(4) do scale with paint or adhesive tape on surfaces of wires, scale starting point in two test pencil pen tip line midpoints, Every 5 meters or every 10 meters of patterns for changing scale；

(5) faucet section is inserted on multimeter dial plate, multimeter gets to resistance gear, and test pencil section is slowly put into hydrology hole In, one number of edges scale of one side unwrapping wire, when seeing that general-purpose list index starts deflection, depth corresponding to electric wire be exactly earth's surface to The depth of lower water surface, records the depth data；Electric wire is slowly risen at critical groundwater table, slowly decline several times, is observed again Throw of pointer records each depth data；Above-mentioned depth data is averaged, obtains level of ground water data；

(6) electric wire is slowly packed up by wire spool；Complete a hydrology hole underground water level measurement.

In the present invention, the electric wire should it is soft, have insulated hull outside, temperature susceplibility is low, and retractility is small, be mainly used for plus The wire length of long pen meter of universal meter；For multimeter for incuding whether test pencil touches the water surface, pouring weight lies in test pencil section, is used for electric wire It is straightened.Necessary small in size, the average weight of the pouring weight, this is because pouring weight volume is easy greatly very much to be stuck in hydrology drilling, weight Amount is too small to be difficult to electric wire straightening, and weight can then obtain pulling wire greatly very much elongated, and weight is too small or mostly will affect very much measurement Precision, usually selecting diameter is the reinforcing bar or similarly sized screw of 10mm, long 10cm, when being monitored on the spot, the choosing of pouring weight Selecting can act as one sees fit according to above-mentioned requirements, not be strict with.

The present invention has the advantages that at low cost, light-weight, small in size, easy to carry；Device used be all conventional device, Low manufacture cost, easy to make, not only measurement accuracy is high but also reusable；Measurement method simple possible.
