Description

technical field

[0001] The invention relates to auxiliary tooling for construction of a double-block ballastless track, in particular to a device for vibrating the concrete of the track bed slab around a double-block sleeper, in particular to a concrete vibrator around a double-block sleeper. Background technique

[0002] The Wuhan-Guangzhou Passenger Dedicated Line is my country's first high-speed railway with a design speed of 350Km / h. The design adopts the German Rheda2000 double-block ballastless track technology. The core of this technology is: using the tool rail to fix the prefabricated double-block sleeper; using the three-dimensional control measurement technology to accurately position the tool rail; the concrete of the cast-in-place track bed slab permanently fixes the double-block sleeper in the track bed slab; The long rails form a seamless line.

[0003] The double-block sleeper adopts steel mold prefabrication, steam curing process, and uses a release agent t...
