God-level industrial master

Chapter 397 Severe Test
Liang Zhijian looked at the big guy in front of him expectantly, and thought in his heart, the technicians of Jiuzhou Heavy Industry have worked hard. In just a few days, the big guy in front of him has been assembled and can be put into use.

Li Huakun, the general manager of the project, said loudly: "Director Liang, it's finally healed, we can try how this big guy is!"

"Well, I'll try it right away."

In front of you is the Dagongshan Tunnel, which will reach a length of 14.5 kilometers. It is the longest among the dozens of tunnels in the entire Lixi Railway, and it is also the most difficult project.Because the geological conditions are very complicated, only a few hundred meters have been excavated so far, and the entire project has almost just begun.

The previous "Robins" always went on strike one after another, and "knife jam" happened at every turn, and every time "knife jam" occurred, it often had to stop working for more than 20 days.

For this "Robins" with a diameter of 6 meters, both Liang Zhijian and Li Kunhua were very disappointed and very annoyed.

Now, the "Pioneer" manufactured by Jiuzhou Heavy Industries has been assembled and ready to use.Li Huakun asked for instructions: "Chief engineer Liang, should this large shield machine be put into construction in the pilot tunnel or in the main tunnel?"

This must be considered clearly.

The construction difficulty of the pilot tunnel is much lower, and the geological conditions are far less complicated.The main tunnel is different. It will pass through many fault zones, hot spring zones, etc. The geological conditions are very complicated, which is a huge test for the construction shield machine.

At this time, Liang Zhijian seemed a little hesitant, thinking about some performances and parameters of the "Trailblazer".

"Pioneer" has an overall length of 230 meters, a weight of 1900 tons, and a cutterhead excavation diameter of 9.03 meters...

After thinking about it, Liang Zhijian was still a little undecided, so he simply took out his mobile phone and called to ask Tang Fei for advice.

The call was connected quickly, and Liang Zhijian explained the matter again, and then said: "Mr. Tang, what is your opinion, this shield machine is to carry out pilot tunnel construction for a period of time first, after the running-in period and adaptation period , and then enter the main cave for construction, or enter the main cave for construction at the beginning.”

In order not to delay the construction period, in fact, Liang Zhijian's idea was to enter the main tunnel for construction, but he was worried that if something went wrong with the shield machine in the construction of the main tunnel, it would be troublesome.

Tang Fei's hearty laughter came over, and he said confidently: "Director Liang, I suggest entering the main cave for construction."

Liang Zhijian reminded: "For the construction of the main tunnel, the geological conditions are much more complicated, and the project is much more difficult. It will pass through earthquake zones and geothermal groups along the way, which is a huge test for the shield machine."

Tang Feidao: "It's a mule or a horse. You have to take it out for a walk and enter the main cave for construction. I think our 'Pioneer' can withstand the test. Also, please rest assured that during the construction of the main cave, Our technicians will follow up the service throughout the whole process, and once the machine is damaged and needs to be repaired, all costs will be borne by us.”

Advocating to enter the main tunnel construction with complex geological conditions, Tang Fei not only has confidence in the "Pioneer", but also wants to truly test his own shield machine.

If everything goes well in the construction of the main tunnel and the Dagongshan Tunnel can be successfully opened, it will definitely bring a huge advertising effect and win a good reputation for its shield machine.

The shield machine imported from abroad may not be competent for the construction task. The shield machine of our own has been successfully completed and the Dagongshan Tunnel has been successfully opened. It will definitely play a huge advertising role in the entire field of Huaxia Railway Tunnel Construction. Uncertain, many media will report and advertise their own shield machines for free.

Based on this consideration, Tang Fei advocated that the "Pioneer" enter the main cave for construction.

After making the phone call, Liang Zhijian waved his hand and said, "Enter the main tunnel for construction, and make preparations for entering the tunnel now. I also want to see how the shield machine performs."

Li Kunhua said: "Okay, I'll make arrangements right away."

In this way, the "Pioneer" is ready to enter the main tunnel, while the previous "Robins" can only make way for the construction of the pilot tunnel which is much less difficult to construct.

Today's weather is good, it's a rare sunny day, the sun is hanging in the sky, the sky is blue, and the air is not bad, as if the air is full of negative ions, every breath gives people a refreshing feeling.

At the entire construction site, almost everyone knew that the "pioneer" would enter the main cave for construction, and many people came to witness this historic moment.

Several technicians and workers from Jiuzhou Heavy Industry re-checked the "Pioneer", and after confirming that it was correct, this large shield machine began to enter the main tunnel under everyone's gaze.

Slowly, slowly, the "Pioneer" began to enter the hole.The current depth of the main hole is only a few hundred meters, and soon after, the "Pioneer" reached the working face.

The machine starts up.

The roar sounded in the main cave. Because the depth of the main cave was not large, people outside the cave could hear this roar, and many people became excited.

"Listen, it should already be working."

"This is our first domestically produced large-scale shield machine. I don't know how it will perform."

"..."

Many people stretched their necks and looked into the main cave.Liang Zhijian waved his hand and said, "Come on, let's go in and see how it works."

Liang Zhijian and Li Kunhua walked in the front, followed by at least a dozen people. Everyone walked into the main cave together and walked towards the depths of the main cave.

The main hole was dug for one to two hundred meters by drilling and blasting method, and a certain distance was dug with the "Robins" with a diameter of 200 meters. The Pioneer, heard a rumbling sound, and saw a large amount of rock debris being sent out.

"Rumbling", in the dark Dagongshan tunnel, the fuselage is shaking and the noise is deafening. The "Pioneer" hard rock tunnel boring machine is like a giant beast that swallows sand and rocks, burying its head forward, invincible.

"Wow, the speed seems to be fast!"

"Yeah, it seems to be a lot faster than that 'Robins'."

Everyone quickly discovered the difference from the previous ones. The efficiency of this shield machine seems to be very high, and the speed is very fast, at least two or three times faster than the previous "Robins". A large amount of rock debris was sent out. The "Pioneer" is also advancing a little bit.

Seeing this scene, Liang Zhijian became happy and gradually felt relieved. The current performance of the "Pioneer" was just as Tang Fei introduced.

Liang Zhijian thought in his heart, Mr. Tang didn't brag at all, the performance of this shield machine is indeed very good.

Li Kunhua said loudly: "Boss Liang, at this speed, at least a few meters must be advanced every hour. If the road goes smoothly, the Dagong Mountain can be dug through in a few months!"

A tunnel with a diameter of 9 meters and a length of 14.5 kilometers was dug in just a few months. It is unimaginable. Now, this possibility is really possible.

Liang Zhijian stayed in the tunnel for a long time, watching the "pioneer" working with satisfaction, seeing that he had advanced several meters, Liang Zhijian thought in his heart, this is really a monster that swallows sand!
"What, it has advanced more than ten meters, it is impossible!"

"Yeah, how long has it been in the hole, maybe two or three hours, it's so fast!"

"..."

Some information spread to the ears of the workers. Hearing that the excavation speed of the "Pioneer" was very fast, many people couldn't believe it.

But the fact is that the giant sand-swallowing beast has been advancing bravely in the main cave, its speed is not slow at all, and its performance is very good.

One day, two days, three days...

Everyone has become accustomed to the excellent performance of the "Pioneer", and the length of the Dagon Mountain tunnel is also increasing day by day. This giant sand-swallowing beast is heading deep into the Dagon Mountain.

As the chief engineer and chief technical officer of the Lixi Railway, Liang Zhijian did not dare to take it lightly, because he knew that the geological conditions in the Dagong Mountain area were very complicated, and he had to cross many faults and broken zones along the way, as well as many geothermal sites. Spa belt.

In the simple office, Liang Zhijian and Li Kunhua were there, as well as several engineers and technicians from the Dagongshan Tunnel. At this moment, everyone's hearts gradually developed.

The first test is coming soon.

On the wall above the office, there is a general drawing of the tunnel design, on which the location of the "Pioneer" is marked with a red pen, and those fractured and broken zones, geothermal hot spring zones, etc. are also clearly marked on the map .

"Chief engineer Liang, the 'Pioneer' has reached the first fracture zone. I wonder if there will be any abnormal situation."

Some people also said: "Don't let anything happen, this is a fracture zone, and it will be a huge test for the shield machine."

In the entire office, the atmosphere is more dignified!

The phone on the desk rang, Liang Zhijian picked up the phone, and hurriedly said: "I am Liang Zhijian, how is the current situation?"

"Chief engineer Liang, the 'Pioneer' has entered the fracture zone. At present, everything is normal, and it is advancing at full speed!"

"Good, good, good." Liang Zhijian said three good words again and again.After putting down the phone, he said loudly: "Good news, the Pioneer has no abnormalities and is advancing at full speed."

"Oh yeah!"

A young technician shouted loudly and waved his fist vigorously, very happy.Others are pretty much the same.

Liang Zhijian reminded: "Everyone, this is just the beginning, and it will take several days to completely pass through this fracture zone."

Yes, this is just the beginning, and there are no problems at the beginning, but it does not mean that there are no problems during the entire excavation process.

After such a reminder, while everyone was happy, they gradually restrained the smiles and happy expressions on their faces.

Because the "Pioneer" entered the fracture zone, followed by a geothermal hot spring zone, Liang Zhijian was worried that something would go wrong. These days, he stayed close to each other and kept watching the construction of the Dagongshan Tunnel.

After about a few days, what he was worried about was finally discovered.

At this time, the "Pioneer" had just successfully passed through the first fracture zone and was entering the first geothermal hot spring zone. Something happened!

An engineering technician anxiously broke into Liang Zhijian's simple office and said loudly: "Chief Liang, something has happened, please go into the cave and have a look!"

……

There are only two updates today, the first update will be sent first, and the second update will be around 21 o'clock in the evening.
