Chapter 162 Precise Measurement
When Ren Shuxia and his party walked in, it turned out that they were the measurement team of the electrification project department of the Beijing-Zhangjiasi Electric Engineering Project.Several staff members in orange overalls, with dark skin, and a big fat boy was holding a measuring instrument with his hands and was measuring there.

Their task today is to divide the three known elevation points into two sections of one kilometer each, and each section contains about 40 elevations of catenary foundations for closure.

When measuring the first one-kilometer section, the error was 21 millimeters.

"Foreman, there is an error of 21 millimeters in the first one-kilometer section." The chubby boy in the team reported to the foreman Xu Weiming as usual.

"The foreman, are we going to carry out the second one-kilometer measurement now?" After waiting for a while without hearing Xu Weiming's voice, the little fat boy couldn't help asking with urging.

At this time, Xu Weiming bowed his head and said nothing, standing alone by the track, thinking carefully, and suddenly thought that 5 years ago, he had just learned to use the instrument, and the error of such a measurement work was only 21 millimeters. Five years have passed, and now I am working on the Beijing-Zhangjiakou high-speed railway, a high-quality project, or the same measurement, can't I do better?Thinking of this, he raised his face and simply popped out three words: .

"Retest."

When the surrounding team members heard his words, they couldn't help being stunned, Xiaopang murmured disapprovingly:

"Although 21 mm is slightly higher, it is within a reasonable range." In fact, most of the players around me think so.

Xu Weiming didn't say any more, he just squatted down and began to check the data with his head down.

"There is no problem with the data. If the error is too large, the data will be invalid." Xu Weiming straightened up and ordered:
"Little Fatty, you can change the instrument on the car. Big guy, you and Little Fatty can switch and measure again!"

Xu Weiming changed the measuring instruments and personnel, and restarted the measurement.

Little Fatty's measurement speed is much slower than before.

After more than an hour, the data came out.

Still 21mm.

"It shouldn't be!"

"it's wired……"

"There is no problem with the known elevation points here. How can the error remain the same after changing personnel and instruments?" The big man expressed the common doubts of everyone.

Originally, I still thought about changing the instruments and personnel, basically eliminating the root cause of the error, and the error result should be reduced, but unexpectedly, it was still the same.

"However, foreman, this error is only one millimeter away from the error range you requested, which is not much. Otherwise, let's measure the next section first..." Xiaopang already showed an impatient expression on his face, and raised his tone Said.

Xu Weiming remained silent, he lowered his head and continued to study the "1 mm".

"There is no problem with the instrument, there is no problem with the person, and there is no problem with the known points..." Xu Weiming did the elimination method in his heart, and his eyes lingered on the measurement drawings.

Suddenly, out of the corner of his eye, he caught sight of Tafoot.

This is a measuring ruler similar to a fishing rod, which can be shortened or stretched. There is a buckle between the upper section and the lower section for fixing.

He picked up the tower ruler and glanced at it, his eyes locked on the buckle on the tower ruler, and he had an idea in his mind.

He took out the national standard tape measure, fixed the buckle, and then measured the length together.

The numerical difference of one millimeter is in front of everyone.

Xu Weiming understood, and the onlookers showed expressions of sudden realization.

"Big guy, go to the car and fix the tower ruler with tape to ensure that it is accurate and firm. Everyone else is in place, and we will test it again."

For the third measurement, time seemed to pass quickly.

At the last step, the team members gathered around Xu Weiming.

"20mm." Xu Weiming exhaled lightly and concluded.

The crowd cheered.

Ren Shuxia looked at the group of young surveyors, and couldn't help being moved by their rigorous work and professionalism with a millimeter tolerance. She stepped forward and asked with a smile:
"Mr. Xu, on behalf of the Beijing-Zhangjiakou High-speed Railway Sidian Command, thank you and applaud you for this millimeter!"

"Are you?" Xu Weiming looked at the middle-aged woman in front of him suspiciously and asked anxiously.

"Stinky boy, this is Comrade Ren Shuxia, chief engineer of our headquarters!" Feng Wannian introduced with a smile beside him.

"Hello, Mr. Ren, Mr. Ren!" The surveyors around him shouted in one voice.

"Minister Zhang, I'm not talking about you, do you usually care little about the work of the surveying team, and their measuring instruments must keep up with it?" Ren Shuxia suddenly asked Zhang Quanwu seriously.

"Mr. Xu, there is a quality problem with the measuring instrument. You should report it in time. I promise that such problems will not happen again in the future!" Zhang Quanwu grinned and said to Xu Weiming with a smile.

"Then thank you, Minister Zhang, I will look for you tomorrow!" Xu Weiming said shrewdly.

"You boy, everything you do is in a hurry, okay, I'll give you the spare tower ruler from the engineering department first!" Zhang Quanwu smiled wryly.
