Building madman

Qinggang Xingyue Bay is majestic and majestic, with a unique layout of a wheeled community;

Yancheng Xingyue Bay is prosperous and has the largest horse racing venue in China and even the world.

Weicheng Xingyue Bay is fragrant for ten miles, with a super gourmet city and the most complete future plan.

In the coastal cities of Dongshan, only Zhaocheng on the south side and Yingshi on the north side at the mouth of the Yellow River did not go.

After eating watermelon, Ge Xiaotian remotely watched the big boss fight with Longtian Technology as the chessboard, while lamenting the strength of the enemy, while reminiscing about his own industry, he then came to Jiaozhou Bay where construction machinery gathered.

In another time and space, the Jiaozhou Bay Bridge is 36.48km long, which is 10km longer than the Incheon Bridge that Tiancheng will build.

It is a pity that G22, which is the Qinglan Expressway connecting the Jiaozhou Bay Bridge, has not yet been planned. Even if Tiancheng wants to take it, it is just a conjecture.

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

In this way, Tiancheng must not be able to grab the national brand name.

However, the Cross-Bohai Bridge encountered many obstacles and troubles, one is national defense, the other is funding, and the third is earthquake. The relevant departments have been demonstrating for a long time and turned to the Yancheng-Liancheng subsea tunnel.

The tunnel is 123 kilometers long and requires at least 200 billion yuan. It is a pity that funds were not collected until it passed through...

This matter needs to be considered in the long term, first make money.

………………

Today, January 4th.

The wind is sunny and the sea does not rise.

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

Tiancheng's foreign technology seminar, the second lecture will start soon.

First class?

When introducing Dongshan Jianda, Dongshan Art College, and the Academy of Fine Arts, before the Idiom Solitaire competition, Ge Xiaotian gave a very one-sided, technology-free online infrastructure course.

At that time, no one had joined Jinxiuchuan, so he would certainly not speak in depth.

Today is different, it's all real, and it's a new technology at the forefront of the parent star infrastructure.

At the scene, the big leader Shaobaitou led the small attendants eagerly waiting, and the temporary stands were filled with Tiancheng employees.

Online lecturers include: Dongshan Jianda Bridge Department, Tiancheng Technical Secondary School Cross-sea Engineering, and many colleagues...

In 2001, despite the rise of Huaxia Infrastructure, most of the technologies belonged to unspoken secrets, and were regarded as the treasures of the town by National Construction Engineering.

Even in terms of majors in colleges and universities, only Tiancheng Vocational School offers cross-sea engineering subjects.

Like some construction companies with ambitious goals and ambitions, this time it can be said that they are willing to spend money to listen to the lecture.

"Welcome leaders at all levels, seniors, seniors and students from all walks of life to participate in this Tiancheng public class."

"Today's lesson, we mainly talk about cross-sea engineering, a total of 36 hours, I am in charge of the early stage, Professor Hu is in charge of the middle stage, and Chief Engineer Liang is in charge of the later stage. The whole process will follow the progress of the Incheon Bridge project and will be finished in half a year."

"Stop gossip, let's get to the point."

"In the past two decades, there have been several innovations in construction technology, material composition is changing, design schemes are changing, construction processes are changing, and people's thinking is changing."

"Various types of heavy machinery emerge in endlessly, countless production tools are dazzling, and incomprehensible structural drawings are getting thicker and thicker. The valuable works left by many industry predecessors have gradually become reference, and even been overthrown and abandoned... This is the era. the power of."

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

"There is a saying in the Tiancheng corporate culture manual: Theory always harms others, practice is truth, innovation can win the future."

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

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

"And because of this, we have today's Tiancheng."

Ge Xiaotian adjusted the new generation of SG equipment connected to the optical fiber, facing the camera to the group of machinery gathered in the sea.

"Equipment, we will learn about it later. Now let's talk about what we 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 mentioned an orange-red vest, "This is a life jacket developed and designed by Tiancheng. It has a luminous function and is mainly made of buoyant materials. The overall is capable, durable and wear-resistant, and very lightweight, ensuring that the user can expose his head even if he is unconscious. Water surface. In addition, it has multifunctional pockets, which does not interfere with construction and can keep warm. The original price is 68, but now it can be taken with only 20 red bills!"

"???"

Many entrepreneurs suddenly feel strange...

"Secondly, a positioning search and rescue instrument is necessary at sea."

Ge Xiaotian picked up a wristband similar to a wristwatch, "This is a positioning device with watch function commissioned by Tiancheng Longtian, which is waterproof, anti-drop, anti-riot, anti-static, light and easy to wear, and can not only cultivate the concept of time. , And after his accident, the missing person can be found in the first time through the positioning device. The original price was 180, but now it only costs fifty red notes!"

Many entrepreneurs: "..."

"Another one is that emergency high-energy compressed biscuits and aerospace-grade toothpaste-type food and nutrient solution, together, can provide enough energy for construction workers in natural disasters. The original price is 28. Now each serving only needs Five red notes!"

Many entrepreneurs: "..."

"I'm not selling, Mr. Cai, please don't look at me like that. It is really dangerous because of the harsh offshore construction environment, variable weather, long lines, scattered personnel, many equipment, inconvenient transportation, and limited range of activities! With these three artifacts, the risk factor can be reduced to a minimum."

"Of course, we can't put our hopes on the goods, and management must be in place."

"According to the category, Tiancheng listed construction specifications for typhoons, thunderstorms, tornadoes, tides, heavy fog and other environments, such as equipment reinforcement, house reinforcement, steel pipe pile sandbag maintenance, high tide and low tide avoiding the beach, etc. Later, it will be sent to you in the form of a promotional poster. Please download it with a smart card or SG device. The poster is beautifully typeset, with pictures and texts, and can be understood even if you don’t read. It also has the functions of waterproof, moisture-proof and eye-catching warning. The original price was sixty-eight, and now only ten red notes are needed for each one, without the Tiancheng corporate icon!"

Many entrepreneurs: "..."

The leader of China Sanjian, who entered the multimedia room at some unknown time, typed in the chat box and said: "Can we still start?"

"Start, start now! But before we start, let's talk about class issues."

"The first class is indeed an open class. Everyone has seen what technology and equipment Tiancheng has, and all subsequent lectures follow the progress of the project. In other words, there will be charges for the subsequent 35 class hours!"

"Except for the Jinxiuchuan students, each student has 50,000 red notes per class hour, with a package price of 1,600,000 yuan. There is also a collection of exquisite collections from the construction site. It is all secrets that are not passed on, and the value is excellent!"

Many entrepreneurs: "..."

"Well, the students stay, the seniors and peers outside, leave the group."

"..."

After the administrator kicked out the non-student ID, Ge Xiaotian operated the SG notebook and displayed a set of PPT.

"For cross-sea projects, we must choose the corresponding plan based on the drawing design and the surrounding environment."

"Such as the chlorine content of seawater, earthquake levels, tidal changes, etc., I will not go into details today. I will learn by myself after class."

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

"We can use'construction trestle bridge to turn water into shore', we can also use'floating platform in water', or'multi-point construction by tugboat and floating crane'."

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

"However, the trestle bridge is more than a few minutes away. At sea, it is constructed by Bailey. It is also known as the prefabricated highway steel bridge. It is our main operating platform. long."

"In the offshore construction specifications just issued, there are some protective measures for it, such as the approach of tides, the use of stone dumping, sandbags, etc., to prevent the trestle bridge from being washed, so as to ensure the overall stability of the product platform and the entry of the steel pipe piles into the soil. Depth. For example, steel pipes are connected in parallel around the trestle bridge, and the pile-top steel beams and steel pipe piles are welded and consolidated to form an integral steel frame for flood resistance and typhoon."

"You only need to know its functions, and don't have to understand it deeply, because we have an engineering island with a'floating platform' structure."

"The function of the engineering island is exactly the same as that of the trestle, but it can be moved and has its own lifting and punching equipment, or in other words, it integrates the two functions of marine transportation and work platform."

Ge Xiaotian switched pictures, "The engineering island, transport ships, floating cranes, and other means of transportation, combined with the "floating island" of the logistics office, form a working area, which is our construction environment, turning the sea into a "land".

"In this way, we can proceed to the next construction stage, according to construction drawings, structural drawings, and design drawings to build cast-in-place piles and prefabricated T-shaped bridges,"

"The 1,000-ton precast T-beam is responsible for the logistics, and our frontline personnel are responsible for the cast-in-place pile."

"The technology of deep-sea cast-in-place piles is basically that because of the characteristics of concrete, it cannot be directly constructed in water, and concrete that can last for 50 years on land may only last for one or two years in the sea. Our goal is to combine water with The pile foundation is isolated to ensure the quality of the project and let the cross-sea bridge last for a hundred years!"

"There are many options for building deep-sea piles. When the water is not deep, we need to build an island cofferdam."

"It is to build a small island with sack full of soil and sand, with a closed steel box or steel sheet pile on the outside. After the filling is completed, the sand is hollowed out, and the sea water is continuously pumped away by a water pump. For cofferdams, pile foundations and bridge piers can be constructed like the ground in the cofferdam. If the water is too deep and the cofferdam is impossible, the pile foundation method must be used. The pile driving ship drives multiple steel pipes to the bearing layer The depth ranges from 70 to 90 meters. After the drainage is completed, reinforced concrete is poured into it, and the pile foundation is firmly fixed in the water, so that the platform and pier can be built on it."

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

"The drilling platform, as mentioned before, uses an engineering island."

"Making steel cages and steel protective tubes are also in the engineering island."

"The next step is to bury the steel casing and the drilling rig required for the burying operation..."

"Because we are building deep-sea piles with large diameters, complex geology, thick overburden, the sinking of the protective tube cannot reach the rock formation, and the hole formation time is long. During the drilling process, some effective measures should be taken to avoid hole collapse."

Ge Xiaotian turned on the simulator.

"For example, during drilling, the tide fluctuation outside the hole affects the water head inside the hole, and the internal and external water pumps can be used to control the water head..."

"For example, properly control the speed of the footage, when drilling to the bottom of the protective tube, repeatedly throwing stones and strengthening the arm guard..."

"For example, using submarine mud as drilling mud at the same time, this mud is characterized by non-dispersion and high viscosity, which can effectively avoid hole collapse..."

"The latter link is clearing holes."

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

"It should be noted that when the slurry is changed and the hole is cleared, the water head needs to be maintained to prevent the hole from collapsing."

"The next step is to install the steel cage and secondly clear the holes..."

Ge Xiaotian switched the'Mud Positive Circulation Diagram' and the'Mud Reverse Circulation Diagram', and replaced it with'Underwater Concrete Pouring'.

"After the second hole cleaning is completed, the underwater concrete should be poured immediately, and the amount and time of pouring should be calculated according to the specifications of the pile. The method of pumping concrete should be used, and the slump should be controlled within 12cm-18cm."

"Because of the long pouring time, we can mix our Tiancheng's self-produced college retarding and water-reducing agent into the concrete to slow down the initial setting time of the concrete and avoid the blockage of the pump pipes and conduits..."

"The infusion period shall not be interrupted and shall be carried out in rapid succession..."

"In addition, our construction belongs to winter, and we need to consider the issue of freezing..."

"The other is grouting at the bottom of the pile to increase the bearing capacity of the bottom of the pile and reduce settlement..."

Ge Xiaotian finished the "bored pile construction technology" in one breath and released the important test points of this class.

"Of course, the above are just the simplest construction schemes for Tiancheng, and perhaps others have adopted it. In the third class, we will list Tiancheng's own unique subsea construction technology, and we are here today."

Ge Xiaotian distributed the encrypted courseware to students and employees.

These things, put in the future, almost every construction company will have, but in 2001, plus detailed parameters and technical guidance, it is very precious.

For example, if an entrepreneur who was kicked out wants to understand deep-sea construction, he doesn't have to learn or teach it.

Pay the tuition!

One class is 50,000 yuan, 36 class hours, the first lesson is free, then one person is 1.6 million, ten people is 16 million, and 100 people is one hundred and sixty million...

This is all money!

As for the other party to learn, will they grab their own projects...

Do you have equipment?Do you have funds?

And, when they learn, Tiancheng's technology will iterate.

As he said before, the times are advancing, and if you don't research and develop yourself, you will be eliminated sooner or later.

Ge Xiaotian turns off the camera and lights a cigarette beautifully...

At this time, Director Sun, who was staying in Nan Bangzi, called.

"Boss, it's done!"

"So soon? Isn't the bidding finished tomorrow, and the result will be announced the day after tomorrow?"

"France quoted 3.5 billion Franklin for completion in seven years, and Nanbangzi required five years, but it would definitely not work. The third brother quoted 1.3 billion Franklin, which was built in four and a half years, but Nanbang did not dare to use it. Wadao offered 1.6 billion Franklin. Built in five years, the design is very good, and it is also our main competitor."

Director Sun paused for a while, "However, Wadao Construction was kicked out by the Nanbangzi local construction company of the United England. It is said that Nanbangzi Local Construction has learned about the bids of various enterprises through contacts and believes that Wadao is the most competitive. Something happened secretly. As for us... 10.3 billion, it is estimated that they think we will definitely be eliminated."

"How did the local construction workers who joined with England get eliminated?"

"Reported by KS."

"This teammate... is awesome! Ready to start!"

Ge Xiaotian put down his mobile phone, and just about to close his SG notebook, Da Mao called.

This is rare.

"what happened?"

"Boss, the chairman of Huaxia Petroleum Refining & Chemical, wants to invite you to meet."

"Ok?"

Ge Xiaotian narrowed his eyes, "Tell him, if you don't have time, you can come to me at sea."
