[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention provides a river ecological bank protection device and a construction scheme thereof. Through the setting of a leveling layer, a large stone layer is laid on the bottom of the water and on the shore. The purpose of laying on the bottom of the water is to support the stones on the shore and enhance stability. A high-strength geotextile is laid on the upper end of the large stone layer. Since the laying position of the large stone layer is uneven, the covering of the high-strength geotextile can enhance the stability of the large stone layer while forming a water infiltration channel. The card blocks provide card-fitting fixation for both sides of the large stone layer. After the card blocks are fixed, cement can be filled to enhance stability. At the same time, the card blocks can shield the ecological protective layer, thereby solving the problem that the existing bank protection structure is a single body and is not stable enough.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In order to solve existing technical problems, such as Figure 1-Figure 7 As shown, the following preferred technical solutions are provided:

[0038] A river ecological bank protection device comprises a bank slope bottom layer 1, a leveling layer 2 is laid flat on the upper end of the bank slope bottom layer 1, an ecological protective layer 3 is placed side by side on the upper end of the leveling layer 2, the leveling layer 2 comprises a large stone layer 21 laid flat on the upper end of the bank slope bottom layer 1, a high-strength geotextile 24 for isolating water seepage is laid on the upper end of the large stone layer 21, blocks 23 for fixing the high-strength geotextile 24 are engaged at both ends of the high-strength geotextile 24, the blocks 23 are inserted into the large stone layer 21 and fixedly arranged, a crushed stone cushion layer 25 is evenly laid on the upper end of the high-strength geotextile 24, and the ecological protective layer 3 comprises an ecological frame 31 for planting plants that is mutually engaged on the upper end of the crushed stone cushion layer 25.

[0039] Specifically, the large stone layer 21 is laid on the bottom of the water and the shore. The purpose of laying on the bottom of the water is to support the stones on the shore and enhance stability. The high-strength geotextile 24 is laid on the upper end of the large stone layer 21. Since the laying position of the large stone layer 21 is uneven, the covering of the high-strength geotextile 24 can enhance the stability of the large stone layer 21 while forming a water infiltration channel. The blocks 23 provide snap-fit ​​fixation for both sides of the large stone layer 21. After the blocks 23 are fixed, cement can be filled to enhance stability. At the same time, the blocks 23 can form a shielding effect on the ecological protective layer 3. The adjacent ecological frames 31 are snap-fitted in an arc shape. The ecological frame 31 has no bottom and is deeper inside, which can be filled with nutrient soil for planting plants. The ecological frame 31 provides a fixed space for the river bank soil to prevent it from being washed away by water. At the same time, the plants can take root downward along the leveling layer 2 to achieve ecological bank protection, which is both beautiful and effective in preventing soil erosion.

[0040] The bottom layer 1 of the bank slope provides a location for laying the leveling layer 2. The bottom layer 1 of the bank slope needs to be preliminarily processed to remove shore plants and be leveled and compacted to facilitate laying of the leveling layer 2.

[0041] The leveling layer 2 also includes a cement casting 22 fixed at the engagement between the large stone layer 21 and the block 23. The block 23 is provided with sockets 231 arranged side by side, and the lower end of the sockets 231 is provided with a latching tooth 232. The high-strength geotextile 24 is provided with a plurality of seepage ports 241 arranged in an array.

[0042] Specifically, cement casting 22 provides reinforcement for the connection between the large stone layer 21 and the block 23, thereby enhancing the service life of the entire revetment device and reserving sufficient time for the plants of the ecological revetment to take root. The socket 231 reserves a fixed space for the clamping strip 32. The clamping teeth 232 increase the friction between the block 23 and the high-strength geotextile 24, thereby stably pressing the high-strength geotextile 24. The high-strength geotextile 24 has high tensile strength, compressive strength and impact resistance. The opening of the seepage port 241 reserves water for seepage while providing rooting conditions for plants. At the same time, the high-strength geotextile 24 is an environmentally friendly material that can be recycled and reused to reduce resource consumption and environmental pollution.

[0043] The ecological protective layer 3 also includes an insertion rod 33 inserted into the corners of the adjacent ecological frame 31, and a clamping strip 32 is sleeved between the insertion rods 33. The two ends of the clamping strip 32 are inserted into the clamping block 23 for fixation. The ecological frame 31 is arranged as a bottomless frame 311, and the side of the bottomless frame 311 is provided with an upper turn 312 and a lower turn 313. The upper turn 312 and the lower turn 313 are staggered up and down on both sides, and the side ends of the upper turn 312 and the lower turn 313 are provided with an upper groove 3121 and a lower groove 3131 respectively.

[0044] Specifically, the insertion rod 33 is used to insert and fix two groups of ecological frames 31 to achieve the connection of the ecological frames 31. The clamping strip 32 realizes pressurized protection for the insertion rod 33 and the ecological frame 31, thereby enhancing the integrity of the entire bank protection device. The bottomless frame 311 provides protection for the ecological bank protection plants. The staggered arrangement of the upper bend 312 and the lower bend 313 enables adjacent ecological frames 31 to overlap and be fixed by the insertion rod 33. The upper groove 3121 and the lower groove 3131 provide insertion ports for the overlapping fixation of the ecological frame 31, thereby ensuring the connection effect of the ecological frame 31.

[0045] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a construction scheme of a river ecological bank protection device, comprising the following steps:

[0046] Step 1: Foundation treatment: Ecological revetment requires foundation treatment, excavation, leveling, and compaction to create conditions for subsequent construction;

[0047] Step 2: Stone riprap footing: After leveling and compaction, stone riprap footing is constructed, and large stones are thrown into the water and the shore to form a slope to protect the river bank and reduce the erosion of the river bank by the water flow. At this time, pay attention to the reserved bayonet 211;

[0048] Step 3: Fabric laying: Lay the high-strength geotextile 24 on the large stone layer 21. The seepage port 241 is used for water infiltration. The high-strength geotextile 24 is woven with high-strength fibers and has good drainage performance. It can reduce the problem of water accumulation and retention on the surface and prevent scouring and erosion caused by surface water flow. At the same time, the high-strength geotextile 24 has good corrosion resistance and can operate stably for a long time under different soil and water quality environments. The two sides of the high-strength geotextile 24 are fixed by the engagement of the clamping block 23 in the clamping port 211.
