Getting up, dressing, and putting on hard hats, Li Huayong and his cousin walked out of the shed.

Like all workers, Li Huayong now lives in the shed, but as the foreman who leads the shift, he has a little privilege, Uncle Gen and Zhu They separated him from a single room, equipped with a pair of tables and chairs, so that Li Huayong can write and paint in it, which also gives him a little private space.

Pengcheng in July is extremely hot, and living in a shed is a very uncomfortable thing. Not to mention air conditioning these days, even fans are very few. Fortunately, it rained lightly this morning, and the weather is not so hot now--- which is why Li Huayong was angry at the pillar just now, and finally got a good night's sleep, it was still a very short time, so it was stirred up.

After walking out of the shed, Li Huayong saw at a glance the place where the project department and Party A's personnel were located.

At present, it is the climax of construction, the drilling rig is roaring, the voice is boiling, and there are a lot of people on the whole construction site. Moreover, this project covers a large area, with a total construction area of more than 60,000 square meters, and the entire factory covers an area of more than 300,000 square meters. Li Huayong's current position is about 300 meters away from that place in a straight line, but he still found his target at once.

Because in that place, there was an extremely brightly colored sun umbrella.

"Dunzi, why do you say those Xiangjiang people are so delicate? ”

Li Huayong smiled:

"Pillar, you have wronged them, the umbrella is not because the person is delicate, but the instrument under the umbrella is delicate. ”

Of course, the people who are qualified to play sun umbrellas on construction sites are not because of people, but because of instruments, measuring instruments.

Theodolite, level, rangefinder, total station, GPS receiver... These things commonly used on construction sites should belong to precision instruments, which have a characteristic, that is, they are very sensitive to temperature, and when the external temperature difference is too large, it is easy to affect the accuracy and accuracy of measurement. Because in order to ensure the quality of surveying and mapping, it is necessary to "open an umbrella operation".

Especially in this era, "umbrella operation" is written into the "engineering survey specification". It's just that in later generations, as the instruments became more and more advanced, the instruments were no longer so sensitive to temperature. Although this rule has not been abolished, the "umbrella operation" is becoming more and more difficult to see.

Seeing the brightly colored sun umbrella, Li Huayong roughly knew what was going on. In that place, just yesterday, the surveyors of the project department carried out the positioning of dozens of pile foundations, which is also the last batch of more than 800 piles.

Since the pillar said that there are Xiangjiang people on the site, it should be Party A organizing personnel to check and retest the positioning of that batch of piles, which is a normal procedure and a very necessary procedure. Thinking of this, Li Huayong walked towards that place with the pillar.

Under the sun umbrella, a Xiangjiang engineer is operating the instrument, and Lin Wei, as the "director", is meticulously recording something.

Lin Wei suddenly noticed something unusual, and when she raised her head, she quickly saw a pair of extremely annoying eyes. After seeing that smiling expression, Lin Wei suddenly felt very uncomfortable, she unconsciously raised her legs, and at the same time secretly glared at that place.

Li Huayong laughed silently, today Lin Wei wore a "Lin Group" work clothes, and the hard hat on his head was worn very well.

What's more, "Director Lin" didn't wear high heels today.

Lin Wei continued to bury his head in the record, gritting his teeth while recording, and said in his heart What kind of person is this, Uncle Quan also praised him for being very capable. What can he do, this is obviously a pervert, everyone has already warned him, and he dares to stare at others unscrupulously.

Just when Lin Wei couldn't bear it anymore and was about to warn Li Huayong again, she suddenly realized that something was wrong. She found that Li Huayong was indeed staring at her, and his eyes were also full of heat, looking like a standard color embryo. It's just that he doesn't seem to be looking at himself.

He was looking at the instrument beside him.

Li Huayong did look at the instrument with fiery eyes. This is a total station.

Total Station: The full name is called ElectronicTotalStation, which is a high-tech measuring instrument integrating light, machinery and electricity, and is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (oblique distance, flat distance) and height difference measurement functions. Compared with the traditional optical theodolite, the total station replaces the optical dial with a photoelectric scanning dial, and replaces the artificial optical micrometric readings with automatic recording and display of the readings, simplifying the operation of angle measurement and avoiding the generation of reading errors. Because it can complete all the measurement work on the station by placing the instrument at one time, it is called a total station.

All in all, a total station is much, much better than a traditional theodolite. The emergence of the total station can definitely be called a revolution in engineering surveying, which greatly reduces the difficulty of engineering surveying, and also greatly improves the precision and accuracy of engineering surveying. From a certain point of view, the emergence of the total station has also greatly improved the construction level of the whole human being, such as the "Bird's Nest" kind of building, if there is no total station, it is almost impossible to complete the positioning work of the project with an ordinary theodolite.

In Li Huayong's previous life, he first came into contact with total stations, and it was still in the work for several years, after the mid-nineties. Before that, let alone a total station, even a rangefinder with a simpler function was rarely used. But now it was only 1984, and Li Huayong vaguely remembered that the total station had just come out at this time, right? Now he actually saw the total station at this construction site, and it is no wonder that Li Huayong's eyes were full of heat.

In these days, engineering surveying is a hard job. For example, at this construction site, if you want to complete the positioning work, you can only use a theodolite with a steel tape measure. This method is not only cumbersome, but also very limited by the site. Just like the last dozens of piles, the positioning work was originally done a long time ago, and the reason why it was delayed until yesterday was because the site in this area was not flat enough, and there was no way to pull the steel ruler. It took a lot of manual work to clean up the site, and the work was barely completed yesterday.

"Alas, if there was a total station on the project, then I could have slept a few more times ago... No, no, I didn't see that Party A had this instrument some time ago, this should be this chick just brought from Xiangjiang, right? Tsk, good guy, this is actually a German Zeiss, not a more common devil goods, this one has to be hundreds of thousands bigger, right? Zeiss instruments are much stronger than devil goods, luxury, really luxury... Huh, this chick can speak German scolding again, and likes to use German goods, is this chick... ”

Just when Li Huayong was thinking about it, Party A's inspection work seemed to have been completed, and Lin Wei walked in front of Lei Jianjun and Xia Minghuan:

"Manager Lei, Mr. Xia, our retest results have come out, the deviation of this batch of pile foundation positioning is generally relatively large, and the maximum deviation of one pile foundation has reached 8 cm, what do you say to do now?"

I heard that there was such a big deviation, whether it was from the project manager Lei Jianjun to the project chief engineer Xia Minghuan, or from the engineering minister Deng Chaoqun to the project measurement engineer Da Lao Yang, all of them became very ugly.

In the whole building construction, although the engineering survey can only be regarded as an auxiliary functional department, it is undoubtedly a very important department, because the measurement positioning is nothing else, in any project, in this link of the error, it can be called a major quality accident.

Among them, especially the project surveying engineer Da Lao Yang's face became the most pale:

"I... Retest it right away and rectify the mistakes... ”

In Li Huayong's ears, Lin Wei's yin and yang weird voice came, and Li Huayong even noticed that when "Director Lin" said this, he glanced at himself intentionally or unintentionally:

"It's just these piles, after all, we've checked it out, I'm just afraid... ”

Speaking of this, Lin Wei didn't continue, she pointed to the entire construction site with her hand.

As soon as she said this, the faces of Lei Jianjun and the others became more ugly, the black became blacker, and the white became whiter. Lin Wei's meaning now is very clear: Today, only a few dozen piles have been inspected, but what about the more than 700 piles that have been constructed or are under construction in the past? Are there any problems with those piles?

At this time, Li Huayong finally couldn't listen anymore, he ordered the pillar to find a stake, took a small hammer, and walked under the sun umbrella, he ignored Lin Wei, and said directly to the Xiangjiang man who operated the total station:

"Master, what did you just say is the biggest deviation, I'll go and rectify it now. ”

With so many people on the scene, the Xiangjiang engineer was still very cooperative, the total station was a total station after all, and the position of the pile was corrected in less than 5 minutes.

After laying the stake, Li Huayong got up, and he commanded the pillar as if no one else had it;

"Okay, now you go find some people to come over, find more people, let them stop what they are doing, and dig up all these piles first. Remember, be careful when digging, do a good job of guiding piles, and you must ensure that they are not offset after digging. ”

Hearing Li Huayong say this, "Director Lin" finally broke out, her pretty face was flushed, she glared at Li Huayong and said:

"You... What do you mean? You are barbaric construction, do you know, do you know what construction is according to specifications... ”

Li Huayong smiled at her:

"Director Lin, don't be angry, don't say it, since you talked about the construction specifications, I just wanted to ask about it... ”

Speaking of this, Li Huayong didn't wait for Lin Wei to speak, he turned his head to Deng Chaoqun and said:

"Minister Deng, do you remember what the maximum allowable deviation of the pile foundation is?"

"This... I'm going to go back and check it out... ”

"No need to check, if I'm not mistaken, the maximum allowable deviation of a single pile is one-sixth of the pile diameter, and the maximum allowable deviation of a group of piles is a quarter of the pile diameter, it should be like this, right?"

When Li Huayong said this, when everyone understood the meaning of Li Huayong's words, the faces of everyone in the project department returned to normal, and Deng Chaoqun said excitedly: "I'll check it right now." ”

Then he galloped away in high spirits.

Why is Deng Chaoqun so excited? The pile diameters of these piles inspected today are all more than 1 meter, and these piles have both "single piles" and "group piles"; even if all of them are calculated according to a single pile, if Li Huayong's words are correct, the maximum allowable deviation of these piles is more than 16 centimeters.

A deviation of only 8 centimeters, that's still far from it.

Deng Chaoqun quickly rushed back happily, and he shouted excitedly as he ran:

"That's right, that's right! Dispatch Li is right, the maximum allowable deviation of the pile foundation is indeed as he said... ”

Now it was Lin Wei's turn with a gloomy face.

The last person to come out to play the round was Lu Yuquan, the owner's representative.

"Lotus... Director Lin, I think we'll close the team today, right?"

After appeasing Lin Wei, Lu Yuquan glanced at Li Huayong meaningfully, and Li Huayong's heart jumped:

"Offspring, good, good... ”

When he said this, Lao Lu even patted Li Huayong on the shoulder.

Li Huayong said with a smile: "Mr. Lu, don't worry, we Huaxia Jianzong... Ensure that everything is constructed in accordance with the specifications. ”

"Good, good, hehe... ”

When the group of Xiangjiang people walked away, seeing that Lei Jianjun and the others were all relieved, Li Huayong's own face changed, and he grabbed the surveying engineer Yang Lao:

"Yang Gong, hurry up, we must retest these piles. ”
