The same two bridges, the design drawings are similar, the design materials are basically the same, but in the actual construction process, the same columns, two sections of different materials, one in strict accordance with the design drawings construction, the other is to steal beams to change columns, the use of slimming materials.

The so-called "slimming steel bar" refers to the construction units of some illegal construction industries, not using steel bars according to the design drawings, but reducing the diameter standard of materials, or stretching the normal steel bars and then using them for housing construction, in order to reduce construction costs.

Some experts pointed out that the use of slim steel bars that are not designed drawings and the use of thin steel bars instead of thick steel bars in design drawings will lead to a serious decline in the quality of the project; The use of elongated steel bars, after the steel bar is elongated, the original extensibility is destroyed, breaking through the tensile safety limit, once an earthquake occurs, the building is easy to collapse. In addition to the decrease in earthquake resistance, the load-bearing capacity of the house will also decrease, and the higher the building, the more serious the hazard.

It is no wonder that Mayor Jiang Guoqing is angry and wants to continue the construction according to this construction site, it is not good to say, this overpass is a tofu scum project.

Looking at the round steel wires scattered on the ground, all the traces that have been stretched are clearly visible.

Mayor Jiang Guoqing calmed down and said sharply to the construction manager who followed,

"Now you show us the design drawings of this bridge, what the hell is going on?"

Several engineers hurriedly brought the design drawings, unfolded them, and showed them to the leaders.

Everyone looked at it, the design drawings were written in black and white, and it was clearly marked that the steel bars used in all the columns of the bridge were 32 mm diameter three-level rebar with high standards of shockproof shockproof, and the 32 mm rebar was connected to a 10 mm disc around the perimeter.

"Director Wang, look at it, how big of steel is used for this column now?"

Mayor Jiang Guoqing asked Wang Jianxing, director of the construction committee who was looking at the drawings next to him.

Director Wang is a veteran of the Construction Committee and an old subordinate of Vice Mayor Li Mingguo.

Director Wang said confidently,

"Mayor Jiang, you are always testing me, as far as I can see, it may be 25 mm in diameter."

"Not bad! Lao Wang, worthy of being an expert of the Construction Committee, then tell me how big is the current reinforcement? ”

"This one is definitely not 10 mm, it is obviously stretched, I think it is at most 8 mm."

"I think it's about the same, Mayor Li, what do you say?" Mayor Jiang Guoqing asked Li Mingguo rhetorically.

At this time, Vice Mayor Li Mingguo's face was obviously unnatural, and he said softly,

"Mayor Jiang, Director Wang is right,"

Mayor Jiang Guoqing ignored Li Mingguo's feelings and said to several managers at the construction site,

"Is your site supervisor there?"

"Mayor Jiang, I am," a person squeezed out of the crowd and said to Jiang Guoqing.

"Look, everyone, something so big, you still have a pestle there, do you know how these materials are used?"

"I... I... I don't know,"

"As a supervisor, you are derelict in your duties, what kind of behavior is it, Director Wang, Mayor Li, the problem of this construction site is here, you can take a deal with it."

Mayor Jiang Guoqing directly handed over the problem to Li Mingguo and them.

"Mayor Jiang, cut corners, use materials with specifications smaller than the design drawings, and use elongated steel bars, obviously to save costs and build a tofu slag project, I suggest ......" Director Wang was stuck at a critical moment.

"Director Wang, what do you suggest?" Mayor Jiang Guoqing asked.

"Mayor Jiang, I think we will investigate and verify it again, what is going on, and then deal with it?" Li Mingguo was a treacherous man, and actually replied like this.

"Mayor Li, what's wrong with you! Isn't it clear what is so clear at a glance? Can't everyone see it? Director Wang, you go on, how to deal with it? ”

Mayor Jiang Guoqing said loudly.

"Mayor Jiang, the work should be stopped first, and our construction committee will investigate and verify before making a conclusion."

"Okay, Director Wang, just do as you say, however, the comrades of the municipal government office should also participate in the investigation team, to be honest, seeing that the management of this construction site is so chaotic, it should also be stopped for investigation."

After Jiang Guoqing finished speaking, he said to the officials and reporters of the TV station,

"Comrades, the quality of the project is life, the use of materials is not in accordance with the requirements of the design drawings, that is, life is regarded as child's play, such a project is what the former prime minister said, it is a tofu scum project, it is a bastard project, I hope that the construction team of the project, keep in mind, do not let the people point to the backbone and scold."

"Yes, comrades, you have seen that such a construction site, the management is not standardized, and the use of slimming steel bars in front of the public, is simply to regard our urban construction department as nothing, regardless of the safety of people's lives, such a construction site, our municipal government will not sit idly by, the suspension is certain, we will also implement the spirit of Mayor Jiang's instructions, the quality of the construction site to the end."

Secretary General Liu, the secretary general of the municipal government, who has been silent, on the one hand, took a good look at the urban construction department led by Vice Mayor Li Mingguo, and on the other hand, he invisibly patted Mayor Jiang Guoqing's ass.

Then, the law enforcement brigade of the urban construction committee temporarily stopped the construction site, that is, the construction site of Jiangcheng Shengtian Road and Bridge Construction Co., Ltd. was temporarily not allowed to start construction, and a decision was made after the investigation team verified the situation.

As we all know, the pursuit of high profits by engineering greed is the main reason for the "slimming" of steel bars. In fact, the current steel slimming is not very serious.

After 2010, it was a period of great explosion of slimming steel bars.

In the exposed Jiangcheng "slimming steel bar" incident, there are no less than 100 slimming steel processing points, and the "industry" of over-drawn steel bar has been quite large-scale, and the "slimming" of steel bar has become the "unspoken rule" reached by some greedy people in this industry in pursuit of high profits.

Experts in the construction industry have calculated that the prescribed weight of 10 mm steel bars per meter is 0.618 kg, that is, 1 ton of steel bars should be 1620 meters, and from 10 mm to 9 mm, one ton of steel bars becomes a full 2000 meters. By multiplying the 380 meters of steel bars that "grow" in the middle by the weight of 0.4998 kg per meter of 9 mm bars, it can be calculated that a ton of steel bars pulled from 10 mm to 9 mm will "more" 190 kg. According to 4,000 yuan per ton of steel, 190 kilograms of steel bars are worth 760 yuan, which is the "cat greasy" earned by processing plants and builders. Therefore, there is a huge profit implied in each "0.1 mm" of illegal elongation.

At the construction site in front of us, the illegal use of steel bars with a diameter of 25 mm instead of the steel bars with a diameter of 32 mm in the original design drawings is even more amazing.

This is a complete outright robbery.

The leaders of the onlookers thought in their hearts that if it had not been discovered by Mayor Jiang Guoqing, the construction site would continue to be built, and the profits of materials would have been quite considerable.

All the officials and reporters applauded Mayor Jiang Guoqing's speech, but only Li Mingguo was not happy in his heart, and everyone's applause seemed to be beating his heart every time.
