BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is laid on a soft ground such as an unpaved agricultural road, a shore, or a path in a flower bed, so that people and agricultural machinery and equipment can easily move on the soft ground. More particularly, the present invention relates to a connecting sole plate used by connecting a plurality of members in a predetermined shape.

[0002]

2. Description of the Related Art For example, it is not usually practiced to pave a shore which divides one field from another farm road. Because of this, the shore is soft and easily collapses when entering and exiting agricultural machinery such as tractors and rice transplanters with the rice field, making the entry and exit work extremely difficult. This is also true for unpaved farm roads.

[0003] On the other hand, roads in fields and flower beds are not specifically paved, so that, for example, when people get wet in the morning soup or after raining, people pass through the roads. When trying to do so, the soil sticks to the shoes and is difficult to walk. Also, this road may be broken by walking, but the roots of vegetables and flowers may be growing in the soil under the road in the fields and flower beds,
It is of course not a good thing for the road to collapse due to weakness.

[0004] The above-mentioned problems do not occur if the roads in the flowerbed and the shore of the rice field are paved, but paving these soft grounds is as follows. Not done for a reason. In other words, apart from the shores of the fields, the paths in the fields and flower beds can be changed every year depending on the plants to be made, and as mentioned above, they are also the places where the roots of the plants grow, These roads cannot be paved and made permanent.

[0005] On the other hand, when it comes to the agricultural road, there are some parts that are paved, but the pavement is not applied to the boundary with the rice field, that is, the part where agricultural machinery enters and exits. Is hardly paved. This is because the portion of agricultural machinery that enters and exits the field only needs to be small enough for the machine to pass through, and that portion varies with seasons and crops.

Therefore, the present inventor has examined whether there is a technique for easily paving a soft ground as described above, but has not found any suitable technique. For this reason, the applicant has examined whether the curved drainage slope member member already proposed in Japanese Patent Application No. 7-321777 or the like can be used. Unlike the standardized drainage ditch,
They have various shapes, sizes, and inclinations, and thought that they could not be applied as they were, and completed the present invention.

[0007]

The present invention has been made on the basis of the above circumstances, and the problem to be solved is to make it possible to easily harden a soft land such as an agricultural road. is there.

That is, an object of the first aspect of the present invention is to make it possible for agricultural machines and people to pass over a soft land with confidence regardless of the shape and inclination of the soft land. Leveling can be done, the shape to be leveled can be changed freely, and it can be easily put together when not in use .
