Xiuli Zhao's advanced deeds

In 2005, after concentrating on scientific research and development, and on the basis of digesting and absorbing German technology, she realized the innovation of the production process of type II track slab of China Railway Second Bureau and the localization of the design, production line and model of non-state-owned steel bar factory, which filled the gap of this technology in China and laid a solid foundation for China Railway to enter the high-speed era. At present, her technical development plan of "vigorously promoting independent innovation, mastering core technologies and taking the road of technical management development" shows the wisdom of China science and technology workers in the development process of China Railway Type II track board from "zero" breakthrough to "Made in China" and then "Created in China".

1. In the inter-city construction between Beijing and Tianjin, she opened a new era of "Made in China" for ballastless track slabs.

The production technology of ballastless track slab is imported from Borg company in Germany, and the raw materials needed for production are quite different from those in China. Comrade Xiuli Zhao knows that this problem can only be solved through independent innovation. In order to trial-produce cement that meets the requirements of German standards, she and the manufacturer tried again and again. In order to realize the production and supply of non-national standard steel bars, she jointly developed with manufacturers; In order to develop the standard concrete mixture ratio, hundreds of tests have been carried out in person. At the same time, she also worked with QC team to realize 64 rationalization suggestions, saving 654.38+0.5 million yuan; More than one major technical breakthrough 10 was achieved, and 38 technological equipment improvements and construction method innovations were made. She digested and absorbed German technology, realized the localization of track slab yard design, superfine cement, equipment and models, non-national standard steel bars and other technologies, and was recognized as "international advanced", and was recognized as seven innovations by the Academy of Iron Sciences, filling the domestic gap.

Second, in the construction of Beijing-Shanghai high-speed railway, she interpreted a new chapter of "China Creation".

Aiming at the problem of high price of superfine cement for track slab production, this comrade replaced composite admixture with ordinary admixture, innovated the mix proportion of track slab concrete, and developed a veritable "green high-performance concrete", which reduced the cost of each track slab concrete admixture by more than 300 yuan and saved more than 30 million yuan for the Beijing-Shanghai and Tianjin-Qinhuangdao projects of China Railway Sixth Bureau. At the same time, she broke the limitation of "German model" and changed the traditional Z-shaped production line of track plate into a concave layout, thus reducing the floor space; The base flow process is changed to process flow process, saving half the time; The engraving process of CNC grinder is separated from the grinder, and the grinding time of each plate is shortened by 20%. The new end seal disassembly tool developed has applied for national patent, etc. Many scientific and technological innovations are widely promoted because they are simple, effective and cost-saving.

Thirdly, in the construction of high-speed rail in China, she has built a huge team of track board experts.

This comrade studied his business assiduously, searched for information at home and abroad, and mastered the most advanced construction method of type II track slab in the world. She participated in the preparation of "CRTSⅱ Ⅱ Ballastless Track Slab Long-line Pedestal Manufacturing Method", which won the ministerial-level construction method of the Ministry of Railways; Her invention, "a mold removal tool", won the national utility model patent; The Pinggu Track Plate Factory, which she participated in, has three production lines of Type II track plates, and is the largest track plate production, training and R&D base in China designated by the Ministry of Railways. At the same time, she taught the track slab technology she mastered to the technicians around her and her domestic counterparts, which enabled the track slab technology to be rapidly popularized and trained thousands of track slab technicians for China's high-speed railways.

Xiuli Zhao sacrificed too much for the high-speed rail career she loved and the team she loved ... She never mentioned the word "home" in front of people, because "home" would make her feel guilty. When she heard the news of her son's admission to the college entrance examination, she smiled with relief at the busy scene, but her eyes were wet.
