"Xiao Zhang, what will you do if the pile foundation static load test fails?"

After telling about the problem with the static load of the first pile foundation in the completed place, the Sun family asked Zhang Rui in a military test, or in a consultative tone. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"The correct approach is to continue the static load test of the second test pile, if the static load test of the three test piles are unqualified, we can only expand the scope of sampling, and at the same time cooperate with the high strain and low strain data to the design institute for design review to see if it can meet the needs of the project, if it ......"

Zhang Rui replied without thinking, as long as he has experienced several pile foundation constructions, these processes will be very clear.

Sun Jiajun nodded, "Is there any other way to do it besides the right way?" ”

Zhang Rui smiled bitterly and said: "Of course, we are a humane society, pay attention to human feelings, if I am on the scene, the first test pile has a problem, that night I will ask the inspector to go out to drink, sing, bathe, one-stop service, I believe that the inspector will be accommodating in the next test, provided that the test is not too bad." ”

"Hey!" Sun Jiajun slapped his thigh and was heartbroken.

If Zhang Rui's first answer is decent, the second answer is that the cliff is the correct way to open the construction site.

That's right, in these years, the construction unit is definitely the weakest party, if you want to do a good job, you have to increase public relations efforts, and you have to be willing to spend money!

It's a pity, it's a pity that Ge Futai didn't take the inspector into account, and the final result was: Futai was responsible for the two buildings of the project, and the static load test of the six test piles was unqualified.

It's really unqualified, and the inspector hasn't done anything with the data.

If it is only occasionally one or two pile foundations that are unqualified, and the pile foundations are not in the main load-bearing parts, Ge Futai uses the means Zhang Rui said to timely public relations, and maybe the inspector can help to change the data to fool through.

After all, the static load test technology in this year is still relatively backward, and all the data is completely manually mastered, unlike the previous life of the static load equipment and the quality supervision station directly networked, all the data is transmitted to the supervision station data center in real time, which is not fake at all.

But in the case of all unqualified, the inspector does not dare to fool even if he has the courage to do so.

Even if Ge Futai took the money to smash the inspectors, he didn't dare to modify any data.

This is no longer as simple as a common problem, but a complete quality accident, if you help the data fraud, you will have to bear the responsibility for the collapse of the building in the future!

So the matter got bigger, and the general contractor Tianyuan Group called Ge Futai to the construction site and scolded him, asking Ge Futai to solve the quality accident within half a month, otherwise he would get out of the way.

Ge Futai hurriedly summoned Sun Jiajun and others to discuss countermeasures, and was in a meeting, when the information clerk of the supervision unit knocked on the door with a supervision engineer notice and asked Ge Futai to sign.

In the case of a quality accident on the pile foundation, the construction unit is the first responsible party, and the supervision unit as the on-site quality supervision can not run the responsibility, so they have made up for a notice, and can shirk a little responsibility and count a little responsibility.

The notice and contact sheet are the most commonly used means of shirking responsibility for all parties involved in the project, and Ge Futai is also very righteous and did not let the supervising brother take the blame, but what made him collapse was that the data clerk stupidly did not realize the seriousness of the matter, and actually copied this notice to the construction unit according to the usual practice!

Now, all the participating units of the commercial residential project in the Northeast Asia Development Zone are known!

The tense is completely beyond Ge Futai's control, he can't cover it if he wants to, he can only admit it!

"Then things are even more troublesome!" Sun Jiajun sighed, "The construction unit, the supervision unit, the general contractor, and our subcontractor held a meeting overnight, and we didn't come up with a good plan for three days in a row, so we could only ask the design institute for help, hoping that the design institute could give a pile repair plan." ”

Pile repair is to depending on the unqualified pile foundation that has been constructed, within a certain range around the unqualified pile foundation, in accordance with the principle of pile filling, according to the actual situation of the site to add one or several pile foundations, so as to achieve the design requirements of the foundation bearing capacity.

As a result, when the design institute came to look at the data, his face turned black on the spot, because the data could not even meet 30% of the design requirements, how could you ask the design institute to make up for it!

Through the test data of these six unqualified pile foundations, the design institute even suspected that the remaining 80 pile foundations of the two buildings were unqualified, and the probability of sampling inspection must be expanded.

"The design institute selected 20 representative pile foundation requirements for testing, just tossed a few days ago, the data shows that 20 pile foundations, only 5 have reached the design requirements of the bearing capacity, and the other 15 are unqualified." Sun Jiajun said in a bitter voice: "Hey, now the design institute has no choice, it is recommended that the construction unit invite experts in the province to demonstrate, otherwise the design institute will never provide any remedial plan." ”

"The construction unit determined that the responsible party for this quality accident was Futai Construction Company, and all the costs caused by the remedial plan were borne by Futai, and at the same time all losses due to the delay in the opening time of the accident were investigated......"

Tragedy!

Zhang Rui stroked his forehead, not knowing how to describe his mood at the moment.

Based on his more than 10 years of work experience, once the project is carried out to the point of expert demonstration, Futai will only be more unlucky in the future.

This has nothing to do with good luck, but the key to exposing Futai's super weak comprehensive technical ability!

Futai has no experience in pile foundation construction at all!

Otherwise, such a serious mistake would not have been made at the root.

Zhang Rui began to realize that the difficulty of Futai's dungeon was a bit super high, even reaching the level of S+.

Zhang Rui sighed and asked, "What do you say...... Have you been tossing around for so long, have you found the root cause of the problem? ”

Sun Jiajun said: "I found it, and the design institute preliminarily determined that the pile head did not enter the holding rock layer, but the real reason needs to wait for expert demonstration before the result." ”

Zhang Rui smiled bitterly: "Are you just waiting?" Didn't do anything else? ”

"What if you don't wait?" Sun Jiajun frowned and said: "This kind of quality accident, everyone has encountered it for the first time, and I don't know where to start!" ”

"Drill core!" Zhang Rui sighed depressedly, feeling helpless about the lack of pile foundation tests of these guys, "Each pile is drilled and sampled, and the root cause of the problem can be determined as quickly as possible through the pile core samples taken out." ”

"Drill core?" Sun Jiajun was completely stunned, and only after a long time did he shout "oops": "Why didn't I think of it!" ”

Sun Jiajun said, quickly picked up the phone and dialed out, Shaoqing, I heard his voice say excitedly: "Mr. Ge, Mr. Ge, I have thought of a way to determine the root cause of the pile foundation quality problem, maybe we ...... Maybe we still have a glimmer of hope! ”
