China News Service, Wuhan, December 10 (Zhang Qishan) The Gan (zhou)-Shenzhen (Shenzhen) high-speed rail designed by the China Railway Fourth Survey and Design Institute (referred to as the "Tie Siyuan") was put into operation on the 10th.

Shang Yongtai, head of the Ganshen high-speed railway design, said that the line will provoke the Nanling Mountains at one end and the estuary of the Pearl River at the other, passing through basins, mountains, hills, and plains. During the design and construction process, ecology is always given priority and maximum Show the charm of Hakka culture to the limit.

　　According to Shang Yongtai, the Ganshen high-speed railway has a total length of 436.37 kilometers and a design speed of 350 kilometers per hour. The entire line runs through Jiangxi and Guangdong in two provinces and five cities.

After opening to traffic, the train running time from Ganzhou to Shenzhen will be shortened from the past 7 hours to about 2 hours, which not only greatly shortens the time and space distance between Jiangxi Province, especially Ganzhou City, and the Guangdong-Hong Kong-Macao Greater Bay Area, but also ends the lack of direct connections in southern Ganzhou. The history of Guangdong's high-speed railway has enabled Guangdong Province to achieve the goal of "city-to-city high-speed rail".

　　The Jiangxi-Shenzhen high-speed railway traverses a variety of landforms such as basins, mountains, hills, plains, and rivers, including many ecologically fragile and sensitive areas.

There are 155 tunnels and 319 bridges across the line, with a bridge-to-tunnel ratio of 87%.

The Longnan Tunnel with a total length of 10.24 kilometers is the “number one” major and difficult project of the Ganshen high-speed railway. It is a high-risk class I tunnel with a maximum buried depth of 580 meters. It crosses 12 fault zones along the line and faces high water pressure and large deformation of soft rocks. , Poor geological risks such as water gushing and mud inrush, the maximum daily water gushing volume reaches 18,000 cubic meters, etc.

　　In particular, the Dongjiang River, which needs to be crossed, is one of the four major direct currents in the Pearl River Basin. It is an important source of drinking water and a key water quality protection area in Guangdong and Hong Kong, sending high-quality domestic water to tens of millions of people.

For this reason, the design team insists on putting "zero pollution and water quality" as the first priority. Most bridges span the river with one hole, reducing the setting of water piers and avoiding river bank damage caused by construction; Tonghu Bridge is the longest bridge on the entire line, passing through Tonghu Lake National Wetland Park.

In order to meet the requirements of wetland protection, the wading bridge piers were constructed with steel cofferdams and set up with mud sedimentation tanks during the construction process, and the river water pollution was reduced by centralized collection of drainage pipes, and finally "the river is smooth, the water is clear, the bank is green, and the scenery is beautiful". .

　　At the same time, the Gan-Shen high-speed railway runs through the important areas of Hakka culture and is a "root-seeking journey". The line design also maximizes the charm of Hakka culture.

The Longnan East Station designed by Tie Siyuan adopts the design concept of "Shuanglong Gathering, Gannan Gateway", drawing inspiration from Longnan Enclosed House, and interpreting the new Hakka charm of Longnan East Station with the image of the deep overhang of the Hakka folk house enclosing house.

Its large curved roof is like a huge enclosed house, which encloses the four-lane bridge. Above the bridge is the platform and under the bridge is the waiting hall. The upper and lower entrances and exits are all in the enclosed house, just like living in an enclosed house.

As the largest station on the entire line, Huizhou North Station has a station building area of ​​50,000 square meters. The building vividly extracts the undulating momentum of Luofu Mountain. The curved glass in the middle supports the red bucket arch, and the horizontal lines on both sides are like layers. The wings of swan show the momentum of the take-off of Huizhou "Goose City".

　　In addition, the Jiangxi-Shenzhen high-speed railway is also a veritable road to revitalization.

The southern Gansu area through which the railway passes belongs to the poverty-stricken area of ​​Luoxiao Mountain. It is not only the “cradle” of the Republic, but also a key national poverty alleviation area and an old revolutionary base. The opening of the Ganshen high-speed railway will promote the rapid development of the economy and tourism industry along the route; Ganzhou is known as the “world orange”. Township", not far from Ganzhou West Station, there is a large-scale navel orange picking base. The opening of the Jiangxi-Shenzhen high-speed rail will enable more Gannan navel oranges to leave the orchard and head towards the Greater Bay Area; Gannan is also the country’s largest rare earth metal production base , Is a veritable "kingdom of rare earths". The opening of the Ganshen high-speed rail will open up the transportation bottleneck to help regional development and install a new engine for the regional economic integration and development of southern Jiangxi and the southeast coast.
