The reality is far more severe than people expected.

This subway passage is a very important section of Fuzhou Metro Line 1. At present, 70% of the progress of the construction of Line 1 has been carried out, and only the section from the Convention and Exhibition Center to the Garden Villa Area remains.

The occurrence of water seepage at this time is definitely a fatal mistake for the entire project!

Why?

Tunnel leakage is not only to empty the seepage, plug the first can be, but also more than 10 meters below the water seepage, which will cause serious dampness in the cave. Thus affecting the service life of the mechanical equipment in the tunnel, thereby greatly increasing the maintenance workload in the tunnel.

In a mountainous area like Japan, it is not uncommon for tunnels to become flooded. According to statistics, the maintenance cost of these leaking tunnels is on average more than 20 times higher than that of normal tunnels!

However, if it is said that the water seepage alone increases the maintenance cost, it is actually good for the Fuzhou municipal government.

The geographical location of Fuzhou is similar to that of Tiancheng, both of which are located in northern China, and the lowest temperature in winter can exceed minus 30 degrees. In such cold areas, leaks in underground tunnels can cause severe freeze swelling, which can damage the lining and drainage prevention measures. The current location of Line 1 is still below the artificial lake, and if such a situation occurs, the impact on the entire Line 1 will be too great;

Water leakage and freezing are likely to invade the limit and endanger the safety of the tram. If there is leakage in the electric traction section, it will also affect the power wiring, causing insulation failure, short circuit, tripping, discharge and other accidents, thus threatening the personal safety of the tram and passengers.

However, there are more serious things for this subway line.

That's ...... The stratum in this section is the bottom layer of pebbles, and above the stratum, there is an artificial lake with an area of more than 2,000 square meters!

If the ** continues to expand...... Eventually, the lake will be flooded, and more than 8,000 cubic meters of lake water in the lake will ruthlessly engulf the entire subway line!

If that happens, it's a big deal.

This is not just a matter of words, the water seepage in the underground tunnels is already quite serious.

The situation in front of the Fuzhou municipal government is that the entire Metro Line 1 may face a complete shutdown. You know, the subway is not like a road, there is a mountain bag here to bypass, and there is a nail household here to build a fork in the road.

This is not to mention how much more work is needed to redeploy the project, how many social forces need to be mobilized to redesign the route, how many practical troubles to solve, and how many social contradictions need to be coordinated. Even if the tunnel that has been dug is filled in at the moment, the loss will be great.

The third company of China Railway 13th Bureau is also facing the catastrophe of extinction.

Now the use of digging the underground tunnel is not a shovel or pickaxe, but a shield tunnel excavator imported from Switzerland worth more than 40 million yuan.

What does this EPB look like?

The large metro shield machine is actually like a huge cylindrical drill bit, with a diameter of more than nine meters and a total length of more than 60 meters.

This tunnel boring machine excavates using the shield method, which integrates excavation, support and slag removal. By combining the functions of measurement, automatic correction, and tunnel laying, it is possible to realize the one-time molding of the tunnel.

In other words, it is like a huge drill bit, which can be used to fill the excavated part with a layer of cement at the same time, so as to directly form the tunnel.

Tunnel excavation construction with this thing can be started with the highest degree of automation, greatly reducing manpower and material resources, and the construction speed is particularly fast and not affected by the climate.

However, there is also a fatal flaw in playing Ying'er, that is...... You can only advance, not retreat!

Unless the work is completed, it can be dismantled and lifted out of the terminal exit by a large crane.

Now, affected by the collapse of knives, pebble soil and leakage, this "big drill bit" worth more than 40 million yuan has completely rested in the tunnel. In the tunnel where there is no village in front of the village and no shop behind, if you are soaked in water...... Whether it can be repaired or not, it is difficult to say.

More than 40 million pieces of equipment were scrapped, and Zhao Fangshan was a director..... Obviously, it can't be resisted.

Seeing the heads of several construction engineering companies staring at each other with big eyes, and without speaking or expressing their position, Secretary Han was furious.

He unzipped the black jacket, pinched it on his waist with one hand, and tapped the people with the other, and scolded: "When you came to the city to get the project before, you were all confident, and the clapping of your chests almost said that you could go to the moon to do the project! Why are you not angry now? are you dumb?"

A thin monkey-like man scratched his ears and said, "Secretary Han, this is ...... He's in a different situation. You said that on this cold day, the permafrost is estimated to be five or six meters, how can you let us quickly dig up the ground to drain the seepage and rescue the machine?"

"That's right, Secretary Han, we can actually dig, but in the current situation, if we dig into the ground for seventeen meters...... It is estimated that it will take ten days and eight days at the earliest. By that time...... Ahem, ahem, ahem, a

Seeing that someone took the lead, everyone immediately complained.

"Enough!"

Feeling like a swarm of flies around his ears, Han Zhaojun was anxious, "A bunch of useless things, if you can't do it, get out, don't embarrass me here!"

The crowd took a few steps back and said no more.

For a time, the scene was at an impasse. The scene was embarrassing for a while......

By this time, Li Fanyu, who was standing in the crowd, had already completely understood this matter. He looked at the frozen surface of the lake, which had formed a thick layer of ice, and pursed his lips, distracted.

"Since it's all leaking, why don't you just empty the lake?" he muttered, probably thinking too much.

"Who's talking? Someone is suggesting to stand up and say! What is muttering down there?"

Secretary Han, who was angry, heard someone stealing, and immediately roared angrily.

The people around Li Fanyu were like small fish scalded by boiling water, and they "brushed" and dodged away, revealing him.

Nest!?

Seeing that the old man in the practice uniform just now even pointed at himself with his finger, Li Fanyu grinned - Damn! Who are these people!?

Li Fanyu didn't know that Secretary Han's temper was notoriously irritable in Fuzhou.

Once, at a party affairs meeting, this secretary directly slapped the table in front of reporters and scolded his subordinates: "I think the biggest difficulty in this matter is you! What do you want you to do if you have no difficulty? If you can do it, you just give me a job, and if you can't do it, quickly resign from my job and go home and drill the crotch of the old lady's pants! Although we have a rich name in Fuzhou, we are not rich enough to raise so many useless officials!"

When inspecting the construction site, he directly grabbed the collar of the person in charge of the project, held the unqualified concrete in his hand, and shouted: "This is your project? Get out of here, you don't need to do this project! Don't find someone to make it clear for you, the one who can get along with you is definitely not a good person." You remember, from the city to the province, if anyone dares to say a word for you, I will report him directly to the procuratorate!"

Therefore, in the one-third of an acre of land in Fuzhou, everyone knows that when Secretary Han is angry, he can't be provoked.

The people around looked at Li Fanyu and gloated, and said in their hearts: "You look good today."

Han Zhaojun was stunned when he saw Li Fanyu in the crowd.

Then he took a deep breath and strode over.

Just when everyone thought that this young man who was talking nonsense was going to be scolded by Secretary Han for being a bloody dog.

"Dong Li, I'm ashamed to let you be a distinguished guest...... Look at the joke. ”

Han Zhaojun stood still in front of Li Fanyu, who was "trembling", and smiled bitterly. 10
