Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a roadbed compacting device. Background Art

[0002] The roadbed is the foundation of the track or road surface. It is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transferring and diffusing the load deep into the foundation. In the longitudinal section, the roadbed must ensure the required elevation of the line. In the plane, the roadbed is connected with bridges and tunnels to form a complete through line. The existing roadbed needs to be compacted by rolling, tamping or vibration.

[0003] The document with prior art publication number CN211848753U provides a roadbed construction compaction device. The device cooperates with the spring, limit plate, hemisphere, swing plate and rotating ring and the convex column. The rotation of the arc plate drives the corresponding swing plate to swing, so that the swing plate contacts the hemisphere, thereby driving the slide rod to rise and fall, and then repeatedly driving the compaction plate to compact the ground, thereby improving the compaction effect.

[0004] However, during the process of roadbed filling, the roadbed filler is prone to agglomeration if it encounters low temperature weather. Direct compaction cannot destroy the agglomerated or blocky fillers in the roadbed, and they can only remain in the roadbed, destroying the stability of the roadbed structure. In view of this, we propose a roadbed compaction device. Utility Model Content
