In his mind, yesterday's scene came to mind, Zhu Yifeng said: "Ouyang Liang and they arrived at Jiuzhou Heavy Industry at about one o'clock at noon, and as soon as they came, they got straight to the point, wanting to know about our large shield machine." ”

"I was more curious at the time, and asked him how he knew that we had a large shield machine, and he replied, listening to Liang Zhijian, and Liang Zhijian spoke very highly of our large shield machine, and highly recommended our shield machine......"

While listening to Zhu Yifeng's introduction to the situation, Tang Fei thought in his heart, as he expected, with his first large-scale shield machine entering the construction of the Dagongshan Tunnel, a good advertising effect has gradually formed.

Whether it is Liang Zhijian or Ouyang Liang, they all belong to the same system and belong to the Huaxia Railway Construction Group.

The outstanding performance of the "Pioneer" and "Caiyun" in the Dagongshan Tunnel is estimated to gradually spread throughout the domestic railway construction industry, which is much better than spending money on TV advertising.

Zhu Yifeng said: "Yesterday afternoon, I not only took Ouyang Liang and others to our production site to see the processing of various parts of the shield machine, but also the shield machine in assembly. ”

In the assembly plant of Jiuzhou Heavy Industry, the assembly work has been carried out, and the shield machines on the current order will be fully produced and delivered to customers within this or two months.

What Ouyang Liang saw was not only the "Caiyun" with a diameter of 6 meters, but also the "Pioneer" with a much larger diameter.

Zhu Yifeng said: "They looked at the assembly workshop for a long time and learned about our shield machine in detail, and then we sat together and talked about the ordering of the shield machine. ”

"Everything has basically been negotiated, the intention has basically been reached, the formal contract is signed, it should be after the New Year, Ouyang Liang said, he will make a detailed report to his leaders after he goes back, if there is no accident, they will take the initiative to come over after the New Year. ”

After listening to Zhu Yifeng's report, Tang Fei felt good, the third order of Jiuzhou Heavy Industry has eyebrows again, and with the third order, there will definitely be a fourth, fifth, and even Nth order.

Jiuzhou Heavy Industry, which gradually began to mass-produce large-scale shield machines, is sure that in 2002, various large-scale shield opportunities are very hot.

Large-scale infrastructure construction in China, whether it is railways, highways, or subway construction in major cities, requires a lot of large-scale shield machines.

In the past, the technology of large shield machine was monopolized by foreign countries, and the construction of our domestic tunnel can only be imported from abroad at a high price, or the traditional drilling and blasting method can only be used.

Now, Jiuzhou Heavy Industry's large-scale shield machine with excellent performance has come out, and has won two orders, and there will be no fewer orders in the future.

This is true for large shield machines, and the same is certainly true for large bridge erecting machines, and its market is equally huge. Tang Fei advised: "Keep in touch with Ouyang Liang and them, sign this order as soon as possible, and in addition, you should hurry up the trial production of the first bridge erecting machine." ”

"Boss, don't worry, I'll do these things beautifully. Zhu Yifeng assured.

He only stayed in Qingjiang City for half a day, and in the afternoon, he took this USB flash drive full of technical information of advanced bridge erecting machines, and hurriedly returned to Shenhai City.

Needless to say, he will organize technical forces, digest and understand these technical data, and also begin to make some preparations for the trial production of the first large-scale bridge erecting machine.

……

Lixi railway construction site.

In a few days it will be the Lunar New Year, but here, there is not the slightest sign of the New Year, everyone has only one thought, work hard to build, and build this railway as soon as possible.

What makes everyone happy is that one of the obstacles to the construction of the railway, the construction of the Dagongshan Tunnel has been very smooth, this "Pioneer" has been moving forward bravely, more than a month, it has never had any failure, not to mention what "stuck knife" phenomenon.

It is now a real "tunnel maniac", in more than a month, it has successfully crossed a number of broken fault zones, geothermal hot spring belts, and has successfully advanced into the depths of Dagong Mountain, and two days ago, it entered the first rockburst zone.

But it has been working normally, which made Liang Zhijian, who was still a little worried, completely let go, knowing that this small rockburst zone could not stop the progress of the "Pioneer" at all.

What makes Liang Zhijian even happier is that Jiuzhou Heavy Industry is powerful enough, and two large shield machines have arrived at the railway construction site, which are the third and fourth units of the "Caiyun" respectively.

Currently, the two TBMs are working on another tunnel, which is more than 1,000 meters long and less than 10 kilometers from the Dagongshan Tunnel.

Today, Liang Zhijian welcomed an old friend of his, Ouyang Liang, the person in charge of a railway line project. The two were naturally happy to meet.

Liang Zhijian said: "Old man, it's almost the New Year, you still come to me, what is so important!"

Ouyang Liang said: "We are a member of the railway construction, the Chinese New Year is too luxurious for us, I now only have one thought, strive to build the railway we are responsible for, and strive to complete it as soon as possible." I came here now mainly to see the construction of Jiuzhou Heavy Industry's large shield machine. ”

That's what happened.

Not long ago, he personally went to Jiuzhou Heavy Industry, went deep into the production site, and watched the production and manufacturing of large shield machines, whether it was the "Pioneer" or the "Caiyun" very satisfied, and Zhu Yifeng basically reached an order intention.

However, before the formal contract was signed, he still wanted to see the work of these large shield machines with his own eyes.

Liang Zhijian said: "Old man, the construction volume of your line and tunnel is also very large." ”

Ouyang Liang said: "No, the length of the railway line is only two or three hundred kilometers, and there are more than 20 tunnels of length and shortness, but our longest tunnel is not more than ten kilometers, and there is no tunnel as complex and difficult as your Dagongshan Tunnel." ”

"Lao Liang, how is the construction of your Dagongshan Tunnel?"

Liang Zhijian laughed happily, "Now, I wake up with a smile in my dreams, since the arrival of this 'Pioneer', everything has become smooth, and now the tunneling length has reached four thousand meters, almost one-third." ”

"Ahh

Ouyang Liang was slightly surprised, he didn't expect the speed to be so fast, and asked in disbelief: "The construction of the Dagongshan Tunnel is a world-class problem, facing many fracture and fracture zones, many geothermal hot spring zones, and the geological conditions are very complicated. ”

Liang Zhijian said: "With the 'Pioneer', all the problems seem to have become easier, and it has successfully passed through many broken fault zones and many geothermal hot spring zones. ”

Jiuzhou Heavy Industry's large-scale shield machine is so good!

Ouyang Liang said a little impatiently: "Lao Liang, I want to take a look at its excavation, let's go, take me into the cave to have a look." ”

Liang Zhijian laughed, and then said: "Don't be in a hurry to see the construction of the Dagongshan Tunnel, I'll take you to the Xiaoling Tunnel to have a look." ”

"Oh. Ouyang Liang was slightly puzzled.

Liang Zhijian didn't care about 3721, pulled Ouyang Liang and got into the car, and the two came to the construction site of Xiaoling Tunnel.

Standing at the entrance of the tunnel, Liang Zhijian waved his hand and asked loudly, "How long will it take to get through?"

A technician wearing work clothes and a hard hat next to him said confidently: "In less than an hour, our Xiaoling Tunnel will be fully opened." ”

Hearing this, Ouyang Liang said in his heart, it turns out that there is a tunnel that is about to be opened, no wonder Lao Liang pulled me here.

He only guessed a little bit right, and the situation was not so simple. Liang Zhijian didn't explain anything, and said loudly: "Old man, let's go into the tunnel and take a look." ”

The total length of the tunnel is more than 1,000 meters, you can walk in, Liang Zhijian and Ouyang Liang walked in the front, followed by several people, and everyone walked into this tunnel.

With the help of the light, Ouyang Liang saw that the construction of this tunnel was not a traditional drilling and blasting method, and it was very obvious that a large shield machine was used.

It is also a 6-meter-diameter hard rock boring machine, which can be seen from the neat and knife-like traces of the tunnel wall, which is left by the hard rock boring machine.

After walking for hundreds of meters, the tunnel came to an end, and there was no longer a short distance ahead, apparently, this was a blind road, only about half of which was opened.

Ouyang Liang thought in his heart, didn't Lao Liang say that he was about to get through, why was it still very early, the depth was only a few hundred meters, not even a thousand meters.

Just as he was about to ask something, Ouyang Liang faintly heard a rumbling sound, and it seemed that there was some large construction machinery under construction on the opposite side.

Could it be......

This thought popped up in his mind, Ouyang Liang himself was startled, if it was really a construction mode of simultaneous excavation at both ends of the tunnel, it would be too exaggerated.

Such a tunnel of more than 1,000 meters long, said to be not long, but short is not short, both ends of the simultaneous excavation construction, the most likely problem is the problem of deviation, if not to catch up with the construction period, generally do not advocate the use of such a construction mode.

The rumbling sound is becoming more and more obvious, Ouyang Liang can be sure that there must be a large shield machine under construction on the opposite side, and looking at it like this, it is about to be opened, but I don't know how much deviation there will be.

After a few more minutes, the movement became louder and louder, and everyone could feel the slight vibration of the tunnel, and Liang Zhijian said loudly: "For safety, everyone step back a little more." ”

Everyone knew that the tunnel was about to be opened, and they all retreated at least ten meters to keep a safe distance, and then looked at the end of the tunnel with a little excitement.

Many people think in their hearts, it is unbelievable that it is about to be opened so soon, which has created a new record for the construction of railway tunnels in China.

The movement grew louder and louder, and at the end of the tunnel, some small rocks had begun to fall one after another, and soon, with a bang, many large rocks fell.

Finally, a behemoth revealed its hideous figure, the huge cutterhead was still rotating, and the remaining momentum was unabated, and the Xiaolingshan Tunnel was also opened at this moment!

……

Today's three watches, the second one is sent!
