摘要： PROBLEM TO BE SOLVED: To provide a groundwater environmental preservation method in a bypassing system of natural flow of a groundwater system, which can preserve the volume of groundwater system, can prevent degradation of water quality, and can positively improve the water quality. SOLUTION: Groundwater is collected into an upstream groundwater purifying well 14a through a crashed rock section 17a having activated carbon mixed thereto, and the groundwater in which noxious materials are adsorbed and eliminated by the activated carbon is introduced from a water flow pipe 16 through a linking pipe 26 passing underground below a construction zone 15 of an underground structure 25, into a downstream well 14b. Then, the groundwater is diffused from a crashed rock section 17b into a downstream ground 13d. The groundwater purifying means may be set in the downstream well 14b, the linking pipe 26, or the water flow pipe 16. Thus, free flow of the groundwater system can be preserved between the two sides of the underground structure, and at the same time purification of groundwater can be carried out easily and at low cost.

摘要： PROBLEM TO BE SOLVED: To provide a sandbag for vegetation, effective for preventing the flow out of vegetation soil by drainage, free from the erosion of the filled vegetation soil with wave and water current and capable of stably keeping an aquatic vegetation area over a long period.
SOLUTION: This vegetation sandbag 40 forms a vegetation soil layer of an aquatic plant zone such as reed zone formed on a prescribed area. The bag 36 for filling the vegetation soil 38 has a woven fabric 42 having fine mesh to prevent the flow out of soil 38 from the bag at least at the circumferential side face 36a and the bottom face 36b. A nonwoven fabric 44 having coarse mesh to enable easy extension and growth of the new sprouts and stalks of various aquatic plants is openably placed at the upper face 36c of the bag. Since the fine-mesh woven fabric 42 is used at the circumferential side face 36a and the bottom face 36b of the bag 36, there is no flow out of the soil particles of the vegetation soil 38 from the bag together with water in drainage. The erosion of the filled vegetation soil with wave, and the like, is prevented by the coarse-mesh nonwoven fabric covering the upper face of the vegetation soil filled in the bag.

摘要翻译：要解决的问题：为了提供一种植被沙袋，有效防止被排水的植被土壤流出，没有波浪和水流侵蚀填充的植被土壤，能够稳定地保持水生植被面积长期以来。
解决方案：该植被沙袋40形成水生植物区域的植被土层，如在规定区域形成的芦苇区。用于填充植被土38的袋36具有细网的机织织物42，以防止至少在周向侧面36a和底面36b处从袋中流出土壤38。具有粗网的无纺布44可以容易地延伸和生长各种水生植物的新芽和茎，可开放地放置在袋的上表面36c处。由于在袋36的圆周侧面36a和底面36b使用细网状织物42，所以在排水时不会将植被土38的土壤颗粒与水一起从袋中流出。通过覆盖填充在袋中的植被土壤的上表面的粗网无纺织物防止填充的植被土壤与波浪等的侵蚀。版权所有（C）2005，JPO＆NCIPI
