Chapter 562: Deep-sea construction, the Spring Festival is coming
As the saying goes, there is a dictatorship in the art industry.
Mr. Yu worked as a porter in a petroleum refinery, ran in external business, went to the first-line workshop, entered the logistics and statistics department, and served as the general manager of Guangqu Petroleum......
A set of processes has come down, don't look at it now as the leading big brother of Dongshan, but in terms of oil, it is better than the door clear, like what Chen Dong, in front of him, at most he is a halfway monk.
If Ge Xiaotian doesn't ask for the big Buddha of Mr. Yu, doesn't want the old money and the old oil, and doesn't dig the old petrochemical team in Guangzhou, it is simply a shame for the Tiancheng corporate culture shaped by Xiaohuang.
However, Mr. Yu agreed to help, which was equivalent to standing on the opposite side of Chen Dong.
In order to have a buffer period, or to leave enough time for his own preparation, Ge Xiaotian did not immediately go to the capital to visit the top management of CNOOC after calculating Tiancheng's remaining fuel storage in China, but suspended the second phase of the domestic Xingyue Bay project and started the third 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 21 points of the GLONASS system to assist positioning.
The 20,000 employees were scattered to 21 points, and it was not easy 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 complex.
In fact, there is a huge problem with multi-point starting, that is, there will be errors when connecting with each other.
In case of deviation in a certain range, it is estimated that the entire project will deviate from the design requirements.
Therefore, most enterprises will choose a construction plan that goes hand in hand, docks in the middle, or goes to the end of the road.
However, Tiancheng has a system.
First, rely on the GLONASS positioning system to let the strong man arrive at the construction area by boat, and then open the market map 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 construction drawing annotation points that are magnified countless times......
In the future, 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 the strong man, which is about 0.1mm.
Let's call it Tiancheng's unique 'pulling line' method.
Now, a week has passed, and there are six more floating islands in the 21 construction areas.
That is, it is built by six system A-type ships and is used to build an offshore platform for various system buildings.
Now the floating island has been transformed into a staff accommodation area and a building materials storage area, each of which radiates three construction areas, and the extra three construction areas are on land, without floating islands.
January 13th.
At eight o'clock in the morning, the sea was hazy.
Floating Island No. 1.
Ge Xiaotian wore a life jacket, a search and rescue device, a nutrient solution in his waist, and a device similar to a Steadicam camera kit on his shoulder, facing the howling cold wind, and walked to the construction site.
On the edge of the floating island, nearly 1,000 Tiancheng employees are busy.
In accordance with the requirements of the contract, 2,000 foreign workers received from Incheon are carefully studying 'holding steel bars' and 'pouring cement' in the floating island building materials storage area.
This is Tiancheng's unique advanced technology!
"Students, in the last class, we were familiar with the main process of deep-sea construction and the precautions of each link, so today we will refine these steps, so that you can know 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......"
"Over the past 30 years, the tide has risen by an average of ±4 metres with an error of no more than 10 centimeters. The wind speed of the center of the strongest tropical storm is 25 m/s, and the wind speed of the strongest typhoon is 45 m/s, and the super typhoon has not yet occurred......"
"The trestle bridge I talked about in the last class is the floating island under my feet, and I rely on transport ships to connect to the logistics ...... of Weicheng."
"Our staff has already installed the equipment......"
Ge Xiaotian stepped into the engineering island that had been docked with the floating island, and climbed into the clamp-type robotic arm workshop in the center of the town.
Previously, he thought it was a super pincer for clamping huge loads for loading and unloading, but upon closer inspection, he realized that it was a super vibrating pile hammer.
What does that mean?
It is through the top winch (similar to the equipment of the tower crane to retract and release the steel cable), the claw-shaped pliers at the top of the mechanical arm, and the round iron bumps on their tops, can be lowered into the deep sea like a chain hammer.
Well, just putting 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 one and a half meters, and a wall thickness of 10 mm, relying on a steel cable of tens of meters, or even hundreds of meters, to go vertically to the bottom of the sea......
Then, the huge iron bump on the top of the claw-shaped pliers, driven by electricity, can generate a frequency of hundreds or even thousands of impacts per second, acting as a continuous force, and then like a nail, the hollow steel casing is driven into the seabed......
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 ......
and so on to meet the construction requirements, splicing the rest of the steel casing until the sea surface is exposed......
Finally, the water, mud, crushed rock, etc. in the casing are drained, and the reinforcement cage and underwater anti-corrosion cement are injected......
The first link of the deep-sea foundation pile is completed.
It's 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 with the camouflaged engineering island in the center of the town, Tiancheng is well placed to undertake projects in deeper seas, including oil exploration platforms.
Ge Xiaotian operated the robotic arm on the spot and explained on the spot, and before he knew it, a day had passed......
And his third class is also coming to an end.
Engineering class is like this, listen to the clouds, take a look, take a look, touch, practice......
, it's so hard!
Mainly, this also involves the production of the steel casing, the docking process of the steel casing, the automatic alignment of the vibratory hammer, and whether the steel casing meets the construction standards (to avoid being knocked crooked like nails)......
as well as underwater cement composition, anti-corrosion process, performance indicators......
and the need for attention in the transportation and installation of reinforcement cages.
Since Tiancheng only has one engineering island and two pincer robotic arms, in order to meet the construction, the two positions must have 8-10 mechanical operators to carry out all-weather piling.
Fortunately, after upgrading the four-level system, sailors and helmsmen who have been transferred from strong men can already continue to change jobs and become marine mechanics.
After talking about this, I listened to the students for a day and watched them for a day, and went back to study.
The next day, January 14th.
Ge Xiaotian struck while the iron was hot and started the fourth class.
The reason why I am in such a hurry is because ...... It's going to be the Spring Festival, and the group has a three-day holiday.
So, for the rest of the course, he was going to spend six days to get it done.
It's just strange that none of the bosses who listened to the class before bought the course.
"I really thought I was running a game, buy early and enjoy it early, and buy it late to 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 needed 3.5 million!
Another standard: Spring Festival promotion, the price will increase after the year!
As well as uploading parameters and photos of numerous devices.
If you want to make money, you have to not only buy it, but also lease my machinery!
"Students, today we will talk about the design and construction of the viaduct. ”
"It may sound like it overlaps with the courses of Professor Hu or Chief Engineer Liang, but this is linked to the bridge piers, and the level and role we talk about are different. ”
"Since the construction of the substructure of the bridge began as soon as the design of the substructure was completed, the design of the superstructure was limited by the strength of the substructure that had been determined, and the surplus reserved by the substructure had to be accurately judged. If the surplus is large, the degree of freedom in the design of the superstructure is large, which can easily lead to an increase in cost, and it is very important to accurately predict the surplus when using the rapid construction method......"
"The viaduct on the entire line adopts a PC beam with a span of 50m, and a joint ...... with 5 spans"
"The design is so that the use of uniform spans in straight sections reduces the design effort and also reduces the construction time. ”
"The box girder girder is 3m high, the concrete strength is 45MPa, and the whole span frame is used to construct the ......"
"The substructure is a gantry structure with a cast-in-place pile foundation and a bridge pier rigidly connected, and the substructure of the sloped section connected with the approach bridge is a cast-in-place pile foundation and a circular solid pier ......"
Ge Xiaotian talked about this and came to the prefabricated site of the floating island.
"The prefabrication plant is 25 meters high, 30 meters wide, and 210 meters long......"
"The precast beam of the viaduct is 50m long and weighs 1350t......"
"It takes 1d time for the precast beam to bind the reinforcement, and the concrete is supplied by the concrete factory adjacent to the precast yard, and after the concrete is poured, the steam with the highest temperature of 60 °C is used to cure for 17h to reach the early strength, so as to shorten the curing time, therefore, Tiancheng only needs 2d to make 1 piece of precast beam!"
"And how many of these factories do we have......
Ge Xiaotian pointed the camera at two nearby floating islands in the distance, "12 at sea, two for each of the six floating islands. On both sides of Weicheng and Incheon, there are 50 such steam workshops to ensure that the bridge erecting machine and the floating crane are in place at the same time and supplied at the first time. ”
"Next, let's take a look at the production method......"
Before you know it, another day has passed......
In the next few days, Ge Xiaotian carried out the design of the approach bridge, the construction of the approach bridge, the cast-in-place pile of the main bridge of the cable-stayed bridge, and the foundation pile of the tower of the cable-stayed bridge......
As well as the corresponding construction, such as hoisting the cushion cap formwork, installing cables and shock absorbers, dealing with expansion joints, installing expansion joint monitoring systems, etc., to explain one by one, and even operate hands-on.
Subsequently, such as "large-section construction and construction accuracy control", "the use method of 6000t floating crane designed to greatly shorten the construction period", and "the main span steel box girder segment cantilever construction points...... It was all a course by Professor Hu and Chief Engineer Liang.
Such cramming will definitely require the help of the system university, which is why the course is set up in the multimedia teaching hall.
When the deep-sea piling link is halfway through, the land and beach projects have begun to lift the beams.
Taking this opportunity, the Department of Civil Engineering of Dongshan University of Construction and the Department of Cross-sea Engineering of Tiancheng Technical College collectively applied for exchange students of Nambangzi Incheon University, and then arrived at the construction site to start the final internship examination of the first semester.........
Tiancheng has made such a big move, which has caused an uproar in the Chinese education circles.
Professor Hu even said that if there were no enrollment restrictions, Dongshan University would be able to recruit at least 50,000 new students next year!
You must know that Tiancheng's treatment in China has always been super high, and it is ...... overseas.
Even students can get a subsidy of 100 red bills a day!
The reporter who heard the news came to block Ge Xiaotian, who was about to return to China, before the arrival of the Spring Festival, that is, on January 21 and the 27th day of the 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 you wear stockings and short skirts in winter?"
"Mr. Ge, there is a rich woman who bids for your dinner and spends more than one million, and most of the year has passed, why have you kept no-showing, is it because of a weak heart?"
"Stop! What are you talking nonsense? Can you focus on the key points, my project is done so quickly and so well, you just ask me this?"
"That's the point, otherwise no one will read the news!"
“......”
Leave!
Ge Xiaotian turned around and boarded the business plane that flew directly to Amur.
Why go?
Pick up your dog home for the New Year, and take a look at steampunk and the Great Sage sculpture by the way......
on the plane.
Seng San reported: "Boss, Zheng He's treasure ship has been built. ”
"First of all, we will finish the cross-sea project, and then start Zheng He's project to go to the West before the first phase of Zaoshi New Town is completed and put on sale, and then I will enter the south of the Yangtze River by land and water! In addition, when the time comes, I will have a good chat with the leaders of Fuda University in Jianfu Province and fill in the project of filling in the strait of the platform province. ”
“......”
"With more than 20,000 employees in overseas construction engineering, we can't be idle after completing the cross-sea project, right?"
"Makes sense!"
"By the way, has the payment for the project of Nan Bangzi arrived?"
"The first tranche of six billion Franklin, paid by Incheon, has been deposited with Nanyang Development Bank. ”
"Six, eight and forty-eight, nearly 50 billion red banknotes......"
Ge Xiaotian thought for a moment, "The unpaid will be reserved for the Daqingshan Ancient Culture Project, the cross-sea project will continue to use the loan of Zhuang Lao's Nanyang Development Bank, and the six billion Franklin will be transferred to Huaxia Trust, and I will talk to CNOOC after the year, they are all Chinese-level enterprises, they must know my strength, and I have money in my heart, which is enough to play a big game." ”
"Crude oil stocks?"
"I think too much, this money is thrown into it, I mean, and CNOOC, plus Tiancheng system, scare and scare Huaxia Petrochemical, talk about the acquisition. ”
"You're not going to be beaten......"
