[Explanation] At 6 o'clock on July 24, after the Natural Disaster Engineering Emergency Rescue Center of the Ministry of Emergency Management of China (China Aneng), the Huaihe Crossing Tunnel in the Beijing-Guangzhou Section of Zhengzhou achieved two-way penetration and bottomed out and is undergoing comprehensive testing. .

  [Explanation] A few days ago, a continuous heavy rainfall made Zhengzhou a "Zeguo", and the urban area was seriously flooded, which caused serious water accumulation in the tunnels of the Beijing-Guangzhou Expressway, the "main artery" of Zhengzhou.

According to public reports, there are 2 kilometers of flat roads and 4.3 kilometers of tunnels south of Jianshe Road on the Jingguang Expressway.

  [Explanation] The official "Henan Release" on the 23rd quoted Xinhua News Agency as saying that the Zhengzhou Jingguang Road Tunnel, which was submerged in the heavy rain, has attracted much attention. Hundreds of vehicles are piled up at the south exit of the tunnel. The rescue team is currently working. The tunnel was drained, but there is still a large amount of water in the tunnel. It has been confirmed that some people have been killed, and the specific number of people is still being verified.

  [Explanation] In this rush to assist Zhengzhou, China Aneng dispatched 22 "Dragon Suction", of which 18 "Dragon Suction" were distributed in tunnels and other places on the Beijing-Guangzhou section for flood drainage operations.

  [Explanation] According to public information, the "Dragon Suction", known as the "artifact" of flood fighting, is an emergency drainage rescue vehicle with a maximum pumping capacity of 3000 cubic meters per hour.

As an important equipment for urban drainage, the "Dragon Suction" has a large working range, large flow, and flexible mobility, which can eliminate floods in special areas in a short period of time.

  [Explanation] After confirming the safety, the reporter followed the staff into the exit tunnel of Zhongyuan Road of Jingguang Road Tunnel at noon on the 23rd. The drainage machinery and equipment roared to my ears, and the operator was in the water to ensure the safe operation of "Dragon Water".

  Here I am mainly responsible for alerting, the second is to clean up the debris, and the third is responsible for the operation of the pump, to maintain its normal operation, and to eliminate the danger in time.

  [Explanation] The latest statistics show that after continuous uninterrupted operations, as of the morning of the 24th, China Aneng has pumped more than 3.69 million cubic meters of drainage from various mission points in Zhengzhou this time, and the water level of the Jingguang Road tunnel has dropped significantly.

  We have equipped 18 "Dragons Absorbing Water" in this position, all with full horsepower, (the accumulation of water in the tunnel drops) is too obvious, basically the tunnel is open here, and we can see each other.

  [Explanation] The reporter found that Zhengzhou still has many tunnels at the intersection of Longhai Road and Malu, Jinshui West Road Tunnel, Huanghe Road Tunnel and other tunnels that still have serious water accumulation, and rescue forces from all parties are also "full fire" for flood drainage operations.
