Qinggang Xingyue Bay is majestic and atmospheric, with a unique wheel-type community layout;

The Smoky City Star Moon Bay is prosperous and has the largest horse racing venue in China and even the world.

Weicheng Xingyue Bay has a fragrance that spreads for ten miles, with a super food city and the most complete future plans.

There are only Zhaocheng on the south side and Yingshi on the north side at the mouth of the Yellow River on the north side.

Ge Xiaotian ate watermelon and watched the big guys' battle with Longtian Technology as a chessboard, while sighing at the enemy's strength, he recalled his own industry, and then went to Jiaozhou Bay where engineering machinery gathered.

In another time and space, the Jiaozhou Bay Cross-Sea Bridge is 36.48km long, which is 10km longer than the Incheon Bridge that Tiancheng is about to be built.

Unfortunately, g22, which is the Qinglan Expressway connecting the Jiaozhou Bay Cross-Sea Bridge, has not been planned yet. Even if Tiancheng wants to undertake it, it is just a imagination now.

What's more, the construction of the Jiaozhou Bay Cross-Sea Bridge has another deep meaning: training for the Bohai Bridge.

In this way, Tiancheng will definitely not be able to rob the national font.

However, there are many obstacles and troubles encountered across the Bohai Bridge, one is national defense, the second is funding, and the third is earthquake. The relevant departments have been arguing for a long time and have turned to the undersea tunnel of Yancheng-Liancheng.

The tunnel is 123 kilometers long and requires at least 200 billion yuan. Unfortunately, the funds were not collected until the crossing...

This matter needs to be discussed for a long time, and then make money first.

……………………

Today, January 4th.

The wind is gentle and the sea is not rippling.

At 8 o'clock in the morning, in Jiaozhou Bay.

Tiancheng's foreign technology seminar, the second class is about to begin.

The first class?

When introducing Dongshan Jianda University, Dongshan Art College, and Quyi Academy, before the idiom competition, Ge Xiaotian gave a very one-sided online infrastructure course that does not involve technology.

At that time, no one joined Jinxiuchuan, so he would definitely not talk in depth.

But today is different, it is all real and new technologies that are at the forefront of the infrastructure of the parent star.

At the scene, the young and white-headed leader led the young followers to look forward to it, and the temporary stands were filled with employees.

Online attendees include: Dongshan Jianda Bridge Department, Tiancheng Technical Technical College cross-sea engineering major, and many colleagues...

In 2001, although China's infrastructure rose, most of its technologies were unknown and were regarded as the treasure of the family by national construction workers.

Even in college majors, only Tiancheng Vocational Technical College has opened cross-sea engineering subjects.

For example, some construction companies with ambitious goals and ambitions are happy to spend money to listen to the lecture this time.

"We welcome leaders at all levels, seniors, and seniors from all walks of life to participate in this Tiancheng Open Class."

"Today, we mainly talk about cross-sea engineering, with a total of 36 lessons. I am responsible for the early stage, Professor Hu is responsible for the mid-stage, and General Liang is responsible for the late stage. The entire process follows the progress of the Incheon Bridge project and finishes it in half a year."

"Let's get to the point."

"In the past twenty years, construction technology has been innovated several times, the material composition has been changing, the design plan has been changing, the construction process has been changing, and people's thinking has also changed."

"A variety of heavy machinery emerges one after another, countless production tools are dazzling, and the incomprehensible structural diagrams are getting thicker and thicker. The valuable works left by many predecessors in the industry have gradually become references, and have even been overthrown and abandoned... This is the power of the times."

"Studying is a difficult process. Most people choose majors not because of hobbies, but because of their good jobs. No one wants to work hard for three or five years, but after graduation, they find that the knowledge they have learned has been eliminated by the times."

"There is a saying in Tiancheng Corporate Culture Manual: Theory always harms people, practice is the truth, and innovation can win in the future."

"If you want to keep yourself at the forefront forever, the most important thing is not to talk about things on paper, but to seek truth and explore!"

"For this reason, Tiancheng will make 60% of the profit every month, invest in the research on new building materials and new machinery, and even spend a lot of money to learn the most advanced design concepts overseas and introduce the most advanced heavy construction machinery."

"That is why today's success is achieved."

Ge Xiaotian adjusted the new generation of SG equipment connected to optical fibers and faced the camera to the mechanical group gathered in the sea.

"We will learn about the equipment later. Now let's talk about what you need to pay attention to in the early stage of deep-sea construction."

"First of all, life jackets must be worn at sea."

Ge Xiaotian lifted up an orange-red vest, "This is a life jacket developed and designed by Tiancheng, with a luminous function and mainly buoyant materials. It is capable overall, durable and wear-resistant, and very light, ensuring that the user can expose his head out of the water even if he is unconscious. In addition, it has a multi-functional pocket that does not hinder construction and can keep warm. The original price is 68, and now it only costs twenty red bills to get it!"

“???”

Many entrepreneurs suddenly felt strange...

"Secondly, the necessary location search and rescue device at sea."

Ge Xiaotian picked up a wristband similar to a watch, "This is a positioning equipment with watch functions commissioned by Tiancheng. It is waterproof, fall-proof, riot-proof and static, and is light and easy to wear. It can not only allow users to cultivate the concept of time, but also find the missing person immediately after an accident. The original price is 18, but now it only costs fifty red bills!"

Many entrepreneurs: "…"

"The other one is that emergency high-energy compressed biscuits and aerospace-grade toothpaste food nutrient solution, combined with the two, can provide enough energy for construction workers in natural disasters. The original price is 28, and now each serving only requires five red bills!"

Many entrepreneurs: "…"

"I'm not selling. Mr. Cai, please don't look at me like this. The sea construction environment is really harsh, the climate is changing, the points are numerous, the lines are long, the personnel are scattered, the equipment is large, the traffic is inconvenient, and the range of activities is limited. It's very dangerous! With these three magical tools, the danger coefficient can be reduced to a minimum."

"Of course, we cannot pin our hopes on items, and we must also manage them well."

"According to the category, Tiancheng lists construction specifications for environments such as equipment reinforcement, house reinforcement, steel pipe pile sandbag maintenance, high tide and low tide avoiding beaches, etc. It will be sent to everyone later in the form of a promotional poster. Please use the smart card or SG device to download the poster. The poster is beautifully typed and matched with pictures and texts, and can be understood even if you can't read. It also has waterproof and moisture-proof and eye-catching warning functions. The original price is 68. Now each one only needs ten red bills, and it will never have the Tiancheng enterprise icon!"

Many entrepreneurs: "…"

When did the Huaxia Sanjian leader who entered the multimedia room, he typed in the chat box: "Can you start?"

"Start start, start right away! However, before starting, we will talk about the class issues."

"The first class is indeed an open class. Everyone has seen what technology and equipment Tiancheng has. All the contents of the follow-up lectures follow the progress of the project, which means that the next 35 class hours will be charged!"

"Except for Jinxiuchuan students, each student has 50,000 red bills per class, with a package price of 1.6 million yuan, and there are also fine collections of fine products on the construction site. All of them are not passed down, and they are worth the money!"

Many entrepreneurs: "…"

"Okay, the students stay, seniors from outside, please go out of the group."

“…”

Wait for the administrator to kick out the non-student ID, Ge Xiaotian operates the SG notebook and displays a set of PPT.

"We need to choose the corresponding plan based on the drawing design and surrounding environment."

"I won't talk about the chlorine content of seawater, earthquake rating, tide changes, etc. Today I will learn from myself after class."

"If you want to carry out cross-sea projects, you first need a 'operation platform' to facilitate our personnel to move around and transport building materials."

"We can use the 'construction trestle to turn water into shore', or use the 'set of floating platforms in the water', or the 'tugboat and floating crane construction multiple points."

"What is a construction trestle? Looking at the picture, it is composed of bridge piers and beam span structures, which can directly serve construction."

"However, the trestle is a long time. At sea, it is composed of a beret, also known as the prefabricated highway steel bridge. It is our main operating platform. It undertakes the construction raw materials and semi-finished products of this project to drive and pass through, and it takes a long time to use it."

"In the offshore construction specifications that have just been issued, there are some protection measures for it, such as when tides come, stone throwing and sand throwing bags are taken to avoid the trestle being washed away, so as to ensure the overall stability of the product platform and the depth of the steel pipe piles. For example, steel pipes are connected in parallel around the trestle, and the pile top steel beams and steel pipe piles are welded to form an integral steel frame for flood control and typhoons."

"Everyone just needs to know its functions, not to understand them in depth, because we have an engineering island with a 'floating platform' structure."

"The function of the engineering island is exactly the same as the trestle, but it can be moved, has its own lifting and drilling equipment, or it integrates the functions of sea transportation and work platform."

Ge Xiaotian switched the picture, "The engineering island and transport ships, floating gondolas, other transportation tools, combined with the "floating islands" of the logistics department, form an operational area, that is, our construction environment, turning the sea into 'land'."

"In this way, we can carry out the next construction link, based on the construction drawings, structural drawings, design drawings, build cast piles, and prefabricated T-shaped bridges,"

"The thousand-ton prefabricated t-beam is under the responsibility of logistics, while our front-line personnel are responsible for casting piles."

"The technology of deep-sea cast-injected piles is that due to the characteristics of concrete, it is impossible to directly construct in water. Concrete that can last for 50 years on land may only last for one or two years in the sea. Our goal is to isolate the water from the pile foundation, ensure the quality of the project, and allow the cross-sea bridge to last for a hundred years!"

"When we build deep-sea piles, there are many plans and when the water is not deep, we need to build an island cofferdam."

"It is to build a small island with sacks filled with soil and sand and gravel. On the outside are sealed steel hanging boxes or steel sheet piles. After filling, the mud and sand are hollowed out and the sea water is continuously pumped away with a water pump, which forms a cofferdam. In the cofferdam, the pile foundation and piers can be constructed like the ground. If the water is too deep, it is impossible to cofferdam, and the pile foundation is used. The pile driving boat drives multiple steel pipes to the holding layer, with a depth ranging from 70 to 90 meters. After the drainage is completed, reinforced concrete is added to the inside, and the pile foundation is firmly fixed in the water so that the bearing platform and piers can be built on it."

"In the deep sea areas, we need to use drilling rigs and drill bits that match the terrain."

"The drilling operation platform, which has been mentioned before, adopts engineering islands."

"Making steel cages and steel casings are also on the engineering island."

"The next step is to bury the steel casing and the drilling rigs needed for the operation..."

"Because we are building deep-sea piles with large hole diameters, complex geology, thick cover layer, and the casing sinks to reach the rock layer, and the hole formation time is long, some effective measures should be taken to avoid hole collapse during the drilling process."

Ge Xiaotian opens the simulator.

"For example, when drilling, the tide outside the hole affects the head inside the hole, and the head can be controlled by using internal and external water pumps..."

"For example, appropriately control the speed of the inlet, and repeatedly throw and add stones when drilling to the bottom of the cartridge to strengthen the arm guard..."

"For example, when using seabed silt as drilling mud, the characteristics of this mud are not dispersed and have high viscosity, which can effectively avoid hole collapse..."

"The latter part is Qing Kong."

"The purpose of cleaning holes is to replace the original mud, change the mud performance in the holes and remove the sediment at the bottom of the hole..."

"It should be noted that when changing the slurry and clearing the holes, the water head needs to be kept to prevent the holes from collapse."

"The next step is to install a steel cage and clean the holes twice..."

Ge Xiaotian switched to the ‘mud positive cycle diagram’ and ‘mud reverse cycle diagram’ and changed to ‘filled underwater concrete’.
