Well drillingIt's a very deep technology. The primary method of drilling is to find underground water lines. If you find the wrong place and can't get water, it's a waste of energy. Now that technology has been developed, the method of finding the groundwater level is more scientific and accurate. In the past, the experience of drillers was to find underground water lines. however,water well drill pipeA number of experience-based methods were summarized and used until now.

A phreatic hydrograph is a contour map of groundwater. To make the right judgment, you must first understand the basic elements of diving:

1.Flow direction of diving: diving moves downward from the high to the low under the action of gravity, so the flow direction of diving is perpendicular to the water level line such as diving and points to the short line with the small value of the water level from the large value of the water level.

2.Buried diving depth: Buried depth= The ground level of the diving level at a certain point, that is, the difference between the value of the contour line corresponding to a point (ground height) and its diving water. In general, the higher the terrain, the deeper the dive's burial.

3.The rehydration relationship between diving and surface water (such as river water): Compared with the graphical observation, if the contour lines on the water level map are as large as diving, the direction of the value is convex, indicating that the river water level is lower than the diving water level, and diving supplies the river water; In contrast, the river water level is higher than the diving water level, and the river water supplies diving.water well drill pipeRecharge relationships can be determined by diving near surface waters. The method is to useThe values of the diving level from 0 to 7d0 serve as the water line in the direction of the diving level. If the plumb line points to the river, the diving supply river is indicated. If the plumb line deviates from the river, it means that the river water supply is diving.

4. Selection of water well location: The well is a facility for a tubular vertical water collection project for extracting groundwater. In order to increase the amount of mining recharge and ensure the long-term balanced exploitation of water sources, water sources should be selected in areas where the maximum interception of subsurface runoff is possible, close to the source of recharge water and the land can sufficiently capture the various recharge, if the source of water is as close as possible. River banks providing groundwater, areas near underground runoff as discharge areas, etc.water well drill pipeAccording to the characteristics of the contour and related knowledge, the contour bulges in the direction of the large value, indicating that the value of the ground is very small, that is, the ground is a catchment area. Of the four sites, two had the largest curvature, indicating that there was a great deal of variation here and that the dive flow34 in four places, so two sites have the richest groundwater resources.

Mastering drilling is only conducive to the implementation of our well drilling, improving the efficiency of well drilling and saving resources!
