After 20 years of Western Insurance Datang, why is the bid for 20 years? Why is this related to the future of Hangzhou?

On the morning of August 31st, the national key water conservancy project Dongzhengxi flood prevention and follow -up Western insurance Datang reinforcement project was officially started in Yuhang District, Hangzhou.

Following the reinforcement of risks 20 years ago, the Western Insurance Datang again raised the bidding -this project planned the flood control standard of Western Insurance Datang from 100 years of the original designed to 200 years.

As an important flood control embankment for Gongwei Hangzhou, the specimen of Western Insurance Datang is the meaning of the title. But under the context of the high -quality development of Hangzhou and Zhejiang at present, the meaning behind this project seems to be far more than flood control, but also about the future of Hangzhou cities.

Concern

Why do you want to make bids from "100 Years" to "One Encounter in 200 Years"?

As soon as the flood season, Dongyingxi in the north of Hangzhou City was "stressful." Because of its source in Tianmu Mountain, one of the center of Zhejiang.

On the right bank of Dongyingxi, the embankment from the Nanhu flood gate in Yuhang, Hangzhou to the gate of Deqing, is the Western Insurance Great Pond. Datang is 44.6 kilometers in length, including 38.7 kilometers in Hangzhou section and 5.9 kilometers in the Deqing section.

In the flood prevention situation in Zhejiang, the safety of Western Insurance Great Pond is also the top priority.

Xu Weilin, a member of the Party Committee of the Forestry Water Bureau of Yuhang District, Hangzhou City, said: "Every time in the flood season, the heavy rain in the mountainous area of ​​more than 1,500 square kilometers of Tianmu Mountain and the remaining pulses will be remitted into Dongzhengxi. huge loss."

This is not a joke.

According to the record, a typhoon in September 1963 made a small gap appear in a side wall of the South Lake flood gate. Cm, the road can be supported on the road.

Therefore, whether the Western Insurance Datang is stable, it is directly related to the urban safety in the eastern plains of Hangjia Lake and the urban area north of the Qiantang River in Hangzhou, as well as about 15 million people living here.

Due to the importance of the Western Insurance Great Pond, it has been "patching" from the Eastern Han dynasties. After the founding of the People's Republic of China, it has also carried out many heights and reinforcements on the Western Insurance Pond.

The Western Insurance Datang we see now is the reinforcement after 1995 to 2001. The standard of flood control is 100 years of encounter, and it has formed a relatively complete flood control system with the upstream and downstream reservoirs. This time, it directly raised the standard to a 200 -year encounter.

The so -called "100 -year encounter" is a standard term for flood control, and it is also a probability problem. To put it simply, the probability of the "100 -year encounter" flood occurs at 1%, and it may occur once in 100 years, while the probability of "200 years of encounter" is 0.5%. The improvement of standards means that the dyke body is wide, the entire line of anti -seepage, and solid -based stability should be upgraded in accordance with the new standards.

As for the improvement of the standard, one is because of the rapid development of Hangzhou in recent years -according to relevant national provisions, the number of non -agricultural population in Hangzhou's main urban area has reached 200 years of flood control.

The second is related to the urban development layout of Hangzhou. In recent years, as Hangzhou has deployed important protection objects such as the Western Science and Technology Corridor, Future Science and Technology City, Yuncheng, and Zhijiang Laboratory in the western area, the economic elements have gathered high.

The relevant person in charge of the Hangzhou Forestry Water Resources Bureau said: "It is urgent to increase the flood prevention standards from Western Insurance from 100 years to 200 years." It is imminent. "

Related development

Run the foundation for Hangzhou City New Center

On the first day of August, Yu Hang held the sixth session of the fifteen session of the district committee (expanded) meeting, and for the first time, it proposed the construction of a new center of Hangzhou City.

On the last day of August, the Yuhang West Insurance Datang's standard reinforcement project was officially started.

This seems to be a coincidence, but it is more like an echo.

"In a sense, the reinforcement project of Western Insurance Datang's standard is a foundation for Yuhang to build a new Hangzhou City Center." A staff member of the Yuhang District Government commented.

Why do you evaluate this? From one example, you can "see the whole leopard".

The Yuhang Shangnanhu Block has built the river laboratory and lakeside laboratory. The science and technology and economic elements have been highly gathering. However, at present, the block is threatened by floods, and the internal waterlogging is not excreted.

The reinforcement project of the Western Insurance Great Pond at the beginning is not just to increase the Great Pond of Western Insurance, but also includes high reinforcement to the Zhongqiao Pond and the east of Nanhu, and the new Nanhu hub.

After the reinforcement of the bidding, it can build a high -standard water safety defense system for the Shangnan Lake block, so as to better help the innovation sources of the Yuhang District and the entire Hangzhou City West Science and Technology Corridor.

Not only science and technology, but also the improvement of infrastructure along the entire Dongyingxi.

After the adjustment of the administrative division, the public infrastructure is its weak item. The Western Insurance Datang's standard reinforcement project is not a single water conservancy project, but a comprehensive ecological engineering.

At present, the construction plan of the "Eighteen Scenery of Western Insurance Great Ponds" has been screaming. Ge Xufeng, general manager of Hangzhou Yuhang Forestry Water Conservancy Investment Co., Ltd., believes that on the basis of satisfying the basic functions of flood control, we must deeply tap the humanistic style of Dongyingxi in history, integrate diversified functions such as landscape, leisure, sports, culture, and tourism. "Create a beautiful landscape beside Luoxi."

At the moment

The booster of the economy steady into quality

At present, Zhejiang is on the nodes where the economy is the most stabilized. Hangzhou is also trying to consolidate the momentum of the economic recovery and improve the quality of the economy.

Among them, investment is the "booster" and "cockpit stone" of gear acceleration; and government investment projects play a key guiding role. In Zhejiang, Hangzhou is an economic city and Yuhang is an economic area. At the moment when someone needs to be brave, Yu Hang is even more responsible.

The total investment of the Western Insurance Datang has reached 5.8 billion yuan.

In order to promote the construction of this project as soon as possible, the provincial and cities have established a third -level special class to establish a three -level linkage mechanism.

For example, the Western Insurance Datang's standard reinforcement project was completed in just 9 days, which was shortened by more than a month from the normal approval time limit. Because of this, the project that was originally planned to start at the end of September was started until the end of August.

Effective investment is the word "effective". Major water conservancy projects have the characteristics of wide coverage, large investment in investment, long industrial chain, and many opportunities for employment, and can give full play to the role of investment stretching and stabilizing the macroeconomic economy.

According to relevant calculations, every investment of 100 billion yuan in major water conservancy projects can drive GDP to increase by 0.15 percentage points and add 490,000 new jobs.

Driven by the super routine, the Western Insurance Datang reinforcement project is also the first national key water conservancy project in Hangzhou this year.

This is just a starting point. On the day of the Hangzhou major water conservancy project on -site dispatching promotion meeting, a total of 10 new major water conservancy projects were involved, with a total investment of 22.1 billion yuan.

Not only Yuhang, Hangzhou, but also Zhejiang in all parts of Zhejiang are underwriting the uncertainty of the external environment with the certainty of major project investment. Under the active guidance of government investment projects, investment confidence is recovering rapidly.

This is reflected in the data: From January to July this year, the investment in Zhejiang's fixed assets increased by 10.1%year -on -year, 4.4 percentage points higher than the country.

The refraction of Western Insurance Datang is not only a sense of urban safety, but also an opportunity for urban development. This is becoming clearer.
