Annihilation of the solar system
Chapter 243 Pressurized water
Shen Manling said with a simple and elegant smile:
"The current meteorological conditions in the city make it impossible to observe the star rings from the ground. I have arranged for Lin Tianyu and Wu Fan to go to the suburbs with astronomical telescopes and long-range electronic control. I believe they will always leave the rain cloud coverage area and observe and To report the situation.”
The commander nodded and then looked at the meteorologist.
The slim and bespectacled meteorologist looked embarrassed. After hesitating for a while, he finally spoke:
"The causes of weather are affected by many factors such as atmospheric circulation, ocean circulation, and solar wind. Most of these factors that affect climate are chaotic systems, which makes the climate a super chaotic system.
When we were assisted by satellites, radars and supercomputers, we were not 100% sure about the causes and predictions of weather. Under current circumstances, the opinions we provide are even less accurate.
Based on what we know so far, we are not sure whether this heavy rain was caused by changes in ocean circulation or by ice that fell into the atmosphere before the heavy rain started. We still need further observation and research.
But one thing we can confirm is that the rainfall does gradually increase from the southeast to the northwest, and the chemical analysis of the rainwater shows that the composition of the precipitation is ordinary water."
"I know your difficulties, but we still have to find ways to continue the work and not relax," the commander instructed.
The next meeting was mainly about refining the plan proposed by the commander. After the meeting, several experts participating in the meeting returned to their residences in an assault boat. Due to severe waterlogging caused by consecutive days of heavy rain, any underground space was uninhabitable.
Everyone was arranged into buildings on the ground, which resulted in very tight living space. Coupled with serious communication difficulties, the Academy of Sciences and the Combat Command Center decided to gather scientists from various professions who were originally scattered everywhere into a relatively spacious building. The police station building. Therefore, their destination is the same place.
When the assault boat was approaching the police station, a collapsed hut on the roadside due to waterlogging caught Xia Lan's attention.
"Our northern city has never experienced such heavy rain. Will long-term water accumulation cause houses to collapse like that?"
The engineer on the side turned to look at the hut with only two remaining walls still exposed above the water, and said:
"This is a brick hut. It is normal for the foundation to collapse due to water intrusion. However, most of our buildings in Jinghua City are reinforced concrete structures with solid foundation piles or raft foundations. Such waterlogging will not occur unless it occurs for many years. Let it soak for a few years or even ten years, otherwise it will not have any impact on the safety of the building.
Of course, it is not accurate to say that there is no impact at all. The meteorologist just said that the rainfall here is stronger in the northwest. To the northwest of Jinghua City is Xishan, and the rainfall that penetrates into the mountain will turn into groundwater. It enters the complex under Jinghua City through underground rivers. The closed groundwater network is a supplement to the confined water.
From the perspective of bearing capacity, supplementing confined water is beneficial to the bearing capacity of building foundations. The year I started working, there was a severe drought. In addition, I did not pay attention to the protection of underground confined water in those years. As a result, there was insufficient groundwater, resulting in many subsidences in the city, and some buildings were also affected."
"According to your opinion, such heavy rain replenishes the underground pressure water and can maintain the bearing capacity of the foundation?" Xia Lan asked.
The engineer nodded:
"You can think of Xishan as a water tower. The water from the water tower is poured into the Jinghua City through the underground water network. The pressure-bearing water under the aquifer is filled and bears the pressure together with the rocks."
"Is it possible that excessive water pressure could damage the formation?" Xia Lan asked.
The engineer chuckled and said:
"This is impossible. The height of the water tower in Xishan is so high that it cannot generate much water pressure. Moreover, the sealed underground water network under Jinghua was gradually formed over tens of millions of years, and it has been highly matched with the water pressure in Xishan. It is too large.
The water pressure will be released through wells, springs or rock cracks, which will not affect the underlying bearing capacity in a short period of time."
The assault boat had arrived at the police station building, and people hurried to the lobby to take shelter from the rain. Wei Xu saw the confusion in Xia Lan's eyes.
"Sister, did you think of something?"
Xia Lan frowned slightly and shook her head slightly:
"Maybe my nerves are too sensitive. I always think of the collapse of Europa. The ice sheet more than ten kilometers thick broke away from the support of the ocean surface and immediately shattered. I also know the situation of Europa's ice sheet.
It’s completely different from the strata of Jinghua, but you have to think in that direction.”
Wei Xu shrugged:
"This is not surprising. We can't understand the tricks of alien civilizations until now. Who knows what they want to do with this heavy rain this time. Moreover, when we returned by plane, we clearly saw dense
Meteor showers fall over the cities along the way.
This shows to a certain extent that the ice and organic life on the star ring are the fundamental cause of this heavy rain, but there is nothing in the chemical and biological random sampling report of the rainwater."
The meteorologist wiped off the water droplets on his glasses and put them back on:
"Ice coming down from low-Earth orbit will increase the humidity of the atmosphere, which does help rainfall. But our atmosphere itself is rich in moisture, coupled with the completely chaotic ocean circulation after the polar ice caps melt. All of these may
It is the cause of abnormal rainfall over the city.
Although the super chaotic system of climate cannot be predicted and controlled at the level of human science and technology, this is not necessarily the case for alien civilizations. If my hypothesis is true, then only a small part of the current rainfall comes from Europa.
Ice cubes and smaller parts may contain alien organic matter.
Coupled with the incomplete randomness of our sampling and the insufficient number of samples under the current circumstances, our rainwater sample analysis results may not be representative of true random sampling."
Wei Xu nodded solemnly:
"In this way, the water that will eventually flow into the ground may be more valuable for analysis. Anyway, senior sister also has doubts about the confined water, so we might as well try sampling and analyzing the groundwater, especially the confined water!"
The meteorologist pointed to the dirty water in front of the building:
"We have already sampled surface stagnant water and shallow surface water. The samples have long been contaminated and have no analytical value. The pressurized water environment is closed, and maybe we can get something useful."
Everyone turned their attention to the engineer, who looked embarrassed:
"This was not difficult in the past. Just find a deep well or ask the geological survey team to drill a well and drill through the water-proof rock formation. But now, it is difficult for the geological survey team to find both people and equipment at once, and Jinghua
There have long been no drinking water wells in the city..."
Having said this, the engineer rolled his eyes and thought of something.
"There may be a place where you can get samples of pressurized water!"
"Where?" everyone asked curiously.
Engineering looked around at the people around him and said hesitantly:
"North Bridge...Suolongjing next to North Bridge."
"Lock Longjing?" Everyone exclaimed.
The engineer had a blush on his face.
"Suolongjing, which has a strong legendary color among the people, is actually an ordinary water well with a pressurized water spring in our eyes. The iron chain thrown from the wellhead just seals the pressurized water spring formed by the cracks in the aquitard layer. Time
As time goes by, rust and mud get mixed together.
Pull the iron chain mixed with rusty mud again, and the pressurized water in the spring will overflow. Naturally, dark red mud will surge, accompanied by a fishy smell. Moreover, such wells are generally large and deep, and the pressurized water rushes out of the sharp point.
When the whistling sound passes through the resonant cavity of the well shaft, it will feel like the roar of a dragon.
The combination of these various characteristics makes it easy for people to have daydreams in the old society where people had a low level of education. But the so-called 'Longjing Suojing' is indeed just an ordinary well on a pressurized water spring."
"Then let's go to Suolongjing in Beiqiao!" Wei Xu shouted excitedly.
"The Longjing lock in North Bridge was demolished long ago when the subway was built, but I do know that there is another place in Jinghua that has a Longjing lock." Zhou Cheng said as he walked out of the aisle with Cao Rui.
"Oh, I didn't expect you, Lao Zhou, to research these things!" Cao Rui said with a smile.
Zhou Cheng said angrily:
"I don't know how to study! Before the crisis era, I had a group of buddies who played off-road vehicles. You have all seen them. They all drove old cars. They often went to the auto parts city to buy parts. I went there more often and sold parts there.
The boss became familiar with her.
I heard them say that in the square of the auto parts city on the West Fifth Ring Road, there is a Suolongjing left over from the Qing Dynasty. I have also seen it. It is a manhole cover carved with dragons, phoenixes, and scriptures, but I have not opened it.
.”
The engineer nodded repeatedly:
"Yes, yes, I heard the teacher say that in addition to the Beiqiao one in Jinghua City, there is also a Suolongjing in the west. My colleagues and I also looked for it at that time, but unfortunately we couldn't find it. The location is close to the place Professor Zhou mentioned. If Beiqiao
That one is gone, you can go and have a look!”
