2022 Jinan Yellow River flood prevention plan was officially issued

Qilu.com · Lightning News July 21 News A few days ago, the General Office of the People's Government of Jinan City issued the "Flood Control Plan for the Yellow River in the Jinan City in 2022" (hereinafter referred to as the "Plan"). The "Plan" pointed out that when 22,000 cubic meters per second of floods occurred at the Yellow River Garden port station, the flood dividing through Dongping Lake and controlling the leakage flow of the lower part of Aishan Station was not more than 10,000 cubic meters per second. In seconds, make sure that the embankment is not decided; when you encounter super -standard floods, do your best to reduce the impact of the flood.

In the Jinan section of the Yellow River, the Ginger Gulf in Dong'e Town, Pingyin County, and the Laosangjiadu of Renfeng Town, Renfeng Town, Jiyang District. The right bank of the river above the north of Huaiyin District is Changping Beach District, and the river width is generally 2-7 kilometers. At the end of 2020, in accordance with the standard of 11,000 cubic meters per second of the Yellow River, 33.881 kilometers were built, including 4.635 kilometers of Pingyin section, 22.96 kilometers in Changqing section, and 6.286 kilometers in the Huaiyin section. The following is a curved narrow river channel restricted by the project. The width of the river is generally 0.5-2 kilometers. The narrowest part is the No. 17 dam in Caojia Circle Insurance of Huaiyin District, and the banks of the banks on both sides of the bank are 444 meters. The general characteristic of the Jinan River section is the width and narrow on the river, and the current flat slot flow is about 4800 cubic meters per second. The tributaries that come in in the Jinan River section are from top to bottom. kilometer.

The "Plan" pointed out that the flood prevention situation is affected by global climate change and human activities. The climate situation in my country is becoming more and more complex, and the sudden, abnormalities, and uncertainty of water disasters are more prominent. Extreme incidents such as super typhoons have increased significantly. According to the forecast of the meteorological department, in the summer of 2022, the dry flow of the Yellow River Basin and the tributary Weihe, Fenhe, Qinhe, Yiluo River and other rainfalls were 3-50 %, and large floods may occur. For example, a large flood occurred in the upstream, and the flood of Dongping Lake is used. The river section of the Jinan City will meet or approach the defense standard.

In view of the unfavorable situation of the "second -level suspension" in Jinan City, some river sections are not conducive to the continuous development of the river. After the test of the flood, some phenomenon of the pads of the diseased danger have not been implemented, and some of the Yellow River projects affected by the middle and lower reaches of the Yellow River in the middle and lower reaches of the Yellow River in 2021 have not been fully recovered.

The "Plan" pointed out the analysis of the risk of floods. When the flow of more than 15,000 cubic meters per second in the garden mouth station, the corresponding flow of the corresponding flow of the corresponding flow of 10,000 cubic meters per second, the Yellow River Beach District will be all beaches, and the drowning area will reach 572,300 mu. Among them, the arable land was 356,300 mu, and economic losses were about 8.873 billion yuan. The city's 33,700 people need to move out. Among them, only 32,400 people need to be relocated to the Yellow River Beach District of Changqing District, and the task of security and security is arduous.

Among them, the key areas of flood prevention include: Huaiyin North shops to Lixing Huojiahu River, narrow and curved, and the river width is generally about 1 kilometer. It is one of the famous narrow river sections in the lower reaches of the Yellow River. The ground is more than 10 meters high, which is a typical "second -level suspension" river section, and the flood prevention tasks are very difficult.

From the Liujiayuan insurance workers in Zhangqiu District to the lower boundary section, the new and old kinetic energy conversion start area Xinjia to Jijia, Zhou Meng to Daliu store dyke section is prone to dangerous situations such as flooding.

The newly repaired damage has not been tested by floods, and some dangerous workers, controlling the roots of the dams of the dam, are inadequate, and are prone to major dangerous conditions such as pier and dams.

In the event of the flood, there is a danger of rolling river between Changqing Gu Xiaozhuang and Taoyuan Control Project.

When the traffic of the Piankou Station exceeds 5,000 cubic meters per second, the flood is poured into the Lashan flood ditch along the Yufu River. When the flood occurs, the starting point of the Yellow River embankment may still occur at the junction of the project of the 220 National Highway and Songzhuang Gate.

The 11 citations on the yellow embankment were mostly built in the 1970s and were identified by the gates. 9 of which were "three categories" gates and 2 were "two types" gates.

When there are many residential population in the Yellow River Beach, when the flow of Aishan Station reaches 10,000 cubic meters per second, 33,700 people need to move temporarily, and the task of relocation is heavy.

The construction of a bridge built by the river in the river can only safely pass the flood of 6,000 cubic meters per second, which can be safely risked by the flooding of flooding.
