Let s discuss where the Yanda undersea tunnel is most likely to be built in Penglai?

This has nothing to do with Hong Kong, you can look at the Huangdao Tunnel. I've been talking about this for years, and I feel a little hopeful.

I feel like it should be in the port of the development zone, where the conditions are good. Hey.

When I was in junior high school, Hangzhou said it was going to build a subway, and last year my son was in junior high school, and the Hangzhou subway finally started. The Hangzhou Metro proposal was in 1984, the plan was in 1993, the official start of construction was in March 2007, and the operation was in October 2012, during which nearly 29 years have passed. So, I want to wait for my son's son to go to junior high school, and I guess the tunnel should be put into use.

Attached data: Hangzhou Metro Memorabilia: In 1984, the relevant departments of Hangzhou began to study the rail transit plan of Hangzhou, and initially planned to build a light rail around the lake in order to solve the problem of peak passenger flow around the West Lake.

This is the beginning of the subway dream of Hangzhou citizens. In February 1993, the "Rapid Rail Transit Line Network Planning Plan" was completed, and it was determined that the Hangzhou rail transit network was composed of the east-west line and the north-south line. In May 1995, the "Pre-feasibility Research Report on the First Phase of Hangzhou Rail Transit" was completed, which further demonstrated that the line of the first phase of Hangzhou Rail Transit Project was a combination of the eastern section of the east-west line and the southern section of the north-south line in the "ten" line.

For the first time, it was proposed that part of the line (about 6 km) go underground, and the concept of "subway" in the true sense of the word was born. On June 6, 2002, Hangzhou Metro Group Co., Ltd. was established, and Hangzhou Metro Construction officially had its own organization. On December 26, 2003, the construction of Qiutao Road Station of the experimental section of Hangzhou Metro Line 1 started.

In March 2004, the final report of the Hangzhou Rail Transit Network Planning (Optimization) was submitted after several demonstrations, and nearly ten domestic experts including Zhou Ganzhi, an academician of the Chinese Academy of Sciences and the Chinese Academy of Sciences, carefully reviewed it. The final review was successfully passed, and the rail transit pattern of Hangzhou in the next 50 years was basically finalized. On June 1, 2005, Hangzhou City Rapid Rail Transit Construction Plan was approved.

On June 6, the state officially issued the "Notice on Approval of Hangzhou Urban Rapid Rail Transit Construction Plan". The approved near-term construction plan is the key section of Metro Line 1 and Line 2, with a total length of kilometers, basically covering most of the "one main and three subordinate" in the central urban area, connecting the city's main transportation distribution points and external transportation hubs. So far, the subway project, which has lasted for more than 20 years, has finally been a complete success.

On April 19, 2006, the National Development and Reform Commission issued the reply to the feasibility study report of Hangzhou Metro Line 1 project, which confirmed that the total length of the line 1 project is kilometers, and there are 31 stations on the whole line (excluding the reserved 2 elevated stations), a Qibao depot and a Xianghu parking lot, and a control center in Wulin Square. On September 15, 2006, all the winning bidders of the design were stationed in Hangzhou and began the preliminary design of Metro Line 1. From January 6 to 9, 2007, Zhejiang Province organized experts to review the preliminary design of Metro Line 1 project, and the preliminary design plan successfully passed the review, and the approval was officially issued on February 7.

On March 28, 2007, the first phase of Hangzhou Metro project officially started.

The Yanda Railway is not an undersea tunnel. Yanda Railway is a sea railway ferry, also known as "Yanda Tielingsen Road Ferry", the railway is 160 kilometers long, from Lushunkou District, Dalian City, Liaoning Province in the north, to Zhifu District, Yantai City, Shandong Province in the south. Regarding the specifics of "Is the Yanda Railway an undersea tunnel", if you are interested, you can continue to read and understand.

1. Yanda Railway is located in Yantai and Dalian, which is an important part of the "eight vertical and eight horizontal" coastal railways, which was completed in 2006.

2. The Yanda Railway spans the four major economic zones of Northeast China, Bohai Bay, Yangtze River Delta and Pearl River Delta, and is the first maritime railway ferry with more than 100 kilometers in China.

3. Yanda Railway is the longest cross-sea railway ferry in China, with a sea distance of about nautical miles, and the implementation of the "three ships and three pairs" mode of transportation.

4. The construction and opening of the Yanda Railway is a demonstration of the comprehensive technical level of China's railways, and at the same time, it has further optimized the transportation mode on both sides of the Bohai Sea.

There are many undersea tunnels in <> China, such as: Hong Kong-Zhuhai-Macao Bridge Undersea Tunnel, Xiang'an Undersea Tunnel, Jiaozhou Bay Undersea Tunnel, Guangzhou-Shenzhen-Hong Kong Shiziyang Tunnel, Qingdao Metro Line 1 Seafoot Zaomu Bottom Tunnel and so on.

As of December 2019, the opening time of the Yanda Undersea Tunnel has not yet been determined, and it has been submitted to the state for approval.

In May 2019, at the 2019 International Conference on Bridge and Tunnel Technology, Sun Jun, an academician of the Chinese Academy of Sciences, said that the internal research of the Bohai Bay cross-sea channel has reached a critical node, and the research team has completed the strategic planning research report of the channel plan and has submitted it to the state for approval, with a preliminary estimate of 300 billion yuan in project funds.

As of February 2019, the Bohai Strait cross-sea corridor has been included in the Outline for Cooperation and Development in the Bohai Rim Region, as well as the 13th Five-Year Plan for the Development of Shandong Province and the Medium and Long-term Development Plan for the Comprehensive Transportation Network of Shandong Province (2018-2035).

Not sure, it's still under approval.

The Yanda Undersea Tunnel, that is, the Yantai-Dalian Undersea Tunnel, has been rejected by the original "North Tunnel, South Bridge" plan, and finally decided to build a fully enclosed railway undersea tunnel.

In November 2015, the key projects in 2016 were officially reviewed, and the construction plan of the Yantai to Dalian undersea tunnel was officially released. After the tunnel is opened, it will only take a maximum of 40 minutes to travel from Yantai to Dalian.

The undersea tunnel from Yantai to Dalian refers to the undersea tunnel between Yantai Penglai and Lushun, which belongs to the management of the railway company, the whole tunnel is 123 kilometers long, the train design speed is 250 kilometers per hour, and the running speed can reach 220 kilometers per hour, and it will only take 40 minutes at most from Yantai to Dalian.

It is understood that the project plan will adopt the whole undersea tunnel scheme, with trains carrying cars, and the connection points and project scale at the north and south ends have also been determined.

At the 2019 International Bridge and Tunnel Technology Conference, Sun Jun, an academician of the Chinese Academy of Sciences, said that the internal research of the Bohai Bay cross-sea channel has reached a critical node, and the research team has completed the strategic planning research report of the channel plan and has submitted it to the state for approval, with a preliminary estimate of 300 billion yuan in project funds.

On March 6, Wang Mengshu, a deputy to the National People's Congress and academician of the Chinese Academy of Engineering, said in an exclusive interview that the Dalian-Yantai undersea tunnel project led by him is expected to report the inspection report this year. The Bohai Strait, which has been plaguing the transportation links between East China and Northeast China, is expected to start EMUs with a speed of 250 kilometers per hour in the future. After the opening of traffic, the travel time between Shandong and the three northeastern provinces has increased from more than 10 hours to only half an hour.

Construction of a fully enclosed railway undersea tunnel.

The reporter learned that the undersea tunnel project connecting Yantai in Shandong Province and Dalian in Liaoning Province has been demonstrated for decades. In 2005, Qian Qihu, an academician of the Chinese Academy of Engineering, said that in the next 20 to 30 years, China is considering building five cross-sea tunnels, including the Bohai Sea cross-sea tunnel.

Wang Mengshu told reporters that in 2011 and 2012, the state allocated 3.6 million yuan to support the investigation team of the major project Dalian to Yantai submarine tunnel project of the Chinese Academy of Engineering, led by Wang Mengshu and composed of 8 academicians, to conduct field research, marking that the project has entered the substantive demonstration stage. "We went down to the sea from Dalian and took a ferry to Penglai in Yantai, where a future undersea tunnel could be built on the seabed.

Wang Mengshu said that at first, the way between Yantai and Dalian was considered as a "south tunnel and north bridge", and the connection point was the island between the Bohai Strait. In terms of the way it will be opened to traffic, we have considered a tunnel project that can be passed by trains and cars, but the final decision is to build a fully enclosed railway undersea tunnel.

The planned speed of the train is 250 kilometers per hour.

The Dalian-Yantai Cross-Harbour Tunnel has been attracting attention from all parties for many years. At last year's National People's Congress and the National People's Congress, Liaoning Provincial Governor Chen Zhenggao expressed the hope that the project would start construction at an early date, so as to promote the economic leap of Yantai and Dalian again. Wang Mengshu said that within this year, 8 academicians will submit project demonstration reports to ***.

The technical difficulties of the tunnel, the safety issues, have now been solved. Wang Mengshu said that the Bohai Strait undersea tunnel is expected to be 123 kilometers long, with an average depth of 20 30 meters, the deepest is about 70 meters, and the planned speed of 250 kilometers per hour EMU, when the fastest time from the three northeastern provinces into East China will be about half an hour, for the current Yanda ferry, Dalian to Jinan train running time of one-tenth. "At that time, there will be more and more economic and trade exchanges between the three northeastern provinces and Shandong.

Wang Mengshu said.

Yantai and Dalian are two cities at this stage, the freight vehicles of the ferry are about 1 million times a year, and the passenger capacity is also more than 6 million, 90% of which come from the mutual flight between Dalian and Yantai. This indirectly shows that the two places are very closely related economically, but the transportation environment is limited. Once the undersea tunnel is established, the two places will evolve from the previous "transportation terminal" to a "transportation hub", and even directly radiate to the cities to which the two places belong.

This issue has been discussed for a long time, and the relevant experts have also completed the technical demonstration and design plan, and suggested that it should be implemented as soon as possible, so that the Yanda Undersea Tunnel can be completed as soon as possible and benefit the people, and help the country's economic and social development!

It is worth because the Yanhaihai Tunnel was built around the Bohai Sea, and the completion of the Yanhaihaihai Tunnel can save the need for cross-sea transportation.

Once the tunnel is built, the two places will change from "transportation terminals" to "transportation hubs", directly radiating to various cities in the two places. The most important thing about this undersea tunnel is to merge the C-shaped transportation of Bohai Bay into an "I" shape for direct transportation, which is a great change for the eastern region of China, and has a very positive effect on the revitalization of the economy of Northeast China and the strengthening of the eastern economy, which has a huge impact, which is the reason for the construction without hesitation.

It is worth doing this from an economic point of view, or from the perspective of raising the international level and building capacity.

Value, for express delivery, Liaoning, which originally took three days, is now sent to Shandong for a maximum of two days, and Heilongjiang has arrived for three days. It will effectively improve the living standards of Liaoning and Shandong, and the real estate **!
