Everyone's eyes widened as four excavators were separated in four lanes. After the four excavators took action, they slanted directly into the ground.
Just like an earth drilling machine, it moves forward while drilling, and the efficiency is very high. A large amount of earth comes out of the excavation port, and the muck trucks are lined up. After one car leaves, another car picks up directly.
The excavator is moving forward slowly, at a speed of about five meters per minute. It seems slow, but the efficiency is already frighteningly high.
"This is the latest rotary excavator developed by our Longteng Heavy Industry. The excavation wheel is four meters wide and can excavate to a depth of two meters at a time. It can excavate about 40 cubic meters of earth per minute."
The staff introduced it. Everyone stared at the excavator. The rotating shovel was like huge teeth gnawing at the ground.
Walk while chewing. The depth of each excavation is two meters. Use special skills to walk over, and there is a deep trench with a depth of two meters behind.
The ground is still very flat. The entire excavator is like a ground mouse, moving forward little by little in the ditch.
This kind of efficiency is much higher than that of ordinary excavators. However, huge efficiency represents powerful technology.
The power unit of such an excavator must be very powerful. Technology, they saw the technology of Longteng Heavy Industry.
In fact, this excavator is no longer driven by traditional fuel. The rotary excavating shovel in front is actually driven by a huge electric motor.
The crawler tracks are also powered by electricity. The battery pack uses an all-solid-state battery pack and also has a transformer device.
The main function 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 cars in mines. They are all driven by electricity, and the engines are used to generate electricity.
Five meters in one minute, the excavation distance of hundreds of meters took only twenty minutes.
It only took an excavator twenty minutes to dig a deep trench with a depth of two meters, a width of four meters, and a length of one hundred meters.
When the excavator was digging, another piece of equipment had already entered the deep trench and was following behind the excavator. This piece of equipment was a multi-function roller.
In front of this kind of road roller is a special rotary tiller. The rotary tiller can rotary till and crush the soil. The roller at the back then re-compacts the soil, thus ensuring the quality of the roadbed.
The programs are closely connected and do not interfere with each other but are very fast. Everyone cooperates with each other and does their own thing.
Assembly modules of assembly modules, road crushing of road crushing, shoveling and blasting of slag shoveling, earth pulling of earth pulling, excavation of excavation, and road compaction of road.
The efficiency was extremely high, and everyone's eyes widened. Driven by curiosity, no one felt that time was passing away at all.
An hour later, the entire 100-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 solidized, and this efficiency made everyone swallow their saliva.
"In order not to waste everyone's time, this year we will use a depth of two meters as an example."
The instructor smiled and said that only then did everyone realize that the module had been assembled. The module was one hundred meters long and was right in front of the road that was dug into a deep trench.
Just after everyone became curious, the special bridge erecting machine started to move. Two rows of wheels dragged its huge body to the front of the module.
Then a strange scene happened. The wheel that was originally vertical suddenly turned and turned horizontally.
Then the two rows of wheels unfolded to both sides, and the distance between them became larger and larger. Only then did everyone discover that the beam in the middle of the bridge erecting machine could actually grow at will.
The middle beam is actually folded, and expands outward with the wheels. The folded weight unfolds little by little.
The two rows of wheels of the bridge erecting machine moved farther and farther outward, and stopped when the two rows of wheels reached a certain width. Only then did everyone discover that the width between the two rows of wheels was enough to accommodate the modules.
The distance between the two rows of wheels is just outside the deep trench being excavated.
"This is our variable pipe gallery bridge erecting machine. The maximum variable width can reach 120 meters..."
The instructor proudly said that the technology of the variable bridge erecting machine is very high and the most difficult variable beam material.
It must have sufficient performance to be able to support the bridge erecting machine. After all, the things this thing has to lift are very heavy.
This bridge erecting machine can lift tens of thousands of tons of heavy objects, and its performance is very impressive.
Under everyone's attention, the bridge erecting machine slowly moved forward and swallowed the module directly. After swallowing the entire module, the lifting steel cable above was directly fixed at the lifting position of the module.
The huge module was hoisted. The entire module is very large. It is two meters high, trapezoidal, 30 meters wide at the top, 32 meters wide at the bottom, hundreds of meters long, and weighs thousands of tons.
The module was hoisted, and the bridge erecting machine moved forward slowly. Ten minutes later, the bridge erecting machine reached the predetermined position. Then the lifting steel cable was slowly lowered, and the huge module was placed steadily in the deep trench.
It is not only stable, but also very accurate. The displacement deviation is within one centimeter. After the entire module is placed inside, the bridge erecting machine slowly retreats.
The muck truck that had been prepared dumped the truckloads of earth into the ditch. The remaining space was filled in. After filling, the road roller compacted it again, and the whole thing was completed.
It took an hour and a half to transform a road thirty meters wide and several hundred meters long into a comprehensive pipe corridor.
This kind of efficiency makes countless people take a breath of cold air. This speed is too scary. This kind of speed and this kind of efficiency are too important for the city.
After all, in the process of urban reconstruction, people's livelihood must also be taken into consideration. If it is reinforced concrete, it will probably take at least a month to build a one-kilometer road.
But now if we use these equipment, maybe it can be built in a day or two. In this way, the city can build roads one by one, and the construction will be completed very quickly.
Modular comprehensive pipe corridors and such advanced equipment make the construction of urban comprehensive pipe corridors extremely fast.
Shock, everyone felt shocked. Only at this moment did they truly realize what super efficiency and dragon efficiency were.
Now Longteng Group has taken advantage of modularity. Many things are modular. The benefits of this kind of modularization 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 so shocking. I'm afraid there will be fewer and fewer places to employ people on construction sites in the future."
A construction boss sighed. This kind of equipment and efficiency will significantly reduce the number of workers.
In the future, large-scale infrastructure construction can stimulate the economy, but its ability to stimulate employment will become weaker and weaker. This is the consequence of technology.
