No. 243 Infrastructure



"Mr. Wu, we are currently conducting in-depth research on special silicon molecules to see if it is possible to develop more extended series!" Another researcher was also a little embarrassed.

It was Mr. Wu who discovered the special silicon molecule. The starting point of Tao Ran's reinforced coating was also the use of a special silicon oxide molecule. After Mr. Wu's sublimation, the current super reinforced coating was obtained.

They are still conducting in-depth research based on Mr. Wu's work and still need his assistance. Their level is really not up to par, and they hope not to hold Mr. Wu back.

"Very good. This is a topic worthy of in-depth research. You can continue to dig deeper and add more creativity!" Wu Tong nodded with a smile.

She discovered this special substance and made some superficial use of it. However, it is not possible to promote it on a large scale domestically and globally for the time being. Therefore, more in-depth research will be left to these team members to slowly dig out more gold mines.

"I look forward to you creating more achievements!" Wu Tong cast an expectant look at the team members, and then continued: "Next, there is a basic task that requires your assistance!"

"Mr. Wu, please go ahead. We promise to complete the task!" Everyone looked at Wu Tong solemnly. Mr. Wu finally had a formal use for them. They had to complete the task properly and demonstrate their own value.

Wu Tong laughed. "Don't be so serious. I just had an idea. I hope I didn't burden you. I need you to help me collect data on the common infrastructure of highways, super highways, etc. in the world, as well as information on various adhesives and parameter data of some basic materials!"

If you want to do your work well, you must first sharpen your tools. Wu Tong wants to create a roadbed that is easy to build, has low construction costs, is earthquake-resistant and disaster-resistant, and durable... and has excellent functions. For this section, a basic understanding is essential.

"Got it, Mr. Wu. We will provide you with the information you need within three days!" Tao Ran and his group promised in unison. They will collect the information Mr. Wu needs as quickly as possible, complete the task assigned by Mr. Wu, and also be prepared to assist Mr. Wu in completing the experiment.

As soon as they heard Mr. Wu's request, they knew that Mr. Wu was going to do something big. They looked at each other, and they were all excited and expectant. They were going to participate in such a big move, not to mention the honor and pride!

"Research tasks should be arranged appropriately. Your health should be prioritized. Unless there are special circumstances, try not to stay up too late!" Wu Tong urged them before leaving. We are all young people with a long future ahead of us. These are all promising young people who could become pillars of society, and we must not let them be harmed by neglecting our own selves.

"Yes, Mr. Wu, we will pay attention!"

Soon, the information Wu Tong needed was gathered in her hands. She was gradually adapting to the role of team manager, letting go where necessary and delegating trivial matters. This also gave her more time to use on projects that needed her more.

In fact, a better model is that the team can formulate a certain appropriate direction, and she will do the screening. The ideal state is actually similar to the aluminum alloy material studied by the teacher, and even slight deficiencies are fine. On this basis, she will improve, extend and optimize.

However, Wu Tong did not insist on this. Starting from scratch, for her, determining the direction of demand would not cause too much trouble.

China's infrastructure has always been famous, especially after six or seven years, it has jumped to the first place in the world with a total mileage of 140,000 kilometers of highways, and this figure is still increasing. In terms of infrastructure, the country has always spared no cost just to facilitate the people and connect the whole country.

However, current data shows that the total mileage of domestic expressways is only nearly 70,000 kilometers, which is still half of the total mileage required to make the list.

Wu Tong thought that if he could produce favorable results as soon as possible, enter into actual experiments, and then promote them at a faster speed, it would save the country some financial expenditures, create greater mileage, and spread miracles across the country, thus promoting development.

According to data, expressways are designed to accommodate multiple types of vehicles traveling at high speeds, so the road surface requirements are very strict. Currently, expressways are generally built in multiple layers, with the road surface usually divided into four layers. This is to prevent inclement rain and snow, when water seepage from the ground will carry away the soil at the bottom.

Over time, problems such as potholes and ground subsidence will form inside, causing road collapse and triggering major disasters.

The bottom layer is the soil base, which is a layer of natural soil that is repeatedly compacted by a roller; the next layer up is a crushed stone layer composed of various crushed stones, which is used to enhance the bearing capacity of the roadbed;

The next layer above is a coarser asphalt layer, which is composed of a mixture of particles and can disperse the pressure from the surface; the top layer is an asphalt layer composed of a finer mixture of asphalt particles. It is also the layer that the car contacts, so it mainly provides a smooth surface.

After all, when driving at high speed, every pothole will increase the driving risk.

This is the basic construction process for surface highways. In addition, due to unmet demand and unique topography, elevated sections of highways are typically constructed using steel beams, rebar, and concrete. These sections are typically constructed in sections and then assembled, with a small seam between each section.

This design can prevent cracking of the road surface due to expansion and contraction.

Wu Tong circled the key points on the asphalt and steel beam reinforced concrete complex, gazing at them for a long time. If traditional steel can withstand the overload demands of highways, what about MC-4 special steel? Can it be used in a wider range of applications?

Today's buildings are no longer built with traditional bricks and stones. Reinforced concrete is the main raw material used. The formwork is closed layer by layer, the steel bars are tied, and then concrete is poured to form an overall frame structure. Bricks can only be used as partition walls.

The speed of China's infrastructure construction is beyond people's imagination. Modular integrated buildings are built, and the process is like building blocks. A 57-story high-rise building was built in 19 days. The title of "Infrastructure Maniac" is resounding throughout the country.

Can this rapid model be applied to highways to alleviate the difficulty of starting a highway, where the fastest speed is two months per kilometer?

Wu Tong's gaze gradually deepened, and the reserve knowledge in various fields of engineering and materials set off a tornado in Wu Tong's mind, which gradually condensed into a devastating storm, stirring up tiny sparks, turning dots into lines, and lines into pieces... and spreading like a prairie fire.

With pen and paper in hand, Wu Tong was naturally ready to start the deduction.
