GROUNDWATER LEVEL OBSERVATION EQUIPMENT, INSTALLATION METHOD FOR GROUNDWATER LEVEL OBSERVATION EQUIPMENT AND GROUNDWATER LEVEL OBSERVATION METHOD
To provide groundwater level observation equipment observing distribution and water level fluctuation of groundwater by a siphon principle using neither motive power nor a power source, installation method for the groundwater level observation equipment, and a groundwater observation method.SOLUTION: Groundwater level observation equipment comprises: a groundwater level observation tube 12 inserted into and installed inside a groundwater level observation hole 11 and having a groundwater inflow/outflow hole 13; a water storage tube 14 provided in a lower portion inside the groundwater level observation tube 12; a water level display tube 19 installed apart from the groundwater level observation tube 12 and having an outside air hole 20 in the upper portion of the water level display tube 19; and a communication tube 16 in which one-end opening 16a of the communication tube 16 is immersed in water of the water storage tube 14 and the other-end opening 16d of the communication tube 16 is immersed in water injected into the water level display tube 19 and which fills between the groundwater observation tube 12 and the water level display tube 19 thereby communicating the tube 12 and the tube 19 with each other. Thus, the groundwater level inside the groundwater level observation hole 11 is displayed with the water level display tube 19 by the siphon principle.SELECTED DRAWING: Figure 1
【課題】地下水の分布や水位変動を動力や電源を用いることなくサイフォンの原理で観測する地下水位観測装置、地下水位観測装置の設置方法及び地下水位の観測方法を提供すること。【解決手段】地下水位観測孔１１内に挿入設置され、地下水出入り孔１３を有する地下水位観測管１２と、この地下水位観測管１２内の下方に設けた貯水管１４と、前記地下水位観測管１２から離れて設置され、上部に外気孔２０を有する水位表示管１９と、前記貯水管１４の水中に連通管１６の一方端開口部１６ａを浸漬し、前記水位表示管１９に注入した水に前記連通管１６の他方端開口部１６ｄを浸漬してこれら地下水位観測管１２と水位表示管１９の間を、水を充填して連通した連通管１６とを具備し、前記地下水位観測孔１１内の地下水位を前記水位表示管１９にてサイフォンの原理で表示する。【選択図】図１
