How to view reconstruction?, The whole Beijing Tianjin Hebei region after a rare extremely heavy rainstorm | flood control | Beijing Tianjin Hebei region
On August 9, Beijing held a press conference to report the flood control and disaster relief of this rare extremely heavy rainstorm, and also announced the overall post disaster reconstruction plan: one year basic recovery, three years comprehensive improvement, long-term sustainable development, including the recovery of disaster areas, the overall improvement of disaster prevention and mitigation capabilities, and the overall improvement of infrastructure and basic public service security. What are the thoughts brought about by extreme heavy rainfall for post disaster reconstruction? This issue of News 1+1 focuses on the rare extremely heavy rainstorm in Beijing, Tianjin and Hebei. How to look at reconstruction after the disaster?
The geological hazard risk in the mountainous areas of Beijing is still relatively high
Liu Bin, Deputy Commander of the Beijing Flood Control and Drought Relief Command and Deputy Director of the Emergency Management Bureau: Currently, the main secondary disasters are geological disasters, such as landslides and collapses. At present, the mountainous areas of Beijing are still in the orange warning of geological and meteorological risks, which means that all scenic spots in the mountainous areas are closed, and the mountain channels need to be closed. The risk in the mountainous areas is still relatively high.
What work is still going on after the extremely heavy rainstorm?
Liu Bin, Deputy Commander of the Beijing Flood Control and Drought Relief Command and Deputy Director of the Emergency Management Bureau: In the current disaster area, the most important task is to focus on disaster relief, while also providing some assistance. We achieved the "Four Connections" yesterday, focusing on disaster relief work, including access to roads, electricity, water, and communication. Some of these four connections are temporary connections, such as power supply. In some villages, electricity is driven by temporary generators, while in others, communication is achieved through communication vehicles or even backpack style temporary communication. Water supply is also achieved through temporary water supply vehicles. These still require routine communication on a temporary basis, so disaster relief work needs to be further promoted. At the same time, we should also pay attention to epidemic prevention after disasters, so recently we have actively carried out the corresponding disinfection and sterilization work to prepare for epidemic prevention in advance. While providing disaster relief, we are also planning what to do for future post disaster reconstruction.
Future flood disaster response requires more basic support
Liu Bin, Deputy Commander of the Beijing Flood Control and Drought Relief Command and Deputy Director of the Emergency Management Bureau: In response to flood disasters, emergency response capabilities are limited, so first and foremost, there should be a good foundation. There are two aspects to the foundation. One is that there should be some improvement in flood control engineering, such as whether a certain flood detention reservoir can be built in the future in the gorge section, and whether we need to further improve the safety of downstream flood control embankments and the safety standards of soil flood control embankments. Furthermore, in the future reconstruction of disaster areas, it is worth considering how to effectively enhance the safety and resilience of mountainous villages. On the other hand, from an emergency perspective, when facing flood disasters, can we think more about the disaster? With the experience of this flood, I believe that both in terms of response and from the local people, there will be more personal thinking and improvement.
The flood control engineering system in the Haihe River Basin has played a huge role
L ü Juan, Director of the Flood Control, Drought Relief and Disaster Reduction Engineering Technology Research Center of the China Academy of Hydroelectric and Water Resources: A watershed is a flood control engineering system, and a river is divided into upstream, midstream, and downstream. Generally, reservoirs are built in the upper reaches of rivers, and the middle reaches can be used for diversion or as flood storage and detention areas. There are some water reducing channels in the lower reaches. The flood control engineering system of Haihe River has played a huge role this time. Without a flood control system, it would be far from the current state.
What role has been played by the activation of 8 national flood storage and detention zones?
L ü Juan, Director of the Flood Control, Drought Resistance and Disaster Reduction Engineering Technology Research Center of China Academy of Hydroelectric and Water Resources: ① As its name suggests, flood storage and detention areas are used for flood storage, especially for large floods. When floods come, the river cannot accommodate them. In order to avoid flooding some economic areas, residential areas, farmland, etc., flood storage and detention areas are opened in advance, waiting for the arrival of floods to divert them in. Then discharge downwards in an orderly and safe manner below the flood storage and detention area The 8 flood storage and detention zones played a very important role this time, with a total inflow of approximately 4 billion cubic meters. Installing a 100 million cubic meter reservoir is a large-scale water conservancy project. It can be imagined that a flood volume of 4 billion cubic meters will occur. If there is no flood storage and detention area, it will cause significant disasters if it pours into the Haihe River basin. So the eight flood storage and detention areas greatly reduced the losses in the Haihe River Basin this time.
