The Yongjin Building 丨 spent more than 30 billion yuan, why is it not the subway?

On August 30, Jinhua -Yiwu section was officially opened to traffic in Jinhua -Yiwu section. At this point, the development of the four major metropolitan areas of Hangzhou, Yan, Wen, Wen, and Jinyi has the blessing of municipal rail transit.

The total length of rail transit of Jinyi East City is 107.17 kilometers. It is the longest -running rail transit project in the country and the largest project in Jinhua City.

Why is this rail transit so valued so much? And listen to Yong Jinjun slowly.

Metro and urban rail transit are a must -have for the development of urban areas and central cities.

Earlier, the three major cities in the province's Hangzhou -Nagaowen have successively opened subways, light rails or municipal railways. Shaoxing, Taizhou and even county -level cities have urban orbit.

In contrast, the "action" of the Jinyi Metropolitan Circle was slow.

Jinhua has always been a transportation hub in Central Zhejiang, and it has long been in history.

But for a long time, Jinhua's county and even township industries have been developing strongly, such as Yiwu, Dongyang Hengdian film and television industry, and the crystal of Yongkang's hardware and Pujiang. Moby "only eats left."

The opening of the rails of Jinyi East City is the first to improve Jinhua.

The total length of the Jinyi section opened this time is 58.4 kilometers, with 17 stations, 12 stations in Jinhua City, 5 stations in Yiwu, from Jinhua City to Yiwu City as soon as 36 minutes.

Obviously, the focus of Jinyi Duan lies in Jinhua.

From the map, you can find the "strange" look of this road -Jinyi East City's orbit is T -shaped, the Jinyi section is vertical, the Yidong section is one horizontal, and the two sections are changed in parallel island in Qintang Station in Yiwu City. take.

Among them, Jinyi Duan set up a new growth pole to the new growth pole of Jinyi Metropolitan New District in the Jinyi City New District and Yiting Station, but also left room for development to the Jinyi International Airport near Yiting in the future.

The subway is a high -end version of the urban orbit, but Jinyi has spent more than 30 billion yuan. Why only build a city orbit?

In fact, this is a choice made by the actual situation of local approval and economic, population and urban development conditions in accordance with urban rail construction.

The orbit of Jinyi East City is similar to the Wenzhou and Taizhou regional railways that were previously opened.

Different from the subway, there is a minimum restriction on the average station distances of urban orbiting. In principle, the average station distance is not less than 3 kilometers. The municipal railway cannot be densely set up like a subway, and the underground section cannot be roughly 30%.

This happens to be in line with the current status of a group of cities along the East Line.

According to Lu Jiayue, the person in charge of the design of the Jinyi East project of the III Court, the relevant planning and design adapt to local conditions. While fully considering the development prospects of the urban circle, a relatively good balance was achieved between the station distance and the passenger flow point, forming an internal densely set up station. There are few stations between the group.

The advantage of this is that it not only guarantees the high efficiency of travel between groups, but also expands the coverage of the passenger flow of the municipal railway, and it also has a certain sharing rate for the travel inside the group.

Therefore, it is not only a city railway, but it can also be used as half a subway, that is, short -distance stations in the urban area, and long -distance stations between regions, which not only serves urban commutes, but also takes into account urban transportation.

For example, the design planner of the Jinyi section designed a site with the cross line in each urban group, namely Dayan River Street, Donghua Street, and thick rivers.

The existence of these three sites makes it possible for the opening of the city express. At present, the fastest Jinyi room has arrived in 36 minutes.

Some people have doubts that Jinyi has originally connected the Shanghai -Kunming High -speed Railway and the Shanghai -Kunming Railway. There are more than 200 trains in the two places every day.

The speed is fast, and the high -speed rail is only 16 minutes; in the cheap, the Purakie Express is only 11 yuan, and the time is only thirty or forty minutes.

Even if the railway has not yet opened, it will pass after the opening of the Hang Wen High -Railway at the end of next year.

To put it simply, high -speed rail, National Railway Network, Municipal or Urban Rail is a transportation network that targets different traffic needs. The high -speed rail and the national railway network can quickly go to the distance, while the city's orbit can go deep into the streets, towns and towns, and enter the daily life of the people's lives.

High -speed rail stations are generally far away from destinations, and other means of transportation are required to transfer to their destinations. The generality of the municipal orbit is much better than the high -speed rail and ordinary iron, which can more conveniently serve the citizens in the city of Jinyidong.

Industry insiders believe that the rail transit of Jinyi East City is not only a commuting connection line, but also an industrial linkage belt. It connects railway hubs, Jinhua Business Center, Jinhua Science and Technology City, Comprehensive Free Trade Zone, Cainiao Town, Yiwu Central City, and other cities. The space -time distance between Jinhua and Yiwu and the future Dongyang.

Perhaps the urgent needs of cities along the Jinyi East, and the economic strength of meeting the project, "moved" the relevant approval departments, have always strictly strictly controlled the relevant parties of urban rail projects.

Many people do not know that the rail transit project of Jinyidong City has created a new history in preparation -the project was launched in June 2016. The project feasibility study report was approved in early November of that year. It only took 5 months to refresh similar projects. Early work speed.

What's more distinctive is that in order to reduce the impact on the landscape along the route, this rail transit uses DC contacts to power supply. There is no electrified railway and a common contact network in the rail.The overall aesthetics of the interval line, while reducing the workload of operation and maintenance.Because only 400V DC power supply is required, the line can also make full use of the electricity resources along Jinhua City, which greatly saves the engineering investment of external power.

According to the plan, the Yidong section of the Jinyi East urban rail will have the conditions for traffic during the year, and the lines of Jinhua to Wuyi and Yongkang in the second urban rails of Jinyi Metropolis have also been included in the vision plan.Essence
