Recently, the "Cave Detection Device for Underground Construction" declared by the company has been granted a national invention patent by China National Intellectual Property Administration.

This innovative device features an annular array of at least three drilling units mounted on a cylindrical casing, enabling coordinated operations that significantly expand detection coverage and efficiency while providing comprehensive cave morphology mapping. The patent also introduces a retractable protective cover for sonar probes, which remains folded during drilling to prevent debris collisions with borehole walls, automatically deploying only when safely entering caves to ensure uninterrupted operations and minimize equipment damage. By integrating detection with preliminary sampling, the system enhances data acquisition capabilities and provides critical geological analysis support. Its modular drilling unit allows rapid replacement through threaded connections, greatly improving adaptability to diverse exploration needs and geological conditions.

This breakthrough technology delivers precise cave distribution data for construction projects, effectively preventing risks like cave collapses and water surges at source, thereby substantially elevating safety standards in underground engineering. At the same time, it reduces the dependence on a large number of boreholes in the construction process of the project, improves the detection efficiency and the overall economy of the detection work, further provides a new direction for technological progress in the field of geological exploration, provides key technical support for the safe and efficient development and utilization of underground space, and effectively alleviates the shortage of ground space resources.
