As the car went down the bridge, Tao Guangming's tense body gradually relaxed.
Tao Luyao, several experts, and the construction team leader arrived and were waiting for them on the roadside below.
Tao Guangming felt like he was surviving a disaster. His eyes turned red when he saw Tao Luyao: Dad, crossing this bridge was so scary. I almost died on it.
Tao Luyao's expression was calm, and he only made brief eye contact with Tao Guangming when he got out of the car.
He wanted to see the clues from Tao Guangming's face, but Tao Guangming had already regained his composure.
Tao Guangming has been with Li Wenjun for a long time, and has learned the ability to pretend to be nonchalant no matter what happens.
The leader of the expert team said: "Comrade Li Wenjun, if you want to confirm whether these pillars meet the requirements, you can only break open the layer of concrete outside the pillars, but then the pillars will no longer be usable. It is really embarrassing."
Li Wenjun took out the concrete steel bar detector and said, "I invented a new instrument that can directly measure the distribution and damage of internal steel bars without destroying the building."
Experts also know Li Wenjun's abilities. Since he can invent walkie-talkies and pagers, and successfully build base stations and paging stations, it is easy to make such small instruments.
The experts surrounded Li Wenjun, took the instrument and looked at it curiously.
Expert A asked: "What is this principle?"
Li Wenjun: "The transmitting coil is excited by a large current to generate a pulse magnetic field. The steel bars will generate eddy currents under the excitation of the pulse magnetic field to generate an induced magnetic field. The receiving coil converts the induced magnetic field into an electrical signal and inputs it into the host computer.
The computer analyzes the electrical signal in real time and determines the distribution of internal steel bars based on this."
Expert B: “What are the usage restrictions?”
Li Wenjun replied: "It requires a large current, so it needs to be equipped with a large battery. It would be better if there is a power supply on site. There should not be strong alternating electromagnetic fields around it, such as large electromagnets and transformers; this is obvious. The ambient temperature is minus ten
Between degrees Celsius and 40 degrees Celsius, the relative humidity is less than 90 percent."
Expert C: "How high is the accuracy?"
Li Wenjun: "More than 99 percent of the time, the calibration results can be measured multiple times. You can also use an object with a known number of steel bars to calibrate."
Expert Ding: "Hey, this is easy to handle. There are a lot of abandoned reinforced concrete piles from previous road construction. You can check them and you will know."
Expert E: "Let's go and try it. If this instrument works, I will order one with Comrade Li Wenjun now. We need this instrument so much. It can be used for flaw detection and acceptance inspection."
Expert A: "Yes, I need it too."
Several experts were like children getting a novel toy, and they couldn't wait to take the instruments and measure them around a pillar with exposed steel bars on the roadside.
Turn on the instrument and point the probe of the instrument at the pillar. After a few beeps of "bibibi", wavy lines will be displayed on the screen of the instrument, and then a steel bar distribution map will be displayed on the screen.
The expert changed the direction and measured several times. Finally, the instrument calibrated itself and produced a distribution map of the steel bars. Because the actual situation is right in front of you, you can see at a glance that the instrument measurement results are very accurate.
The experts sighed and tested another one, and the results were equally accurate.
After five or six consecutive tests, everyone believed it.
While the experts were measuring the pillars, Tao Luyao asked Tao Guangming and Li Wenjun: "What's going on?"
Li Wenjun whispered a few words in Tao Luyao's ear.
Tao Luyao's face turned cold, he pursed his lips and whispered: "If the situation is true, they have gone too far. They even used people's lives and the country's property to achieve their own ulterior secrets. I will definitely get to the bottom of it."
If what Li Wenjun said is true, this is tantamount to giving the Tao family a good opportunity to defeat the Kong family. How could he, Tao Luyao, let it go?
As a conscientious person, it is impossible to let such a person who kills people for profit escape.
------
One of the experts over there took the construction drawings and as-built drawings, and another person was responsible for using instruments to measure the pillars one by one from the foot of the viaduct to the location close to the mountain.
Everything was fine in the front, but when we got to the middle one, the experts stopped.
The steel bar distribution map measured by the instrument is clearly different from the as-built and construction drawings. A few bars are missing and the spacing is widened.
This is a common method of cutting corners.
If Li Wenjun knew it, he knew the law and broke the law; if he didn't know it, he was framed. But no matter which case it was, Li Wenjun would be responsible in the end.
This time Li Wenjun is dead!!!
The experts exchanged glances and remained silent together in a tacit understanding. They were afraid of making mistakes, so they repeated the measurement several times, but the results were the same. Then they marked the pillars and drawings, and someone copied the distribution map on the instrument, and then continued.
Test down.
The captain of the construction team, who had been following the experts, saw the silent exchanges between the experts but did not say anything.
After measuring all the pillars, the expert said to Tao Luyao: "Leader, we have a few words to say to you alone."
Tao Guangming became more and more nervous and wanted to follow him involuntarily, but Li Wenjun grabbed his arm and stopped him.
The construction team leader also silently stopped in the distance.
-----
The leader of the expert team called Tao Luyao aside, took out the drawings drawn after the measurement and said: "Leader, the actual number of steel bars in the bridge piers is less than the as-built drawings and construction drawings."
Other experts also said: "This is cutting corners."
"The problem is serious."
Tao Luyao sneered secretly: What Li Wenju said is actually true.
He asked calmly: "How much less will it affect the strength of the bridge?"
The leader of the expert team was silent for a moment before replying: "About ten percent. Whether the strength can meet the requirements requires detailed calculations. You can't tell by just looking at it this way."
Tao Luyao nodded: "Okay, please let some experts check it and tell me the result."
He raised his hand and called Li Wenjun, Tao Guangming and the construction team leader over.
Li Wenjun still looked calm, but Tao Guangming looked calm and determined to die.
Tao Luyao said: "After testing, experts found that the steel bars on several piers were 10% less than those on the as-built drawings. Do you have any explanation?"
Li Wenjun deliberately pretended to be surprised: "How could that happen?"
He pondered for a moment and glanced at the captain of the construction team: "Captain, do you have any explanation?"
The captain of the construction team said: "Eh? Comrade Li Wenjun, you obviously asked me to reduce the amount of steel bars. Why are you asking me again?"
Li Wenjun sneered: "I have a detailed record of the amount of steel bars used here. It shows that you collect the amount according to the construction drawings every day, and you have never received less. Now you are slandering people and saying that I asked you to reduce the amount of steel bars, right?
