The rock formation, the so-called holding layer, is like if you are wading across a river, and your feet have to step on the bottom of the river, not on the surface of the water. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The purpose of entering the rock is to ensure that the weight of the whole house extends from the pile foundation to the rock formation, and a pile that does not enter the rock can basically be said to have no effect.

Therefore, it is very important whether to enter the rock or not, and whether the depth of the rock enters the rock meets the requirements of the specification!

Generally, the experienced construction unit will clean the pile hole in time after the pile length reaches the design length, and finally determine whether to enter the rock according to the rock core sample taken out by the drilling rig and the survey report provided by the local geological exploration and design institute.

And Futai construction company before the construction of some ordinary residential commercial housing, this is the first time since the establishment of the company to carry out pile foundation construction, even the "rotary drilling into the hole pile foundation construction plan" are borrowed from other large engineering projects to modify, with its technical strength to gnaw down 200,000 square meters of large projects, the hardships can be imagined.

Sun Jiajun knew that his ability was limited, so after the start of construction, he frantically made up for the relevant construction technology, and learned while exploring the construction, in order not to let the general contracting company and the developers look down on him, Lao Sun took great pains to stumble and finally completed the construction of the pile foundation of a building, and was about to breathe a sigh of relief, but the result was a big mess.

At this moment, Sun Jiajun's heart is broken and remorseful!

If Zhang Rui had come to Longjing for an interview two months earlier, if he had been on the construction site at the time of construction, with his rich experience in pile foundations, there would never have been such a big quality accident!

However, there is no regret medicine sold in the world, otherwise even if the family is bankrupt, Sun Jiajun will buy it and eat it, and go back to the past to prevent this major quality accident.

"I didn't see it, Xiao Zhang, you actually have construction experience, it's rare, it's so rare!" Liu Suqiu patted her little hand with surprise on her face.

Sun Jiajun also sighed and said: "Well, it's really rare, you can see that you have learned real things in your hometown, and you can find a good employer based on this alone." ”

Wait, this style of painting is wrong!

I don't want to enter your company to get money to buy a diploma, is it really good for you to refuse people thousands of miles away?

Zhang Rui was a little confused, how long has it been since you have recharged your EQ?

Liu Suqiu glanced at Zhang Rui, thought for a moment, then smiled and said tentatively: "What's the matter, I listen to you...... It seems that I don't plan to do it in Tailin, and I kind of think of the plan of an internship in Futai? ”

Zhang Rui hated to give Liu Suqiu thirty-two likes, Sister Qiu, you are so good, Sister Qiu, the style of painting has finally developed according to the planned direction.

Zhang Rui hurriedly made a very embarrassed expression and said: "Just now I communicated with a few students who were going to Tailin for an interview, and found that the personnel over there seemed to be a little saturated, the personnel of the first and second project departments were fixed, and although the third project department needed to form a team, it was impossible to use all interns, so I didn't want to compete with my classmates for internship places......

What he said was seven points true and three points false, coupled with Zhang Rui's acting skills, he was stunned to bluff old rivers and lakes like Liu Suqiu and Sun Jiajun.

Liu Suqiu sighed with emotion, sighing that the years are like knives, they also used to value friendship and classmate friendship more than Jinzhen, but this innocence could not be maintained for long, after the baptism of the social dyeing vat, everyone's thoughts began to turn to money and interests, and the friendship between classmates was weakened.

Don't look at the guys here today talking and laughing, in fact, it all depends on Liu Suqiu to reconcile it, her classmates helped her back then, and she also tried her best to help her classmates, trying to maintain those feelings that were gradually forgotten.

Liu Suqiu is a very emotional person, since he found a rare flash in Zhang Rui's mood, he subconsciously began to help match.

"Old Sun, did you hear it, Xiao Zhang wants to enter Futai."

Sun Jiajun pursed his lips, his brows were tightly locked, with a complex expression that was both heartfelt and embarrassed, and he pondered for a long time before he said: "It's no problem to come to Futai, it's a matter of one sentence, but ...... But now Futai's situation is a bit special, and I'm worried about making a small pit. ”

"You're afraid that Xiao Zhang Bai won't get paid for his work, right?" Liu Suqiu said with a smile.

Sun Jiajun looked embarrassed as if you were knowingly asking, nodded and said, "Yes, he has such a good foundation, and he is too ...... to come to Futai."

Liu Suqiu hummed and said: "You also have good intentions, but at the moment, the only construction companies we know are you Futai and Tailin, and several other construction companies are either unpopular or unreliable, and Xiao Zhang doesn't want to compete with his classmates, so ...... You know what I mean, right? ”

"I understand, but the salary ......" Sun Jiajun still has a bitter face.

Liu Suqiu sneered, pointed at him and said, "Old Sun, old Sun, let me say what is good about you, since I have talked about this, does Ge Futai dare to repay the debt?" ”

Zhang Rui was overjoyed when he heard this, Sister Qiu came out, and things were done.

Sure enough, after having Liu Suqiu's assurance, Sun Jiajun was not entangled, patted his thigh and said: "Okay, if I don't agree again, I won't give you face to Sister Qiu, I will take this matter, and I will tell Mr. Ge tomorrow, it just so happens that Xiao Zhang has such a good foundation, and he can also show his skills in our project." ”

"Ouch, you're a tough guy!" Liu Suqiu scolded with a smile.

"Thank you, Sister Qiu, thank you, Mr. Sun." Zhang Rui hurriedly thanked him.

Being able to help Zhang Rui, Liu Suqiu was in a very good mood, "Come, let's have a drink, I wish Xiao Zhang a smooth work, and congratulations to Lao Sun for his wings." ”

The three of them clinked glasses, Liu Suqiu drank the beer in the cup, Sun Jiajun drank half of the liquor, and Zhang Rui poured it directly into it.

"Tsk, this momentum of drinking will also be a fierce general in the drinking field in the future!" Liu Suqiu smiled: "Old Sun, you should also be happy, don't ink." ”

Zhang Rui smirked.

"Oh, I'm going to die!" Sun Jiajun gritted his teeth and poured the wine in the cup, and hurriedly pressed the vegetables.

After the interview was negotiated, Zhang Rui could feel that Sun Jiajun was a little closer to him, at least he was not rejecting people thousands of miles away like just now.

So the two sat together and began to exchange construction experience, at this time Zhang Rui became extremely cautious, some things were said cleanly, and some things were deliberately wrong, so as to save some face for other people's grandchildren, right?

If you behave too well, how will your grandson be an old driver in the future, so stay a line and see each other in the future.

Zhang Rui deliberately made a mistake, Sun Jiajun also found the pleasure of being an old driver, after a while, Sun Jiajun's opinion of Zhang Rui is getting better and better, and he feels that this young man has a very good personality, willing to learn and learn, it seems that he really suffered on the construction site, and went through a lot of detours to temper today's temperament.

In short, Sun Jiajun was very satisfied.

Sun Jiajun was satisfied, but some people were greatly dissatisfied.

Since Zhang Rui sat down on Liu Suqiu and Sun Jiajun's side, Zhu Xijie has been paying attention to it, seeing that they are talking and talking happily, the bad feeling in Lao Zhu's heart has risen.

After the three of them clinked glasses and drank all the wine in the glass, Lao Zhu felt even better.

Damn, Hu Tingting's big beauty was cut off, even if the seedlings that Lao Tzu fancied were also robbed, unhappy, Lao Tzu was very unhappy!

Zhu Xijie stood up suddenly, and strode over to disrupt the situation.
