Road roadbed foundation bed long-term power stability evaluation system

Abstract

The invention discloses a road roadbed foundation bed long-term power stability evaluation system. A supersonic wave detection device is arranged on a right guardrail, a right side of the right guardrail is connected with a stability evaluation system display device, a left lower side and a right lower side of the right guardrail are provided with cable slots, a left lower side of a left guardrail is provided with a supporting rod, the supporting rod is provided with a high definition rotation data camera, the supporting rod is inserted into the road roadbed to realize fixed connection of the supporting rod and the road roadbed, the road roadbed comprises an asphalt concrete layer, a gravel road slag layer, a surface sand structure layer, a polyethylene soft plate layer and a bottom sand structure layer, a bottom portion of the asphalt concrete layer is provided with the gravel road slag layer, a bottom portion of the gravel road slag layer is connected with the surface sand structure layer, a bottom portion of the surface sand structure layer is provided with the polyethylene soft plate layer, and a bottom portion of the polyethylene soft plate layer is connected with the bottom sand structure layer. The system is advantaged in that the road roadbed is determined and evaluated through designing the stability evaluation system display device, intelligentization is realized, the structure is simple, and the system is simple for realization.

Description

technical field [0001] The invention relates to the technical field of civil engineering equipment, in particular to a long-term dynamic stability evaluation system for road subgrade beds. Background technique [0002] With the continuous development of social economy and the continuous construction of modern cities, large and small roads have been continuously built. The construction of roads has brought great convenience to people's travel. traffic pressure. However, because there is a certain slope between the slope and the ground, the soil on the slope will become loose after long-term sun and rain, which will cause landslides on the slope, and when the landslide occurs on the slope, the highway The subgrade will have subsidence, which will lead to cracks and sags on the road surface, which will damage the road and pose a great threat to the driving safety of vehicles. In view of the above problems, it is necessary to design a device for testing roadbeds, so how to des...
