Many people want to know why a cross-harbour tunnel should be built instead of a cross-sea bridge. I will answer it for you according to my understanding. Compared with building offshore bridges, building cross-sea tunnels has many advantages. For example, the cross-harbour tunnel does not occupy land, and the amount of demolition is small, which does not affect the landscape, the ecological environment, navigation and bad weather such as strong winds and fog. It is a very safe all-weather waterway.
Although bridges are more economical, they have a greater impact on the ecological environment and landscape, and their ability to resist natural disasters such as earthquakes is not as good as that of cross-harbour tunnels.
For example, in some places where the weather is complicated, the cross-harbour tunnel will greatly improve the traffic efficiency and promote the local economy after opening to traffic.
In many places, weather, economy, ecology and other factors are integrated to decide which traffic construction mode to adopt. Quanzhou is naturally the same.
It is reported that the East China Sea Passage is designed according to the urban trunk road, with six lanes in two directions and a length of about 4.235km. It mainly serves the east-west urban traffic connection in the core area around Quanzhou Bay, and there are no freight vehicles. Large vehicles are mainly buses and buses. . Upon completion, the passage will become an important fast-track connecting Quanzhou Donghai, Shixian and Xibin City, and will also cross the banks of Jinjiang River to ease the traffic bottleneck and reduce the traffic pressure of Jinjiang Bridge.

Some time ago, the Quanzhou municipal government recently held a preparatory meeting for the East China Sea Passage, informing Quanzhou that it would build the first submarine tunnel, the East China Sea Passage, and basically defined the technical scheme and route direction of the East China Sea Passage. It is reported that the subsea tunnel will be built by Quanzhou Jiaofa Group.
So why should Quanzhou build a cross-sea tunnel? First of all, building tunnels can reduce the driving distance of vehicles and the construction cost of roads, and shorten the distance between roads and railways. Reduce driving time, thereby increasing passenger flow and developing transportation network. Secondly. The construction of the subsea tunnel does not need much land occupation and demolition, and it will not affect the landscape, ecological environment, navigation and bad weather such as strong wind and fog. It is a very safe all-weather waterway. Finally, the important reason for building the East China Sea Passage is to ease the traffic congestion across the river. The traffic pressure of Jinjiang Bridge has been too high.
It is reported that this cross-sea tunnel starts from the easternmost part of Dongtuo Phase II of Shuanglong Road in Jinjiang (from Xiedu Road to the coastal passage), then passes through Jinjiang coastal passage, Jinjiang River bottom and Quanzhou coastal passage, and ends at Donghai Binhai Street in Quanzhou. According to the planning idea, the East China Sea Passage is planned to be designed according to the urban main road, with two-way six lanes and a total length of about 4.235 kilometers. According to the design speed of 60 kilometers per hour, it only takes about 4 minutes to cross the tunnel. After the completion, it will alleviate the bottleneck of river-crossing traffic to a certain extent and become an important channel to alleviate the traffic pressure of Jinjiang Bridge.
The urbanized population of six districts in Quanzhou (Taitou District and Quanzhou Development Zone) is less than 1 10,000. Ten thousand years later, instead of building a subway, build the seabed.
Glad to answer this question!
If you want to build a road before you get rich, there is a general rule of one road. The current plan of Quanzhou government is to build Quanzhou East Sea Cross-sea Passage (Donghai Tunnel). At present, Quanzhou has vigorously developed the East China Sea, and four teams, including Quanzhou government, have moved to the East China Sea. The opening of the cross-sea tunnel has also strengthened the integration of Quanzhou and Jinjiang, and created Quanzhou Bay Binhai New City.
The East China Sea Passage is located at the mouth of Quanzhou, which can ensure the normal traffic of cars and will not destroy the current landscape of the East China Sea.
Whether it is a cross-sea bridge or a submarine tunnel, it is necessary to choose the shortest distance on land for construction, just in case and avoid danger.
In order to raise housing prices, this is the key point, otherwise where will the money for building tunnels come from? When house prices go up, so does land prices.
Pay more attention to people's livelihood,
Why did Quanzhou build a cross-sea tunnel? You wouldn't believe it. It is really an increase in knowledge.
We all know that "to get rich, build roads first", but for coastal cities, getting rich may mean building bridges or tunnels. 20 171February, Quanzhou held a preparatory meeting for the construction of the cross-sea tunnel. Why did Quanzhou build a cross-sea tunnel?
Geographically speaking, Quanzhou is located in the southeast coastal area of China and belongs to Fujian Province. The advantage of building a cross-sea tunnel is that it can expand the area of Quanzhou, making the city of Quanzhou not only develop on land, but also expand to the area under the sea. Judging from the function of the cross-sea tunnel, according to the authoritative statement of relevant experts, the total length of Quanzhou cross-sea tunnel is about 4.235 kilometers, which will become an important driving force for Quanzhou's traffic development.
The underwater area that the tunnel extends is just one of the many benefits of building a tunnel. Quanzhou, as an important trading port from ancient times to the present, has been prosperous in freight volume, and ships and vehicles coming and going from time to time carry a lot of goods. With the continuous development of economy and the continuous progress of cities, the original urban construction can no longer bear such a rapid development speed, and traffic congestion is an unsolvable problem. Building a cross-sea tunnel can greatly alleviate the traffic pressure on the ground to some extent. And in bad weather such as typhoon, traffic can be carried out normally, and it is not affected by climate and other factors, and the economic development of Quanzhou will not be affected by external factors such as weather, which can greatly improve efficiency.
Although tunnel construction may encounter great economic pressure and many technical problems to be overcome, there will be greater motivation if there is pressure. Under such pressure, China's tunnel transportation industry will make great progress and set up another great monument for China to become a powerful country in science and technology. Quanzhou will become the leader in the development of China subsea tunnel and further lead the tunnel industry to make great strides forward.
Moreover, Quanzhou cross-sea tunnel disperses the traffic pressure on the seabed, and avoids the hidden danger of destroying the above-ground ecological environment. Moreover, it is not easy to solve the interest disputes arising from land construction if a bridge is built. After all, the geographical area of Quanzhou is not very large.
From this point of view, the construction of Quanzhou subsea tunnel can save land resources and open up a new prospect for the further development of China subsea industry, which is not only related to the economic development prospect of Quanzhou, but also closely related to the overall development of China.
Before the country decided on this important event, it must have been carefully considered and planned before the Quanzhou Tunnel was built. All this shows China's great country demeanor and good desire for progress.
It is necessary, necessary and certain to strengthen the contiguous development of Quanzhou City, Jinjiang District and Taitou District and build tunnels.
