Chapter 357 Supreme Command (II)
Egypt.
Due to the obstruction of the Nile River, the Southern Canal has only completed the double-track on the east side of the Nile River, and is currently undergoing a second widening.
After all, the river width of 120 meters is too narrow. When Evergreen Marine's container ship passed through the Suez Canal , it ran aground because the canal's water surface width was only more than 300 meters and the depth on both sides was not enough.
This is also the reason why the Egyptian Canal Management Company of Homo Sapiens limits the canal's navigation volume to 50,000 tons.
According to the plan, the main line of the Southern Canal has a single-line design width of 500 meters and a depth of 45 meters. It will need to be excavated at least four more times along the canal to ensure that the water surface width reaches 500 meters.
Fortunately, the New Luzon Shipyard and the Ceylon Shipyard will deliver 15 giant rhino-type canal-dredging ships in the next year, which will greatly increase the speed of canal excavation.
The north of Kom Ombo at this time.
There are not many large ships on the calm surface of the Nile River, mainly because the Nile River is in the dry season at this time, and the industrial and agricultural water consumption on both sides of the river is increasing year by year, resulting in the water depth of the Nile River being less than 5 meters at this time, which greatly affects its shipping value.
The Gobi Desert New District is located on the south side of the Southern Canal, on the east side of the Nile River, and 5.7 kilometers away from the main stream of the Nile River.
The person in charge, Hu Mingliang, and the leader of the planning team, Kamijo Kitayo, were standing on the bank of the Nile, examining how to make the canal pass through the Nile.
If it is a freshwater canal, there will be no need for too much trouble and it can be connected directly.
The problem is that the Southern Canal is a seawater canal. Once connected to the Nile River, since the altitude of this section of the Nile River is about 58 to 60 meters, and the Southern Canal is level with the sea level, the result is that the water of the Nile River will quickly flow into the Southern Canal, causing the lower reaches of the Nile River to directly dry up.
Hu Mingliang turned around and asked, "Kamijo, have you come up with a plan?"
"I have discussed this with the planners at headquarters. If the overhead bridge solution is adopted, the canal will only be able to accommodate ships under 100,000 tons."
Hu Mingliang took the tablet computer from Kamijo Kitano, which contained the design plan for the overhead bridge.
The specific plan is to build two super-large bridges above the canal, allowing the Nile River to pass through the bridges while the canal passes through the overhead bridges.
This solution is the most time-saving and labor-saving, and it also avoids the backflow of Nile River water and the pollution of fresh water by seawater in the canal.
Other ship lock schemes and four-sided dam schemes are not as good as the overhead bridge scheme.
Although the overhead bridge is good, its shortcomings are also very obvious.
The Nile River here is 58 to 60 meters above sea level, and the riverbed is 50 to 55 meters above sea level. If an overhead bridge is built, combined with the thickness of the overhead bridge, the height from the bottom of the bridge to the canal water surface will be compressed to about 40 meters.
With a clearance height of 40 meters, a 100,000-ton transport ship can barely pass through.
The design limit of the Southern Canal is 300,000 tons.
Hu Mingliang frowned and asked, "Is there any other way?"
Kamijou Hokuyo thought for a moment and said, "I have a more troublesome plan."
"Tell me about it."
Kamijo Kitayo pulled up another design on the tablet: "Build two seven-level ship lock-type overhead bridges, and at the same time dig a drainage tunnel to connect the upper and lower reaches of the Nile River separated by the overhead bridges."
Hu Mingliang looked at the new plan, which had expanded several times in scale, and was stuck in weighing the pros and cons.
In this plan, the overhead bridge passing over the canal will be raised to a height of 100 meters above the canal surface. The length of this section of the overhead bridge is 1 kilometer.
The bottom of the bridge is 100 meters above sea level, plus the 12-meter-thick bridge structure layer and 12-meter-deep water depth, which requires the dam height of the bridge to be about 30 meters, and the overall altitude is 130 meters.
There is a difference of about 70 meters between this height and the water level of the Nile River on both sides.
Therefore, three locks were designed on both sides to ensure that 50,000-ton transport ships can pass through the locks smoothly.
Two other locks were also designed to connect the Nile River to the Southern Canal.
Two drainage tunnels run through the bottom of the southern canal, connecting the upstream and downstream Nile, primarily to avoid blocking the flow of the Nile.
Obviously, the cost of this solution is several times higher and the complexity is also increased.
But the benefits are also very obvious. The Southern Canal can accommodate 300,000-ton transport ships without obstacles, which will have a very important accelerating effect on the future development of the Sahara Desert region by the Sapiens Company.
After weighing the pros and cons, Hu Mingliang decided: "Let's use the second option. It will be more troublesome to upgrade and transform it later if we search and click now."
"Okay then! I'll use the second plan as the basis and communicate ."
Hu Mingliang nodded: "I'll leave this matter to you."
Suddenly, Hu Mingliang's assistant came over and whispered something in his ear. He raised his eyebrows and shrugged to Shangjo Beiyang: "Something else has happened."
"Haha, it doesn't matter, you go ahead and do your work! I also need the geological survey team to survey the surrounding geology."
After saying goodbye to Kamijo Beiyang, Hu Mingliang drove the armored vehicle back to the Gobi Desert New District, and then hurried to his office.
There were two people in the office at this time.
A rugged old Slavic man, and a middle-aged man in a space gray uniform.
"Dr. Mikoyan! Major General Du Hai! Hello, I am Hu Mingliang, the person in charge of the Gobi Desert New District of the Egyptian branch."
Dr. Mikoyan, who previously worked in the aircraft manufacturing department of Aoba Aviation Group, has now been transferred to the Third Design Institute of Aoba Aviation Group.
"Hello! Hu, this time we are here to ask you for help." Dr. Mikoyan gave him a bear hug.
Major General Du Hai took out a piece of white paper and handed it to Hu Mingliang.
Hu Mingliang took it, tore off the special film on the surface, and read the special pheromone code on the paper through the pheromone decoder of the biochip.
After 30 seconds, the pheromones on the white paper had completely melted away , turning it into an ordinary piece of white paper.
Hu Mingliang, who had browsed the confidential information, replied seriously: "I understand. I will fully cooperate with your work and ensure confidentiality and cover-up."
"Thank you for your help." Major General Du Hai saluted.
Open a virtual map of the office.
Du Hai circled an area on the virtual map: "It's right here."
"The east side of the Jaje Manor in the Kharji Oasis area? No problem, but the southern canal needs to wait until the Nile River hub project is completed before it can be advanced to the Kharji Oasis area."
Du Hai asked: "How long will it take?"
Hu Mingliang thought for a moment and said: "It will take about 7 months to build the main ship lock and drainage tunnel. It is expected that the canal can be pushed to the Harij Oasis area by the end of this year."
After hearing the time, Du Hai quickly made a decision: "It seems that we must dispatch a batch of transport planes to the Harije Oasis area to make arrangements in advance."
Then he turned around and said, "Doctor, you and the planning team of the space base should stay in Kom Ombo for the time being! I will personally lead people to the Harije Oasis area. As for the planning and layout, we will communicate via satellite phone at that time."
"No problem." Dr. Mikoyan had no intention of going to the Kharji Oasis area now. After all, he was almost sixty years old and he would not be able to help much if he went there now.
After communicating for a while, the three of them left and started working on their own tasks.
The layout of the space base in Egypt this time was also one of Li Qingye’s instructions.
