Problems solved by technology

[0002] From the sense of the word, the road is the infrastructure for all kinds of trackless vehicles and pedestrians; Forestry roads, examination roads, competition roads, automobile test roads, workshop passages and school roads, etc. There were also post roads in ancient China. Today's road construction is mostly paved with concrete or asphalt to enhance the load-bearing strength of the road and avoid it. It is used for vehicles, and the preparation of concrete or asphalt is a relatively complicated process. Regardless of the ratio of raw materials, the subsequent mixing and even the solidification process, it will have a great impact on the strength of the prepared concrete or asphalt. Therefore, in road paving After the completion, it is necessary to grind and sample the surface of the pavement to test the strength of road materials, so as to ensure the load-bearing strength of the road. Most of the existing detection methods are to manually knock the pavement to obtain samples and then test them. Although this method is simple Convenience, but because it is difficult to control the strength, it is easy to produce depressions at the knocking position, affecting the appearance of the road surface, and it will also cause wear and tear on the vehicle tires when the vehicle passes through the depressions, causing safety hazards for the vehicle. In addition, when excavating the road surface and sampling It is also necessary to consider whether there are pipelines buried under the ground, and it is necessary to use external equipment to detect underground sensitive objects in advance, so it is also necessary to configure external detection equipment. In addition, during the road sampling process, there is a defect that the excavation block heats up, which leads to a decrease in the efficiency of excavation and sampling , in view of this, we propose a road bridge strength detection device
