Where to drill a well more reliable? What are the precautions for water source well drilling? Winter individual areas will appear now a big drought phenomenon, many places began to increase the well drilling project, but due to technical and other conditions, some water well source will also have some hidden problems. In particular, the construction of water well sources, some farmers do not use the correct construction methods, so that the rate of completion of the well decreases, the service life of the well is reduced, in order to change this situation and improve the construction of water wells, farmers are recommended in the future construction of water wells should pay attention to the following construction points for farmers to build their own large mouth well construction.
Choose the appropriate well type water source well type is divided into: deep wells, large mouth wells, counterpart pumping type wells and small diameter tube wells. In areas where deep groundwater is abundant, deep wells are suitable. In areas where shallow groundwater is abundant, large mouth wells, counter-pumping wells or small diameter tubular wells are suitable.
The layout of the well holes should be based on the actual local hydrogeological conditions. In areas where shallow groundwater is not abundant, shallow wells must not be blindly drilled; in areas where shallow groundwater is more abundant, shallow wells built by farmers are suitable, but the layout of boreholes should not be too dense to avoid mutual influence between neighboring water wells.
After configuring a suitable pump into a well, you should measure the static and dynamic 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 required, and the flow rate of the pump is not allowed to exceed the water flow rate of the well, and purchase the appropriate pump for the well from the above two conditions.
There are two methods of construction of large mouth wells using the correct construction method:
First, the large trenching method, manual excavation or blasting construction;
The second is the sinkhole method, which is constructed with or without drainage. Which method is more suitable to be adopted is determined according to the local geological conditions. The construction of the counter-pumping type, generally using mechanical and manual lifting hammer two methods, the use of gravity of the hammer will be suction pipe directly into the ground. The counter-pumping type well accounts for a large proportion of existing wells, which is economical and practical, and is chosen by farmers more often.
PQWT water detector is used to find water by using natural electric field as the field source, based on the difference of electrical properties of underground rocks and ores (groundwater), after measuring the natural earth's electromagnetic field in several different frequencies of the electromagnetic field to study the electric field and different geological bodies to produce anomalies to achieve the purpose of finding underground water sources.
