Build Madness

As the saying goes, there is a dictatorship in the art industry.

Mr. Yu worked as a porter in an oil refinery, worked in foreign business, worked in a front-line workshop, worked in the logistics and statistics office, and worked as the general manager of Petroleum in Guangzhou...

After a set of procedures, don't look at Dongshan who is taking the lead now, but in terms of oil, he is better than his family. Like Chen Dong, he is at best a half-way monk in front of him.

If Ge Xiaotian refuses to ask for the Buddha like Mr. Yu, refuses old oil like old money, and refuses to dig for the old team of Guangzhou Petrochemical, it is simply ashamed of the Tiancheng corporate culture shaped by Xiao Huang.

However, Mr. Yu's promise to help is tantamount to standing on the opposite side of Mr. Chen.

In order to have a buffer period, or to allow enough preparation time for his family, Ge Xiaotian finished counting Tiancheng's domestic fuel storage, and did not immediately go to the capital to visit CNOOC executives, but suspended the second phase of the domestic Xingyue Bay project and started the third session. class.

……………

As early as the afternoon of the first day of bid negotiation, Tiancheng employees had completed the entry and exit procedures, followed the equipment to the front line, and dispersed to the 21 points assisted by the GLONASS system.

The 20,000 employees were scattered to 21 o'clock, and it was hard to see how spectacular it was, but dozens of machines nearly 100 meters high suddenly appeared in the vast sea...

This feeling is far more shocking than the land infrastructure group.

In fact, there is a huge problem with multi-point construction, that is, there will be errors when the viaducts are connected to each other.

If it were an ordinary construction company, they would definitely not dare to play like this. If there is a deviation in a certain interval, it is estimated that the entire project will deviate from the design requirements.

Therefore, most enterprises will choose a construction plan that goes forward at both ends, butts in the middle, or goes all the way to the end.

However, Tian Cheng has a system.

First rely on the GLONASS positioning system, let the strong man arrive at the construction area by boat, and then open the market drawing to cover the explored system map.

Then according to the construction plan, contact the strong man by phone to fine-tune their respective positions until they align with the points marked on the construction drawing that have been enlarged countless times...

From now on, the location of the strong man in reality will be one deep sea pile after another.

This method is more accurate than satellite positioning, and the error does not exceed the diameter of the red dot representing a strong man, which is about 0.1mm.

Let's call it Tiancheng's unique method of 'pull the thread'.

Now a week has passed, and there are already six floating islands in the 21 construction areas distributed in an arc shape in the Incheon waters.

That is to rely on six system A-type ships to build an offshore platform for building various system buildings.

The whole is divided into staff accommodation area and building materials storage area. Each floating area radiates three construction areas, and the extra three are on land, without floating islands.

January 13th.

At eight o'clock in the morning, the sea fog is hazy.

Floating Island No. 1.

Ge Xiaotian was wearing a life jacket, a search and rescue instrument, a nutrient solution in his waist, and equipment similar to a Steadicam camera kit on his shoulders. Facing the howling wind, he walked towards the construction site.

On the edge of the floating island, nearly a thousand Tiancheng employees are busy.

According to the requirements of the contract, 2,000 foreign employees received from Incheon are studying hard on holding steel bars and pouring cement in the building material storage area of ​​Fudao Island.

This is an advanced technology unique to Tiancheng.

Students, in the last class we were familiar with the main process of deep-sea construction and the precautions for each link, so today we will refine these steps so that everyone can understand more intuitively and clearly how a cross-sea bridge is built .”

The sea area we are in now is 12 meters shallowest and 16 meters deep...

In the past 30 years, the tidal rise has averaged ±4 meters, with an error of no more than 10 centimeters. The wind speed at the center of the bottom layer of the strongest tropical storm is 25 m/s, and the wind speed of the strongest typhoon is 45 m/s. The super typhoon has not yet occurred...

The trestle bridge I talked about in the last class is the floating island under my feet, which is connected to the logistics of Weicheng University by transport ships...

Our staff has installed the equipment...

Ge Xiaotian stepped into the engineering island that had been docked with the floating island, and climbed up the clamp-type robotic arm workshop built in the town center.

Before, he originally thought that this device was a super large pliers, which were used to clamp huge goods for easy loading and unloading, but after careful study, he found that this thing turned out to be a super vibrating pile hammer.

What do you mean?

It is through the hoist at the top (similar to a tower crane that retracts and unwinds steel cables), that the claw-shaped pliers at the top of the mechanical arm and the round iron bumps on their upper parts can be put into the deep sea like a chain hammer.

Well, just put it in, it doesn't make much sense.

But if the pliers can clamp the wall of a hollow steel casing with a length of eight meters, a diameter of 1.5 meters, and a wall thickness of 10 mm, relying on tens of meters, or even hundreds of meters of steel cables, to vertically penetrate the seabed...

Then, the huge iron lump on the upper part of the claw-shaped pliers, driven by electricity, can generate hundreds or even thousands of impacts per second, forming a continuous force, and then knock the hollow steel casing into place like a nail. Into the sea...

Then, the top is connected to the second section, the third section, and the fourth section of the hollow steel casing in turn, and continue to fight...

When the construction requirements are met, the remaining steel casings are spliced ​​until they are exposed to the sea...

Finally, drain the water, mud, broken rock, etc. in the casing, and inject the steel cage and underwater anti-corrosion cement...

The first link of the deep-sea foundation pile is done in this way.

It is a bit like the immersed tube well construction technology on land, but in the deep sea, without this equipment, in this era, even ten years later, it can only be played in the shallow sea.

Now that there is a disguised engineering island in the center of the town, Tiancheng can definitely undertake projects in deeper sea areas, including oil exploration platforms.

Ge Xiaotian was operating the robotic arm on the spot while explaining on the spot. Before he knew it, a day passed...

And his third class is coming to an end.

The engineering class is like this, listening to it in a fog, taking a look, taking a look, touching it, practicing it...

Damn, it's so difficult!

Mainly, it also involves the production of steel casings, the butt jointing process of steel casings, the automatic alignment of vibratory hammers, and whether the steel casings meet the construction standards (to avoid being knocked crookedly like nails)...

As well as underwater cement composition, anti-corrosion process, performance indicators...

Matters needing attention in the transportation and installation of steel cages.

Since Tiancheng only has one engineering island and two pincer-type mechanical arms, if it wants to meet the construction requirements, it must have 8-10 mechanical operators for the two positions to carry out piling around the clock.

Fortunately, after upgrading the four-level system, sailors and helmsmen who have been transferred from strong men can continue to transfer jobs and become marine mechanics.

After talking about this, the students who have listened to and watched for a day went back to review.

The next day, January 14th.

Ge Xiaotian struck while the iron was hot and started the fourth class.

The reason for being so anxious is because... the Spring Festival is coming, and the group has a three-day holiday.

Therefore, he was going to spend six days to complete the rest of the course.

It's just strange that none of the bosses who attended the class before bought the course.

I really thought I was running a game. Buy it early and enjoy it early, buy it later and get a discount!

Before Ge Xiaotian started the fourth class, he set the unit price of the video files on the LT-store to 100,000, and the full set would cost 3.5 million!

Another standard: big promotion during the Spring Festival, the price will increase after the year!

And upload parameters and photos of numerous devices.

If I want to make money, I not only have to buy, but also rent my machinery!

Students, today we will talk about the design and construction of viaducts.

It sounds like it may overlap with the courses of Professor Hu or Chief Engineer Liang, but this is linked to the pier, and the level and function of our teaching are different.

Since the design of the lower structure of the bridge starts immediately, the design of the upper structure is limited by the determined strength of the lower structure. It is necessary to accurately judge the margin reserved for the lower structure. If the margin is large, the degree of freedom in the design of the upper structure will be greater. Tends to increase costs, and accurate forecasting of margins is important when using rapid construction methods...”

The viaducts on the entire line adopt pc beams with a span of 50m uniformly, with 5 spans and one connection...

It was designed this way because the use of uniform spans in the straight sections reduces the design effort and construction time.

The height of the box girder is 3m, the strength of the concrete is 45MPa, and the entire span is used for construction...

The substructure is a gantry structure rigidly connected to the cast-in-place pile foundation and the bridge pier, and the substructure of the sloped section connected to the approach bridge is a cast-in-place pile foundation and circular solid pier...

Having said this, Ge Xiaotian came to the prefabricated site of the floating island.

The prefabricated factory building is 25m high, 30m wide, and 210m long...

The prefabricated girder of the viaduct is 50m long and weighs 1350t...

It takes 1 day to bind the steel bars of prefabricated beams, and the concrete is supplied by the concrete factory adjacent to the prefabrication field. After the concrete is poured, it is cured for 17 hours with steam at a maximum temperature of 60°C to reach early strength, so as to shorten the curing time. Therefore, Tiancheng only needs 2D can make a prefabricated beam!

And how many factories like this do we have...

Ge Xiaotian pointed the camera at the two nearby floating islands in the distance, There are 12 on the sea, and there are two on each of the six floating islands. There are also 50 such steam workshops on both sides of Weicheng and Incheon, ensuring that bridge erecting machines and floating When the gondola is in place, it will be supplied as soon as possible.”

Next, let's look at the production method...

Before you know it, another day passes by...

In the next few days, Ge Xiaotian will discuss the design of the approach bridge, the construction of the approach bridge, the cast-in-situ piles of the main bridge of the cable-stayed bridge, and the foundation piles of the tower of the cable-stayed bridge...

And the corresponding construction techniques, such as hoisting the cap formwork, installing stay cables and shock absorbers, processing expansion joints, installing expansion joint monitoring systems, etc., will be explained one by one, and even hands-on operations.

Follow-up, such as 'large segment construction and construction accuracy control', 'use method of 6000t floating crane designed to greatly shorten the construction period', 'key points of cantilever construction of main span steel box girder segment'...all are Professor Hu and Mr. Liang's courses.

Such cramming definitely needs the help of the system university, which is why the courses are set up in the multimedia teaching hall.

When the deep-sea piling process is halfway through, the land and beach projects have already begun to lift beams.

Taking this opportunity, the Department of Civil Engineering of Dongshan University of Construction and the Department of Cross-sea Engineering of Tiancheng Technical Secondary School collectively applied for the exchange students of Nanbangzi Incheon University, and then arrived at the construction site to start the final practice exam of the first semester...

Tian Cheng made such a big commotion, which already caused an uproar in the Chinese education circle.

Professor Hu even said that if there were no enrollment restrictions, Dongshan Kent University would recruit at least 50,000 new students next year!

You know, Tian Cheng's treatment in China has always been extremely high, while overseas...

Even students can get a subsidy of 100 red notes a day!

The reporter who heard the news came to block Ge Xiaotian who was about to return to China before the Spring Festival, that is, on January 21st and the 27th day of the twelfth lunar month.

Mr. Ge, using the internship as an excuse, are you worried about being punished for recruiting child labor?

Mr. Ge, may I ask those beautiful female students, why do they wear stockings and short skirts in winter?

Mr. Ge, there is a rich woman who bid for your dinner and spent more than one million yuan. After more than half a year, why do you keep missing appointments? Are you guilty?

Stop! What are you talking about? Can you focus on the key points, my project is done so fast and so well, you just ask me these things?

These are the key points, otherwise no one will read the news!

...

farewell!

Ge Xiaotian turned around and boarded the business jet that flew directly to Amur.

Why go?

Take your dog home to celebrate the New Year, and take a look at the steampunk and the Great Sage sculptures by the way...

on the plane.

Seng Sanhui reported: Boss, Zheng He's treasure ship has been built.

Finish the cross-sea project first, wait until the first phase of Zaoshi New City is completed, and before it goes on sale, start Zheng He's voyages to the West project, advancing both land and water, and marching to the south of the Yangtze River! In addition, when the time comes, I will have a good discussion with the leaders of Fuzhou University in Jianfu Province Let's talk, fill in the project of the platform's provincial channel.

...

There are more than 20,000 overseas construction workers. After finishing the cross-sea project, they can't be idle, right?

It makes sense!

By the way, has Nan Bangzi's project payment arrived?

The first phase of 6 billion Franklin, paid by Incheon, has been deposited in Nanyang Development Bank.

Six eight forty-eight, nearly 50 billion red notes...

Ge Xiaotian thought for a moment, The outstanding payment will be reserved for Daqingshan Ancient Culture Project, and the cross-sea project will continue to use Mr. Zhuang's Nanyang Development Bank loan. The six billion Franklin will be transferred to Huaxia Trust. I will talk to CNOOC in the next year. For Huaxia-level enterprises, they must know my strength, and if they are rich, they will have confidence in their hearts, which is enough to play a big game.

Crude oil stocks?

If you think about it too much, it's just a waste of money to invest in it. I mean, with CNOOC and the Tiancheng system, apply to the superiors, scare Huaxia Petrochemical, and talk about the acquisition.

Are you afraid that you will be beaten...

Offshore construction, the steps are cumbersome. If you talk about it in detail, you can almost write a book. There is no water in the book. You can read it if you can understand it. It doesn’t matter if you don’t understand it. The main plot is the Spring Festival. Really spent the first Spring Festival.
