Dongxilian Island is located in the sea east of Lianyungang. Looking north from Lianyungang, there is a long island lying in the blue waves. This is Dongxilian Island. The total area of ​​Dongxilian Island is only 76 square kilometers. It is the largest island in Jiangsu Province. It was called Liandao in ancient times. Yingyou Mountain is the largest island in Jiangsu Province. Other book friends are reading: Xianzhong txt download. The mountains on the island are twists and turns, with peaks and ridges surging, arranged like a picture screen, just like a beautiful sea screen, blocking the waves from the Yellow Sea Strong winds and huge waves.

After the opening of Lianyungang, this island, with a maximum altitude of only 174 meters and facing Yuntai Mountain across the water, guarded the entrance and exit of Lianyungang day and night like a loyal guard, confronting the tall peaks. It has become the two barriers between the north and the south. The middle gate is about 6 kilometers wide and looks like a sky tower. This is where the main port of Lianyungang goes to the sea - Yingyou Gate.

Throughout the ages, the charming scenery here has attracted many literati and poets. In the past few years, hundreds of fishermen on the island have been moved out of this place. This sea screen has since become a purely fortress-like island, and in After the establishment of the Jiangsu Army and Marine Corps, it became its home port. Its importance is by no means inferior to Qingdao. Unlike Lianyungang, which is the largest civilian port, Liandao Wharf was first established as a merchant ship berth area and later developed Become an exclusive base for the Army and Navy.

After the Liandao seawall was built and the design of the seawall was fully verified, Lianyungang, a half-stone and half-mud port, not only was not affected by the siltation of the old Yellow River mouth in the north and the coastal sandbanks in the south, but also relied on The seawall channel, which is only two hundred meters wide, has formed a natural ocean current impact. Not only has a deep-water channel leading to the north been naturally formed, but the originally limited water depth of the Liandao Wharf harbor has also been naturally deepened. At the beginning, the water depth of the wharf was only 7 meters. , it can only berth 7,000-ton warships. After two years of deepening impact of sea currents, the water depth in the port area has been deepened from 7 meters to at least 12 meters. It can berth various large warships, and with the natural impact of sea currents, the water depth in the port area has increased It is still being deepened, and all of this provides sufficient natural guarantee for Liandao to form a complete naval foundation.

Whether it is a fortress or the home port of the Army and Marine Corps, it has been a restricted area for ordinary residents for two years. Even the so-called seawall bridge is guarded by soldiers and civilians are prohibited from entering the island. After experiencing the approach of the Japanese navy, After the crisis, the fortress fort on this island and the Yuntai Mountain fortress fort formed the maritime barrier of Lianyungang, but it is well known that the real maritime barrier lies in the navy and the warships.

Whenever a ship sails into Takayomon, merchant ship crews will always see the two captured Japanese warships "Dinghai" and "Pinghai" moored at the berth. At first, these two warships were alone. , and in the past year, with the addition of escort ships one after another, this fleet, which once had only two combat ships and one light cruiser, is beginning to show its scale and is developing step by step into a real fleet. fleet.

No one has any doubts about the future of this fleet. Perhaps, compared to the Central Navy, this fleet is difficult to obtain financial support from the national treasury. It only relies on millions of dollars in funding from Jiangsu Province to barely maintain its operations. , financial resources seem to be the key to limiting the development of this fleet, but what really supports this fleet is the "special coastal defense fee" levied by the attachments along Longhai. The fleet once threatened Lianyungang. The special fees agreed to be levied are only used to strengthen coastal defense. It is the investment of tens of millions in special coastal defense fees every year that supports the operation and expansion of this fleet, and along the Longhai coast With the development of industry and commerce in the affiliated areas, the amount of special coastal defense fees is also constantly increasing...

It is precisely with the guarantee of sufficient funds that after the establishment of the Jiangsu Army Navy, it was able to continuously expand the fleet and implement fortress transformation of the island. In the past two years, the fortress transformation of the island was often an external fortress.

The inner harbor-style fortress was transformed into a fortress on the seaside side and the port area was on the inner side. However, all this changed half a year ago. Half a year ago, as many as ten thousand labor corps stationed in Liandao and began to build a stronghold on the east side of Liandao.

A new fortification project was built in the coastal area.

Yingyou 02 Fort, located on the top of the mountain, is one of the most important core forts in Liandao Fortress. This fort is actually composed of twin 356mm turrets salvaged from the Japanese battlecruiser "King Kong", although its firing range has been damaged

The impact of the mountain is, in fact, an intentional design by the German fortress engineers. Its purpose is to protect the turret from direct sightings from the north. At least the north side sighting is provided by the observation post located on the top of the mountain. This kind of

The design can not only form protection for the fort, but also form a fatal straddle fire on enemy ships, and can form direct firepower in the southeastern sea area, thus compensating for the firepower gap of the 01 fort. The multiple forts on the island are precisely through

This mutual compensation forms a powerful fortress firepower. The latest chapter of a good-looking novel: The Wanted Stick in Online Games.

Although, in the past two years, this fortress has been continuously strengthened, and there are even rumors that the island has been hollowed out, the powerful fortress has never been put into actual combat, and if it is different from the past, the initial fortress on the island

After the transformation, the construction focus of this island also changed with the entry of the army and navy, from a fortress to a port. But even so, it is the most deterrent to any fleet trying to break into this place.

Yes, it is still these forts, and thanks to the good view of the forts, it is also the first choice for many people to visit this "Navy Island" that integrates military ports, fortresses, and naval schools. Of course, if he is authorized

Next, you can naturally come to these strictly confidential areas.

It may be difficult for others to get permission to enter the fort area, but as the Prime Minister and the real "owner" of this fleet and the fort, Li Zicheng naturally has the right to enter any place on the island. At this time, standing at the 02 Fort

On the pedestal made of thousands of tons of reinforced concrete, Li Zicheng had no interest in the four supporting tubes placed in the camouflage shed in front of the fort. If it was two years ago, he might have had some interest in them.

Come, but now, what he sees is Suma Bay. The beach that was once carefully constructed as a "trap" was attracted. At this time, the golden beach that once made him linger and look back has long changed.

, instead it turned into a lime-gray color. The huge reinforced concrete building looked a bit abrupt in the green, but it also had a different kind of beauty.

"Prime Minister, the Suma Bay submarine fortification can accommodate twelve submarines!"

Pointing to the submarine fortifications under the fort, Shen Honglie's tone sounded extremely confident.

"With these submarine fortifications and the fact that this area of ​​the sea is a fan-shaped restricted area, it will be difficult for the outside world to discover that we already have submarines!"

The fan-shaped restricted area is an artillery practice area that is dozens of kilometers away and is demarcated at 4 degrees and 75 degrees from the east and west points of the island to facilitate artillery drills after the fortress was built. The restricted area formed by the initial artillery drills is

The current submarine base provides the best cover.

Submarine fortification, Yuqinzhai txt download!

When he heard these four words, Li Zicheng smiled slightly. While providing the submarine drawings, he also provided the design plan and construction system and related drawings established when building the German submarine base during World War II. Originally, that only

It is just a supporting project, and now the submarine fortification has become a weapon of confidentiality.

During World War II, the German Navy relied on the help of submarine fortifications. While protecting submarines, it also made it impossible for British and American intelligence agencies to find out the truth about its submarine force, let alone how many submarines sailed on the sea every day, and whether there were submarines in the fortifications.

.….

"Prime Minister, in order to ensure the confidentiality of the construction. During the construction of the submarine fortifications, the Labor Engineering Bureau of the ** Company was initially responsible for this task. For this purpose, the company assembled a large number of outstanding construction workers. In addition, more than a hundred of the Navy's own

Engineering and technical experts supervise the quality of the project. On average, each submarine cavern project requires more than 15,000 workers. The construction implements a 12-hour work system. The workers work in two shifts to maintain uninterrupted 24-hour construction. Night construction is carried out by

Searchlight. Only during typhoons will construction be temporarily interrupted.

Of course, many subsidiaries were involved in the entire project. Several companies, such as United Concrete Company, contracted the concrete supply project. The construction of electric facilities was handled by the electric power company, and the task of machinery production was handled by General Machinery Company.

Contracting. The company provides concrete pouring machinery for the project for docks and docks. In addition, some small projects are handed over to a number of related companies, which are strictly selected to ensure the confidentiality of the fortifications..."

After observing the appearance of the entire submarine fortification from the fort, at Li Zicheng's suggestion, the group of people walked along the mountain path towards the lift into the submarine cave. After entering the lift, Shen Honglie started

He made a report on the submarine base. It can be said that it has been the most important infrastructure project of the Marine Corps from last year until now. It was under his attention that the Suma Bay base was able to be completed before the submarine was completed.

And can be put into use at any time.

"... After the site selection is determined, the construction of the base begins. First, the construction site must be carefully cleared in order to excavate the foundation and build giant steel piles. In order to prevent seawater from pouring back into the construction site below sea level, a giant cofferdam must also be built

.While excavating and constructing, a concrete platform must be built behind the dock, which is where various workshops are located. My Gangster Fiancé txt download. In addition, steel reinforced walls must be built. Building a submarine cave requires a large amount of materials.

, workers have to pour thousands of square meters of concrete every day. The most important materials, steel and cement, are continuously transported by railway from Lianyungang and throughout Longhai to various construction sites every day."

When Shen Honglie reported, Li Zicheng, who had already entered the passage, was surprised by the scale of the original cement-colored passages in the submarine base. They were wide enough to drive a truck, and in the center of the passage, there was a track that went into the ground, which was obviously for internal use.

The rail car is running. Different from the white-painted caves that we have seen in later generations, everything here maintains the original color of concrete. I don’t know whether it is for cost-saving or other purposes.

"... Of course, sometimes for the purpose of reducing construction costs, we directly send officers and soldiers to operate cement pump ships, load concrete directly from concrete suppliers in the port, and then pump cement directly to the construction site from the sea.

Sea distances are also used to facilitate the transportation of tens of thousands of tons of steel, cement and gravel. Even cement is packaged and transported in 50-kilogram capacity paper bags. Since the demand for cement is very huge, workers also need to pay attention to the unified recycling of used paper bags to achieve

Reuse…”

While Shen Honglie was reporting, Li Zicheng looked at the base carefully.

"Is this connected to the fortress?"

"Back to the Prime Minister. There are a total of seven connecting passages between the fortress and the submarine base. However, the interconnected passages can be blocked at any time through man-made sabotage. The internal passages of the Liandao Fortress have been designed with these issues in mind...

…”

Nodding, Li Zicheng motioned for him to continue the report.

"In addition to providing docks and shelters for submarines, the submarine cave also has repair workshops, power stations, pumping stations, warehouses, offices and dormitories, ventilation and heating devices, telephone and communication stations and other facilities. For safety reasons

, arms and ammunition such as torpedoes are stored in the fortress mountain ammunition depot outside the submarine cave. Those ammunition depots are located thirty meters below the sea level, and the top of the warehouse is protected by at least 60 meters of stone bedrock. If

When needed, it can be quickly transported through the internal transport rail car and shipped along the dedicated channel. The loading and unloading time from the ammunition depot to the base does not exceed ten minutes..."….

Liandao has long been hollowed out. To the outside world, this may be just a rumor, but as the commander of the Army and Navy, Shen Honglie knows that this is by no means a rumor. In the past two years, Shen Honglie knew that this is not a rumor.

On this small island, more than 60,000 labor corps and marine engineers worked day and night to improve this fortress island, forming an overall layout of one fortress, one port, one school, and one battalion on its surface.

This island with a coastline of only 1,766 kilometers has more than 200 kilometers of fortress passages underground. In some areas, the underground fortresses are multi-layered. Almost all warehouses, ammunition depots, and oil depots are built underground. According to the

The original design concept. Even if the island is completely blocked, it can maintain it for more than five years relying on its own reserves. Although the possibility of the island being besieged is unlikely, as the gateway to Lianyungang, various possibilities must be considered. Even the most

Impossible things also need to be considered. With this island as a support, no enemy, whether external or internal, can capture Lianyungang.

"...Of course, the most important thing is the dock-type submarine base, because this is the Navy's first submarine fortification. So in the overall design of the fortification, we considered two possibilities..."

When he was about to enter the dock base, Shen Honglie added something more.

"The dock itself can be built in two ways - "dry" and "wet". The former can drain the internal seawater so that the submarine can be repaired and maintained. Its size varies. Usually the foundation surface of this dock reaches the storage area.

The height between the water levels behind the water is 10 meters. In addition, the dock also retains a ceiling of a certain height to accommodate cranes. This kind of crane is often used to completely dismantle the periscope on the submarine for repair, with a lifting capacity of up to 30 tons. Each

Each dock has at least one water pump with a pumping capacity of 3,000 cubic meters, in addition to an auxiliary pump with a pumping capacity of 380 cubic meters, and sometimes more. These pumps are installed between every two docks.

The water pump has the ability to drain all seawater in the dock within 3 hours. In the Sujiawan base, docks 2 and 4 are dry docks, which are characterized by full maintenance capabilities, while docks 1, 3, and 5 are dry docks.

Compared with dry docks, the construction cost of wet docks is relatively low, but according to the current plan, setting up a five-door submarine base with a capacity of 12 boats will only require two dry docks at most to ensure the base's

Wartime maintenance and upkeep of internal submarines..."

Finally, he entered the dock, and the moment he entered the dock, Li Zicheng seemed to have found some familiar pictures. They were pictures from the military game he played many years ago, including the submarine fortifications in Hunting and Submarine and many others.

The submarine fortifications in this game are so similar to the docks you see in front of you. What is the similarity? They are basically carved from the same mold. After all, the pictures in the game come from the ruins of German submarine fortifications during World War II, and their

The drawings come from Germany during World War II, and the submarine cave bases designed and built by Germany during World War II are considered to be strong and durable. Even in the 21st century, many of these bases are still used by some countries. Among online games

The ultimate scoundrel read in full.

"...Because the Sujiawan base faces the sea, in order to avoid being exposed to war artillery, in addition to strengthening the base as much as possible, the interior of the dock is also reinforced with a large number of armored steel plates, plus a layer of reinforced concrete, the thickness of which can reach 15 meters.

, used to protect important locations in the dock, such as gates. In addition to traditional shelling, and considering the impact of possible future air attacks, the top of the submarine cave has also been effectively reinforced.

The roof of the warehouse can completely resist the attack of aerial bombs..."

After a report, Li Zicheng looked at this huge and spectacular submarine cave base. Although he was extremely satisfied, he still had some shortcomings. After all, these bases could not really be used in the future.

"Well, Cheng Jun, look back, you can organize the technical staff and consider digging a cave base directly into the mountain. You can try it in Qingdao!"

In later generations, submarine bases were often built into mountains. Compared to such man-made bases, bases with mountains as shields may be stronger and more concealed.

"You can consider Qingdao, after all..."

Looking at Shen Honglie, Li Zicheng said in a serious tone.

"In the future, I estimate that the base will be used much more frequently than this one! After all, the neighbor to the east..."

Shaking his head, Li Zicheng sighed again.
