Rolling compaction device suitable for different fillers in railroad bed construction and method

Abstract

The invention discloses a rolling compaction device suitable for different fillers in railroad bed construction and a method, and belongs to the technical field of railroad bed construction. The rolling compaction device involves roadbed layers, movable supports are fixed above the roadbed layers, and the two movable supports are provided and arranged on the roadbed layers at two ends of a road requiring the fillers correspondingly. According to the rolling compaction device suitable for the different fillers in railroad bed construction and the method, electric energy consumption is reduced,through meshing movement of gears at the two ends, the stability during movement is improved, the bearing performance of the device is improved, a motor rotates forwards and reversely to change the moving direction of the whole device, the device can be used for repeated material pressing, so that gaps between the fillers are dense, the compaction efficiency is improved, filler layers made of different materials are compacted more compactly by changing the vibration frequency according to the different fillers, road surface collapse in the later period is prevented, the road surface is repeatedly compacted, the flatness and compactness of the road surface are guaranteed, and aiming at the different fillers, the overall practical performance is improved by changing the weight of the interior of a compaction roller.

Description

technical field [0001] The invention relates to the technical field of railway roadbed construction, in particular to a rolling device and method suitable for different fillers in railway roadbed construction. Background technique [0002] Railway subgrade engineering is an important section of the national railway network. The construction site is located in a mountainous area, where not only the terrain is complex and dangerous, but also the traffic conditions are very poor. To carry out railway subgrade construction under such an environment, it is necessary to strictly control the quality of subgrade construction, so as to ensure the safety of railway transportation after the project is completed and put into use. Subgrade construction is directly related to the overall quality of the railway section. To ensure the construction quality and design requirements of the railway subgrade, during the construction of the railway subgrade, it is necessary to tamp the road surfa...

Problems solved by technology

Subgrade construction is directly related to the overall quality of the railway section. To ensure the construction quality and design requirements of the railway subgrade, during the construction of the railway subgrade, it is necessary to tamp the road surface through the road compacting device. The existing rolling device can only be used in multiple After the layers of fillers are filled, they are uniformly rolled, resulting in inaccurate gaps between fillers of different materials, which can easily lead to subsidence of the road surface, and cannot guarantee the quality of rolling
