Support components symmetrically arranged with respect to the chassis 1 are slidably connected to the outer walls of the guide rails 2. First sliding grooves 11 are provided on both side walls of the chassis 1, and a second sliding groove 12 is further provided on the top wall of the chassis 1. A double-threaded screw rod 3 is rotatably connected to the top wall of the chassis 1. A linkage component for adjusting the support components is further provided on the outer wall of the chassis 1.

A sliding rod 42 is fixedly connected to the top wall of the fixing rod 4, and the sliding rod 42 passes through the second sliding groove 12 and is threadedly connected to the double-threaded screw rod 3. By arranging the support components and cooperating with the linkage component and the double-threaded screw rod 3, the two groups of support components are driven to move away from each other, thereby achieving the purpose of adjusting the support range and increasing the overall stability.

[0025] As shown Figures 2-5 in the figure, as a preferred embodiment, on the basis of the above method, further, the support components include a support plate 21 slidably connected to the outer wall of the guide rail 2, a connecting member 22 rotatably connected to the top wall of the support plate 21, a support sleeve rod 23 rotatably connected to the side wall of the connecting member 22, a support rod 24 slidably connected to the inner wall of the support sleeve rod 23, and a connecting plate 25 rotatably connected to the end of the support rod 24 away from the support sleeve rod 23. The two groups of connecting plates 25 are slidably connected by intersecting reinforcing rods 26. A connecting ring 27 cooperating with the adjusting component is further provided on the outer wall of the support sleeve rod 23. An elastic member 28 is further provided between the two groups of support plates 21. The two groups of support sleeve rods 23, support rods 24, and connecting plates 25 move away from each other, thereby achieving the purpose of adjusting the support range. The fixing rod 4 and the fixing plate 41 move away from the support plate 21, realizing the purpose of adjusting the bottom support range and increasing the overall stability.

[0026] As shown Figures 1-4 in the figure, as a preferred embodiment, on the basis of the above method, further, the linkage component includes a sliding frame 13 slidably connected to the outer wall of the chassis 1 through the first sliding groove 11 and linkage rods 14 rotatably connected to both side walls of the sliding frame 13. The ends of the two groups of linkage rods 14 away from the sliding frame 13 are respectively rotatably connected to the two groups of support plates 21, and the sliding frame 13 is threadedly connected to the double-threaded screw rod 3. The sliding frame 13 slides on the outer wall of the chassis 1. When the sliding frame 13 slides, the two groups of support plates 21 are pushed to move away from each other through the two groups of linkage rods, and the two groups of support sleeve rods 23, support rods 24, and connecting plates 25 are driven to move away from each other, thereby achieving the purpose of adjusting the support range.

[0027] As shown Figures 1-5As shown, as a preferred embodiment, on the basis of the above method, further, the adjusting member includes a connecting seat 43 rotatably connected to the top wall of the fixing plate 41, an adjusting sleeve 44 rotatably connected to the top wall of the connecting seat 43, and an adjusting screw 45 threadedly connected to the inner wall of the adjusting sleeve 44.

The outer wall of the adjusting sleeve 44 is also provided with an anti-slip groove 47. Rotating the adjusting sleeve 44 drives the adjusting screw 45 to extend, so as to achieve the purpose of adjusting the angle between the support sleeve rod 23 and the support plate 21, which can be applied to the reinforcement of cofferdams with different height specifications and increases the overall applicability.

[0028] As Figures 1-5 As shown, as a preferred embodiment, on the basis of the above method, further, the bottom wall of the support plate 21 is provided with evenly arranged conical spikes 51, the inner wall of the support plate 21 is also provided with symmetrically arranged reinforcing cones 52, and the side wall of the connecting plate 25 is also provided with symmetrically distributed connecting bolts 5.

[0029] Specifically, when the cofferdam construction reinforcement device is in use: the support plate 21 is fixed to the ground through the conical spikes 51 and the reinforcing cones 52. When it is necessary to adjust the support range, rotate the double-threaded screw rod 3, which in turn drives the reinforcing rod 26 to slide out of the chassis 1, and at the same time drives the sliding frame 13 to slide on the outer wall of the chassis 1. When the sliding frame 13 slides, it pushes the two support plates 21 away from each other through the two linkage rods, and drives the two support sleeve rods 23, the support rods 24 and the connecting plate 25 to move away from each other, so as to achieve the purpose of adjusting the support range. The fixed rod 4 and the fixing plate 41 move away from the support plate 21 to achieve the purpose of adjusting the bottom support range, which increases the overall stability. At the same time, the total length of the support rod 24 and the support sleeve rod 23 can also be adjusted to adjust the support height. Rotating the adjusting sleeve 44 drives the adjusting screw 45 to extend, so as to achieve the purpose of adjusting the angle between the support sleeve rod 23 and the support plate 21, which can be applied to the reinforcement of cofferdams with different height specifications and increases the overall applicability. After the adjustment is completed, the connecting plate 25 is fixed to the cofferdam through the connecting bolts 5 to complete the reinforcement of the cofferdam.
