Abstract
The invention relates to the technical field of engineering investigation and exploration, and specifically relates to an umbrella-type deep hole three-dimensional stress and displacement comprehensive testing device. The umbrella-type deep hole three-dimensional stress and displacement comprehensive testing device comprises an umbrella-type testing mechanism, a displacement sensor, a manual pressure pump, a test guide rod and a signal acquisition instrument. The comprehensive testing device can test the three-dimensional stress of multiple positions at different depths in a deep hole and test point stress variation conditions and displacement conditions influenced by human engineering, thereby providing an important basis for rock mass engineering construction, roadway and chamber maintenance and the like. The comprehensive testing device provided by the invention effectively solves problems that traditional stress measurement and displacement measurement are mutually independent, difficult to perform multi-point implementation in the same drill hole, time and labor consuming, high in cost and the like. The comprehensive testing device not only realizes one-hole-multiple-point three-dimensional stress and displacement measurement, but also can perform continuous measurement, thereby realizing a dynamic evaluation function. In addition, the comprehensive testing device has the characteristics of ability of being recoverable, repeated utilization and the like, and has the advantages of low test cost, convenient carrying, simple and convenient field operation, automatic data acquisition and the like.
Description
technical field [0001] The invention relates to the technical field of engineering survey and survey, in particular to an umbrella-shaped deep hole three-dimensional stress and displacement comprehensive testing device. Background technique [0002] In rock and soil engineering such as underground mining of mineral resources, water conservancy and hydropower, road tunnels, and foundations, the timely monitoring and analysis of stress and surrounding rock displacement is an effective method to prevent large deformation and damage of the surrounding rock of the project and implement safe and efficient production. This is because the underground mining of mines and other rock mass engineering constructions will cause the original rock stress field to change and form a new stress state, resulting in an affected area and stratum displacement in a certain range of surrounding rock bodies. If the rock displacement cannot be controlled effectively in time, it will lead to engineerin...
