The matter of Nancheng Nanyuan has finally come to an end, and there is still a lot of work to follow-up, but the general principle has been decided, and the next thing is to implement it! Jiang Xiaoxiao, Lu Defei and Ming Xinyu haven't looked for Chen Qiang for a long time, have they already decided that Chen Qiang and Secretary Chen have no relationship, or they don't need to find Chen Qiang to do anything for the time being, and Chen Qiang has been clear for a short time!

In the early spring, the city often ushers in some bright sunshine, the willow trees in the Luannan District Government Square have sent out new shoots, and Chen Qiang has accepted a new job in the new year - supervising physical testing! In addition to the supervision of the construction process, the work of the quality supervision station also needs to selectively participate in the physical testing of the main project, such as the physical detection of concrete strength, the thickness determination of the protective layer of reinforcement, the determination of masonry strength, and the emergence of the finely decorated room, some air detection content has also been added! However, for the safety of the building structure, the most important thing to test the main engineering entity is the concrete strength (both reinforced concrete structure and brick-concrete structure are required) and mortar strength (mainly brick-concrete structure)!

In the past, the physical inspection of the main project was selectively participated, but later, in order to strengthen supervision and there are more young people in the station, the station requires that the physical inspection of the main project of each project must send people to participate!

The first main engineering entity inspection project that Chen Qiang participated in the New Year was a project in Nanhua Town, Luannan District - Nanhua Commercial Building! It is said that it is a commercial building, in fact, it is a six-story single building, because Nanhua Town is located in the southernmost part of Luan District, the level of economic development is low, and the business atmosphere is not strong, so there is no decent commercial project in the town! Later, a boss surnamed Zeng who went out to do business in Nanhua Town returned to his hometown to renovate a dilapidated temple in the core area of Nanhua Town and build a Nanhua commercial building!

In order to control the cost, Boss Zeng chose the design scheme of the brick-concrete structure, because the project is relatively simple, Mr. Yang took Wu Cheng and Chen Qiang only to accept the foundation pit and foundation engineering, and when he went later, the Nanhua Commercial Building was directly built! According to the requirements, Chen Qiang followed the staff of the testing institute to conduct a physical test on the Nanhua Commercial Building!

The core content of the brick-concrete structure inspection is the mortar strength and the concrete strength of the structural columns and ring beams! The floor of Nanhua Commercial Building is not high, the design strength of the mortar is M10, and the design strength of the concrete part is C25! The main instruments used for testing are mortar rebound tester and concrete rebound tester!

If the testing process goes well, it can be completed in half an hour, and the testing point will be spot-checked immediately! Chen Qiang and the staff of the testing institute selected three mortar and concrete testing points on the first floor, and several points on the second floor, fourth floor, and sixth floor! The test results of the concrete part are ideal, the rebound value is about 30, and the test results of the mortar part are a bit problematic: first, the error is relatively large, the largest value is about 15, the small is about 7-8, and the second is that the overall data is small, basically below 10, the on-site personnel judge according to experience, the mortar strength is definitely unqualified through the rebound test, and further testing is needed!

Chen Qiang didn't think that the first work of the new year and encountered a sudden problem that he had not been exposed to, Chen Qiang's first reaction was that Nanhua Commercial Building was likely to have quality defects and needed further testing, and the second reason was that the strength of the mortar was not enough was very strange, because the strength of the concrete was in line with the requirements of the specification, the strength of the mortar part was mainly to bear the weight, the volume of the project was not large, and the total amount of mortar was not large.

Chen Qiang hurriedly called Mr. Yang, and Mr. Yang and Wu Cheng hurried to the scene by car after receiving the call. Mr. Yang asked Chen Qiang to call Boss Zeng over and asked about the construction process, and Mr. Yang's expression became more solemn after listening!

It turned out that the boss was a native of Nanhua Town, and he came back to invest in repairing the house soon his fellow villagers knew, he couldn't save face, so he handed over the project to a relative in the same township for construction, although the unit attached to this relative is a regular enterprise, but the actual construction people are all local migrant workers, that is, the kind of workers who were farming yesterday and started building houses today! It is conceivable what the quality of such a house will be!

Mr. Yang hurriedly called Wu Cheng and Chen Qiang over, and asked them to immediately put forward the construction procedures of the project to take a look, and when he saw the information on the construction procedures, Chen Qiang gasped, the project construction unit: Nancheng Construction Division, project manager: Lu Defei! The companies and people affiliated with this project are still not simple! Chen Qiang also felt strange, he hadn't seen Lu Defei the first two times he came to the scene, and he couldn't imagine that the project manager was actually him! It seems that the affiliation of the construction industry in Luannan District is indeed relatively common, and such a remote project is actually affiliated with the most influential construction unit and project manager in Luannan District!

"Wu Cheng, you call Lu Defei immediately and inform him to come to Nanhua Town!" Teacher Yang said to Wu Cheng!

"Okay, Mr. Yang!" Wu Cheng replied!

"Chen Qiang, notify the designer and supervisor to rush over! Forget it, don't be in a hurry to inform them to come over, you go and find out the phone number of Li Yang, the chief engineer of the Luancheng Institute of Construction Science and Technology, I will contact him later! ”

"Okay, Mr. Yang!" After Chen Qiang answered, he immediately went to look through Li Yang's phone!

Chen Qiang used his mobile phone to dial Li Yang's phone, and then gave the phone to Mr. Yang, Mr. Yang picked up the phone and walked to the side to talk to Li Yang, Chen Qiang and Wu Cheng did not follow, it was obvious that Mr. Yang was verifying and communicating something!

After about forty minutes, Mr. Yang's phone call had already ended, and Lu Defei rushed to the scene!

"Yang Gong, what's wrong with Nanhua Commercial Building?" Lu Defei asked!

Teacher Yang showed Lu Defei the test data, and then said:

"Manager Lu, you have too many projects in your name, can you manage them? You can see the quality of the project in Nanhua Commercial Building, and then come and talk to me! Teacher Yang said!

Lu Defei hurriedly went to the project site and walked around, buckled the mortar with his fingers, checked the flatness of the masonry and the construction quality of the concrete, and then ran back to Mr. Yang!

"Mr. Yang, although this project is very biased, but I still excluded a technical person in charge of my work to see, although the quality can not be compared with the core area of Luannan District, but overall it is still good! It may be that the strength of the local mortar is a little low, which may be related to the construction level of the workers, or it may not be evenly stirred or the cement mortar ratio is somewhat off! Lu Defei explained!

"If you also find a problem, it's easy to say, let's talk about how to solve it!" Teacher Yang said!

"Chen Qiang, inform the design and supervision to come over immediately!" Teacher Yang said!

Chen Qiang hurriedly called the person in charge of the design and the director of the supervision company and informed them that they must come in person, otherwise they will bear the consequences!

The scene of Nanhua Commercial Building was silent for a while, Lu Defei looked very anxious, he didn't know how to deal with Mr. Yang, he felt that this matter was not very complicated, it should be solved soon, he had already thought of a countermeasure......
