Chapter 800 785. Overview of Karst Caves (15)

It is imperative to protect the firefly cave. After Wang Bo blocked the entrance of the cave, he immediately arranged for Uncle Bing to contact the technology company to set up a surveillance camera at the entrance of the cave.

To protect this cave, one must understand the cave, and Potter is good at this. His construction company is not just a construction team, there are experts in geological exploration and terrain research.

Just like gold prospecting, experts also issued a report to report the specific situation of this mine.

Porter delivered it in person, and handed a small notebook to Wang Bo. He sighed and said, "You are right, this cave is so beautiful that it is unimaginable. My friends and I were shocked when we went down to see it at first sight." gone."

Exploration mines must be inspected. Wang Bo approved engineers to enter the cave, but they can only take test products and come out for testing. They are not allowed to turn on lights or start work inside.

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

It took more than ten days for the gold prospecting to report, but this report only took two days.

Potter said with a smile: "Because we are professionals, but to be honest, I really want to stay in there for a few more days. They are so beautiful, especially when we go to fetch water, being on the water, it seems to be in the galaxy."

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

Wang Bo has been studying caves for the past two days. He knows the reason and said: "Because our caves have not been damaged by external forces since their birth, this is a completely original ecology. What about other caves? Lighting, flames, and even Garbage thrown in, they've been damaged, horribly damaged."

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

Then Potter introduced him to the cave. To protect the mushroom flies, we must start by protecting their living environment.

"The cave is limestone, and like other limestone caves in New Zealand, it is formed from the fossilized remains of countless marine organisms."

"If you know the history of New Zealand's North and South Islands, you will know that 30 million years ago it was under the deep sea. In the next 24 million years, the area where the caves are located has undergone numerous geological changes, such as crustal changes and Many hard limestones were distorted and deformed by volcanic activities and brought to sea level, and then eroded by rainwater to form the current cave."

"As you know, the rainwater and air contain slightly acidic carbon dioxide, which erodes over time, causing the rock cracks to gradually expand into stalactites and stalagmites. This is the view of the Firefly Cave we see today."

"According to the calculations of our experts, 3 cubic centimeters of stalactites can be formed in about 100 years, but the speed of stalactite formation will also be affected by the terrain structure, plant function, limestone depth, internal and external climate, and the number of years the cave was formed. "

Wang Bo nodded and said, "It turns out that the formation of stalactites in the cave takes so long!"

"Time is not the most important thing. The most important thing is some coincidences. For example, two side-by-side stalactites have different formation speeds due to different water flow paths, and then they form some strange shapes together." Porter explained.

"What about our cave?" Wang Bo asked.

"This cave is a very rare active rock cave. After testing rocks in different areas, 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 the top of it is the bottom of Lake Hawea, and the water in the cave flows down from the lake. "

"My buddies have inquired about the evolution history of the terrain in this area. It is estimated that there used to be a small lake here, which is adjacent to Lake Hawea but is closed."

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

"You will never believe that this cave is still very young, and it will continue to expand. If there is no human intervention, it may take another 10,000 to 20,000 years. Its top wall will eventually become very thin and cannot withstand the pressure of the lake. Then Fragmentation, the cave will eventually become part of Lake Hawea. That's why I just said this cave, it's a living cave, it still has life."

Wang Bodao: "Is the pressure on the top wall okay now? I don't care about ten thousand or twenty thousand years from now. What I care about is one or two years later!"

"Because the scale of the survey was limited, we didn't study every corner of the cave, but just checked it roughly with an echometer and a ray meter. Now the pressure on the top wall is nothing compared to the stone wall, and there is no danger. ’ laughed Potter.

In this way, Lao Wang can rest assured that such a beautiful cave needs to become a pearl in the history of world landscapes, and it cannot disappear into the long river of history without shining its light.

The current report is just a draft report, and the exploration will continue in the later stage. The cave tourism industry has high requirements for exploration qualifications, otherwise there will be a problem that will lead to the collapse, and none of the tourists inside will be able to escape.

Afterwards, Wang Bo negotiated with Porter that the cave extended towards the lake, so it would not hinder the construction of a runway around the lake. He meant to continue building the runway, but there was no lane here, and bicycles and cars were not allowed to enter.

Porter said that was no problem. He suggested building an all-wood runway, that is, after clearing weeds and laying a good foundation, a runway of wood was laid on top of the runway around the northeast of the lake.

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

The purpose of doing this is naturally to protect the cave.

Maybe when people run, the impact force of their feet on the ground is not enough to affect the rock wall of the cave, but when many people run, resonance will occur. If the vibration wave is transmitted to the cave through the stone, it will affect the life of the mushroom fly.

Mushroom fly larvae live close to the stone wall. They mainly rely on the vibration produced by the spit out silk screen to judge whether there is food, and then go to prey.

Therefore, for them, the vibration wave has a great influence. Once a wave enters the cave, they will mistakenly think that there is food coming and search for it, consuming extra energy.

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