There was another exclamation in the conference room, and countless people scrambled to stand up and prepare to ask questions, but Chen Xu raised his hand to stop everyone.

"Ladies and gentlemen, those who walk a hundred miles are half ninety, do not accumulate steps to thousands of miles, do things like eating, need to chew and swallow slowly, so, I hope you can think about this matter I just said, with the experience of building a water tower to see how to build a four-storey or five-story or even seven-eight-storey high-rise building, in order to make you more intuitive, I will now draw a construction sketch for you, and we will carefully figure it out after we go down, if anyone has the confidence to build, I will allow him to build a high-rise building where employees live in the factory outside the city."

"Master Hou, you have to talk about it!" Seven or eight craftsmen and craftsmen who were proficient in construction stood up excitedly.

"Ben Hou naturally speaks, but everyone must be mentally prepared, although the construction of high-rise buildings with reinforced concrete is very fast, but it needs to be strictly designed to bear the load and disperse the pressure on the ground, otherwise I am afraid it will collapse, everyone first look at my sketch, and then go to the design slowly......"

Chen Xu picked up chalk and a ruler and quickly drew a sketch of the structure of a later university dormitory on the blackboard.

"This building is seven feet high, with five floors up and down, each floor is about one zhang and four feet high, and there is a staircase in the middle to the roof to connect the five floors together, and the two sides of the staircase lead to the corridors on each floor, and the corridor leads to the staff dormitories, each of which is four feet long and three feet wide......"

The dormitory is the simplest high-rise building, Chen Xu pointed to the building with a bamboo stick and gave a general introduction: "The structure seems simple, but to build it perfectly, you need to carefully figure out the structure, considering the pressure of such a high building on the foundation and the weight of the wall itself, so these load-bearing walls and corridor frames must be poured with reinforced concrete, and other places are filled with masonry, stairs and floor slabs can be made of wood, of course, you can also use reinforced cement to pour into suitable concrete slabs instead of ......"

"Master Hou, such a tall building, seeing that you have painted more than ten houses on each floor, how many people will live in this building?" A craftsman couldn't help but stand up and ask.

"The factories outside the city now have nearly two hundred supervisors, craftsmen, craftsmen, helpers and managers of various departments, not including the slaves and prisoners, if all of them add up to thousands of people, I plan to have one room for supervisors, craftsmen and craftsmen, four apprentices for helpers, and eight others for one room, if they are all to be settled, they need almost five to six such five-story buildings, if any of you can complete this task, they will definitely leave a name for all generations in the future, and be known as a master of high-rise buildings!"

Chen Xu's last sentence directly ignited the mood of the entire conference room, countless people jumped up and shouted to be the builder of these high-rise buildings, looking at the hot scene of nearly two hundred people shouting like a vegetable market, Chen Xu knocked the table a few times with a blackboard brush, and after everyone quieted down, he said: "This matter is not in a hurry, and it is not the task I came to arrange for you today!" ”

Zhang Cang was puzzled and said: "Master Hou made me a surprise, and I am ready to volunteer to take over the high-rise project you mentioned?" ”

"Although repairing the building seems complicated, there is no need for a mathematical genius like Dean Zhang, I have a very important task for you today!"

"Please command!" Zhang Cangping's face became slightly serious.

"Build the bridge!" Chen Xu nodded and said.

"Repair the bridge? Where to build bridges? Not only Zhang Cang, but many craftsmen and craftsmen looked at Chen Xu.

Chen Xu picked up the blackboard brush and erased all the sketches of the building that had just been drawn on the blackboard, then turned around and said: "I want to arrange an unprecedented but very important task for me in Xianyang today, that is, to build a bridge over the Wei River, across the north and south ...... of the Wei River."

"Master Hou, isn't there already a bridge on the Wei River?" Hu Kuan raised his hand and stood up and said.

"The current Weihe Bridge is a wooden bridge, no more than two zhang wide, and all are wooden structures, walking on it shakes badly, the wind and rain rain down the rope and wood are very tolerant of decay, in the summer water, but also may be washed away by the wooden bridge, I heard that a few years ago the wooden bridge was washed away by floods, resulting in the Weihe River on both sides of the traffic cut off, can only be through ships, the edict and the chapter is very troublesome, the people's lives are also greatly affected, so I am ready to set up a Weihe Bridge project headquarters, by President Zhang is in charge, It also organized some craftsmen who are proficient in bridge design and manufacturing to build a three-zhang wide concrete bridge with reinforced concrete, so that the north and south of the Wei River will be changed from now on, so that the north and south banks will no longer be affected by the collapse of the bridge! ”

"Okay, good, Hou Ye really has a long-term vision, once this Weihe Bridge is built, it will inevitably make Xianyang more prosperous, and the two sides of the strait will inevitably be one, and there is no distinction between north and south!" Zhang Cang stood up excitedly and applauded.

And all the craftsmen and craftsmen in the conference room had their eyes lit up.

Think about a three-zhang wide reinforced concrete bridge across the Wei River, the people from the south to the north and countless carriages full of goods pass through it in an endless stream, instead of being monitored by soldiers as now, all the trucks can only pass one by one, and they are not allowed to go when encountering heavy goods, last time Nanyang transported forty cars of tiles and porcelain to Chen Xu, one by one It took more than an hour, and this is still the carriage with the banner of the Qinghe Houfu, if it is an ordinary businessman, such a heavy cargo will not be allowed to pass, Directly ask to unload and hire a helper to carry it over one by one, which will take at least a whole day.

Although Chen Xu does not walk the Weihe Bridge often, he feels frightened after walking a few times, sitting on the carriage and creaking through it, feeling that the whole bridge is shaking, and the wooden planks are also creaking and making various overwhelming sounds, as if they are going to break at any time.

Therefore, both sides of the Weihe Bridge are now the intestinal obstruction of the entire Xianyang traffic, the two ends of the bridge are lined up in a long line of carriages all day and night, and the official car driver must be given priority to pass, some merchants have to wait for half a day to cross the bridge, and those who can't wait can only spend more money to transport it to the wharf and transport it to the other side of the river by boat and then arrange loading, which is a big expense.

Therefore, since the successful development of cement, Chen Xu began to make up his mind to build the Weihe Bridge first, and the construction of the Weihe Bridge will inevitably have supporting cement roads, approach bridges and various countless problems that need to be solved together for the cross-river bridge.

Led by the Academy of Sciences, the Ministry of Engineering, the Shaofu and the Inner History Office will be organized to complete this unprecedented project, which will inevitably accumulate a lot of experience in building roads and bridges, and cultivate a large number of craftsmen and craftsmen who can take charge of themselves, and then they can start to build cement factories on a large scale in the country, open roads and build bridges in the mountains and rivers, and rebuild the roads that now extend in all directions into cement pavement.

With a flat cement pavement and a solution to the traffic problem, the country's traffic and cargo transportation will increase several times, and the connection between various places will be closer, so as to promote Daqin to start to run forward.

If you want to get rich, build roads first!

After Qin Shi Huang came to power, he was recruiting servants to build and expand the Chidao Straight Road every year, with the purpose of strengthening the ties of the whole country, and if he saw the cement road, he would definitely spare no effort to support this matter.

Chen Xu originally said that he wanted to study the immortal art of turning mud into stone, and now that he succeeded, he used this Weihe Bridge to dispel all the doubts of the emperor and give him infinite confidence.

But the so-called everything is difficult at the beginning, and Chen Xu will not be able to repair the bridge at all.

It doesn't matter, although Daqin is relatively primitive, but in fact, there are many craftsmen and hundreds of scholars who build roads and bridges, he feels that he only needs to put forward the method of construction and the general style of the bridge, just like studying cement, he proposed the principle, so many people in the Academy of Sciences, under the collective wisdom and efforts, they have all succeeded in researching, which boosted his great confidence.

Although the Weihe Bridge is a super huge project, it brings together the best craftsmen and the best mathematicians in the entire Great Qin, plus the immortal disciples of the prophet himself, and pours the strength of the entire Great Qin If he can't handle this concrete bridge, then the industry behind him will not develop, because everything else is more troublesome than this except for road construction.

Chen Xu quickly drew on the blackboard again the style of a bridge across the river, with two piers in the middle, the bridge deck is straight, and the bottom is two arches.

After finishing the painting, Chen Xu pointed to the figure of the bridge with a bamboo stick and said: "Everyone, please see, this is the style of the bridge across the river that I roughly designed, these two are the piers, this is the arch of the bridge, the top is the bridge deck, there are four-foot-high railings on both sides, and the approach bridge on both sides of the bridge is ......."

The style of the bridge was very strange, the conference room was extremely silent, and everyone looked directly at the blackboard, for fear of missing a word from Chen Xu.

After introducing the structure of the bridge, Chen Xu said with a serious and serious face: "A few days ago, I went to the Wei River to have a rough look, the narrowest part of the river near the south gate of the east gate is about 30 zhang, and the widest part is about 100 zhang, and to repair this cross-river bridge, it is necessary to set up piers in the middle to share the weight of the bridge, but the bridge piers are built in the middle of the river must first build a cofferdam in the middle of the river to block the flow of water before construction, and at the same time, this bridge pier must also be able to resist the impact of summer floods, which needs to be surveyed and calculated first, and now it is about to enter autumn." Of course, the shorter the bridge repair, the less materials will be consumed, the less it costs, and the longer the bridge repair, the greater the cost, so I need you to go to the Wei River to carefully survey, find the most suitable location, and build the most stable bridge across the river under the condition of saving materials as much as possible, but the first is strong and safe, even if it is a little farther away...... ”
