A clamping triaxial seepage and acoustic coupling rock tensile testing machine includes a sample and a scaffold-type tensile testing device. The scaffold-type tensile testing device has an upper chuck and a lower chuck. The upper chuck has an acoustic transmitting channel, one end of which communicating with the outside, and the other end of which having an acoustic transmitting probe. The lower chuck has an acoustic receiving channel, one end of which communicating with the outside, and the other end having acoustic receiving probe. An upper end face of the sample has with a seepage outflow hole while the upper chuck has a seepage outflow channel connected with the seepage outflow hole. A lower end face of the sample has a seepage inflow hole while the lower chuck has a seepage entry channel is connected with the seepage inflow hole.

Seepage and acoustic wave coupling system for rock tensile testing

The present invention describes a mechanical coupling microseismic monitoring system, which includes at least one microseismic sensor, push rods that are arranged at both ends of the microseismic sensor through a first connection mechanism to send the microseismic sensor into the monitoring hole, introduction mechanisms that are mounted on the push rods for introducing the microseismic sensor into the monitoring hole, and one microseismic monitoring computer that receives signals from the microseismic sensor; the microseismic sensor is a recoverable microseismic sensor; the first connection mechanism is a connection mechanism that can make the push rod swing relative to the microseismic sensor; the introduction mechanism is a three-roller introduction mechanism. The present invention meets the requirement of microseismic monitoring for different parts of deep monitoring hole using multiple microseismic sensors.

Monitoring system for deformations of gas storage

The present invention discloses an acoustic sensor for rock crack detection including an acoustic emission probe, a probe installation mechanism and a transmission mechanism which transmits a combination of the probe installation mechanism and the acoustic emission probe to a setting position inside a borehole in the monitored rock mass. The acoustic emission probe installation mechanism essentially includes a sleeve component, a guide component, an end cap and springs. The guide component is in pluggable connection with the sleeve component or the end cap. The assembled probe installation mechanism locks the acoustic emission probe in a probe sleeve of the sleeve component. The springs inside the elastic sleeve of the sleeve component are in a compressed state.
