The invention discloses a local strengthening method for road subgrade, which comprises the steps of S1, subgrade detection and S2, subgrade compaction. In the compaction process, when it is detected that the subgrade is void or the compaction degree and the thickness do not meet the requirements, a shell is pushed, a first bevel gear and a second bevel gear are driven to rotate by rotation, meanwhile, a third bevel gear and a fourth bevel gear are driven to rotate by a transmission rod, when the third bevel gear rotates, a first cam and a second cam are driven to rotate by a coupler, a crankshaft further rotates along with the first cam and the second cam, the crankshaft drives a pressing rod and a pressing block to perform circulating reciprocating motion, and a subgrade is compacted by means of the gravity of a pressing head and the pressure of the pressing rod; meanwhile, in combination with a ground penetrating radar technology, a level map of electromagnetic wave echoes is acquired, and in combination with an edge detection technology, then edge conversion is performed according to the level map to accurately obtain the thickness, the compaction condition and the void condition of a subgrade structure layer, so that the detection efficiency is improved, the pavement is not damaged, the pavement is comprehensively detected, and problems can be timely found and treated.
本发明公开了S1，路基检测，S2，路基压实，在进行压实的过程中，对于检测出路基有脱空或者压实度、厚度不满足要求的情况，推动壳体，通过转动的转动，带动第一斜齿轮和第二斜齿轮转动，同时通过传动杆带动第三斜齿轮和第四斜齿轮转动，第三斜齿轮在转动时，通过联轴器带动第一凸轮和第二凸轮转动，进一步曲轴跟着发生转动，曲轴带动压杆和压块做循环往复运动，依靠压头的重力和压杆的压力对路基进行压实；同时结合探地雷达技术获取电磁波回波的电平图，并且结合边缘检测技术，之后根据电平图进行边缘转换精确得出路基结构层的厚度、压实情况和脱空情况，提高检测效率，不损伤路面，对路面进行全面检测，有助于及时发现问题、治理问题。
