In this embodiment, the slope fixing mechanism 2 is installed on the inclined surface of the slope bank 1. On the one hand, it can reinforce the soil layer of the slope bank 1 to prevent landslides. On the other hand, it can support the bank protection body 3 to reduce the pressure on the soil layer of the slope bank 1 and avoid depressions. Among them, the prefabricated block 301 is a rectangular block, and the prefabricated block 301 is installed above the slope fixing mechanism 2 and is not in direct contact with the slope surface; the planting layer 303 is preferably organic soil, and a layer of pebbles is laid above the planting layer 303 to support the stems of the plants; the water collecting chamber 304 is arranged on one side of the planting trough 302, and the water collecting chamber 304 is a closed structure to reduce the evaporation of water. At the same time, connecting holes are arranged on the front and rear sides of the water collecting chamber 304. During installation, it should be ensured that the connecting holes on the front and rear two adjacent prefabricated blocks 301 are aligned so that the two adjacent water collecting chambers 304 in the downward direction along the slope surface are connected. A water reservoir is also arranged on the top of the slope bank 1 for collecting rainwater, and the connecting port on the uppermost prefabricated block 301 is connected to the water outlet at the bottom of the water reservoir, so as to replenish the water collecting chamber 304;The siphon 305 is used to suck out the water in the water collecting chamber 304, so as to water the plants in the planting trough 302, and one end of the siphon 305 located in the planting trough 302 is lower than the other end, and a piston plate that can slide up and down is also provided in the water collecting chamber 304, and the bottom of the piston plate is connected to the inner bottom wall of the water collecting chamber 304 through a first spring. When water is poured above the piston plate, the increase in water volume will gradually compress the first spring to move the piston plate downward, so that more water can be stored in the water collecting chamber 304. Conversely, when the siphon 305 absorbs water outward, the decrease in water volume will cause the first spring to gradually The mounting frame 308 is fixed to the side wall of the planting trough 302 close to the water collecting chamber 304 by fastening bolts, and the mounting frame 308 is a U-shaped structure, which plays a role in supporting the guide tube 307 and the diversion groove 310; the rubber plug 306 is a conical plug, and the small end of the conical plug is arranged upward to block the pipe mouth of the siphon tube 305, and the diameter of the large end of the conical plug is smaller than the inner diameter of the guide tube 307, so that the water in the siphon tube 305 can pass through the rubber plug 3 06 and the gap between the guide tube 307 and flow down; the heat expansion airbag 309 is filled with heat expansion gas, and the heat expansion airbag 309 is provided with a second spring, and the two ends of the second spring are respectively connected to the upper and lower ends of the heat expansion airbag 309. When the weather is hot, the gas in the heat expansion airbag 309 will expand due to the heat, thereby pushing the guide tube 307 to rotate, so that the rubber plug 306 is separated from the siphon tube 305. On the contrary, when the weather is cool, the heat expansion airbag 309 will not expand. At this time, the second spring will tighten one end of the guide tube 307 so that the rubber plug 306 blocks the pipe mouth of the siphon tube 305 to prevent water from flowing out. ; The shunt pipe 311 is an L-shaped structure, and a longer section of the shunt pipe 311 is transversely pre-buried in the planting layer 303. The shunt groove 310 can evenly disperse water into a plurality of shunt pipes 311, thereby evenly replenishing water to the planting layer 303. In addition, when water flows out from the bottom of the guide pipe 307, it will flow down along the surface of the thermal expansion airbag 309, thereby cooling the thermal expansion airbag 309, causing the thermal expansion airbag 309 to shrink and the rubber plug 306 to block the pipe opening of the siphon pipe 305 again, so as to realize intermittent automatic water replenishment to the planting layer 303 and prevent the soil of the planting layer 303 from being too wet. ;

[0030] Specifically, the guide tube 307 is an L-shaped structure, and the size of the pipe opening of the guide tube 307 close to one end of the siphon tube 305 is larger than the size of the pipe opening of the siphon tube 305 to prevent water from splashing out.

[0031] Specifically, two groups of oppositely arranged and mutually cooperating male lock buckles 312 and female lock buckles 313 are provided on the side of the prefabricated block 301. In this embodiment, the rear side and left side of the prefabricated block 301 are provided with male lock buckles 312, and the front side and right side of the prefabricated block 301 are provided with female lock buckles 313. The male lock buckles 312 and the female lock buckles 313 are mutually buckled, so that two adjacent prefabricated blocks 301 can be connected as one.

[0032] Specifically, a rubber damping block 314 is further provided at the bottom of the prefabricated block 301. In this embodiment, the rubber damping block 314 is located between the prefabricated block 301 and the support frame 21, and can buffer the impact of waves or heavy objects on the prefabricated block 301 to prevent the slope from deforming.

[0033] Specifically, the slope fixing mechanism 2 includes a support frame 21, a mounting seat 22, a support column 23, an insertion rod 24 and a driving unit 25. The four corners of the bottom of the support frame 21 are all provided with mounting seats 22. The top end of the support column 23 is hinged to the mounting seat 22. The bottom end of the support column 23 is a pointed end. A first through hole 231 is transversely provided on the side of the support column 23. The insertion rod 24 is slidably connected in the first through hole 231. The insertion rod 24 is connected with a driving unit 25, which can drive the insertion rod 24 to move. In this embodiment, the support frame 21 is a rectangular frame, and when installed, the top surface of the support frame 21 should be parallel to the slope surface of the slope bank 1. The mounting seat 22 is a cylindrical structure, and a hinge seat is provided at the bottom of the mounting seat 22 for hingedly fixing the support column 23 so that the support column 23 can rotate to adapt to the installation of slopes with different inclinations. The inserted rod 24 can be inserted into the soil layer laterally after the support column 23 is completely inserted into the soil layer of the slope bank 1, so as to play a role in assisting in fixing the support column 23 and improving the reinforcement effect.

[0034] Specifically, the driving part 25 includes a first rotating shaft 251, a first rotating gear 252, a universal joint 253, and a second rotating shaft 254. A working chamber 232 is provided in the support column 23. The first rotating shaft 251 is rotatably connected in the working chamber 232. The first rotating gear 252 is fixedly provided on the first rotating shaft 251, and the first rotating gear 252 is meshed with the tooth groove on the insertion rod 24. The second rotating shaft 254 is rotatably connected to the mounting seat 22. The top end of the first rotating shaft 251 extends out of the working chamber 232 and is connected to the bottom end of the second rotating shaft 254 through the universal joint 253. In this embodiment, the central axis of the first rotating shaft 251 coincides with the central axis of the support column 23. When the first rotating shaft 251 rotates, it can drive the first rotating gear 252 to rotate synchronously, so that the insertion rod 24 slides horizontally, so that the tip of the insertion rod 24 can extend out of the first through hole 231 and be inserted into the soil layer. The universal joint 253 allows the first shaft 251 and the second shaft 254 to be transmitted at any angle. The central axis of the second shaft 254 coincides with the central axis of the mounting seat 22, and the bottom end of the second shaft 254 is flush with the bottom end surface of the mounting seat 22, and the top end of the second shaft 254 is flush with the top end surface of the support frame 21.

[0035] Specifically, an adjustment socket 255 is provided on the top of the second rotating shaft 254. In this embodiment, the adjustment socket 255 is a hexagon socket.

[0036] Working principle: When the weather is hot, the air in the heat expansion airbag 309 expands due to the heat, which in turn pushes the guide tube 307 to rotate so that the rubber plug 306 is separated from the siphon tube 305. At this time, the rainwater in the water collecting chamber 304 passes through the siphon tube 305 and the guide tube 307 in turn and falls into the diversion groove 310, and is diverted by the diversion tube 311 to achieve uniform watering of the planting layer 303. At the same time, when the water flows down the guide tube 307, it will also fall on the heat expansion airbag 309, thereby cooling the heat expansion airbag 309 and causing it to shrink, thereby causing the guide tube 307 to reverse and the rubber plug 306 to block the siphon tube 305 again, so as to achieve intermittent watering operations, avoid excessive watering at a single time and cause the planting layer 303 to be too wet, which helps to improve the survival rate of the plants.

[0037] This embodiment also provides a construction method of a combined ecological revetment, comprising the following steps:

[0038] Step 1: Clean the river bank 1 to ensure that the slope is flat and clean;

[0039] Step 2: Install the slope fixing mechanism 2. First, insert the support column 23 with the tip facing downward into the slope bank 1, and ensure that the top surfaces of the adjacent support frames 21 are flush, and ensure that the support frame 21 is parallel to the slope surface of the slope bank 1. Then, rotate the second rotating shaft 254 to drive the insertion rod 24 to be inserted horizontally into the soil layer of the slope bank 1, so as to firmly install the support frame 21 on the slope bank 1.

[0040] Step 3: Install the revetment body 3, place the greening units on the support frame 21 in sequence, and make the prefabricated blocks 301 of two adjacent greening units engage with each other to achieve fixation;

[0041] Step 4: Plant plants in the planting layer 303 to complete the construction work.
