No water coupling, suitable for drilling in any direction, especially suitable for detection and forecasting of the loose area of ​​rock mass around the tunnel; long detection distance, detection distance up to 50 meters in concrete; no high voltage power supply required; CT imaging. Achievements and technical characteristics Product overview Sichuan Shengtuo Testing Technology Co., Ltd. provides a cross-hole type rock mass mechanical property tester. The instrument is mainly used for testing the internal mechanical characteristics, defects, joints, etc. of large-volume concrete and rock masses. The test uses waterless vibration and coupling technology, which can be applied to various directions such as oblique holes and upward holes. Any dry hole with a diameter between 90mm and 110mm can be tested. The maximum test distance can reach 50m. At the same time, it has rich post-graphics processing functions: such as elastic wave radar EWR, computer tomography CT, 3D slicing technology and automatic fast processing skills, etc., which can bring the most concise and intuitive detection results. Long test distance, up to 50m. Water-free coupling technology, suitable for horizontal, upward and cracked drilling. Test object: large concrete structure, natural rock mass structure, etc. Test content: mass concrete for tunnels, dams, etc. Internal mechanical characteristics, defects, and joints of rock masses When testing large-scale concrete structures, cross-hole devices can be used to test the concrete structure characteristics and defects between drilling holes (the cross-hole device uses waterless coupling and excitation technology, which is applicable Drilling holes in various directions, the maximum test distance can reach 50m), using automatic excitation device and cylinder pressure sensor fixed method, strong directivity, low attenuation. Test principle and method of cross-hole type rock mass mechanical property tester SRE-CMT
