Description

  The present invention relates to a conduit for a farm field. More specifically, the present invention relates to a field pipe body that can execute both an underground water supply function for supplying water from the underground of the field to the field and an underground air supply function for supplying air from the underground of the field to the field.

  Conventionally, the yield has been increased by supplying irrigation water from a perforated pipe buried underground.

  However, the amount of irrigation water in the field needs to be set appropriately according to the conditions such as the difference between field cultivation and rice cultivation, the state of crop growth, and the geology of the field. It is also required to minimize the loss of fertilizer in such irrigation. Furthermore, if the supplied water contains a large amount of foreign substances such as dust and earth and sand, these foreign substances may accumulate in the perforated pipe and impair the water flow performance.

  In order to solve the problem of the conventional underground irrigation, Patent Document 1 discloses that a perforated pipe is embedded in the ground of a farm and a water level setting device is installed on the downstream side of the perforated pipe. In the underground irrigation system that sets the water level of the field by adjusting the water level, an underground water supply pipe for supplying water from the water supply channel to the functional pipe is buried in the ground, and the underground water supply pipe and the perforated pipe Can be connected to the drainage side of the perforated pipe, the water supplied from the water supply channel can be supplied to the surface of the cultivated area, and surplus water in the cultivated area can be discharged to the underground water supply pipe A water supply tank is proposed.

  However, in the system according to the proposal of Patent Document 1, since the underground water supply pipe for supplying water to the perforated pipe is provided, the configuration is complicated and the construction cost is increased and the construction period is prolonged. There is a problem that.

  By the way, in the field, it is known that the growth of crops is improved by the presence of aerobic bacteria in the soil. This aerobic bacterial growth requires the presence of oxygen in the soil. For this purpose, it is preferable to supply oxygen, practically air, into the soil.

  However, the system according to the proposal of Patent Document 1 has a problem that only irrigation can be achieved due to the configuration.

The connecting portion with the air supply pipe 31 is provided rearward, and the connecting portion with the functional tube 41 is provided forward corresponding to the arrangement interval of the functional tubes 41. The connecting portion is formed by, for example, a T piece or a cross piece. In addition, the structure of the edge part of the distribution pipe 42 is not limited above, For example, an edge part may be made into elbow shape or T piece shape.

It is supposed to have.

  Next, the function of the agricultural field pipe body 1 having such a configuration will be described.

A. Underground water supply function When the power switch C1 is turned on when the water level of the drainage basin 21 is below the upper limit water level, the water supply pump P is activated to supply water to the water supply basin 11 from the water supply pipe 12, and then from the water supply connecting pipe 13 to the distribution pipe 42 It is distributed to the functional pipe 41 and irrigated underground. Thereafter, the automatic operation of the water supply pump P based on the detected water level of the water level detector W maintains the water level in the water level detection chamber 21b within a predetermined range, and predetermined underground water supply, that is, underground irrigation is performed.

B. Underground air supply function When the irrigation period is over, the water in the pipe body 2 is drained. Specifically, the partition plate 21a of the drainage basin 21 is removed, and the water supply basin 11, the water supply communication pipe 13, the distribution pipe 42, the function pipe 41, the water collection pipe 43, the drainage communication pipe 22, the drainage basin 21, and the function pipe 41 The water in the orthogonal bullet culvert 51 is drained into the drainage channel N through the drainage pipe 23. When drainage of the pipe main body 2 is completed, air enters the pipe main body 2 from the vent 32a, the upper end of the water supply tub 11, the upper end of the drainage tub 21, and the drainage end of the drain pipe 23. That is, the water supply communication pipe 13, the distribution pipe 42, the functional pipe 41, the water collection pipe 43, and the drainage communication pipe 22 are filled with air, and then the air in the functional pipe 41 enters the soil from the functional hole 41a. A part of the air in the functional tube 41 enters the bullet culvert 51 from the functional hole 41a, and then is supplied also from the bullet culvert 51 in a direction orthogonal to the functional tube 41 to enter the soil. As a result, air is supplied to almost the entire area of the field K.

C. Surplus water drainage function When surplus water is supplied to the field K due to heavy rain or the like, the surplus water is collected in the water collection pipe 43 by the function pipe 41 and then supplied to the drainage basin 21 by the drainage connection pipe 22. The partition plate 21 a overflows and enters the discharge chamber 21 c, and then drains into the drainage channel N through the drain pipe 23. Therefore, there is no risk of crop root rot caused by excess water.

  Thus, in this embodiment, since it is not necessary to separately embed a water supply pipe below the functional pipe 41, the configuration can be simplified and the construction can be simplified. Further, since the configuration is simplified, it is possible to reduce manufacturing and construction costs and shorten the construction period.

  In addition, when underground irrigation is not required, aerobic bacteria can be propagated by underground air supply, and soil can be improved.

  As mentioned above, although this invention has been demonstrated based on embodiment, this invention is not limited only to this embodiment, A various change is possible.

  For example, in this embodiment, water is supplied to the water tank 11 by the water supply pump P. However, when water is supplied from a pipeline, an electromagnetic valve is provided and water is supplied by controlling the electromagnetic valve. May be.

  Further, in the present embodiment, water is supplied from the irrigation channel M to the water tank 11, but water may be supplied from the drainage channel N.

  The present invention is applicable to agriculture.
