Doomsday Bunker Upgrade Chapter 382: Jumping method
Chapter 382 of the main body of the jacking method
Because the pipeline construction needs to avoid the buildings on the ground, and considering the influence of factors such as thermal expansion and cold contraction, the pipeline cannot be pulled into a straight line, and an elbow must be set in the middle.
So in the process of construction, how to install the elbow and how to deal with the construction problem of changing the direction of the pipeline after the installation of the elbow has become a problem that Chen Xin must consider.
The installation of the elbow itself is easy to say. It’s a big deal to dig a shaft from the ground and put it down. Although it requires a certain amount of work, it is still easy to complete. As for how to weld, Chen Xinda can use a mechanical arm of power armor to do it. .
However, how to put the pipeline down after the pipe line changes direction is a problem that makes Chen Xin scratch his head.
In the past, if you wanted to lay a pipeline, if it was not directly placed on the ground, the most common method used by the construction party was to excavate the entire ground for construction, and then cover it with soil backfill after completion.
Chen Xin can of course also use this method, but correspondingly, he can dig up more than ten meters of snow, just to put down the pipeline, unless there are hundreds of people equipped with exoskeletons on Chen Xin. Workers, and there are a lot of construction machinery, otherwise it is not suitable for such a huge construction method.
And if Chen Xin wants to use this method for construction, he doesn't need to be a small shield machine.
Facing this question, Chen Xin did not scratch his head by himself, but found Cao Daren and asked him if there was a suitable method.
After all, Chen Xin was only a writer who wrote online novels before. Although he didn't completely understand this kind of construction project, he certainly didn't have as much contact with Cao Daren.
"If this is the problem, I suggest that you use the pipe jacking method for construction." Sure enough, when Chen Xin asked about it, Cao Daren had already given a practical plan and said to Chen Xin: "I I thought that the writer had already planned to use this method for construction! Use a shield machine to tunnel, and then use a jack to push the pipe in section by section. Isn’t this a plan you had anticipated in advance?"
"The plan I envisioned is indeed to use a shield machine to dig the tunnel and then put the pipe in, but it is still a bit different from the pipe jacking method you mentioned." Chen Xin understood Cao Daren's introduction after listening to Cao Daren's introduction. What's going on with the pipe jacking method, but it does have some differences from the construction method he originally envisioned.
The pipe jacking method is actually a pipeline construction method developed with the development of science and technology in order to solve the problems of complex underground pipelines and inconvenient excavation in the city.
The main construction method is to excavate the working well to reach the working depth, and then use jacks and other tools to push a section of the prefabricated pipeline into the predetermined pipeline pipeline at the predetermined pipeline location to realize the pipeline installation. .
Of course, this technology is mainly used in the installation of large pipelines, and is divided into mechanical excavation jacking, extrusion jacking, hydraulic mechanical excavation and manual excavation jacking, etc. many different ways.
Chen Xin's way of excavating with a shield machine can also be regarded as mechanical excavation and jacking.
"In this case, we need to take heat preservation measures for the pipeline first, and then put it in the operation well for jacking operation." Chen Xin agreed with Cao Daren's plan after thinking about it, and soon Think of the problems to be paid attention to in the construction.
When Cao Da heard what Chen Xin said, he nodded and said affirmatively, "That's for sure. It's impossible to keep the pipes ready before insulation. That would be too troublesome."
Cao Daren agrees to perform jacking operations after the pipes are insulated. The main reason is that the work surface where they install the pipes is snow, not soil or rock, because if it is a harder texture such as soil or rock, the outside of the pipeline The layer-wrapped insulation material is easily worn during the jacking process.
"Can I leave the construction in this area to you? After all, I'm not a professional engineering technician, and I have other things to do." Chen Xin looked at Cao Daren and asked him.
What he said was the truth. Although he had been exposed to engineering construction when he was still at work, Chen Xin at that time was not the person in charge of construction on site, and had no experience in this area.
As for the other things he said, he was cooperating with the country. The prototype of the project that needed him to upgrade and improve has been transported to the city through the military train together with the special forces, and is now stored in the barracks.
The prototypes of related projects that were previously accumulated in the urban area are also preparing to be shipped recently, so Chen Xin really needs to deal with these things during this time, so as not to delay the progress of the country's projects.
Although Chen Xin's appearance is just a surprise to the country, the original project plan was designed without his help, but this does not mean that Chen Xin can put the backlog of work that should be completed there. in spite of.
So Chen Xin intends to clean up the backlog of work during the construction of the second heating hub and pipeline laying~IndoMTL.com~ And for Chen Xin, he came to the city for disaster relief. During this period of time, he has been busy with all kinds of things, first the ambulance station, then the railway station and the heating hub. After this time, he took a short rest on the New Year’s Day, but was also caught by Qin Lan and Mo Qing. Yan delivers a big "surprise".
This also makes Chen Xin want to take advantage of this time when everything else is on the right track, and change his mind by dealing with these backlogs of work.
—————————————————————
Chen Xin took the initiative to deal with the backlog of work, which of course was something the researchers around him could not wish for.
This researcher has been staying here since he came to Linshi. In addition to being in charge of contacting the city and the higher authorities, this researcher has also helped Chen Xin a lot, at least for In the construction of the heating hub, the researcher contributed a lot.
Previously, he needed to use the communication channels of the Linshi Municipal Government to contact the higher-level departments. Now the special forces have come, not only have built military camps, but also brought communication facilities and built a communication network. This allows this scientific researcher Personnel can use the communication equipment of this special force to get in touch with the superior department more conveniently.
This is a good thing for both the scientific researcher himself and Chen Xin. This makes the communication with the higher-level departments much smoother. After all, it was somewhat inconvenient to borrow the communication channels of the city government before. .
The special forces have no such troubles, because the reason why they are equipped with complete communication equipment when they come is that there are factors that ensure the communication between Chen Xin and the higher-level scientific research department.
