廣西、四川暴雨來襲 吹爆玻璃門 馬路變汪洋 大樹連根拔起

Hello everyone, welcome to watch China program, I'm Meilin. Recently, there has been a heavy downpour in Yulin, Guangxi, which has caused severe flood disasters in Yulin. Due to the strong rain, and the long duration of the rain, the city's drainage system is unbearable. Many roads are severely flooded and traffic is congested. This is the scene on June 9 on Yulin Street. The water has flooded the road, and pedestrians are unable to walk. Some netizens said, the flood didn't stop a few days ago, and today it's raining again in Yulin. In less than a month, Yulin has experienced three heavy rains. Each heavy rain brings challenges to the city. The rainwater continues to accumulate on the street, forming a deep drainage area, which makes it very difficult for pedestrians and vehicles to pass. The rainwater not only affects residents' daily travel, but also causes some houses and shops in low-lying areas to be flooded. Some houses and farms have been damaged, and the loss of people's property has also been further aggravated. A few days ago, there was a heavy rain in Wuzhou, Guangxi. A large amount of rainwater caused the city's streets and houses to be flooded. The water level soared. Wuzhou City Government staff said, the local part of the Zhongxiao River has already seen a super-emergency flood. At present, there are no reports of casualties. The loss of property is being further analyzed. However, when reporters asked the Wuzhou Emergency Management Bureau about casualties and disaster relief progress, a female staff member said in a loud voice that the disaster situation could not be informed and refused. In the face of natural disasters, the most suffering thing is the people. A video posted by a resident of Guangxi Fangcheng said, When I woke up, I found the roadside collapsed, my car fell into the water pit, and my house was flooded. Many other areas in Guangxi have also been hit by heavy rain. The streets seem to have turned into a waterway. The mudslide area is also serious. Some residents have to shoot water and take the risk of crossing the chicken water area. Many car owners did not have time to move their cars. As a result, the car was flooded. The car was full of mud and dirt, and the damage was severe. In addition, the farmland was not spared. Part of the crops were submerged in the flood. Farmers are hard-working and suffering losses. In addition, not only in Guangxi, but also in many places in Sichuan, heavy rain and strong winds have also come recently. This is a picture taken at a hotel in Yibin, Sichuan. There was a heavy rainstorm, and the glass door was directly blown off. This is Panzhihua, Sichuan. The mainland media reported that it was the first time in decades that it rained so hard. The storm came, and the city streets could not tell whether it was a river or a road. The water level rose rapidly, and the water flowed into the village. For cars driving at night, it was even more of a test. The city's traffic tunnel also became a severe disaster area. The tunnel, which was originally busy, suddenly became an underground river. A netizen posted a video saying that he almost couldn't go home. It can be seen everywhere that the trees and road signs On the way, he was nervous. The water on the road has flooded the position of the car door. However, this is just the tip of the iceberg of the storm. As we can see from the video, a big tree in the community collapsed on the roadside It can be seen that the wind is very strong. In some areas, all the solar panels on the roof were blown off, and even the steel tiles were blown down. After the storm, there was a mess on the street. A large amount of mud and debris floated into the alley with the flood. The car was submerged in it, and the mud was all over the body of the car. Some cars were even washed into the ditch by the roadside. The bottom of the car was completely submerged in the mud, and could not be moved. In addition to the damage to the car, a large amount of debris was scattered on the street. Broken branches, broken trash cans, scattered building materials, and countless abandoned items scattered around in the flood. This is a video recorded at 2 a.m. At that time, the rain poured down. The rain was like a flood in the community. The house on the first floor was submerged. The young man rushed through the soaked floor and rushed out of the house in a hurry. Because his car was still parked in the garage of the community. The garage had long been flooded. After leaving the house, he found that the road had become a waterway. On the way, he had to avoid the deep water area and not let himself be washed away by the water. Finally, he arrived at the parking lot. He was very worried. Fortunately, the car could still drive out of the parking lot without much loss. And the factory's factory was not so lucky. Rain water poured in from the door, the gap behind the window, and the drain pipe. The bottom of the machine equipment had begun to soak in the water. Some of the low-end equipment had even been completely submerged. The goods and raw materials in the warehouse were also soaked in the water. The factory owner said that a heavy rain brought a great loss. After the heavy rain, the problem of urban inundation has attracted widespread attention in recent years. Some analysts believe that in addition to natural disasters, there is also the impact of urban planning and transitional urbanization. On the one hand, many urban planning excesses are focused on economic development and land use, neglecting the protection of the natural environment and the improvement of urban disaster prevention capabilities. Overcrowding, ground hardening and unreasonable architectural layout make it difficult for urban rainwater to be discharged. Once the rainstorm comes, the road becomes a river, the parking lot becomes a lake, and the inner city is difficult to avoid. The next is that some of the long-term problems in urban planning and construction management have not been fundamentally solved and are also the causes of flood disasters. For example, the water drainage and drainage channels are occupied in urban development, resulting in insufficient effective discharge of floodwater. In addition, the excessive drainage of groundwater also leads to the collapse of the ground and the shrinkage of the ecological system, which has exacerbated the impact of flood disasters. For example, in 2021, the Henan-Zhengzhou storm disaster showed that although underground facilities can absorb water, if the design is not proper, it may lead to a more serious disaster. The underground space between Zhengzhou River and the building is interconnected and forms a large-scale interconnection. But once the flood enters the underground facilities, it will lead to a disastrous situation. In addition, China's urbanization process is too fast, the population density is too high, and the land resources are limited. This makes urban construction more centralized and highly densified. A large number of skyscrapers, hard-to-reach roads, and a lack of green belt urban design have increased the risk of urban inundation. Urban inundation not only causes traffic congestion and property loss, but also threatens the safety of residents. In order to solve the frequent flood disasters, the Chinese Communist Party has introduced a new urban planning concept, that is, a sponge city. However, although the concept of a sponge city has been widely promoted in China, the actual effect is not very popular. The sponge city is designed to be a sponge that can absorb, store, and flow rainwater It is designed to reduce the occurrence of urban floods, improve the problem of urban inundation and water quality, and improve the ecological quality of the city. This concept originates from Western countries, such as Germany and the Netherlands. The purpose is to solve the problem of drainage in the process of urbanization, and promote sustainable development of the city. The design of the sponge city includes the use of permeable cloth materials, the construction of green roofs and rainwater gardens, the preservation of wetlands and river banks, and other measures to reduce rainwater flow to the maximum extent, increase the permeability of the surface, achieve the effect of natural penetration and purification. This design concept aims to reduce urban flood risk, improve the ecological environment of the city, and improve the sustainability and sustainability In some Chinese cities, especially in places like Henan, Zhengzhou, and Hebei, sponge cities have not been able to effectively prevent floods in recent years As a result, when the concept of a sponge city is promoted, investment is insufficient, construction progress is slow, so that the construction area of ​​a sponge city is far from meeting expectations, causing its functions to fail. In addition, the concept of a sponge city is more suitable for cities with low population density and rich land resources. However, in China, many cities have a dense population and limited land resources, so the implementation of sponge cities faces many difficulties, especially for super-large cities, whose scale and effect are more difficult to achieve. The construction of sponge cities requires high-level technical support and scientific management, including the construction and management the collection of rainwater and the improvement of the utility system, etc. However, in many places, there are shortcomings in the level of technology and management, which leads to poor construction effects in sponge cities. China's climate and geological conditions are complex and variable, and the design of sponge cities may not adapt to the actual situation In some places, there may be too much groundwater, and the soil is not suitable for irrigation, which limits the implementation of sponge cities. Thank you for watching.
