Accordingly, it is possible to build an emergency agricultural water source at the time of water harvesting, and it is expected that the flood can be removed quickly, thereby reducing the flood damage.

However, according to the above-mentioned patent, since the structure of maintaining a constant flow path cross section is based on a general construction method, the smoothness of drainage during flooding is reduced, and sufficient flow path is secured when applied to a farmland between farmland and farmland. It is difficult or has been accompanied by a shrinkage of arable land.

An object of the present invention for improving the above conventional problems, arable land drainage conduits and agricultural waterways using the same to contribute to productivity improvement while reducing the flood damage by maintaining a constant level of arable land in the trend of severe weather changes To provide a construction method.

In order to achieve the above object, one side of the present invention, the tubular body is formed in a structure in which the flow path cross-sectional area is increased from the beginning to the distal end portion, the support plate extends on one side; And water passing means installed to absorb water on at least one surface of the tubular body.

In addition, according to the present invention, the tubular body is selected from the first structure for coupling the cover divided into a plurality of on the open top body or the second structure for coupling the body divided into a flange of at least two sides. It is done.

In addition, according to the present invention, the water supply means is characterized in that it comprises at least one of a filter medium or a water passage.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to one aspect of the invention, it is related to the pipe for drainage of the arable land 10 for paddy farming, but is not necessarily limited thereto. Neighboring arable land (10) and arable land (10) is divided into turf (21), on the turf 21 to install a farm waterway (22) using a tubular body. Even if the farm road 20 including the turf 21 and the farm channel 22 is formed, a sufficient space for the movement of people or goods can be secured.

The tubular body 30 of the present invention is formed in a structure in which the passage cross-sectional area increases from the start portion 31 to the distal end portion 32 and the support plate 33 extends on one side. The starting part 31 means the upstream end and the end part 32 means the downstream end. Increasing the cross-sectional area of the flow path at the downstream end than the upstream end of the tubular body 30 is advantageous in terms of drainage smoothness during flooding. The support plate 33 is formed to have the same height as the stack 21, but in some cases, the stack 21 may be omitted and the one side of the farmland 10 may be formed by the support plate 33. The tubular body 30 may be formed to include a circular cross section or at least partly a curved surface although the rectangular cross section is fine in configuration including the support plate 33.

As an example of the design, referring to Figures 2 and 3, when the length of the tubular body 30 is 400m, the start portion 31 is horizontal (W1), vertical (height) 1m each and the distal end 32 is horizontal (W2) and length (height) can also be set to 2.5 m and 1 m, respectively. Of course, the tubular body 30 is preferably formed of a reinforced concrete structure.

According to such a structure, even if the flow rate increases from the start portion 31 to the end portion 32 during flooding, the drainage is smooth, and only the foreign matter at the inlet of the start portion 31 of the tubular body 30 is smoothly drained. Easy to manage state

At this time, the tubular body 30 has a first structure for coupling the cover 35 divided into a plurality of on the upper body is opened or a second structure for coupling the body divided into a plurality of flanges 36 of at least two sides Choose from The first structure of FIG. 4 (a) illustrates the installation of formwork on the waterway 22, forming a three-sided body including the bottom and both sides, and then sequentially joining the divided cover 35. The second structure of FIG. 4 (b) illustrates the formation of each body divided in a separate place, and then moving to the water channel 22 to combine. In the former case, it is preferable to have a locking groove on the bottom surface so that the cover 35 does not leave at random, and in the latter case, it is preferable to couple through at least two flanges 36 on both sides. The flange 36 may be formed on the bottom surface in addition to both sides as supporting the position shift between the neighboring bodies, but the top surface is omitted because it interferes with the passage.

As a detailed configuration of the present invention, in any case of the first structure or the second structure, the upper surface of the tubular body 30 may extend to protrude more than the body (horizontal, vertical). In the case of the first structure of FIG. 4A, the size of the cover 35 is increased. Since the width (W1) (W2) corresponding to the width of the tubular body 30 of the present invention is a variable structure, if a pair of opposite to be installed inevitably a side space is formed in the middle. If the upper surface of the tubular body 30 is extended to exclude the opposite side spaces, there is no outflow of buried soil and the top surface is flat, so that smooth passage of people and materials is normally ensured.

As a detailed configuration of the present invention, a plurality of drain holes 34 are formed on the support plate 33 in either of the first structure or the second structure. Drain hole 34 is to maintain the water level of the arable land 10 at the time of flooding, if there is a tuft 21 between the arable land 10, the drain pipe 24 is installed in the tuft 21 and coincides with the drainage position You have to. In any case, it is preferable that the drain hole 34 is configured to maintain a constant diameter and open and close as necessary. The size of the drain hole 34 is in the range of 20 to 30 cm according to the size of the arable land 10 based on the circular cross section.

In addition, according to the present invention has a structure that the water supply means 40 is installed to absorb water on at least one surface of the tubular body 30. Water overflowed from the arable land 10 during the flood flows to the upper surface of the start portion 31 of the tubular body 30, of course, but the water supply means 40 is required to partially induce the drainage to the tubular body 30.

At this time, the water supply means 40 is provided with at least one of the filter body 42 or the water passage groove (44). The filter body 42 is a grating type to allow the rebar to be exposed to a portion of the reinforced concrete tube 30, and has a removable structure. Thereby, when the filter body 42 is opened, the inside of the pipe body 30 can be cleaned. Passage groove 44 may be formed by densely forming a plurality of small holes of 1 cm or less in diameter, or may form long grooves having a narrow width and a long length at regular intervals. When the water supply means 40 is installed on the upper surface of the tubular body 30, it may be normally closed by using a separate cover (not shown) and may be opened only during flooding.

According to another aspect of the present invention, it relates to a method for constructing the agricultural waterway 22 having the tuft 21 between the arable land 10 by using the tube 30 described above. More specifically, a method of constructing the agricultural waterway 22 that allows drainage and passage using the tubular body 30 on the farm road 20 that divides the neighboring arable land 10 is provided.

In the first step of the present invention to excavate the center of the tuft 21 to form a waterway 22 to be lower than the arable land (10). The farm channel 22 is easy to excavate the center of the turf 21, but it is also possible to excavate the entire turf 21 depending on the situation of the site. The excavation depth of the farm channel 22 is kept lower than the farmland 10 so that the water in the farmland 10 is smoothly drained to the farm channel 22 side during the flood.

In the second step of the present invention, the tubular body 30 is placed on the agricultural channel 22 and at least the space of the side is buried. Of course, according to the first structure of FIG. 4 (a) or the second structure of FIG. 4 (b), the installation method of the tubular body 30 is somewhat different. In any case, the tubular body 30 is accommodated on the water channel 22 so that the two face each other, and the side spaces formed in the middle of the tube 30 are filled with earth and sand. If rain (soil) is expected to flow in the rain, the upper surface of the tubular body 30 should not be buried. The upper surface of the tubular body 30 should be kept flat to facilitate the passage of people and materials.

At this time, in the first step and the second step, the tubular body 30 is installed such that the depth H2 of the distal end portion 32 is increased than the depth H1 of the start portion 31. The lowering of the depth H1 (H2) of the tubular body 30 is for the purpose of smoothly discharging the water introduced into the start portion 31 to the distal end portion 32. The height of the tubular body 30 is preferably kept the same according to the length, but if the height is different, it may be reflected in the determination of the embedding depth (H1) (H2). The center line passing through the flow path cross-sectional area of the tubular body 30 is kept lower than the arable land 10 over the entire length of the tubular body 30.

As an example of design, referring to FIG. 3, when the length of the tubular body 30 is 400 m, the depth H1 of the start part 31 may be 10 cm and the depth H2 of the distal end 32 may be 1 m. have. Of course, the height of the support plate 33 must be changed in an interlocked manner so that the height of the stack 21 can be constantly adjusted.

In the third step of the present invention, the drain pipe 24 for adjusting the water level of the arable land 10 is installed in the stack 21. Drain pipe 24 formed in the stack 21 is to match the respective positions of the drain hole 34 formed in the support plate 33 of the tubular body (30). Accordingly, when the water level of the arable land 10 during flooding is increased, the water is drained to the upper surface of the tubular body 30 through the drain pipe 24 and the drain hole 34 and drained into the tubular body 30 through the water supply means 40. do.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
