Embodiment Construction

[0012] exist figure 1 and figure 2 Among them, the interior of the field is divided into a plurality of cultivation areas 13 by agricultural roads 11 and ridges 12, and a water supply channel 14 is provided on one agricultural road part, and a drainage channel 15 is provided on the other agricultural road part. In each farming area 13, an underground irrigation system for appropriately setting a water level according to the type of crops and their growth conditions is respectively installed. In addition, the water supply passage or the drainage passage may be installed at any position according to the conditions of the field, and may be provided on the ridge of the field, or may be formed by pipelines.

[0013] In the underground irrigation system, a plurality of perforated pipes 22 branched from the collection pipe 21 are buried side by side in the ground of the cultivation area 13 at equal intervals, and a water level setter 31 is installed at the same time from the collec...

Abstract

This underground irrigation system comprises the following steps: embedding a porous pipe 22 into the ground of the fields (cultivation areas 13), setting up a water level setting tool 31 on the lower-stream side of the porous pipe, regulating a drainage water level by the water level setting tool to set the water level of the field, embedding an underground water supply pipe 41 for supplying water for use from a water supply channel 14 into the ground of the field, connecting the underground water supply pipe 41 with the porous pipe 22 at the drainage side of the porous pipe to supply the water for use from the underground water supply pipe to the porous pipe.

Description

technical field [0001] The present invention relates to an underground irrigation system. Specifically, it relates to an underground irrigation system for setting the ground water level or surface water level of a field by adjusting the drainage water level from a perforated pipe buried in the ground. Background technique [0002] Underground irrigation, which has been continuously carried out in recent years, is to adjust the groundwater level of the field during cultivation, to replenish water through capillary phenomena, and to increase the yield of crops by adjusting the groundwater level to a water level suitable for crops. This kind of underground irrigation is usually buried in the ground of the field by the underdrain drainpipe that is made of perforated pipes, the remaining groundwater in the ground is discharged into the drainage channel, and the underdrain drainpipe is also used to supplement the insufficient water (for example, refer to Page 2 and figure 1 , f...
