Technical Field

The invention relates to a seismic wave method tunnel advanced geological prediction explosive package installation device, and belongs to the technical field of seismic wave method tunnel advanced geological prediction.

Background

In the existing seismic wave method tunnel advanced geological forecast, the depth of a blast hole is generally taken as the position of an explosion point for data processing, the measurement of the explosion point and the installation of an explosive package generally comprise the steps of firstly measuring the depth of the blast hole by using a plastic pipe with scales, and then plugging the plastic pipe for the explosive package bound with a detonator and an explosive into the blast hole, and the working mode has the following defects:

if rock debris exists in the blast hole or the blast hole collapses after the depth measurement is finished, the explosive package cannot be placed at the bottom of the blast hole, the explosive package not placed at the bottom of the blast hole can cause inaccurate measurement data due to the fact that an actual explosion point is inconsistent with a measured explosion point, accuracy of a forecast result is influenced, and explosion sound is too loud due to too shallow depth of the explosive, so that the environment is influenced;

if rock debris exists in the blast hole or the blast hole collapses after the depth measurement is finished, the explosive and the detonator are easily separated in the explosive filling process, the explosive separation of the detonator can not only cause the explosive to be incapable of being detonated and the seismic source to be invalid, but also cause potential safety hazards due to the fact that the explosive cannot be taken out;

the explosive package is directly plugged into the blast hole by using the plastic pipe, and in the process of withdrawing the plastic pipe, the detonator and the explosive are easily separated or the explosive package filled into the bottom of the blast hole is taken away from the bottom of the blast hole due to the friction between the plastic pipe and a detonator pipeline, so that the explosive can not be detonated or the actual explosion point is inconsistent with the measured explosion point;

the seismic reflection wave method is used for advanced geological prediction, and water is needed to be used as a coupling agent of an explosive package and surrounding rock to improve the geometric coupling relation between explosive and the surrounding rock, improve the utilization rate and the action capacity of explosion energy and increase the penetrating capacity of seismic waves in a rock stratum. The existing irrigation mode is that a plastic hose extends into a blast hole by 20-30 cm, water is irrigated into the plastic hose from an orifice, and water flows into the bottom of the hole.
