[0002] Explosive ultra-high pressure bimetallic welding composite is usually done by loosening the soil, then laying a base plate on the soil, laying steel balls on the upper side of the base plate, and then laying a composite plate. Explosives are laid on the upper side of the composite plate, and a detonator is set at one end of the explosives. The explosives are ignited by the detonator.

The outer shell 3 and the inner shell 24 are both cylindrical bodies with open ends. The front end of the outer shell 3 is provided with a vertical plate 1, which closes the front end of the outer shell 3. The middle part of the vertical plate 1 is provided with a wave breaker port 7. The rear end of the vertical plate 1 is provided with a sealing plate 5, which is fixedly connected to the outer shell 3 and closes the rear end of the outer shell 3. The middle part of the sealing plate 5 is convex. The sealing plate 5 is a porous plate, and a cloth bag 26 is connected to the side of the sealing plate 5 away from the outer shell 3. The inner shell 24 is arranged in the outer shell 3, and an air flow channel is provided between the outer shell 3 and the inner shell 24. The two ends of the outer shell 24 are fixedly connected to the vertical plate 1 and the sealing plate 5 respectively. The conical covers 2 are disposed within the inner shell 24. The dimensions of the conical covers 2 gradually increase along the direction of the shock wave, i.e., the dimensions of the conical covers 2 gradually increase from the head end to the tail end, forming a flared shape. The small end of each conical cover 2 is provided with a conical opening 6, and the large end of the inner cavity of each conical cover 2 is provided with a rounded corner 25.
