Super Technology Extractor - Chapter 119

Qin Shiqi didn’t know what Fang Hao came from, she took over a noise-cancelling headset from Fang Hao.

I also have a communicator in the headset. After putting it on, she asked uncertainly: “Boss, is this a shield machine?”

Shield tunneling machine, referred to as shield machine.

It is a special engineering machine for tunnel boring. Modern shield tunneling machine integrates light, mechanical, electrical, hydraulic, sensing, and information technology. It has excavation and cutting of soil, transportation of soil, assembly of tunnel lining, and measurement guidance. Correction and other functions.

Involves multiple disciplines such as geology, civil engineering, machinery, mechanics, hydraulics, electrical, control, and measurement.

In addition, it is necessary to carry out the “tailor-made” design and manufacturing in accordance with different geology, and the reliability is extremely high.

Shield machines are generally divided into manual shields, squeeze shields, semi-mechanical shields, mechanical shields, etc. according to the working principle. They can be divided into three types and four modes.

The reason why Qin Shiqi used an uncertain tone was entirely because of the way the shield machine was working.

“How to say, it should belong to TBM accurately. Generally speaking, the shield machine and TBM are the same, and they are all tunnel cross-sections, but strictly speaking, they are different.” Fang Hao said Walked towards a gray side.

TBM is more advanced and more complex than a shield machine, but with the continuous advancement of technology, the difference between the two is not too big. Both have the advantages of fast, high quality, safety, economy, environmental protection and labor protection. It’s just that some of them are more standardized in academic circles.

不论 But no matter how to define the difference between them, the technical development and application of these two devices have a very broad prospect in the field of underground engineering in China.

最早 The earliest research on the shield machine was a French engineer M.I. Brunel. Many people can’t think of the inspiration of the shield machine.

He started to study the shield machine construction after observing the stern drilling holes in the wood of the ship and discharging a kind of mucus to strengthen the cave from the body.

However, this process was very slow. From 1818 to 1843, the world’s first construction project using the shield machine method was completed.

With the technological development of the shield machine, it has been awarded the title of “King of Construction Machinery”. The requirements in various aspects are extremely demanding at the moment. Currently only a few countries in the world can make it.

Previously, China could only import shield machines from abroad, but could not introduce its technology. Western countries have been monopolizing the international shield machine market, let alone export related technologies to China.

But!

With the development of the manufacturing industry in China, we have completely relied on imports from the past, and have now been basically domesticated, and since then we have independently developed fist products.

Western countries did not expect that we would break through related technical difficulties so quickly, but what disturbed the West was that China immediately began to sweep overseas markets.

This is similar to the previous situation. If others block us, then we can certainly break through and immediately turn it into the price of cabbage to grab the market with Western countries.

Qin Shiqi followed Fang Hao next to Yihui, who was holding a debugger at this time. The debugger was plugged into a connection cable, and the other end of the cable was inserted into a USB socket at the end of the device.

On the sides of the device, there were several researchers wearing coats.

The white coat was already extremely dirty. It was covered with oil, yellow mud water, and red and white. Qin Shiqi could see that one of them had a large hole in his arm, which directly exposed the skin inside.

These people Qin Shiqi only saw photos in the company’s personnel files, this is the first time to see a real person.

They are young, and young is a bit doubtful whether these people can really have such a strong technical level.

It was just the fact that Qin Shiqi knew that without them, the company must still live on climbing models.

“I don’t know where the boss got these people from.” Thinking of this in his heart, he listened to Fang Hao’s conversation very seriously.

Ji Yihui pressed on the manipulator for a while, and the equipment slowly returned. “Boss, at present we have improved the housing components, and the components are being built.

的 We have completed the lining operation in your design. During the excavation process, the shield machine will first use the arc shell insert plate and insert it into the soil layer.

At the time of insertion, the calcium carbonate mixed solution can be injected. After the excavation of the soil layer, the rear end of the arc shell insert plate will be further die-cast and coated with a layer of tenacious reagent. “

Xu Yihui said, raising his hand and pointing forward, “It’s just that the cutting ability of the hydraulic motor-driven cutter head is a bit poor. We don’t have the corresponding technical reserves to improve it.”

“Well, this is a material limitation, so for the time being,” Fang Hao nodded his head, took the manipulator, and looked at the display data above, he was very satisfied with the current TBM tunnel boring machine.

This TBM tunnel boring machine is imported from Germany. In terms of industrial manufacturing technology, Germany is really strong.

When the import came, the digging diameter of this roadheader was 6.22 meters, and the maximum digging range was between 150 meters and 200 meters per day. Now it has been transformed and designed by Fang Hao, and their level of mechanical ability has been adjusted. Extensive changes.

The arc-shell case board retracted, Fang Hao made a gesture to Qin Shiqi, and walked forward one step.

In the middle section of the arc shell insert, there are diamond cutting blades placed horizontally. The diameter of each slice is about three meters, and they are densely arranged on the entire arc shell insert.

They can easily cut through the soil layer, and even if they encounter the rock layer, they can shred it away at a very fast speed.

There is also a set of integrated devices on the arc shell plug-in board that wraps the whole body, which contains: soil pressure sensor, synchronous grouting system, advanced grouting system, etc.

设计 This design is very common, most people think of it, but if there is no stubborn stone injection instead of bentonite, this design structure is a failure.

Finally, the machinery stopped completely, and Fang Hao checked the degree of wear of the blade around the arc shell insert.

OK, wear is not great.

Followed by cutter heads on the main unit, they are the main output equipment during the digging operation.

“A ash, come here, you look here.” Fang Hao carefully avoided those sharp knife tips, and there was a drop of lubricant dripping at the bottom of the knife plate.

Jian Yihui saw it, took the manipulator, and opened the interface of the oil supply detection system. The oil level indicator above was 80%, and it was falling rapidly.

After glanced at it, it stepped on the excavated mound with his feet, just like stepping on the sea surface, exuding a lot of lubricating oil from the mound.

“Boss, it’s the tubing that burst,” he said, yelling at the other professionals who were checking the gap between the tail shields, and several of them quickly removed the cutter head.

A multi-ton cutter blade is like a building block in the hands of several people, and it is disassembled into various parts in seven or eight minutes.

Qin Shiqi didn’t know if it was terrible, but looking at their working efficiency felt comfortable. UU Kanshu www.uukanshu.com

The two people who retreated to the retreat just watched them replace the parts, and then started to start the equipment. The hairy cutting sound rang again in the tunnel.

“Ah, the material is still not close.” Fang Hao put on the headset again, Qin Shiqi could not help but glared.

老板 “Boss, you are greedy. With this roadheader, I dare swear that the subway construction project in Anlin City will make Star Meteor Technology a big step forward.”

For a while, she had already estimated the value of this TBM in her heart.

If you use a digital camera and a point-and-shoot camera to describe it, this TBM tunnel boring machine is a combination of the two.

It does not require tedious operation procedures, where the soil layer is reinforced where it is dug, without the need for manual secondary work.

This is its simplicity.

它 And its advanced level does not need to compare with Qin Shiqi. She also has a general understanding. Her method is very simple. TBM roadheader is the most advanced roadheader construction machinery, so it must be better than TBM.

最 And the most critical thing is its mining speed. Compared with the traditional TBM, this device in front of it has improved efficiency by 35%!

Tunnels of about 300 meters per day can be dug. If it is a hard soil layer, it will be faster.

what does this mean?

3 kilometers in 10 days, and the engineering amount of 45 kilometers can be completed in only 150 days, and this time will be shortened to the extreme if the segmented construction method is used!

Lin Linlin always added up together, how can Qin Shiqi not be excited?

Suddenly, Qin Shiqi thought of something.

“Boss, I have a question. Is this equipment the main body of someone else? What about our patents?”
