September 14, 2022

Dongguan released the news,The other day,《Tender for Lump Sum Contract for Construction of New Shenzhen-Jiangmen Railway Station Works》And the issuance of tender announcement for construction supervision,The project is scheduled to start at the end of September.。

Shenjiang Railway is the national railway.“Eight vertical and eight horizontal”The high-speed railway network is an important part of the coastal corridor.,It is also the main cross-river inter-city corridor in the Pearl River Delta region.,It runs through Shenzhen in the Greater Bay Area、Dongguan、Guangzhou、5 cities in Zhongshan and Jiangmen。The total length of the main line is 116 kilometers.,The design speed is 250 kilometers per hour/Hour,Total estimated investment of the project 513.100 million yuan。

July 2, 2020,The First Section of Shenjiang Railway and the Pearl River Estuary Tunnel of the Control Project(DK39+905~DK53+Paragraph 595)Construction was officially started,The total length of the tunnel is 13.69 kilometers,The maximum water pressure in China at present、Subsea tunnel project with maximum buried depth,It is also the most difficult part of the whole project construction.,At present, the shield tunneling in the submarine section has exceeded 680 meters.。

However,Because the scheme of crossing the Pearl River Estuary is complicated.,The section from Shenzhen to Jiangmen has been delayed.。The focus of the controversy lies in,Whether to adopt the scheme of highway and railway bridge、Single bridge option or tunnel option。The design scheme has been compared and selected several times.,Finally, the highway and railway bridge was changed to tunnel underpass.。Previous analysis by scholars pointed out that,This section of the high-speed railway to the seabed, although the cost will be higher.,However, it has little impact on shipping.、Less affected by the weather。After the tunnel is completed,It takes only 4 minutes to drive from Nansha, Guangzhou to Dongguan.。

According to plan,The Shenjiang Railway will be completed in March 2028.,The space-time distance between the east and west sides of the Pearl River Estuary will be greatly shortened.。At that time,Shenzhen and Jiangmen can be accessible within one hour,Shenzhen Qianhai Free Trade Zone and Guangzhou Nansha Free Trade Zone will also realize half-hour high-speed railway interconnection.。

Not so long ago,Proposed by the 13th Party Congress of Guangdong Province,Strive to build 100 kilometers around the Pearl River Estuary“Golden Inner Bay”,Drive Guangzhou、Shenzhen、Coordinated Development of the Three Metropolitan Areas on the West Bank of the Pearl River Estuary、Gather momentum and take off。For this reason,The eastern and western sides of the Pearl River Estuary are speeding up the interconnection.——At present, four river-crossing channels have been built from north to south.,They are Huangpu Bridge.、Nansha Bridge、Humen Bridge、Hong Kong-Zhuhai-Macao Bridge;In addition,There are still 7 channels under construction and planning.,Including the Shenzhen-Zhongshan Bridge under construction、Huangmaohai Passage、Shiziyang Passage、Zhujiang Estuary Tunnel of Shenjiang Railway、Macau Light Rail Hengqin Line,And the Shenzhen-Zhuhai Passage under planning、Lianhuashan River-crossing Passage。

With the completion of more and more cross-river channels and tunnels into the sea,,The east and west sides of the Pearl River Estuary will gradually make up for the lack of high-speed rail or straight-line communication.,It is more conducive to the coordinated development of the Pearl River Delta and the East and West of Guangdong.。
