Break plugging caisson for aviation rescue
The invention relates to a breach plugging caisson for aviation rescue, which comprises fixed box groups, the top of each fixed box group is provided with a lifting and hanging assembly, a main box body comprises a sealing plate and a baffle of an arch structure, the two fixed box groups are respectively sleeved at the two ends of the sealing plate, and the inner surface of the sealing plate and the inner surface of the baffle jointly define a buffer cavity. The two ends of the baffle are inserted into the fixed box set, and when the outer surface of the baffle is impacted, the two ends of the baffle stretch out and draw back in the fixed box set. According to the caisson, the problem that for a contraction type river channel, gaps are easily formed when the two sides of the caisson make contact with a crevasse, and therefore water easily flows through the gaps between the caisson and the crevasse is solved. The problems that water flow at the crevasse is torrential, and when the cross sectional area is reduced, the flow speed is increased, so that the impact force on the edge of the crevasse is increased, the crevasse is further easily enlarged, the effect of blocking the crevasse of the caisson is lost, and the blocking effect is poor are solved.
本发明涉及一种航空救援用封堵决口沉箱，包括固定箱组，所述固定箱组顶部设置提挂组件，主箱体包括封板和呈拱形结构的挡板，两个所述固定箱组分别套设在封板的两端，封板内表面与挡板内表面共同围成缓冲腔，所述挡板的两端插接在固定箱组内，且在挡板外表面受到冲击时，挡板的两端在固定箱组内伸缩活动。本发明解决了对于收缩型河道，沉箱两侧在与决口接触时容易形成缝隙，从而容易导致水从沉箱与决口之间的缝隙流过。由于决口处的水流湍急，当横截面积减小时，使得流速增大，从而增大对决口边缘的冲击力，进而容易进一步导致决口扩大，使沉箱失去封堵决口的作用，封堵效果较差的问题。
