PUMPING WELL WITH WATER INJECTION PIPE
To reduce a labor for providing a water injection pipe when a pumping well with a water injection pipe is installed.SOLUTION: A pumping well 100 with a water injection pipe includes: a well pipe 1 that is vertically installed in the ground and has an underwater inflow hole 1a on a peripheral wall 11; a strainer 2 that is annularly mounted on the well pipe 1 and has a water passing part 21 for passing groundwater; and a pillow material 4 composed of at least one rod material or pipe material that is interposed between an outer peripheral surface 11 of the well pipe 1 and the strainer 2 and supports the strainer 2. At least one pillow material 4 includes a water injection port 3a for injecting a liquid while serving as the water injection pipe 3.SELECTED DRAWING: Figure 1
【課題】注水管付揚水井を設置するにあたり、注水管を設ける手間を削減する。【解決手段】注水管付揚水井１００は、地中に垂設されるとともに周壁１１に地下水流入孔１ａを有する井戸管１と、井戸管１に環装されるとともに地下水を通す通水部２１を有するストレーナ２と、井戸管１の外周面１１とストレーナ２に挟設されてストレーナ２を支持する少なくとも１本の棒材、又は管材からなる枕材４とを備えている。枕材４は、少なくとも１本が注水管３を兼ねて液体を噴射する注水口３ａを備える。【選択図】図１
