertion hole 105,
A female screw (not shown) at the tip of the seabolt 59 is screwed to the male screw of the embedded anchor 53, and a nut 60 is screwed to the male screw of the seabolt 59 portion protruding from the upper surface 503 of the vertical end 5 and tightened. As a result, the slide foam 3 is attached to the bank body 103, and the metal foam 9 is arranged above the bank 1.

Then, a new embedded anchor 53 is arranged inside the metal foam 9. Embedded anchor 5
In the arrangement of 3, the bolts 61 are inserted from the holder 28 attached to the upper surface 501 near the upper end of each vertical end thick 5 into the bolt insertion holes 509 penetrating the vertical end thick 5 and the The tip is extended to the inside of the metal foam 9, and the male screw of the embedded anchor 53 is screwed to the female screw (not shown) at the tip of the bolt 61. In this state, the holder 28
The pin 2803 is inserted into the pin insertion hole (not shown) of the one side wall 2801, and the pin 2803 is inserted into the pin insertion hole (not shown) of the bolt 61 projecting from the holder 28. By inserting the tip of 2803 into the pin insertion hole (not shown) of the other side wall 2801 of the holder 28, the bolt 61 is prevented from falling out from the bolt insertion hole 509. As described above, the work of disposing the slide form 3 on the bank portion 103 is completed.

When the slide foam 3 is arranged on the bank body portion 103, concrete is placed inside the metal foam 9 for curing, and the new bank body portion 103 is spliced on the bank body portion 103 already constructed. Add When a new bank 1 portion is added to the bank 1, the slide form 3 is removed from the already built bank 101, and the slide form 3 is removed.
Is moved upward, and in this way, a new portion of the dam body 1 is successively added onto the dam body 1.

The slide form moving device 21 is used for attaching and detaching the slide form 3 and for moving the slide form 3 in the above steps. First, a case where the slide form 3 is removed from the already constructed bank 101 will be described. The carriage 23 is driven by the two drive wheels 35A.
Is driven and the carriage 23 is steered by the drive wheel 35A and the remaining two wheels 35, and the slide form moving device 21 is arranged at the end of the bank portion 103. Then, the lateral member 2503 of the swing frame 25 is extended in the width direction of the dam body 1, and the front end of the base 33 is brought close to a position above the edge portion of the dam body portion 103 on the side wall 101 side. The piston rod 2403 of No. 24 is projected from the cylinder body 2401, and the bank portion 103
Fix the carriage 23 on top.

Next, the swinging drive mechanism 27 is operated to adjust the extension length of the piston rod 2703 to swing the swinging frame 25 so that each vertical member 2501 is located on the extension of the side wall 101. Let Then, the holes of the hanging hooks 30 of the respective lifting rods 2901 and the holes of the respective hanging hooks 301 of the slide form 3 are aligned and a pin (not shown) is inserted into these holes, and both the lifting rods 29 are fitted by the pins.
01 and the slide form 3 are connected as shown in FIG. At this time, the foam peeling jacks 31 of the vertical members 2501 are in a contracted state, and the wheels 3103 face the contact plates 5103.

When both the elevating rods 2901 and the slide form 3 are connected, the jack bolts 55 of each of the vertical ends 5 are rotated to separate the tip ends of the jack bolts 55 from the side wall 101. Next, the nut 60 is loosened and the sea bolt 59 is rotated to remove the sea bolt 59 from the embedded anchor 53. Further, the pin 2803 is pulled out from the holder 28, the bolt 61 is rotated, and the bolt 61 is removed from the embedded anchor 53.

Next, the wheel 3103 is moved in the direction away from the vertical member 2501 by the slide foam peeling jack 31. As a result, as shown in FIG. 6, the contact plate 5103 is pushed by the wheel 3103 in a direction away from the side wall 101, and the connecting frame 51 and the side wall 101 are removed.
Is gradually widened from the upper end side of the vertical end thick 5, the metal foam 9 is separated from the side wall 101, and the wheel 52 of the vertical end thick 5 comes into contact with the side wall 101.

After the metal foam 9 is peeled off, the worm gear jack 2903 is used to lift the rod 290.
1 is raised and the slide foam 3 is pulled up along the side wall 101. At this time, the wheel 52 of each vertical end 5 is attached to the side wall 1
01 rolling jack, each jack 3 for peeling slide form
The first wheel 3103 rolls on each contact plate 5103 and onto the metal foam 9, and the slide foam 3 is smoothly pulled up by the rolling of these wheels 52 and 3103.

Then, as shown in FIG. 7, when the slide foam 3 is pulled up until the metal foam 9 is located above the splint body portion 103, the lifting rod 2901 is stopped from rising and the foam peeling jack is stopped. The wheel 3103 of 31 is moved in the direction of approaching the vertical member 2501. As a result, the portion of the metal foam 9 near the lower end is brought into contact with the portion of the side wall 101 above the bolt insertion hole 105 in the additional bank portion 103, and the metal foam 9 extends on the extension of the side wall 101.

After pulling up the slide form 3, the lower surface 5 of the jack bolt 55 for each vertical end thickness 5
Adjusting the protruding length from 03, the levee body part 10 that has been added
The sea bolt 59 is fastened to the embedded anchor 53 of No. 3, the new embedded anchor 53 is fastened to the bolt 61, and the embedded anchor 53 is disposed inside the metal foam 9. As a result, it becomes the same state as in Fig. 5,
The slide foam 3 is arranged on the levee body portion 103 that has been added.

If the slide form 3 is arranged on the levee body portion 103, the suspension hooks 301, 30
The slide form moving device 21 is connected to the outside of the bank body portion 103 from above the bank body portion 103 which is replenished by releasing the connection between them and releasing the fixing of the carriage 23 by the outrigger 24.
To move. After that, concrete is placed inside the metal foam 9 and cured to add a new dam body portion 103, and thereafter, the slide foam 3 is removed from the already constructed dam body portion 103 by the same procedure as described above. The slide form 3 is pulled up by the moving device 21, and the pulled up slide form 3 is attached to the bank body portion 103 to which the slide form 3 is added.

As described above, according to this embodiment, the bogie 23 is fixed on the bank 1 by the outriggers 24, and the swing frame 25 is extended so as to extend on the extension of the side wall 101 of the bank 1.
In this state, the elevating rod 2901 and the slide form 3 are connected, the metal foam 9 is separated from the side wall 101 by the foam separating jack 31, and the elevating rod 2901 is lifted by the worm gear jack 2903 to slide the slide form 3. The slide form 3 was moved by pulling up. Therefore, compared to the conventional method in which the slide form 3 is lifted by a crane, a skilled operator is not required, and the work of moving the slide form 3 can be efficiently performed in a short time. Further, unlike the conventional case, it is not necessary for an operator to look down on the slide form 3 being pulled up from the bank 1, and to give a motion or voice to the operator of the slide form moving device 21. It is not necessary to arrange a worker on the upper edge of the body 1, and the work of moving the slide form 3 can be performed safely.
