Description

[Detailed explanation of the invention] This invention is particularly suited to the surplus water (groundwater, surface seepage water, spring water, etc.) in wetlands such as wetlands.

) This relates to a waterway for taking in and draining water, and provides a structure for a waterway for wet fields that has an integral structure with excellent compressive stress, regardless of whether it is made of concrete.

Traditionally, in land improvement in wetlands such as wetlands, a method of draining excess water has been to bury perforated pipes made of vinyl chloride, etc., with water intake holes underground. Even if holes were laid with stones, etc. around the pipes during construction, they would become clogged with water scale, sediment, etc. in a short period of time, resulting in almost no water intake capacity.

Moreover, once buried, it may not be possible to recover the function of the perforated pipe even if its function deteriorates.

The object of the present invention is to provide a waterway for wet fields etc. which can eliminate the above-mentioned conventional drawbacks.

Next, an embodiment of the present invention will be described with reference to the drawings.

The supporting material for constructing the waterway in this example consists of a bottom part 1, left and right side parts 2,
2 and the upper part 3 are integrally molded with concrete into a substantially frame shape, and this space-like window becomes a water passage part 4 through which water passes.

The size of this water passage portion 4 is determined by the effective width and depth of the water channel T.

Therefore, while the shoring material of this example is molded from concrete material for supporting the panel 6, the panel 6 is molded from concrete material into a rectangular flat plate shape, and when constructing the waterway T, the panels 6 are formed in multiple stages. By constructing both side walls of the water channel, both sides of the water channel are supported, and an elongated gap is provided along the lower side of the panel 6 as shown in the figure to provide water passage through the side wall. This is the water elongated hole 6a.

Subsequently, the functions and effects of the embodiment configured as described above will be explained.

First, to give an overview of the construction of a waterway using shoring materials in this example, the earth and sand are removed from the area where the waterway T is to be constructed, a trench is created, and a large number of shoring materials are placed at equal intervals within this trench. At the same time, several panels 6 (three panels are shown in the figure) are stacked along the left and right sides 2, 2 of each shoring material on their long sides, and then the side walls made of each panel 6 are stacked. Sediment is applied to the outside, and each panel 6 is pressed against each side portion 2 by the earth pressure of the earth and sand to form a waterway T (see Fig. 3).

In this way, the wetland waterway T is constructed to take in and drain excess water around the waterway T from the water passage slots 6a in the bottom and side walls of the waterway T, so large earth pressure is applied to the supporting materials such as wetland fields. Even in the case of a waterway T, the rigidity of the frame-shaped supporting material is increased, making it possible to construct a waterway T with excellent durability.

Next, to explain the waterway T1 shown in FIG. 4 as another example, a waterway T□ is constructed on the left and right side edges of two rice fields W separated by a ridge R in the center of the drawing, and The surplus water of rice field W is taken out and discharged through the waterway T1 on the left side of the figure, and the surplus water of the rice field W on the right side of the figure is taken out and discharged through the waterway T1 on the right side of the figure. When the upper surface of T1 is covered with a separate lid panel 6b, a ridge can be formed on this lid panel 6b.

In other words, the present invention has excellent strength due to the configuration described in the claims, can take in and drain excess water especially in wet fields, and can be easily constructed even in weak farmland. The unique structure of the present invention has the unique feature that it is easy to construct a waterway according to the design.

Note that the supporting material of the present invention may be formed from a material such as resin concrete.
