Zhao Xingde shook his head and said with a smile: "You don't need to customize it from the Song Kingdom, you can build the components used in the city nearby." ”

"What is the solution Mr. Zhao said?" Han Ningshuang's tone was full of hope, and the other Han army generals were suspicious, everyone put down their wine glasses, looked at Zhao Xingde, and waited to listen to his next words. The candles around the Chinese military tent shone brightly on the faces of different complexions, showing different emotions. "Could it be that Mr. Zhao is really the reincarnation of Kong Ming, and he can still create a wooden ox and a flowing horse?" Xu Detai said secretly in his heart.

"Now the Nanshan city wall is rammed slowly, and the place is small, even if more manpower is invested in it, it will not be able to be used." Zhao Xingde said in a deep voice, "But we can build Nanshan City by using the method of using a farm." ”

"Factoryization?" Han Ningshuang chewed on the word thoughtfully. The other Han generals also had a puzzled look on their faces.

"Exactly." Zhao Xingde was faintly excited, "We can build a prefabricated workshop near Nanshan City at the same time, first use wooden or iron plates to make specific molds, and then ram the rammed earth to build the city wall into various prefabricated parts, and then use these large prefabricated parts to build the city wall." "This industrial system of architecture originated from later generations, and the prefabricated parts were mostly made of reinforced concrete, steel, and synthetic materials. In the ancient times of rammed earth to build cities, ramming prefabricated parts in an industrialized way, and then rammed earth prefabricated parts to construct and splice the city wall, is a thing that has never been done before and after it.

"Isn't it just mud bricks?" Wang Xuansu frowned and thought, "I thought you had a good idea." He leaned back and said in a rather expert tone: "It's okay to build a farmhouse and thatched hut with mud bricks, but it's too unstrong to build a city wall, not only can it not withstand the artillery bombardment, but after a few heavy rains, the mud brick wall may be soaked and collapsed by the rain." ”

Xu Detai's face showed a look of disappointment. Han Ningshuang's eyes moved slightly, what Zhao Xingde said and what Wang Xuansu said didn't seem to be the same thing, but what was the difference, she couldn't say.

Wang Xuansu continued: "The city is built with rammed earth, the city wall is strong and not easy to collapse, the entire city wall is one, and the enemy army attacking the city cannot pry down the mud bricks piece by piece. Its practical stones and bricks are better covered outside the city walls, which can not only prevent rain soaking, but also make it difficult for enemy troops to enter. ”

"The rammed earth prefabricated parts are a bit similar to the mud bricks, but the difference is still not small," Zhao Xingde said, gesturing, "First of all, the material of the rammed earth is different. The ramming method used by your army to build the Nanshan city wall was originally based on the clayey red clay produced in Guannan, Suzhou, and then mixed with lime, sand, brown sugar and rice milk, and then rammed it tightly and solidly with a stone rammer and pestle, so it was difficult for the rain to soak it softly, and it was much harder than the mud bricks of ordinary farmers. This is also the case with this rammed earth prefabricated part, because the material is special, and after vigorous tamping, it is much harder than the mud bricks of ordinary farmers, and it is not easy to be soaked and softened by rainwater, or even ......," Zhao Xingde said thoughtfully, "Because these prefabricated components are made in the workshop, we can use stone pounding pestles pulled by oxen and horses to increase the tamping force, so that the standardization of the prefabricated parts even exceeds the original rammed city wall in uniformity, tightness and hardness." Compared with the mud bricks of ordinary farmhouses, there is a world of difference. ”

Han Ningshuang listened to Zhao Xingde's explanation, and was quite moved, Xu Detai's face was suspicious, Du Chuijiao looked admiring, but Liu Zhijian was thoughtful.

Wang Xuansu frowned and said: "This rammed 'prefabricated part', can it still be harder than the city bricks?" According to what Mr. said, it is better to simply burn the bricks to build the city wall. He has been immersed in the road of building the city for a long time, and the Nanshan City originally designed by Wang Xuansu was a combination of the advantages of the French style of the world's cities, but because of Zhao Xingde's intervention, it was completely overthrown. Although he also thought that Zhao Xingde's redesigned Nanshan City was easier to defend, there was always a knot in his heart, and now that he seized the opportunity, he couldn't help but gush on Zhao Xingde's "mud brick" to build the city inappropriately.

Zhao Xingde said with a smile: "This is the second difference, the size of the city bricks is limited by the firing, if it is too large, it is easy to crack." The prefabricated parts of the ramming can be much larger than the city bricks, as long as the tamping force is enough," he gestured with his hands, "There should be no problem with a few feet of length, width and height, which is much thicker than the city bricks, and because the prefabricated parts are too large, it is impossible for the enemy to pry them out in their entirety when attacking the city, or they can only hollow out the city foundation little by little like they do with the rammed earth city wall." ”

"Even if such a large 'prefabricated part' is manufactured, it will be difficult to handle, right?" Xu Detai hesitated.

"The rammed earth with a few feet of length and width can be moved by a horse-drawn cart or even a cart," Zhao Xingde said with a smile, "General Xu asked the idea, and it is estimated that the larger the rammed earth prefabricated parts, the faster and stronger the city wall will be, but unfortunately it is limited by the carrying power, and the length, width and height of the prefabricated parts are already a few feet limit." "In winter, you can make the prefabricated pieces heavier and bigger by adding ice and rolling wood." ”

"Mr. Zhao said that the prefabricated city construction method, these large soil blocks are built together, I am afraid that the artillery of the Liao State will collapse with a bombardment, and there will be gaps between the soil blocks, and it is inevitable that rain will leak."

Zhao Xingde replied in a deep voice: "ramming prefabricated parts is more convenient than burning bricks and stones, and the mold can also have all kinds of changes, if you can refer to the method of mortise and tenon of carpentry, so that the prefabricated parts are bitten together with each other up and down, left and right, as for the gaps between the prefabricated parts, you can use the mortar that binds the city bricks." There are so many walls in the world that are made of bricks, and there are no cracks or leaks. ”

"The method of carpentry mortise?" Wang Xuansu was surprised and said, "How can it be used to build a city with rammed earth, this method is too whimsical, and Wang is really unheard of." ”

Xu Detai next to him also hesitated and asked: "Mr. Zhao, do you have the previous French style to refer to your rammed earth prefabricated method of building a city?" ”

Zhao Xingde was a little embarrassed and said: "This method of creation is unprecedented. ”

Wang Xuansu said in a deep voice: "This method of prefabricated parts construction has not been seen in previous generations, and it is unheard of, and it is really difficult to plan everything. "He looked at Zhao Xingde at first, and then said to everyone," Wang thought, "Although Mr. Zhao is kind, Nanshan City is very important, and Mr. Zhao said that this method of building the city should be used carefully." ”

"Can you first ram out some of the 'prefabricated parts' that Mr. Zhao said, and try to build a section of the city wall to see the effect?" Han Ningshuang said in a deep voice, she listened to Zhao Xingde's explanation very reasonably, and realized that the construction method of factory-based production of prefabricated parts is most suitable for large-scale projects, if it is really feasible, not only to build Nanshan City, but even the entire fortress in Guannan, Suzhou, can be used, so Han Ningshuang can still want to try it.

"Yes, if you are worried that you are not sure, you can try to build a section of the city wall first." Zhao Xingde also said. Later generations of prefabricated parts did not have rammed earth materials. He is not completely sure about building a city with rammed earth prefabricated parts, so he also tends to try to build it first.

Wang Xuansu shook his head and said in a deep voice: "If the city wall built in this section is too short and too small, it will not be able to prove that Mr. Zhao's construction method is reliable, but if it is built high and large, in case it fails, the waste of artificial and material resources is not a small number." Although there are more than 100,000 soldiers and civilians in Kannan, there is a shortage of manpower of all kinds, and there are no extra people to do this trial construction. ”

This is a master and apprentice teaching, following the era of building the French style, from the city wall, the palace to the private garden, the construction of any building is based on certain rules, in most people's concepts, not in accordance with the construction of the French style to build the building must not be long, even very dangerous, the so-called "gentleman does not stand under the dangerous wall", even if it is an ordinary house, very few people are willing to try a new construction method, not to mention the vital Nanshan City. Zhao Xingde repeatedly considered a lot of technical details of rammed earth prefabricated city construction, but did not take into account people's acceptance.

At this time, Wang Xuansu was already out of public intentions, and he did not intend to target Zhao Xingde. More than anyone else, he wanted Nanshan City to be built on time, but he was even less receptive to the use of an unheard-of method to build the all-important city of Suzhou. He finally sighed and said in a deep voice: "Mr. Zhao, I'm sorry, it's about the lives of the soldiers." The new way of building the city that you came up with is not reliable, and I will not use it. ”

Wang Xuansu was the general who presided over the construction of Nanshan City, and his attitude was so clear that Han Ningshuang frowned slightly, although he intended to try, he couldn't help but pay attention to his opinion. She made a decision, glanced at Zhao Xingde with some apologies, and asked, "General Zhao, if you only do it in the construction method that has been commonly used in the past dynasties, can you have a way to speed up the progress of building the city?" ”

Zhao Xingde was extremely disappointed in his heart. He had spent a lot of thought in the past few days to apply the construction method of the industrial system to rammed earth to build a city, and now it was like a punch in the air. This idea is the proof of the only missing experiments, which implements specific technical details. However, he still smiled and said: "If you only use the French style commonly used in the past dynasties, you can imagine that the height of the city wall is reduced, and the thickness of the rammed earth is reduced, and the structure is strengthened with giant trees in the city wall, and that's it." ”

Han Ningshuang's eyes lit up and muttered, "Do you use more giant trees?" Wang Xuansu also nodded, and the Han army also used mixed civil and engineering structures to build cottages. In the commonly used rammed earth construction method, it is also mentioned that wood can be buried in the wall as a wall bone, and Zhao Xingde's proposal to use giant wood to build a strong frame to strengthen the city wall that was forced to be thinned is a way. The thickness of the wall is closely related to the height, although the city wall is forced to be lowered, but as long as it survives this winter, the city wall will be thickened and heightened again next year, these are the methods of building the city.

"Such a simple method, I didn't think of it." Wang Xuansu secretly blamed himself. Because the Han army's formal French method of building a camp and building a city with a mixture of civil and engineering were completely two ways, he never considered strengthening the city wall with wooden structures. At this moment, Wang Xuansu had a feeling of sudden realization. He looked at Zhao Xingde's gaze with a little more admiration. This person is not confined to the law, although the construction method proposed at the beginning is whimsical, but he is not stubborn, and then he proposes a remedy, as if it is unthinkable.

"General Zhao's guidance, Wang Mouming felt in his heart," he said sincerely, "This city was originally designed by Mr., and it is feasible to replace rammed earth with giant trees. ”

"Well said, well said." Zhao Xingde returned the salute with some loss. He deeply felt how difficult it was for Chun Yuzhen to break his family and experiment in the production of a new type of cannon casting technique. Zhao Xingde forcibly restrained himself and let go of his loss. Two concerned glances were cast on the other side, and he also responded with a gentle smile, raised his glass and said: "Lord Han League, Zhao wishes Nanshan City a great success as soon as possible." ”
