High-speed rail track slab breaks the German-Japanese technology monopoly
.
Recently, the production process of CRTSIII.
prestressed track slab assembly unit of high-speed railway jointly researched and designed by China Railway Corporation and Yinlong Co.
, Ltd.
passed the review
of an expert group in Hejian City, Hebei Province.
The expert group determined that its core technology, technology and equipment were the first in the world and had the international leading level
.
Track slab is an important component of high-speed rail track engineering and the key to ensuring the high-speed, safe and smooth operation of
trains.
In response to the national strategic needs, CRTSIII.
"Experimental Research on Ballastless Track Structure System of Pre-tensioned Prestressing System" was listed as a major research topic of the former Ministry of Railways in 2012, and was developed and produced
in the Hejian R&D Test Base of Yinlong Rail Company.
In 2013, the CRTSIII.
prestressed track slab with completely independent intellectual property rights was successfully
tested in the test section of Xi'an to Baoji passenger special line and Shenyang to Dandong.
This kind of track slab is suitable for high-speed railways of 300 km / h and above, and has been fully applied
in high-speed railways under construction and planning in Zhengxu, Beijing-Shenyang, Shanghehang, Beijing-Kowloon and other high-speed railways under construction and planning in the past two years.
According to reports, China's self-developed CRTSIII.
pretensioned prestressed track plate breaks the technological monopoly of Japan and Germany, compared with the original Japanese technology I type track plate and German technology type II track plate, overcomes its reinforcement system, prestressed two-way tension system, absolute design device, track plate connection system, anchor sealing system and other deficiencies, and is in a leading position
in the world.
The first generation CRTSIII.
prestressed high-speed rail track plate production line is cellar type, and the production process of the assembly unit that has just passed the review of the expert group belongs to the second generation production line, compared with the first generation of production line, it has the advantages
of steel mold flow cycle, uniform tensile force, accurate and efficient quality control, cost saving, and improving production capacity.
