However, during the stacking process of the sandbags, the situation of uneven stacking or lateral position deviation of the sandbags may occur, resulting in local inclination and even the倾倒 of this sandbag wall. The sandbags in contact with the columns only achieve extrusion and fitting contact by their own weight. There is a lack of an explosion-proof structure that can quickly and standardly stack the sandbags, no related cooperation components that can actively connect with the columns, and no related treatment methods for timely and orderly standardizing the stacking positions of the sandbags.
