Description

The present invention relates to an agricultural water level adjusting basin to be installed on a paddy ridge.

Generally, in a paddy field, the water level of an adjacent paddy field partitioned by ridges is changed so that water is supplied sequentially from an upstream paddy field to a downstream paddy field. In conventional water level adjustment, a part of the ridge is cut to form a drain, and a drain of an appropriate height is sandwiched in this drain, so that the water overflowing from the upper part of this plate flows to the downstream paddy field. Has become.

However, when heavy rainfall caused a large amount of water to flow into the drainage ditches that were cut into ridges and the drainage ditches collapsed, there was a problem that the board fell and water flowed out, making it impossible to adjust the water level. In addition, since a drain is formed by cutting a part of the ridge, there is also a problem that the vehicle cannot run when walking on the ridge or transporting by a unicycle.

The present invention solves the above-mentioned problems, and ensures that the water level can be adjusted.Moreover, the ridges are not cut, so that walking and unicycles can be run on the ridges. To provide.

The water level adjusting basin for agricultural use according to claim 1 of the present invention is provided with a plastic cylindrical socket for connecting a drainage pipe to a lower part of a front wall of a box-shaped concrete body having an open upper surface and a rear surface. A mounting groove for detachably mounting a concrete water level adjusting plate set at the water level in the vertical direction is formed on the rear side of the left and right side walls of the concrete body, and an unused water level adjusting plate is horizontally held. The retaining groove is formed on the upper side of the front wall and the left and right side walls of the concrete body.

The agricultural water level adjusting basin according to claim 2 of the present invention is characterized in that the water level adjusting plate is constituted by a plurality of sets having different heights.

According to the agricultural water level adjusting basin according to claim 1 of the present invention, a water level adjusting plate having an arbitrary height is attached to the back opening of the box-shaped concrete body, and the water level of the paddy field rises to increase the water level adjusting plate. When the water reaches the height of the paddy field, the water overflows from here, flows into the concrete body through the upper side of the rear opening, and is drained from the cylindrical socket to the irrigation canal through the drain pipe. The water level can be constantly adjusted.

If you want to change the water level, replace another water level adjustment plate with a mounting groove and fit the removed water level adjustment plate into the holding groove formed on the upper side of the concrete body, and Since it is held horizontally, loss can be prevented. Further, the other water level adjusting plate is held at the same height as the height of the ridge, so that it is possible to walk on this and a unicycle can run, and thus the workability is excellent. Further, since the concrete body and the water level adjusting plate are made of concrete, they can be manufactured with high strength, excellent durability and at low cost.

According to the agricultural water level adjusting basin of the second aspect, since the water level adjusting plate is composed of a plurality of sets having different heights, the water level can be adjusted to an arbitrary level.

A water level adjustment basin for agricultural use that adjusts the water level in paddy fields has been realized.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. As shown in FIGS. 1 and 2, reference numeral 1 denotes an agricultural water level adjusting basin, which is formed of a box-shaped concrete body 1 having an open upper surface and a rear surface. A plastic cylindrical socket 4 such as a tube penetrates and is integrally attached. On the rear side of the left and right side walls 5 and 6 of the concrete body 1, mounting grooves 7, 7 having a U-shape are formed in the vertical direction, respectively. Further, L-shaped holding grooves 8, 8 are formed on the upper surface sides of the left and right side walls 5, 6 of the concrete body 1, respectively, and the distance between the opposing surfaces thereof is formed to be the same as the distance between the mounting grooves 7, 7. .

Also, 9A shown in FIG. 3 is a concrete water level adjusting plate whose height is formed slightly lower than the rear opening 11 of the concrete body 1 and whose width is formed to oppose the left and right side walls 5 and 6. It is formed slightly shorter than the interval between the two mounting grooves 7, 7, and the plate thickness is formed slightly smaller than the inner width of the mounting groove 7. 9B is also a concrete water level adjusting plate, which is lower in height than the concrete water level adjusting plate 9A, and has the same width and plate thickness.

In the agricultural water level adjusting basin having the above configuration, for example, as shown in FIG. 5, a part of the ridge 14 between the paddy field 13 and the irrigation channel 16 is cut off, and the upper part of the agricultural water level adjusting basin 1 and the ridge 14 are at the same height. Install so that it becomes. A drain pipe 15 is connected to the cylindrical socket 4 so as to communicate with the irrigation channel 16, and is buried under the ridge 14. Thereafter, as shown in FIG. 4, both ends of the water level adjusting plate 9A are inserted from above the mounting grooves 7, 7 and mounted. When the unused water level adjusting plate 9B is horizontal and fitted into the holding grooves 8, 8 formed on the upper side of the box-shaped concrete body 2, the upper surface becomes horizontal with the ridge 14.

In this state, when the water 17 is drawn in from an adjacent paddy field (not shown), the water level of the paddy field 13 rises. When the water level reaches the height of the water level adjusting plate 9A, the overflowing water 17 flows into the box-shaped concrete body 2 through the back opening 11 and further to the cylinder attached to the lower side of the front wall 3 The water is drained from the socket 4 to the irrigation channel 16 through the drain pipe 15, and the water level in the paddy field 13 is kept constant.

When it is desired to lower the water level, the water level adjusting plate 9A is removed from the mounting grooves 7, 7 and replaced with a lower water level adjusting plate 9B, and the removed water level adjusting plate 9A is placed on the upper part of the box-shaped concrete body 2. It is held horizontally by being fitted into holding grooves 8 formed on the side.

Therefore, one of the water level adjusting plates 9A, 9B is attached to the attachment grooves 7, 7 and the other not used is retained in the holding grooves 8, 8 for storage, thereby preventing loss. The other unused water level adjusting plate 9B is held horizontally so as to be at the same height as the ridge 14, as shown in FIG. Excellent in nature. In addition, since the box-shaped concrete body 2 and the water level adjusting plates 9A and 9B are made of concrete, they can be manufactured with high strength, excellent durability and at low cost.

In the above description, the case where two sets of water level adjusting plates 9A and 9B having different heights are used is shown. However, three sets of low water level adjusting plates 9B may be used. The water level adjusting plates 9B, 9B may be mounted in the mounting grooves 7, 7.

In the above description, the case where the water level of the paddy field is adjusted has been described. However, an agricultural water level adjusting basin may be provided on the irrigation channel side of the ridge to draw water from the irrigation channel into the paddy field.

FIG. 3 is a perspective view of the agricultural water level adjusting basin according to the embodiment of the present invention as viewed from the front side. It is the perspective view which looked at the agricultural water level adjustment basin of FIG. 1 from the back side. It is a perspective view which shows a water level adjustment plate. It is a perspective view which shows the state which attached the water level adjustment plate to the agricultural water level adjustment basin of FIG. FIG. 2 is a cross-sectional view showing a state where the water level adjusting basin for agricultural use of FIG.
