Chapter 252
The reason why Chencang Road and Qishan Road will become the ancient roads into Sichuan is because the destination they reached – Hanzhong was under the jurisdiction of Yizhou during the Qin and Han dynasties, so they naturally became the ancient roads into Sichuan.
But the real road into Chengdu Plain is Jinniu Road and Micang Road.Several small boats went northward on the Jialing River, and Su Yun saw many boats passing by on the river. When Su Yun looked around, he saw boats going down the river. These boats were often filled with all kinds of gravel.
And some boats that go upstream are completely different from those that go downstream. Some are empty boats, while others are loaded with explosives and other building materials.
The number of boats is very large, and they come and go. They are going back and forth. The boats are still going north on the Jialing River, and Su Yun is watching these transporting boats.
These ships do not need to look to know that they are helping to build the road.
At this time, when he retracted his gaze, Chen Mingshu looked at him and said, “The Jialing River, which is the area south of the Baishui River, has a good shipping capacity.
The shipping capacity of the area north of the Baishui River is very poor, and the river surface will freeze in winter, so it does not have large-scale shipping capacity. ”
Saying that, there is some helplessness on the face, this is also something that can’t be helped, and the location determines this.
Once the river surface freezes, water transportation will start to be troublesome, and you can’t break the ice and move forward!
If the northern Jialing River also has good shipping capacity, the road into Sichuan will not be so difficult.
Su Yun nodded when he heard the words, which is understandable, after all, there are old forests in the mountains.
Moreover, it is also affiliated to Gansu. The temperature in winter is very low and very cold. The temperature is often around minus ten degrees, and freezing is also a normal thing.
Once it freezes, the waterway will become troublesome, and things will definitely be delayed.
At this time, the boat of the two gradually came to a few hundred meters in front of the Thousand Buddha Cliff.
When he came here, Su Yun obviously felt that the water was starting to become more turbulent, the speed of the boat became slower, and it became difficult for the people on the bow to paddle.
Su Yun looked out curiously, and only saw that there were many depressions and broken places on the mountain on the right at this time. Burnt black can also be seen above.
Obviously, this place has been bombed and collapsed a lot, and there are still many workers who are using tools to expand the road into the mountain.
Su Yun looked around and saw that there were still a lot of workers, and they were all using tools to knock on these hard-looking walls.
The workers put the crushed stones on the gondolas, which were then loaded onto the boats he had seen before.
When they are almost loaded, these ships will send the gravel away to Yun.
Some workers put heavy wooden boxes one by one on the riverside and sank.
Su Yun looked at it, but he knew the reason why they did this, and there was another method involved.
He could see that there were some rock formations that were somewhat hard, and the location of these explosions was only charred and had no other effect.
While Su Yun and the others watched, the boat was moving forward.
Chen Mingshu also looked over at this time, and after looking at it for a while, he said slowly, “This road is really too difficult to build.
After receiving your project at the end of June, I urgently mobilized manpower to make detailed planning and arrangements for this section of the road.
Combining the previous survey data for planning, now it takes about a month to start construction, but the width of the road cut out is still limited.
A lot of explosives are still used for fixed-point blasting, but the rock formations in some places are too hard.
We blasted it with explosives, but it was useless to burn it with fire. Finally, we thought of a way to use the caisson method to build bridge columns and extend part of the road to the river surface, but we dared not extend too much.
The Jialing River is related to shipping and can only be extended partly, and the remaining part can only be slowly excavated on the rock wall. ”
These are also things that can’t be helped, although they have made very detailed planning and arrangements for this section of the road.
But after getting started, I realized that it was more difficult than I imagined.
In some places, they can’t dig if they want to dig, and they have switched to different methods. Now they can only find a more suitable method to deal with.
The caisson method is temporarily the most suitable for them, but at the same time this method also has disadvantages.
“Thanks for your hard work!”
Su Yun heard the words and said softly, he can understand that the road into the river is difficult to build, and he understands this very well.
It will be useless to fry TNT in later generations, but one can imagine how difficult it is here.
In the end, in desperation, the only way to get through this road into Sichuan was to slowly grind with a water cutter.
With such high technology, it takes time and effort to grind slowly.
It is indeed more difficult to build now without much mechanical help.
Otherwise, Chen Mingshu would not have said the price of 300 million yuan when he first estimated.
The current 300 million is so valuable!
At that time, he invested in the school city and the industrial park in Lu’an, and these projects added up to less than 100 million in the early stage. It is conceivable.
After the two boats passed here, they walked forward for about 200 meters.
At this time, Su Yun could see at a glance that a group of workers were drilling rock formations on the mountain with tools.
There are a lot of people here. Su Yun looked around and visually estimated that there were about a thousand people here.
These people are also desperately building, and the reason why so many people gather here is because of the particularity of this section of the road.
Chen Mingshu said at this time: “This road is difficult here, to meet the road standards of Huayin Company,
It’s still good to have to chisel the road from the mountain little by little.
This place was originally at the foot of the mountain, the mountain was not high, and the front was on the ridge, and only tunnels could be dug. ”
It is not appropriate to use explosives or anything here, and the workers can only dig out the road little by little.
But here is all good, and there are more difficult places in the previous paragraph, where the natural danger lies.
Su Yun nodded after hearing this, he naturally knew the difficulty of building this road.But it is indeed hard work for these workers. Using these tools to dig a little bit, it is really a physical job.
And Chen Mingshu looked at the front, his eyes were very deep, he slowly said: “Actually, these are quite good to tell the truth,
The most difficult part is the Feixian Pass in front, which is the real natural danger. At present, there are more than 100,000 workers in the entire Feixian Pass, and that is the real cliff.
The 857 cliffs on the riverside are nearly 100 meters away from the river surface. The most important thing is that these cliffs are almost vertical.
In addition, the gap between each mountain is very large. The Ministry of Communications gathered all the forces to come up with the water-shooting method.
The steel ingot bridge piers are driven into the bottom of the river, and then the steel ingot bridge piers are connected. The operation platform is first built, and finally the cliffs are excavated. ”
Chen Mingshu said and shook his head slightly, he felt quite difficult just talking.
The excavation of Feixianguan in this way is a relatively complete method that the Ministry of Communications came up with after thinking for a while, and there is no other way.
Su Yun frowned slightly as he listened, he knew how difficult it was just by listening.
Even though this section of the road is only over 170 kilometers long, it is many times more difficult than building a road of over 1,000 kilometers in the northern plains.
Even the Ministry of Transportation, which specializes in building roads, is racking their brains for what to do here.
If it were someone else, I’m afraid I wouldn’t be able to think of a way to deal with it.
Su Yun looked at Chen Mingshu at this time and said, “Are you going to use steel ingot bridge piers from now on?”
He thinks that it is not impossible to use rigid ingot piers, but this involves other problems.
Chen Mingshu shook his head and said, “Steel ingot piers are only a part. Bridge experts say that whether it is steel ingot piers or reinforced concrete piers,
It will need maintenance in the future, or even a new one. This road is too difficult to build, so we need to consider the issue of future maintenance.
Therefore, they use a combination of steel nail piers and concrete piers. In the Feixianguan area, two types of piers will be used in parallel.
And the density is high, there will be four piers every 50 meters as support.
In addition to these, there is also the mountain side, considering that these areas are rainy in summer,
The side of the backing needs to be protected with reinforced concrete, otherwise, once the landslides, it will be a disaster for this road. ”
Naturally, it is not so simple to use steel ingot piers here.
Bridge experts have considered many problems, so two types of piers are used in parallel, so that both can be taken into account.
Chapter 203: The Difficulty of Shu Dao, Difficult to Go to the Sky
Su Yun and Chen Mingshu went upstream against the Jialing River. Along the way, Su Yun’s attention was basically on these hard-working workers, watching them working hard to build this passable road.
And basically every few hundred meters, a group of workers are working on the cliff. None of these workers are idle. All of them are working hard, but the progress is worrying.
It was noon after seeing this all the way, Su Yun and the others did not choose to stop, and even if they chose to stop, there were no people. They ate some of the dry food they brought and continued on their way.
In the evening, Su Yun and the others arrived at a place called Xiatang Village. The population of this Xiatang Village was not large. Su Yun and Chen Mingshu walked into Xiatang Village.
“I’m afraid I’ll be staying here tonight.”
Chen Mingshu said with a smile, but he didn’t take it seriously. He had had this experience before, so he looked at Su Yun, but he was afraid that Su Yun would not be used to it.
“For the time being, I can only trouble the villagers here!”
Su Yun said with a smile, he doesn’t care about it. Anyway, he sleeps wherever he sleeps. He doesn’t choose, just have a tile to cover his head, and he can’t find a hotel or the like in Xiatang Village, and he can’t rent it if he wants to. .
When Chen Mingshu heard the words, he asked his men to go to the people’s house in the village to ask if they could stay overnight. Soon Chen Mingshu and Su Yun stayed at a house called Old Litou. Old Litou looked at Chen Mingshu and Su Yun with expressions on their faces. Smiling and enthusiastic.
He pulled the two of them into the house and said with a smile, “I haven’t had guests at home for a long time, old man, I’m going to kill a chicken.”
Sichuan people are all hospitable. After the old Li’s chief general Su Yun and Chen Mingshu invited them in, they immediately decided to kill chickens to entertain them.
Hearing this, Su Yun quickly grabbed Old Li’s head and said, “Uncle Li can’t do it. Keep the chicken, we have the meat here.”
He naturally felt Old Litou’s enthusiasm, but he knew that the chickens in Old Litou’s house were probably reluctant to eat at ordinary times. As a result, after seeing them, he hurriedly slaughtered them to eat them, which was not acceptable.
Moreover, his guards also brought meat here, and it happened that these ordinary people were willing to sleep with them.
He immediately called a soldier and said, “Let’s distribute all the meat you bring to the people in the village as a reward for our overnight stay tonight.”
Anyway, they couldn’t finish the meat, so they regarded it as a part of their heart to repay the people in the village.
The soldiers went to the meat immediately after taking orders, while the other soldiers of the guard were helping the common people to cook dinner.
At this time, Su Yun and Chen Mingshu were sitting and chatting outside the house. Life in the countryside was really good, and the mood of the two of them relaxed a lot.
“Minister, when do you think this road will be repaired?”
Su Yun looked at the smoke from the kitchen in the distance and said casually. He looked at this road today, and felt that it had just begun. Although it has been a month, the amount of work is indeed huge.
Chen Mingshu folded a grass next to him and said slowly: “It’s really hard to say, but based on the current progress, it is estimated that it will take a long time~¨.”
