PUMPING/REDUCTION WELL, WATER SUPPLY METHOD THEREFOR, UNDERGROUND WATER PUMPING/REDUCTION SYSTEM, ROAD HEATING SYSTEM, AND SNOW MELTING SYSTEM
PROBLEM TO BE SOLVED: To prevent fine particles from being deposited in a pumping/reduction well.SOLUTION: A pumping/reduction well comprises: a water permeable pipe which is disposed in a water stagnation layer and includes multiple holes on a side face; a tip reinforcing basin which is fitted to a tip of the water permeable pipe; a drain pipe of which one end is disposed within the tip reinforcing basin; and a water supply pipe which is disposed on an upper part of the drain pipe. It is preferable that one end of the water supply pipe is disposed within the tip reinforcing basin. It is preferable that at least a part of the tip reinforcing basin is located in a lower layer at a lower side of the water stagnation layer. Further, it is preferable that at least a tip portion of the tip reinforcing basin is formed conical, formed in a pyramid shape or bullet-shaped.SELECTED DRAWING: Figure 1
【課題】微粒子が揚水兼還元井に堆積するのを防ぐ。【解決手段】揚水兼還元井において、滞水層に配置された、側面に複数の孔を有する透水管と、透水管の先端に取り付けられた先端補強桝と、一端が先端補強桝内に配置された排水管と、排水管の上部に配置された給水管と、を有する。給水管の一端は先端補強桝内に配置されていることが望ましい。また、先端補強桝の少なくとも一部は滞水層下の下層にあることが望ましい。さらに、先端補強桝の少なくとも先端部は、円錐形状、角錐形状又は砲弾形状であることが望ましい。【選択図】図１
