ができるときは、曲りの数が少なくて済む。A water intake device 4 is mounted in the downspout 2. As shown in FIG. 3, the water intake device 4 includes a receiving cylinder 5 and an overflow pipe 6. The receiving cylinder 5 extends just below the upstream downspout 2a so as to be continuous therewith. The overflow pipe 6 branches off from the upper part of the receiving cylinder 5 in the horizontal direction, and then bends and extends downward. The end of the overflow pipe 6 is again bent and connected to the downstream gutter 2b. As shown by the chain line in FIG. 3, when the drain pipe 3 can be provided directly below the overflow pipe 6, the number of bends can be reduced.

ば、竹の垣根になり、見た目がよい。The watering pipe 7 is guided horizontally from the bottom of the receiving cylinder 5. The watering pipe can be guided not only in one direction but also in two directions as shown in FIG. The watering pipe 7 is piped so as to cover the planting 8 under the eaves, and is supported by a support 9. If the sprinkling pipe 7 is made of plastic bamboo together with the support 9, it becomes a bamboo fence and looks good.

８の上に降り注ぐ。In this watering device, when it rains, the rain that has fallen on the roof collects in the eaves gutter 1 and then flows into the downspout 2a,
Furthermore, it flows into the receiving cylinder 5 of the water intake device 4. The water that has entered the receiving cylinder passes through the watering pipe 7 and falls down onto the planting 8 in an arc from the watering hole 7a.

る。When the rain becomes intense and the amount of water flowing down the upstream downspout 2a increases, the water level of the receiving tube 5 rises and eventually overflows into the overflow pipe 6, and the overflowing water flows downstream. It flows into the downspout 2 b and flows off through the drain pipe 3.

4 is an example. The overflow pipe 16 has a large diameter, and the receiving cylinder 1
5, and a drain hole 17 is formed in the upper pipe wall of the receiving cylinder 15.
During the light rain, rainwater enters the receiving cylinder 15 from the upstream downspout 2a and is sprinkled from the sprinkling pipe. When it rains heavily, the water overflowing from the receiving cylinder 15 passes through the drain hole 17, passes between the overflow pipe 16 and the receiving cylinder 15, and flows out to the downstream downspout 2 b.

ようにしたので、過不足ない灌水が可能である。According to the first aspect of the present invention, a water intake device is provided in the middle of a downspout, and a watering pipe is guided from the water intake device to planting. Planting under eaves can be protected from running out of water. When the rainfall is small, the entire rainwater flowing down the downspout is used for irrigation. When the rainfall is strong, the rest of the irrigation water is allowed to flow to the drainpipe, so that sufficient irrigation can be performed.
