DRAINAGE WELL AND CONSTRUCTION METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a drainage well that is excellent in drainage property from a natural ground even on the ground with low water permeability and a construction method thereof.SOLUTION: A drainage well 10 comprises: a borehole 1 that is bored in the ground G; a perforated pipe 2 that is fitted to a porous wall of the borehole 1; and a desiccant 7 and a drainage pump 3, which are stored in the perforated pipe 2. In the drainage well 10, the desiccant 7 and the drainage pump 3 are stored in the perforated pipe 2 fitted to the porous wall of the borehole 1. The desiccant 7 enables effective increase in the drainage volume from the ground whose water permeability is too low to obtain sufficient drainage volume by an existing drainage well.SELECTED DRAWING: Figure 1
【課題】透水性の低い地盤においても原地盤からの排水性に優れた排水井戸とその構築方法を提供する。【解決手段】地盤Ｇに造成されている造成孔１と、造成孔１の孔壁に取り付けられている多孔管２と、多孔管２に収容されている乾燥剤７および排水ポンプ３と、からなる排水井戸１０である。排水井戸１０は、造成孔１の孔壁に取り付けられている多孔管２の内部に、乾燥剤７と排水ポンプ３が収容された構成を有しており、この乾燥剤７により、従来の排水井戸では十分な排水量が得られないような透水性が低い地盤からの排水量を効果的に増加させることを可能とした。【選択図】図１
