Chapter 379: Pipeline construction

Because they already have the experience of building the first heating hub, when the second heating hub was built, both Chen Xin and Cao Daren learned relevant experience and improved the construction process to allow the second heating hub to be heated. The construction of the hub has become smoother.
For example, when building the first heating hub, Chen Xin and the others dug out the snow and laid the foundation underground before beginning the assembly of the heating hub. But when building the second heating hub, They did not do so.
Instead, the heating hub is assembled while digging downwards. After the pit is dug, the equipment is assembled, and it only needs to be fixed to the foundation.
This construction method undoubtedly saves a lot of time. Although the installation period of a heating hub is not long, it is always good to save some time.
The workers were under intense construction, and Wang Hai led his combat team to spread out around and set up guards. Chen Xin and Cao Daren were discussing the next construction plan.
The two heating hubs are now considered to be built, but under the two heating hubs, one is a pumping well and the other is a return well. If they want to perform their respective functions, they need to be laid between the two towers. Pipes to re-inject water from the pumping well into the ground through the return well.
However, the laying of this pipeline is a troublesome thing.
First of all, the bottom of the heating hub is at the original height of the ground, which means that they are more than ten meters shorter than the current snow surface.
The laying of pipelines needs to be close to the ground, not on the snow. After all, the heating hub will melt the surrounding snow. The snow itself may also be affected by natural factors such as wind and temperature. Not stable enough.
And this also means that the pipeline between the two heating hubs must be drilled under more than ten meters of snow before construction can be carried out.
As for digging up the snow, Chen Xin rejected the plan without even thinking about it. It would not be worth mentioning that the amount of construction was too great.
The distance between No. 7 Middle School and the railway station is not too far, and the terrain is relatively flat. If you want to lay a pipeline, it is very simple without snow.
But once a dozen meters of snow is added as a prerequisite, simple construction will become very troublesome and difficult.
"Although it is feasible for workers to dig holes, it is too inefficient and too slow. Although it does not seem to be far away, the digging will not be completed within ten and a half days after the digging! This is too time-consuming." Cao Daren took the map, measured the distance between the seventh middle school and the train station on it, frowned and said to Chen Xin.
Chen Xin also nodded. For such a long distance, even if you want to lay a pipeline before the disaster, it will take several days to construct. Now you still need to dig a hole under the snow that is more than ten meters deep, even if it is snow. Dig better than the soil, but it is not an easy job. The inefficiency can be imagined.
"But no matter what happens, this pipe must be laid! Even if workers were to dig by hand in the end, they would have to be dug." Chen Xin first set the tone for this matter, and then said to Cao Daren: " Are there other simpler construction methods? For example, melting snow, or using tools to save time?"
"Then unless it's a shield machine, but where can I get a shield machine like this in a small place like the city? Things that are not available in the city can only be obtained by the provincial capital, and now even if you can get it, still I don't know if it can be shipped." Cao Daren still knows about the shield machine, but he feels unrealistic. This kind of large-scale equipment specially used for underground drilling is not so good.
"A shield machine? If you really want it, it's not impossible to get one..." Chen Xin knew that if he needed it, he could get it as long as he opened his mouth, but this was not Chen Xin's first choice.
It wasn't that Chen Xin was hypocritical, but he felt that it was just laying a pipe under the snow, and there was no need to use large equipment such as a shield machine.
They are not trying to build a subway, nor are they facing any hard rock formations, but snow. If the snow is not more than ten meters thick, and he also wants to shorten the construction period, let workers dig by hand. .
Insert a sentence, [\Mic\Mic\Reading\app\\] really good, it is worth installing, after all, there are many books, all books, and fast updates!
It is necessary to know that a shield machine costs tens of millions. It can be used to dig while laying pipes. It is a real overkill to deal with snow.
Cao Daren didn’t know what Chen Xin was thinking. He said that he couldn’t get a shield machine. He was a little surprised: "Writer, don’t you really want to get a shield machine? That’s too wasteful. It’s better to find a few more workers to work separately to increase the efficiency of the shield machine!"
"This is also a way, but is there no better way?" Chen Xin can certainly think of it to improve efficiency in segmented construction. This is also a practical solution, but Chen Xin still thinks There should be a simpler way.
However, he is not a stubborn temper. He didn't think of a suitable method but didn't force it. So he said to Cao Daren, "Since I can't think of a good method now, I can only use the method of construction in stages. I will contact you later. The staff in the city, see if they can send us some more workers."
"Okay, as long as there are enough manpower, I can guarantee that the task will be completed on time according to the quality and quantity!" Cao Daren agreed and assured Chen Xin, patting his chest.
This kind of thing is actually simple and simple. As long as there are enough manpower to construct in sections, it is not difficult to save time.
It’s just that Cao Daren looked at the special forces guarding around him and couldn’t help but ask Chen Xin:
Writer, can these soldiers come and help? I think they all have exoskeletons, and they must work more smoothly than ordinary workers. If they help, then our construction will be much faster!"
"These are all special forces. They are different from ordinary soldiers. Besides, people are here to protect me, so I can't ask them to help with the construction!" Chen Xin shook his head and rejected Cao Daren's idea.
"In this way, you can only rely on ordinary workers. I really envy them for having exoskeletons. That thing is a magical tool for work!" There is no regret in Cao Daren's words, looking at the exoskeleton on the special soldiers next to him with envy.
Seeing him like this, Chen Xin couldn't help but smile, and smiled at him: "If you are really envious, I will look back and find a way. The shield machine can't be obtained, and a few sets of exoskeletons are fine."
When Cao Daren heard Chen Xin say this, his face also showed a surprised expression: "That feeling is good! If there is an exoskeleton, the worker's work efficiency can at least double!"
