How did the wells that are common in rural areas find out that there is water underneath in the past

The most important process for drilling wells in rural areas is to select the right surface water. After all, surface water is water hidden in the gaps between the rock formations below the road surface, which cannot be seen by the human eye, and the ancient people did not have testing equipment, even with the current scientific concept of development, it is unlikely that the surface water source will be selected 100% accurately. Therefore, in the past, when everyone used their work experience to find water to drill wells, there were often misjudgments, turning around and turning around, making a dry well with no water to use, or exploring a salty deep water well, which could not be taken.

We need to understand that there is no doubt that there is water stored in the ground, and the key to the intensity of the surface water layer lies in the elevation of the ground, and in addition, it is to see if there is a fixed water resource nearby. For example, in some low-lying areas, the groundwater is particularly shallow, and in some areas near the sea, the water line is also very shallow. For example, in some areas of Tianjin, you immediately dig a hole in the ground with a shovel, and water will gradually seep out from below.

But in the same way, there are many mosquitoes in such an area, and the water level is shallow, so it is wet and cold, and it is very easy to attract mosquitoes. This kind of location close to the sea is an individual case, and in such an area, the water that is dug up immediately may not be edible, and because the sea seeps in immediately, sometimes it is salty, and the soil layer cannot be reasonably considered.

It seems that some plains, most of them do not need to be surveyed, and it is enough to select an area to excavate the foundation pit immediately, and most of the underground is water, but sometimes it is a problem of the water line. We have to understand that this surface water is not the same as other minerals, and it is also different from **, this food must be produced for a period of time, and there must be corresponding chemicals. Water is the case, water is a large circulation system of the whole process, rainy days of water infiltration, used water penetration, this is through the soil layer after the consideration of the surface water.

There is also a small way of drilling wells to find water, after opening the store and selecting the site, put some soybeans in the suitable position, and then use a small bowl to buckle the soybeans to maintain the natural environment of tightness, and after staying overnight, lift the bowl to see what changes the soybeans have, if the soybeans have not changed, <>

It means that there is less water vapor on the ground, and there is no idealization of groundwater and water resourcesIt is not suitable to dig wells here, and the soybean has a significant expansion change, which means that the surface water and gas are very abundant, and the water resources are also very satisfied, so it can be thoroughly excavated. It is very demanding to drill and explore the well location. With more than ten years of work experience, the driller knows that there is a strong water there, and there is no water there.

There are also many oral decisions, all of which are the accumulation and aggregation of work experience.

In rural areas, there are generally two types of well drilling. One is called a machine well, and the other is called a water well.

The well is used to water grain, cotton, melons and fruits, and vegetables in the field. In the past, irrigation was carried out by canals, and the well site was generally selected on a higher ground. In this way, the whole field can be watered.

At present, it is generally sprinkler irrigation and buried pipelines, and the well site is generally selected in the middle of a field. In this way, there is a rational application of the layout of sprinkler irrigation and buried answers. The shaft is generally 30 to 60 meters shallow.

Wells are drinking water for people and animals. 100 to 200 meters deep. It is closer to the village, and the well generally chooses the heavy side of the village, and there is absolutely no choice of the light side of the village.

The vast land of Yicun is flat and stable. Second, the well site should generally avoid graves and sewage sources. The site of the three wells should be selected at the place where the earth gas is outlet, and only in this way can the water in the well be clear, pure and sweet.

The descendants live in the Qinchuan Great Plain, and there must be water underground. However, it is necessary to choose the depth of the well site according to the use of the well.

Generally, the underground is detected by instruments, and the water level is found before drilling a well.

It can be surveyed by digging a hole hole, digging a one-meter-deep pit, and if the water comes out the next day, it means that there is water underneath.

Hello dear<>

1. How to know that there is water in the ground when digging a well 1. According to an important principle of "back and oblique"; Faults are generally difficult to obtain water, the fault plane is fragile and cracked, water will seep down, naturally, no matter how the well is drilled, it will not upwell; The "anticline" is "convex", and the rock in the middle is hard and above average thickness, and it is futile to dig a well in such a location. 2. If the vegetation of the "anticline" mountain is relatively sparse, the vegetation of mosses will generally be relatively rich.

The "oblique" is of the "concave" type, obviously, the water seeps into the bottom of the rock, and the effect of drilling a well from above is better, not only the workload is less, but also the water source is continuous. 1. If you dig a well by yourself, you can see that a lot of water suddenly comes out, and it is continuous, that is, the water is out; 2. If the machine drills a well, when drilling the well, the mud will come out of the well pipe, if there is water below, the mud will decrease, the water will increase, and sometimes it will become muddy water, indicating that the water has been hit, if there has been more mud, it means that the water has not been hit, only to live and play, it is difficult to hit the machine, and then decide whether to change a place. Wells, engineering structures mainly used to extract groundwater.

It can be vertical, oblique and a combination of different directions, but it is generally vertical, which can be used for domestic water irrigation, and can also be used to dodge, hide or store some things, etc., and the above is my reply to you, if you think my reply is good, please move your fingers to give me a five-element like, oh <>

When digging wells in rural areas, there are three main ways to find out that there is water underneathOne is based on experience, the second is to judge by digging holes, and the third is to look for places where spring water is bubbling up.

First, based on experience

Although the success rate of empirical exploration of groundwater resources is low, it is indeed a method used by some rural areas with relatively difficult conditions to find water sources before drilling wells. This is because one can tell if there is water in the ground by some reference objects on the ground, and there is some truth to this judgment. As a simple example, there are usually more abundant water resources near lush trees, because trees cannot grow without water, so the more lush the trees, the more abundant the groundwater resources near them.

In the same way, ponds, rivers, and low-lying areas that are prone to water accumulation are also the basis for people to judge whether they are suitable for drilling wells based on experience.

Second, make a judgment by digging holes

Digging holes is a common way to find groundwater in rural areasTo put it simply, dig a one-meter-deep eye pit in a few promising locations, and wait one to two days to see what is going on in the pit. If there is a relatively clear and odorless spring in the pit, it means that the eye pit is a very suitable location for digging a well. However, if there is too little water in the pit, the water is turbid, or there are other smells coming from the pit, it means that the pit is not suitable for drilling wells.

It can be said that although this method is more time-consuming, it has a higher success rate than using experience to determine the location of the well, and it is a very practical method for villages that need to drill several wells at the same time, which can speed up the progress of the project to a certain extent.

3. Look for a place where spring water is bubbling up

In most cases,If there is a spring in a certain place, it means that there is a very rich underground water resource in that place。In such a situation, if people dig down, there is a high probability that they can directly complete the well drilling project. In other words, it is a survey method that does not require much effort, but it depends on luck.

In general, there are three main ways to survey groundwater resources when drilling wells in rural areas, one is based on experience, the second is to judge by digging holes, and the third is to look for places where spring water is bubbling up.

Wells in the plain area do not need to be explored, because the water level is very shallow, you can directly excavate to see the water, if it is at a high altitude, you need to rely on experience, such as comparing multiple places, the most humid place may have water, and the early thawing time may also have water, and it is most appropriate to use machinery.

If you wake up in the morning and find water droplets or mist in the bowl, it means that there is water under the well, and it will be identified according to the surrounding environment, and if the surrounding plants are very lush and there are rivers around, it means that there must be water resources underground.

It is mainly based on geographical conditions to choose a place close to the water source to carry out excavation and investigation, and China's well detection technology is very advantageous, and the technology is advanced; Through the analysis of the area, and then the corresponding excavation detection, the main thing should be to observe the geological conditions, select some places close to the water source for investigation, and then excavate, after reaching a certain depth, there will be the performance of the water source.

Mainly by observing the terrain, people in rural areas generally have a certain amount of experience, and they will also find low-lying places to dig wells.

The most important thing when drilling a well is to determine the place where the well is drilled, and to determine this location, it is necessary to determine the location of the well by observing the location of the well, determining the local geographical environment and the changes of the four seasons. Many people are concerned that if there is no water, it will also cost money, so digging a well also requires a lot of wisdom.

If it's summer, you need to judge where the sun has been exposed, usually the temperature is relatively high, but if the bottom of the place should be relatively humid, its temperature will be relatively low compared to the temperature, so there is usually water underneath the place.

If the weather is cold, it can be judged that the temperature in some areas is below freezing, and if you find that some places near your home freeze later than others, and if there is frost after freezing, then there is a greater possibility that there is a water source underground.

Benefits of well water:

The well water is non-toxic because of Ganping, and the ancients often used it to stop bleeding. If the gold sore bleeds, the dog bite bleeds, and the bleeding does not stop, they are all washed with well water. In addition, nausea, hot diarrhea, hot shower, etc. are also taken with well water** or well water decoction.

It's not just well water that gives people a feeling of being warm in winter and cool in summer. It's the groundwater, the caves, the cellars, it's all like this. Taking advantage of this, fruits and vegetables can be stored in the cellar in the winter to prevent frost damage, and in the summer to prevent corrosion.

Because rocks have voids, water can exist between these voids. After rain, the water can seep into the ground, and the surface water seeps into the ground along the rock void under the action of gravity, becoming surface water, which is stored in the rock void, and if the gap is very developed, the water can flow freely in the rock to form a diving surface. Drilling a well is to dig a deep channel from the surface, directly below the diving surface, because the water can circulate, it will flow into the well, and then it can be pumped with a pump.

Beneath the surface of our earth, there is water in many areas, which is called groundwater. The spring water in the mountains is the groundwater that flows out of a damaged area. If an area has abundant groundwater, if you dig a little deeper, the groundwater will gush out, which can become a well.

If the groundwater is not so abundant, dig a little deeper, and there will be water coming out.

Ordinary people dig their own wells as long as they dig to the place where water is leaking out. Then use bricks to form a garden, put some sand or stones at the bottom, and the well is dug, and when it is just dug it is mud water, the water is very clear after a few days. If it is a unit or an enterprise, then when digging a well, it is necessary to dig the aquifer. Otherwise, there will not be enough water. This is where a professional comes in to find the location of the well. When the well is first dug and the water is mixed, the mixed water is pumped out with a pump. And the water of the well was cleared.

In the past, in the countryside, many people wouldUtilizationNatural environmentcharacteristics and growth characteristics of some plants to find an adequate source of groundwater, such as some wild plants in other places have thick roots and deep root systems. The soil at the roots of the tree is moist and moist, which is where the groundwater is abundantThis is the crystallization of the wisdom of the past, and water is easily obtained through plant mediaThere is also the observation of where the ground is often wet, which freezes later in winter than other places, and frosts and thaws earlier than other places, which is also where groundwater is more abundant.

The common wells in the countryside did not need to be surveyed in the plains in the past, just choose a place to dig them, and there was basically water in the ground, but it was just a matter of whether the water was shallow or deep. The depth of the water level is also directly related to the local environment and weather, due to the excessive water consumption in recent years, the shallow water stored underground is not enough, and the weather is too dry, the water level is too dry, people can only choose to dig the well deeper to have well water. Many rural wells are dug using methods to observe topographic conditions, mountain ranges, confluences and trendsInflection pointThese are places where water sources tend to gather, and when a well is drilled in such a place, it is easier to get well water, because the water seeping from the top has already flowed out from here, and a lot of it seeps into the ground.

The water in the well, also known as groundwater, is different from other minerals in that the formation of minerals takes a long time to evolve and requires specific substances. This is not the case with water, which is a major cyclic process, when it rains, rainwater seeps in, used water seeps in, they are filtered by the soil layer and eventually form groundwater. Therefore, most people in rural areas will choose to be in low-lying areas, because such terrain is easy to accumulate water, for example, when it rains, water will slowly flow to this place and seep into the ground, such places will accumulate groundwater, and the easier it is to dig out the well water.

Although it is relatively simple to drill a well, it does not mean that the water quality can be consumed by humans, in the past, there was a very simple and ingenious way to check the water quality by putting a few fish in the water, and if the fish can grow well, the surface water quality can be safe to drink.
