[0028] Embodiment 1
[0029] The first embodiment of the present utility model discloses a protection structure for a waterlogged roadbed slope of a highway. Referring to Figures 1 to 5 , a protection structure for a waterlogged roadbed slope of a highway includes a plurality of retaining wall blocks 1 and a plurality of protection plates 2; a feeding port 3 is opened at the top of the retaining wall block 1, two insertion slots 4 are opened on one side of the retaining wall block 1, two insertion blocks 5 are fixedly connected to the other side of the retaining wall block 1, a fitting slot 6 is opened at the top of the retaining wall block 1, and a fitting block 7 is fixedly connected to the bottom of the retaining wall block 1. The retaining wall blocks 1 can be end-connected and stacked up and down.
[0030] The protective structure has the advantages of simple construction, low difficulty, high efficiency, low cost, water operation, and convenient maintenance. It can effectively prevent the collapse and landslide of the highway subgrade slope affected by waterlogging, ensuring the safe and unobstructed traffic of the highway. At the same time, the use of precast assembled gravity retaining wall blocks 1 and precast reinforced slope protection plates 2 can also reduce the construction difficulty and cost, facilitate the recycling of waste materials, and have good economic and environmental benefits.
[0031] Specifically, a dovetail groove 8 is formed on one side of the protection plate 2, and a dovetail block 9 is fixedly connected to the other side of the protection plate 2. One protection plate 2 is inserted and assembled into the dovetail groove 8 of another protection plate 2 through the dovetail block 9.
[0032] Specifically, four insertion holes 10 are formed on the side surface of the protection plate 2, and two protection plates 2 are connected by a U-shaped steel bar 11.
[0033] Specifically, both the retaining wall block 1 and the protection plate 2 are prefabricated products (concrete prefabricated products) that can be mass-produced.
[0034] At the base edge of the subgrade of the waterlogged road, the retaining wall blocks 1 are assembled in sequence. After assembling one retaining wall block 1, the two insertion blocks 5 of another retaining wall block 1 are inserted into the insertion grooves 4 on the first retaining wall block 1, thus completing the assembly of the two retaining wall blocks 1. In this way, the retaining wall blocks 1 are assembled at the base edge of the subgrade, and then the protection plates 2 are assembled at the subgrade slope, and the protection plates 2 are made to cover the subgrade slope. Finally, construction waste is put into the feeding port 3 to reinforce the retaining wall blocks 1. When the water level rises, the operator can stack a layer of retaining wall blocks 1 on the top of the retaining wall blocks 1. When the fitting block 7 contacts the fitting groove 6, the stability of the stacked retaining wall blocks 1 can be increased. This structural design, based on the design concept of prefabricated assembly, combines factory prefabrication with on-site assembly. The precast assembled gravity retaining wall is composed of the retaining wall blocks 1, steel pipes 12, recycled asphalt pavement milling materials, protection plates 2, etc., and has good stability, corrosion resistance, and strong load-bearing and wave resistance capabilities. This structure can not only effectively prevent slope collapse and landslide, but also reduce the construction difficulty and cost. At the same time, it is also conducive to the recycling of waste materials, and can significantly shorten the construction time. It is especially suitable for construction sites with limited space and complex traffic conditions such as highway emergency rescue, and can quickly maintain and repair highway slopes.

A flange 16 is welded between the steel pipe 12 and the extension pipe 13, and the two flanges 16 are connected by bolts.
[0037] After the first retaining wall block 1 is assembled, two steel pipes 12 are assembled in the feeding port 3 of the retaining wall block 1 to fix the position of the retaining wall block 1, thereby increasing the stability of the retaining wall block 1. When stacking and piling up the retaining wall blocks 1, the extension pipe 13 can be inserted into the steel pipe 12 to increase the stability of the second layer of retaining wall block 1.
