[0001] The invention relates to an anti-overturning explosion-proof unit and a quick-assembly explosion-proof wall, belonging to the technical field of explosion-proofing. Background Art

[0002] In order to respond to attacks and improve the protection against lethal weapons and ammunition, quick-assembly explosion-proof walls have been widely used. The explosion-proof walls can effectively protect against various types of light weapons, reduce the damage caused by explosion shock waves, and reduce the lethality of fragments.

[0003] The limitations of the existing technical status are: 1. The construction of explosion-proof walls is not very convenient, requiring more personnel and equipment; and the construction speed is slow, which is difficult to adapt to the ever-changing needs of the battlefield. 2. Explosion-proof walls mainly made of steel plates and concrete are not convenient to recycle, and the cost is high, making it difficult to invest on a large scale. 3. The explosion-proof wall has weak anti-overturning ability and is prone to collapse when encountering explosion shock wave loads or penetration. 4. If the old-fashioned quick-assembly explosion-proof wall wants to increase the protection height, it is necessary to stack a second layer on the filled explosion-proof wall, but in actual situations, the second layer of the explosion-proof wall is relatively unstable and prone to collapse. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an anti-overturning explosion-proof unit and a quick-assembly explosion-proof wall.
