A huge amount of mud, concrete and murky water poured out from inside the tunnel, as fiercely as a rising flood.
Countless yellow hats, red hats and white hats struggled to crawl in the flood, only to be ruthlessly swept aside by the flood.
On the road, construction vehicles were submerged and various expensive equipment were covered in mud!
Then, the scene changes!
The camera moves inside the tunnel!
An unprecedented video caught everyone's eyes.
At the end of the tunnel, a thick layer of brown mud covered the entire field of view.
Seeing this scene, countless hearts at the scene stopped beating, and their eyes all looked at the big screen far away from them without blinking.
Some contestants who responded quickly picked up pen and paper and quickly recorded!
The person sitting just one meter away from me is Xian Zihang, the Chinese cabbage.
While watching the videos, this top student from the University of Geosciences had already drawn mountain topography and geological maps on paper.
The camera then zooms in to the nearest point.
A voice also appeared later, sad and angry: "Humaling Tunnel."
"The total length of the bidding section is 13.61 kilometers, and there are ten regional fault zones and eight major faults."
As soon as this voice came out, all the contestants and the fifty examiners showed the most solemn and serious expressions.
Tang Anjun!
It's Tang Anjun's voice!
Hearing Tang Anjun's unique thunder sound, countless people's hearts beat wildly but they did not dare to speak out loudly.
Mr. Tang is in Humaling Tunnel?
Mr. Tang is on the front line?
With Tang Anjun's powerful and thick voice echoing in the examination room, Tang Anjun's figure also appeared on the big screen.
Wearing a red hat, he squatted down and picked up the layer of brown mud on the ground with his hands.
"Geological structure, Tertiary water-rich fine sand."
As soon as he finished speaking, Tang Anjun's hand slowly rose!
The next second, a column of water more than one meter high suddenly spurted out from under the brown mud that Tang Anjun picked up.
Immediately afterwards, the mud on the ground spurted out, submerging Tang Anjun's ankles in just a few seconds, and quickly rose to Tang Anjun's knees.
This scene fell into the eyes of the contestants at the scene, and countless people gasped and their hair stood on end.
Suddenly, everyone understood the content of this first test!
The third series is rich in gouache and fine sand!
This is a worldwide problem.
This problem has been encountered too many times, but no country or institution has solved it!
Even the country of Hans, which is the best at digging holes, the country of Little Footbath, and the country of Beauty, which can fight aliens, have not overcome the difficulties in this world.
Tertiary water-rich fine sand is a professional term.
The simple explanation is that the geological structure is somewhere between sand and dust, and was originally the product of rocks weathered by wind.
This kind of particles is extremely fine, and because the particles are very small, they are finer than flour.
Therefore, it has strong water permeability. When there are underground rivers and underground water sources nearby, a large number of water pockets containing a large amount of water will be formed in the soil layer.
This kind of water bag is a super nightmare for all constructors, designers and geologists around the world!
If you don't dig, you'll be fine. Once you dig out a water bag, it will be a disaster.
After the water bag is destroyed, the groundwater contained inside it will spurt out instantly, causing severe water inrush and mud outburst in the tunnel.
This is not the most serious.
Once the groundwater contained under the water bladder emerges, the area will be useless.
The water bladder is destroyed and groundwater gushes out, which is the result.
collapse!
Landslide after landslide, landslide again, landslide without limit!
As long as you dig it and move it, it will continue to collapse.
If you dig one bucket, it will collapse two buckets or even more to retaliate against you.
What's even more terrifying is that when it collapses, it will also spray water.
Water and mud mix together, no matter what you use
No matter how high-tech you try to fill or solidify it, it has no effect!
There is only one way to solve this world problem.
Foolish Old Man moves mountains.
Dig out all the water bladders in this area.
Otherwise, you will never think about it in this life.
However, when digging, you must ensure that the bid section does not collapse!
Once it collapses, it will involve equipment damage and casualties!
This has fallen into an infinite loop again!
This is equivalent to a person standing in a sand pit holding a spoon and constantly scooping sand. No matter how hard you try, the sand in the sand pit will not decrease at all. Until it consumes you to death.
Corresponding to myths and legends, this place is the sweet-scented osmanthus tree that Wu Gang cut down for tens of thousands of years.
So awesome, so scary.
This is what the contestants on site saw!
What I saw was different from them.
This place, in the words of tomb robbers, is a quicksand tomb where those who come and die die.
The most top-notch and most terrifying kind!
Bring all the tomb-robber ancestors with names in China from ancient times to the present and join them together, and you will be blinded!
From a Feng Shui perspective, this place is the best place to raise corpses.
The body is buried inside and will not rot for thousands of years. Not even a hair will fall out!
That’s how awesome!
So awesome!
If you can take out something from the bottom of the water bag, such as a loach or eel, then this place is a good Feng Shui treasure.
Of course, if you can pull out a big old turtle or a big tortoise, then this treasure hole will be awesome.
Unfortunately, I have just seen the whole mountain. Judging from his Dilong Shashui, there are no caves here, or even no caves.
Because the keel of this mountain has been dug out by the construction team.
Everyone has already guessed the difficult problems to be solved in the first round of assessment.
But, everyone was silent!
"The water content is 28%. It weakens when exposed to water. It is finer than flour."
On the big screen, Tang Anjun, wearing a red helmet, showed his true face, holding a handful of sand in his hand and saying with a straight face: "You are all geologists. You all know how difficult this is."
"No country or organization in the world has dug through this kind of land."
"They came and went from the Hans Kingdom. The little footbaths came and went. The people from the Beautiful Country came and went."
"We dug for three years. We also failed."
"In the past three years, all our geologists and workers in China have tried every conceivable method, but they have all failed."
