The Jingyi high-speed railway, which is under design, starts outside the old city of Jingzhou and runs through the underground railway passage of Huaxia City, diagonally through the gap between Yichang and Yiling, and directly to the confluence of the Huangbai River and the Yangtze River.

Due to the special mountainous terrain, the confluence of the Huangbai River and the Yangtze River has formed a high-quality natural harbor with a water area of two square kilometers.

With only a little transformation, a giant ship of 10,000 tons can be docked here, which can at least meet the development needs of the world for a hundred years.

To the northwest of the Huangbai River is the mysterious Shennongjia Mountains, a treasure trove of natural wealth that I don't know.

As long as Wei Minsheng's power has gained a foothold in the real world, all kinds of resources in it will continue to be developed to provide him with financial resources for expansion.

Moreover, the location of Yichang is the location of the Gezhouba Water Conservancy Project in the real world.

If Huaxia conditions permit in the future, the construction of the world's largest low-head, large-flow, run-of-the-river hydropower station will not only improve the shipping conditions of nearly 200 kilometers upstream, but also provide hydropower resources of tens of billions of kilowatt-hours per year.

In addition, the Yangtze River is the most convenient waterway out of Sichuan in Shu Kingdom, and the place where Yichang is located is the throat of the waterway out of Sichuan.

As long as Yichang is controlled, the development of Shu will be controlled, and the rich natural resources of Shu will inevitably fall under the control of China.

Therefore, in this place, which can be said to be a cornucopia, it must be under the absolute control of the Huaxia Kingdom.

The railway from Jingzhou to Yichang is an important project to ensure that Huaxia can respond quickly to all affairs in Yichang, and it is also an important material flow trunk line in the western part of Yunmengze.

In addition, the artificial canal dug next to the railway, using the water potential of the Yangtze River, can save a lot of manpower by sending various agricultural products produced in the basin down the river and directly to Huaxia City.

With sufficient human resources and strong mechanical work capabilities, this narrow strip of land with a length of only 100 kilometers has gathered nearly 400,000 laborers.

In other words, even if the river digging and the railway construction are carried out at the same time, there are nearly 2,000 laborers on average for each kilometer of construction site, and there is a laborer for almost every meter.

The staff of Guangliang Surveying and Mapping Company used advanced surveying tools to mark the places where the railway and canal needed to pass.

After using computer engineering software to calculate the amount of excavation and filling in these places, the Ministry of State-owned Assets Supervision and Administration issued the project task based on the corresponding data.

Those people who have adapted to the way of working in Huaxia have spontaneously set up large and small engineering teams, and selected the task sections suitable for their participation according to the engineering tasks issued by the Ministry of State-owned Assets Supervision and Administration Commission.

The advanced engineering quality supervision system can allow the Ministry of State-owned Assets Supervision and Administration to take a break from the tedious quality supervision work and focus more on the overall planning of Huaxia instead of falling into the messy labor disputes in the real world.

Between Yichang City and Jingmen, it is bounded by Dangyang City, which is divided into two completely different terrains.

Most of the section from Yichang to Dangyang is steep mountains, and although the Changban slope outside Dangyang has been swept away, it only accounts for a small part of it.

With the current level of construction in Huaxia, it is not easy to repair this railway.

After the survey of Guangliang Surveying and Mapping Company, in order to reduce the amount of work on this railway, the Ministry of State-owned Assets Supervision and Administration decided to open a gap in the mountain range from Yichang to fill in the roadbed in the low-lying area from the gap to Dangyang City.

Then, on both sides of this earth-and-stone roadbed, a large number of quarries were built to cut all the areas that could affect the railway into slopes.

In addition to the artificial canal, all the waterways involved in the Yunmengze area that may affect the safety of planting, breeding and people's living will be built with stone embankments.

The 100-year plan is not guaranteed, but it is still possible to ensure that a flood that occurs once in 50 years will not be affected.

The project of moving mountains and filling valleys, such a huge project, can only be imagined and formulated with the support of sufficient financial resources such as Huaxia.

In the section from Dangyang to Jingmen, due to the special topography between the two mountain ranges, a large number of small rivers are densely packed in between, and a lake completely different from Yunmengze is formed in the west of Jingmen.

The lake, which is made up of clear mountain streams, is so connected that a large reservoir must be built to make use of it.

However, judging from the historical transformation of the real world, due to the complex terrain at the end of the mountain range, it is not easy to do this project well.

In the areas where Yunmengze has already developed, this thousands of square kilometers of delta formed by alluvial plains is enough to produce enough food for nearly four million people to survive every year according to modern farming methods.

The two water systems of the Yangtze River and the Han River, coupled with the Yunmengze water network that has been built, will not worry about the lack of water sources at all.

Under such circumstances, the input-output ratio of developing this complex lake was obviously not cost-effective, so the idea of building a reservoir here was rejected as soon as it was germinated.

However, this lake is connected to the former Yunmengze area, and if you don't find a way to solve the problem of water discharge from these lakes, once the rainy season is encountered, the railway between Dangyang and Jingmen will be very dangerous when a large amount of lake water is flooded.

Therefore, after repeated calculations and measurements by the Ministry of State-owned Assets Supervision and Administration and Guangliang Surveying and Mapping Company, and through the network platform, a variety of construction plans were proposed, and everyone's wisdom was used to make decisions.

The final decision was to build a 40-kilometer-long causeway from the foot of the mountain northeast of Dangyang City to the foot of Bailong Mountain in Jingmen.

The causeway acts like a gate that encloses the entire lake with complex topography and a railroad is built on top of it.

Nine large culverts were built in nine low-lying areas to discharge the flood water when the water rises in the embankment.

Since the lake has reserved a lot of space for activities, and the water source of the lake is not a large river, no matter how big the flood is, it is impossible to instantly raise the water level of this low-lying area that is five times larger than the area of the Zhanghe reservoir in the real world by several meters.

As a result, the nine large culverts, with a diameter of up to eight metres, are sufficient to cope with the demand for flood discharge under any extreme circumstances.

The flood outlet outside the culvert is directly connected to the Yunmengze water network through an artificial canal.

The Yunmengze water network was originally directly connected to the Han River and the Yangtze River, and the area was very wide, so the flood discharged from it did not pose any threat to the water network at all.

Just these projects set by the Ministry of State-owned Assets Supervision and Administration are expected to take two years to complete.

The Ministry of State-owned Assets Supervision and Administration is ready to use two years of investment to turn this Yunmengze Delta into the world's largest granary.
