When the road slope reinforcement device is used in rainy weather, the rain will moisten the water-absorbing expansion block, causing it to swell, thereby pushing the pointed pile out and pushing it into the side wall of the soil, making it more difficult for the positioning pile to fall off. The greater the rain, the faster the pointed pile is inserted into the side wall of the soil, further improving the effect of road slope reinforcement.

The road slope reinforcement device can collect rainwater by arranging a water tank. When the weather temperature is high and the soil of the road slope becomes dry and hard, if the temperature reaches the deformation temperature of the memory alloy, the memory alloy will cause the baffle to open the water outlet trough on the water tank, and at the same time, the power of the winding motor can be turned on. The winding motor causes the pull rope on the winding wheel to pull the movable plate upward, so that the movable plate pushes the rainwater upward. The rainwater flows to the ground of the slope through the water outlet trough to moisten the soil, thereby protecting the soil of the road slope.

In the embodiment of the present invention, the positioning pile 2 includes a pile foot 22, which passes through the slope protection board 1 and is inserted into the slope soil, and a limit block 21 is provided at one end of the pile foot 22, a cavity 23 is provided inside the pile foot 22, and a knob 24 is rotatably provided on the upper part of the limit block 21. One end of the knob 24 is located in the cavity 23 and is connected to a bolt rod 25, and a movable sleeve 26 is screwed on the outside of the bolt rod 25 through a thread, and connecting rods 27 are hinged at both ends of the movable sleeve 26. Through grooves 28 communicating with the interior of the cavity 23 are provided on both sides of the pile foot 22, and movable bars 29 are hinged in the through grooves 28. Cutters 210 are provided on the opposite sides of the two movable bars 29, and one end of the connecting rod 27 is hinged to one end of the movable bar 29. When the movable bar 29 is located in the through groove 28, the cutter 210 on the movable bar 29 is just located in the through groove 28.

In the above scheme: the slope protection board 1 is placed on the road slope, and then the slope protection board 1 is fixed on the slope by the positioning pile 2. When fixing, the pile foot 22 passes through the slope protection board 1 and is inserted into the slope, and then the limit block 21 is hammered to make the pile foot 22 completely inserted into the slope soil, and the slope protection board 1 is completely fixed, and then the knob 24 is turned to drive the bolt rod 25 to rotate, and the bolt rod 25 drives the movable sleeve 26 to move downward. When the movable sleeve 26 moves, the connecting rod 27 drives the movable bar 29 to rotate. Under the obstruction of the protrusion 211, the lower end of the movable bar 29 will rotate outward, and under the action of the cutter 210, as the movable bar 29 rotates, the cutter 210 will be inserted into the soil side wall, so that the cutter 210 is stuck in the soil side wall, so that when the pile foot 22 is disengaged outward, the cutter 210 will play a blocking role to prevent the pile foot 22 from disengaging.

Further, please refer to Figures 2 and 3. In the embodiment of the present invention, protrusions 211 are provided at the two edges of the lower side of the cavity 23. The protrusions 211 just block the lower end of the movable bar 29 away from the cutter 210. When the connecting rod 27 drives the movable bar 29 to rotate, the lower end of the movable bar 29 will rotate outward under the obstruction of the protrusions 211, so that the cutter 210 is stuck in the soil.

The second embodiment is different from the first embodiment in that:

Please refer to Figures 2 and 4. In the embodiment of the present invention, a cavity 291 is provided inside the movable bar 29. The cavity 291 extends to both ends of the movable bar 29, and a fixed block 292 is provided inside the upper part of the cavity 291. A water-absorbing expansion block 294 is fixedly provided at one end of the fixed block 292, and the fixed block 292 is densely covered with through holes 293 for rainwater to wet the water-absorbing expansion block 294 through the through holes 293.

Please refer to Figures 2 and 4. In the embodiment of the present invention, when the water-absorbing expansion block 294 is in a dry state, the sharp stake 295 is completely in the cavity 291, and when the water-absorbing expansion block 294 is in a wet state, the water-absorbing expansion block 294 pushes out one end of the sharp stake 295 to insert it into the soil.

The knob 24 and the bolt rod 25 are both provided with slots inside, and the two slots are connected, so that rainwater can flow from the slots on the knob 24 and the bolt rod 25 into the cavity 23 inside the pile foot 22.

In the above scheme: when it rains, rainwater will flow into the knob 24 and the notches on the bolt rod 25, enter the cavity 23 inside the pile foot 22, and then enter the cavity 291 inside the movable bar 29, and moisten the water-absorbing expansion block 294 through the through hole 293 on the fixed block 292. The water-absorbing expansion block 294 will expand and push the sharp pile 295 outward, so that the sharp pile 295 is inserted into the side wall of the soil, further reinforcing the pile foot 22. The heavier the rain, the faster the sharp pile 295 is inserted into the soil, making it difficult for the slope protection board 1 to slide down the road slope.

Embodiment 3 is different from Embodiment 1 in that:

Please refer to Figures 5 and 6. In the embodiment of the present invention, the road slope reinforcement device also includes a slope soil protection mechanism 4. The slope soil protection mechanism 4 includes a water tank 41 embedded in the road. The upper part of the water tank 41 is flush with the road, and the upper part of the water tank 41 is densely covered with water filter holes 42. A water outlet trough 43 connected to the interior of the water tank 41 is provided at the upper part of one side of the water tank 41, and the water outlet trough 43 extends away from one side of the water tank 41 to the road slope.

Please refer to Figure 6. In the embodiment of the present invention, a winding motor 44 is installed on the upper side of the water tank 41 away from the water outlet trough 43. The output shaft of the winding motor 44 is located at an internal position of the water tank 41 and is connected to a reel 45. A pull rope 48 is wound inside the reel 45. One end of the pull rope 48 is connected to a movable plate 46. The size of the movable plate 46 is compatible with the internal size of the water tank 41, and the movable plate 46 is longitudinally slidably arranged in the water tank 41. The slope soil protection mechanism 4 also includes a protection auxiliary mechanism 47.

Please refer to Figures 5 to 7. In the embodiment of the present invention, the protective auxiliary mechanism 47 includes a limit bar 471 arranged at the upper part of the inner wall of the water storage tank 41, and the lower part of the limit bar 471 is connected to a T-shaped shaft 472. The outer longitudinal sliding sleeve of the T-shaped shaft 472 is provided with a moving block 473, and the outer part of the T-shaped shaft 472 is also provided with a spiral memory alloy 474. The two ends of the memory alloy 474 are respectively connected to the lower part of the limit bar 471 and the upper part of the moving block 473. One end of the moving block 473 is provided with a baffle 475, and the baffle 475 is attached to the inner wall of the water storage tank 41. The upper part of the baffle 475 is provided with a conductive block 476, and the lower part of the limit bar 471 is provided with a conductive block 476. The conductive block 2 477 corresponding to the block 1 476, the conductive block 1 476 and the conductive block 2 477 are electrically connected to the winding motor 44 through wires, and the winding motor 44 is powered by the street lamp power supply on the road. When the conductive block 1 476 and the conductive block 2 477 are in contact, a series circuit is formed between the street lamp power supply and the winding motor 44, the conductive block 1 476 and the conductive block 2 477, so that the winding motor 44 works. The output shaft of the winding motor 44 is non-self-locking, so that after the winding motor 44 is powered off, its output shaft can rotate freely under external force, so that under the gravity of the movable plate 46, the movable plate 46 will slide downward, so that the water storage tank 41 can collect the next rainwater.

Please refer to Figures 5 to 7. In the embodiment of the present invention, the memory alloy 474 will shorten and deform when the temperature is above 50 degrees, and will return to its original shape when the temperature is below 40 degrees. When the memory alloy 474 is at its original length, the baffle 475 just covers the water outlet 43 on the water tank 41. After the memory alloy 474 reaches the deformation temperature and shortens, the baffle 475 just opens the water outlet 43, and the conductive block 1 476 on the baffle 475 just contacts the conductive block 2 477 at the bottom of the limit strip 471.

In the above scheme: when it rains, rainwater will enter the water storage tank 41 through the water filter hole 42 and be stored therein. When the external temperature is high and the temperature above the water storage tank 41 reaches 50 degrees, the memory alloy 474 will reach the deformation temperature, and the memory alloy 474 will shorten, so that it drives the moving block 473 to slide upward on the T-shaped shaft 472, thereby driving the baffle 475 to move upward. The baffle 475 opens the water outlet trough 43 on the water storage tank 41, and the conductive block 1 476 on the baffle 475 will contact the conductive block 2 477 at the bottom of the limit strip 471, thereby connecting the power of the winding motor 44, and the winding motor 44 will drive the reel 45 to rotate, and the reel 45 will rotate. The wheel 45 reels the pull rope 48, thereby pulling the movable plate 46 upward, and the movable plate 46 pushes the rainwater upward, so that it flows from the water outlet trough 43 to the soil on the slope, and moistens the dry soil. When the temperature above the inside of the water storage tank 41 is lower than 40 degrees, the memory alloy 474 will restore its original length, so that the baffle 475 will block the water outlet trough 43. In this way, after the rainwater enters the water storage tank 41, the rainwater will not flow out of the water outlet trough 43, and the conductive block 1 476 and the conductive block 2 477 will not contact, so that the winding motor 44 is powered off, and under the gravity of the movable plate 46, the movable plate 46 will slide downward, so that the water storage tank 41 can collect the next rainwater.

Working principle: Place the slope protection board 1 on the road slope, and then fix the slope protection board 1 on the slope through the positioning pile 2. When fixing, pass the pile foot 22 through the slope protection board 1 and insert it into the slope, then hammer the limit block 21 to make the pile foot 22 completely inserted into the slope soil, and completely fix the slope protection board 1;

Then, the knob 24 is turned to drive the bolt rod 25 to rotate, and the bolt rod 25 drives the movable sleeve 26 to move downward. When the movable sleeve 26 moves, the connecting rod 27 drives the movable bar 29 to rotate. Under the obstruction of the protrusion 211, the lower end of the movable bar 29 rotates outward, and under the action of the cutter 210, as the movable bar 29 rotates, the cutter 210 is inserted into the soil side wall, so that the cutter 210 is stuck in the soil side wall, so that when the pile foot 22 is separated outward, the cutter 210 will play a blocking role to prevent the pile foot 22 from separating;

When it rains, rainwater will flow from the notches on the knob 24 and the bolt rod 25, into the chamber 23 inside the pile foot 22, and then into the chamber 291 inside the movable bar 29, and wet the water-absorbing expansion block 294 through the through hole 293 on the fixed block 292. The water-absorbing expansion block 294 will expand and push the sharp pile 295 outward, so that the sharp pile 295 is inserted into the side wall of the soil, further reinforcing the pile foot 22. The greater the rain, the faster the sharp pile 295 is inserted into the soil, making it difficult for the slope protection board 1 to slide down from the road slope;

When it rains, rainwater will enter the water storage tank 41 through the water filter hole 42 and be stored therein. When the external temperature is high and the temperature above the water storage tank 41 reaches 50 degrees, the memory alloy 474 will reach the deformation temperature, and the memory alloy 474 will shorten, so that it drives the moving block 473 to slide upward on the T-shaped shaft 472, thereby driving the baffle 475 to move upward, and the baffle 475 will open the water outlet 43 on the water storage tank 41, and the conductive block 1 476 on the baffle 475 will contact the conductive block 2 477 at the bottom of the limit strip 471, thereby connecting the power of the winding motor 44, and the winding motor 44 will drive the reel 45 to rotate, and the reel 45 The pull rope 48 is reeled in, thereby pulling the movable plate 46 upward, and the movable plate 46 will push the rainwater upward, causing it to flow from the water outlet trough 43 to the soil on the slope, thereby moistening the dry soil. When the temperature above the inner part of the water storage tank 41 is lower than 40 degrees, the memory alloy 474 will restore its original length, causing the baffle 475 to block the water outlet trough 43. In this way, after the rainwater enters the water storage tank 41, the rainwater will not flow out of the water outlet trough 43, and the conductive block 1 476 and the conductive block 2 477 will not contact, so that the winding motor 44 is powered off, and under the gravity of the movable plate 46, the movable plate 46 will slide downward, so that the water storage tank 41 can collect the next rainwater.
