The next day, Chen Xu got up early in the morning to personally deliver water to the women's college to class, looking at the mess blocked at the door of hundreds of carriages to send students to school, Chen Xu decided to go back to continue to improve the bus company's plan, with foreign investment, with Feng to solve the disease policy, it can be said that the bus company has completed most of the time, the following is to improve the details, and then let Yang Kun go step by step to implement the line.

"Master Hou, Master Hou, Dean Zhang, please go to the Academy of Sciences to discuss the repair of the bridge!"

Chen Xu's carriage had just arrived near the Qinghe Marquis Mansion when it was stopped by his secretary Sun Shujiong.

"Have you found a location to build the bridge?" Chen Xu was surprised and overjoyed.

"I heard that I have found three places, and I need Master Hou to get an idea!" Sun Shujiong nodded.

"Let's go, go to the Academy of Sciences!" Chen Xu slapped the handrail of the carriage a few times, the coachman turned the head of the car, and a group of people escorted Chen Xu to the Academy of Sciences.

After a period of time, the cement road outside the south gate of the city has been completely solidified and strong enough to pass the trucks, so this straight cement road has suddenly become the most convenient road for the merchants to drive the goods to the south wharf of the city, a horse pulling a truck with more than ten stones on it runs fast, even if it is a wheelbarrow a person can push the three stone goods to walk easily, so this road is busy all day long and has become the busiest road for freight transportation, even idlers who have nothing to do also like to walk around on it, feel the magic of this road.

After nearly ten days of searching and calculating, Zhang Cang led a group of craftsmen and craftsmen of the Academy of Sciences to survey seven or eight locations suitable for building bridges, and finally determined three places, and drew drawings to roughly calculate the amount of cement, sand and steel bars needed.

Chen Xu stayed in the Academy of Sciences for almost half an hour, after listening to Zhang Cang's report in the conference room, he took a group of people to check the three positions in person, and after repeated comparisons, the location of the bridge was determined, just five miles below the east gate of the city, here is only seven or eight miles away from the big waterwheel, and the factory is relatively close, and both sides of the river bank are relatively open, the river surface flow is also very gentle, the most important thing is that there is a sandbar in the center of the river, which is convenient for stacking and unloading cement sand and wooden boards, and it is also easier to excavate the river to build bridge piers.

Standing on the sparkling river, looking at the river beach where the drought water fell for days, Chen Xu nodded and said: "Although this is the widest position, it is the easiest place to construct, at present, the cement and reinforced sand and gravel are still in preparation, but time waits for no one, quickly arrange people to repair the approach bridge on both sides of the river, because the river bank is easier to construct, so extend the approach bridge at both ends to the middle of the river as much as possible, and shorten the distance between the two piers as much as possible, so as to ensure the stability of the bridge. At the same time, people were arranged to excavate two bridge pier foundation pits relying on the sandbar and began to pour the bridge piers. Only after the piers are completely solidified can the bridge be poured......"

"What Hou Ye said is that according to our planning, the approach bridge at both ends extends ten zhang to the middle of the river, so that the middle part of the river is only forty zhang wide, two piers are set up, and the arch of the bridge is only twenty zhang, plus the water flow in this place is gentle, and it is more convenient to build scaffolding at that time!" Zhang Cang also nodded again and again.

"Then it was decided, you directly let Zhao Qing be responsible for this matter, expropriate the farmland on both sides of the riverbank, and use it to pile up sand, stone, bamboo and wood after leveling, build a shed and stack cement, and the engineering headquarters will also be built as soon as possible, take advantage of the good weather to start construction as soon as possible, and strive to complete it within two months, otherwise I am afraid that the quality of the bridge will be unstable due to poor concrete solidification after it is delayed until winter."

"Hou Ye rest assured, the bridge is only sixty zhang long, as long as the cement and steel bars can keep up, there should be no problem in repairing it in two months!" Zhang Cang was excited.

The matter of repairing the bridge Chen Xu has been repeatedly studied many times with Zhang Cang and a group of craftsmen and craftsmen of the Academy of Sciences, and all of them are very serious.

The location of these three bridges is also after repeated comparisons of the Academy of Sciences after a large number of measurements and calculations, each has completed the early project budget, although the location chosen by Chen Xu is the farthest away from Xianyang City, but it is the easiest place to build, without any experience in building concrete bridges, the simpler and more convenient the better, saving money is the first to give up the condition.

The precautions and construction methods of repairing the bridge have already been talked about in several meetings of the Academy of Sciences, the construction of the bridge piers, the construction of the arch, the construction of the bridge deck, and how to build the approach bridge at both ends have already summarized the solutions, and now we are just waiting for the start of construction, coupled with the continuous drought after the autumn of this year, the grain production will be reduced for farmers, but it is indeed the best weather for the construction on the river.

Chen Xu couldn't intervene in the rest of the matter, because repairing the bridge was not a mature skill on the skill tree for him, the only thing he was more proficient in and had a skill distribution point was eating, the Great Qin world, the whole earth, there were countless delicious things, so the matter of repairing the bridge could only be handed over to Zhang Cang and the craftsmen to slowly explore.

Seven or eight miles down the river, there is a large waterwheel under construction.

Chen Xu sat on the bumpy carriage, and soon saw the big waterwheel, which had been completed as a whole, like a giant wheel erected on the Wei River, which was very eye-catching.

The location was chosen because of the large drop in the riverbed and the fact that there is a slender sandbar in the middle of the river, which can be used to build a dividing dam, so that the flow of water that drives the waterwheel is separated from the main river channel, so that the dam will not be washed away by the rising water in summer.

The dam was officially started in March, and it was only built for more than a month before entering the summer, because there was a lot of rain in the summer, and the Wei River often broke out in floods, so the repair and repair was basically in a semi-suspended state, so it was not until the end of June that the autumn was almost over, and the continuous drought of the Wei River subsided for most of the time, and the dam began to be built again.

At the urging of Chen Xu to complete the dam as soon as possible, Zhao Qing informed Qin Shi Huang that the Ministry of Industry had conscripted thousands of prisoners and slaves to participate in the construction of the dam.

On the sand dunes in the middle of the river, a sloping stone wall of nearly ten meters high and about two hundred meters long has been built, this wall is the main body of the dam, the whole is in the shape of a ploughshare with a sharp front and a blunt back, so as to resist the impact of the water flow above, and one side of the river bank is also all piled up with huge bluestone strips next to each other, the length is also two hundred meters, the two stone walls are sandwiched to form a new narrow channel, and at this time, the river has been blocked by a temporary embankment, and the river water flows into the main channel, a few meters away from the waterwheel. A horizontal dam about 10 meters wide is under construction.

Countless ragged prisoners and slaves pulled thick hemp ropes under the scorching sun, and under the command of craftsmen waving the flag, huge bluestone bars weighing hundreds of pounds were hoisted to the required positions.

In addition to the artisan slaves who built the dam, hundreds of people gathered on the riverbank to watch the excitement.

These are the people of Xianyang who have nothing to do, and they are bored on weekdays and ride horses to see this strange project, among which there are not only princes and princes and princes and disciples, but also many businessmen and celebrities, and even newspaper reporters.

This situation has existed since the dam was started, and as the dam and the waterwheel took shape day by day, more and more people came to watch, sometimes there were thousands of people, gathered together to be very lively, and many nimble people also set up barbecue stalls and pancake fruit stalls on the bank of the river to sell some food, because the newspaper announced the production method of ice powder, and even several women who sold ice powder, not iced, but just put a little fruit vinegar, two dollars a bowl, the business is still very hot, so in recent times, This place has become a very lively place outside Xianyang City, and it is full of people every day.

Seeing a luxurious four-bridle carriage roaring under the protection of burly guards, the well-informed people who watched the lively crowd naturally recognized that this was the carriage of the Marquis of Qinghe, so in the midst of shouting, the onlookers consciously dispersed a road to let Chen Xu's convoy pass.

"Master Hou, you are a rare guest, I thought you forgot about this big waterwheel, and you didn't come to see it for more than ten days!" Hearing the news, Fang Kuan, who climbed up from under the river embankment, was covered with sweat, took off the rattan hat on his head, and said while fanning the wind.

Chen Xu got out of the car and looked at the busy scene in the river, frowned and said, "You said last time that the dam is almost finished, why is the dam not finished yet?" ”

Fang Kuan's face was distorted like a bitter gourd, and he lowered his head with a frown and said: "Master Hou, it was originally repaired, but when the water was tested a few days ago, it was found that the water volume was too large and too fierce, and the strength of the dam was not strong enough, and the dam collapsed the next day. ”

"Has anyone been injured or swept away?" Chen Xu asked with a dark face.

"Master Hou rest assured, no one was injured, the construction site was closed during the test, and all personnel have been evacuated to the shore!" Fang Kuan wiped the sweat on his face with his sleeve and hurriedly said.

"That's good, remember the construction site safety construction regulations, I will deduct your one-month bonus if you die!" Chen Xu viciously threatened Fang Kuan, then looked at the busy workers and said: "It's autumn now, the water won't rise anymore, you have to speed up, and besides, who designed the dam last time, why is it not strong enough?" ”

"This ...... This ......" Fang Kuan hesitated for a long time, blushing and whispering: "Master Hou, I designed the dam last time, but Lord Hou rest assured, this time I found a guy who is very powerful, he redesigned the dam, and it will definitely block the river!" ”

"Go and show me someone!"

"Master Hou, wait a minute!" Fang Kuan turned around and yelled at the bottom of the river embankment: "Shi Lu, Shi Lu, come up, Master Hou wants to see you!" ”
