Chapter 90: Successful Well Drilling

When Lu Qi and Liu Bensheng saw Zhang Zhimu arrive, they all came around.

Zhang Zhimu asked: "Look at your sad faces, what are the difficulties, tell me about it." Lu Qi said: "We are experimenting with this spinning machine, and it is used well in the south, but I don't know why, it can't be done here." Zhang Zhimu looked at it and asked, "What's the problem?" Lu Qi said: "Now the imitation coarse yarn is no problem, but the imitation fine point is easy to break." There's nothing we can do about it. Zhang Zhimu was happy when he heard it, and said: "It's not your fault, it's because the air in the north is not as humid as in the south." The tension of the yarn is not enough, so the yarn that imitates too fine is easy to break. In order to be able to imitate the yarn as fine as in the south, the workshop needs to be sprayed with water and a certain temperature must be maintained. However, the conditions are not ripe now. You don't have to worry too much about that. Lu Qi and the others woke up like a dream, but they thought it was strange, this Mr. Zhang knew everything.

Zhang Zhimu saw that everyone was finally relieved, and asked, "Do any of you know about Huo Huanbu?" "Several people said they had heard of it, but they hadn't seen it. Zhang Zhimu said: "Then you will start to weave a kind of fire raccoon cloth for me." One-third cotton and two-thirds asbestos are spun into yarn, which is then woven into cloth. ”

In fact, the fire cloth is a cloth spun from asbestos fibers, if this kind of cloth is dirty, put it on the fire and burn it, and then shake it, it will be as white as snow again. That's why people call it fire cloth. Very early, the ancient Chinese began to use asbestos fiber weaving. However, blended cloth should not be burned with fire. Because the longitudinal tensile force of asbestos fiber is very strong, but the transverse shear force is poor, and it is easy to break, and this deficiency can be made up for by blending cotton with it.

It turned out that Zhang Zhimu saw that the workers in front of the iron furnace were often burned by the flying iron flowers, and the clothes they were wearing were burned one by one. Not without protection. Zhang Zhimu wanted Lu Qi to weave asbestos blended fabrics and then make asbestos overalls.

Liu Bensheng said: "The imitation line is thicker. Zhang Zhimu said that it was okay, and it was coarse. It's not enough to make protective clothing that is too thin.

In order to show the importance of these cavalrymen, Zhang Zhimu and Chen Yufeng came to visit them. In the camp, pigs and sheep were slaughtered, and as in the New Year, because there were not so many tables at once, rows of tables were temporarily built with wooden planks, and the meat and vegetables were all placed, and the wine was also brought up one by one. These people who have just joined Yaogang, on the way to Yaogang, have been muttering in their hearts, this time they have defected to others, and they don't know how they treat themselves. I didn't expect that as soon as I arrived at the camp, all the wine and meat would be on the table. All of them are flattered.

Zhang Zhimu's deeply rooted speech made the newcomers put their hearts in their stomachs and felt that this thing had really found a home. He also asked people to send the pocket money to everyone on the spot. Zhang Zhimu told the new employee that he could go to the city under the leadership of the old employee in the future. There was an uproar at the bottom, and they all wanted to go out on the street to see if they had money in their pockets. With money, you have enough confidence to go to the street. Then comes a drink. Yan Boju found a few bosom friends here, and there are several people here who are very familiar with horses, they all grew up with horses on the grassland, and they know even more about horses than they know about people.

Zhang Zhimu told Liu Yun that the personnel should be reorganized according to the predetermined plan as soon as possible, and the 30 cavalry we brought back would be the core of this team in the future.

Then Zhang Zhimu and Liu Chenghuang had a very serious conversation. After this talk, Zhang Zhimu had a further understanding of Liu Chenghuang. This person's ability may not be worse than Fan Chengkun. Zhang Zhimu instructed him to lead this team well. To these people, we must pay equal attention to grace and might. You have no authority, and they will not obey you; You have no grace, and they disrespect you. This team is the seed of our future development, we must pay attention to cultivating talents, but also to discover talents. Those who have the ability to stand out must dare to reuse. To be good at communicating with the brothers, it is important to know what everyone thinks. As a leader, try to think things ahead. In addition, this is a team of five or six hundred people, and it is not yet possible to completely train out of production. There are tasks to be shared on the company's side, and we are all employees now, and we can't set up a full-time army yet.

Liu Chenghuang's suggestion made Zhang Zhimu look at him differently.

Liu Chenghuang said: "These five or six hundred people can't always stay here, and after a period of training, everyone will be familiar with it." It is better to go out to practice and train troops in actual combat, there are still a few bandits between us and Hukou, it is better to take them for training and train them, and exterminate them. ”

When Zhang Zhimu heard that this was a good idea, he said: "When the soldiers are trained, they will do as you say." In that case, I should equip you with some muskets as soon as possible, I thought that there would be no hurry, and when our good steel is refined, we will make rifles and then ration them to you. Now it seems that we can't wait. Liu Chenghuang also said: "It's better to be early and let them practice riding horses and shooting guns." ”

Zhang Zhimu said: "You have a more important task, that is, to study the tactics of the Mongolian cavalry, one is to use it for me, and the other is to have a way to deal with it. Also, I will send you an assistant with a good writing to sort out the summary things. In the future, if we open a military school, these are all teaching materials. "In fact, the person assigned to him was a person chosen by Li Zhi.

After talking to Zhang Zhimu, Liu Chenghuang was very excited, he didn't expect that he was so thoughtful about the problem in charge, he was really meticulous, and he was also far-sighted and extraordinary. This is a man who has a big career to do. Liu Chenghuang also felt that he had a direction to struggle, and this time he could finally display his skills.

When Zhang Zhimu returned to his post, Li Yunhe was looking for him and asked him to see the results of their experiments.

When he came to the workshop, Li Yunhe showed Zhang Zhimu the inner and outer screw buckles of different pipe diameters. Zhang Zhimu saw that the threads processed with plate teeth were dried very evenly, and it seemed that he had put a lot of effort into it, and Zhang Zhimu personally used pipe pliers to jam the pipe joints and connect the two pipes together with joints. Zhang Zhimu said: "In the future, when the heating is really installed, some hemp silk and lacquer should be put in this thread, so that there will be no leakage." ”

Li Yunhe said: "It's just that the switches we make are always not closed tightly, and there are still some water leaks." "You can make a mat out of oiled cowhide and put it in the switch, so it's much better." When the women finished their clothes and quilts, let them pick some rubber straw, and the mats made of rubber would last longer. The small air release valve is made of copper, which is easy to process and is tightly made. Zhang Zhimu said.

After a period of hard work, Li Yunhe began to install the heating according to the drawings. Of course, the first one is to install heating for Zhang Zhimu's small building. But when installing the heating, he smashed all the holes in the good walls, which made Huang Yukun feel distressed. Huang Yukun said: "This is a new building and it was smashed. Zhang Zhimu said: "When you wait until winter, you will feel that this time it is worth smashing." When it's warm in the house, you'll be fine without clothes. Huang Yukun angrily pinched Zhang Zhimu again.

Li Yunhe has one work that has not progressed, that is, the heat-resistant paint has not been found. If you use paint that is not heat-resistant, you are afraid that as soon as the heating is hot, it will melt. Zhang Zhimu gave a suggestion, you can use a variety of lacquers, mixed to try. Some can be paired with tung oil, etc., and get a few more formulas to see. The result is really good, there are two formulas of paint brushed on the tube, and after drying, it is okay to scald it with boiling water. Zhang Zhimu said: "This formula should be kept secret, and it will make a lot of money in the future." ”

Wait until all the room heating is installed. Zhang Zhimu asked Li Yunhe to lead the people and brush all the pipes and radiators with paint. When the paint was dry, the pipes outside the room were wrapped with straw ropes, and the outside of the straw ropes was covered with a thick layer of mud made of lime and asbestos; Before the lime and asbestos mud were dry, another layer of straw rope was wrapped. The underground heating ducts outside the room are all made of bricks, and Lu Chengxiang, who watched it, inhaled and felt a little too loser. But Zhang Zhimu insisted on this, and it naturally made sense for Lu Chengxiang to want to be in charge, so he didn't say anything. The heating duct is covered with prefabricated cement slabs. This, in turn, requires a lot of cement and rebar.

Zhang Zhimu knew that it would cost a lot of money, but he did it himself, firstly, to make everyone more comfortable in winter, but also to make a model for outsiders. He knew that this model would soon become popular in Shanxi and even the entire north. At that point, the business opportunities are limitless. In particular, he deliberately installed copper radiators in his building, which will also be a model for those big families to learn. Those are some people who are not afraid to spend money.

Li Yunhe is installing heating here, and the work of digging wells over there is also going on to a more and more difficult stage. Because the further down you dig, the slower you move up. They all lift the soil up through the wheels, and although the wheels are pulled by oxen, they are still very slow.

Zhang Zhimu couldn't think of any better way now, so he simply didn't care, and began to dig the foundation next to the well, and he wanted to build a cement tower next to the well, which was going to install the fan.

Since these craftsmen have worked in the three-story building, they have an understanding of the cement pouring process. After Zhang Zhimu introduced them according to the drawings, these people said: "Okay, Mr. Zhang, this is much simpler than that small building, we can do it without you being present." Zhang Zhimu heard that these people were really quick to get started, so he didn't bother about it.

He asked Lu Qi to send him two carpenters with better skills. Zhang Zhimu relied on his memory to sharpen a small blade with three blades according to the shape of the blades on the wind turbine he had done in his previous life. Then use a small stick to pierce the shaft of the blade, blow with your mouth, and the small blade suddenly turns fast. Zhang Zhimu said to the two carpenters, "The task of the two of you is to make big blades like this." A single blade should be four feet and five feet long, and a total of three blades should be made. You should first find three hardwood poles of the same thickness and a little more than four feet and five feet long, cut the wooden poles to the same thickness with a knife, and then use the wood to make a leaf and nail or stick them to the wooden poles. The two carpenters began to work on the three blades.

Here, Lu Qi led people to study the drawings of the bevel gears drawn by Zhang Zhimu. Before they could figure it out for a while, Zhang Zhimu came over to explain it to them and told them about this drawing of a "bevel gear". This bevel gear transmits power to the vertical shaft of the power shaft. I want to use it to drive the fan blades, the rotating power of the axis parallel to the ground is transmitted to the axis perpendicular to the ground, the axis perpendicular to the ground transmits the power of the fan to the ground, and there is a pair of bevel gears at the lower end of the vertical axis, which converts the power of the vertical axis into horizontal power, and uses this power to drive the waterwheel, and you can lift water. The so-called "proportional bevel gear" means that the two gears have the same number of teeth, the speed of the active shaft and the passive shaft are the same, and the torque transmitted is the same. Moreover, such bevel gears can do exactly the same, reducing the complexity of processing. With two pairs of such bevel gears, the power of the wind turbine blades is transmitted to the ground. This power can be used for both lifting water and other purposes, and it is also possible to drive the lathe when the wind is strong. Of course, we will also study gears with different transmission ratios in the future. Now I want to make two pairs of four of these gears at once, and I think it's better to make two things out of wood first, and it's clear in one stroke. Since there are now lathes, all the parts that can be processed by lathes are processed by lathes, and other gear teeth and cogs are made by hand. After two days of hard work. Two bevel gears are made, compared to the measurement, it is OK, although the accuracy is not too high, but it can be used as a power transmission. Let Li Yunhe hurry up to make a wooden mold on this basis, and the wooden mold should set aside a little processing amount. Now there are several things with relatively high accuracy requirements, which are thrust bearings and two rolling bearings. It is unrealistic to make balls under existing conditions, and thrust bearings have to make thrust cylindrical roller bearings, because the rollers can be cut with a machined steel rod, so that the consistency of the rollers can be guaranteed. Due to the large diameter of this bearing, it is not possible to achieve high accuracy under the existing conditions, but in the end the rolling friction is much smaller than the sliding friction directly on the shaft. This thrust bearing is placed on the cement tower column and directly sits on the bearing cast from cement, which is directly used to support the windmill, which can not only make the windmill rotate with the push of the rudder, but also fix the windmill with the inner diameter of the bearing. The vertical propeller shaft can also pass through the inner diameter of the bearing to transfer the power of the vane shaft.

Rolling bearings are a little less difficult than thrust bearings, but when installing, you need to be careful. Zhang Zhimu told Li Yunhe that all bearings should be smeared with butter after installation, and oil seals should be installed outside, otherwise the mud and dust in the bearings will greatly affect the life of the bearings.

This windmill uses side deviation to regulate speed. The rudder surface of this windmill rudder is not perpendicular to the ground, it has an angle with the ground, and it is not fixed, there is a deflection slideway, when the wind reaches a certain wind speed, the rudder will be slid upwards along the lift, and this slideway will make the rudder deviate from the vertical direction of the rotation plane of the blades. In this way, the tail rudder is under the action of the wind, so that the rotation plane of the fan blade also deviates from the perpendicular direction with the wind, reduces the windward area, and also reduces the speed of the fan, so as to avoid the phenomenon of flying when the wind is too strong, and damage the windmill.

Every component of the fan is not simple, Li Yunhe and Lu Qi and others are working very hard, Zhang Zhimu knows that this is the most exercised. Once these are all broken, many things will be easier to do later.

The digging of the well over there is not going well. When the well was dug to a depth of two feet, water came out. Zhang Zhimu knew that the little water that came out at this time was useless, so he asked everyone to dig while drawing water up. When we finally reached the bottom of the stone and couldn't dig any further, the well was already more than five feet deep. The people who dug the well were disappointed, thinking that this was the end of the day, and by this time the water seeping from the side of the well was very small, and it was of no use at all. Zhang Zhimu came over and said, "Don't be discouraged, go and get the steel drill." Use a steel drill to drill three holes in the underground stone, and the holes should be deeper. ”

Two more stonemasons went down to the bottom of the well and began to punch holes with a steel sledgehammer. Zhang Zhimu on the top asked people to bring a black **, wrapped it in strips with cloth, so that it could be put into the steel brazing hole, afraid of being wet by water, and wrapped a few layers with wax paper, and the long *** was also wrapped in wax paper. After the stonemasons in the well had already made three holes, Zhang Zhimu personally went down to the bottom of the well, stuffed the three *** that had been connected into the blast hole, and carefully looked at the situation at the bottom of the well and the wall of the well, and felt very satisfied. He knew that if the bottom of the stone was blown up, the water would be very stable, because the top of the stone bottom was a loess layer, which could only seep water upwards and not rise up, and if there was a breakthrough here, the water would gush out from here under the pressure next to it. Zhang Zhimu was the last to go up to the well. Let the bamboo pipe for ventilation be lifted up first, so as not to be damaged by the explosion for a while. Let everyone hide far away, and after Zhang Zhimu personally lit the ***, he also ran away. After waiting for a long time, I heard a loud "boom" in the well, and the ground under my feet felt shaken, and a thick smoke erupted from the wellhead. After waiting for a while, Zhang Zhimu went over and looked down the well, there was still a lot of smoke under the well, and he couldn't see clearly. Zhang Zhimu asked everyone to quickly put the bamboo tube used for smoking into the well again, and used the blower to start pumping the smoke and dust in the well. After a while, the smoke and dust in the well were gone, and everyone cheered when they could see that the well was constantly bubbling up. Zhang Zhimu said: "Hurry down the well, and while drawing water outside, lay stones. Several of the stonemasons went down first, and when they reached the bottom of the well, the water was already waistless, so they hurriedly fetched water from the top of the well, and at the same time sent the stone strips into the well, and the stonemasons began to put the stone bars in the water according to the eight directions. Because these stones have been placed on the well, they are very easy to place in the well. But at this time there was still far more water coming out of the well than the water being pumped up, and soon the water was already on the shoulders of several people. Fortunately, the stone bars have been stacked on the waist, and several springboards have been put down on them, and the people in the well put the springboards on the masonry stones, so that the stonemasons stand on the gangplanks and build the stone bars. Slowly, the springboard left the water, and the stonemasons could build it calmly, and Zhang Zhimu didn't care.

It took two days to build the stone bars to the mouth of the well. At the wellhead, according to Zhang Zhimu's requirements, the stonemasons used eight large bluestone slats to bite each other to form the wellhead, and the bluestone was polished very smooth, and then around the wellhead, the flat out of the tamped place, all with the smooth stone strips paved. When laying the stone strips, the waterwheel frame made by Lu Qi and Lu Qi led people were fixed with cement.

Li Yunhe's fan parts had to wait a little longer, so Zhang Zhimu asked the liberated people to build a large pool of bricks on the west side of the well, and plastered it with cement inside and out. This pool is right at the highest point of the kiln. If the pool is filled with water and connected to the water pipe, the kiln workers can use the tap water.

Zhang Zhimu was busy working on the edge of this well, and Huang Yukun came over in a hurry. said that someone from the prince's mansion had just come to deliver a letter and asked you to see him.
