To start the construction of the railway, there are 3 landmark project nodes worth paying attention to, that is, research approval, preliminary design approval and construction bidding, and often there will not be too much uncertainty between the preliminary design approval and the construction bidding, the key is the feasibility study approval and the preliminary design approval, because the work content of these two stages is very complicated, the interests involved are different, and there are naturally more aspects that need to be coordinated, so the time spent and the uncertainty brought about by it also increase accordingly.
Among the railway projects planned to start construction this year, many key high-speed rail projects have been approved for feasibility study, but there are not many high-speed railways that have approved preliminary designs, and most of them are still in the stage of advancing preliminary design approval. However, if some railway expansion and renovation projects are included, as far as the editor knows, preliminary designs have been approved for 8 railway projects this year.
With the advancement of various railway projects and the gradual approach of the end of the year, some railway projects that have been approved for feasibility study have begun to receive news of preliminary design approval. No, there are 2 (section) high-speed railways approved for preliminary design in October, this article will introduce you to these 2 new approved preliminary design high-speed railways, and will also introduce you to the other 6 railways that have been approved for preliminary design during the year.
Wuzhang section of Lanzhang high-speed railway
This month's approval of the preliminary design of the high-speed rail is the Wuzhang section of the Lanzhang high-speed railway and the Jiangyin station to Huishan station section of the Yantai-Xichangyi railway, which also represents that these two (sections) of high-speed railways have made significant progress in phases and are closer to starting construction within the year.
Wuwei to Zhangye section of the high-speed railway is in June this year to obtain the feasibility study report approval, the whole line of preliminary design approval also represents the two most critical links of the high-speed rail have been successfully completed, it is also the mainland this year after the Miansui section of the railway, Longlong high-speed rail Wuping to Meizhou section of the third line approved the preliminary design of the line.
The new main line of the Wuzhang section of the Lanzhang 34 Line is about 244 kilometers long, with a design speed of 250 km/h, and 6 stations on the whole line, including Wuweidong, Zhuwangbao, Jinchangnan, Qilingxi, Shandan North and Zhangye West, with a total estimated investment of 24.855 billion yuan.
The Yanyi high-speed railway approved this month is the preliminary design of the section from Jiangyin Station to Huishan Station, although it is not the preliminary design of the whole line, but it is also a major progress of the Yanyi high-speed railway, and the approved section is expected to start construction in advance.
The feasibility study report of the section from Jiangyin Station to Huishan Station approved this time has been approved as early as 2021, with a total length of about 33 kilometers, starting from the north of Jiangyin Station, passing through Yuecheng Town, Jiangyin City, Huishan District, Wuxi City, and ending at Huishan Station of Shanghai-Nanjing Intercity Railway. At present, this section is being promoted along the line as a pre-construction section, and it is planned to start construction before the end of December.
Miansui Inner Railway
In addition, there are two high-speed railways in this year that have approved the preliminary design, and both have officially started. Among them, the Miansui section of the Miansui Railway was approved for preliminary design at the end of February this year, the construction bidding was launched in mid-May, and the construction started in July this year. The railway has a design speed of 250 km/h, starts from Mianyang South Railway Station, passes through Mianyang Fucheng District, Santai County, Suining Shehong City, Daying County, Chuanshan District, Anju District, and ends at Suining High-tech Station.
The preliminary design of the Wuping-Meizhou section of the high-speed railway was approved in June this year, and the construction bidding began in July, and the construction started at the end of August. The design speed of the high-speed railway is also 250 km/h, and there are 5 stations on the whole line, including Wuping, Jiaoling, Yanyangxi, Meizhou and Meizhouxi.
Jiamusi to Tongjiang Railway
In fact, in addition to high-speed rail, there are also 4 railway projects that have also obtained preliminary design approval and started construction this year in terms of intercity railways and railway capacity expansion and transformation.
One of them is the Jiamusi to Tongjiang railway expansion and renovation project, the project is approved in March this year of the preliminary design and construction drawing design, officially started in May, one month earlier than the expected start time. The total length of the line is 258 kilometers, starting from Dongjiamusi Station in Jiamusi City and ending at Tongjiangbei Station, and is planned to be completed in 2027.
The Putian-Changle Airport Intercity Railway (F2 Line) and the Ningde-Changle Airport Intercity Railway (F3 Line) Changle Airport Section are also the preliminary designs approved this year, and the construction bidding began in early September, and the construction started this month. The project has a design speed of 200 kilometers per hour, and the Changle Airport section is mainly composed of Changle North Tunnel and Changle South Tunnel.
Longyan Railway
The preliminary design of the Longyan Railway Municipal Transformation Project was approved by Shandong Province this year, and the construction bidding was launched in early September, and it is planned to start construction at the end of that month. The line starts from Yantai Dajijia in the west, and reaches Zhifu District, the main urban area of Yantai City in the east, using the existing Blue Smoke Railway and Longyan Railway, and builds a new branch line of Yantai Penglai International Airport, with a design speed of 160 km/h, and a total of 10 stations on the whole line.
