Chapter 59 Snow Tunneling Machine

The vigorous production campaign has begun, and what Nanjing needs is a tunnel boring machine that can dig tunnels in the snow!
The roadheader is a new type of advanced tunnel construction machine that uses rotary cutters to excavate, simultaneously breaks the surrounding rock in the hole and excavates, and forms the entire tunnel section.

Tunnel boring machines are divided into two categories, namely digging soft soil and rocky formations.

It is customary to use shield tunneling in soft ground, which is a highly technical manufacturing equipment.

But it refers to the 21st century. In this technological era of more than 30 centuries, there are already many people who can make this.

The basic technology Nan Jing obtained from the experience potion, as well as the craftsman Julian and other female workers in the base, included the corresponding technology.

Tunnel boring machine is a highly intelligent tunnel construction major technical equipment integrating mechanical, electrical, hydraulic, optical and computer technologies.

Nanjing and Julian designed a style specifically for the current snow environment, and the rest provided technical and technical support.

Susan and Katerina are responsible for the electro-optic and computer aspects, and Verel and the original logistics staff in the lake center base are responsible for the production of hydraulic materials.

Celia and Winter are mainly responsible for safety issues. The top of the base has been covered by thick snow, as if covered with more than a dozen layers of quilts. Both breathing and perception have been affected. You must use searchlights to see clearly thing.

Except for a few hours when the sun's rays are the strongest, the rest of the time is basically pitch black because the light cannot penetrate the five-meter-high snow layer.

Even at noon, it still needs lights to illuminate.

Breathing is also a big problem. Basically, if the distance from the exit is too far, symptoms of dyspnea will appear.

Nan Jing and the others carefully hollowed out the thick snow in the base, and after melting the snow in the house, they built an underground shed with various props.

Use flat plates and other things to compact the snow on the top and left and right sides. After a night of temperature and humidity, it becomes a building like an ice palace the next day.

"It's too laborious to do things manually." Looking at the darkened space around him, Nan Jing said, "The boring machine doesn't need too much power, but the speed and stability must be higher."

Julian said: "The current snow layer is relatively soft, and it is still windy and snowy outside. Considering the impact of extreme weather on the ground and the impact on our roads, it is better to be prepared."

Nan Jing said strangely: "Do you think there are still creatures walking on the snow outside?"

Julian said: "It should be gone. For monsters and ordinary humans, there is now a sea of ​​snow outside. If they fall, they will be drowned by snow."

"However." Julian said affirmatively: "Some machines can drive in this environment, such as snow propellers specially used for this situation."

Nan Jing has this thing in his memory, and its performance is similar to that of a jet ski, but with stronger propulsion, and it uses the powerful propulsion to glide quickly on the snow.

Obviously, the snow does not have the buoyancy of water, and if you want to act on the snow, you need much higher technology.

People can float on water, but they will definitely sink in snow.

So once people and monsters fall into this thick snow layer, they will basically starve to death.

Even zombies will enter hibernation mode in this situation, because their limbs are completely numb and become frozen zombies.

Compared with the authentic underwater environment, the snow environment is harsher, and the action is more blocked than underwater.

But there is also a little bit better, there is more breathing room.

Nan Jing said: "It's better not to walk on it. Even if you get the snow propeller, breathing is still a problem in the strong wind outside. The body temperature will pass faster and you won't be able to walk far."

Julian nodded, looked around and said, "Build the boring machine first. When we finish building it, the snow outside will also compact the bottom snow, which is also beneficial for us to move forward under the snow layer."

Nan Jing walked towards the completed workshop, "Go on, I figured out a lot of technologies while working, and with my current technology, I can easily become an engineer in another era."

Julian said with a smile: "It's okay in this day and age."

Nanjing is in a good mood. Although the working environment here is much harsher, working with all kinds of smart beauties makes me feel extraordinarily motivated!

After spending a few days, a snow boring machine modified from several vehicles was built!
Nan Jing stood in front of the snow tunneling machine. This tunneling machine has a wasteland style, and it looks like a scrapped assembly.

All kinds of materials are reused from waste, whatever can be used can be used, as for the shape and stability...

From the appearance alone, this thing can't give people a sense of high technology, let alone the shock of being ahead of the times.

But it is this junk thing, this tunnel boring machine that may go wrong at any time, in Nanjing's era, it would not be able to get down without 100 million.

Julian climbed into the driver's seat, and said to Nanjing ahead: "I'm about to start! Get out of the way!"

Nan Jing moved to the side of the boring machine, waiting for Julian to start this dilapidated machine that condensed the fruits of everyone's labor.

The position of the drill bit of the roadheader is in the spiral shape of ice cream, because it is not for the function of digging rocks. In order to cope with and strengthen the broken snow layer, this roadheader adopts a manufacturing process that meets the current needs.

Accompanied by a dull roar, this large rusty metal car began to hold the rotating probe high and rushed out!

Buzz~ The boring machine rushed out as if out of control, and soon crashed into the snow wall in front of it.

The snow block is equivalent to a piece of paper in front of the boring machine. The fluffy snow block is pierced by the drill bit and squeezed to the outer circle. After the whole body of the boring machine goes in, the density of the snow layer that was squeezed together increases again. Some.

Julian directly drove the excavator forward for more than ten meters, and continued to move forward, leaving only a trace of black tires and a red light at the rear of the car.

Nan Jing and the others walked to the entrance of the snow cave to check the condition of the snow path.

The snow cave is composed of a semicircle and a square. The upper part is a circle made by a drill bit, and the lower part is a square bottom surface formed by the propelling tracks on both sides of the car body.

Just like a stable structure like a bridge hole!

Nan Jing touched the snow wall next to it, it had already been compacted.

Although there were some snow blocks falling from the top of the snow above the head, they were flattened by the rotating drill as a whole.

The temperature outside should have dropped to minus 90 to [-] degrees, and this is only the beginning of [Cold Winter]. After a while, the temperature may drop to minus [-] degrees, which is far more serious than what Meryl said before.

However, in the snow cave where there is no wind, the temperature does not drop sharply, and it will stabilize within a certain range afterwards.

In other words, the roadheader will be the main propulsion device for a long time to come!
