[0006] The carriage 2 is formed of a rectangular plate-like underframe, and as shown in FIG.
The inverted L-shaped weir plate 4 turns the space surrounded by the two sides outward,
The upper end is horizontally connected via a vertical hinge 3, and the lower end of the inverted L-shaped weir plate 4 is provided with a tip of an adjusting screw rod 5 fixed to both long sides of the bogie 2 at a predetermined angle. Are connected. A U-shaped wheel mounting frame 6 fixed in parallel at a predetermined interval in the short side direction is provided on the lower surface of the bogie 2.
The wheel 1 is fixed to the front and rear of the wheel mounting frame 6, respectively, as shown in a state where the cart 2 is raised by 90 °. The wheel 1 is mounted on the wheel mounting frame 6 on the reverse L-shaped weir plate 4 side. Two guide rollers 8 are fixed before and after the guide roller mounting plate 7 with the guide roller mounting plate 7 interposed therebetween in a direction orthogonal to the wheel 1. In addition, on the upper surface of the trolley 2, two rings 9 used to raise the trolley 2 are provided on the side of the inverted L-shaped weir plate 4 and one on the opposite side. Further, a U-shaped angle 10 for reinforcing the bogie 2 is fixed to the inner lower surface of the wheel 1 on the side of the inverted L-shaped weir plate 4 of the bogie 2 as necessary.

As shown in FIG. 2, the inverted L-shaped weir plate 4 has a front weir plate 11, a central weir plate 12, and a gradually changing thickness.
The rear dam plate 13 includes a steel plate member and a finished rubber plate 14, and the boundary between the front dam plate 11 and the central dam plate 12, and the boundary between the central dam plate 12 and the rear dam plate 13 are moving in the direction of travel from the lower end to the upper end. Along with inclining to the rear side, the inclination angle of the front side in the traveling direction, that is, the boundary portion between the front weir plate 11 and the central weir plate 12 is reduced with respect to the rear in the traveling direction, and the rear side in the traveling direction, that is, the central weir plate 12 An inclined step portion 15 is formed in which the inclination angle of the boundary portion with the rear weir plate 13 is increased with respect to the rear in the traveling direction. In addition, the front end of the front weir plate 11 is expanded to make it easier to pour concrete.

[0008] Next, the procedure for sealing concrete on the slope using the movable seal mold of the present invention will be described. As shown in FIG. First, as shown in FIG. 1, the width of the wheel 1 of the bogie 2 is adjusted so that the inverted L-shaped weir plate 4 is positioned on the flat surface of the slope 16 where the sealing concrete 17 is formed on the slope 16. The U-shaped rail 18 is laid upward. Then, the wheel 1 of the bogie 2 is placed on the U-shaped rail 18.
Is mounted, and the guide roller 8 is fitted so as to contact the inner side wall of the U-shaped rail 18. Next, the vertical portion of the inverted L-shaped weir plate 4 is rotated about the hinge 3 by rotating the adjusting screw 5 so as to match the slope of the slope 16, and the slope 1 is adjusted.
The inverted L-shaped weir plate 4 is adjusted to the inclination of 6.

The concrete supplied to the front weir plate 11 by the movement of the carriage 2 comes into contact with the central weir plate 12, the rear weir plate 13 and the finished rubber plate 14 in order, but the inclination of the boundary between the front weir plate 11 and the central weir plate 12 is increased. Since the inclination angle of the step portion 15 is slightly inclined with respect to the rear in the traveling direction, the concrete at the lower portion is pushed upward by the inclined step portion 15, and furthermore, the central weir plate 12 and the rear weir plate 13
Since the inclination angle of the inclined step portion 15 at the boundary portion is greatly inclined with respect to the rear in the traveling direction, the inclined step portion 15 is further pushed upward by the inclined step portion 15, and the central weir plate 12 and the rear weir plate 13 are sequentially Since the thickness is increased, the concrete is pressed and smoothed. in this way,
The concrete is sequentially collected by the front weir 11, the concrete is pushed upward by the inclined step 15 at the boundary between the front weir 11 and the central weir 12, and the concrete is crushed and smoothed by the central weir 12. Concrete is further pushed upward at the inclined step 15 at the boundary between the central weir plate 12 and the rear weir plate 13, and the concrete is further crushed and smoothed by the rear weir plate 13, and the finished concrete surface is finished with the finished rubber plate 14. To the final finish.

As described above, concrete is transferred to the front weir plate 11.
