I believe the word "well drilling" is not new to us all, as it is used in our daily life and industrial enterprises. Many consumers are curious about how to drill a well, so here is the correct way to drill a well.
1. Configure the right pump
After completing the well, you should measure the water level of the well and the corresponding water output according to the construction and drainage of the well, and then determine the total head of the pump according to the height difference from the ground to the dynamic water level and the irrigation method you use, and the working head of the pump should not exceed the water volume of the well.
2. Reasonable well discharge
The borehole location arrangement should be reasonably arranged according to the actual local hydrogeological situation. No hydrogeological information should be used as the basis for borehole arrangement by referring to the existing water source wells nearby. In areas where shallow groundwater is not abundant, must not blindly drill shallow wells; in areas where shallow groundwater is more abundant, it is appropriate for farmers to build their own shallow wells, but the borehole arrangement should not be too dense to avoid mutual influence between neighboring wells.
3. Use the correct construction method
There are two construction methods for large mouth wells: one is the large trenching method, manual excavation or blasting construction; the other is the sinkhole method, drainage construction or no drainage construction. For the construction corresponding to pumping type, two methods are generally used: mechanical slinger and manual slinger, using the gravity effect of the slinger to drive the suction pipe directly into the ground.
The well drilling company has introduced us to the method of well drilling, and also let us understand more clearly and distinctly some general knowledge of well drilling, if you need to know you can consult our well drilling company.
4, the use of reasonable physical ground water detector
Now there are two kinds of domestic physical ground water detector in China, one is the nuclear magnetic resonance ground water detector, the price is more expensive, one is commonly used natural electric field ground water detector, the price is pro-people, is the helper of well drilling users, for everyone to solve the problem of dry eye a commonly used equipment. The ground water detector is what we usually call the ground water detector for well drilling. The instrument itself analyzes the subsurface structure, the variable layer fragmentation zone, and the amount of water cannot be seen, but through the subsurface structure to analyze the water conditions, well drilling users know that the variable layer is the place with the best water conditions, and then combined with personal geological experience and local geological conditions lithological agreement analysis to determine the amount of water.
There are not many brands of domestic ground water detector, but the water detector of Hunan Puqi Research Institute of Geological Exploration Equipment is a one-key instrument, which is suitable for the majority of well drilling users.
Hunan pqwt research institute GT series automatic map ground water detector is based on the earth electromagnetic field as the field source, based on the difference in electrical conductivity of different underground geological structures, by measuring the law of change of electric field components of different frequencies, to study the geological structure and changes, scientific search for groundwater resources geological structure changes through the curve graph real-time display. A simple one-click operation automatically generates geological profiles, getting rid of the tedious computer mapping. The instrument is widely used in different terrains such as plains, hills, mountains, plateaus and basins to quickly analyze the changes of geological structure and determine the well location, water-bearing layer and depth of water-bearing layer.
