Description

Technical Field

[0001] The utility model belongs to the technical field of earthquake detection, and particularly relates to an installation device for an advanced geological prediction detector. Background Art

[0002] During the tunnel construction process, adverse geological phenomena such as faults and broken zones are often encountered. It is necessary to find out in advance whether there are adverse geological bodies in front of the tunnel face to avoid safety hazards. Therefore, it is of great significance to find out the adverse geological bodies in front of the tunnel face in advance, realize the understanding of the geological structure and the state of the ore layer in front, and take preventive measures in advance to ensure the safety of tunnel construction. The seismic advance detection method uses the reflection, diffraction, scattering and other characteristics generated when seismic waves propagate in uneven geological bodies to predict the geological conditions in front of the tunnel excavation and the surrounding adjacent areas. There are mainly reflection wave method and Rayleigh wave method. In order to facilitate detection, it is usually necessary to install the detector in a pre-prepared borehole. In the prior art, when installing the detector, the detector installation device usually uses a push mechanism to push out the detector stuck in the installation device. This push-out structure will cause the detector to rotate and deviate when it is pushed out, so that it cannot be correctly installed in the borehole. In addition, when the detector is pushed by the push mechanism, it may also cause the detector to be damaged due to excessive force. For example, patent CN220436142U discloses a TST advanced geological prediction detector and gun mud installation device, which uses a push rod assembly to push the detector stuck in the delivery rod assembly into the borehole. Since the detector is pushed forward, the detector may rotate and become skewed after being pushed, which may cause the detector to be installed improperly and the detector may be damaged when being pushed.
