At about 9:00 p.m. on May 12, a 3-year-old boy fell into the sewer and was washed away in Huixi Village near the North Third Ring Road in Weiyang District, Xi'an City, Shaanxi Province.
May 15 is already the fourth day that the child lost contact. As of the 16th, the missing boy has not been found, and the rescue is still going on.
The whereabouts of the 3-year-old child has touched the hearts of countless people. At present, the official has invested more than 300 people in the search.
On the afternoon of the 15th, experts from various industries such as pipeline engineering design, water supply and drainage, and emergency rescue jointly conducted a comprehensive study and judgment on search and rescue.
The child's family is anxiously waiting, while more people are waiting in front of their mobile phones, hoping to find the child's news from the rescue frontline. Not giving up is the common wish of everyone.
This is not the first time that sewers have "eaten people".
10 years ago, on March 22, 2013, a heavy rain fell in the whole city of Changsha.
A senior student Yang Lijun, who was looking for a job in Changsha, accidentally fell into an uncovered sewer in the city, and was swept away by the rushing water, her whereabouts unknown.
It was not found until the morning of May 19 two months later. Unfortunately, Yang Lijun has passed away.
Today, the tragedy repeats itself, and the lessons are profound.
Both incidents were caused by problems with the manhole covers, which caused victims to fall into the sewers, raising safety concerns.
After the incident of "cannibalism" in Changsha's sewers, it attracted nationwide attention.
Many cities have learned lessons and installed anti-fall nets in the manholes. At present, it seems that this is the most effective way to prevent tragedies from happening.
This reminds many cities that problems that can be solved with a single network should not be delayed until a tragedy occurs and then repaired.
On the other hand, there are many difficulties in the rescue process, and the existing difficulties also remind us that it is imminent to improve the rescue efficiency.
The city's pipeline network is intricate. In the past few days, rescuers have almost turned over the surrounding sewers, but they still haven't found it.
The incident in Changsha was the same.
Every second counts for saving lives, and it is necessary to locate at the first time, so there is not much time spent in the process of searching.
The special nature of sewers also determines the need to use some special methods to add technology to the rescue, and think about solutions from a scientific point of view.
At the turn of spring and summer, many places will enter the rainy season and flood season one after another. Not only the south, but also the northern cities will have torrential rains, and the same should not be paralyzed.
How about the safety of the manhole? It needs to be checked quickly. If there is no anti-fall net installed, quickly install it, and if it is installed, check whether there is any leakage or damage.
In particular, some manholes that have not been included in the municipal pipeline network, the manholes in Xi'an this time are located on the village road, and the staff of the Weiyang District Emergency Management Bureau also admitted, "The village road is managed by the village itself, and there are imperfections. Unlike Municipal roads, facilities, and management are better." The problems in townships and rural areas and some urban-rural junctions may be more serious and need to be paid more attention.
