Technical field
The present invention relates to hydrogeological observation technology, particularly a kind of method observing multi-layer Underground Water water level.
Background technology
Underground water table refers to the elevation of the water surface in underground reservoir.Initial water level, fixed level, wet season water level, dry season water level can be divided into according to probing observation time, freeze front water level etc.
Groundwater level decrease reason is mainly: one is: human factor, mainly the excessive use of the mankind.It two is natural cause.As earthquake causes the sinking etc. of the raising of physical features, buried channel; Changing its course of river; The change etc. of weather.
Underground water table rises natural cause and artificial origin:
The rainfall amount short time increase, karst subterranean river to change, Anomalies of Seismicity, these all may cause underground water table to rise, and belong to natural cause.Artifact interference underground water table divides again two kinds, and one is rational, and one is irrational.Reasonably such as Baotu Spring, Jinan, Dunhuang, Gansu Province Crescent Spring just need regular moisturizing, raise underground water table, to keep tourist sight.Irrational is agriculture flood irrigation, and irrigation water is too much, and draining not in time, causes underground water table to raise, and even can cause the disaster of secondary salinization.
Need when hydrogeological investigation to observe groundwater level long-term dynamics, between water-bearing zone and the top in top layer water-bearing zone all has water-resisting layer, the groundwater level in a water-bearing zone can only be observed in same boring dynamic, in order to observe different water cut layer underground, areal dynamic, each water-bearing zone needs construction one boring, quantities is large, drops into high.Urgently research and develop a kind of in same hydrogeological hole, observe multi-layer Underground Water water level observation procedure and device simultaneously.
