Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a tool that mechanizes and highly efficiently excavates and shapes drainage ditches provided on both sides or one side of a road.

(Prior Art) Conventionally, when excavating a drainage ditch for a road, the excavation was carried out using a box hoe or by hand, and then corrected using a ruler and then finished. However, this method was inefficient, and even with the use of a boxhoe, it was only possible to cover several tens of meters per day, and by hand, it was only a few dozen meters per day.

(Problems that the invention attempts to solve) Therefore, this invention is a tool that attempts to completely mechanize the excavation and forming of road drainage ditches and perform the construction with extremely high efficiency.

(Means for Solving the Problems) An embodiment of the present invention will be described below based on the drawings. Sled stands 1 and 2 formed in a boat shape with front and rear symmetry are arranged parallel to each other on the left and right, and their central portions are connected to a cross beam. 3
A protrusion 4 is protruded from the front and back of the upper surface of the cross beam 3, and an excavated soil removal plate 5 formed in the cross-sectional shape of a road drainage ditch EV is protruded and fixed at the bottom, and a finishing template is also provided. 6, which is mounted parallel to the rear part of the cross beam 3 in the direction of movement and can be attached or detached at will. In the drawings, 7 is a mudguard plate and 8 is a wire hook.

(Usage or Function) As shown in Fig. 4, first place the road drainage ditch forming tool of the present invention configured as described above on a sled base in the direction in which drainage ditch EV excavation is planned, with the finishing template 6 on the rear side. 1,
2, and place the Batsukuho in the forward direction of movement. Then, by backhoe, sled stands 1 and 2 were installed.
Roughly digging the soil between the gaps, then hooking the claws of the batskuhoe to the protrusion 4 of the cross beam 3 and pulling it forward, the excavated soil plate 5 provided at the bottom of the cross beam 3 will cut the cross section into the drainage ditch EV. A V-shaped groove is excavated, and then a V-shaped groove with a regular cross section is compacted and molded by the weight of the main body by a finishing template 6 attached at the rear. In this way, the above-mentioned work is repeated to complete the drainage ditch forming work.

Normally, this work involves excavating in a downward direction according to the slope of the road, so if the cross-sectional shape of the drainage ditch is different on the outside and inside, and the direction of progress is different on the same side, use a finishing mold. The plate 6 is attached to the rear position of the excavated soil removal plate 5 in the direction of travel. When it is necessary to change the direction of the molding tool, the tool is hung from a backhoe or a crane by hooking a wire to the wire hook 8 and changing the direction from front to back.

(Effect of the invention) As described above, the road drainage ditch forming tool of the present invention, together with the use of a backhoe, can complete the excavation and forming work of road drainage ditches with extremely high efficiency. At a distance of 500 to 600 meters, it is approximately ten times more effective than the conventional backhoe and manual molding methods.

In addition, if the present invention is used in combination with the road drainage ditch concreting machine, which was filed at the same time as the present patent application, it is possible to complete concrete-casting drainage ditch construction with high efficiency. By changing the earth removal plate 5 and template 6, it is also possible to excavate and form drainage ditches of various cross-sectional shapes.
