Chapter 394 Hard Rock Tunneling Machine

On the west bank of a certain river, in the westernmost part of a certain mountain range, Gaoli Mountain is like the emerald of the Southwest Province, quiet and dazzling.Driving up the mountain, thousands of rocks are beautiful, clouds are steaming and rosy, one of the longest railway mountain tunnels in Southwest China, the construction site of Gongshan Tunnel of Lixi Railway is in the mountains.

The Lixi Railway has a design speed of only 120 kilometers per hour and a total length of only 330 kilometers.If only measured from the length and speed, it seems to be just an insignificant "short horizontal" in the territory of Huaxia Railway.

However, the value of Lixi Railway cannot be ignored.Along the Lixi Railway, there are more than 10 ethnic minority areas such as Bai, Yi, Hui, Lisu, Miao, and Naxi. After completion, the travel time between two prefecture-level cities in the southwest will be shortened from the current six to seven hours to about 3 hours.

As a poverty alleviation line, national unity line, and international cooperation line, the construction of the Lixi Railway is urgent, and the 14.5-kilometer Dagongshan Tunnel is an obstacle that this railway cannot bypass.

这处隧道仅进口段就穿越11种岩性、7条断层，出口段则穿越8种岩性、5条断层，即便24次选线、3次完善设计，目前仍需面对世界级的“三高”挑战。

Riding in the off-road vehicle, Liang Zhijian was still thinking about the difficulty of building this tunnel.

The point is, apart from the longest tunnel on the Lixi Railway, there are dozens of other long and short tunnels, and the amount of tunnel excavation is very large.

"I hope Jiuzhou Heavy Industry's shield machine can meet our requirements." Liang Zhijian thought in his heart.

Ever since he received a call from Xie Zhenhua last night, Liang Zhijian didn't fall asleep for almost the whole night.On the one hand, it is exciting. I did not expect that there is finally a company in our country that can produce large-scale shield machines.Another aspect is the fear of disappointment.

Worried that he rushed to Shenhai City full of hope, but the shield machine of Jiuzhou Heavy Industry was not as good as Xie Zhenhua said in the phone call, and could not meet his construction needs.

The off-road vehicle set off along the mountain road, and after only driving about a dozen kilometers, Liang Zhijian received a call from Li Huakun, the general manager of the railway engineering project department.

During the phone call, Li Huakun said anxiously: "Boss Liang, our 'Robins' is stuck again, and it is estimated that it will stop working for at least 20 days."

what!
Liang Zhijian's expression changed slightly. "Robins" is an imported shield machine with a diameter of 6.39 meters, which is under construction for tunnel excavation. Since its construction, it has been stuck twice, and each time it gets stuck, it must be shut down for at least 20 days.

Unexpectedly, it got stuck again. It was really raining all night due to a leak in the house. When it was needed for tunnel excavation, it actually dropped the chain again.

Xiao Liu was sitting in the co-pilot position of the off-road vehicle. He probably heard the content on the phone. He turned his head and said: "Boss, the cumulative excavation length of this 'Robins' is only 900 meters, and it is actually the third time that it got stuck. ,Why……"

Liang Zhijian was helpless, and sighed. This "Robins" was imported from abroad at a high price. It was one of the main shield machines for the construction of the Lixi Railway Tunnel. maintenance.

During the phone call, Liang Zhijian instructed Li Huakun to speed up the repair of the equipment and get this "Robins" back to work as soon as possible.

During this phone call, Liang Zhijian thought more strongly in his heart, Jiuzhou Heavy Industry, don't let me down, we really need a large shield machine urgently.

……

Deep Sea City.

Taking the plane, Tang Fei came here again.However, this time, he was not alone, but accompanied by Li Xueyan.In order not to be separated from Tang Fei, Li Xueyan asked for leave and came here together.

After walking out of the airport, Tang Fei saw the people and the car who came to pick him up, he held his girlfriend's hand and said, "Come on, let's get in the car first."

It was Liu Shiwei who came to greet him. Knowing that Brother Fei was coming to Shenhai City again, he insisted on coming to greet him at the airport, so Tang Fei didn't insist either, so let him come to greet him.

"Brother Fei!"

Liu Shiwei walked over quickly. He hadn't seen him for a while, and he seemed to have gained some weight. When he walked, the fat on his body trembled.

Tang Fei smiled and said jokingly: "Fatty, it seems that your life is very nourishing, and you have gained a lot of weight."

Li Xueyan covered her mouth and smiled lightly.

Liu Shiwei scratched his head and said with a smile, "No, no, I've only gained a few catties this month." After speaking, he warmly greeted Li Xueyan, "Sister-in-law is here too."

Li Xueyan's face flushed slightly, she was a little embarrassed to say "sister-in-law", and she was secretly happy again, sweetly.

Seeing that his girlfriend was a little embarrassed, Tang Fei quickly waved his hands and said, "Come on, get in the car, we have to go back to the big villa first."

"Okay." Liu Shiwei agreed loudly, and enthusiastically opened the car door, inviting Tang Fei and Li Xueyan to get in the car. Then, he drove the car himself, left the airport, and headed for his big villa.

……

Jiuzhou Heavy Industries.

Zhu Yifeng is in the assembly plant. The huge plant is different from before. Now there are many workers busy, and there are also large shield machines starting to assemble.

One big and one small, a total of two.

The small one is relatively small, but it is actually not small, with a diameter of 6.3 meters. After assembly, it will reach 65 meters in length and weigh nearly 500 tons.

The other one is much larger. It is a veritable "Big Mac". Its length will reach 230 meters, its excavation diameter will reach 9.03 meters, and its weight will be 1900 tons. It is specially designed for railway tunnel construction and used for mountain tunnels. The large shield machine for excavation is also a hard rock excavation machine.

There are a total of two large shield machines, and the assembly of the first one has already begun. Zhu Yifeng is obviously quite satisfied with the progress.

This shield machine with a diameter of 6.3 meters will be manufactured in a row for several sets, because it already has the first order, and Shenhai City has ordered several sets for the construction of the Shenhai City subway tunnel.

"Well, the boss will come to Shenhai City today, so he should have arrived." Zhu Yifeng thought in his heart.

Originally, he volunteered to go to the airport to pick up Tang Fei and go directly to Jiuzhou Heavy Industries, so that Tang Fei could take a look at the two shield machines that had entered the final assembly.

However, after the phone call, Tang Fei said with a smile that he was a bit late and someone had already taken the lead, so he didn't come to the airport to meet him.

Zhu Yifeng even thought in his heart, could it be Lao Yang? He knew that the boss was coming to Shenhai City, so he called early and asked to pick him up at the airport.

In fact, it wasn't Yang Chenglin, but Liu Shiwei from Wanheng Real Estate. Zhu Yifeng didn't think about this.Now, Tang Fei has arrived at his big villa, maybe, he will come to Jiuzhou Heavy Industry tomorrow.

He looked at the two large shield machines in front of him with satisfaction, as if they were two giants.Zhu Yifeng also thought with satisfaction, this factory building is good, high enough, big enough, not to mention the 9-meter shield machine, even the super shield machine with a diameter of more than ten meters in the future can be produced here.

The workers are working in an orderly manner, and there are technical staff to guide them.

The assembly process technical data is ready-made, all from the system, how to assemble, the process data is clearly written, what to do in the first step, what to do in the second step, completely follow the data.

The crane in the factory building is hoisting a big thing, and it is slowly, slowly, and carefully aligning and assembling it. This is a large part of the shield machine.

"Okay, come down a little more!"

"A little bit to the right."

Someone was directing loudly, and after several workers saw the alignment, they began to assemble this large part, and everything was in order.

After watching the final assembly site, Zhu Yifeng thought to himself, judging from the current situation, the successful assembly of the first large-scale shield machine should be completed much earlier than expected. The first one can be assembled without the expected [-] days.

the next day.

At around [-]:[-] in the morning, only a little later than the employees went to work, Tang Fei drove himself to Jiuzhou Heavy Industry alone.

I went to Shenhai City yesterday morning, and I didn't come here in a hurry. I mainly took a rest with my girlfriend, went out for a stroll in the afternoon, and came to Jiuzhou Heavy Industry this morning.

Choosing to come to Jiuzhou Heavy Industry first instead of Jiuzhou Electronics, of course, not only wanted to see the shield machine entering the final assembly, but also knew that Liang Zhijian and others would come this morning.

Last night, Tang Fei also specifically checked the Chalixi Railway on the Internet. He knew that although this railway line is only more than 300 kilometers long, the construction is not small, especially the excavation work of the tunnels. Among them, the Dagongshan Tunnel, With a length of 14.5 kilometers and complex geological conditions, a very advanced hard rock tunnel boring machine is required, which is also one of the shield machines.

Its Jiuzhou Heavy Industry is trial-producing a hard rock boring machine with a diameter of more than 9 meters, which is specially tailored for railway tunnel construction.

Tang Fei thought in his heart that his hard rock boring machine can be placed on the Lixi Railway to see how it performs.

Tang Fei wanted to have a good talk with Liang Zhijian, and also wanted to use this to open up the domestic railway tunnel shield machine market, so he went to Jiuzhou Heavy Industry early today.

"Boss, our 6-meter and 9-meter large shield machines have entered the final assembly process and are being assembled in our huge final assembly workshop. Do you want to go and have a look now?"

Tang Fei raised his hand to check the time, and said, "No hurry, wait a little longer, we have some guests, they should be arriving soon."

Zhu Yifeng said in surprise: "Boss, you are talking about Chief Engineer Liang Zhijian and his group."

"Yes, they should have arrived in Shenhai City, and they will come to Jiuzhou Heavy Industry this morning." Tang Fei said.

Sure enough, it didn't take long. Before nine o'clock in the morning, Liang Zhijian and his group of five arrived at the gate of Jiuzhou Heavy Factory Area by car.

After getting out of the car, Liang Zhijian looked at the factory area, then at the label of Jiuzhou Heavy Industries, took a deep breath, tried to calm down his agitated mood, and thought in his heart, we are here, don't let us Disappointed, here, there must be the kind of large shield machine we hoped for.
