Abstract

The invention discloses a wireless-distributed-type elastic wave reflector detection device, system and method. The device comprises a control terminal, a wireless data storage device, vibration signal receiving devices, a wireless data acquisition device and a vibration excitation device. A wireless three-dimensional space distributed-type elastic wave acquisition instrument, a wireless data storage instrument and a manpower small-energy hammering method are adopted so that a large number of elastic wave signals can be rapidly, conveniently and safely acquired. The eleven vibration signal receiving devices distributed in a three-dimensional space mode are used for acquiring thorough and complete three-dimensional space elastic wave field data with enough density, and therefore an accurate and high-precision geological three-dimensional image is obtained through analytical calculation. The wireless-distributed-type elastic wave reflector tracing analysis detection device has the advantages of being extremely high in signal-to-noise ratio, concise in structure, low in weight, low in energy consumption, safe in use, easy and convenient to install, high in measurement efficiency, high in detection precision, high in accuracy, large in detection range and the like.

Description

technical field

[0001] The invention belongs to the technical field of engineering geophysical prospecting, and can be used for tunnel geological advance forecast detection, deep-buried pile foundation detection, mine prospecting and other geological detection, and specifically relates to a wireless distributed elastic wave reflector detection device, system and method. Background technique

[0002] At present, the application of seismic wave method for geological advance prediction, pile foundation detection, prospecting and other geological detection is one of the most commonly used, most effective and fastest methods. The working principle of the seismic wave method is to excite elastic waves in an arrangement in the surrounding rock of the tunnel. When the elastic waves propagate to the three-dimensional space, they encounter the acoustic impedance interface, that is, the interface of geological and lithological changes, structural fracture zones, karst and karst developm...
