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

For a while, the entire Mo family was worried, and they had no skills but were helpless.

"Young master, how about we also build an arch bridge, with the existing technology of the Mo family, it is not too difficult to build an arch bridge, the old man has already seen the bridge built by Li Yun, and it is not difficult to beat him." Lao Zhangtou said with confidence.

Don't look at Li Yun, who thinks that after Li Chun, he has mastered the most advanced bridge repair technology, but in terms of the current Mo family's technology, he is already a lot behind, and he is confident that he will surpass him.

Merton shook his head and said: "Your Majesty ordered the Mo family to repair the bridge not just for this Qujiang bridge, but for the preparation of a wider and longer river. What about the Huai River, what about the Yellow River? Do they all use arch bridges?

Lao Zhangtou shook his head again and again, the arch bridge is only suitable for small rivers, if the river is too wide, there is no way to build an arch bridge, which is also the reason why large rivers cannot be built in this era.

"But at present, not only has the Taoist Waidan sect not developed cement that can be solidified underwater, but the silt at the bottom of the river is very deep, and if the piles are forcibly erected, it is only afraid that the foundation will be unstable, and it is impossible to erect bridge piers." Lao Zhangtou frowned and thought deeply, if the bridge is unstable, even if it is forcibly built, it will be a ruined bridge.

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

"Lay the foundation on the water?" The old man looked at Merton incredulously as if listening to a book from heaven.

Merton smiled mysteriously and said: "In fact, to solve the problem of building bridges in the water, the ancients have already solved it, but we haven't found it!" ”

"The ancients have cracked it!" Lao Zhang was confused, the ancients already had a way to crack it, so why had he never heard of it.

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

Lao Zhangtou was suddenly enlightened, and suddenly realized: "Water divider, flying sand weir!" ”

"What is a flying sand weir!" Fauber on the side was puzzled.

Lao Zhangtou explained: "According to legend, when Li Bing and his son built Dujiangyan, they were at a loss in the face of the endless river water, and finally used bamboo cages to load pebbles to build a flying sand weir.

Fu Bo said suddenly: "What does the young master mean is that we will also use pebbles to raise the bridge piers and expose them to the water before building the bridge piers?" ”

"No, it is the Yangtze River with turbulent water flow and deep water level, and at this moment we are just waiting for the water to be gentle, the Qujiang River in the dry period, don't use any pebbles, find me the strongest granite, all polished into a square or strip, as long as the Mojia machinery can be transported, the maximum amount of transportation, must be the foundation firm, if this method is successful, it will definitely change the history of Chinese bridges, the people of the world will benefit from it, and travel will no longer be blocked by the river." Merton said proudly, and directly ordered that no matter the cost, we must overcome the eternal problem.

"Yes, young master!" Lao Zhangtou solemnly received the order.

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

With the arrival of Merton, the construction of the Qujiang Bridge officially began, and under the strong mobilization ability of Mojia Village, a large number of materials were transported from around Chang'an City to the Qujiang Bridge.

Under the command of Lao Zhangtou, dredging and determining the foundation, every foot close to the water surface will be repeatedly tamped inch by inch by the children of the Mo family, and the foundation must be firmly ensured.

The news that Mojia Village was piling in the center of the river can be said to have violated the principle of building a bridge, and such an abnormal behavior immediately aroused the idea of the people of Chang'an, and soon spread throughout the city, and a large number of people would come to watch and discuss every day.

"Is it possible to erect a bridge pier in the middle of the river?" Many people wondered.

However, more people were Merton full of confidence and said: "This is impossible for others, but for Mo Jiazi, it is not impossible!" ”

The people of Chang'an City have already seen too many miracles of the Mo family, and when they see the abnormal behavior of the Mo family, they don't have much reaction, anyway, they just need to wait for the result, they believe that the Mo family will definitely give him a surprise.

"Building piers in the middle of the river?"

The wind and rain in the city naturally reached Li Yun's ears, and when he heard the news, he couldn't help but be stunned.

"The Mo family is just a false name, how can he know how to build a bridge! How to build piers in the river! The old servant sneered and sneered.

"Nope! Although Mojiazi has no experience in repairing bridges, there are many skilled craftsmen in Mojia Village, which should not be underestimated, just keep staring! Li Yun shook his head and said,

He had personally fought with Mo Dun, and he had heard all kinds of miracles of the Mo family, so he naturally didn't think that the Mo family would make such a big mistake.

The old servant said proudly: "So what, when it comes to repairing bridges, the old man is the first in the world, and there is no one in Mojia Village who can compare, even the old Zhang Tou, who is known as the head of craftsmen in Mojia Village, has to bow down." ”

Lao Puren had been with Li Chun for a period of time, and he admired Li Chun very much, so he was naturally very suspicious of the landlubber-like Mojia Village.

However, with the passage of time, under the large amount of manpower and material resources of Mojia Village, the project of Mojia Village worked overtime, and soon! When the foundation laid in the Qujiang River surfaced, the city was suddenly full of sensations.

"The Mo family really laid the foundation of the bridge in Qujiangchi." Quite a few people exclaimed. Anyone with a little common sense knows that the difficulty of this can be imagined.

"What is this? According to me, this is probably the most surprising thing that Mo Jiazi has done. "More people in Chang'an can't deny it, and it is not surprising that the people of Chang'an City have seen what Mo Jiazi has done.

Many people suddenly came to Qujiang Bridge and came to watch the foundation that abruptly emerged in the river.

"I heard that this foundation is all granite transported from Mojia Village, which is very strong, and it is more than enough to make the foundation of the bridge pier."

"I'll just say, if you don't know what you're sure about, how can the Mo family do it."

"From the very beginning, I believed in the Mo family."

……………………

Almost everyone looked unimpressed, as if all this was expected by him. Only Li Yun, who was in the crowd, saw the abrupt foundation in the Qujiang River, and his eyes couldn't help shrinking, and his face gradually became solemn.

The old servant on the side sneered: "Young master, don't worry, this bet has been won by the young master." The reason why Mo Jiazi worked hard to build bridge piers in Qujiang Pond is nothing more than that the bridge repair technology is not good, when the old man Zhaozhou Bridge, the bridge is twenty zhang long, the net cross of the river surface is more than ten zhang, the world is amazed, known as the first bridge in the world, the length of today's Qujiang Bridge and Zhaozhou Bridge is similar, Mo Jiazi knows that it is impossible to surpass the master, so that the bridge pier is selected, so that the two bridge piers get together between each other but eight zhang, and the young master is deep in the true biography of the master, the use of a single hole arch bridge, the length has exceeded the Zhaozhou Bridge, this time the Mo family will undoubtedly lose. ”

Li Yun nodded silently, since Mo Jiazi used bridge piers, he naturally wanted to shorten the bridge body, but when he saw Mo Dun with such fanfare, there were always some bad feelings in his heart.
