Abstract

The invention discloses a vibration monitor applied to the depth direction and a monitoring method. The monitor comprises a vibration isolation pile casing, an upper circular fixing plate, a lower circular fixing plate and a vibration detection platform; a vibration detection module is arranged at the bottom of the vibration detection platform; a lifting mechanism is arranged between the upper circular fixing plate and the lower circular fixing plate; a horizontal adjusting mechanism is arranged between the lower circular fixing plate and the vibration detection platform; and a camera is arranged in the center of the bottom face of the upper circular fixing plate. The method comprises the following steps: 1, arranging monitoring holes; 2, assembling a vibration monitor; 3, mounting and adjusting the vibration monitor; and 4, acquiring and transmitting vibration data. The vibration monitor is reasonable in design and low in cost, a vibration pickup device can be conveniently installed in the vibration monitoring hole, it is guaranteed that the vibration pickup device is leveled, the vibration monitoring precision is improved, and the timeliness of monitoring data is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vibration monitoring, and in particular relates to a vibration monitoring instrument and a monitoring method applied in the depth direction. Background technique [0002] With the rapid development of the country's infrastructure, underpass projects are also common, and subway tunnel underpass railway station projects also have great technical problems. Due to the passing of the train above, the additional dynamic load is added to the tunnel passing under, which causes additional stress on the lining of the tunnel and affects the safety of the tunnel. How to judge the size and propagation depth of train dynamic load becomes a difficult problem. [0003] Most of the underground subway tunnels are buried shallowly, and on-site in-depth vibration monitoring requires drilling measurement holes in the railway station area. There are the following problems in the monitoring: (1) the installation problem of th...
