The housekeeper was organizing people to dig wells, and Yang Heng also started his construction work.

The job of digging a well is very simple. First, dig out a place with a diameter of about four feet. When the depth reaches seven or eight feet, Yang Heng will put down the cement pipe specially made by Yang Heng. The cement pipe has a diameter of four feet. Now Yang Heng still feels that it is better to do these things. It is more than three feet high. In order to be strong, Yang Heng also specially thickened the thickness of the cement pipe, which is more than three inches thick. Once the cement pipe starts to go in, a small one can be excavated in the cement pipe. Someone digs it out with a basket handle.

The soil that came was pulled up. For the safety of the person who dug the well below, he also put a bamboo-woven safety helmet on him. In this way, even if the head of the basket falls off and hits it on his head, it doesn't matter much. Yang Heng even set up some copper nails that can hang things around the cement pipe wall. When it reaches a certain height, a few ropes can be hung on the copper nails, leaving only a hole that can make the head of the basket fall off, so that the head of the basket falls off with the soil full of the basket, and will not cause any damage to the people below.

The rope puller is not pulled directly by manual. Yang Heng designed a large wheel, so that several people need to cooperate to dig the well. Some wheels are shaking, some shaking, some surveillance, some shaking, some shaking, and some shaking, and some shaking, and some shaking, and naturally some placing cement pipes down. After the people below dug a section, the cement pipe will fall due to its own weight. If it falls to a certain depth, a piece of cement pipe will be added. Unless there is an overall landslide, there will be no danger.

Yes, Yang Heng used several copper mirrors to reflect sunlight for lighting, so that the oxygen would not be burned by burning torches or other things. Also, in order to ensure that there is enough oxygen below, a small oil lamp is still necessary. Once the lamp goes out naturally, people should quickly sit in a special basket and pull it up. Then they will fill it in, or pump it out until the environment inside is suitable for the people and will excavate again.

If there will be accidents under such strict protection, it can only be said that God will do so.

What he wants to prepare? What he needs to prepare is to build a well head for a water press well, and some water pipes. This well head is easy to make, but the water pipes are difficult to make. The well head only needs to be made into a sand mold and then poured in molten iron. After it is made, some people will polish it carefully. One well head will come out. Some joint constructions are made because Yang Heng has made copper bolts and copper nuts in front, so that there is a mold, and it is easy to make some steel bolts and nuts, but it only needs quenching.

The pistons inside the well head require rubber products, so what should I do? Naturally, I still use some felt to make them. This is why Yang Heng polished the inside of the well head very smoothly. This polishing is divided into many steps, first of all, rough polishing. Then there is a play polishing, and finally fine polishing is used with linen, but a lot of linen is wasted, which is not affordable for ordinary people.

But the most difficult thing is to make the suction pipe, what to use as the suction pipe. Yang Heng considered the bamboo pole, but the bamboo pole would rot after being used for a long time, and the joints were difficult to seal, or made with animal skin and connected with glue. The water pipe made in this way can be OK, but it is too soft and not suitable to be a suction pipe. Even the water pipe is not suitable for use, and the cost is too high.

Finally, Yang Heng decided to use iron pipes as suction pipes, applying a layer of glue on the inside and outside to prevent rust, prevent air leakage, and even connect. However, this connection method is a bit complicated. The cement pipes that were lowered in advance and the cement pipes that were not lowered in, all holes were required to fix the iron water pipes. The fixing was also fixed with copper nails and copper wires so that they would not rust.

Finally, when the well began to come out, all the configurations of the pressurized well were completed.

Some people say, why don’t you use a wheel to lift water, but use a water press. There is a reason here, that is, after the water level underground is too deep, how to pump water upwards. One bucket at a time is not possible. If you can raise it with a bucket and keep up with the well, the well will not be of much use. Not to mention a severe drought, there will be no water in a small drought. However, these five-inch diameter pipelines, large-diameter water presses, and several strong laborers will press water together. The following is to introduce the large amount of water, which can be further improved.

The digging was a little deeper, but the setting of the water pipe still wastes a lot of Yang Heng's energy. Before the well is dug, it is impossible to fix the water pipe on the well wall. Only by fixing it with other methods are used first. The well head of the water pressed above and the water pipe rises and falls together. In this way, there are a lot of insurance equipment in the underground facilities. Even the person who digs the well must know how to swim. At least he must be able to hold water. Otherwise, once a large amount of spring water comes, he will be soaked in the water and then slowly pulled up by the people above.

"It's out of the water," the person who observed the underground was shouting loudly. He really wanted to come whatever he wanted. When he was about to get nearly fifteen pipes, a very strong source of water appeared. The people underground quickly fell into the underground. Even if they wanted to float up, they were not that fast. Fortunately, Yang Heng was prepared, "Hurry, hurry up, pull the rope and pull the rope in his waist." At this time, there was no way. He didn't know if he had grabbed other ropes, so he could only pull the emergency rope in his waist. This rope was tied to the waist and tied a line on his chest. Then the rope would be pulled up with about half a foot below his neck as the focus point. This pull, he would not be frustrated in the underground, and would not be damaged.

"Ah..., I'm suffocating." Finally, a shout came from the well. It seemed that he had come out of the water. "Pull it, keep pulling it. It seems that he has nothing to do. Come and prepare ginger soup, some clothes and quilts, etc.." Why prepare these? Under the well, although the temperature is not very high, it is still more than ten degrees, nearly twenty degrees. Once it appears on it, it will look more than twenty degrees below zero. If someone dies because of digging a well, Yang Heng will definitely regret it for the rest of his life. This well can actually be dug or not, just from

The water diversion in the river outside will be very fast and safe, and it will not waste so much money. Yang Heng's idea of ​​digging this well is that there will be no mineral water suitable for brewing wine. You must know that in this era, some natural things in this place have not been destroyed, and the mineral water may be very large. Moreover, Yang Heng has also observed the surrounding mountains. Judging from the direction of the mountains, there will definitely be water in the mountains below. In this way, although these water is not mineral water, the water quality is incomparable to the river water.

Sure enough, from the situation of water coming out of the well, this is the water from the mountains, and it was dug into the water veins.

Sure enough, "I was down there and couldn't dig anymore, and there was a sound. It seemed that I had encountered a stone. As soon as I tried so hard, I felt a stone loose. It seemed that it was a water line. Then, the water burst out and I was drowned under the water. Fortunately, I would hold water, otherwise my life would be gone..."

The man who dug the well was surrounding the quilt, roasting the fire, and bragging the cows. A group of people were around him, listening to him bragging.

"Okay, don't chat anymore, let's have a rest, hurry up and finish the matter." The housekeeper started pouring cold water on him, so people scattered.

At this time, the water level was fixed at the position where there were six pipes from the wellhead, but it was slightly lower than the river surface in the distance.

"You all put away this water press, and the pipes are also collected. This place is not available." Why should I put it away? This is specially designed for drilling wells. The water pipes used are much smaller than the well head. The diameter of the pipes is directly reduced to about one and a half to two inches. The well head is only as thick as the previous water pipes. In this way, one person can use water pressing, and this speed is much faster than lifting water with a pulley. Similarly, Yang Heng did not set the pipe not far below the water surface, but made people dive into the well and fixed it on the well wall many times before it was completed.
