Liu Suqiu's words successfully attracted everyone's attention, and everyone looked at this side with complicated eyes. Pen, fun, pavilion www. biquge。 info

Fu Group's mood is anxious, Liu Suqiu, you can, since you have a treatment plan, why didn't you say it earlier, you have been watching everyone lively just now, right?

Wang Dapeng and Su Zhipeng, two experts, were engrossed, and their eyes bloomed with a strong desire for knowledge, and they wanted to know what kind of method the other party wanted to use, which could not only ensure the quality of the project, but also not delay the construction period.

After all, in this particular environment, quality and duration are completely contradictory.

What can you do about things that even geologists can't solve?

Xu Jun simply narrowed his eyes, his whole person tightened into a bow, he magnified his hearing to the extreme, and his brain spun wildly at the same time, ready to interrupt the other party's ridiculous plan at any time.

Because in Xu Jun's cognition, there is no method that is effective for this project.

"Xiao Zhang, come on!" Liu Suqiu finished speaking lightly, picked up the teacup and took a sip of tea.

Zhang Rui said calmly: "Our current problem is that the pile foundation inspection cannot meet the design required strength. ”

Everyone nodded, you're not talking nonsense, if the pile foundation is qualified, we won't have to hurt here.

"So as long as we find a way to make the pile foundation test qualified, does it mean that the problem is solved?"

Another nonsense!

Xu Jun snorted coldly, "Are you planning to use a crane to pull out each pile and re-drill and pour?" ”

"Huh! That's a good idea! Wang Dapeng said loudly: "From a theoretical point of view, it is feasible. ”

"The theory is like this, but don't look at these pile foundations to fail the inspection, if you want to pull them out of the ground, you need to use a truck crane of more than 35T, 80 piles to pull out for a long time, at least two months!" Xu Jun said with a snort.

"Yes, this method is good, but it also needs to take a certain amount of risk, in case the re-poured pile foundation is not qualified again......"

Su Zhipeng didn't say anything further, because Fu Groupming interrupted with a wave of his hand, "No, the construction period does not allow." ”

Xu Jun sneered and raised his eyebrows at Zhang Rui proudly.

Boy, dumbfounded, I thought about this method before, because I knew that the name of the Fu group would definitely not pass, so I didn't bring it up.

You're still too tender!

Zhang Rui smiled and said: "Pulling out the pile and redoing it is not a theoretical inference, there are such examples in reality. But I'm going to say that the solution is safer and faster than this. ”

Without giving Xu Jun a chance to interject, Zhang Rui said directly: "Everyone has been to the scene just now, I don't know if you have noticed that there are two holes in each engineering pile." ”

Everyone nodded, and the chief engineer of the design institute said, "Aren't those two holes used by you for core sampling?" ”

"That's right, I have written very clearly in the analysis and comparison report, these two holes run through the pile foundation and reach the bottom of the pile." Zhang Rui said, unhurriedly turned out the "Design Plan for High-pressure Grouting Treatment of Sediment at the Bottom of Bored Pile Piles", "Please trouble the developer to make dozens of copies of this plan to ensure that everyone on site has one copy." ”

The developer's data clerk quickly ran over and picked up the plan and went out to copy it.

"My treatment plan is to use the two pile holes to fully wash out the sediment, mud, soil and other debris at the bottom of the pile through a high-pressure water gun, and then pour two grades of concrete higher than the strength of the pile foundation."

After Zhang Rui's plan was finished, the audience was silent.

This is an unheard of solution!

After a short silence at the scene, the chief engineer of the design institute first asked, "Can you tell us about the specific principle?" ”

"The principle is very simple, through high-pressure grouting, the gaps at the bottom of the pile, karst caves and various hidden dangers are fully strengthened." Zhang Rui explained with a smile.

The chief engineer of the design institute suddenly realized, patted his head and said: "That is to say, strengthen the pile bottom, so that it reaches or even exceeds the strength of the bearing layer, so that the rock below and the pile foundation become a whole, right?" ”

"That's right! It's okay to understand it this way! Zhang Rui nodded again and again, after all, it came out of the design institute, and his brain turned fast!

Xu Jun frowned and pondered for a moment, shook his head and objected: "How can you determine how big the gap and karst cave area are below, what if there is a 100-cubic karst cave below, in case there is an underground river below, it is useless for you to pour high-grade mortar like this!" It's a bottomless pit! ”

After Xu Jun finished speaking, he turned his head and said to the name of the group: "Mr. Fu, I think this plan is inappropriate, because there are no successful cases, and there are considerable hidden dangers!" ”

"Is there no hidden danger in the pile repair plan?" The corners of Zhang Rui's mouth curled and said: "Xu Gong, although the pile repair plan is mature and has cases, the cost required is quite huge, whether it is the survey, design or construction unit, it needs to carry out considerable manpower and material investment!" ”

"That's right!" The chief engineer of the design institute echoed and said: "If the pile is repaired, all the building patterns on the ground need to be adjusted, and there is a considerable problem, too little pile can not meet the strength, too many piles can easily lead to too strong foundation rigidity, and the safety hazards of high-rise buildings with too rigid foundation are greater!" ”

"Ah, there are still hidden dangers?" Fu Groupname asked in surprise.

"Of course!" The chief engineer of the design institute said: "More importantly, the 80 piles we built before have become waste piles, and Zhang Gong's method can not only save costs, but also save the construction period to a large extent, although there is no successful case, but I think you can give it a try!" ”

Fu Group Name was moved, as for Xu Jun's suggestion, he had already ignored it!

The problem is all made by your investigation institute, if you don't take the initiative to find a way, forget it, he is singing crookedly here!

So, let's argue for this high-pressure ...... What to do with it. Fu Group Name hurriedly moved on to the next link.

At the beginning of this side, the developer's information clerk rushed in with more than 20 copies of the plan, and one was distributed to each seat.

Everyone quieted down and carefully looked at the "Design Plan for High-pressure Grouting Treatment of Sediment at the Bottom of Bored Pile Piles" page by page.

Before the plan was finished, Mr. Sun of the design institute suddenly pushed the door in, and said in an excited voice: "Mr. Fu, my colleagues in the south gave me a treatment plan, and they tried it and succeeded." ”

"Oh?" Fu Group's mood was much better, "Zhang Gong also proposed a good plan just now, we are arguing, you can talk about your plan first." ”

"Pile borehole high-pressure grouting, and at the same time add early strengthening agent, dehydrator, expansion agent, ......" Mr. Sun didn't finish speaking, Fu Group's name slapped the table, laughed and said: "Haha, Lao Sun, you are a step late, our Zhang Gong has already come up with the plan!" ”
