[0002] With the diversified development of train and railway technology, rail transit has shown more and more types and is widely used in medium and short-distance urban public transportation. Rail transit is generally divided into three categories: national railway system, intercity rail transit and urban rail transit. The most common rail transit in the city is the subway. When encountering heavy rain, the rain is heavy and the water level rises slowly. In this case, sandbags are needed at the subway entrance to keep the water out of the subway entrance.

[0003] However, the friction between the bags is small, and there is often no corresponding anti-rollover structure on both sides of the waterproof structure of the sandbags. As a result, when the sandbags are impacted by water, they may tilt or collapse, resulting in the loss of the waterproof effect. Utility Model Content

[0023] It should be noted that: the connecting assembly is fixed between the left base 1 and the right base 101, that is, the threaded column 202 on the side wall of the main frame 2 is rotated to fix it to the left base 1, and then the threaded column 202 on the side wall of the main frame 2 and the threaded sleeve 201 are used to clamp and fix each other, and finally the threaded sleeve 201 on the right side wall of the main frame 2 is fixed to the right base 1, and the connecting assembly can be assembled, and then the sandbag is placed on the outside of the connecting assembly. The connecting assembly can support the sandbag to prevent the sandbag from collapsing due to excessive force, and a connecting plate 204 can be installed on the inner wall of the sleeve 203 on the side wall of the main frame 2, and the connecting plate 204 and the sleeve 203 are fixed by the first threaded bolt 205, and then the rotating column 206 at the bottom of the connecting plate 204 is rotated to adjust the position of the support plate 207, so that the support plate 207 plays the role of supporting the connecting assembly, thereby supporting the sandbag and sharing the pressure on the sandbag.

[0024] Reference Figure 1-3 The top of the sliding column 103 is clamped with a top plate 3, and the top of the top plate 3 is threadedly connected with a second threaded bolt 301, and the second threaded bolt 301 can extend to the inner cavity of the left base 1 and the right base 101;

[0025] The top of the top plate 3 is threadedly connected with a third threaded bolt 302, and the bottom end of the third threaded bolt 302 is rotatably connected with a pressing plate 303;

[0026] It should be noted that: a top plate 3 is installed on the top of the left base 1 and the right base 101, and then the second threaded bolt 301 is rotated to fix it, and at the same time, the sliding column 103 is slid on the inner wall of the sleeve 102 to adjust the height of the top plate 3, and then the third threaded bolt 302 is rotated. The third threaded bolt 302 will drive the pressure plate 303 to press down, thereby reinforcing the sandbags located on the side walls of the connecting assembly to prevent the sandbags from being subjected to excessive impact force and becoming loose and collapsed.

[0027] Reference Figure 1-3 , the top of the pressing plate 303 is fixedly connected to a limiting column 304, and the limiting column 304 passes through the top plate 3;

[0028] The main frame 2 can be mutually clamped through the threaded sleeve 201 and the threaded column 202 on its side wall, and the side wall of the sleeve 102 is threadedly connected with a fourth threaded bolt 305;

[0029] It should be noted that: since there is a limiting column 304 on the top of the pressure plate 303, when the third threaded bolt 302 is rotated, the pressure plate 303 will not rotate with the third threaded bolt 302, but will be pressed down as the third threaded bolt 302 rotates, and the fourth threaded bolt 305 can fix the sliding column 103 on the inner wall of the sleeve 102.

[0030] Operation method: fix the connecting assembly between the left base 1 and the right base 101, that is, rotate the threaded column 202 of the side wall of the main frame 2 to fix it to the left base 1, then use the threaded column 202 of the side wall of the main frame 2 and the threaded sleeve 201 to clamp each other and fix, finally fix the threaded sleeve 201 of the right side wall of the main frame 2 to the right base 1, and the connecting assembly can be assembled. Then, place the sandbag on the outside of the connecting assembly. The connecting assembly can support the sandbag to prevent the sandbag from collapsing due to excessive force, and a connecting plate 204 can be installed on the inner wall of the sleeve 203 of the side wall of the main frame 2, and the connecting plate 204 and the sleeve 203 can be fixed by the first threaded bolt 205, and then the rotating column 206 at the bottom of the connecting plate 204 is rotated to adjust the position of the support plate 207, so that the support plate 207 can play the role of supporting the connecting assembly, thereby supporting the sandbag and sharing the pressure on the sandbag;

[0031] A top plate 3 is installed on the top of the left base 1 and the right base 101, and then the second threaded bolt 301 is rotated to fix it, and at the same time, the sliding column 103 is slid on the inner wall of the sleeve 102 to adjust the height of the top plate 3. After the adjustment is completed, the fourth threaded bolt 305 is rotated to fix the sliding column 103 on the inner wall of the sleeve 102, and then the third threaded bolt 302 is rotated. Due to the limiting column 304 on the top of the pressure plate 303, when the third threaded bolt 302 is rotated, the pressure plate 303 will not rotate with the third threaded bolt 302, but will be pressed down as the third threaded bolt 302 rotates, thereby reinforcing the sandbags located on the side walls of the connecting assembly to prevent the sandbags from being subjected to excessive impact force and becoming loose and collapsed.
