The irrigation tube, which is obtained by drilling small holes at appropriate intervals in the longitudinal direction of a flat long tube made from a plastic tube such as polyolefin, is lightweight, easily bendable, and can be reeled. Since it can be rolled up, it is convenient for transportation, installation, storage, etc., and the location of the irrigation tube can be easily changed depending on the size of the field, different types of plants, and the degree of plant growth. There are advantages such as:

無駄に消費されることもしばしばであつた。 Therefore, when irrigating a large field, the irrigation tubes were arranged appropriately to ensure uniform watering, but when irrigating a field with limited topography, it was necessary to In some cases, it may be necessary to install an irrigation tube at the edge, and in such cases, not all of the water gushing or dripping from the irrigation tube is supplied to the field, and half of the water is sprinkled outside the field.
It was often wasted.

ある。 For these reasons, a irrigation tube that can be used to irrigate only one side of the tube is required. However, in conventional single-sided irrigation tubes, small watering holes are simply drilled in a row on one side of the irrigation tube. Therefore, there is a problem in that it is not possible to uniformly irrigate a wide area on one side, especially in the width direction of the irrigation tube.

In other words, the present invention is flat when water is not flowing.
It is a long tubular body that becomes rounded when water passes through it.
Multiple rows of small holes are drilled on only one side of the flat surface, and the rows of small holes are unevenly distributed on one side of the central axis in the longitudinal direction, and the per unit length of each row of small holes is The irrigation tube is characterized in that the number of perforations increases successively as each row of small holes moves away from the central axis in the width direction.

向も適正にコントロールすることができる。 According to the present invention, when laying the irrigation tube on the ground or suspending it in the air when water is not flowing, the irrigation tube is flat, so it sits comfortably, and the tube itself is easily prevented from twisting. The direction of water sprinkling through the small holes can also be appropriately controlled.

る。 In the present invention, multiple rows of small holes are drilled, such as 51, 52, and 53 shown in Fig. 4, and water is spouted into the air from these small holes to irrigate an area a certain distance from the irrigation tube. It is. FIG. 5 is a cross-sectional view of the irrigation tube showing the location of the small holes. small holes 51, 52 and 5 at distances a, b and c from the center of the irrigation tube;
3, the number of irrigation tubes per unit length increases sequentially as shown in Figure 4, and the amount of water sprinkled per unit length by the small holes at each point a, b, and c of the irrigation tube is , are adjusted so that they become successively larger values as shown in FIG.
これにより、第７図に示したように、灌水チユ

らで、その分、外側の孔の数を増やして散水量を
増加してやる必要があるからである。 Thereby, as shown in FIG. 7, water can be uniformly applied over a wide area in the width direction of the irrigation tube. Here, simply by drilling multiple rows of small holes on one side of the central axis of the tube, with the same number of holes in each row, it is not possible to uniformly irrigate a wide area in the width direction. This becomes possible only when the number of perforations per length increases sequentially as each row of small holes moves away from the central axis in the width direction. In other words, if the number of holes in the multiple rows of small holes in the irrigation tube are the same, the outer rows will spray water furthest away, so the flying distance will likely vary, causing the water to be dispersed over a wide area or scattered. As a result, the amount of water per unit area in the outer rows is smaller than that in the inner rows, and the entire watering range in the width direction cannot be uniformly irrigated. This is because it is necessary to increase the number of holes and increase the amount of water sprinkled.

ことができる。 For example, paper pots and seedling boxes are lined up in rows to raise seedlings of rice, beets, etc., but they are not always lined up in an orderly manner, and the distances between the seedling boxes vary; By simply installing the irrigation tube of the present invention only near one side of the box, each seedling growing box can be uniformly watered.

ユーブを調節すればよいので作業が簡便である。
これに対し、両側潅水チユーブでは、両側の畝に
潅水しているので潅水が重複して潅水量の均一性
が乱されることに注意する必要がある。 In addition, in the field, irrigation tubes are often installed along the ridges, and as the crop grows, the height of the crop increases, and the leaves of the crop become an obstacle to watering from the irrigation tube. It is desirable to adjust the watering distance by moving away from the ridges so that the watering can spread over a wide area, but when installing conventional tubes that irrigate on both sides between the ridges, the spacing between the ridges is fixed, so the irrigation tube The distance from to the crops on both sides is also fixed and cannot be changed.
However, according to the irrigation tube of the present invention, since irrigation is performed on one side, it is only necessary to adjust the irrigation tube by focusing on the ridges on one side, which simplifies the work.
On the other hand, with double-sided irrigation tubes, water is applied to the ridges on both sides, so care must be taken that watering overlaps and the uniformity of the amount of water is disturbed.
また本考案の潅水チユーブはハウスのフイルム

ない。 In addition, even if the irrigation tube of the present invention is installed near the greenhouse film, it can only irrigate the side opposite to the vinyl film, and unlike conventional double-sided irrigation tubes, irrigation water reaches the greenhouse film and forms drops. They do not block the sunlight, and unlike conventional structures, they are installed between the ridges in the greenhouse and do not obstruct work or traffic inside the greenhouse.

景観を損ねることもなく、さらに潅水量も少なく
てすむので経済的である。 In addition, in ordinary households, when watering stepped chick beds for bonsai, vegetable gardens, gardens, etc., conventional irrigation tubes water both sides, so
Irrigation tubes had to be installed in the center of gardens, etc., which became an obstacle when walking in vegetable gardens and gardens, and spoiled the scenery, but according to the irrigation tube of this invention, Irrigation tubes can be installed at the edges of vegetable gardens and gardens, for example at the border with buildings, fences, etc., and the desired area can be uniformly watered, so it does not become an obstacle to walking.
It is economical because it does not damage the landscape and requires less irrigation.
さらに本考案の潅水チユーブは、非通水時は偏
平であるため、潅水チユーブを移動させた後でも
地上に置くだけで潅水される方向が自ずと決まる
ので、潅水チユーブの移動操作が簡便となる。 Furthermore, since the irrigation tube of the present invention is flat when water is not flowing, even after the irrigation tube has been moved, the direction of irrigation is automatically determined by simply placing it on the ground, making it easy to move the irrigation tube.
実施例

It is possible to spray water evenly over a wide area up to approximately 150 cm, whereas the single-row perforation type sprays water uniformly over a wide area up to approximately 150 cm.
Water can only be sprinkled in an extremely narrow area of ~120cm,
Moreover, the amount of water sprinkled is uneven. In addition, if the number of perforations in each row is the same even in a multi-perforation type, although water can be sprayed over a wide area in the width direction, the amount of water sprinkled is uneven, and there is a problem in that the amount of water is higher near the tube and decreases as you move away from the tube.
