At 6:30 on August 30, after more than half a year of free trial ride experience, Jinhua-Yiwu section of Jinyong City was opened in the early stage of operation, and the land of the thousands of years entered the new era of comprehensive transportation.

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. The line starts at Jinhua Station, the ending point is Hengdian Passenger Transport Center, consisting of Jinyi Duan and Yidong section, and two sections of the parallel dumplings at Qintang Station. There are 31 stations across the board. Among them, the Hengdian Passenger Transport Center Station that is suspended is reserved. The average station distance is 3.57 kilometers and the speed target value is 120 km/h. The operation uses the combination of large station express and station stop.

The total length of the Jinyi section opened this time is 58.4 kilometers, with 17 stations.起于高铁金华站，经由八一南街、万达广场、大堰河街、铁路金华南站、塘雅、综合保税区、金义都市新区、东华街、义亭、官塘下、环城南路、 Qintang, the main urban area of ​​Yiwu and Yiwu. From Jinhua City to Yiwu City, the fastest 36 minutes.

The rail transit of Jinyidong 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 time and space distance between the time and space provides a fast, convenient and comfortable public transportation service for residents along the route, and builds a 1 -hour traffic circle where private cars and buses cannot catch up.

During the construction process, the construction team first adopted the outer wall of the elevated station in the domestic decoration of elevated stations with prefabricated concrete three -dimensional three -dimensional exterior plates in China. Seven elevated stations with the theme of "Book Rhyme Jinhua", "Preparation of the Future" and "Embroidery Lake" were given More possibilities for concrete. For the first time, this line uses prefabricated concrete technology to apply for the barrier -free entrances and emergency evacuation of the underground station. The ground entrance and exit of the ground are built through the method of building blocks to provide new options for the station personalization.

Everlasting area indirect rail

According to the relevant person in charge of the Fourth Court of Railway Courtyard of Jinyi East City, as the longest in the country's use of DC rail transit, this line uses DC contact to power supply, which not only ensures the overall beauty of the interval line, but also reduces operational maintenance and maintenance work. quantity. By using 35KV (KV) decentralized power supply and oil -containing immersion isolation transformer, the line makes full use of the electricity resources along Jinhua City, which greatly saves engineering investment of external power.

Half -seal closed -premium cable bracket stem cover, underground shield range embedded sliding technology, high molecular composite interval evacuation platform and handrails, urban rail cloud platform architecture, water -cooled SVG without compensation device, optical fiber interconnection fire phone, assembly frozen frozen frozen freezing Site, all -in -one cold water units, magnetic suspension cold water units ... The innovative use of new technologies, new methods, and new equipment for a pile of technology makes Jin Yidong not only have a face value, but also a "innovative model" line with a sense of technology.

In the history of Zhejiang Local Railway, the Golden Yidong City Rail Transit Project created a new history: from the start of the project in June 2016, and the project feasibility research report in early November, it took only 5 months. This not only refreshes the speed of the early work of similar projects, but also sets a new record for engineering workers in the Fourth Court of Iron Hospital.

From the "Three Three Miles of Shuitong South" to the "first -line and three cities" in the future. As an important part of the urban rail transit network of urban groups in Central Zhejiang, the rail transit of Jinyi East City is becoming the fourth largest metropolitan city of Zhejiang Province. The urban construction booster provides transportation support for the construction of a modern urban circle and a common prosperity.
