Geological radar slope retractable platform for quality inspection of concrete face dam and its working method

Abstract

The geological radar slope retractable platform and its working method for the quality inspection of concrete face dams. The retractable platform is provided with a truss, and the geological radar is fixedly connected to the truss. The feature is that the truss is fixedly connected with the lifting mechanism, and the lifting mechanism is connected with the control mechanism. The control mechanism controls its lifting; the bottom end of the lifting mechanism is provided with a scroll wheel. A camera system is installed on the truss of the optimization scheme. The invention can prevent the radar from overturning, and improves the safety and stability of detection; it can avoid jamming and encountering obstacles, and the movement is smooth; when the radar antenna is recovered after the measurement, it can be separated from the concrete panel. The invention avoids the influence of the antenna base plate on the detection result due to wear and tear, saves costs, and greatly reduces the physical burden and work risk of the detection personnel; the system can save labor for 2-3 people; the adoption of the high-definition camera system can Monitor the detection line and play back.

Description

technical field [0001] The invention relates to a geological radar slope retractable platform for quality inspection of concrete face dams. The invention also relates to the working method of the geological radar slope retractable platform for the quality inspection of the concrete face dam. Background technique [0002] Due to the advantages of good safety, convenient construction, short construction period and low cost, concrete face dams have been greatly developed in recent years. But so far, due to various reasons, the incompatibility between the face plate and the cushion layer cannot be completely controlled, which leads to the void phenomenon, which is especially obvious in the early face face dams. At present, the most direct and effective methods for the detection of voids in concrete panels are hole drilling and sampling tests. However, due to the limited number of hole drilling, the blindness, and the damage to the panel itself, there is an urgent need for novel...

Problems solved by technology

In this way, it not only delays the time, but also affects the continuity of the detection and the accuracy of the position. The friction and collision between the bottom plate and the concrete panel, on the one hand, will cause the wear and deformation of the bottom plate, which will directly affect the arrival time of the first wave of the antenna during measurement, and affect the reliability of the test results. The resulting physical burden is also significantly increased; in addition, due to the steep slope of the panel, personnel cannot walk with the antenna during the detection process, and the detection line is long, and the "road conditions" far away from the detection line cannot be observed. It directly affects the judgment of data analysts, which in turn affects the quality of data analysis
