9. The application method of the axial input-to-radial output explosion propagation structure is characterized by comprising the following steps of:
S1, penetrating the detonating cord (1) into lateral through holes (11) of the detonating tubes (2) so that each energy-collecting groove (8) is opposite to the upper end face of the explosive expanding agent (6) in the corresponding detonating tube (2);
S2, screwing the bolt body (7) through the bolt mounting hole (9), so that the anti-skid pressure head (10) compresses the shell (3) of the detonating cord (1) to fix the detonating tube (2) and the detonating cord (1);
s3, detonation is axially input from one end of the detonating cord (1) and is transmitted along the detonating agent (4) of the detonating cord (1);
s4, when detonation is transferred to any energy-gathering groove (8), the energy-gathering groove (8) gathers detonation energy, impact energy is formed in the radial direction of the detonating cord (1), and the detonation of the low-density explosive (6) on the upper layer in the corresponding detonating tube (2) is triggered;
S5, detonating the upper-layer explosive-expanding agent (6) after detonating, and detonating the lower-layer high-density explosive-expanding agent (6) to form amplified detonation energy and axially outputting the detonation energy along the detonation tube (2) so as to complete detonation transfer from single axial input to radial output;
And S6, detonation is continuously transmitted along the axial direction of the detonating cord (1), and the detonation of the explosive expansion drugs (6) corresponding to all the energy-collecting grooves (8) is sequentially triggered, so that one-path axial input is converted into multiple paths of radial output.
10. The axial input-to-radial output explosion propagation structure and the use method thereof according to claim 9 are characterized in that detonation output of each explosion expansion pipe (2) can be performed synchronously or sequentially, if the positions of the explosion expansion pipes (2) are required to be adjusted, the bolt body (7) is unscrewed, the explosion expansion pipes (2) are moved to the target positions, and then the bolt body (7) is screwed again to complete fixation.
