What Liang Zhijian feared still happened.

The most dangerous thing in the construction of the Dagong Mountain Tunnel is not the fractured and broken zone, but those geothermal hot spring belts. In such a place, not only does there be a lot of hot water, but the water temperature is often relatively high, sometimes reaching 80 or 90 degrees Celsius.

At such a temperature, it can completely burn people to death.

"Chief Engineer Liang, go and take a look, something is wrong!"

The engineer and technician looked anxious, where did Liang Zhijian dare to be the slightest slack, and immediately took a few, quickly entered the Dagongshan Tunnel, and drove to the depths of the tunnel.

The construction of the "Pioneer" has been more than half a month, the tunneling depth has already exceeded 1,000 meters, and the total depth of the tunnel is more than 2,000 meters

"What's going on!"

Seeing several technicians here, Liang Zhijian asked with a face, and he also looked more anxious, at present, the first priority is to figure out the specific situation.

The technical person in charge here said: "Chief Engineer Liang, the situation is very bad, the 'Pioneer' has entered the geothermal hot spring zone, and the water temperature is very high, it has reached more than 90 degrees. ”

What the!

With such a high water temperature, this is incredible. Liang Zhijian's face changed slightly, such a situation did not seem to have been encountered a few times in his career.

Just as he was about to say something, another technician ran over with a deep foot and a shallow foot, and said from afar: "The water temperature has exceeded 100 degrees, and it is still rising!"

Suddenly, many people's faces changed.

We know that under normal pressure, the boiling point of water is 100 degrees, that is, when the temperature reaches 100 degrees, water will boil, and the water temperature will also stabilize at 100 degrees and will not rise again.

If it is under high pressure, then it is not the same, the boiling point of water will be more than 100 degrees, maybe 100 degrees and more, or even higher. At such pressure, the water temperature reaches 100 degrees, and the water does not boil, but continues to rise.

"Walkie-talkie, give me the walkie-talkie, I want to know about the Trailblazer!"

In order to facilitate command and communication, many technicians and command personnel are equipped with walkie-talkies to facilitate communication with each other.

Soon, someone gave the walkie-talkie to Liang Zhijian. Picking up the walkie-talkie, Liang Zhijian said eagerly: "I'm Liang Zhijian, 'Pioneer', how is your situation?",

Soon, a voice came from the walkie-talkie, "Chief Engineer Liang, the 'Pioneer' is working normally, and the number of instruments is also very normal, and it is advancing into the first water gushing belt!"

In such a situation, the "Trailblazer" actually behaved normally!

Many people looked at each other in astonishment, and couldn't believe that the water temperature monitoring data just now would not be fake, this is a typical geothermal hot spring belt, and the water temperature is as high as 100 degrees.

Liang Zhijian said: "How is the water temperature, hurry up and report!"

Another voice came from the intercom: "The meter shows that the water temperature is one hundred and two degrees." ”

Oh my God, the water temperature is more than 100 degrees, which means that the pressure is relatively high, not under normal pressure. "Trailblazer" works at high temperatures and pressures.

Liang Zhijian immediately said: "Pay close attention to the work of the 'Pioneer', and report it immediately if there is any abnormality." ”

After speaking, he immediately said: "Quick, notify the technical staff of Jiuzhou Heavy Industry to arrive and follow their opinions, in this case, whether the 'Pioneer' can continue to work." ”

"Okay. ”

Not long after, the technicians stationed in the Dagongshan Tunnel to track and record the work of the "Pioneer" soon entered the tunnel and paid close attention to the situation of the "Pioneer".

To everyone's relief, despite the very bad situation of the geothermal hot spring zone, the work of the "Pioneer" has been very normal, and it has been digging at full speed, like a bamboo!

Two days later, the "Pioneer" successfully broke through the first hot spring belt, and immediately, Liang Zhijian was relieved and almost gave a thumbs up to the "Pioneer".

In less than 20 days, the "Pioneer" not only excavated more than 1,000 meters, several times more efficient than the previous "Robbins", but also successfully passed through the fracture zone and the geothermal hot spring zone, without being affected at all, and has been rapidly advancing into the depths of the tunnel.

The 14.5-kilometer-long Dagongshan Tunnel needs to pass through seismic zones and geothermal groups, and if the traditional drilling and blasting method is used for construction, every inch is tormented.

Like the imported "Robbins", it has three "stuck knives" in the pilot tunnel construction where the geological conditions are much better and the construction difficulty is much lower, and each "stuck knife" has led to a shutdown of more than 20 days.

If it was replaced by "Robbins", the construction in the main cave with such complex conditions would have been lying on the nest long ago. The Trailblazer has had no abnormalities.

When many railway construction workers are resting, the topic is always inseparable from the "Pioneer" who is working in the Dagongshan Tunnel.

No, at noon, many workers were eating while talking loudly about the "Pioneer".

"I heard one of my fellow countrymen say that the 'Trailblazer' has advanced nearly two thousand meters, and this speed is amazing!"

Immediately, someone said: "Not to mention the speed, what is rare is that it has successfully passed through a broken and broken zone, a geothermal hot spring zone, all of which have passed smoothly without any abnormality." ”

"Doesn't that mean that the Trailblazer is much better than the imported Robbins. ”

Someone scoffed and said disdainfully: "The imported 'Robbins' is just a scum in front of it, do you know, the 'Trailblazer' now has a loud nickname, you don't know!"

"Tell us about it, what kind of nickname?"

"Because the Trailblazer is so violent, many people working in the tunnel call it a tunnel maniac. ”

"Tunnel Maniac, haha, that's too vivid. ”

Many people laughed out loud with joy, this nickname is really vivid, which also shows that the "Trailblazer" is too powerful.

After successfully passing through the first fracture zone and the first geothermal hot spring zone, the "Pioneer" successively crossed the second fracture zone and the second geothermal hot spring zone.

When encountering a broken belt or a geothermal hot spring belt, Liang Zhijian was much calmer, knowing that the "Pioneer" would definitely be able to pass through smoothly.

Sure enough, no one was disappointed when the Trailblazer continued to dig deeper into Mount Dagong, and the tunnel was getting deeper and deeper.

Not only Liang Zhijian thinks so, but Li Huakun also thinks so, the successful completion of the Dagongshan Tunnel must be much earlier than the original plan.

The performance of the "Robbins" in the pilot tunnel was much inferior, and there was another jam, so Liang Zhijian was very angry, and simply ordered the "Robbins" to withdraw from the pilot tunnel and replace it with another large shield machine of Jiuzhou Heavy Industry.

This is the second unit of the "Caiyun", and the first unit was delivered to the city of Changzhou about twenty days ago for the construction of the Changzhou subway tunnel.

Within two days, the second unit of the "Caiyun" arrived at the Dagongshan Tunnel and was put into the construction of the pilot tunnel.

……

Tang Fei had already returned to Qingjiang City.

It's the end of January, and the Lunar New Year is not far away. The operating and production data of Jiuzhou Industrial Group have long been counted.

In 2001, the total revenue of Jiuzhou Industrial Group successfully exceeded 20 billion yuan, reaching more than 24.72 billion yuan, compared with 10.8 billion yuan in 2000, an increase of more than double.

The growth rate is so large, in addition to the expansion of the scale of Jiuzhou motor, creating billions of total revenue, the largest contribution is Jiuzhou Electronics Company, the sales of two mobile phone chips are calculated in tens of millions, in addition, Jiuzhou Metro Company, Jiuzhou Heavy Industry, have a certain contribution to the total revenue.

Two days ago, Tang Fei received a call from Liang Zhijian, who not only told him that the "Caiyun" had begun to enter the pilot tunnel construction, but also that the "Pioneer" who was working in the main cave successfully passed through the fracture zone and the geothermal hot spring zone, and behaved very vigorously.

On the phone, Liang Zhijian not only expressed his deep gratitude, but also happily told Tang Fei that because the "Pioneer" was too violent, everyone became a tunnel maniac.

Hearing this nickname, Tang Fei also laughed happily, the tunnel maniac is really worthy of the "Pioneer".

The "Caiyun" also arrived at Dagong Mountain and began the tunneling, and it is certain that the vigorous performance of this large shield machine will soon win a good reputation and achieve a good influence.

Even Tang Fei was thinking that maybe there would not be much left, and the large shield machine of Jiuzhou Heavy Industry would usher in the third and fourth orders.

A number of domestic railway lines are under construction at the same time, many cities are carrying out subway construction, and the excavation of highway tunnels also needs large shield machines.

Jiuzhou Heavy Industry has two large shield machines successfully put into production, and has also successfully won orders. With the area and scale of Jiuzhou Heavy Industry's factory, it will definitely not only produce and manufacture large shield machines in the future, but will also have other heavy equipment.

For 2002, Tang Fei has his own plan, that is, the scale of Jiuzhou Industrial Group will be expanded, and the total revenue will be increased again, at least more than 30 billion, and strive to reach a scale of 40 billion.

Jiuzhou Heavy Industry and Jiuzhou Metro want to become a new force in total revenue growth, so Tang Fei has begun to think about what the second heavy industry equipment of Jiuzhou Heavy Industry is.

Gradually, Tang Fei had a plan.

thought of a very good piece of equipment, and decided to produce it by Jiuzhou Heavy Industries.

In the next ten years, or even more than 20 years, China will vigorously invest in infrastructure construction, and there will definitely be a large market for such equipment.

Then let it become the second heavy equipment manufactured by Jiuzhou Heavy Industry Group. Tang Fei thought so in his heart.

……

Today's two watches, the second one is sent, thank you!
