In the survey of highway bridges, due to limitations such as drilling machinery fragmentation and rock core recovery rate, drilling rock cores cannot reflect the actual geological conditions well, which brings great problems to construction, such as slope collapse, bridge pile foundation collapse, and so on. To improve the accuracy of drilling with existing technology, a significant increase in manpower and resources is required, as well as a considerable amount of time. If drilling is combined with in hole television measurement, the fragmentation of the formation can be intuitively determined, which not only ensures the construction period and cost, but also provides accurate geological data for designers. This article uses the method of borehole television measurement to accurately obtain the geological conditions of the site, which is worth learning from peers.
