Everyone's eyes widened, and four excavators were separated in four lanes. After the four excavators moved, they drilled directly into the ground at an angle.

It is like a drilling machine, and it is very efficient to move forward while drilling. A large amount of earthwork came out of the excavation, and the muck trucks lined up, and one car left and the other car was directly connected.

The excavator is moving slowly, at a speed of about five meters per minute. It seems slow, but the efficiency is already scary.

"This is our latest rotary excavator developed by Longteng Heavy Industries. The width of the excavation runner is four meters, and the depth of excavation can be two meters at a time. It is possible to excavate about 40 cubic meters of earth per minute. ”

The staff introduced. All eyes on the excavator. The rotating shovel gnawed like a huge tooth on the ground.

Walk while gnawing. Each excavation is two meters deep. Playing a stunt and walking over, there is a deep ditch with a depth of two meters behind it.

The ground is still very flat. Rats, little by little in the gutter.

This efficiency is much higher than that of ordinary excavators. But great efficiency means great technology.

The power plant of such an excavator must be very strong. technology, they saw the technology of Longteng Heavy Industry.

In fact, this excavator is no longer a traditional fuel drive. The rotary digging shovel in front is actually driven by a huge electric motor.

Including the tracks are also electrically driven. The battery pack is an all-solid-state battery pack, and there is also a transformer device.

The main role of the huge diesel engine is to drive the generator to generate electricity. The electricity generated by the generator charges the battery.

Such equipment is very common, such as the super-large mine cart in the mine. They are all electrically driven, and the engines are used to generate electricity.

Five meters a minute, hundreds of meters of excavation distance, it took only twenty minutes.

It took only twenty minutes for an excavator to dig a deep trench two meters deep, four meters wide, and a hundred meters long.

When the excavator is digging, another type of equipment has entered the deep trench and follows the excavator, this equipment is the multi-function roller.

This roller is preceded by a special rotary tiller. The rotary tiller can crush the soil for rotary tillage. The roller at the back then recompacts the soil to ensure the quality of the roadbed.

The programs are closely connected, and they do not interfere with each other, but they are very fast. Everyone cooperates with each other and does their own thing.

The assembly module of the assembly module, the crushing of the broken road, the shoveling of the slag, the pulling of the soil, the excavation of the excavation, the rolling of the road.

The efficiency was incredibly high, and everyone's eyes widened. Driven by curiosity, people don't feel that time is being lost at all.

An hour later, the entire hundred-meter road had completely changed. It turned into a deep trench with a depth of two meters.

The bottom of the deep trench has also been crushed and solid, and this efficiency has made everyone swallow.

"In order not to delay everyone's time. This year, let's take a two-meter depth as an example. ”

The commentator smiled and said that everyone only found out at this time. The modules have been assembled. This module is a hundred meters long and is right in front of the road that has been dug into a deep trench.

Just after everyone was curious, the special bridge erector went into action. Two rows of wheels dragged the huge body to the front of the module.

Then a strange scene appeared, the originally vertical wheel suddenly turned, directly turning horizontally.

Then the two rows of wheels spread out in both directions, and the distance between them increased. At this time, everyone found that the beam in the middle of the bridge erecting machine could grow at will.

The middle beam turned out to be folded, with the wheels expanding outward. The measurement of the fold unfolds a little bit.

The two rows of wheels of the bridge erecting machine go outward more and more, and only stop when the two rows of wheels reach a certain width. At this time, everyone realized that the width between the two rows of wheels was enough to accommodate the module.

And the distance between the two rows of wheels is just outside the deep trench that was dug.

"This is our variable pipe gallery erecting machine, which can be up to 120 meters wide with variable widths......"

The narrator said proudly. The technology of the variable bridge erecting machine is very high. The most difficult material for variable beams.

There must be enough energy to support the bridge erecting machine. After all, the thing this thing is going to lift is very heavy.

This bridge erecting machine can lift tens of thousands of tons of heavy objects, and it can be very good.

Under everyone's attention, the bridge erector is slowly advancing. I swallowed the module directly. When the whole module is swallowed, the upper hoisting cable is fixed directly to the hoisting position of the module.

The huge module was hoisted up, and the whole module was very large. It is two meters high, trapezoidal, thirty meters wide above, 32 meters wide below, hundreds of meters long, and weighs thousands of tons.

The module is hoisted, the bridge erecting machine moves forward slowly, and the bridge erecting machine walks to the predetermined position after ten minutes. Then the lifting cable slowly descended, and the huge module was placed firmly in the deep trench.

Not only stable, but also very jīng. The displacement deviation is within one centimeter. After the entire module is placed inside, the bridge erector slowly retreats.

The muck truck, which had been prepared for a long time, poured a cartload of earthwork into the ditch. The remaining space is filled in, and after filling, the roller is pressed again, and the whole is completed.

It took an hour and a half to turn a road 30 meters wide and hundreds of meters long into a comprehensive pipe gallery.

This efficiency has given countless people a breath of fresh air. It's terrifying. This kind of speed, such efficiency, is too important for a city.

After all, in the process of urban transformation, we must also pay attention to people's livelihood. If it's reinforced concrete, a one-kilometer road down is probably at least a month.

Now, if you use these equipment, you might be able to build it in a day or two. In this way, the city can be built one road at a time, and it will be completed very quickly.

The modular comprehensive pipe gallery and such advanced equipment make the construction speed of the urban comprehensive pipe gallery extremely fast.

The shock, the shock was felt by all. At this moment, they really realized what is called super efficiency and what is called dragon efficiency.

Now Longteng Group has played modularity. A lot of things are modular. The benefits of this modularity are also obvious, allowing Longteng Group to have higher efficiency and greater profits.

Especially after the development of various new materials, the cost of modularization has been greatly reduced.

"It's shocking. In the future, I am afraid that there will be fewer and fewer places to employ people. ”

A construction boss sighed. This kind of equipment, this kind of efficiency, so that the number of workers will be greatly reduced.

In the future, large infrastructure construction can stimulate the economy, but the ability to stimulate employment will become weaker and weaker, which is the consequence of science and technology.
