Foam lightweight concrete railroad bed structure
The invention relates to a foam lightweight concrete railroad bed structure. According to the railroad bed structure, an upper railroad bed and a bottom railroad bed are formed by pouring foam lightweight concrete. The upper railroad bed is formed by pouring the foam lightweight concrete with the wet density of 550-600 kg/m<3>, and the bottom railroad bed is formed by pouring the foam lightweight concrete with the wet density of 500-550 kg/m<3>. The railroad bed structure is formed by integrally pouring and constructing the foam lightweight concrete, and compared with the common railroad bed padding construction period, the railroad bed padding construction period is shorter. The railroad bed can bring the performance of the materials into full play through the load function of a train, good using performance is kept, the running stability and comfort of the train can be guaranteed, the disease of the railroad bed is reduced, the maintaining cost in the operation period is saved, and the foam lightweight concrete railroad bed structure is very suitable for high speed railroad beds.
