The next day, Chen Xu got up early in the morning and personally sent water to the Women's College to class. Looking at the hundreds of carriages that were blocking the door to send students to school, Chen Xu decided to go back and continue to improve the planning of the bus company. With foreign investment and Feng Quji's solution policy, it can be said that the bus company has completed most of the completion. The following is to improve the details and then let Yang Kun implement them step by step.

"Mr. Marquis, President Zhang asked you to go to the Academy of Sciences to discuss the bridge repair!"

When Chen Xu's carriage just arrived near the Qinghe Marquis' Mansion, he was stopped by his secretary Sun Shujiong.

"Have you found the location of the bridge?" Chen Xu was surprised and overjoyed.

"I heard that I have found three places and I need the Marquis to get the idea!" Sun Shujiong nodded.

"Let's go to the Academy of Sciences!" Chen Xu slapped the handrail of the carriage a few times. The coachman turned the front of the carriage, 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 able to pass through trucks. Therefore, this straight cement road has suddenly become the most convenient road for cargoers to drive goods to the south terminal of the city. A horse is dragging a truck weighing more than ten stones and running fast on it. Even a wheelbarrow can drive three stone goods to easily walk. Therefore, this road is full of traffic all day long and has become the busiest road for freight. Even idle people who do nothing like to walk around and feel the magic of this road.

Zhang Cang led a group of craftsmen and craftsmen of the Academy of Sciences to search and calculate for nearly ten days, and then surveyed seven or eight suitable bridge locations, finally determined three places, and drew drawings, roughly calculating the required amount of cement, sand, gravel and steel bars.

Chen Xu spent almost half an hour in the Academy of Sciences. After listening to Zhang Cang's report in the conference room, he took a group of people to check these three locations in person. After repeated comparisons, he determined the location of the bridge repair. It was five miles below the east gate of the city. It was only seven or eight miles away from the water truck, which was close to the factory. Moreover, both sides of the river bank were relatively open, and the water flow on the river surface was very smooth. The most important thing was that there was a sandbank in the center of the river, which was convenient for unloading cement, gravel and wooden boards, and it was easier to dig the river channel to build bridge piers.

Standing by the shimmering river and looking at the river beach that has appeared in the dry river bank for several days, Chen Xu nodded and said, "Although this is the widest position, it is the easiest place to construct. At present, the cement and steel bars and sand are still in progress, but time does not wait for anyone. So, we quickly arrange people to repair the guide bridges on both sides of the river first. Because the river bank is easier to construct, we should extend the guide bridges at both ends to the middle of the river as much as possible, and try to shorten the distance between the two bridge piers as much as possible to ensure the stability of the bridge. At the same time, we can arrange people to dig two bridge piers foundation pits based on the sandbank to start pouring the bridge piers. Only after the bridge piers are completely solidified can the bridge body be poured..."

"What the Marquis said is that according to our plan, the guide bridges at both ends extend ten feet into the middle of the river, so that the middle part of the river will be only forty feet wide, and two bridge piers are set up, and the bridge arch is only twenty feet. In addition, the water flow in this place is smooth, so it is more convenient to build scaffolding at that time!" Zhang Cang also nodded repeatedly and said.

"Then let Zhao Qing be responsible for this matter. You can directly put Zhao Qing in charge of this matter. After leveling it, it will be used to accumulate sand, gravel, bamboo and wood, build a shed and pile up cement, and build a construction headquarters as soon as possible. The construction will be started as soon as possible while the weather is sunny and strive to complete it within two months. Otherwise, if it is dragged until the beginning of winter, the concrete may not solidify well, resulting in unstable quality of the bridge."

"Don't worry, the bridge is only sixty feet 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 very excited.

Chen Xu has studied the bridge repairs many times with Zhang Cang and a group of craftsmen and craftsmen from the Academy of Sciences, and everyone is very serious.

The locations of these three bridges were also repeated comparisons by the Academy of Sciences and after a lot of measurements and calculations, each completing the preliminary project budget. Although the location chosen by Chen Xu is the farthest from Xianyang City, it is the easiest place to be built. Before there is any experience in building concrete bridges, the simpler, the more convenient, the better. Saving money is the first condition to give up.

The precautions and construction methods for bridge repair have been discussed at several meetings at the Academy of Sciences. The construction of bridge piers, bridge arches, bridge decks, and how to build the guide bridges at both ends have been summarized. Now we are just waiting for construction. In addition, the continued drought after the autumn this year, for farmers, grain production will be reduced, but it is indeed the best weather for construction on the river surface.

Chen Xu couldn't get into the rest, because repairing bridges was not a mature skill on the skill tree for him. The only thing he was proficient in and had the skills distribution point was to eat. In the world of Qin and the entire earth, there were countless delicious foods. Therefore, repairing bridges could only be left to Zhang Cang and the craftsmen to explore slowly.

Seven or eight miles down the river is the water truck under construction.

Chen Xu sat on the bumpy carriage and soon saw the big water truck. The whole thing was completed, like a giant wheel mounted on the Wei River, very eye-catching.

The reason I chose this location was because the riverbeds were large, and there was a slender sandbank in the middle of the river, which could be used to build a separate dam. In this way, the water flow that drives the water truck is separated from the main river channel, so that the water rises in summer will not destroy the dam.

The dam officially started construction in March and only took more than a month to start summer. Because there is a lot of rain in summer and floods often break out in the Wei River, the repair and stopping are basically in a semi-stop state. Therefore, it was not until the end of June that the continuous drought of the Wei River subsided, and the dam began to be built again.

Under Chen Xu's urging to complete the work as soon as possible, Zhao Qing informed Qin Shihuang that the Ministry of Works ordered thousands of prisoners and labor slaves to participate in the construction of the dam. Recently, the dam has only begun to change in almost a day.

A tilted stone wall nearly ten meters high and about two hundred meters long has been built on the sand dunes in the middle of the river. This wall is the main body of the dam, and the whole is in the shape of a plowshare pointed in front and blunt in the back, which is easy to resist the impact of the water flow above. The river bank is also piled up next to each other with huge bluestone strips, and the length is 200 meters. The two stone walls clamped together to form a new narrow river channel. At this time, the above of the river channel has been sealed by a temporary dam, diverting the river water into the main river channel. A few meters away from the water truck, a transverse dam about ten meters wide is under intense construction.

The long crane arm was hanging with large stone strips swaying in the air. Countless ragged prisoners and labor slaves pulled thick hemp ropes under the scorching sun. Under the command of craftsmen waving the flag, huge bluestone strips weighing hundreds of pounds were lifted to the required position.

In addition to the craftsmen and labor slaves who built the dam, hundreds of people gathered on the river bank to watch the fun.

These are all the people of Xianyang who do nothing. They ride horses and walk to see this strange project when they are bored on weekdays. Among them are not only kings, princes, princes, playboys, disciples, but also many merchants and famous scholars, and even journalists from newspaper offices.

This situation has been around since the dam started construction. As the dam and water trucks took shape day by day, more and more people came to watch. Sometimes there were thousands of people gathered together and were very lively. Many people with agility set up barbecue stalls and pancake stalls on the banks of the river to sell some food. Because the newspapers announced the method of making ice powder, there were even several women selling ice powder. They did not have ice, but only put a little fruit vinegar, two yuan per bowl, and the business was still very popular. Therefore, in recent times, this place has become a very lively place outside Xianyang City, and there are people everywhere every day.

Seeing a luxurious four-bridle carriage coming under the protection of the burly guards, the people who were watching the fun naturally recognized that it was Qinghehou's carriage. So in a loud shout, the onlookers consciously dispersed a way and let Chen Xu's convoy pass.

"Mr. Marquis, you are a rare guest. I thought you had forgotten the flood truck. I didn't even take a look at it for more than ten days after starting construction!" Fang Kuan, who had climbed up from under the river bank, was covered in sweat. He took off the rattan hat on his head and fanned the air.

Chen Xu got out of the car and looked at the busy scene in the river and frowned and said, "Last time, you said the dam was almost repaired, why is the dam body not yet completed?"

Fang Kuan's face suddenly turned like bitter gourd, and he lowered his head with his eyebrows and eyes squinting, "Mr. Marquis, it was already repaired, but a few days ago, when the water was released and tested, it was found that the amount of water was too large and fierce, and the dam was not strong enough. The next day, it washed away a section of the dam. Fortunately, the water truck was mounted on the stone walls on both sides, so it was not washed away by the water, so it had to be rebuilt!"

"Is anyone injured or washed away?" Chen Xu asked with a dark face.

"Don't worry, Marquis, no one was injured. The construction site was closed during the test and all personnel had evacuated to the shore!" Fang Kuan said quickly with his sleeves, wiping his face full of sweat.

"That's good. Remember the construction regulations on the construction site. If you die, I will deduct a monthly bonus for you!" Chen Xu threatened Fang Kuan fiercely, then looked at the busy workers and said, "It's autumn now, and it won't rise again. You have to speed up. Also, who designed the dam last time? Why is it not strong enough?"

"This...this..." Fang Kuan hesitated for a long time, blushing and whispered: "Mr. Marquis, I designed the dam last time, but Marquis don't worry, this time I found a guy very powerful. He redesigned the dam and would definitely block the river!"

"Go bring me a look!"
Chapter completed!
