TJGZ- Expansion joint is primarily divided into the types of JC, AW and TW. The JC waterproof/draining expansion joint for ballastless track is suitable for the applying to the bridge with the expansion joint free from any vertical load. The expansion joint is characterized by low cost, good waterproofing and drainage performance, easy repair and replacement, etc. The AW waterproof/draining expansion joint for ballastless track is suitable for the bridge with the expansion joint free from any vertical load. The primary material of the AW expansion joint is rubber. In order to increase the stiffness of the rubber, an anchorage is added on two sides of the expansion joint. The AW expansion joint is mainly used for the bridge or building with great requirements on the replacement and, damping and energy dissipation. It is featured by large displacement and rotation angle, energy dissipation through friction, easy repair and replacement. The TW waterproof/draining expansion joint for ballast track is suitable for applying to the bridge with the expansion joint bearing the vertical load. The primary material of the TW expansion joint is rubber. In order to increase the stiffness of the rubber, a fixed block is added on two sides of the expansion joint.
Haikou Viaduct of Hainan East Loop Line, Italian High-speed Railway, Mozambique highway, Guiyang-Guangzhou railway
Guiyang-Guangzhou Railway is a key project of "the Eleventh Five-Year Plan". The total length is 857km and there are 21 stations along. It is a double-line electrified railway and there will be 100 pairs of trains each day. The designed construction period lasts for six years. It is estimated total investment is 85.8 billion yuan. This project uses the expansion joint.
Hainan Eastern Loop
Hainan Eastern Loop has been invested more than 16 billion RMB, which is the biggest infrastructure construction project in Hainan province at present.
This line is an inner-city public passenger-dedicated line which is fast, safe and comfortable. It is electric traction, pollution-free, and the rail adopts our expansion joint to connect which has no gaps. It will give comfortable environment for everyone.
