In many places where landslides occur, there are blocking nets, commonly known as mountain protection nets, which are generally composed of high-strength, corrosion-resistant metal or polymer materials, which are very versatile.

Protective nets are used in almost all mountain road construction, and they require different strengths, especially in Yuzhou, where such things can be bought everywhere.

"I took a look," Pang Hongshan said: "If verification is needed, further excavations in this neighborhood are needed."

"Didn't this have already dug up a lot of soil?" Bai Song was a little puzzled, why he still needs to dig further.

"Section Chief Bai," Pang Hongshan said.

Bai Song heard Pang Lao call him, and immediately understood what was going on.

Professional matters are left to professional people, and he said that these are true lay comments.

"What excavation equipment is needed? What size excavator?" Bai Song immediately changed his tone.

"You don't need an excavator, you need..." Pang Hongshan looked around: "You need 10 to 15 workers, just a pickaxe and a shovel."

"This is simple and too simple", the local leaders who accompanied him immediately began to make arrangements.

The workers came very quickly. There were almost 20 workers, each with their own guys.

The dialects of these people are relatively heavy, and Old Pang can't understand them. Two policemen are here to help with the translation, and the excavation progress is very fast.

Old Pang also found a shovel, and he did it himself. As much depth as he digs, other people will dig as much depth nearby. Not only that, he also became a supervisor.

These workers worked very quickly. In less than an hour, they dug to the depth that Old Pang needed, so they let them go first. The local responsible comrade went to check out and sent the people away.

The main body of this mountain is a layer of rock. After digging so much soil, it is all stones and can't be digged.

"Look," Pang Hongshan also respected Baisong because of Baisong's previous proposal: "Although the excavator has dug away the extra soil, it can still be determined that this area of ​​the head sees more water than other places. Much larger. There is no significant difference in the terrain around here, so the amount of water seepage difference must be man-made."

"Can pouring water in advance cause landslides?" Bai Song didn't understand.

"Of course it won't work, but it depends on how the water is added in. It's just that if the pouring water fails to achieve the effect, you can use high-pressure equipment to hit the water deep," Pang Hongshan said: "There is no trace of explosives used throughout the process , But the abnormal water seepage in the upper edge area is very obvious. If we expand the search range, we should be able to find traces of the fixed mountain protection net. The level of the protection net he uses will not be too low, and the required fixed piles will definitely be driven. Is deeper."

"Don't fetch water from the high-pressure device?" Bai Song measured it with his hands: "Is this a small machine?"

"Impossible," Pang Hongshan said: "If you want to create such a landslide, although the terrain itself can form the conditions, it still needs more professional equipment."

Pang Hongshan stepped back, roughly estimated the terrain here, and pointed to five directions: "These five places are the most suitable for fixing net piles."

Among the five places that Pang Lao pointed out, Bai Song couldn't see any of them, but the others here also understood what they should be doing at this time, and they all started to take action.

And Pang Hongshan himself, still holding a small hammer, continued to look for traces.

"Is this person very professional?" Bai Song asked, "Pang, according to your experience, what kind of professional level is needed to be able to achieve this level?"

"Not necessarily", Pang Hongshan shook his head: "I do more theoretical research. Let me give you an example, you are in this kind of place, as if now, many places have been dug into the rock layer, you can see the beauty here. ?"

"Not so good." Bai Song doesn't understand what these broken rocks are. Although the colors are different, they are all rocks.

"Look here, the upper part of this stone, this is a layer of leopard skin-like dolomite limestone... well... you may not understand it, but the iron sandstone here is very interesting, here is a weathering The crust, the weathering crust between these two rock layers, is caused by the'Qinyu Movement' that is not easy to see in geology. This small layer represents 20 million years." Pang Hongshan took the geological hammer and knocked casually. Knock: "It's very common in the east, but it's not common here."

"2000, ten thousand years?" Bai Song was taken aback for a moment.

"Well, and this crustal movement happened one billion years ago. If we don't dig so deep this time, we might not see such a beautiful place...Of course, most people don't know this kind of beauty, I think, The person who designed this did not understand it, but it really hit the water to such a deep level. The engineering level here is higher than mine.” Pang Hongshan no longer popularizes science: “Although I am not an expert in construction, but I also understand that this person is likely to specialize in the maintenance of roads and bridges. According to my personal thoughts, this old way of doing things does not seem to be done by young people."

The theoretical level and the construction level are two different things. A senior engineer may not know how to mix concrete better than an ordinary migrant worker.

"Then..." Bai Song was about to ask, but someone shouted and found a buried steel pile ~lightnovelpub.net~ was already underground, and it had been covered with a layer of soil if it rained. It is impossible to find it without looking around very carefully.

Hearing this, Pang Hongshan immediately got up and walked over there, Bai Song hurriedly followed.

The **** here is relatively large. Pang Hongshan was old and spent a long time squatting on the ground. Suddenly, he suffered from insufficient blood supply to his brain, and he staggered and was about to fall. Fortunately, Bai Song moved quickly and quickly passed by to stand firmly and support. Pang Lao helped him up slowly.

Just now when Pang Lao pointed out five directions, Bai Song also wanted to look for it, but he still stayed here because he was afraid of such a thing.

"Thank you," Pang Hongshan rubbed his temples and smoothed his chest: "I'm getting older..."

Having said this, Pang Hongshan looked at the steep **** here, the soil has been dug away, and all the rocks are exposed. If he rolls down from here, he will be in trouble at his age!

"I'm okay." Old Pang closed his eyes vigorously and shook his head a few times: "Fortunately for you, it's good to be young."

"You are polite, I will help you over," Bai Song said.

…

This is a steel nail that has penetrated into the soil. Only this steel nail can determine one thing: Lin Liang's death must be man-made.

If you find this one, there must be at least one more.

"Check the tensile strength of this anchor, destructive inspection, check the construction method and construction machinery." Bai Song gave an order: "Immediately file a case, and it is not yet certain that it is against Lin Liang. The cause of the case is the crime of endangering public safety by dangerous means. ."
