Chapter 1309 The first show of the drilling dragon
An hour later, the Earth-Drilling Dragon accurately emerged from the tent one kilometer away.
Underground, a tunnel with a diameter of thirty meters has been constructed.
One hour, one kilometer, and a tunnel with a diameter of 30 meters was completed. This speed is too scary. If you don't see it with your own eyes, who would dare to believe this is true.
Everyone stood inside the tunnel, and the dark tunnel seemed particularly spacious. The horizontal ground had been hardened, as had the surrounding walls.
The five-meter wall behind forms a huge protective shell, and the forty-meter cutter head drills through it. Excluding the ten-meter concrete thickness on both sides, the entire tunnel width and height are thirty meters.
The width and height of thirty meters are completely sufficient. Even if the lane is five meters, it is still a six-lane main road.
With such a width and height, there is no problem at all whether it is used for passing cars, subways, trucks, or integrated pipe corridors.
"Sacred weapon..."
After the technicians completed the exploration, they couldn't help but sigh. Damn it, with such an artifact, many infrastructure projects will become extremely simple.
It's so troublesome to use this thing to build subways. If you just drill in, a city's subway may be completed in a month or two.
To build a mountain tunnel, just rush there and it's done. They have tested it to the extreme, and even the steel plate can be drilled through easily, let alone stone. Even the hardest granite is like dregs in front of this thing.
.
"Notice further and change the construction plan of the private Maoli Industrial Park. The construction plan will be changed from above ground to underground."
Zhang Fan directly issued the order. With this thing, there is no need to bother building things on the ground.
Just build it directly underground, which is not only fast, but also saves money, and is also safe. If you build it on the ground, you are afraid of being damaged. But when you build it underground, there is such a thick protection that even if you use explosives, you can't damage it.
Action, the private sector took action. The private sector led to the east, and the private sector led to the starting point of the Maoli Industrial Park.
Huge heavy machinery became busy, excavating the soil from the ground, and then 3D printing equipment was built directly on top.
The entire station was quickly prototyped under the operation of the printer. The coagulant used for printing this time was the same as that used by the Earth-Drilling Dragon. After obtaining a new formula, it was natural to use it.
The mass of this coagulated liquid is twice as high as the original coagulated liquid.
Therefore, the quality of the construction is stronger. The entire station is very huge, with five floors above and below, each with its own functions.
Passenger and freight transport will not interfere with each other, and roads and railways will not interfere with each other.
Construction has begun, and this construction is live broadcast. Many people who have nothing to do are watching the live broadcast.
"The Zhang Group's infrastructure capabilities are so powerful..."
"The construction speed is really impressive. Such a large auto show can be completed in just a few days after it is announced..."
"Brother Fan is awesome, but why is this station underground..."
"I asked, why does it look a bit like a subway station..."
"Isn't the original plan on the ground..."
Some people quickly discovered something different. The originally planned station was above ground.
But now the entire station has sunk into the ground, and the foundation of the entire auto show has been dug dozens of meters underground. Although the construction has not been completed, it can be seen that most of the main body has sunk into the ground.
"Let me go, what kind of machine is this?"
Soon, a huge motorcade appeared on the live broadcast screen. This time the motorcade was not covered with camouflage cloth.
The body of the Earth-Drilling Dragon is directly held outside and fixed to the car by fasteners.
The huge vehicle, like a missile vehicle, pulled the Earth-Drilling Dragon to the construction site.
After arriving at the construction site, the crane directly hoisted the earth-boring dragon down and docked it. Soon the ground-boring dragon was docked. The body of more than 100 meters looked particularly huge.
"Hello, friends who are watching the live broadcast. You are in luck today. You can see the Tai equipment behind me. This equipment is the latest generation of shield machine developed by Zhang's Heavy Industry. This Tai shield machine has a loud
Its face is called the Earth-Drilling Dragon. As for how powerful it is, you will be able to see it soon..."
During the live broadcast, an anchor came out and introduced it. After listening to the introduction, many people became curious.
Then, the burrowing dragon started to move. Its whole body moved like a big earthworm.
"What the hell is this..."
"Are you a shield machine? Don't fool me..."
"Why do I feel like a big earthworm..."
"I'm going to start drilling..."
With the attention of many people, the shield machine accurately positioned itself and then drilled straight into the marked place.
This is not the most important thing. Everyone soon discovered that the speed of this earth-burrowing dragon is a bit fast. The huge body actually burrowed into the underground soil at a speed visible to the naked eye.
At the rear, a specially made hose sprays out the crushed sediment. The sediment is very crushed, and a large amount of sediment is sprayed out, which is then transported away by engineering vehicles.
In just ten minutes, the huge body of the Earth-Drilling Dragon was completely drilled into the earth.
"I'll go, it has to be more than a hundred meters away, right? It's only been a few minutes..."
"Oh my god, is this a shield machine? Whose shield machine is so fast..."
"It's so scary..."
"It won't be so soon..."
People watching the live broadcast went crazy, and many people quickly contacted their friends to let them watch the fun. Soon the construction also attracted the attention of various countries.
The private collection was very mysterious a few days ago, and they didn't know what it was. Now this thing has finally been unveiled.
Shield machine, but this shield machine is a little different from ordinary shield machines. So more and more people are paying attention to it.
Under everyone's attention, the Earth-Drilling Dragon began to work continuously. After becoming proficient, the speed gradually increased. It soon reached the maximum speed of five kilometers per hour.
This speed is frightening for a shield machine. Under the camera, everyone was stunned.
A huge underground tunnel appeared in front of everyone, and a large amount of soil was sprayed out and continuously transported away.
As the tunnel got deeper and deeper, the staff behind it became busy. Portable ceiling lamps were attached to the tunnel to provide lighting.
The dark tunnel lit up, and the staff didn't need to do anything else. They just needed to pull away the sprayed soil.
It is also very convenient to pull away. The width of 30 meters is enough for a large muck truck to drive in. The injection port can be adjusted at will to spray excess soil directly into the muck truck.
The tunnel grew at a speed visible to the naked eye, and the anchor also introduced the power of the Earth-Drilling Dragon in detail. After learning how powerful this Earth-Drilling Dragon was, countries around the world were shocked. This equipment is so crazy.
