Ultrahigh-strength broken bullet protective layer

Abstract

The invention discloses an ultrahigh-strength shattering and bullet protecting layer which sequentially comprises an ultrahigh-strength steel layer (1), a common steel layer (2) and a concrete layer (3) from top to bottom, all the layers are detachably and fixedly connected into an integral composite structure through ultrahigh-strength device assembly connecting pieces, and meanwhile disassembly and replacement are convenient. The ultrahigh-strength alloy steel which is high in strength, good in fracture toughness, high in impact load resistance and low in cost is adopted as a first-layer material; different safety levels can be achieved by adopting different thickness matching schemes for all the layers, and typical earth-penetrating bullets with different equivalent weights, especially earth-penetrating weapons with large equivalent depths, can be impacted and broken. According to the composite structure, an ultrahigh-strength material is adopted, so that the earth-penetrating bomb is impacted and broken, and the protection capacity is improved; meanwhile, the structure is simple, manufacturing is easy, the application range is wide, and prefabricated components are convenient to construct, and can be applied to bullet shielding layers of military engineering and civil air defense engineering.

Description

technical field [0001] The invention relates to the technical field of safety protection engineering, in particular to an ultra-high-strength fragmentation protection layer. Background technique [0002] Protective engineering has important strategic value in both military and civilian fields. At the military level, weapons with improved ground-penetrating performance continue to pose an ever-increasing threat to military protection projects, and in global hotspots, peacekeeping stations are close to combat zones, and most peacekeepers and site environments do not have the necessary construction conditions and equipment for large-scale protection. Therefore, The need for new protective structures is very urgent. At the civilian level, infrastructure such as civil air defense projects and nuclear power plant reactors requires qualified and effective protective materials and equipment to ensure the orderly progress of normal production and life in the civilian field and to sa...

Problems solved by technology

Under the existing technology, construction conditions and test conditions, there are certain difficulties in the engineering use of the protective layer structure with good performance. For example, the high-content steel fiber concrete with good anti-penetration performance in the test is difficult under the current construction conditions. Large-area pouring is not suitable for on-site use; the large-scale use of materials has a great impact on the structure, which seriously restricts engineering design and construction
