785.Overview of the Cave (1/5)

It is imperative to protect the firefly cave, and after Wang Bo blocked the entrance of the cave, he immediately arranged for Uncle Bing to contact a technology company to set up a surveillance camera at the entrance of the cave. Pen % fun % Pavilion www.biquge.info

To protect the cave, you need to know about the cave, and Potter is still a good at it, and his construction company is not just a construction team, but also has experts in geological exploration and topographic research.

Just like gold exploration, experts have issued a report on the specifics of the mine.

Potter personally sent it and handed a small notebook to Wang Bo, and he sighed: "You're right, this cave is so beautiful that it's unimaginably beautiful, and my guys and I were stunned at the first sight of it. ”

Wang Bo approved that the engineers could enter the cave, but they could only take test samples and come out for testing, and were not allowed to turn on the lights and start work inside.

Wang Bo opened the report book and asked, "You guys are really fast." ”

It took more than 10 days for the gold exploration report to come out, and the report took only two days.

Potter laughed, "Because we're professionals, but seriously, I'd love to stay in there for a few more days, they're so beautiful, especially when we go to fetch water, it's like we're in a galaxy." ”

Speaking of this, he shook his head strangely: "I've seen the glowworm cave, why don't other caves have such amazing beauty?" ”

Wang Bo has been studying the cave for the past two days, and he knows the reason and says: "Because our cave has not been destroyed by external forces since its birth, it is completely original. What about the other caves? The lights are shining, the flames are scorching, and even the garbage is thrown in, and they have been destroyed, badly damaged. ”

That's why he was careful to protect it from the beginning, the first principle of environmental protection, if you don't know how to protect it, then don't touch it.

Next, Potter introduced him to the cave, and to protect the mushroom flies, he had to start by protecting their living environment.

"The cave is made of limestone, and like other limestone caves in New Zealand, it was formed from fossils of countless remnants of marine life."

"If you know the history of New Zealand's North and South Islands, you know that 30 million years ago it was under the deep seabed, and over the course of 24 million years, the area where the cave is located has undergone numerous geological changes, such as crustal changes and volcanic activity, and many of the hard limestone rocks have been twisted and deformed and brought to sea level, and then eroded by rain to form the current cave."

"You know, the rain and the slightly acidic carbon dioxide in the air have been eroded over time, causing the crevices to expand into stalactites and stalagmites, which is the view of the glowworm cave we see today."

"According to the calculations of our experts, it takes about 100 years to form a 3 cubic centimeter stalactite, but it will also affect the speed of stalactite formation due to the topographic structure, plant function, limestone depth, internal and external environmental climate, and the number of years of cave formation."

Wang Bo nodded and said, "It turns out that it takes so long for the stalactites in the cave to form!" ”

"Time is not the most important thing, the most important thing is some coincidences, such as two stalactites side by side will have different formation speeds due to different water flow paths, and then they will form some strange shapes together." Potter explained.

"Where are our caves?" Wang Bo asked.

"This cave is a very rare active rock cave, and the rocks in different areas have been examined, and through carbon-14 testing, it is probably concluded that the cave was formed 15,000 years ago."

Speaking of this, Potter said, "Oh, I forgot to tell you the most important news, the bottom of the cave is under the lake, and above its head is the bottom of Lake Hawea, and the water of the cave flows down from the lake. ”

"My men have looked up the history of the topography of this area, and they estimate that there was originally a small lake here, adjacent to Lake Hawea, but closed and isolated."

"This small lake was frozen at first, but then the ice and snow gradually receded due to climate change, and flowed into the cracks in the calcareous rock layer below, gradually eroding into a cave."

"You won't believe it, this cave is still very young, it will continue to expand, and if no one interferes, it may be another 10,000 or 20,000 years, and its top wall will eventually become very thin, and it will not be able to stand the pressure of the lake, and then it will crumble, and the cave will eventually become part of Lake Hawea. That's why I just said that this cave is an active cave, and it still has life. ”

Wang Bodao: "It's okay to be under pressure on the top wall now, right?" I don't care about 10,000 or 20,000 years from now, I care about a year or two from now! ”

"Because the scale of the survey was limited, we did not study every corner of the cave, but only checked it with an echometer and a radiograph, and now the pressure on the top wall is nothing compared to the stone wall, and there is no danger." Potter laughed.

In this way, Lao Wang can rest assured, such a beautiful cave, it needs to become a pearl in the history of the world's scenery, but it can't disappear in the long river of history without shining light.

Now the report is just a draft report, and the exploration will continue in the later stage, and the cave tourism industry has high requirements for exploration qualifications, otherwise there is a little problem that will lead to collapse, and the tourists in it can not run away, the whole pot end!

Subsequently, Wang Bo and Porter negotiated that the cave would extend in the direction of the lake, so it would not hinder the construction of the runway around the lake, and he meant to continue to build the runway, but there would be no lanes on this side, and bicycles and cars would not be allowed to enter.

Potter said that was fine, and suggested building an all-timber runway, which would be a log runway around the northeast of the lake, with weeds cleared and the foundation laid.

Wood has excellent power and vibration conductivity, so that when people run on the floor, the impact generated by the impact is diffused by the board, which can effectively reduce the damage to a place on the ground.

The purpose of this is naturally to protect the cave.

It may be that the impact of people's feet on the ground when they run is not enough to affect the stone walls of the cave, but when many people run, there will be resonance, and if the vibration waves are transmitted to the cave through the stones, it will affect the life of mushroom flies.

Mushroom larvae cling to the stone walls, and they mainly rely on the vibration sensation generated by the spitting out of the silk mesh to determine whether food is present, and then go to hunt.

Therefore, for them, vibration waves have a great impact, once there is a fluctuation into the cave, they will mistakenly think that there is food to come to the door and go to search for it, which consumes additional energy.

The preliminary construction plan was released, and Porter took the plan back to let the experts conduct research and verification, Wang Bo's attitude towards the cave was: if it can be protected well, it can be developed, if it cannot be determined, then it will not be developed!
