The invention discloses an automatic measuring and alarming instrument for tunnel vault crown settlement and a usage method. The automatic measuring and alarming instrument for tunnel vault crown settlement comprises an anchorage probe which is connected with a comprehensive displacement meter through a connecting rod line, the connecting rod line penetrates through a supporting plate which is fixedly connected with an instrument protection casing pipe, the comprehensive displacement meter is fixed in the instrument protection casing pipe and penetrates through a fastening support plate to be connected with a data processing and alarming system through a connecting component, the data processing and alarming system is provided with a liquid crystal display screen, a switch key, a zero setting key, a setting key and a measuring key, and a public address device for sending an alarming signal is arranged on the lower portion of the data processing and alarming system. The instrument can be used for real-time measurement of tunnel vault crown settlement of a shallow-embedded tunnel section, tunnel entrance and exit sections and a broken tunnel surrounding rock section and quickly pre-alarm a dangerous situation in time to avoid personal casualty.
Description
technical field [0001] The invention relates to the technical field of tunnel on-site measurement, in particular to an on-site automatic measurement and alarm instrument for tunnel vault settlement and a use method. Background technique [0002] In the process of railway and highway construction in our country, the proportion of tunnels is getting heavier and heavier. In the tunnel construction project, vault cracking and subsidence or even landslide accidents are very likely to occur in the shallow buried section of the tunnel entrance or in the broken surrounding rock zone, especially in the shallow buried section with broken surrounding rock, where the risk of accidents is extremely high. At present, the measurement of tunnel vault settlement mainly relies on monitoring personnel and monitoring instruments. The frequency of measurement varies, and it is impossible to continuously monitor the changes of dangerous tunnel vault settlement in real time, and cannot quickly and...
