Background
The history of the highway can be traced to the early stages of human society. In ancient times, people often built roads on rivers and coasts. The term highway originally originated in the roman empire period, when a series of stone roads for the army and trade were constructed. These roads are referred to as "Via highways" because "Via" is intended to be "road" in Latin.
In ancient China, road construction has also had a long history. As early as the week of commerce, china began the work of building railways, urban walls and palace. Over time, the construction of highways in China gradually progresses, becoming a nationwide traffic network.
The history of modern highways can be traced to the 19 th century, when there was an ever increasing demand for roads with long distance and high speed due to the development of agriculture and industry. At this time, new technologies and construction methods are beginning to be used, thereby accelerating the construction and development of highways.
Today, roads have become an integral part of the world's transportation system, which not only facilitates people's travel and trade activities, but also promotes economic development in various countries and regions.

In addition, the constructed highway also needs to be sampled, and the quality of the road pavement, the roadbed and the like can be known through the sample analysis by researching the sample, so that the quality control and the quality improvement are carried out. In particular, road sampling has several important roles: the road quality condition is monitored. By sampling and detecting the road surface, roadbed and the like, the physical, mechanical, chemical and other properties of the road surface, roadbed and the like, such as density, strength, thickness, water content and the like, can be known, so that the road quality can be evaluated. And optimizing the road design scheme. When the highway is designed, the construction schemes such as roadbed, pavement and the like can be optimized according to the sampling detection result, the consumption of materials is reduced, and the service life and the safety performance of the highway are improved. Eliminating quality problems. If the quality of materials such as highway pavement or roadbed is found to be problematic, the materials are repaired or replaced in time, so that the occurrence rate of highway accidents can be reduced, and the driving safety of the highway is ensured. In summary, highway sampling is an important highway quality control means, which can help highway construction and management departments to ensure highway quality and safety, and improve highway service life and benefit.
The existing highway construction rock drilling sampling device is huge in size and inconvenient to drill, and a sampling device with a small structure and convenient to drill needs to be designed.
