Chapter Eighty-Three: Pouring Together or Separately?
and Wei Jian ran Shangyunzhuang Station, Weijiazhuang Station and Haocun Station, and it took a whole day, and then there was nothing to do with Wei Jian, and everything accumulated on Shucheng's head. £∝ Top Novel,
Back at the station, Shucheng had to edit out the unloading plans of the three stations, and draw the general problems on the CAD with the schematic diagram of the stacking of switches and rails, and finally paste it into the plan, with graphic descriptions.
These processes are not complicated for Shu Cheng, they just take a little more time.
If it was Shu Cheng in the previous life, he would definitely be dizzy by these things, after all, in the face of unfamiliar things, people will inevitably have a process of adaptation.
Before he was halfway through tidying up, Han Zhao knocked on the door and walked in.
These days, Shucheng is busy ignoring Han Zhao, but fortunately, the renovation and construction of the signal building is here, although there are many places that need to be inspected, but due to the poor management model of Jersey, many inspection procedures have been omitted.
This is also the guide, Wan Yong, this guy is not much of a bird Han Zhao.
"Minister Shu, why are you working so hard." Han Zhao showed a mouthful of yellow teeth and smiled.
"Han Gong, I'm desperate, some things need to be sorted out first, otherwise it will be troublesome to take them out when the leader wants them." Shu Cheng stopped what he was doing and moved a chair for Han Zhao to sit on.
Shu Cheng knows very well that the project supervisor usually does not look for the person in charge of the project department or the technical personnel, if he has already come to find it, it means that there is either a problem with the construction site, or he wants to make some benefits.
"Han Gong, Wan Yong still needs you to worry about it, I don't know much about housing construction." Shucheng Road.
"It's okay, with me, I'm about to pour the daughter wall, there must be a gap for every two meters, and the template of the daughter wall is also upright, Minister Shu will go and talk to Wan Yong tomorrow." Han Zhao said.
As soon as Shu Cheng heard it, he knew what was going on, before pouring, he had to report to the supervisor for inspection, which was a necessary process.
For these, Shu Cheng fully understands that the signal building will be completed in a month, and if Han Zhao doesn't get some benefits from Wan Yong, he won't have a chance in the future.
"Han Gong, don't worry, I look for Han Zhao every day, by the way, Han Gong, in the future, you still need to take good care of the leveling and roadbed, as for other things, I will arrange it for you." Shu Cheng gave Han Zhao a look that everyone understood.
"No problem, as long as it doesn't affect the quality, it's easy to say." Han Zhao showed a mouthful of big yellow teeth and smiled.
Obviously, he and Shu Cheng both knew what they meant in each other's eyes, and their purpose of coming to Shu Cheng this time was achieved.
Watching Shu Cheng leave the room, Shu Cheng sighed and thought to himself: The supervisor of the Jersey Line is really good.
In the Xiantong line, the supervisor is embarrassed to take the benefits, compared to the Xiantong line, the supervisor of Jersey is no different from his own people.
In the next two days, after three days of pumping water from six pumps, the overall water level around the foundation pit finally dropped.
The excavator and the loader worked continuously, and finally at six o'clock in the morning of the third day, the foundation pit was almost dug up, and after the trimming slope and foundation treatment on the morning of the third day, the excavation work of the foundation pit came to an end.
Subsequently, under the leadership of the technicians of the construction team, the anchor beam at the bottom of the foundation pit was dug out, and a layer of gravel was filled at the bottom of the foundation pit, and the workers began to tie the bottom plate steel bar of the sliding bed board.
At this time, another question arises, is it to take the sliding bed board and the distribution beam, is it poured together?
Because the sliding bed board and the distribution beam are finally connected together, and poured at the same time, in the process of jacking, the supporting force will be greatly improved due to the close connection of the sliding bed board and the distribution beam.
If it is not poured together, then between the sliding bed slab and the distribution beam, there must be a sequence, so that at the junction of the sliding bed slab and the distribution beam, there is a connection between the old and new concrete, and this place, in the process of jacking, is very easy to split, once the division is too large, the sliding bed slab is very likely to follow the frame culvert, and be jacked away.
In this case, the frame culvert is absolutely not able to go in, and it will become an accident!
Theoretically speaking, it is best to pour the sliding bed board with the distribution beam to prevent accidents, but when Shucheng found Lao Yan, the technical leader of the construction team, and told him his idea, Lao Yan did not agree.
"Minister Shu, it's not that I don't follow your method to do it, the problem is that once the sliding bed board and the distribution beam are poured together, the template in the vertical direction of the distribution beam is not good to stand upright, if this template is not upright, it is not parallel to the frame culvert at that time, which may affect the jacking construction." Lao Yan expressed his thoughts.
Lao Yan's meaning is very simple, if two parallel walls, you can put a top pickaxe in the middle, if one wall is vertical, the other wall is oblique, then even if you put a top pickaxe, you can't really put the top pickaxe.
"Is it difficult to keep the formwork that distributes the beams vertical?" Shucheng Road.
In the previous life, Shucheng did a lot of frame culvert jacking, basically all of which were poured at the same time as the sliding bed board and the distribution beam, of course, there were also separate pouring.
"It's very difficult, and if you don't keep it vertical, it's a problem to have an impact on jacking." The old face is embarrassed.
"What if the old and new concrete crack during the jacking process if they are not poured together?" Shu Cheng frowned.
"Minister Shu, didn't you add 5.5 meters long to each meter, with two ends with trenches and 22mm in diameter? There is absolutely no problem, and the sliding bed plate is poured first, and the distribution beam and the frame culvert bottom plate can be poured at the same time, which can completely save the construction period. Lao Yan said.
Indeed, when designing the sliding bed board and the distribution beam, at the place where the sliding bed board and the distribution beam are connected, Shucheng specially added such an item, which is also for the sake of safety.
In fact, Shucheng sets up a 22mm steel bar every other meter, which is already quite conservative, and in Lao Yan's opinion, it doesn't matter if it's two meters.
What's more, as Lao Yan said, pouring separately can completely save the construction period, otherwise, the pouring of the sliding bed slab will wait until the construction of the distribution beam reinforcement and formwork is completed, and then pour, which takes more time, not to mention that today it began to work in the rear of the distribution beam position.
"Okay, then let's do it first, by the way, after pouring the sliding bed board, how to put the prefabricated line of the frame culvert for you, I'll put a few points for you." Shu Cheng thought about it and felt that there was no problem, so he changed the topic.
"You directly release the four corners of the frame culvert for me, and there are two middle lines, and you don't have to worry about the rest." Lao Yan replied.
"Nonsense, I have to take care of it if I put so many points, I thought you only needed me to put two points." Shu Cheng rolled his eyes directly.
Engineering units, some large-scale projects, have special personnel to release the line, set up a survey team, but the 31st Railway Bureau has some exceptions.
The personnel of the Engineering and Technology Department of the 31st Railway Bureau not only have to manage the on-site technology, but also to pay off the line and manage the site, which is almost a universal talent!
Shu Cheng was born with measurement and is extremely proficient in measurement.
Generally, the pay-off of the project department is to release the coordinates of the points that need to be put out according to the two controls, usually using the rear rendezvous method. Sometimes, depending on the visibility situation, a known point will also be used to release the line.
However, the release of the Jersey project department is completely different, because the railway has been established for too long, and there are residences around many control points, which cannot be seen at all, and each unit project tends to be scattered, so it is impossible to use control points to release the line.
Even if the station turnout is put out, Shucheng also uses the original immovable turnout to put the turnout that needs to be moved on the other side.
The culvert pay-off is even simpler, such as the flat change and vertical pay-off of Shangyunzhuang. Shucheng set the midpoint of the culvert on the railroad tracks, which, to put it bluntly, is the central mileage of the culvert.
Then set this point to the (0,0) point in the coordinate system, and the point to be noted here is that the construction coordinate system and our mathematical coordinate system are reversed, that is, the mathematical x-axis is the y-axis, and the y-axis is the x-axis.
Measure 20 meters from this point in the direction of the line, set its coordinates as (20,0), and in this way, the coordinate system is built, which is what we call the x-axis.
Then according to whether the frame culvert is on the left or right side of this coordinate, for example, the closest distance between the frame culvert and the right side of the x-axis of this set coordinate is 20 meters, then the coordinates of the frame culvert near the center of the line side are (0, 20), and the positive and negative signs are the same as mathematically, the y value on the left side of the x-axis is negative, and the x-value below the y-axis is negative.
Far away from the line side, the coordinates of the center of the frame culvert are (0,45.8), which is actually quite simple to calculate for the coordinates of the straight line segment.
When waiting for the line to be released, directly put the two points on the railroad track that the total station looks back on, and put out the points that need to be put out of the frame culvert.
ps: That, this book is not a stallion Wenha, and there are fewer emotional dramas, except for railways or railways, there will be less professional aspects in the later stage, so let's take it as a construction guide in the early stage. I thought about it, I don't plan to let Shu Cheng contact Wu Qingling so early, let's write out the real blind date process and let someone miss it.
