Qiongzhou Haipinhua Gorge is located between the Shouzhou Peninsula and Hainan Island in Guangdong Province, China, and is one of the three major straits in China. In addition, the Qiongzhou Strait is located in a low-latitude area, which belongs to the tropics, with a warm and humid climate, heavy rainfall, and frequent typhoons, so no sea-crossing bridge has been built here.

The Guangdong-Haihai Railway runs from Zhanjiang in Guangdong Province to Hai'an Town, passes through the Qiongzhou Strait cross-sea ferry to Haikou City, Hainan Province, and passes through Chengmai County and Danzhou City to Fork River Station along the West Ring Railway of the Fork River, with a total length of 345 kilometers, and is connected with the existing line Fork River to Sanya Railway. It is the first cross-sea railway in China. The Guangdong-Haihai Railway includes three parts: the Zhanjiang-Hai'an Railway in Guangdong Province, the Qiongzhou Strait Railway Ferry, and the Haikou-Chahe Railway in Hainan Province.

Among them, the Qiongzhou Strait Railway Ferry and the Nangang Pier Bridge are key parts of the Guangdong-Haihai Railway Corridor.

Train ferries. The "Yuehai Railway No. 1" is a train ferry designed and built by China itself, built by Shanghai Jiangnan Shipyard, with a total cost of 210 million yuan, a displacement of 12,400 tons, a design minimum speed of 15 nautical miles per hour, a total length of 165.4 meters, a width of 22.6 meters, a draft of 5 5 meters, and a vehicle weight of 4,080 tons. It is an open ferry, with three decks from the bottom to the top for loading trains, cars and passengers, and the main deck is the train deck. The lowest train deck has 4 strands of rails about 145 meters long, which can carry 40 freight trains each 14 meters long and weighing 80 tons, and 18 passenger trains each 26 5 meters long.

At the same time, the car deck on the second level can also carry 56 cars. The rear half of the ferry is equipped with a passenger cabin, which can carry 1,360 passengers. It can still sail under the sea conditions of level 8 winds, and within a year, it can be guaranteed to sail for about 350 days.

Nangang Trestle. Nangang Trestle Bridge is China's first self-designed and constructed cross-sea railway trestle bridge, which connects the land of Hainan at one end and suspends in the Qiongzhou Strait at the other end, and is the only bridge for trains to sail to Shanghai South Island. The whole trestle bridge is 95.35 meters long, and it is divided into four lanes and 22 meters wide corresponding to the "Guangdong Railway No. 1". The trestle is composed of three parts of civil engineering, steel beams and hydraulics, this trestle has a number of technologies for the first time used in China, there are three groups of six black hydraulic cylinders on both sides of the trestle, each group is 32.5 meters away, they are connected with three groups of lifting beams, each can bear 500 tons, in order to bear the weight of the trestle, and about 1,000 tons of trains.

Each black hydraulic cylinder is equipped with ten sensitive CIMS system probes, which transmit the trestle bridge data to two large computer systems located at the top of the trestle at any time. According to the real-time data transmitted by the submarine cable of "Yuehai Railway No. 1", as well as the water level and power flow measured by the probe in the fire plug rod of the hydraulic cylinder, the computer automatically adjusts the work of the six hydraulic cylinders and determines how several span beams are lifted, so as to adjust the height and angle of the entire trestle and complete the docking with the rails on the "Guangdong Railway No. 1". The accuracy error of this set of equipment does not exceed one millimeter, and the error of docking with the "Yuehai Railway No. 1" does not exceed 10 millimeters, while the error accuracy of China's railway standard is 40 millimeters.

Two trains with a total weight of one thousand tons can get on and off the ferry at the same time at a speed of ten kilometers per hour.

The construction of the Qiongzhou Strait is a big problem, it takes more than 100 billion, and some leaders think it is not worth it, which is also a difficulty in construction.

After 14 years of research and demonstration, the construction plan and timetable of the Qiongzhou Strait cross-sea project have been determined, and the cross-sea bridge will strive to start construction in 2012 and be completed and opened to traffic in 2020. The relevant departments will jointly invest in the construction of the Qiongzhou Strait Highway and Railway Bridge to achieve seamless connection of the land passage around the Beibu Gulf.

Hainan Province Qiongzhou Strait cross-sea channel project work leading group office said that by the Ministry of Transport, the Ministry of Railways and Guangdong, Hainan Province jointly organized the preparation of the "Qiongzhou Strait cross-sea project planning research report" has been completed, the report determined to build a highway and railway dual-purpose bridge connecting Dengloujiao in Xuwen County, Guangdong Province and Daolunjiao in Chengmai County, Hainan Province, as the preferred scheme for the Qiongzhou Strait cross-sea project, the length of the cross-sea part of the bridge will reach 26 3 kilometers, second only to the newly built Hangzhou Bay Bridge in the world.

The proposed Qiongzhou Strait Bridge will be divided into two layers, of which the railway bridge is designed to be 160 kilometers per hour and the highway bridge is designed to be 100 kilometers per hour. It is reported that the bridge will strive to start construction in 2012 and be completed and opened to traffic in 2020; The static investment of the project will exceed 20 billion yuan.

After the completion of the Qiongzhou Strait Bridge, it will only take 20 minutes to drive across the Qiongzhou Strait, while the current ferry crossing the strait takes about 5 hours to wait and travel. At the same time, Haikou, Zhanjiang, Guilin, Nanning, Beihai, Qinzhou, Fangcheng and other central cities around the Beibu Gulf will be connected by the highway network to form a 6-hour land transportation economic circle, which not only has an important role in promoting the economic and social development of Hainan, Guangxi and western Guangdong, but also has an important role in promoting the development of resources in the South China Sea, the implementation of the national energy development strategy, the strengthening of regional cooperation in the Pan-Pearl River Delta, the promotion of economic cooperation and development in the Beibu Gulf region, and the acceleration of the construction of the China-ASEAN free zone.
