Ten o'clock in the evening.

Gu Kaiwen is exercising in his daily crunches, although Boss Gu has such a magical thing as the mutated Morinda Heaven, he still likes to exercise, so as to gain a stronger physique.

If you don't have a strong physique, what's the use of even if the small Kaiwen is strong?

Do you have to ask Yao Feifei to join the army and eventually become a female captain?

Excuse me!

Anyway, Boss Gu prefers the active way and refuses to passively accept.

At more than eleven o'clock in the evening, Gu Kaiwen's WeChat received a message from Sun Fei, and Sun Fei sent a lot of pictures, including infrared thermal radiation pictures, as well as pictures of ultrasonic detector feedback.

The thermal radiation images taken by the infrared thermal detector show that three new heat sources have been added in addition to the heat source photographed by Ma Zhiming.

Judging from the information fed back by the infrared thermal detector, the three new heat sources have a core temperature of only 26 degrees, which can only be judged on a cool night.

According to the feedback from the ultrasonic detector, the three new heat sources also have a cavity area underground, even if the cavity area is very small, only two or three cubes, but it shows that there is also a corruption reaction underground.

Gu Kaiwen sent a WeChat message to ask, 'What's the situation?'

After Gu Kaiwen sent WeChat, in less than a minute, Sun Fei's phone called, and he asked first, "Boss Gu hasn't slept now, has he?"

Gu Kaiwen responded affirmatively, "Well, I haven't slept yet." Brother Sun, what's the situation in the picture just now, three new heat sources have been added?"

"Yes!" Sun Fei quickly responded, "We have fully probed the situation of the Ansheng landfill, a total of four heat sources, and no more heat sources have been found." ”

"Is there a big problem with the images of those ultrasonic detectors?" Gu Kaiwen asked again.

When he just looked at the images obtained by the ultrasonic detector, Gu Kaiwen found that the concrete structure in the image was not only thin, but also had cracks.

"There is a big problem. Sun Fei sighed, "Although from my standpoint, I shouldn't say too much, but I have to say that these people are too bold!"

"Huh?" Gu Kaiwen didn't understand what Sun Fei meant.

"Teacher Zhu just probed, he was scared into a cold sweat, the safety hazards of this Ansheng landfill are very serious, if left unchecked, at least three months, at most half a year, there will be a big accident. Sun Fei said nervously.

"What's wrong?" Gu Kaiwen frowned.

"Teacher Zhu has made a preliminary judgment of the situation of the No. 1 hollow. By the way, Cavity No. 1 is the Cavity you discovered, and it's the largest underground cavity. Sun Fei explained.

"What's the specific situation with that No. 1 hollow?" Gu Kaiwen asked.

Sun Fei explained in detail, "The situation of the No. 1 cavity is very serious, and the results of Ma Zhiming's previous detection are indeed inaccurate, and the scope of the No. 1 cavity is larger than that he detected. After our detailed exploration, the surface hanging area of Cave No. 1 has exceeded 40 square meters, the depth has exceeded 6 meters, and the total volume has exceeded 250 cubic meters. ”

"To make matters worse, the concrete layer in the suspended area is only 39 centimeters thick, the steel content is very small, the concrete is not up to standard, and there are cracks that are more than 15 centimeters long. ”

"Fortunately, there are very few people in this ecological square, and if there are more than 40 people in the suspended area, I am afraid that the suspended area will collapse. Sun Fei said a little happily.

Gu Kaiwen is also apprehensive, there is no problem with the ecological park of Ansheng landfill, thank God.

"By the way, has the internal gas composition of Cavity No. 1 been detected clearly?" Gu Kaiwen asked about the key thing.

Sun Fei responded affirmatively, "Basically, it has been detected, and in general, there is no big problem, the air inside the No. 1 cavity is preliminarily judged to be a mixture of methane and carbon dioxide, and there are very few other components." However, the specific situation needs to be further analyzed. ”

"So the problem of No. 1 Hollow is easy to solve?" Gu Kaiwen asked tentatively.

"Barely a big problem. The only trouble is that the gas pressure inside Cavity No. 1 is relatively high, which has reached 4 standard atmospheres, but these are troubles that can be controlled. Sun Fei responded.

Gu Kaiwen breathed a sigh of relief, "Then what help do you need to solve this problem?"

"Haha, it only takes a little!" Sun Fei said jokingly, "We are professionals, and Boss Gu only needs to pay to solve all problems." ”

"How much does it cost?" Gu Kaiwen just got two rewards, now is the time to be high-spirited, since the problem of Ansheng landfill has already given Gu Kaiwen a reward in advance, of course Gu Kaiwen will not be stingy.

"Teacher Zhu has just made the budget, and to solve the problem of the first step, first release the gas pressure inside the No. 1 cavity, which only needs 300,000 yuan. Sun Fei responded.

Gu Kaiwen was a little flustered, is it so cheap?

Sun Fei seemed to guess Gu Kaiwen's thoughts, and he asked with a smile, "Are you sighing, why is it so cheap?"

Gu Kaiwen laughed dryly, "It's really cheap!"

"Mr. Zhu is a well-known expert in China, and he will definitely not bully laymen in terms of engineering quotations, which you can rest assured. In addition, this budget offer only solves the gas inside the No. 1 cavity, and does not solve all the problems of the No. 1 cavity. Sun Fei explained for Gu Kaiwen.

Later, Sun Fei added, "Another thing to note is that this offer is limited to solutions with carbon dioxide and methane gas mixtures. I wish the teacher to open a window to check first, if the window is opened and the internal gas composition is found to be too toxic and harmful, it will increase the budget, no problem, right?"

"No problem!" Gu Kaiwen responded, "When will Teacher Zhu start to solve it?"

"It's not going to work today, we haven't had dinner since we started at noon, so we have to rest for at least one night today and start work tomorrow morning. Sun Fei responded.

Gu Kaiwen was a little speechless, he complained, "Do you work so hard?"

"Nonsense!" Sun Fei snorted, "Who made this place so bad, aren't we worried about something happening!"

Gu Kaiwen remedied, "Thank you, by the way, Brother Sun, my side will guarantee your food expenses in full, and you can eat as much as you want." ”

Sun Fei responded with a wicked smile, "Boss Gu is magnificent, the time is not early, I won't disturb Boss Gu to rest, and I will report to Boss Gu after there is a situation tomorrow." ”

"Okay. Gu Kaiwen responded and ended the call.

After putting down his phone, he breathed a long sigh of relief, at least now that the problem of the Ansheng landfill is being solved, everything is going in a good direction.
