The sleeve includes an outer sleeve 2 and an inner sleeve 3. The outer sleeve 2 is sleeved on the upper part of the inner sleeve 3, and the lower part of the inner sleeve 3 is installed in the column 1. The bottom end of the outer sleeve 2 is connected to the top of the column 1 through the inner sleeve 3; the outer sleeve 2 is provided with a C-shaped crossbeam 4, and the C-shaped crossbeam 4 is arranged above the corrugated plate 12. The connection between the outer sleeve 2 and the C-shaped crossbeam 4 is provided with a first U-shaped connector 5; the opening of the C-shaped crossbeam 4 faces the first U-shaped connector 5, and the upper and lower sides of the C-shaped crossbeam 4 are connected to the upper and lower sides of the first U-shaped connector 5.

[0035] Furthermore, the outer diameter of the outer sleeve 2 is consistent with the outer diameter of the column 1 , and the outer diameter of the inner sleeve 3 is smaller than the inner diameter of the column 1 .

[0036] Working principle and effect: When modifying the original guardrail, there is no need to dismantle the column 1 of the original guardrail. It is only necessary to add a sleeve structure and a C-shaped beam 4 structure to the column 1. Specifically, by inserting the bottom end of the inner sleeve 3 into the interior of the column 1, the outer sleeve 2 sleeved on the upper end of the inner sleeve 3 is connected to the column 1, thereby achieving the purpose of heightening the column 1, and then the anti-obstruction block 11 is installed and fixed on the column 1, the corrugated plate 12 is installed and fixed on the anti-obstruction block 11, the first U-shaped connecting piece 5 is installed and fixed on the top of the outer sleeve 2, and the C-shaped beam 4 is installed and fixed on the first U-shaped connecting piece 5, and the modification and installation can be completed.

[0037] Compared with the prior art, the present application makes full use of the column 1 (component material of the original guardrail), does not need to completely dismantle the original guardrail facilities, saves materials to a certain extent, meets the economic construction goals and green environmental protection concepts, and raises the column 1 by combining the inner and outer sleeves 2 to increase the protective height of the guardrail. The existing guardrail is modified by using the C-shaped beam 4 to enhance the overall stiffness of the structure, which can significantly improve the protective capability of the corrugated plate 12 and better protect the safety of people's lives and property and the safety of highway operations.

[0038] Furthermore, during the construction process, the inner sleeve 3, the outer sleeve 2, the first U-shaped connector 5 and other components can be assembled in advance and directly installed during on-site reconstruction, thereby reducing the working time of workers on the road section and reducing the risk of accidents for workers.

The second U-shaped connector 7 is installed inside the C-shaped crossbeam 4, and the opening direction of the second U-shaped connector 7 is consistent with the opening direction of the C-shaped crossbeam 4. The C-shaped crossbeam 4 is formed by splicing various segments, and each segment is light in weight. The adjacent segments are connected and fixed by the second U-shaped connector 7, which is simple to operate and easy to install.

[0044] In one embodiment, Figure 4 As shown, both the C-shaped cross beam 4 and the second U-shaped connecting member 7 are provided with mounting holes 8, and the positions of the mounting holes 8 on the C-shaped cross beam 4 and the mounting holes 8 on the second U-shaped connecting member 7 correspond to each other. Bolts can be inserted into the mounting holes 8 to lock and fix the C-shaped cross beam 4 and the second U-shaped connecting member 7.

[0045] In one embodiment, Figure 1 As shown, a column cap 13 is provided on the top of the column 1.
