Description
Technical Field
The invention belongs to the technical field of rock engineering, and relates to a simple sensor assembling and disassembling support and a using method thereof.
Background
Dynamic disasters such as slope landslide, rock burst, water burst, coal mine gas and the like are frequently encountered in rock engineering, so that safety of constructors and equipment is seriously affected, and construction progress is greatly hindered. Therefore, it is necessary to take real-time dynamic disaster warning measures. The micro-seismic monitoring technology is widely applied as a novel rock fracture monitoring tool, is implemented in hydropower station side slopes, tunnels, coal mines and other heavy projects at present, and obviously restrains dynamic disasters such as rock burst, water inrush, gas and the like.
For rock slope stability monitoring, microseismic sensors are deployed in the borehole once and remain permanently monitored. However, for long tunnels in underground engineering and engineering in which the construction working face is continuously linearly forward along with the construction progress, the microseismic monitoring sensor needs to be continuously adjusted according to the construction progress. Moreover, the construction environment of underground engineering is complex, and reinforcement measures such as concrete spraying and the like are often required. Therefore, the microseismic sensor in the engineering needs a simple installation and disassembly device, and simultaneously, the characteristics of low cost, obvious effect and the like of the device need to be considered.
