Clinometer for high-precision radial drill holes inside rock-plug blasting cave

The utility model relates to a clinometer for high-precision radial drill holes inside a rock-plug blasting cave, and belongs to the field of exploration and construction of water conservancy and hydropower geotechnical engineering. A sighting table is fixedly connected with a guide pipe, a light transmitting round measurement board is connected to the pipe mouth of the guide pipe in a clamped mode, a water outlet is formed below the pipe mouth of the guide pipe, a measurement rod is located in the guide pipe, the front end of the measurement rod is fixedly connected with a light source, and the rear end of the measurement rod is connected with the light transmitting round measurement board in a penetrating mode. The clinometer for the high-precision radial drill holes inside the rock-plug blasting cave has the advantages that the structure is novel, the degree of skewness of the radial holes is measured through the clinometer, the measurement precision can reach 0.5/1000, the safety and applicability are ach
