[0002] River embankment slope protection refers to a series of engineering measures and technical means taken to prevent river embankment slopes from being damaged by natural forces such as water scouring and soil erosion. Its main purpose is to protect the stability of the river embankment, prevent soil erosion, and ensure the safety and durability of the river embankment.

[0003] However, traditional embankment slope protection methods usually use mortared stone and concrete slope protection. Although they can prevent slope collapse and water erosion to a certain extent, since both are hard materials, they completely cover the slope surface, hindering the natural growth of vegetation and destroying the original ecosystem. At the same time, the appearance of hard slope protection is simple and rigid, which is inconsistent with the surrounding natural environment, seriously affecting the landscape beauty along the river and reducing people's appreciation of the natural landscape. Summary of the Invention

The surface of the adjusting column is slidably connected to the inner cavity of the anchor rod, and an annular guide groove is provided on the surface of the adjusting column. An inserted column is slidably connected between the surface of the annular guide groove and the surface of the accommodating hole.

[0007] As a preferred solution, an annular groove is provided on the surface of the plug post, and retaining bars are fixedly connected to the four sides of the bottom of the annular guide groove, and the surface of the retaining bar is movably connected to the surface of the annular groove.

[0008] As a preferred solution, pin holes are provided at the lower ends of both sides of the inner cavity of the anchor rod.

[0009] As a preferred solution, a guide groove is provided at the middle end of the bottom of the adjusting column, and both ends of the bottom of the adjusting column are fixedly connected to fixed blocks, and the middle end of the fixed block is slidably connected to a push rod, and the two push rods are fixedly connected to a limiting pin block on one side away from each other, and the surface of the limiting pin block is slidably connected to the inner cavity of the anchor rod.

[0013] As a preferred solution, a reinforcing steel mesh is cast at the middle end of the vegetation concrete slab.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention can effectively reinforce the right side and slope surface of the slope through the arrangement of a concrete base and a vegetation concrete slab, thereby preventing the slope from collapsing due to the erosion of river water.

[0016] 2. The present invention forms a coordinated protection system with the vegetation concrete slab through the setting of the three-dimensional vegetation net, effectively reducing the probability of the soil and nutrient matrix filled in the porous structure of the vegetation concrete slab and the planted vegetation being washed away by rainwater, thereby further improving the effect of riverbank slope protection.

[0017] 3. The present invention effectively improves the strength of the connection between the slope and the vegetation concrete slab by setting the anchor rod, reduces the probability of collapse and landslide caused by water erosion, and enables personnel to install the metal frame and the three-dimensional vegetation net with the vegetation concrete slab by adjusting the setting of the screw, movable frame and limit rod, which brings great convenience to the construction work of personnel.

DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0027] Example 1:

[0028] See also Figures 1-6 As shown, the present invention provides a vegetated concrete structure for riverbank slope protection, including a slope body 1, a concrete base 2 is cast on the right side of the slope body 1, a vegetated concrete slab 3 is cast between the right end of the slope body 1 and the upper end of the left side of the concrete base 2, an anchor rod 7 is anchored between the surface of the vegetated concrete slab 3 and the right end of the slope body 1, a metal frame 8 is placed between the top of the anchor rod 7 and the top of the vegetated concrete slab 3, a three-dimensional vegetation net 9 is fixedly connected to the middle end of the metal frame 8, the bottom of the three-dimensional vegetation net 9 contacts the top of the vegetated concrete slab 3, the middle end of the top of the anchor rod 7 is movably connected to the adjusting screw 12 through a bearing, the middle end of the adjusting screw 12 is threadedly connected to a movable frame 13, both ends of the top of the movable frame 13 are fixedly connected to a limiting clamping rod 10, and the surface of the limiting clamping rod 10 is slidably connected to the top of the anchor rod 7.

[0029] In this technical solution, by setting up the concrete base 2 and the vegetation concrete slab 3, the right side and slope surface of the slope 1 can be effectively reinforced to prevent the slope 1 from collapsing due to the erosion of the river water. At the same time, because the vegetation concrete slab 3 is wrapped with ecological cementitious materials and aggregates, the internal porous structure can be filled with soil and nutrient matrix, providing growth space for plant roots, realizing vegetation coverage on the surface of the vegetation concrete slab 3, restoring the natural ecology of the river bank, and increasing the green space area. At the same time, the high porosity allows rainwater to penetrate quickly, reducing surface runoff and effectively alleviating waterlogging. Moreover, by setting up the three-dimensional vegetation net 9, a coordinated protection system can be formed with the vegetation concrete slab 3, effectively reducing the soil and nutrient matrix filled in the porous structure of the vegetation concrete slab 3. The embankment slope protection effect is further improved by the setting of the anchor rod 7. At the same time, the strength of the connection between the slope 1 and the vegetation concrete slab 3 is effectively improved, and the probability of collapse and landslide caused by water erosion is reduced. The movable frame 13 can be driven to move downward by operating the adjusting screw 12. The movement of the movable frame 13 can drive the limiting card rod 10 to move, so that the limiting card rod 10 can be tightly attached to the surface of the metal frame 8 around the three-dimensional vegetation net 9 during the movement, effectively avoiding the deviation of the metal frame 8 and the three-dimensional vegetation net 9, so that personnel can install the metal frame 8 and the three-dimensional vegetation net 9 between the vegetation concrete slab 3, which brings great convenience to the construction work of the personnel.

[0030] Example 2:

[0031] Based on the first embodiment, the present invention is as follows Figure 4 Figure 6As shown, it is disclosed that the middle end of the anchor rod 7 is provided with a receiving hole 21 around it, the bottom of the movable frame 13 is fixedly connected with an adjusting column 14, the surface of the adjusting column 14 is slidably connected to the inner cavity of the anchor rod 7, the surface of the adjusting column 14 is provided with an annular guide groove 15, the surface of the annular guide groove 15 and the surface of the receiving hole 21 are slidably connected with an insertion column 20, the surface of the insertion column 20 is provided with an annular groove 22, the bottom of the annular guide groove 15 is fixedly connected with a baffle 19 around it, and the surface of the baffle 19 is movably connected to the surface of the annular groove 22.

[0032] When the adjusting screw 12 is rotated, the movable frame 13 and the limiting clamping rod 10 are driven downward, so that the limiting clamping rod 10 can limit and fix the metal frame 8. At the same time, the movable frame 13 can push the adjusting column 14 to move downward along the inner cavity of the anchor rod 7 during the movement. The movement of the adjusting column 14 can drive the blocking bar 19 to disengage from the annular groove 22 on the plug column 20, so that the inclined surface of the annular guide groove 15 can contact the surface of the plug column 20, and push the plug column 20 along the surface of the receiving hole 21 along the inclined surface and insert it into the soil outside the anchor rod 7, thereby effectively improving the anti-pullout effect during the anchoring process between the anchor rod 7 and the slope 1, and reducing the probability of collapse of the vegetation concrete slab 3. Through the setting of the blocking bar 19 and the annular groove 22, the plug column 20 can be limited during the installation of the anchor rod 7, preventing the plug column 20 from extending out of the receiving hole 21 and affecting the installation of the anchor rod 7.

[0033] Example 3:

[0034] Based on the first embodiment, the present invention is as follows Figure 4-Figure 6 As shown, pin holes 17 are provided at the lower ends of both sides of the inner cavity of the anchor rod 7, a guide groove 23 is provided at the middle end of the bottom of the adjusting column 14, both ends of the bottom of the adjusting column 14 are fixedly connected to fixed blocks 18, the middle end of the fixed block 18 is slidably connected to a push rod 26, the side of the two push rods 26 away from each other is fixedly connected to the limiting pin block 16, the surface of the limiting pin block 16 is slidably connected to the inner cavity of the anchor rod 7, the side of the two push rods 26 approaching each other is fixedly connected to a movable disk 24, the upper end of the movable disk 24 is slidably connected to the surface of the guide groove 23, and a pressure spring 25 is fixedly connected between the sides of the two movable disks 24 approaching each other.

[0035] In the present technical solution, when the personnel manipulates the adjusting screw 12 to rotate and drive the movable frame 13 and the limiting card rod 10 to move downward, so that the limiting card rod 10 can limit and fix the metal frame 8, the movable frame 13 can push the adjusting column 14 to move downward along the inner cavity of the anchor rod 7 during the movement. The movement of the adjusting column 14 can drive the fixing block 18, the push rod 26 and the limiting pin block 16 to move downward, so that the limiting pin block 16 is at the side of the pin hole 17 under the action of the movement, and can be pushed by the pressure spring 25 which is pre-compressed and has tensioned. The movable plate 24, the push rod 26 and the limit pin block 16 are pushed to move, so that the limit pin block 16 can be inserted into the pin hole 17 under the action of movement, thereby limiting the vertical direction of the adjusting column 14, the movable frame 13 and the limit card rod 10, avoiding the subsequent rotation of the adjusting screw 12 due to external force and causing the adjusting column 14, the movable frame 13 and the limit card rod 10 to be displaced, ensuring the overall long-term stability of use. The setting of the guide groove 23 achieves the purpose of guiding the movable plate 24 and avoiding the movable plate 24 from rotating during the movement.

[0036] Example 4:

[0037] Based on the first embodiment, the present invention is as follows Figures 1-4 As shown, a concrete pavement 6 is cast between the top of the slope 1 and the left side of the vegetation concrete slab 3, a drainage groove 5 is opened at the middle end of the concrete pavement 6, a drainage pipe 4 is cast between the bottom of the concrete pavement 6 and the upper end of the concrete base 2, the middle end of the drainage pipe 4 is pre-buried in the upper end of the slope 1, a drainage grille is fixedly installed on the top of the concrete pavement 6 and above the drainage groove 5, and drainage holes are opened on the surface of the drainage grille, and clamping holes 11 are opened at both ends of the top of the outer surface of the anchor rod 7, and a reinforcing steel mesh 27 is cast at the middle end of the vegetation concrete slab 3.

[0038] In this technical solution, through the arrangement of the drainage trough 5, the drainage pipe 4 and the drainage grid plate, the accumulated water on the concrete pavement 6 can be discharged into the river channel in a centralized manner. Through the arrangement of the clamping hole 11, in the process of the limiting clamping rod 10 limiting and fixing the metal frame 8, one end of the limiting clamping rod 10 can be inserted into the clamping hole 11, thereby reducing the probability of the metal frame 8 loosening from the limiting clamping rod 10. By reinforcing the steel mesh 27, the crack resistance of the vegetation concrete slab 3 is effectively improved.
