Happy Little Mayor

Protecting the firefly cave is imperative. After Wang Bo blocked the opening, he immediately arranged for the uncle Bing to contact the technology company to set up a surveillance camera at the entrance.

To protect this cave, it is necessary to understand the cave. Porter is still in this area. His construction company is not just a construction team, which has experts in geological exploration and topographic research.

Just like gold prospecting, experts also issued a report covering the specific conditions of the mine.

Potter sent in personally and handed a small book to Wang Bo, and he sighed, "You are right, this cave is so beautiful that it is unthinkable. My guys and I were shocked at first sight. Now. "

Exploration holes must be inspected. Wang Bo approves that engineers can enter the cave, but can only take test samples and then come out for testing. It is not allowed to turn on lights and start work inside.

Wang Bo opened the report book and asked, "Your speed is really fast."

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

Potter laughed: "Because we are professional, but seriously, I really want to stay in it for a few more days, they are so beautiful, especially when we go to fetch water, we are on the water, as if we have come to Xinghe."

Having said that, he shook his head strangely: "I have seen the Firefly Cave. Why don't other holes have such amazing views?"

Wang Bo is studying caves these two days. He knows the reason, saying: "Because our caves have not been destroyed by external forces since its birth, this is a complete original ecology. What about other caves? The lights are shining, the flames are burning, and there are even Trash is thrown in, they have been destroyed, severely damaged. "

This is why he carefully protected it from the beginning. The principle of environmental protection is first. If you do n’t know how to protect it, do n’t touch it.

Next, Potter introduced him to caves. To protect mushroom flies, we must start by protecting their living environment.

"This cave is made of limestone. Like other limestone caves in New Zealand, it is formed from the fossils of countless marine life remnants."

"If you understand the history of the North and South Island of New Zealand, you know that 30 million years ago it was under the deep sea. Then 24 million years later, the area where the karst caves have undergone numerous geological changes, such as crustal changes and Volcanic activity, etc., many hard limestones were distorted and brought to sea level. Afterwards, they were eroded by rain to form what is now a cave. "

"You know, rainwater and air carry slightly acidic carbon dioxide, which accumulates over time, causing the crevices to gradually expand into stalactites and stalagmites, which is the scenery of the Firefly Cave we see today."

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

Wang Bo nodded: "It took so long to form stalactites in the cave!"

"Time is not the most important, the most important are some coincidences. For example, two stalactites side by side will have different formation speeds because of different water flow paths, and then they will form some strange shapes together." Potter Explained.

"What about our caves?" Wang Bo asked.

"This karst cave is a very rare active rock cave. Testing the rocks in different areas, through carbon 14 detection, it is concluded that the cave was formed 15 thousand years ago."

Having said that, 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. The water from the cave flows down from the lake. "

"My folks have inquired about the evolution of the terrain in this area. It is estimated that there was a small lake here that was adjacent to Lake Hawea but closed.

"At first, this small lake was frozen by ice. Later, due to the climate change, the snow and ice gradually receded, flowing into the cracks of the calcareous rock layer below, and gradually eroded into a cave."

"You must not 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 years or 20,000 years. Its top wall will eventually become very thin and it cannot stand the pressure of the lake. Then Fragmentation, the cave will eventually become part of Lake Hawea. That's why I said this cave is an active cave, and it has life. "

Wang Bo said: "Now the pressure on the top wall is okay? I don't care about 10,000 years or 20,000 years later, I care about a year or two later!"

"Because the scale of the survey was limited, we did not study every corner of the cave. We just checked it with an echometer and a radiometer. Now the pressure on the top wall is not much compared to the stone wall and there is no danger. Potter laughed.

In this way, Pharaoh was assured that such a beautiful cave would need to become a pearl in the history of the world's landscapes, but it could not disappear in the long history without shining.

The report now issued is only a preliminary report, and exploration will continue in the later stage. The cave tourism industry has high requirements for exploration qualifications, otherwise there will be a problem caused by collapse, and there will be no tourists in it.

Later, Wang Bo and Potter negotiated. The cave extends toward the lake, so it does not hinder the construction of the runway around the lake. He meant to continue to build the runway, but there is no lane here, and bicycles and cars are not allowed to enter.

Porter said it was okay. He suggested building an all-wood runway, that is, a runway around the northeast of the lake. After weeding and laying the ground, a layer of wood runway was laid on it.

Wood has excellent strength and vibration conductivity. In this way, when people step on the floor when they run, the impact force is diffused by the wooden 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 of their feet on the ground is not enough to affect the cave wall, but when many people run, they will have resonance. If the vibration wave is transmitted to the cave through the stone, it will affect the life of the mushroom fly.

Mushroom fly larvae cling to the stone wall to survive, they mainly rely on the vibration of the spit out of the screen to determine the presence of food, and then go to prey.

So for them, the vibration wave has a great effect. Once there is a wave entering the cave, they will mistakenly think that there is food coming in and then searching, and extra energy is consumed.

The preliminary construction plan was released, and Porter took the plan back and asked the experts to conduct research and research. Wang Bo's attitude towards the cave is: only if it can be protected can it be developed, if it cannot be determined, then it will not be developed! (To be continued.)
