Flood outbreak in Qiantang River basin?
According to last night's forecast, Lanxi in the upper reaches of Qiantang River ushered in the flood peak of Lanjiang River at about 2 am today, with a water level of 32.20 meters. This is the second largest flood in the local area after the founding of the People's Republic of China, and it flows eastward after flowing into Qiantang River.
Today happens to be the third day of the sixth lunar month, and the Qiantang River ushered in an astronomical tide. The water level of Qiantang River Zhakou Station (white pagoda park) is likely to exceed the historical highest water level by 8.02m during the flood from 3: 00 to 6: 00 1997 today.
Why is the water level so high?
On average, it takes 24 minutes for a West Lake to pour into Quzhou.
The south source of Qiantang River is in Ma Jinxi, Quzhou, winding to Lanxi City, and it is called Lanjiang after being merged into Jinhua River. Xin 'anjiang and Lanjiang meet in Meicheng, jiande city, and then flow northeast. The section that goes down to Dongjiangzui at the mouth of Puyang River is called Fuchun River, followed by the well-known Qiantang River section.
The high water level is mainly affected by the heavy precipitation in Jinhua and Quzhou. Yesterday 19, the water level of the Lanjiang River was 32.03m, exceeding the guaranteed water level1.03m.. The guaranteed water level is the water level at which the dike project can ensure its own safe operation. Lanxi started flood control level I emergency response.
The situation in Quzhou is also not optimistic. According to local media estimates, according to the city's rainfall of 99 mm, it is equivalent to the amount of water poured into 62 West Lakes within 24 hours, with an average of one in 24 minutes.
The high water level of Lanjiang River is most affected by the neighboring jiande city, and the Jiande Lanjiang section has exceeded the guaranteed water level. Tong Dinggan, secretary of Jiande Municipal Party Committee, visited the flooded village. Many elders said that this was the worst flood since 1955. It is understood that nearly 3,000 people in Dayangji Town have been transferred to the nearest disaster avoidance point.
Tonglu County is mainly influenced by Fuchunjiang Town and Tongjun Street, and some low-lying houses and basements along the street are flooded.
Fuyang water level is 8.82 meters, which is very close to the guaranteed water level of 9 meters, mainly ensuring Jiang Xinzhou such as Dongzhou Island and Xinsha Island. Taking Dongzhou Island as an example, Shuangpu Town in Xihu District is also called Chang 'ansha, and Fuyang and Xihu District all assign special personnel to take charge of flood control, carry out dragnet investigation on low-lying and waterlogged areas along the river, and organize the transfer of personnel and important substances in dangerous areas.
The situation in Xiaoshan and Dajiangdong is relatively stable. Yesterday, the Municipal Defense Index sent an expert group to dock five blocks in Jiande, Tonglu, Fuyang, Xiaoshan and Dajiangdong to prepare for the possible highest water level in history.
The flood discharge peak under Qiantang River and the lunar spring tide meet in the main city!
At 2: 30 this morning, Lou, deputy director of the Hangzhou Urban Management Committee and deputy director of the Municipal Anti-finger Office, said: "At present, the strongest heavy precipitation since entering Mei on June 9 this year is very large. Due to Quzhou, Jinhua and other areas and the central and western Zhejiang, after the rainstorm, including our Hangzhou, all the water was concentrated in Qiantang River. Especially in the area from Jiande to Tonglu at the junction of Lanjiang and Xin 'anjiang in the upper reaches of Qiantang River, the pressure is very high and the water level is very high.
At about 4 am, the flood peak and spring tide under Qiantang River will meet in the main city section, and the flood control situation in the main city is severe, and there may be flood backward flow. Qiantang River North Shore Scenic Area, Xihu District, Shangcheng District, Jianggan District and Xiasha Road along the river; Roads on both sides of Qiantang River, Dajiangdong and Xiaoshan District were once controlled.
In particular, Zhijiang Road on the north bank of Qiantang River: the section from Zhipu Road to Qianjiang No.4 Bridge is the key protected area.
Explain the connotation of insurance with hot events, and property insurance will interpret the risk protection behind news events from a new perspective.
In response to the "Qiantang River Basin Flood" outbreak, industry experts told the property insurance channel that the risk of flood outbreak is extremely high, especially when driving in the rain, and special attention should be paid to the following matters:
Keep a good view: In addition to driving carefully in rainy days, turn on the wiper in time, and turn on the low beam and anti-fog lights when the weather is dim. If the front windshield is frosted, turn on the cold air and blow it on the front windshield; If there is frost on the rear windshield, turn on the rear windshield heater to eliminate the frost as soon as possible, so as not to see the vehicles behind you clearly.
2. Prevent the wheels from slipping: When driving in the rain, "lubricant" is formed between the rain on the road surface and the tires, which makes the braking performance of the car worse and easy to slip. Therefore, the driver should hold the steering wheel with both hands in balance, keep driving in a straight line at a low speed, and when turning, he should step on the brakes to slow down to prevent the vehicle from slipping due to tire locking.
3. Drive slowly in low gear: experienced drivers know that no matter how narrow the road is and how good the road surface is, try to drive in second or third gear in rainy days, and the speed should not exceed 30 km/h or 40 km/h, always pay attention to the distance between the front and rear cars and their own vehicles, and make psychological preparations for various emergency measures in advance. If you need to stop, try to slow down 100 meters in advance and brake lightly, so that the cars behind you have enough emergency preparation time.
4. Prevent the car from sinking into the water: When the car passes through the water-logged road surface or under the overpass, deep tunnel and other water-logged roads, stop to check the water-logged depth first. The water depth exceeds the exhaust pipe, which is easy to cause the car to stall; The water depth exceeds the bumper and it is easy to get into the water. Do not cross ditches and puddles at high speed. This will cause splash, increase the actual wading depth, and easily lead to engine water intake.
5. Never start the vehicle again after the engine is turned off: Once the engine is turned off with water, never start the vehicle again. You should park your car and wait for it to be towed away. The most fearful thing for a car when driving is to suck water into the combustion chamber, because once water enters the combustion chamber, it will cause fatal injury to the overhead valve or overhead piston connecting rod when the engine is working because of the incompressibility of water; At this time, the loss is very serious, and engine overhaul is inevitable.
6. Pay attention to following the car: especially the big car should not follow too close. First, it will block the line of sight; Second, the stagnant water car that the big car can pass may not pass, and the big car is easy to splash water waves, which makes the car suffer.
7. Pay attention to pedestrians: Because pedestrians hold umbrellas in the rain and cyclists wear ponchos, their vision, hearing and reaction are limited, and sometimes they turn sharply to cross the road, often panicking and slipping when vehicles approach, which makes drivers unprepared. In this case, drivers should slow down, avoid patiently, choose a safe place to park when necessary, and must not compete with pedestrians and bicycles.
8. Turn on the lights in time: When the line of sight is extremely low during the rainstorm, turn on the headlights, position lights and rear position lights, and drive the vehicle off the road or park it in a safe place.
