Description

Technical Field

[0001] The utility model relates to a surrounding rock loosening circle snooping device based on short-distance wireless communication, belonging to the technical field of surrounding rock loosening circle testing in geotechnical engineering. Background Art

[0002] Accurate and timely grasp of the surrounding rock type and physical and mechanical properties is one of the main ways to reduce engineering accidents. The surrounding rock loosening zone has a great influence on the stability of underground projects and is an important indicator for the reasonable evaluation of geological conditions such as the ground stress of the tunnel surrounding rock. In general, the larger the range of the tunnel surrounding rock loosening zone, the more difficult the tunnel support is. When the surrounding rock conditions remain unchanged, the greater the surrounding rock stress, the larger the loosening zone range. In order to reasonably optimize the tunnel support parameters, reduce the deformation of the tunnel surrounding rock, and ensure the safe and normal production of the tunnel, the surrounding rock loosening zone range test is carried out to grasp the damage range of the tunnel surrounding rock and solve the problem of large deformation of the tunnel surrounding rock.

[0003] At present, the borehole peeping method is one of the most commonly used test methods in the test of the loose circle of the surrounding rock. The traditional borehole peeping method has the following limitations: 1. The traditional peeping method requires workers to use a multi-section push rod to push the peeping device into the borehole for peeping. It usually takes 30 minutes to peeping a 10-meter borehole, which is inefficient and labor-intensive; 2. The traditional peeping method uses a cable connected to the rear of the peeping device, and the cable is wound around the distance counter roller to count the advancement distance. Due to the friction between the cable and the borehole wall and the roller, it is time-consuming and labor-intensive to manually drag the push rod to push the peeping device. When encountering foreign objects stuck in the main cable, it is easy to damage the cable; 3. In the traditional peeping method, workers use a multi-section push rod to push the peeping device for peeping. It is difficult for workers to keep the peeping device balanced and stable for a long time. The peeping device is easy to shake, and the peeping imaging is difficult to achieve complete and stable image splicing. 4. In a soft rock and water-rich environment, the surrounding rock is easy to become muddy. The traditional peeping device peeping lens is very easy to stick to mud debris. When the mud debris sticks to the lens, the accuracy of the peeping is affected. In addition, the drilling hole is easy to collapse in a soft rock environment. When the hole collapse is serious, multiple drillings are required, which seriously affects the test efficiency and wastes manpower and material resources. For this reason, the utility model is proposed. Summary of the invention
