A space (S1) is located inside the dug part (1). Although the drawing shows a space S1 according to the first embodiment of a relatively large lot, spaces S2 and S3 according to other lots may also be located.

The culvert drain pipe insertion groove 21 by the tractor 10 equipped with the culvert drain pipe burial machine 100 is formed in the space S1 formed inside the excavation part 1 . The insertion groove 21 is formed and the culvert pipe 210 is buried at the same time, so that only the insertion groove 21 cannot be located in the spaces S1, S2, S3, but for explanation, the space before the culvert pipe 210 is buried (S1, S3, S3) is shown.

In addition, a water collecting pipe insertion groove 22 for facilitating the connection of the water collecting pipes 220 and 240 may be further formed.

1) first embodiment

A method of constructing a culvert drain pipe according to the first embodiment will be described with reference to FIGS. 4, 5, and 9 to 11 .

The culvert drainage pipe construction method according to the first embodiment comprises the steps of: (a) the tractor 10 forming a dug part 1 of a preset depth at the edge of the construction space; (b) forming a plurality of installation grooves 21 so that the culvert drain pipe laying machine 100 is spaced apart from each other by a predetermined distance (g1) along one direction in the space s1 formed inside the excavation part 1, and the installation groove ( As a step of burying the culvert pipe 210 in 21) and spraying the rice husk on the buried culvert pipe 210, the depth of the installation groove 21 is the excavation part 1 in the center of the space S1. towards the deeper, step; (c) connecting the central portion of the culvert pipe 210 buried to have a predetermined interval from the lower side, extending in the long side direction of the space S1 and communicating with the culvert pipe 210, a first water collecting pipe 220 is installed step; (c1) the culvert pipe 210 and the first collection pipe ( 220) communicating with each other; (c2) installing a second water collecting pipe 240 on the lower side of the culvert pipes 210 to cross the culvert pipes 210; (c3) installing a water level regulator 260 at one end or the other end of the second water collection pipe 240; (d) installing the second water collecting pipe 240 to extend in the long side direction at one end and the other end of the culvert pipe 210 buried to have a predetermined interval; (e) each end and each other end of the culvert pipe 210 by a plurality of connectors (230, 250) connected to the second water collecting pipe (240), respectively; (f) installing a water level regulator 260 at one end or the other end of the first water collection pipe 220; (g) the step of the tractor 10 backfilling the excavation (1); And (h) the tractor 10 step of subsoil crushing the excavation part (1) and the space (S1); includes.

First, the tractor 10 forms a dug part 1 of a preset depth h1 at the edge of the construction space.

The preset depth h1 of the dug part 1 may be 40 cm to 50 cm.

In the conventional construction method, there was a problem of soil disturbance during subsoil crushing of the excavation part 1 after the construction was completed by digging the excavation part 1 by 2 m or more. When the tractor 10 is used, the excavation part 1 of a small depth is formed, and the problem of soil disturbance does not occur.

Next, a plurality of installation grooves 21 are formed and the installation grooves ( 21), the culvert pipe 210 is buried, and the rice husk is sprayed on the buried culvert pipe 210.

The space S1 is a square space formed by a long side of 100 m and a short side of 100 m, and is a space S1 according to the first embodiment.

Since the space S1 according to the first embodiment is larger than the spaces S2 and S3 of the second embodiment, it is necessary to additionally secure drainage capacity, and a construction method for this will be described later.

The depth of the installation groove 21 is preferably deeper toward the excavation part 1 from the center of the space S1. Accordingly, the culvert pipe 210 buried therein is deeper as it goes from the center of the space S1 toward the excavation part 1, and when described based on the culvert pipe 210, the culvert pipe 210 extending in one direction. Silver has an inclination that decreases from the center of the culvert pipe 210 toward one end and the other end of the culvert pipe 210 .

The slope formed from the center of the culvert pipe 210 toward the end of the culvert pipe 210 may be 1.8 to 2.2%, and may be 2% in a preferred embodiment. Accordingly, the water or nutrient solution of the culvert pipe 210 gathers at the end having the lowest inclination and is rapidly drained.

In addition, the culvert pipe 210 further includes a nonwoven wrapping part 211 surrounding the outside, and has a diameter of 50 mm, and each culvert pipe 210 is buried while being spaced apart from each other at intervals of 3 m to 5 m. In the conventional case, the gap of the culvert pipe is usually formed to be 7m to 10m apart, and thus there is a problem that drainage is not performed smoothly. The construction method according to the present invention can solve this problem by burying the culvert pipe 210 at intervals of 3m to 5m, and moreover, it is possible to drain quickly.

In addition, in the culvert pipe 210, a hole for drainage may be spirally formed along the outer surface of the culvert pipe 210.

On the other hand, the rice husk sprayed on the upper culvert pipe 210 forms a hydrophobic material layer 310 .

The height h2 of the hydrophobic material layer 310 formed by the rice husk may be 20 cm.

Next, the first water collecting pipe 220 is installed so that the culvert pipes 210 communicate with each other at one end and the other end of the culvert pipe 210 buried to have a predetermined interval.

Specifically, by connecting one end and each other end of the culvert pipe 210 to the first water collecting pipe 220 by a plurality of connectors 230 and 250, the culvert pipe 210 and the first collecting pipe 220 these communicate with each other

Water or nutrient solution passes through the first water collecting pipe 220 when irrigated, and since the first water collecting pipe 220 is located at one end and the other end, which are the lower ends of the culvert pipe 210 , respectively, fast drainage is achieved.

The connectors 230 and 250 connected to the culvert pipe 210 located on the inside except for the outermost side in the longitudinal direction may be a 'regular T'-shaped connector 230 .

The connectors 230 and 250 connected to the culvert pipe 210 respectively located at the outermost side in the long side direction may be a 'L'-shaped elbow connector 250 .

Next, the second water collecting pipe 240 is installed on the lower side of the culvert pipes 210 to cross the culvert pipes 210 (see FIG. 5 ).

In the case of a time when water or nutrient solution is supplied excessively, such as during the rainy season, more water is collected and drained through the second collection pipe 240 communicating with the lower center of the plurality of culvert pipes 210 , and at the same time, one end of the culvert pipe 210 is and the first water collecting pipe 220 located at the other end will collect and drain the water. When the water or nutrient solution is in the dry season or at an appropriate water level, gravity is moved to one end and the other end of the culvert pipe 210 by the inclination formed in the culvert pipe 210 , and it will be quickly drained only by the first water collecting pipe 220 .

Next, a water level regulator 260 is installed at one end or the other end of the second water collection pipe 240 , and a drain box 201 connected to the culvert pipe 210 in fluid communication in the construction space is installed.

When soil accumulates inside the culvert pipe 210, the drainage box 201 can wash it. Since the culvert pipes 210 installed by the construction method according to the present invention are connected to each other, when a lot of water is flowed from the drainage box 201 installed in the construction space, it is possible to easily remove the soil and soil, so that the drainage function can be maintained for a long time. can

In another embodiment, the water level regulator 260 may be installed in the plurality of connectors 230 and 250 connecting the first water collecting pipe 220 , and a detailed description will be given in the embodiment to be described later.

In addition, as shown in FIG. 9 , an automatic soil moisture meter 202 and an automatic underground water level meter 203 are installed in the construction space, and the water supply tank 201 can be opened and closed to drain or supply water to the construction space. .

Since the second water collection pipe 240 is further installed in the construction space by the construction method of the first embodiment according to the present invention, it is possible to solve the problem of poor surface drainage in the large-division lot, which is a flat land with little slope. .

Next, the tractor 10 backfills the excavation part (1).

Next, the tractor 10 crushes the subsoil part 1 and the space S1.

Specifically, the tractor 10 crushes the subsoil of the upper part where the excavation part 1 and the culvert pipe 210 are installed.

In the case of the conventional construction method, the excavation part 1 is formed to a depth of about 1 m, and a soil disturbance problem occurs when the subsoil is crushed. In the case of the construction method according to the present invention, the excavation part 1 is formed within 50 cm, Culvert pipes can be buried without significant disturbance. In one embodiment, the subsoil is crushed to the upper part of the excavation part 1, but the culvert pipe 210 and the upper part of the hydrophobic material layer 310 formed from rice husks in the upper part. Accordingly, it can be reused as a paddy field at any time by maintaining the nutrients in the ground and not breaking the level of the ground.

2) second embodiment

A method of constructing a culvert drain pipe according to a second embodiment will be described with reference to FIGS. 2, 6 to 9, and 11 .

In the case of the second embodiment, the land applied to the first embodiment is different, and thus a different construction method is provided. As described above, the lot of the first embodiment has a large section and the lot of the second embodiment has a relatively small section, so there is a difference in that the water collecting pipe is not located further in the center of the culvert pipe 210 .

The second embodiment provides the construction method of the first method and the second method according to the area of the lot. A method of constructing a culvert drain pipe common to the first and second methods will be described first.

Unlike the first embodiment, in the second embodiment, there is a difference in that the culvert pipe 210 is drawn out and buried in the long side direction.

Second Embodiment In the first method, the spaces S2 and S3 are spaces S2 formed by a long side of 100 m and a short side of 50 m.

Second Embodiment In the second method, the spaces S2 and S3 are spaces S3 formed with a long side of 100 m and a short side of 30 m.

That is, in the case of the second embodiment, the construction space compared to the lot of the first embodiment is relatively small, so the second water collecting pipe 240 for facilitating drainage is not required, so only the first water collecting pipe 220 located at both ends will include

At this time, the culvert drain pipe laying machine 100 will withdraw and bury the culvert pipe 210 so as to have an inclination that increases from the entire length of the culvert pipe 210 toward the center, and for this purpose, it is shallower toward the center in the entire length in the long side direction. It will be preceded by the formation of an installation groove that deepens again after being lost.

The slope formed from the center of the culvert pipe 210 toward the end of the culvert pipe 210 is 1.8 to 2.2%, preferably 2%, in the configuration of the culvert pipe 210 as in the first embodiment. A detailed description thereof has been omitted.

Next, the first water collecting pipe 220 is installed in the short side direction so that the culvert pipes 210 communicate with each other at one end and the other end of the culvert pipe 210 buried to have a predetermined interval.

Specifically, by connecting one end and each other end of the culvert pipe 210 to the first water collecting pipe 220 by the plurality of connectors 230 and 250 , the plurality of culvert pipes 210 and the first collecting pipe 220 are in communication with each other.

Next, the water level regulator 260 is installed in any one of the connectors 230 and 250, the drainage box 201 is installed inside the construction space, and the tractor 10 backfills the excavation part 1, The tractor 10 crushes the subsoil part 1 and the spaces S2 and S3.

Specifically, the subsoil of the upper portion of the hydrophobic material layer 310 of the spaces S2 and S3 will be crushed.

As mentioned, the construction method according to the present invention does not use an excavator but uses the tractor 10 and the tractor-mounted culvert drainage pipe burial machine 100, so that the installation cost is reduced by 66.9% compared to the existing excavation type (excavation type 37.2 million won / It is economical because it can save 12.3 million won/ha from ha).
