At the same time, pour the underground structure of each layer until the bottom plate is sealed.
People who don’t know engineering can’t imagine how much extra manpower and material resources we need.
What shocked us most is that during the construction, the reinforcement works of the bottom plate are very large, but there are only 11 excavation openings, and tower cranes can not be used in all places.
Then, instead of directly digging out the soil, the beam slab floor structure of the zero meter floor shall be constructed as the horizontal support.
Of course, we didn’t “show mercy” and asked the person in charge of the project directly, “why is the construction so slow? Explain it!” After some understanding, we know that the main reason for the original slow construction is that the reverse method, which is very different from other buildings, is adopted.
The layman watches the excitement while the expert watches the doorway.
There are only 11 excavations in the whole residential plot.
It took a long time to contact the person in charge of Zhengrong zique engineering department.
Therefore, a large number of steel bars need to be manually transported from the outlet to the site for installation.
The person in charge of the Engineering Department said: “always cooperate with the subway department to monitor.
It includes the best expert groups in Shanghai and Tianjin, and sets up management personnel with international first-class qualifications to pass the scheme over and over again.
Why use the reverse method? This is about the geographical location of Zhengrong zique.
The head of the engineering department made a vivid analogy: “there are many small ants working underground”.
It is just located at the intersection of metro lines 2 and 6 and belongs to the upper cover of the metro.
Each layer requires additional labor to complete piles of soil, and then gradually transport it from the excavation mouth to the ground.
The construction difficulty is unimaginable, and the progress is really not fast..
As a luxury house with a house price of about 60000, it has always been very low-key and rarely hyped.
The converse approach may be summed up in twoorthree sentences, but the real implementation is a huge project.
What’s the concept? It’s equivalent to “digging with an ear scoop”.
In other projects, three piles are driven in one day, and Zhengrong zique can drive one pile in three days.
Cameras should be installed on the mechanical arm, because we do not know what the following conditions are.
At the request of the majority of fans, we decided to conduct an on-site investigation to see how far it has been built.
Finally, it was decided to take the most difficult road and adopt the reverse construction method.
After the underground foundation frame is built, the cover plate shall be sealed, and then the above ground part shall be built.
The head of Zhengrong zique Engineering Department said that the deviation error of some data around the underground track of line 2 and line 6 should not exceed 2mm, otherwise it will affect the safe operation.
In order to work out a solution, Zhengrong zique successively invited major experts for “consultation”.
As the construction is from top to bottom, the upper part has been covered, but the lower part needs to be excavated and poured.
You can imagine how difficult the “upside down” construction is.
Therefore, when we go to the real estate construction site, we can’t see the underground structure, but only the buildings above the ground.
So that the surrounding environment will not cause pavement subsidence, foundation subsidence and other problems due to excessive deformation value.
“The consequences are unimaginable and will affect the travel safety of citizens.
Ringlock Scaffolding System Ledger End
For example, the first tianyuehai River and Yingshun house are all because they have to cooperate with the subway, and the construction cycle is super slow.
Once there is an error of a few tenths of a millimeter, we will immediately start the emergency plan and study the solution…” speaking of this, we finally understand that the construction of Zhengrong zique is slow and is stuck.
It fundamentally ensures the safety of subway operation.
“There’s no doubt about what’s going on outside,” said the fans Yes, I really can’t answer this question.
It can be seen at the scene that the subway outlet is next to the office block of Zhengrong zique.
If the normal construction method is followed, as long as the soil position and structure change during the foundation laying process, it is likely that the error will exceed 2mm, which cannot be guaranteed to be 100% controllable.
From the online signature data, it is almost liquidated, and the silent ones are selling very fast.
As we all know, whenever we “encounter” the subway, there is no trouble in underground construction.
First, the supporting structure is built along the underground frame.
Zhengrong zique is really a little “strange”.
Therefore, the operating conditions are very poor.
The key point of the reverse construction method is the verticality of the column, which requires extremely high deviation accuracy.
Other construction sites “are full of excavated openings” because they are dug from bottom to top; Zhengrong zique is excavated from top to bottom.
As we all know, it will open in September, 2019, which is more than two years.
Build the house from the bottom to the top.
Recently, fans often leave messages, all paying attention to the same real estate – Zhengrong zique.
To put it bluntly, first fix the position of the underground soil, so as to ensure that the error of the subway does not exceed 2mm.
There are cases everywhere.
The person in charge of Zhengrong zique Engineering Department introduced some details.
Then dig from top to bottom layer by layer, instead of the traditional excavation from bottom to top.
As the name suggests, the reverse method is “reverse”, which is difficult and takes a long time.
The accuracy of subway outlets for underground tunnels is appalling, calculated in millimeters.
The actual picture of the construction site of Zhengrong zique is more than that.
Give you a simple popular science, what is reverse practice.
Not quite the same as the rumor, the site is under construction.
This requires high construction technology.
Equivalent to a solid frame buried in the soil.
Real map of Zhengrong zique construction site real map of Zhengrong zique construction site in this way, as the structure itself acts as an internal support, the strength is very large, and the compression deformation value is almost equal to zero.
The first step of the reverse method is “groove wall reinforcement”.
Last Saturday (December 4), we came to the construction site with questions.
But the core problem of Zhengrong zique is that the underground structure is too close to the two subways.
The ground and underground of Zhengrong zique are in the process of construction.
No matter which department you stand in, ensuring the safety of people’s livelihood must be put in the first place,” said the person in charge of the engineering department.
