Chapter 772

Underwater piling is a common bridge repair technology in later generations, but it is a difficult and even impossible task in this era.

For a moment, the whole Mohist school was worried, but there was nothing to do with its skills.

"Young master, why don't we also build an arch bridge? With the existing technology of Mohism, it's not too difficult to build an arch bridge. I've seen the bridge built by Li Yun, and it's not difficult to beat him." Lao Zhang said confidently.

Although Li Yun thinks he has mastered the most advanced bridge repair technology since Li Chun, he has fallen behind a lot in terms of Mohist technology. He is confident to surpass him.

Merton shook his head and said, "Your Majesty ordered the Mohists to build the bridge not just for this Qujiang bridge, but for a wider and longer river. The Mohists can indeed build the Qujiang bridge with an arch bridge. What if the Weihe River, the Huaihe River and the Yellow River? Do they all use an arch bridge.

Lao Zhang shook his head repeatedly. The arch bridge is only suitable for small rivers. If the river surface is too wide, there is no way to build an arch bridge. This is also the reason why large rivers can't build bridges in this era.

"But at present, not only the Taoist waidan sect has not developed cement that can solidify under the water, but also the silt at the bottom of the river is very deep. If the pile is forced, it is only afraid of the unstable foundation, it is impossible to set up the pier." Lao Zhang frowned and thought deeply. If the bridge body is unstable, even if it is forced to be built, it will be a waste bridge.

"Since we can't lay the foundation under the water, we can lay the pier foundation on the water." Merton suddenly had an idea.

"Lay a good foundation on the water?" Lao Zhang looked at Merton strangely as if listening to the book of heaven.

Merton smiled mysteriously: "in fact, the ancients have solved the problem of building bridges in the water, but we didn't find it!"

"The ancients have cracked it!" Lao Zhang was confused. The ancients already had a way to crack it. Why has he never heard of it.

Merton smiled mysteriously and said, "do you know how Li Bing and his son built Dujiangyan?"

When Lao Zhang was stunned, he suddenly realized: "water diversion mouth, flying sand weir!"

"What is Feisha weir!" Fubo on one side didn't understand.

Lao Zhang tou explained: "it is said that when Li Bing and his son built Dujiangyan, they were faced with endless river water and were helpless. Finally, they built Feisha weir by filling pebbles in bamboo cages.

Fubo suddenly said, "young master, what do you mean is that we also use pebbles to pad up the pier and expose it to the water before building the pier?"

"No, it's the Yangtze River with fast flowing water and deep water level. At the moment, we are just in Qujiang River with gentle water potential. Don't use pebbles. Find me the strongest granite and polish it into squares or strips. As long as the Mohist machinery can be transported and transported to the greatest extent, we must lay a solid foundation. If this method is successful, it will be successful However, it will change the history of Chinese bridges, which will benefit the people all over the world, and the travel will no longer be blocked by rivers. "Merton said proudly, and directly ordered to overcome eternal problems at all costs.

"Yes, young master!" Lao Zhang took orders solemnly.

Although Merton's idea is very rough and there is still a lot of preparatory work to be done, it is not impossible for the existing Mohist technology.

With the arrival of Merton, the construction of Qujiang bridge officially began. With the strong mobilization ability of Mojia village, a large number of materials were transported to Qujiang bridge from around Chang'an city.

Under the command of Lao Zhang tou, dredge the silt and determine the foundation. Every foot close to the water surface will be repeatedly tamped by the Mohist children inch by inch. Be sure to ensure that the foundation is firm.

It can be said that the news of pile driving in the center of the river in Mojia village violated the principle of building a bridge. Such abnormal behavior immediately aroused the idea of the people in Chang'an and soon spread all over the city. A large number of people came to watch and talk about it every day.

"Is it possible to set up piers in the river?" many people wondered.

However, more people said with confidence: "it is impossible for others, but it is not impossible for Mohists!"

The people of Chang'an City have seen too many miracles of the Mohist family. When they see the abnormal behavior of the Mohist family, they don't have much reaction. Anyway, they just need to wait for the results. They believe that the Mohist family will certainly give him a surprise.

"Building piers in the river?"

The storm naturally spread to Li Yun's ears. When he heard the news, he was stunned.

"The Mohist school is nothing but a false name. How can we know how to build bridges! How to build piers in the river!" the old servant sneered and sniffed.

"No! Although Mojia Zi has no experience in building bridges, there are many skilled craftsmen in Mojia village. They can't be underestimated. Just keep staring!" Li Yun shook his head,

However, he had a personal contact with Merton and heard all the miracles of the Mohists. Naturally, he didn't think that the Mohists would make such a big mistake.

The old servant said proudly, "so what? When it comes to building the bridge, the master is the best in the world. Which one in Mojia village can compare with it? Even Lao Zhang, who is known as the head of craftsman in Mojia village, should be willing to bow down."

Lao Pu people have been with Li Chun for some time. They worship Li Chun very much. Naturally, they doubt the Mojia village like a dry duck.

However, with the passage of time, with a large number of human and material resources in Mojia village, the project of Mojia village will work overtime soon! When the foundation laid in Qujiang River surfaced, the whole city was a sensation.

"The Mohists really built the bridge foundation in the Qujiang pond." many people exclaimed. Everyone who has some common sense knows the difficulty.

"What is this? According to me, this is probably the most surprising thing that the Mo family has done." more Chang'an people can't deny it. It's not surprising that the people in Chang'an City have seen what strange things the Mo family has done.

Many people immediately came to the Qujiang bridge to watch the foundation that came out suddenly in the river.

"It's said that the foundation is all granite transported from Mojia village. It's very strong. It's more than enough to be used as pier foundation."

"I said, if you are not sure, how can the Mexican family do it?"

"From the beginning, I believed in mojiazi."

……………………

Almost everyone looked disapproving, as if all this was in his expectation. Only Li Yun in the crowd saw the abrupt foundation in Qujiang River. His eyes shrank and his face gradually became dignified.

The old servant on one side sneered: "Young master, don't worry. The young master has won the bet. The reason why mojiazi tried so hard to build piers in the Qujiang pool is that he can't repair the bridge. In those days, the master Zhaozhou Bridge was twenty feet long and more than ten feet across the river. The world was amazed and praised it as the first bridge in the world. Today, the length of Qujiang bridge is similar to that of Zhaozhou Bridge. Mojiazi knows that he can't surpass the old man My Lord, the pier is selected. In this way, the two piers can only meet for eight feet. The young master has won the true legend of my Lord. He uses a single hole arch bridge, which is longer than the Zhaozhou Bridge. This time, the Mohist school will lose. "

Li Yun nodded silently. Since mojiazi adopted the pier, he would naturally want to shorten the bridge body. However, when he saw Merton's appearance, some bad feelings always came to his mind.
