Steel spring floating plate vibration damping ballast
Features: Multiple and complex processes, high construction precision requirements
Advantages: It has the ability to suppress and absorb noise, greatly reducing the noise and vibration when the rail train passes.
Laying process: steel cage track laying method
The Qingdao Metro Line 13 project first adopted the “steel cage track laying method” construction process in the underground section to lay the steel spring floating plate ballast.
The steel cage track laying method has increased the paving progress of the ballast from 25 meters per day of traditional manual paving to 50 meters per day, and the fastest can reach 75 meters. Because this process has the characteristics of mechanization and standardization, it can achieve precise control of the ballast accuracy.
Innovative laying of elevated U-beam integral ballast
In the track laying construction of the elevated U-beam integral ballast, the innovative use of the “track laying method” has overcome the construction difficulties such as narrow space on the bridge, slow progress of paving operations, low degree of mechanization, and great safety hazards, improving construction efficiency and saving labor costs. The innovative invention of the automatic sleeper separation platform ensures the accuracy of the sleeper spacing and improves the efficiency of rail assembly.
Introducing the high-speed rail CPIII track precision measurement system
The introduction and use of the high-speed rail CPIII track precision measurement system and the track fine-tuning trolley for linear and elevation adjustment ensures the stability of rail train operation and improves the comfort of passengers.
Improving the development of the rail material transfer trolley
Focusing on technical research and innovation, the “zero point” QC activity group was established, making full use of the upper flange plate of the U box beam, and developing the rail material transfer trolley, which improved the transfer and installation progress of the rails in the narrow space on the bridge and reduced labor costs.
