Digging a well, how do you know there is water underground? Simple and concrete methods.

1, according to the principle of "anticline"; It is difficult for faults to produce water. When the fault plane is fragile and cracked, water will seep down. Naturally, no matter how good the well is, it will not upwell. The anticline is convex, and the middle rock is hard, which is higher than the average thickness. It is also futile to dig wells in such a place.

2. The vegetation on the "anticline" mountain is sparse and the moss vegetation is generally rich. Syncline is concave. Obviously, water permeates the bottom of the rock, and the effect of drilling wells from above is very good, which not only reduces the workload, but also preserves the water source.

1. According to the buried distribution of groundwater and the lithologic structure of aquifer, human beings have created various well types.

2. People in China have been using barrel wells for a long time. Most of them have a diameter of 1 ~ 2 meters and a depth of several meters to 20 ~ 30 meters. During construction, people can directly enter the shaft to dig earthwork. This kind of well is only suitable for exploiting shallow groundwater.

3. In order to exploit deep groundwater, tube wells with small diameter (several centimeters to tens of centimeters) and considerable depth (several tens to hundreds of meters) have been developed. Pipeline drilling requires special drilling machinery and complex technology. As early as 250 BC, in today's Sichuan Province of China, a large number of wells with a depth of tens of meters or even hundreds of meters were dug in hard rocks to exploit underground brine to cook salt.

4. After drilling a well to expose the confined aquifer containing salt water, groundwater often flows out from the well itself. This kind of well is artesian well. China Sichuan Ziliujing (now Zigong City) got its name from this. In modern countries, tube wells are mainly used to mine groundwater, power rigs are used to drill wells, and various pumps are used as water lifting tools.

5. Before 1949, only a few cities in China had several tube wells, and only a few wells were electrified to lift water. By 1980, 2.2 million wells have been electrified to lift water, which are widely used for water supply in industrial and mining towns and agricultural irrigation.

Farmers blow out 4 meters high mountain spring water.

1, Xinhuanet Shijiazhuang July 17 (Zuocheng Zhang, Zhang) July 14, a farmer in Jiulongtan Scenic Area, Xinglong Town, Xinglong County, Hebei Province accidentally sprayed a water column of mountain spring water more than 4 meters high.

2. Due to the drought, Dong, a villager in Sara Village of Xinglong Town, hired a professional well digger in the county to dig wells. "The original plan was to hit 50 meters deep, but it could hit 30 meters, and it was out of the water. When it hit 40 meters, the drill began to spray water before it was withdrawn. " Dong said to him.

3. This well is located near the parking lot of Jiulongtan Scenic Area in Qingsongling Grand Canyon, with a depth of 46.5 meters and a cost of more than 4,000 yuan. At present, not only the water gushes out a mountain spring water column more than 4 meters high, but also there are many springs around. The water quality is cool and sweet, and local villagers and tourists compete to drink it.

4. Xu Zhixue, head of the drilling team, said: "It may be caused by water veins, large underground water storage and high pressure."

Zheng Zheng, the general manager of the scenic spot, is talking with Dong about building a scenic spot, a water park and an ornamental fish garden here.

6. Qingsongling Grand Canyon Jiulongtan Scenic Area is a national AAA-level scenic spot, located at 15km southwest of the county, with a valley-like landform. During the orogeny1.400 million years ago, a fantastic canyon with knives and axes was formed, and the scenery was mysterious and attractive.
