METHOD OF MEASURING LEVEL OF SEEPAGE WATER

摘要

PURPOSE: A seepage water level measuring method is provided to precisely measure the level of seepage water collected in a pipe at a reclaimed land. CONSTITUTION: A pipe having plural through holes and a large diameter is laid in a reclaimed land. A cover well is opened in an upper part and closed in a lower part, and integrally fixed in the pipe. A pipe having a small diameter is inserted to allow seepage water to flow into a through hole in an upper opening of the upper cover well and the lower part of the pipe having a small diameter. A cathode(9a) and an anode(11a) as detecting terminals are inserted to the small diameter pipe. A scale on lead wires(9,11) connected to the cathode is read in conducting the cathode and the anode. The level of seepage water collected in the small pipe is measured with subtracting the scale of the lead wire in the cathode from the length of the small pipe.
