DETAILED DESCRIPTION

[0026] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, a roadbed slope protection structure in this embodiment includes a lower plate 1, which can be used against the slope. When used for a long time, the liquid concrete in the cavity 5 can flow into the ground along the diversion hole 6 through the plug-in rod 7, so as to reinforce the soil inside the slope.

[0028] In this embodiment, in order to facilitate the fixing of the lower plate 1 on the slope, a plurality of spaced and transparent circular holes 2 are opened on the lower plate 1, and a rotatable spiral rod 3 is inserted in each circular hole 2. The lower plate 1 is first placed against the slope, and then the spiral rod 3 is inserted into the soil through the circular hole 2. A hexagonal groove 4 is provided at the upper end of the spiral rod 3, and a circular ring is fixed at the upper end of the spiral rod 3, and the internal shape of the circular ring is hexagonal. A limiting ring for the circular ring to abut is provided on the circular hole 2. When the spiral rod 3 is inserted, the circular ring can abut against the limiting ring, and the spiral rod 3 can be screwed into the soil of the slope through the hexagonal groove 4 to fix the lower plate 1 on the slope. After that, the user inserts a hexagonal screwdriver into the hexagonal groove 4 and then rotates it so that the spiral rod 3 can be screwed into the soil to fix the lower plate 1 on the slope.

[0029] In order to be able to fill and reinforce the interior of the soil, in this embodiment, a cavity 5 is provided in the spiral rod 3, and the cavity 5 is connected to the hexagonal groove 4, and a plurality of transparent diversion holes 6 are opened on the inner wall of the cavity 5. When filling and reinforcement are required, the plug-in rod 7 is first pulled out of the cavity 5, and then the liquid concrete is poured into the cavity 5 from the hexagonal groove 4. The cavity 5 is inserted with a plug-in rod 7 that can be inserted and extended along the cavity 5. The cavity 5 is provided with liquid concrete, and the plug-in rod 7 can extrude the liquid concrete along the diversion hole 6 to fill and reinforce the soil. Thereafter, the plug-in rod 7 is inserted along the cavity 5 so that the liquid concrete can be squeezed, and the liquid concrete is squeezed into the soil of the slope along the diversion hole 6 to improve the firmness of the soil.

[0030] When filling and reinforcement are not required, the insertion rod 7 is located inside the cavity 5 and can block the diversion hole 6 to prevent soil from flowing into the cavity 5 .

[0031] In order to apply pre-tightening force to the lower plate 1 and the upper plate 8, in this embodiment, a detachable upper plate 8 is provided on the lower plate 1, and the upper plate 8 and the lower plate 1 are buckled together to form a frame structure; the lower plate 1 and the upper plate 8 are snap-connected, and the specific snap-connecting structure and principle belong to the prior art and will not be described in detail here.

[0032] Specifically, an auxiliary support assembly 9 is provided under the frame structure, and the auxiliary support assembly 9 is used to clamp the upper plate 8 and the lower plate 1 to increase the preload force of the lower plate 1. The auxiliary support assembly 9 is arranged on the upper plate 8 and the lower plate 1, and the upper plate 8 and the lower plate 1 are clamped, which can increase the preload force and improve stability.

[0033] The auxiliary support assembly 9 includes a fixed seat 901 and a movable clamping plate 902. The top of the fixed seat 901 is provided with a plug-in slot 10 for plugging into the frame structure. One side of the plug-in slot 10 is provided with a sliding slot opening toward one side of the frame structure. The clamping plate 902 is slidably arranged in the sliding slot, and the upper plate 8 and the lower plate 1 are inserted into the plug-in slot 10 after being interlocked with each other.

[0034] A screw 11 is rotatably provided on one side of the clamping plate 902 away from the plug-in slot 10. The screw 11 passes through a fixing seat 901 and is fixed with a handle 12. The screw 11 is threadedly connected to the fixing seat 901. The screw 11 rotates to drive the clamping plate 902 to move along the sliding slot, thereby clamping the frame structure. The user manually rotates the handle 12 so that the handle 12 can drive the screw 11 to rotate, thereby driving the clamping plate 902 to move along the sliding slot until the clamping plate 902 stops when it abuts against the upper plate 8.

[0035] The bottom of the fixing seat 901 is fixed with a plurality of spaced and vertically arranged fixing nails 13, which are inserted into the soil to fix the fixing seat 901 on the soil. When the upper plate 8 and the lower plate 1 are inserted into the plug-in groove 10, the fixing nails 13 can also be inserted into the soil to fix the fixing seat 901.

[0036] In order to be convenient and beautiful during use, in this embodiment, a ring-shaped placement groove 14 with an opening toward one side of the upper plate 8 is opened on the lower plate 1, and an absorbent cloth 15 corresponding to the placement groove 14 is arranged in the placement groove 14. The arrangement of the absorbent cloth 15 allows rainwater to be stored in the absorbent cloth 15.

[0037] A plurality of culture troughs 16 are provided on the upper plate 8, and transparent small holes are opened on the culture troughs 16. The small holes and the absorbent cloth 15 correspond to each other up and down, so that rainwater falling into the culture troughs 16 can flow through the small holes to the absorbent cloth 15 for water storage. Vegetation is planted in the culture troughs 16, so that the slope can be beautiful during the protection process.

[0038] Vegetation is arranged in the culture tank 16, and the absorbent cloth 15 can supply water to the vegetation through the small holes, and the vegetation can absorb the water on the absorbent cloth 15 through the small holes, thereby playing the role of reusing rainwater to achieve the purpose of saving resources.

[0039] Working principle: first place the lower plate 1 against the slope, then insert the spiral rod 3 through the round hole 2 into the soil, then the user inserts the hexagonal screwdriver into the hexagonal groove 4, and then rotates it so that the spiral rod 3 can be screwed into the soil, so as to fix the lower plate 1 on the slope. When filling and reinforcement are required, first pull the connecting rod 7 out of the cavity 5, then pour the liquid concrete from the hexagonal groove 4 into the cavity 5, and then insert the connecting rod 7 along the cavity 5 so that the liquid concrete can be squeezed, and the liquid concrete is squeezed out into the soil of the slope along the diversion hole 6 to improve the firmness of the soil.

[0040] When filling and reinforcement are not required, the insertion rod 7 is located inside the cavity 5 and can block the diversion hole 6 to prevent soil from flowing into the cavity 5 .

[0041] After the upper plate 8 and the lower plate 1 are buckled together, they are inserted into the insertion groove 10, and at the same time, the fixing nail 13 is inserted into the soil to fix the fixing seat 901. Then the user manually rotates the handle 12 so that the handle 12 can drive the screw 11 to rotate, so as to drive the clamping plate 902 to move along the sliding groove until the clamping plate 902 abuts against the upper plate 8 and stops, clamping the upper plate 8 and the lower plate 1, which can increase the preload force and improve stability.

[0042] Planting vegetation in the culture trough 16 makes the slope beautiful during the protection process, and the moisture of the vegetation absorbs the rainwater stored in the absorbent cloth 15 through the small holes, thereby playing a role in reusing rainwater to achieve the purpose of saving resources.
