by From March 23 to 25, after a three-day strict review, the prestressed concrete sleepers of the China Laos Railway Component Plant of China Railway 15th Bureau passed the CRCC certification of the China Railway Certification Center, marking that the China Laos Railway Component Plant has the supply qualification and has laid a solid foundation for achieving the track laying node construction period of China Laos Railway.
At the last meeting, the China Laos Railway Component Plant of China Railway 15th Bureau is located next to Highway 13, Huinamanyin Village, Nasitong County, the capital of Vientiane, Laos, covering an area of about 60 mu.
It undertook the task of providing materials for the new Boten Vientiane railway project of China Laos Railway (sleeper GZ01 and GZ02 packages, totaling 801257 Illa type, new III bridge, new II type sleepers, shuttle head sleepers, and 259 groups of P50 and P6012 # turnout sleepers).
Vientiane pillow making base will be built on October 8, 2019, and completed and put into operation on January 3, 2020.
In order to ensure that the CRCC certification of prestressed concrete sleepers can be successfully passed at one time, the project department has done enough homework in advance.
First, the project department successfully applied online at the China Railway Inspection and Certification Center after completing the application materials on January 14, 2020.
However, due to the impact of the domestic epidemic, the project department received the acceptance notice from the Certification Center on February 28; Second, the project department produced 4252 IIIqa bridge sleepers and 16 groups of CZ2209Z turnout sleepers that meet the base requirements of the certification rules from January 6, 2020 to March 21, 2020 as the review samples for this CRCC certification; Third, the testing, measuring and detection equipment has been calibrated according to the requirements; Fourth, held several meetings to deploy relevant evidence collection work, checked and improved the office work materials according to the chapters, articles and clauses in the detailed rules for evidence collection, and organized technicians to study the CRCC certification rules; Fifthly, the epidemic prevention measures shall be taken during the evidence collection period.
The experts shall live in the dormitory of the Project Department of the Vientiane Pillow Making Base, and shall be disinfected every day.
The mode of separate meals shall be adopted during the meal, so that the expert group can feel happy, comfortable and warm at home by carefully paying attention to every bit.
During the on-site inspection and certification of sleepers, the experts of the audit and certification team successively carried out strict inspection on the dimensions and appearance quality of the finished sleepers, carried out static load tests on the sampled sleepers, and strictly reviewed the on-site production equipment, raw material tests, office work data, personnel qualifications, training data, and various processes of sleeper production, all of which agreed that the data of sleepers met the specification requirements.
In particular, it is worth mentioning that this evidence collection work was carried out by the expert group at great risk when the global epidemic situation broke out and the prevention and control of various countries were upgraded.
After three days of intense work, the experts put forward valuable opinions on the production management of the project sleepers, which is also the process of improving the operation of the company’s quality management system, and also the process with the deepest benefits of the project.
The team’s rigorous, meticulous and impartial work style and rich professional theories were highly appreciated by the Project Department.
They are the most tenacious “strong wind and strong grass” on the China Laos Railway.
The medium and old component factory of China Railway 15th Bureau passed the CRCC certification of prestressed concrete sleepers at one time, which greatly encouraged the morale of all the construction personnel and created favorable conditions for the subsequent construction and production of the project.
The project will take the opportunity of passing the CRCC certification of sleepers to continue to work hard and strive for further achievements.
