How to accurately find groundwater resources, is the problem of every drilling people, who mastered the skills to find water, who will be able to seize the opportunity in the market, the following will give you a few masters easily not to pass on the water finding skills, to help you out of the big water, make a lot of money. That construction drilling in the field how to find the construction site, let us know today.

1. Find a very low place in a high place


Depending on the terrain, water can be found in valleys or areas with low ground. For example, in a well, groundwater usually accumulates in the valley, or is drained.


The water surface is a spring. In gullies of coastal or lakeside areas, freshwater lenses are formed due to the concentrated infiltration of rainwater and surface water, which are concentrated in the lenses.


In low-lying areas of submerged valleys, groundwater in sand dunes in desert areas is buried in depressions between sand dunes and sand dunes.


2. Rock formations with good permeability are found in the rock formations with good permeability".


The water found in the mountainous area (lime zone) has good rock fissures and good permeability because of the good permeability of the rocks, the deeper precipitation in the fissures and the good permeability of the groundwater.


There are some difficulties in such a deep well with a depth of tens to hundreds of meters, in a scattered mountainous settlement. I am looking for water in such an area.


To find a shallow water barrier or a relative water barrier. In this way, the water-resisting layer prevents groundwater from continuing to seep through the upper part and accumulates in the waterproofing layer. Such an aquifer, although sometimes small in volume, is shallow and can be used for small settlements.


3. A rock layer with good permeability is found in a rock layer with poor permeability.


In mountainous areas where certain igneous or metamorphic rocks are distributed, the deep part of the bedrock of the well is developed without structural fractures, and its permeability is poor, and the upper part of the bedrock consists of the following parts.


After a long period of weathering, deep weathering crusts with good permeability are formed in the weathering crusts and soil accumulation layers remaining on the slopes and foothills of the mountains, and voids and fissure water are found.

 ground water detector

PQWT-GT series natural electric field intelligent one key into a map to find water detector is the use of natural electric field as a working field source, based on the resistivity difference of underground rock ore or ground water, on the ground to measure the natural electric field N different frequency electric field components, according to their change law to study the different geological body generated by the abnormal changes to achieve an electrical method of exploration method to solve geological problems.


The instrument is using the earth's natural electric field source does not need to pass the artificial electric field that omits the clumsy power supply system so as to achieve simple operation, the instrument is lightweight, the data collected by the instrument through the instrument's unique internal insult computing function to achieve automatic presentation of curve, geological profile, according to the profile to clearly understand the structure of geological layers, can quickly determine the specific information such as rock layers, caves, aquifers.
