を構築できる。In addition, in this water collection groove 31, the center part 3A in the width direction of the fairway 3 is lower than its both side edges 3B, 3B, and rainwater etc. to the fairway 3 flows down along the low center part 3A to its lower end. However, it is suitable for remodeling the existing fairway 3 where a large amount of rainwater containing fertilizers, pesticides, etc. is collected in the lower part of the golf course, and the water is collected along almost the entire length of the fairway 3. Although it is necessary to construct the groove 31, conversely, since the water collection groove 31 is constructed along almost the entire length of the fairway 3, the amount of water collected per unit surface length of the water collection groove 31 is reduced, and therefore, Even if the width of the water collecting groove 31 (in the left-right direction in FIG. 6) is made relatively narrow, it is possible to construct one having sufficient water permeability.

Water floods the sand layer 15, coarse sand layer 14, and gravel layer 13, and fertilizers, pesticides, etc. mixed with rainwater etc. adhere to these areas.
After remaining and being purified by the activity of bacteria living underground, it collided with the crushed stone layer 12 and was decelerated, and the fertilizers, pesticides, etc. mixed in the rainwater etc. settled to the lower part and were purified. Thereafter, water is collected into the water collecting pipe 39 from its peripheral wall and discharged from its bottom end via the manhole 25D.

よる公害発生を防止できる。(1) Even if fertilizers, pesticides, etc. spread or sprayed on the golf course, especially on the fairways, flow around the hole due to rainfall, watering, etc., there will be no need to leave an appropriate gap on the fairway of the hole. The water is collected in horizontal drainage ditches, and as it flows down through the thick, highly permeable sandy strata,
It adheres to and remains in the sand layer, and after being purified by the activity of bacteria living underground, it sinks to the bottom due to deceleration caused by collision with the crushed stone layer at the bottom of the drainage ditch and is filtered.
After being further purified by bacteria living underground,
Water is collected from the permeable peripheral wall of the water collection pipe buried at the bottom of the water collection ditch and discharged outside the golf course via the drainage channel, so fertilizers mixed with rainwater, etc. discharged outside the golf course, The concentration of pesticides, etc. is significantly reduced, and even if it rains or sprinkles water immediately after spraying fertilizers, pesticides, etc. on the golf course, it is possible to prevent pollution caused by the fertilizers, pesticides, etc. flowing out of the golf course. .

期に旦って確保できる。(2) Fertilizers, pesticides, etc. that adhere to and remain on the highly permeable sand stratum of water collection ditches installed horizontally at appropriate intervals on the fairway.
Vegetation grows on the surface of the sandy stratum, and the grass roots that extend into the sandy stratum gradually absorb fertilizer over a long period of time and are used effectively. Since the essential part of the highly permeable sandy soil is purified by the activities of the living bacteria, fertilizers, pesticides, etc., which are subsequently sprayed or sprayed on the fairways and other golf courses, can enter the sandy soil layer by rainwater, etc. The flow and adhesion of fertilizers, pesticides, etc. to the same sandy stratum, and purification properties are ensured over a long period of time.
Furthermore, the function of suppressing the outflow of fertilizers, pesticides, etc. spread or sprayed on the fairway to the outside of the golf course can be ensured for a long period of time.

く恐れなく容易に改造できる。(3) By installing multiple water collection grooves horizontally at appropriate intervals on a vast fairway, it is possible to construct a purification device and control the runoff of fertilizers, pesticides, etc. at the golf course. In particular, if one surface of a fairway has hardened due to tread pressure, etc., instead of excavating and reconstructing the entire fairway, excavating only a part of it, forming a sand layer with good permeability,
By burying water collection pipes with a coarse sand layer, crushed stone layer, and permeable surrounding walls, it is possible to regenerate fairways with excellent permeability for rainwater and purification of sprayed or sprayed fertilizers, pesticides, etc., and as a result, water permeability. Existing fairways with almost no water permeability or significantly reduced water permeability and where there is a risk of pollution due to spraying or spraying of fertilizers, agricultural chemicals, etc., are being treated as having high water permeability such as rainwater and causing pollution due to sprayed or sprayed agricultural chemicals. It is relatively simple to modify the fairway so that there is no fear of occurrence, and moreover, it can be easily modified without the risk of increasing costs.

At the same time, extend the end to the same low-lying area, or
By constructing the side walls of the water collection ditch in an inclined shape that expands toward the lowland area, it is possible to improve the drainage performance of the entire golf course, suppress the runoff of fertilizers, agricultural chemicals, etc., and improve purification efficiency.

たフェアウェイに簡易に改造できる。(6) A water collection groove is provided along the entire length of the fairway in the central part where the center part in the width direction is lower than both sides thereof, and a thick highly permeable sand layer or coarse sand layer is provided in the water collection groove. The water is collected in the lower part of the water collection ditch through the gravel layer, etc., and the rainwater collected from the permeable peripheral wall of the water collection pipe buried in the lower part is transferred to the drainage channel near the golf course. By constructing the fairway so that water drains to a reservoir etc. through the fairway, the center part is lower than both edges, and only the center part is excavated in the length direction without excavating the entire fairway, resulting in good water permeability. By burying sand layers, coarse sand layers, crushed stone layers, water collection pipes, etc., fairways can be easily remodeled into fairways with excellent water permeability, control of runoff of fertilizers and agricultural chemicals, and purification properties.
