Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of blasting vibration monitoring, and specifically relates to an angle-adjustable vibration sensor installation protection device. BACKGROUND

[0002] As an important means of mature technology, blasting excavation has been widely used in mining, construction and water conservancy engineering industries. Blasting excavation technology not only significantly improves construction efficiency and reduces engineering cost, but also is a high-risk engineering activity involving a large amount of explosive materials and complex geological environment. Therefore, it is necessary to conduct safety monitoring during the operation. Blasting vibration monitoring is of great significance: ensuring personnel safety, preventing structural damage and protecting the natural environment.

[0003] The existing blasting vibration monitoring generally sets up multiple monitoring points within a certain range of blasting operation, uses vibration sensors to collect the vibration information of the vertical, horizontal radial and horizontal tangential points, and compares and analyzes it with the relevant standards and specifications. The vibration sensor should be always horizontal during operation, and the X direction should point to the seismic source. In engineering practice, due to the restriction of topography or structure, the monitoring points are often undulating or even located on an inclined surface. Therefore, it is necessary to use shims, concrete or other materials at the bottom of the vibration sensor to create a flat mounting surface. Although this method can basically meet the installation requirements of the vibration sensor, it has the disadvantages of high installation requirements, difficult post-maintenance and inability to provide all-around protection for the sensor.
