[0003] After searching, the patent number CN214530241 U discloses a supporting structure for a bridge culvert. During the installation and disassembly process, the supporting structure slides on the inner side of the slide groove through the rotating shaft that is rotatably connected to the third outer guard plate and the second outer guard plate, thereby preventing the third outer guard plate and the second outer guard plate from being unable to rotate and causing the inability to install and disassemble. The sliding plate is pushed to make the arc plate squeeze the rotating shaft that is rotatably connected to the third outer guard plate and the second outer guard plate, the sliding block is used to clamp the limit plate, and the spring is used to make the push rod pass through the limit plate, so as to fix it. The operation is simple and convenient.

[0027] Before supporting the inside of the culvert, both sets of supporting structures are moved to the inside of the culvert, and the bottom plate 1 is brought into contact with the ground inside the culvert. With the insertion of the positioning pin 17, the bottom plate 1 is fixed, and then the arc sleeve 3 is unfolded from the arc sleeve 2 and brought into contact with the inner wall of the culvert. Then the first support rod 5 and the second support rod 6 are unfolded and fixed, and are tilted by the support of the fixing rod 4. Then the upper end of the second support rod 6 is connected to the internal connecting groove of the arc sleeve 3, so that the arc sleeve 2, the arc sleeve 3, the bottom plate 1 and the first support rod 5 and the second support rod 6 form a stable triangular support structure to stably support the inside of the culvert.

[0028] In order to ensure that the arc-shaped sleeve rod 3 and the second support rod 6 can be stably connected after being unfolded, as shown in FIG.
