Level of ground water automatic observing system

Technical field

This utility model is related to building field water proof anti-seepage technical field, more particularly to a kind of level of ground water automatic Observation system System.

Background technology

At present, the mode of observation of groundwater levels mainly adopts following several ways：First, workman is put into well with a lining rope In, the position of rope is recorded after hearing sound, this mode has the disadvantage that anthropic factor is relatively more, it is difficult to precise control；2nd, surveying A both positive and negative polarity is carried on rope, both positive and negative polarity can form conductor in being put into water, can give test a upper signal, re-record the length of lining rope The shortcoming for spending this mode is that measurement can be more accurate for skilled worker is compared, and such as measures 15 meters of depth, Front 10 meters of workmans can quickly be put into lining rope, and 5 meters slowly can be put into afterwards, if unfamiliar workman, is put into speed per hour Degree cannot precise control, the gauge head of lining rope can be caused to be deep into a certain distance in water, caused measurement precision error occur, be Error is avoided the occurrence of, workman needs repeated measurement, and measurement is required for the gauge head to wipe clean every time, so when causing measurement Between it is very long.For multiple wells, the substantial amounts of experience of workman and time will be expended to measure.

Utility model content

The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of level of ground water automatic Observation system System, water level information can count in automatic data collection well.

This utility model for achieving the above object, is employed the following technical solutions：

Specific embodiment

Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1-Fig. 3 institutes Show, a kind of level of ground water automatic observing system, including single-chip microcomputer, host computer, installed in the pithead position of inside and outside water level well Laser range sensor and it is placed in each well and floats water-level observation reflecting plate on the water, the laser range sensor Transmitting terminal be vertically injected on the water-level observation reflecting plate；Each well real-time water level is believed by the laser range sensor Breath sends the single-chip microcomputer to by wireless module；Each well real-time water level information is passed by the single-chip microcomputer by gsm module Give designated mobile phone or be sent to the host computer.Laser range sensor can be placed on interior water by workman when in use The well head of position well and outer water level well, just can interpolate that specific position by the water difference in monitoring between water level well and outer water level well Whether seepage.

Using the data of the existing monitoring well location SEA LEVEL VARIATION in foundation ditch scene, the substantially model of Leakage of Foundation Pit point is primarily determined that Enclose.Suspecting in the range of breakthrough, using my house journal's technology, water level pipe is symmetrically buried by outside Jing special process in the foundation ditch If, and water level pipe carries out level measuring on the outside of timing internally.Comprehensive surveyed data, if outside somewhere water level pipe water level is compared with other Water level is low, and inner side correspondence water level pipe water level compared with inner side other place water level pipe water level height, then can determine that water level pipe location at this Domain is likely to occur leak.

As shown in Figure 4 and Figure 5, curve above in Fig. 5 is the outer water level pipe water level of foundation ditch, and curve below is base underground water Position pipe water level, such as foundation ditch ABCD, 1 ＇ -28 ＇, 1-28 are respectively the water level monitoring pipe that external symmetry is laid in foundation ditch.According to AB sections As schemed, the region between 2-6 water level monitoring pipes is the area for being likely to occur leak to the achievement curve that water level monitoring achievement is drawn Domain.

Encrypt in the region for being likely to occur leak and lay different depth water level monitoring pipe, it is final to determine the accurate position of breakthrough Put.
