Lao Hong's work efficiency is very good.

Before the expert demonstration, the core sample drilling of the third pile was completed.

Immediately afterwards, the technicians of Jianda Guji Geotechnical Reinforcement Company entered the site and began to conduct on-site analysis of the core samples.

These technicians are all students led by Shen Ye's eldest brother, and they have to compile the first draft of the cause of the quality accident from a professional point of view according to the white diagram of the pile foundation team and the on-site core sample.

The reason why it is the first draft is only to represent the position of the reinforcement company, and to conduct objective and professional data analysis of the sample.

The real finalization, and the party responsible for the accident, is the task of the experts.

In the process of core drilling and sampling of Hong Sihai's team, Party A, supervision, general contracting and pile foundation construction team all arranged personnel to witness on site.

Every time Lao Hong's workers took out the core sample, the representatives of the four families flocked to take pictures, take pictures, and record records, but they were not afraid of any party making ghosts.

"Xiaobai, when will the written documents be issued?" Shen Ye handed a bottle of Coke to a young man wearing glasses who was immersed in filling in the data.

Xiao Baihan took it with a smile, unscrewed the cola and took a sip, and immediately showed a comfortable expression on his face.

Coke, it's the first sip of the coolest, and the rest is not interesting.

Sandwiching the Coke under his armpit, Xiaobai said, "Brother Shen, don't worry, when I finish writing the draft, I can find a nearby printing shop and produce the written results." ”

Shen Ye said: "What kind of printing shop are you looking for, go directly to Party A's office to print, and make more than 20 copies in one go, saving copying." ”

When Party A's hydraulic engineer heard this, he turned his head speechlessly.

Forget it, Mr. Wang and Manager Li have specially told them that these supervisors can't afford to mess with them.

Brother Shui has been working on the construction site for more than ten years, and he has been bullied and squeezed by the supervisors before.

finally became Party A through the relationship, but I didn't expect to be bullied by the supervisor.

Said that Party A's father is very good?

Where is this going to be reasonable?

When it was almost noon, Shen Ye drove to Jianda to pick up the eldest brother.

"Have you got any preliminary results?" Brother Shen Ye asked.

Shen Ye said: "Yes, as Zhang Yi initially guessed, the three piles were caused by sediment. ”

"Even the most basic sediment problem can't be solved, and the level of this pile foundation construction unit is too average." Brother Shen Ye said.

"Big brother, have you ever encountered this kind of problem before?" Shen Ye asked.

"I have encountered that in the years when the pile foundation was first promoted, on a project in the south, a bureau of a central enterprise also used rotary digging to dry into holes, and the sediment was more than one meter thick."

"At that time, everyone crossed the river by feeling the stones and proposed a pile repair plan." Brother Shen recalled: "As a result, the design institute checked that if there are too many piles, the foundation rigidity is too strong, which is not conducive to the construction of floors of more than 100 meters. ”

"Didn't you know about high-pressure grouting reinforcement at that time?" Shen Ye asked.

Brother Shen smiled and said: "High-pressure grouting was also implemented a few years ago, at that time we demonstrated several times, and finally adopted a more conservative method, appropriately added a few piles, and increased the area of the bearing platform and raft. ”

Shen Ye asked again: "This building, if high-pressure grouting is used, there should be no problem, right?" ”

Brother Shen said: "Why, I'm scared, why didn't you think about the consequences when you and Xiao Zhangkeng were at the beginning?" ”

Shen Ye said embarrassedly: "This is my company, and it is false to say that I am not afraid." ”

"Rest assured, the high-pressure grouting reinforcement technology is very mature, not to mention that the pile foundation static load test will be carried out after reinforcement, and generally speaking, there will be no problems."

Brother Shen said: "Besides, once there is a problem, Party A and experts will take care of it, and the responsibility of the supervision unit is very small." ”

Is it small?

Shen Ye didn't know.

Seeing that the fourth child was still a little confused, Brother Shen said, "Say you're stupid, you're really stupid!" Think about it, what did Xiao Zhang make a big deal about from the beginning and stab him on the floor of the quality supervision station? ”

Isn't it for the sake of pit Party A and get out of the way?

Shen Ye stubbornly pinched the sentence that was about to blurt out.

Yes, Lao Zhang did this in full accordance with the construction process.

When it is found that the hidden danger of the accident is serious, and the construction unit refuses to rectify or does not stop the construction, the supervision unit shall report to the relevant competent department at the higher level in a timely manner.

Zhang Yi walked out of this process, indicating that the supervision unit has fulfilled its duties.

There are very few supervision units in the country that can do this step.

To be honest, Brother Shen was also a little curious about Zhang Yi.

"Is Xiao Zhang going to the construction site today?"

Shen Ye said: "It must be there, when I came to pick you up, he was re-improving the reinforcement plan." ”

"Huh? That's a good plan, but what needs to be improved. ”

Shen Ye said: "As soon as he heard that he was going to make a paper, he felt that the thing was too thin, so he grabbed Xiaobai and studied it for a long time, and it is estimated that by the time we arrive, it will be almost done." ”

Brother Shen nodded again and again when he heard this, and said, "You learn from Xiao Zhang, look at others, and then look at you." ”

Shen Ye hurriedly closed his mouth, if he refuted at this time, he would definitely usher in a harsher reprimand.

The brothers had a light meal outside, and it was half past one in the afternoon when they arrived at Party A's office.

There was still half an hour before the expert argument, and several experts arrived early.

As soon as they saw Brother Shen come in, several experts immediately got up to greet him.

There is no way, Brother Shen is too famous in the industry, and some of the current norms and standard atlas compilers have his name.

In the face of the warm welcome of Mr. Wang and others of Party A, Brother Shen just nodded politely, shook hands, declined the Huazi handed by the other party, and then looked around the audience, looking for Zhang Yi's figure.

Shen Ye naturally knew what his eldest brother was looking for, and beckoned to Zhang Yi, who was sitting on the second row of chairs in the conference room.

"Lao Zhang, come and sit here."

"Brother Shen is good." Zhang Yi took the reinforcement plan of the hot call, and walked over to greet Brother Shen with a smile.

Brother Shen looked at him with a smile.

To be honest, in addition to being tall, looking more handsome, younger, and sunny than Shen Ye, I don't seem to see any other advantages.

"You're Xiao Zhang, not bad, the fourth brother has been talking about you a lot lately."

Zhang Yi grinned awkwardly and glanced at Shen Ye.

Lao Tzu is a gentleman, not a base.

What do you mean by talking about me?

"Don't be restrained, we don't have outsiders." Shen Ye became darker and darker the more he described.

Zhang Yi didn't bother to pay attention to him, and said, "This is a newly perfected reinforcement plan. ”

"Okay, I'll have to take a good look." Brother Shen took the plan, took out his reading glasses from his bag, and began to check the plan.

Seeing that the experts had arrived, Mr. Wang coughed lightly twice and began to announce the beginning of the expert argument.

Zhang Yi opened the recorder in his pocket and placed it in the center of the conference table.

Mr. Wang said: "What's that, the hard work supervision unit will help sort out the argumentation minutes." ”

For this expert demonstration, Party A's project department is very well prepared.

A part of the on-site data and photos were collected, and a special PPT report was made.

In this way, it is better for experts to understand the situation quickly than simply talking about it.

In fact, when receiving the experts at noon, Mr. Wang had already given a general overview of the situation.

It's just that after these experts knew that Brother Shen was coming, they invariably reached the mentality of touching fish and making soy sauce.

Everyone looked at the projector, only Brother Shen was unmoved, still staring at the reinforcement plan in his hand, and muttering a few words to Zhang Yi from time to time.

Shen Ye had to be distracted and listen to what the two of them muttered.

I heard Brother Shen ask: "If 54 piles are reinforced, it seems that you can't make a lot of money." ”

"It doesn't matter, I'll tear down a few more when the time comes, let them rework, and if they don't rework, they can increase the pile diameter."

Brother Shen asked, "How much is the reinforcement budget?" ”

"Talent and machine profit regulation tax, how can you start with 2 million."

Zhang Yi added: "Brother, you have face and qualifications, and I have people and materials and machinery, how about we split the account fifty-fifty?" ”

Brother Shen nodded, acquiesced in the proportion of spoils, and said, "That's ...... There is something to be added to this plan. ”

Zhang Yi is also a bachelor, and said directly: "Okay, you can change whatever you say, I will listen to you." ”

After Shen Ye listened, his whole person was not good.

No, is this still the upright big brother I am familiar with?

How can there be such a thing, Party A is still talking on it.

The two of you are discussing how to increase the cost and how to divide the spoils......

Fortunately, the surrounding area is full of their own people, and if outsiders hear it, it will have a bad impact.

Hey, you guys should pay attention to the image.

Five minutes later, Mr. Wang finished talking about the on-site situation, and also put forward the specific requirements of the developer, and then invited the experts to speak.

The experts didn't say a word, and looked at Brother Shen in unison.

Brother Shen took off his glasses and said, "Let's go directly to the scene to have a look." ”

So, everyone came to the scene around Brother Shen and watched the samples drilled out repeatedly.

An expert squatted down and said: "The quality of the pile is OK, there is almost no sediment, muck or other debris in the pile, the pile body is central, there is no eccentricity, and there is no place to break the pile, how can you not bear the static load test." ”

If the eccentricity of the pile is too large, it will cause the pile to be prone to bending and shear deformation under the load, resulting in unqualified static load test.

This looks like you've done your homework in advance.

"Is it possible that the survey report is inaccurate, resulting in errors in various parameters during the design."

Someone put forward another idea, "I heard that last year's Baiboshan project, because of the sloppy survey of the floating skin, and finally the design institute readjusted the pile foundation construction parameters. ”

Yo, this one knows a lot about the dynamics of the industry.

The survey unit also came today, and hurriedly jumped out and explained: "We are all surveys done in accordance with the rules, and the photos of the process are well preserved, ready for reference at any time!" ”

Well, the incident in Baiboshan has had a great impact on the entire survey industry, and the survey units have converged a little bit when they come in.

Experts gossip that the pile foundation static load test is unqualified for several reasons.

It is possible that the survey unit has problems, and the geological data provided is not accurate.

This point has basically been lifted with the explanation of the survey unit.

It may also be a problem with the design unit, such as the coating thickness, friction angle, internal friction angle and other parameters are not well considered......

Brother Shen saw that these guys were still grinding, shook his head, and said finally: "This construction unit is too watery, and the sediment at the bottom of the pile is 50 cm, so you can imagine the thickness before pouring." (End of chapter)
