[Industrial applications]

 The present invention relates to a concrete shunt rectangular basin used at a diversion intersection of an open drainage channel, an open drainage channel or an open drainage channel, and an underdrain drainage channel used for infrastructure improvement work in an agricultural field. It is a thing.

[0002]

[Prior art]

 Although not shown in the figure, conventional shunt intersections of waterways include shunt intersections for cast-in-place concrete, cylindrical shunt intersections with fume pipes, and combinations of waterways with openings in precast stiles. It was

However, these products have the following drawbacks and problems.

[0004] For cast-in-place concrete, after constructing an open drainage channel (usually a bench flume or drainage flume) and an underdrain drainage channel (usually a fume pipe or an envipipe), wrap them, formwork assembly, It requires a lot of time and labor because it involves the steps of rebar assembly, concrete pouring, curing, mold removal, and surface finishing.In particular, these constructions are performed during rainy seasons after harvesting rice and during rain and snow. Since the work is done on farmland, there was a drawback that mud adhered to the formwork and reinforcing bars depending on the weather, resulting in variations in the quality of the finished product.

Cylindrical shunt crossing work using fume pipes is easy to construct and relatively inexpensive, but due to the clogging of debris from open canals, this method has too many complaints from farmers, and There were major issues in countermeasures and maintenance.

[0006] Similarly to the precast square tubs, which are most widely used at present, when one side wall is drainage for underdrain, clogging of dust occurs and at the same time, an air hammer phenomenon (drop water flow wave) in the drainage channel occurs. Due to the fact that air enters and is compressed due to the impact), at the same time, in any of the construction methods, small animals that live in the field fell into this open waterway, gathered, and became a graveyard. There was no consideration for that. Therefore, the applicant of the present invention has settled the following problems to be solved by the product of the present invention while engaging in the manufacture and construction of these products.

[0007]

[Problem to be Solved by the Invention] A product having a structure in which an elevating means is constructed that can help small animals inhabiting the field that flow down to an open waterway and gather here, and at the same time, a product that can be elevated and lowered by maintenance personnel.

[0008] In the case of the open channel to the underdrain, the static water pond construction product is so constructed that the water entering the underdrain drainage does not cause an air hammer phenomenon.

A product is constructed that is easy to construct and maintain.

It is ensured that the dark beam drainage function does not deteriorate due to clogging of dust.

[0011] In addition, in the fish and shellfish habitat, consideration should be given so that an opening can be provided in the lower part of the side wall if necessary, and a fish bed part can be constructed below the back embankment of the side wall. Based on the above problems, the solution means of the present invention is as follows.

[0012]

[Means to be solved by the device]

 In the case of the drainage channel for opening to the drainage channel for opening, the basin should be rectangular, and a drainage channel for one open should be provided along with a step for raising and lowering humans. Can be installed (non-slip unevenness that can climb up).

[0013] In the drainage for open drainage from the open drainage, a screen that allows a human to ascend and descend in the center and a small animal to ascend (crawler) on the side is slantably fitted. This will be sequentially described with reference to the embodiment drawings.

[0014]

[Example of device]

 First of all, in the case of the diversion basin from the open drainage channel to the open drainage channel, Fig. 1. (This example is an example of flowing from one side to the other side, but there is a two-way split on one side, a two-way split, a two-way split on one side, etc.). And one side wall 1-1. Open water channel B-1. And the slanting lifting block D-1. An opening with a width that can be installed together with.

The other side wall 2-1. Is the drainage channel B-2. The inner surface height (depth) of the product is at least 20 to 30 cm higher than the deep inner bottom surface. The height of the still water pond that doubles as a mud pool 3. (See FIG. 4 and FIG. 6).

At this time, the tilting lifting blocks D-1. Is an elevating step that allows humans to ascend and descend between the side walls. 4. Considering earth pressure resistance as a separator step that takes into consideration the earth pressure on the side wall, the inside surface of which can be moved up and down by small animals that live in the field. (Usually, a net or sand mat may be attached, or the inner surface may be concrete mixed with wood chips, or a rough surface product with cut gravel may be used.).

This is shown in FIG. As shown in the concrete rectangular box A. Open waterway B-1. , Shunt open B-2. And its voids in concrete mortar 9. Will be assembled and assembled.

Next, the case of drainage for underdrain from the drainage channel for opening is described in Example 2. And Figure 4. This will be described with reference to FIG.

The main body of the sluice is a concrete rectangular sluice A. And one side wall 1-1. Open drainage channel B-1. Provide a hole that can be installed. The other side wall 1-2. Is a still water reservoir that doubles as a mud pool. Height of H. (Refer to FIG. 4 and FIG. 5). Circular opening 2-2. To provide.

After assembling these, the side wall 1-2. From the top of, the bottom plate 4. 8. A means for raising and lowering small animals to the side by inclining from the center (screen fitting recess 7.). (Sandmat is acceptable if it is a net, but it can be easily moved up and down by small animals if it is water-permeable and does not corrode.) Steel-controlled dust stop lifting screen D-2. It is a concrete shunting sluice in which one is used as an open drainage channel and the other is used as an underdrain drainage channel. Such a product of the present invention has the following actions and effects.

[0021]

[Advantage and effect of the device] In the present invention, the shunt basin used to be the graveyard of small animals (locusts, crickets, worms, frogs, etc.) that live in the numerous fields that fell into the open drainage canal is Since the structure is such that animals can be raised and lowered, it can be said that it is a naturally friendly product that takes into consideration the natural environment and the ecosystem, and because it is a structure that allows humans to easily ascend and descend, it is easy to maintain and manage in the basin. There is.

Even in the case of drainage for an underdrain from an open drainage channel, since water flows through the dust collected on the screen, there is no water wave before entering the underdrain drainage port, and the inside of the closed underdrain drainage channel is closed. Then, the air hammer phenomenon due to the air pressure unlike the conventional case does not occur.

In addition, the screen is full of basins, and the inner surface of the slope is a void with a width (construction of a large static water reservoir), and the quiet water that has penetrated the dust here easily flows to the drainage port for the underdrain, and Does not lower the drainage function.

In case of mud raising, which is a management problem from the open drainage channel to the underdrain drainage channel, the screen was fitted in the recess of the bottom slab (Fig. 4. Fig. 6) and the side wall leaned to the center. Mud G-1. When you have finished lifting, lay it on the opposite side wall without removing the screen, then mud G-2. And raise the screen to the side wall 1-2. Since the work is completed by returning it to, it is comparable to the conventional mud lifting work and there is no difficulty because it is easy to move up and down.

In addition, the hydrostatic height H. Considering the fish floor E. By arranging under the embankment outside the side wall, the diversion basin of the present invention can provide not only small terrestrial animals inhabiting the field but also a habitat for aquatic small animals.
