Background
In the prior art, sand bags are mainly stacked layer by layer (several rows are built according to the severity of a flood situation) to resist the impact force of water. First, after the flood is flushed into the sandbag, water penetrates into the gaps of the sand, but under the complex factors of surface tension of the water and the like, the sand and the water are temporarily combined into a whole, and the whole sandbag is also heavy and can bear huge pressure of the flood. Secondly, once again when water enters the interstices of the sand, the whole sand becomes "stiff", also under the complex effects of surface tension, but at the same time becomes viscous and sufficiently soft. The wet sand can pile up a castle, and can also be molded into a required shape one by one, and the sandbags are nested with each other without a gap, so that flood is prevented from invading into the sandbag gap. These characteristics of sandbags determine their ability to act in "damming" and "blocking" floods. However, the sand bag walls which are piled up by personnel without training related skills are easily washed down by flood, and the flood prevention and flood fighting effects cannot be achieved. The flood prevention sand box for the hydraulic engineering is wide in application range of flood prevention occasions, and low-lying areas such as a subway entrance, a community, a garage entrance and the like need to be equipped in the flood season, so that the flood prevention sand box for the hydraulic engineering is convenient to assemble and combine and can resist flood with certain intensity without professional use training.

s5: longitudinally splicing the box body: after the box body (1) of the first layer is transversely spliced, firstly, sand bags are filled into the spliced box body (1) of the first layer, then, the box body (1) of the second layer is positioned by utilizing a positioning groove (5) and a positioning bulge (6) which are correspondingly arranged, the sand bags are filled into the box body of the second layer after the positioning, the analogy is carried out in sequence, after the height required by flood prevention is reached, the assembled transverse fixing loop bar sequentially penetrates through a transverse fixing sleeve (3) of the flood prevention sand box, the flood prevention sand box is transversely spliced and fixed, a loop (4) of the transverse fixing loop bar is aligned to a foundation pit, the assembled longitudinal fixing loop bar sequentially penetrates through a longitudinal fixing sleeve (2) of the flood prevention sand box and is inserted into the foundation pit, and the grounding fixing loop bar sequentially penetrates through the loop (4) and is fixed into the foundation pit, so that the integral splicing and fixing of the box body is completed;
s6: the box body is disassembled: after the flood season is over, the grounding fixed sleeve rod, the longitudinal fixed sleeve rod and the transverse fixed sleeve rod are sequentially pulled out and disassembled, a screw penetrating the middle of the bottom frame (101) is pulled out, sand bags in the box body (1) are unloaded and collected, a nut screw for assembling the box body is pulled out, and the box body is unfolded, flatly placed, collected and stored.
