It's a ground sensor!

What surprised Tang Fei even more was that these ground sensors didn't seem to have been installed by Tian Hao, but they should have been installed here by the cultural relics protection personnel next to them early.

Noticing Tang Fei's expression, Tian Hao explained: "Mr. Tang, this is a ground sensor, which is installed here by experts from the Municipal Bureau of Cultural Relics, which can be regarded as supervising the construction of our subway tunnel. ”

Tang Fei nodded a little to show understanding.

After all, this is the thousand-year-old Great Wall, which should not be destroyed, and its own shield machine should be able to withstand the test.

Tian Hao saw Zhou Xiping and greeted heartily: "Expert Zhou, you are here in person, how is it, has the ground subsided?"

Zhou Xiping frowned slightly, he had been here for a while, and he had just looked at the data of various sensors, which made him very puzzled.

So, he asked in a deep voice: "Mr. Tian, where is your shield machine, and has it approached the ancient city wall?"

Tian Hao was a little puzzled, and replied: "Our shield machine has been under construction, and it has not stopped at all, and now it is under the construction of the position where I am standing, no, it should have begun to pass through the city wall." ”

What the!

Have you already started to cross the city walls?

Zhou Xiping's face changed slightly, and then said loudly: "This is impossible, I just looked at the data of our sensors, and the ground has basically not settled." ”

After thinking about it, he said eagerly: "Mr. Tian, are you mistaken, has the shield machine stopped a long time ago?"

Tian Hao said with a smile: "It hasn't stopped, it hasn't stopped, this is the boss of Jiuzhou Industrial Group, the shield machine is produced and manufactured by them, Mr. Tang specially came over to see the situation of the shield machine passing through the ancient city wall, how could the shield machine stop!"

The shield machine did not stop, which is strange!

Tang Fei looked at Zhou Xiping, who was stunned, and said in a calm tone: "You are Expert Zhou, these ground sensors are all installed by you, can you take us to see the data of the sensors?"

After thinking about it, Zhou Xiping agreed: "Yes, everyone come with me." ”

Under the leadership of Zhou Xiping, everyone entered a simple board room not far from the side, in this room, there are instruments and equipment connected to the ground sensors, and there is also a computer, on the display screen of the computer, the data of the surface sensors is displayed, clearly.

Tang Fei took the initiative to take a look, mainly considering that the settlement of the ground should be very small, which must not be seen by the naked eye, and must be done with the help of instruments and equipment, and the data of various surface sensors can be seen, which is the most intuitive.

Everyone entered the room and looked at the data on the computer.

Zhou Xiping pointed to the computer and said: "At present, there is no settlement on the ground, Mr. Tian, you really didn't lie to me, the shield machine has reached the bottom of the city wall." ”

Seeing that Zhou Xiping still didn't believe it, Tian Hao smiled, took out his mobile phone and dialed a call in front of him, and said loudly: "Tang Gong, report your location, where the shield machine is." ”

"Tang Gong" is one of the technicians in charge of the construction of this subway tunnel, and he is now in charge of the construction of the shield machine, and he knows best where it will be.

Tang Gong's voice came from the phone, because of the special look at the hands-free, everyone could hear clearly, "Mr. Tian, hello, the shield machine has arrived under the ancient city wall, is crossing the ancient city wall, and there are about two hours or so to completely pass through." ”

Crossing the ancient city walls!

The TBM is digging under the city walls!

At this time, everyone heard it clearly, and Zhou Xiping no longer had the slightest suspicion, he looked at the computer screen, then at Tian Hao, and said in surprise: "Mr. Tian, it's unbelievable, the ground hasn't settled, it's unbelievable!"

Previously, he was strongly opposed to the construction of the subway, because he was worried that ancient buildings and places of interest would be affected by the construction of the subway, and even damaged.

For example, the construction of subway tunnels, in his cognition, will always cause a certain degree of land subsidence, and he has also carefully calculated that to make these ancient buildings immune from the impact of subway construction, the ground subsidence can not exceed 5 mm.

Such a small settlement, almost no shield machine can do, even if it is an imported shield machine, the degree of ground settlement is generally 8 mm, or even more than 10 mm.

Now, almost no land subsidence is occurring.

was originally strongly opposed to the construction of the subway, but at this moment, Zhou Xiping found that the opposition in his heart seemed to be much weaker.

As long as it does not affect the ancient buildings and historical places on the ground, he will not care how to carry out the construction of the subway tunnel. There is only one reason for the backlash, and that is the fear that these things will be affected.

Looking at these ground subsidence monitoring data, Tian Hao felt relieved, "Mr. Tang, your shield machine is so good, in the process of construction, the ground has almost no subsidence." ”

At this moment, Tang Fei's high heart was basically put down, but he still reminded: "The shield machine is still under construction, and I estimate that when it passes through the ancient city wall, a certain degree of ground subsidence will gradually occur, and it may be necessary to refer to the data within 24 hours." ”

Seeing Tang Fei say this, whether it was Tian Hao or Zhou Xiping, they became worried again.

Seeing that everyone's reaction was a little big, Tang Fei said easily: "However, you don't need to worry, the tunnel is currently being excavated, and the ground is basically not settled. ”

Tang Fei roughly estimated that the settlement within 24 hours would be at most 2 or 3 millimeters, and it would not reach the level of 5 millimeters at all.

Seeing this, everyone was a little worried, but immediately relaxed again. Tian Hao even jokingly said, "Mr. Tang, I was almost startled again, since the settlement will be very limited, then I will rest assured." ”

Zhou Xiping also said: "I was against the subway construction before, as long as the ground settlement does not exceed 5 mm after the shield machine passes through this ancient city wall, I will not object to the subway construction in the future." ”

Tian Hao was pleasantly surprised!

In the past, because of the opposition of cultural relics experts like Zhou Xiping, the subway line has been modified several times, so that the cost has risen, and there are no stations in some places where the station should have been set up, and the convenience of the subway has been greatly reduced.

Originally, after the construction of the subway, many citizens who could take the subway at their doorstep needed to walk a long distance to get to the nearest subway station.

It's good now.

As long as people like Zhou Xiping no longer oppose it, the subway lines built in the future can be freed to spare, and there is no need to blindly consider avoiding ancient buildings, places of interest and so on.

Even if the subway tunnels pass under the ground in their area, that is no problem. In this way, the future subway lines can fully consider the convenience of citizens.

"Mr. Tang, thank you, thank you so much!"

Tian Hao held Tang Fei's hand tightly, his eyes were full of gratitude. His shield machine has been recognized by customers, and Tang Fei is also proud in his heart.

"Mr. Tian, don't thank you, if you think our shield machine is better, when we carry out the construction of Line 2 and Line 3 in the future, we will order a few more units. ”

"Definitely, that's definitely. Tian Hao immediately agreed.

Everyone stayed here and did not leave until evening, when the EPB machine had passed under the ancient city walls and continued to move forward.

In order to express his gratitude, in the evening, Tian Hao prepared a sumptuous dinner, and ate this dinner at the best hotel in Dongyang City.

Zhou Xiping and the others did not leave, but continued to monitor the subsidence of the ground there. After the TBM passes through, there may be a certain degree of ground subsidence within 24 hours, and they need to confirm the inspection data to determine how much the ground will settle.

In the monitoring room composed of simple board rooms, the lights are bright, various instruments and meters are working, and the computer display screen displays the data transmitted back by each sensor in real time.

Zhou Xiping didn't dare to leave and stayed there all the time.

It wasn't until late at night that he squinted on the sofa and slept for a while, and when he was asleep, he was pushed awake, Xiao Xie said eagerly: "Expert Zhou, take a look, there are several changes in the data of ground sensors." ”

Suddenly, Zhou Xiping's sleepiness was gone.

He immediately bounced up from the sofa, quickly came to the computer, and stared at the data on the display, but after only looking at it for a while, the expression on his face gradually relaxed.

"Xiao Xie, don't make a fuss, it's just a slight ground subsidence, and the subsidence is only a little more than 1 millimeter, well, I'll go sleep for a while, and you guys will take turns to rest." ”

He is an expert, and he knows that after such a long time, it has only settled more than 1 millimeter, and it is estimated that even if the settlement occurs again, it will not be serious.

So, I slept peacefully on the sofa and didn't wake up until morning. After getting up, I looked at the data on the computer, and I was completely relieved that the most powerful point of ground subsidence was not yet 2 mm, and the distance was 5 mm, which was still far away.

When Tian Hao sent Tang Fei to the airport, he happily told Tang Fei that until now, the amount of land subsidence was only about 2 mm, which can be described as not moving at all.

"That's good, then I'll go back with confidence. Tang Fei said with a smile.

……

Two days later, Matsumoto returned to the vicinity of the ancient castle wall.

In the past two days, he has had a very relaxed life and has a good visit to Dongyang City. Because I am sure that it will definitely cause a large area of ground subsidence, this ancient city wall should have cracked, and it is good to go back after taking pictures.

He took the camera and quietly went to the ancient city wall, originally wanting to take pictures, but when he saw the ancient city wall that had not changed at all, his face changed.

…….

Today's three watches, the third watch is over, and I ask you for monthly ticket support!
