[0018] See also Figure 1-Figure 2The utility model provides a technical solution: a bridge reinforcement base, including a base 1, a first reinforcement arm 11, a second reinforcement arm 15 and a threaded rod 2, the first reinforcement arm 11 and the second reinforcement arm 15 are in two groups, the first reinforcement arm 11 is rotatably connected to the middle part of the upper surface of the base 1, a first hinge block 12 is welded to the middle part of the upper surface of the base 1, one end of the two groups of first reinforcement arms 11 is hinged to the first hinge block 12, the two groups of first reinforcement arms 11 are symmetrically arranged, and the second reinforcement arms 15 are in two groups. The arm 15 is rotatably connected to the bottom side of the first reinforcing arm 11, and a second hinge block 16 is welded to the bottom side of the first reinforcing arm 11. One end of the second reinforcing arm 15 is hinged to the second hinge block 16. Slide grooves 13 are horizontally opened on both sides of the upper surface of the base 1. A slider 14 is slidably connected inside the slide groove 13. The other end of the second reinforcing arm 15 is hinged to the top of the slider 14. The threads on both sides of the threaded rod 2 have opposite rotation directions. The threaded rod 2 horizontally passes through the middle of the two groups of sliders 14 and is threadedly connected to the slider 14.

[0019] In this technical solution, since the threads on both sides of the threaded rod 2 rotate in opposite directions, the threaded rod 2 horizontally passes through the middle of the two groups of sliders 14 and is threadedly connected to the sliders 14. During the rotation of the threaded rod 2, the two groups of sliders 14 can be driven to move relative to or in reverse directions in the slide groove 13. When the two groups of sliders 14 move relative to each other, the second reinforcement arm 15, the second hinge block 16 and the first hinge block 12 can simultaneously adjust the use angles of the two groups of first reinforcement arms 11, and further adjust the use height of the support bar 17, so that the two groups of support bars 17 can support and reinforce both sides of the bottom end of the bridge.

[0020] In this embodiment, a turntable 21 is fixedly installed at one end of the threaded rod 2 placed on the outside of the base 1. The threaded rod 2 is rotatably connected to the middle of the base 1 through a bearing. Four groups of fixing holes 22 are opened through the outside of the base 1, and the four groups of fixing holes 22 are distributed at the four corners of the base 1.

[0021] In this technical solution, the staff drives the threaded rod 2 to rotate through the turntable 21, which is convenient for the staff to manually adjust the first reinforcement arm 11 outdoors. After adjusting the use position of the first reinforcement arm 11 and the support bar 17, the base 1 can be limited and fixed by passing the pin through the fixing hole 22 and inserted into the soil.

[0022] In this embodiment, a support bar 17 is horizontally welded to one end of the first reinforcement arm 11 away from the first hinge block 12 .

[0023] In this technical solution, the support bar 17 horizontally welded at one end of the first reinforcement arm 11 can increase the reinforcement area of ​​the bridge, thereby enhancing the reinforcement effect of the first reinforcement arm 11 on the bridge.

[0024] When a bridge reinforcement base is used, the base 1 is placed horizontally just below the bridge reinforcement position, and the staff drives the threaded rod 2 to rotate through the turntable 21. Since the threads on both sides of the threaded rod 2 rotate in opposite directions, the threaded rod 2 horizontally penetrates the middle of the two groups of sliders 14 and is threadedly connected with the sliders 14. During the rotation of the threaded rod 2, the two groups of sliders 14 can be driven to move relative to or in the opposite direction in the slide groove 13. When the two groups of sliders 14 move relative to each other, the use angles of the two groups of first reinforcement arms 11 can be adjusted at the same time through the second reinforcement arm 15, the second hinge block 16 and the first hinge block 12, and the use height of the support bar 17 can be further adjusted, so that the two groups of support bars 17 can support and reinforce both sides of the bottom end of the bridge. After the use positions of the first reinforcement arm 11 and the support bar 17 are adjusted, the base 1 can be limited and fixed by passing the pin through the fixing hole 22 and inserted into the soil.
