一、井窖修建。选地势高、地下水位低、背风向阳处修建。井窖由井筒和贮姜洞两部分组成。井筒垂直向下,深度依地下水位高低而异,北方井深5米~7米,南方井深2米~3米。建井窖时,先挖一个直径80厘米的圆井口,随即向下挖,井筒由上至下渐粗,底部直径可达1.1米~1.?
First, well cellar construction. Elevated topography, groundwater level is low, leeward sunny place to build. Well cellar storage and storage of ginger hole by two parts. Wellbore down vertically, the depth varies according to the level of groundwater level, the northern well depth of 5 meters to 7 meters, the southern well depth of 2 meters to 3 meters. When constructing a pit, first dig a round wellhead with a diameter of 80 cm and then dig it down. The wellbore is gradually roughed from top to bottom, and the bottom diameter can reach 1.1 m ~ 1.
