After waiting for a long time, I waited for a Chinese subtitle translated by a Russian machine into English. It was not bad after reading it, and I felt a lot of small details.

1. After the subway hit and hit, the little girl's father pulled the little girl out of the crowd, because she was not sure whether the little girl had hurt her bones or not, and then asked the little girl to move her hands→arms→...when it was critical These little things can save lives!

2. The little girl's mother's lover saw that the lights on the subway were still on, and realized that there was still electricity in the subway. If she got off the car and went into the water, she would probably be electrocuted. This idea saved several people with halo above their heads. The life of the protagonist!

3. The Leningrad subway accident is mentioned in the movie. I think this movie is based on the two subway accidents of Leningrad (St. Petersburg) in 1974 and 1995.

Brief introduction to the accident of Leningrad Metro Line 1:

On April 8, 1974, when excavating the off-line tunnel, an unfrozen area was excavated, causing the quicksand to protrude. The quicksand volume exceeded 40,000 cubic meters, and quicksand also occurred in the on-line tunnel. protrude. The tunnel was quickly submerged. In the process of 6 hours, the 2 tunnels were filled with loose sand from the working face to the working well (about 600m), and finally 2 stacks of 3m thick blocking walls were built at the forest station to be controlled. ACCIDENT. The accident caused the ground to subside, forming a 400m × 200m groove, with a maximum subsidence of 3.5m at the center of the quicksand protrusion. The buildings and buildings in the settlement area were greatly deformed, and some of them were destroyed. After the accident, liquid nitrogen was used for freezing, which was the first time in the world that liquid nitrogen was used for freezing. The tunnel restoration work was carried out directly in water, and the sand flow did not stop even at a temperature of -185°C. More than 8,000 t of liquid nitrogen was used, and the accident was finally successfully controlled. At that time, the 70m-long permafrost sealing body was completed.

On the night of December 3, 1995, a large amount of water poured into the lower tunnel, the upper tunnel sank sharply, and a disaster occurred. On December 4, 1995, the tunnel operation was terminated. On December 10, 1995, the emergency group meeting decided to flood the upper tunnel. On December 16, 1995, the off-line tunnel was also blocked for irrigation.

The Leningrad Pravda newspaper described the accident as follows: 20 years ago, the 3 t heavy steel waterproof gates that were pre-installed permanently closed the 500m long busy line of the St. Petersburg Metro from both ends. Thick concrete sealing wall. Roaring groundwater filled the closed section, causing massive subsidence of the overlying soil layer in the accident area, and damage to residential and factory buildings on the Integrated Technology Street and the Red October Plant area. Cars falling into pits, houses covered in cracks, groundwater billowing up. . .

Since then, the Metro Red Line has been split in two, and the long-term passenger flow of more than 500,000 people per day has to transfer to a free bus at Forest Station or Heroic Square Station to cross the closed subway section, and then go down to the subway line on the other side to continue. their itinerary.

Political factors leading to the accident:

In terms of route planning, an unreasonable route was adopted. The plan to cross the underground river was the most difficult to construct. It was selected because the project had a short construction period. If the project was completed before the big day, the tunnel digger could get a reward. At that time, the big day was the 25th Congress of the CPSU.

4. Beijing Metro Line 9 crosses Yuyuantan, and Line 13 crosses Kunyu River. I don’t know if this waterproof is reliable or not. There should be some subways in Beijing that are also under the river. Lines 9 and 13 are more familiar.
