DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiment of the present invention will be described with reference to the drawings showing an example in the case of a V-shaped concrete drainage ditch having a generally gently inclined groove wall. As shown in FIG. 1, a bucket A for construction provided with a V-shaped plow 1 having a gentle slope, and a plate 2 formed in a V-shape with a gentle slope and extending to both left and right sides. And a bucket B for construction provided with a concrete input hopper 3 above. The bucket A is horizontally moved while being dug down from the soil surface to dig a V-shaped groove on the floor. The concrete is put into the input hopper 3 while being moved while keeping a gap corresponding to the concrete casting thickness with the floor excavated groove, and poured into the gap to be cast.

The bucket A is formed by bending a plate in a V-shape from a steel plate or the like, cutting the front portion obliquely to sharpen the tip 1a, and providing a back plate 1b at the rear end to form a V-shaped plow 1. The bending angle W is bent in a V-shape with a gentle slope of about 90 to 150 degrees. In addition,
The bending angle W is a case of a V-shaped drain groove having a gentle slope, and the present invention is not limited to this because the present invention is similarly applied to a case of a V-shape where the slope is not gentle. Absent.

Further, the V-shaped upper end 1c bent in the V-shape,
1c, the plate is horizontally extended on both left and right sides, and the extended end is bent upward at a right angle to form bent edges 1d, 1d according to the thickness of the concrete cast, and the upper end surface of the back plate 1b It is formed flush.

The back plate 1b of the bucket A constructed as described above is attached by welding or the like to a bracket 4 to be attached to the tip of the arm of the backhoe. The bracket has a connection hole at the tip of the arm of the backhoe. Connection holes 4a, 4a for connection with a connection rod are formed in accordance with the above. The inside of the upper end portion of the back plate 1b is reinforced with a reinforcing rod 5.

The bucket B is bent in a V shape by a steel plate or the like, and the front part 2a and the rear part 2b of the plate are left above the plate 2 extending horizontally to the left and right and the rear side of the upper end of the V shape. And concrete input hopper 3 is provided,
As shown in FIG. 2, the plates 3A and 3A extend obliquely downward and rightward from above the center of the input port hopper, and are joined to the joints 2c and 2c with the upper ends of the grooves formed by bending in the V-shape. Wall plates 3B of the inlet hopper 3 , inner wall portions 3b of the 3B,
3b, holes 3a, 3a are drilled, and concrete put into the input hopper 3 is a plate 3A, 3A.
Flow down the inclined surface and flow into the groove dug from the holes 3a and 3a. Bending angle W1 for bending into V-shape
Is bent so as to match the bending angle W of the bucket A, and the bent V-shaped upper end is reinforced by a reinforcing rod 6.

On the lower surface of the plate extending horizontally on the left and right sides of the upper end of the V-shape, guide plates 3C, 3C having a height corresponding to the concrete casting thickness are provided on the wall plate of the inlet hopper 3. 3B and 3B are integrated and stand in parallel,
On the guide rails laid on both ends of the trench excavated on the floor, lower surfaces 2d outside the guide plates 3C and 3C of the plate 2,
The bucket B is moved by guiding the guide plates 3C and 3C inside the guide rails. An eyebolt 7 is attached to the front for pulling and moving with a wire rope or the like.

The guide plates 3C, 3
Since the outer lower surfaces 2d and 2d are moved while being in contact with and mounted on the guide rails, the frictional resistance due to the contact is large, and the lower surfaces 2d and 2d are preferably pulled and moved by a civil engineering machine such as a backhoe.

FIG. 3 shows a bearing 9 with rollers 8, 8 at the front and rear portions of the plate 2 and outside the guide plates 3C, 3C so that the outer peripheral portion of the rollers protrudes from the lower surface of the plate 2. 9 shows an embodiment of a bucket B which is attached and fixed to both ends of a shaft 10 rotatably supported by the above and mounted on a guide rail so as to be able to roll. it is possible to reduce the movement of B, even without the use of civil engineering and construction machine such as a backhoe can be movable.

[0014] Next, before Symbol bucket A, using a bucket B, describes the construction example of the V-shaped concrete culvert was a gradual sloping surface. First, as shown in FIG. 4, the bucket A is connected to the tip of the arm 11 of the backhoe (not shown), and the bracket 4 attached to the back plate 1b of the bucket A and the tip of the arm 11 of the backhoe are connected to the connecting rod 12. Connect and attach with.

A hydraulic cylinder 13 is mounted on the arm 11 of the backhoe, and the bucket A can be leveled or raised by operating an operating rod 13A of the hydraulic cylinder 13. Then, the bucket A is erected, the sharp tip 1a is cut into the soil surface, the bucket A is kept horizontal while being dug down, and the backhoe is retracted, so that the V-shaped groove 14 having a gently sloped groove wall is formed. Dig the floor.

The V-shaped groove 14 formed by excavating the floor
Is a gently inclined surface of the bucket A and is bent V
The cross section of the floor excavation is gently inclined as shown in FIG. 5 by the bent edges 1d and 1d formed by extending the plate to the right and left sides of the V-shaped upper end and the V-shaped upper end and bending the ends upward at right angles. V-shaped groove 14a, and horizontal recessed steps 14b, 14b recessed from the soil surface on both sides of the upper surface of the groove 14a. I have to be one.

[0017] Then, before Kiyukaho the V-shaped groove 14 of the recessed step portion 14b, the left and right corners of 14b, sleepers 16 wear resistance good guide rails 15 and 15 as shown in FIG. 6,
16 are laid on the upper surfaces of the laid guide rails, and outer lower surfaces 2d and 2d of the guide plates 3C and 3C of the plate 2 bent in a V-shape of the bucket B and extended in parallel to the left and right are provided on the upper surfaces of the laid guide rails. V
A gap S corresponding to the concrete casting thickness is maintained between the V-shaped groove 14 and the lower surface of the plate 2 bent in the V-shape and extended in the left-right direction.

With the bucket B mounted on the guide rail as described above, a wire rope is hung on the eyebolt 7 (FIG. 1) attached to the bucket B, and the bucket is pulled and moved by civil construction such as a backhoe. The concrete 17 is introduced into the B inlet hopper 3.

The concrete 17 introduced into the inlet hopper 3 flows down the inclined surfaces of the plates 3A, 3A extending obliquely downward from above the center of the bucket B, and the holes 3a, 3a.
a into the gap S from above a, and the bucket B moves, so that the rear portion 2b of the plate 2 of the bucket B moves.
(Fig. 1) Finished to stroke the concrete surface with the lower surface, and even if the concrete surface has uneven finish,
Since a uniform casting thickness is maintained and finished, it is only necessary to lightly stroke the surface with a trowel, and the uniformity is not impaired.

As shown in FIG. 7, a roller 8 is attached to the lower surfaces 2d and 2d of the plate 2 which is bent in a V-shape of the bucket B and extends parallel to the left and right.
Is mounted on a shaft 10 rotatably supported by a bearing 9 and is rolled on a guide rail 15 to reduce the movement of the bucket B, and to be used as a civil engineering and construction machine such as a backhoe. It is possible to move without pulling. In FIG. 7, a roller 8 having a V-shaped outer periphery is provided. A V-shaped groove is provided in the guide rail 15, and the outer periphery of the roller is fitted in the groove of the guide rail 15 so that the roller 8 can be moved by rolling. Can be prevented from rubbing against the side surfaces of the guide rail 15 and the sleeper 16. However, when the side surface of the guide plate 3 </ b> C is guided against the side surfaces of the guide rail 15 and the sleeper 16, a groove is formed in the guide rail 15. Instead, the outer peripheral portion of the roller may be flat.
