Abstract | The invention relates to a high polymer gravel protection device for eliminating underwater near-field blasting shock waves. The device comprises a high polymer, wire meshes, gravel and steel plates, the gravel is filled between the wire meshes to form a protection body, then the high polymer is poured to form a protection mechanism, the steel plates are pre-buried on both sides of the protection mechanism, lifting lugs are formed at the two ends of the steel plate extending out of the protection mechanism, and lifting holes are formed in the lifting lugs. The sudden change of wave impedance between a high polymer gravel protection mechanism and a surrounding water medium and sealed bubble diffuse reflection shock waves on the irregular surface of the gravel and in a high polymer material are utilized, the shock wave impulse and total energy are well weakened, the gravel is fixed through the wire meshes, the plastic deformation capacity of the protection mechanism is improved, the protection mechanism is not |
