Chapter 160

Huailai County is located in the northwest of HEB Province, on the north side of the Yanshan Mountains and in the upper reaches of the Yongding River, with a total area of ​​1801 square kilometers.It borders Yanqing, Changping and MTG Districts of BJ City in the southeast, Xuanhua and Xiahuayuan Districts in the northwest, Zhuolu County in the southwest, and Chicheng County in the north.Huailai County is a transportation hub connecting the capital and the northwest, and is the window of ZJK City to the outside world. Shacheng Town, where the county government is located, is 120 kilometers east of BJ and 87 kilometers west of ZJK City.

According to the overall construction period requirements, combined with the actual situation of the project and the characteristics of various majors and related supporting projects, the Beijing-Zhangjiakou High-speed Railway Four Electricity Project Headquarters of Zhongyuan Electrification Bureau Group Co., Ltd. has 4 specialized project departments and 1 central warehouse. Specialized projects The subordinate facilities work teams adopt the management and organization model of the shelf team for each specialty, and adopt the method of combining parallel and flow operations to organize the construction according to the start time and the different construction contents of each stage.

Among them, the three project departments of electrification, housing construction and disaster prevention are all located in Huailai County, and the sound barrier project department is located in Changping.In order to create a "high-quality project, intelligent Beijing-Zhangjiakou", combined with the Beijing-Zhangjiakou high-speed railway project scope and construction characteristics, innovative management mode, set up a production resource management center in Huailai, equipped with logistics management, inspection and testing, intelligent provisioning, cloud video scheduling Command and training, intelligent safety experience and other five major functions, fully guarantee the high-quality project.

At around 12 noon, Ren Shuxia and her party came to Huailai County. Feng Wannian checked the time and said with a smile:
"Mr. Ren, look, it's time for lunch. We didn't say hello to the project department in advance for this on-site investigation. Otherwise, we'll go to a local noodle shop to eat noodles!"

"Good relationship, good noodles!" Ren Shuxia replied with a smile.

"Then let's go to the local "Hometown Noodle Restaurant"." Zhang Quanwu said to the driver with a smile.

"My hometown oat noodle restaurant is located at the north of the intersection of Shifan West Road and Yongyi North Street. The oat noodles here are authentic, with many ingredients, generous portions, and the price is not expensive." Feng Wannian said to Ren Shuxia with a smile:

"Otherwise, let's try something new!"

"Okay, I'll just eat this noodles!" Ren Shuxia replied with a smile.

The four of them ate at this well-known local noodle restaurant. After a short rest, they drove to the project department at about two o'clock in the afternoon. In the large yard behind the project department.

Zhang Quanwu called Yang Xinqiang and Ji Deming, chief engineers of the electrification project department, respectively in the car.

So when Ren Shuxia and his party got out of the car, they saw two people, one old and one young, standing in front of the project department building from a distance, greeting each other with smiles.

"This is Yang Xinqiang, Chief Engineer of the Electrification Project Department!" Zhang Quanwu introduced to Ren Shuxia, pointing to the 1.8-meter tall young guy.

"Hello, Mr. Ren, welcome to the site to guide the work!" Yang Xinqiang hurriedly stepped forward to say hello.

"Hello, hello!" Ren Shuxia also smiled and held Yang Xinqiang's hand.

"This is Ji Deming, director of the Production Resource Management Center. If you have any questions, feel free to ask him!" Feng Wannian introduced.

"Director Ji, come today, you have to give me a lively science class on intelligent production resource management." Ren Shuxia asked Ji Deming with a smile.

"Mr. Ren's name, none of us know, isn't it you who led the scientific research project for this production line of intelligent pre-configured wrist-arm suspension strings?" Ji Deming, a 50-year-old veteran material expert, smiled. say.

"Is it easy to use now?" Ren Shuxia asked with interest.

"Whether it works or not, you can tell right away!" Ji Deming didn't want to say anything at this time, but brought them to the pre-configuration central area.

As soon as she walked into this spacious and clear pre-configuration center, the first thing that caught her eyes was the huge automatic pre-configuration production line of van-type wrist arm. Ren Shuxia looked at this tooling equipment: it meets the conditions of intelligent, informationized and automated production , can directly read the preconfigured parameters of the wrist arm, and automatically complete the processes of feeding, blanking, cutting, drilling, assembling parts, marking the arm information, etc., to achieve fast and accurate preconfiguration and assembly of the catenary wrist arm device, fully satisfying In view of the demand for intelligent high-speed railway construction, I couldn't help but ask the operator next to me:
"How long does it take to pre-configure a set of wrist arms now?"

Before the staff could answer, Director Ji said with a smile:
"Mr. Ren, send the pipes and required parts to the automatic pre-configuration platform of the catenary arm, measure the length of the arm, cut the pipes, sort the heads, transfer the pipes, locate the holes and put on the parts for fastening, 5 minutes It will be done in one go, and the homework will be completed automatically." At this point, Ji Deming glanced at Ren Shuxia enviously, and then said:

"Mr. Ren, the pre-configuration platform that you led to develop uses mechanization to reduce manpower, reducing the original 12 operators to 4, and realizes 'distributed processing and centralized work, aerial work on the ground, on-site construction factory work', etc. The transformation has greatly improved the safety and precision performance of the catenary wrist arm pre-configuration platform. It completes nearly 200 sets of wrist arm pre-configuration per day under full load, and the technical standard error of each prefabricated wrist arm is controlled within Within 1mm."

"I don't dare to be greedy for credit. Is this all due to Comrade Zhao Wei, the on-site technical director?" Ren Shuxia was very pleased, but said modestly.

Speaking of which, Ren Shuxia came not far away, in front of the pre-configured automatic production line of the sister flower hanging string, while looking at it, she asked the technicians who were debugging:
"Hello, how is the accuracy of this hanging string production line now? In a month or two, it will be time for it to show its power."

The young technician wiped the sweat from his forehead and replied with a smile:

"Don't worry, Mr. Zhao has already solved this problem at the end of last year. We have cooperated with Tsinghua University to create a simulation model, and the suspension string calculation simulation simulates the field model, catenary status and parameters after the suspension string installation, and verifies through simulation software. , optimize the calculation results of the hanging strings, and ensure one-time installation. At present, the simulation model has been preliminarily built and integrated into this production line. After hundreds of tests, the error is controlled within the range of ±1mm; while improving the accuracy Greatly increased productivity."

"That's good, that's good!" Ren Shuxia praised repeatedly.

Ren Shuxia squatted again in front of the pre-configured wrist and arm, carefully looking at the structure above, she suddenly asked:

"Minister Zhang, is this the simplified design of the arm used for the Chongli Railway?"

"Yes, Mr. Ren, the catenary of the newly built Chongli Railway adopts a simplified design, and the new parts are mainly composed of: new wrist-arm positioning device, new overall suspension string, new terminal anchor clamp, new contact line center anchor line Clamps, etc. The new wrist arm support and positioning device, through the use of hinge hoop connection and similar function combination scheme, improves the integration and integration of parts, the structure is more concise and reasonable, and the anti-loosening, wear resistance and reliability are improved. The main performance improvements are as follows: (1) The connecting parts are replaced by forging technology to avoid casting defects and improve product quality; (2) Compared with the original device, the number of parts for each device is reduced from 23 to 14, a reduction of 39%. ; (3) The number of thread pairs has been reduced from 30 sets in the original device to 13 sets, a reduction of 57%; the types of thread pair tightening torques have been reduced from 6 to 3, a reduction of 50%; through the improvement of the above three types of performance, effective It greatly improves the stability of product manufacturing, reduces the workload of catenary construction and installation, and facilitates operation and maintenance." Minister Zhang blurted out like an endorsement.

"Not bad, not bad!" Ren Shuxia praised Zhang Quanwu repeatedly after hearing Zhang Quanwu's introduction.

She pointed to the QR code on the side of the arm end and asked with a smile:
"What is the function of this QR code?"

"This is our project department's use of "Internet +" technology to create a "digital material management system" platform to realize the refinement, standardization, and Intensification, traceability and comprehensive closed-loop management." Director Ji Deming introduced with a smile.

Looking at Ren Shuxia's eagerness to understand the appearance of intelligent construction management, Feng Wannian smiled and said:
"Director Ji, why don't you bring Mr. Ren to visit your treasure room and let Mr. Ren see your top-secret weapon?"

"Okay, okay!" Ren Shuxia said as if Grandma Liu had entered the Grand View Garden, looking impatient.

When Ji Deming opened the heavy anti-theft door and turned on the lights in the room, Ren Shuxia saw a row of intelligent high-tech tools that he had only seen in books before: light digital display elastic sling installer, backpack type Electric connection crimping equipment, manual hydraulic bolt cutter, railway lithium battery high-speed cutting machine, high-speed iron lithium battery precision tightening system, wrist arm offset measuring instrument, rotary wire stripper...

Ren Shuxia couldn't help exclaiming at this moment:
"It seems that Mr. Mao has spent a lot of money in investing in machinery and tools!"

"That is, with these treasures, there are tool guarantees for improving construction accuracy and efficiency, preventing construction risks, and implementing high-quality projects." Ji Deming couldn't hide his inner joy at this time.

At this time, Ren Shuxia seemed to hear the exciting words of the commander Mao Shaohua at the 2019 construction plan mobilization meeting of the Beijing-Zhangjiakou High-speed Railway Four Electric Project:

"Our goal and task of creating a high-quality project intelligent Jingzhang is to create a new standard for the 2025 high-speed rail made in China, to achieve new development and new guidance. I am deeply honored to be able to participate in the construction of the Beijing-Zhangjiakou high-speed rail, but also feel the responsibility and pressure. I would like to work with all colleagues Work together, carry out the work in a down-to-earth manner, implement the "excellent engineering smart Beijing-Zhangjiakou", and work hard for the smooth realization of the goal of "making the Beijing-Zhangjiakou high-speed railway a model of high-speed railway in the world"!"

"It seems that the leadership of the group company has great strength and determination to build a smart Beijing-Zhangjiakou high-quality project. I have the honor to participate in the construction of the Beijing-Zhangjiakou high-speed railway. How dare I not work hard and strive for excellence." Just when Ren Shuxia bowed her head and meditated alone , Feng Wannian smiled and said to her:

"Mr. Ren, let's go, let me take you to experience VR security?"

"Okay, okay, okay!" Ren Shuxia said and came to the intelligent dispatching center with everyone. After she experienced it, she said with a sense:
"This set of equipment adopts VR virtual demonstration, together with sound effects, explanations and dynamic effects of the all-in-one machine, to conduct "immersive" training on accidents such as falling from heights, foundation pit collapse, mechanical injury, electric shock, fire, etc., which is really helpful for improving front-line construction. Personnel safety awareness helps a lot.”

"Mr. Ren, can you take a look at our AR-assisted construction system again?" Zhang Quanwu said, and handed a pair of glasses beside him to Ren Shuxia.

"This is?" Ren Shuxia asked inexplicably.

"Through the AR glasses, various drawing standards can be directly displayed in front of the eyes, and real-time solutions for on-site workers can be solved; at the same time, the real-time images can be transmitted back to the rear, enabling remote consultation with experts and providing support and assistance to the construction site," Zhang Quanwu explained with a smile. road.

"My God, it's amazing!" Ren Shuxia couldn't help admiring.

"Mr. Ren, I will take you to the scene tomorrow morning to see an even more powerful artifact!" Feng Wannian smiled mysteriously.

After this on-site survey, Ren Shuxia was really pleased that she was able to participate in the construction of the Beijing-Zhangjiakou high-speed railway. She said with a smile:

"What is the concept of intelligent railway: it is the extensive application of new technologies such as cloud computing, big data, Internet of Things, mobile Internet, artificial intelligence, Beidou navigation, BIM, etc., comprehensive and efficient use of resources, and the realization of high-speed rail mobile equipment, fixed infrastructure and internal and external environments. Comprehensive perception of inter-information, ubiquitous interconnection, integrated processing, active learning and scientific decision-making, and a new generation of intelligent high-speed railway system that realizes integrated management of the entire life cycle. Realize safer, more reliable, more economical and efficient, more warm and comfortable, and more convenient Faster, more energy-saving and environmentally friendly goals."

Having said that, she paused for a while, looked at everyone affectionately, and continued:

"It seems that the leaders of our group company and the Beijing-Zhangjiakou High-speed Railway Four Electricity Headquarters have fully understood the concept of this intelligent railway, and have already applied it to the front-line construction management. "Construction" scientific research project has found its scientific and technological innovation experimental field here?"

That night, a group of four of them checked into the guest house of the project department. Ren Shuxia lay on the bed, her mind kept replaying the magical artifacts that Mr. Feng said during the day, and her curiosity made it difficult for her to sleep all night...
