Chapter 249 Daming Infrastructure Crazy Demon
Relevant people are responsible for the civil affairs, agricultural affairs, industry, etc. in Jingle and Lan County. Although it is still a bit messy and there are often big and small problems, they are generally in normal operation.
After Wang Jizong, Wencheng and others reported on their work, Qin Chuan, who was isolated, felt a little idle and ran outside Mengjiazhuang to see the workers rammed earth and built walls.
The original Mengjiazhuang covers an area of about 25 acres. Now the city wall is built two hundred steps away. After the expansion is completed, it will be more than three times the original area, covering more than 80 acres. A military fort will be built, and it will be the political center of the Qinchuan power in the future.
As his old nest, Qin Chuan had already thought of the name in advance, and it was called Heishan Fort.
He is going to be an old monster in Black Mountain.
The east of this future military fort is a hillside. Just dig the hillside to a steeper level and the enemy will not be able to climb up.
But the city wall needs to be built on the west and south sides, and a new city wall that is more than one mile long is about 600 meters.
This is a big project. There are about a thousand workers working. Just leveling the land, laying the foundation with stones, and digging the moat, and the digging of the soil is used to raft the city wall.
Since the west is a slope of mountains, the terrain is uneven and there is an inclined ditch, the requirements for the city wall here are not very high, and a rammed earth wall is built.
Today, the western section has built a soil wall of more than one person high, about two hundred steps long. Some of them have been built with red bricks on the exterior walls. Instead of using glutinous rice juice, modern mortar made of cement, lime mortar and fine sand made by Qinchuan is stronger than that of glutinous rice juice.
After building the exterior wall, plywood will be installed on it and rammed the earth. Once the layer is rammed, one layer of the exterior wall will be built. Finally, a city wall of two or five feet high, which is about eight meters.
The walls of the city wall are not vertical, but are tilted inward about eighty degrees, mainly to prevent the wall from collapseing outward when it is bombarded. The top of the city wall is one meter wide, and one enemy platform is built every forty steps, protruding outward.
To the south is the front of the entire military fort, with a relatively flat and open terrain, so the wall on this side will be unprecedented, creating a historic reinforced concrete structure.
Qinchuan has a crazy heart for infrastructure.
The southern wall of Heishan Fort was used to practice. It was planned to build three feet high, two feet thick with a red barbarian cannon of several thousand kilograms, and even if it came, it would not be able to penetrate such a thick reinforced concrete. The inner wall was one and a half feet thick, and it was hollow, with a total of three floors high, and it could be used as a military camp inside.
Including the protruding enemy platform, gun holes and gun holes will be left on each floor of the exterior wall. Soldiers can shoot outwards, from bottom to top to form a three-dimensional defensive firepower.
This is just a test wall. If feasibility, practicality, cost and so on are fine, Qin Chuan wants to build several castles that will never fall in the area of Guihua City.
That's right, he wanted to send troops to Guihua City.
If historical development is made, Lin Danhan will burp in the next year, and his son will surrender to the Later Jin. From then on, the rich and prosperous Hetao area will completely fall into the hands of the Later Jin.
Qin Chuan wanted to seize food from the tiger's mouth, but within two or three years he would definitely not have the strength to fight a large-scale field with the Later Jin Dynasty, but he could be an infrastructure maniac and build military forts and push them all the way.
He plans to complete the plan within two years.
Before again, he had to get out the steel bars first.
After squatting outside Mengjiazhuang for a long time, Qin Chuan hit Heishan and went to the iron farm and cement factory for a walk.
During the period when he went out to suppress the bandits, the iron ore, coal yards, iron smelting plants in Montenegro had all been laid on the rails, and even several mines were connected to the tracks.
The original ore had to be carried out from the miner in a basket, and then transported it to the material pile yard or large furnace by mule cart or chicken bus. After the tracks were established, eight mules and eight rail cars completed the workload of dozens of mules and hundreds of people, and the efficiency was greatly improved.
Now, the track leading to the cement plant and lime plant is being laid. After completion, a track from Heishan to Loufan Town will be laid, with a total length of twenty miles.
This is a big project, and it is also used by Qinchuan to practice. If this railway track can be laid out, he would dare to connect Loufan, Jingle and Lan County by railway.
Yan Sanqi had already handed over the casting of railway tracks and laying railways to several skilled craftsmen, and the pot factory had a dedicated person to take charge, while he was busy with another thing: making steel bars.
Not long ago, he had already made iron molds and other corresponding equipment for manufacturing steel bars according to the drawings given by Qin Chuan.
When he heard that Qin Chuan came back, he put down the iron model and waited for Qin Chuan to guide him personally.
When Qin Chuan arrived at the iron farm, Yan Sanqi led a group of craftsmen out to the gate to greet him.
Several steps away, Qin Chuan smiled and asked them to go in first, while he followed behind him, keeping a few steps away from them.
When he arrived at a newly built shed, Qin Chuan met the mold he designed himself.
This thing is actually a large syringe.
Pour the colloidal molten iron into it and start squeezing it. The molten iron will drill out from the hole half the finger-sized at the front end, enter the rotating conveyor belt, and be carried forward. The molten iron behind is constantly squeezed out, eventually forming long steel bars.
Qin Chuan didn’t know if he had achieved the quality of steel, but it would be called steel bars anyway.
While observing, a furnace Ding shouted to the side by the refining furnace not far away: "Mr. Qin, Mr. Yan, the iron has been refined."
"Okay, then hurry up."
Qin Chuan immediately stepped back and waved to Yan Sanqi to start.
"Pour molten iron and bring it over."
Yan Sanqi waved to the refining furnace.
The Lu Ding there began to get busy. Not long after, a pot of iron was pushed over by the chicken bus.
The steel bar factory next to the iron yard has not been completed yet, so today's trial steel bars are temporarily carried out in the iron yard. There is not much open space next to the Dajian Furnace, so it is far away and can only transport the iron and water.
When transported here, the originally liquid molten iron just cooled to a gel, just right for extruding the steel bars.
Under Yan Sanqi's command, two furnace diggers poured the iron into the iron mold, and then two craftsmen slowly pushed the piston shaft of the iron mold and squeezed the iron into the hole at the front end.
The red iron bar was quickly squeezed out, entered the transmission belt, and slowly moved forward.
When the iron bar reaches one meter long, Yan Sanqi personally used a guillotine to cut off the iron bar. A steel bar that is half a finger thick and a length of one meter long came out.
There are still iron bars behind them being squeezed out continuously. When all the molten iron is consumed, five steel bars are just out.
Qin Chuan was watching from the side. There were no mistakes in the whole process, but he was a little tired of manual operations.
After the steel bars were almost cooled, Qin Chuan put on thick gloves and lifted one of them and weighed them.
This is squeezed out of iron with a carbon content slightly higher than that of wrought iron, and it is slightly thicker than later coil steel bars. From the cross-section, the quality is of course not as good as that of coil steel bars, but the toughness is very good, and the quality should not be much worse.
After lifting up the other few steel bars to check, Qin Chuan nodded with satisfaction: "Yes, just follow this method. When will the steel bar factory start construction?"
Yan Sanqi replied: "Sir, the stove over there has been built, and the shed and the like have been built, but there is only one set of molds for the time being."
"How long will it take to make twenty sets of molds?"
"If you put down the rails first, it will take seven days."
"Okay, then I'll stop rail production first, make all my efforts to make molds, and send a batch of steel bars to Loufan in half a month, and start construction for the south wall of Heishan Fort."
"yes."
"By the way, there is iron wire. Make a batch of small size molds to make iron wire. The more you need, the better. I will transfer a group of people to help you tomorrow. I just brought 10,000 people back. There are many laborers. If you want them, you can ask Wencheng directly if you want them."
"good."
"What's the situation in the pot factory?"
"Everything goes well. Now the pot factory has thirty sets of molds. Eliminating the scraps, it can produce 400 iron pots every day."
"Well, it's good. After the production of steel bars and wires comes on track, you can just have a height of 10 or 20 sets of molds. There is no need to produce too many, just seven or eight hundred a day."
"yes."
"You guys are busy, I'll go to the cement factory and the lime factory."
"Okay, sir."
Qin Chuan waved his hand and told them not to send him off, so he took his red-clothed servant to the iron yard and headed to the cement factory five miles away.
Today, Jingle and Lan County have opened several gypsum factories, with stable and sufficient sources of gypsum, and the cement factory has reached a daily output of 20,000 jin.
Twenty thousand kilograms are only ten tons, which is a pitiful small output for cement plants that produce thousands of tons a day in later generations.
But it is already very good for Qin Chuan. You must know that now it all depends on manpower and accumulation to crush the stone and then grind it into powder. These two processes consume most of the manpower and time.
The lime factory was next to the cement factory and dug three stoves. The limestone piled into an arch in the stove. It burned coal at the bottom. It could burn 60,000 kilograms of limestone at a time. It would take four days and three nights to burn the stones thoroughly, and then the lime would be born.
Now Montenegro has formed a small industrial zone, including coal mines, coking plants, iron ore, iron smelting plants, iron pot factories, steel bar factories, cement factories, and lime factories. The total number of workers is more than 8,000.
Moreover, it will continue to expand in the future and will continue to increase workers.
After a walk around, Qin Chuan beat the horse back to Loufan, then called his father-in-law out and told him that when the Yang family in Dezhou came to buy iron materials and iron pots next time, they would not charge silver, and asked them to use grain to offset 80% of the payment for the goods, and the remaining 20% were offset by bronze and brass and other goods.
