Abstract

The invention discloses an explosion vibration sensor installation clamp applicable to soil mediums. The explosion vibration sensor installation clamp applicable to the soil mediums comprises an upper clamping plate (1) and a lower clamping plate (2). The both ends of the upper clamping plate (1) and the both ends of the lower clamping plate (2) are respectively provided with upper screw holes (3) and lower screw holes (4). The upper screw holes (3) are corresponding to the lower screw holes (4). The upper clamping plate (1) and the lower clamping plate (2) are provided with screw bolts (5). The upper ends of the screw bolts (5) pass through the upper screw holes (3) and the lower ends of the screw bolts pass through the corresponding lower screw holes (4). The both ends of the screw bolts (5) are connected to fixing screw nuts (6) in a screwed mode. The two sides of the lower clamping plate (2) are provided with fixing holes (7). The explosion vibration sensor installation clamp applicable to soil mediums of the invention is simple in structure and convenient to install. A sensor will not easily fall off in an explosion process, and effective data can be obtained. The explosion vibration sensor installation clamp applicable to the soil mediums has a relatively good adaptability, and fouling of the sensor will not occur; the cleaning is convenient; the installation speed is relatively fast and workloads of test personnel are reduced.

Description

technical field

[0001] The invention relates to the field of blasting test equipment processing and manufacturing, in particular to a blasting vibration sensor installation fixture. Background technique

[0002] In geotechnical engineering, blasting is a common cheap and quick way of excavation, but when rock mass is excavated by blasting, it will produce a lot of harmful effects, among which blasting seismic wave is one of them. The seismic waves produced by blasting will have an adverse effect on the stability of buildings (structures) around the explosion source. In order to solve this phenomenon, vibration testing methods are usually used to monitor the blasting seismic effects on the engineering site to determine the impact range of blasting seismic waves. and change blasting parameters. At present, the method of blasting vibration testing in the engineering field is as follows: select a certain number of measuring points at the test site, usually clean the surface cov...
