In the context of traditional Chinese culture, the ox is a symbol of selfless dedication, pioneering spirit, hard-working and hard-working, "Ruzi Cow", "Pioneer Cow" and "Old Cattle" are well-known beautiful images, is a profound cultural image, contains the spiritual code of Chinese sons and daughters of self-improvement and forge ahead.
Practice the spirit of "three bulls" and strive to be the pioneer of state-owned enterprises. In 2023, the "'Three Cows' Pioneer" of Jinan City's state-owned enterprises was released, and three comrades of the group were rated as "Pioneer Cattle" pioneer individuals - Liu Wei, Zhang Kun, and Meng Xiaoning. In the early stage, the typical deeds of Zhang Kun have been introduced, and today the story of "Pioneer Cattle" pioneers Liu Wei and Meng Xiaoning "pioneering and innovating and striving for the first" is published.
Liu Wei: "Chuang" is the first word, write a new chapter
When he took over the task of building the Jilai high-speed railway, Liu Wei actually didn't know what kind of burden was in front of him. The construction of high-speed rail is a new challenge for subway people, especially the shallow buried bias of the tunnels along the Jilai high-speed railway, the complex situation of railways and roads, and the construction tasks are arduous and difficult.
In the face of a professional field that he had never been in contact with, Liu Wei led a young team with an average age of 34 years old to continue to explore and boldly practice, and successfully completed the construction task of Jilai high-speed railway with the courage to open roads and build bridges in the mountains.
They continue to innovate in the project construction management, organize and carry out tooling process transformation, promote the application of 22 tooling processes such as complete sets of tunnel lining construction technology across the line, strictly implement the requirements of "tooling and process quality", and adopt a series of efficient management measures such as first article evaluation, model guidance, 100% process licensed acceptance, and random inspection by the safety and quality inspection team, so as to effectively improve the quality of project construction and set a benchmark for the quality of new high-speed rail projects in the province.
In the more than 1,200 days of the construction of Jilai high-speed railway, Liu Wei led the team to gradually grow from "industry novice" to "expert", they took the initiative to learn advanced experience, and successfully overcame many problems such as the difficulty of karst fissures to develop into piles, the complex and changeable geological conditions of tunnels, and the complex structure of station pipelines, and broke through the "bottleneck" of multiple engineering construction, and achieved 7 times across the expressway, 4 times across the high-speed railway, The 27 long-span continuous beams were successfully closed, making every effort to ensure the opening and operation of the Jilai high-speed railway as scheduled, helping the operation mileage of the high-speed railway in Shandong Province to successfully leap to the forefront of the country, and fully demonstrating the responsibility and responsibility of the "iron army" of Jinan rail transit.
Jilai high-speed railway is known as the encyclopedia of China's high-speed rail construction, Liu Wei and the majority of builders with the great "pioneer cow" spirit, wrote a wonderful chapter of exploration and enterprising.
Meng Xiaoning: Innovation-driven, brave to be the vanguard
In 2017, Jinan Heavy Industry, which is in the process of transformation and upgrading, set up a team to start independently developing the shield machine, and Meng Xiaoning, who has been engaged in the research and development and design of tunnel boring equipment, took the initiative to ask for help and provoked the research and development burden of the main drive of the "heart" of the shield machine.
Designing the "heart" of a "behemoth" with nearly 30,000 parts and components covering more than 10 disciplines and technologies is a huge challenge for Meng Xiaoning, who has just graduated.
There is no technical reference, so she designs while exploring, and keeps an eye on the site during the day to measure and set parameters;In the evening, check Chinese and foreign materials to optimize the design plan. After nearly four months of research, she led the team to finally gnaw the "hard bone" of main drive research and development. Half a year later, Jinan Heavy Industry's first shield machine with independent intellectual property rights was successfully rolled off the assembly line.
In 2020, in order to further realize the transformation from the industry's "companion" to "leader", Jinan Heavy Industry decided to develop a 15-meter ultra-large diameter shield machine. The main drive of the super large shield adds telescopic and swing functions, and the development difficulty is far greater than that of the conventional shield machine. In order to overcome the difficulties, Meng Xiaoning braved the high temperature and scorching heat to go to the construction site of the Yellow Tunnel on Jiluo Road many times to observe and learn, and constantly promote the upgrading of R&D technology. After nearly half a year of research, she once again successfully overcame the challenge and improved the company's shield R&D capability from 6 meters to 15 meters, achieving a qualitative leap in technology.
Deeply cultivating the field of shield machine research and development, Meng Xiaoning continues to study new situations, solve new problems, promote new practices, and create a new situation, and has successively obtained 3 scientific and technological achievements, published 7 articles, authorized 7 patents, and led the research and development of shield and pipe jacking products, and has successively won the first prize of "Shandong Machinery Industry Science and Technology Award", "the first set of products in Shandong Province", "2022 Shandong Province Intelligent Intelligent Manufacturing (Industry 4.).0) First Prize of Innovation and Entrepreneurship Competition" and other honors.
