Water well drill pipe explains some common sense problems of drilling
Well drilling is 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 pipe summarizes many methods based on experience and has been used until now.
To make the right judgment, you must first understand the basic elements of diving:
1. Diving flow direction: Diving moves downward from the high to the low of the diving level under the action of gravity, so the diving flow direction is perpendicular to the diving and other water lines and points to the short line with the small diving level value from the large diving level value.
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 the diving water. In general, the higher the terrain, the deeper the dive's burial.
3. Water replenishment relationship between phreatic water and surface water (such as river water): Compared with graphic observation, if the contour lines on the water level map are as large as phreatic water, the direction of the value is convex, indicating that the river water level is lower than the phreatic water level, and the phreatic water supplies the river; on the contrary, the river water level is higher than the phreatic water level, and the river water supplies the phreatic water. Water well drill pipe can be used to determine recharge relationships by diving near surface water. This method is to use the water level value of 0 to 7d0 as the water level line of the water level direction. 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. According to the characteristics of the contour and related knowledge, the contour is raised in the direction of the large value, indicating that the value of the ground is very small, that is, the ground is the catchment area. Of these four sites, two have the largest curvature, indicating that there is a large change here, and the phreatic water flows to the four places at 34, so the two sites have the most abundant groundwater resources.
