There are new progress!Guangzhou 40 minutes to Shanwei, 90 minutes to Zhanjiang

On September 13, Guangzhou made breakthroughs in the construction of two high -speed rail in eastern Guangdong and western Guangdong.

In the morning, the "Yongxing" shield machine of the Guangzhan High -speed Railway Zhanjiang Bay Oceanic Tunnel successfully crossed the main channel of Zhanjiang Bay, marking the successful overcome of the new technical difficulties.

In the afternoon, the successful dragon of the Zengjiang Extra Bridge of the Guangshan High -speed Railway marked that the project construction will enter the entire track laying stage.

Guangzhan high -speed rail: successfully crossed the main channel of Zhanjiang Bay

Zhanjiang Bay Oceanic Tunnel is a controlled project of the Guangzhan high -speed railway, with a single hole and double line. Among them, the shield section is 7551 meters, the shield excavation diameter is 14.33 meters, and the outer diameter of the tube is 13.8 meters. Wearing a high -speed rail shield tunnel.

It is understood that the main channel of the Zhanjiang Bay Underwater Tunnel this time is 195 meters long. It is the most important maritime transportation line in Zhanjiang Bay Sea. The size of the cover is under pressure, and the construction difficulty and risk are high.

After the Guangzhan high -speed rail was opened to traffic, it achieved 90 minutes of Guangzhou Zhanjiang

The full line of the Guangzhan high -speed railway is about 401 kilometers. The line starts at the Guangzhou Railway Station. It passes through Foshan, Zhaoqing, Yunfu, Yangjiang, Maoming, Zhanjiang and other cities.

The total investment is estimated to be 99.8 billion yuan, and the design is 350 kilometers per hour.

The successful crossing of the main channel of the Zhanjiang Bay Sea Tunnel marks the entry of the "acceleration" of the Guangzhan high -speed rail project, which also means that Zhanjiang has taken a substantial step forward.

After the Guangzhan high -speed rail is opened to traffic, it will realize the 90 -minute interoperability from the central urban area of ​​Guangzhou to the central urban area of ​​Zhanjiang, which will have an important role in promoting the joint development of the Guangdong -Hong Kong -Macao Greater Bay Area at high speeds in western Guangdong.

Guangshan High -speed Railway Zengjiang Extra Bridge Successful Heilong

The Guangshan High -speed Rail is one of the key projects in Guangdong Province. It starts from Guangzhou Xintang Station and eventually reaches Shanwei Station.

The Zengjiang Extra Bridge is a dual -tower and double cable surface concrete stagnation bridge, which is a key control project of the Guangshan high -speed rail. The bridge is 2569.480 meters in length, and the bridge is mainly across 260 meters. It spans the Zengjiang waterway. The main tower adopts a 100 -meter H -shaped bridge tower.

The main bridge has been constructed for the first time in the construction of the high -speed railway cable -keeping bridge around the world. This innovative technology has become a new benchmark for domestic high -speed railway construction.

After the Guangshan high -speed rail is opened to traffic, the fastest 40 minutes from Guangzhou to Shanwei

The Guangshan High -speed Railway Unicom, Beijing -Guangzhou, Beijing -Hong Kong high -speed railway and coastal railway are important parts of Guangdong Province's "five vertical two horizontal" high -speed railway network.

After the Guangshan High -speed Railway is opened to traffic, the trip time from Guangzhou to Shanwei will be compressed from the current 2 hours to the fastest 40 minutes. It is of great significance to accelerate the integration of coordinated development in the Guangdong -Hong Kong -Macao Greater Bay Area and promote rural revitalization.
