[0002] In recent years, due to frequent extreme weather, large-scale floods have occurred throughout the country during the flood season, seriously affecting the levee structures on both sides of the river and the safety of people's lives and property. In order to ensure the stability of the levee structure, normal flow of the river during the flood season, and reduce the scouring of the levee structures on both sides by floods, mortar masonry, wire mesh gabions, riprap and other methods are usually used to protect the levees during the construction of water conservancy projects.

[0003] The prior art also discloses a plain river channel bayonet dike and its construction method, such as patent number CN112761107A, which includes a dike body, two mutually parallel limit grooves are symmetrically arranged on the top surface of the dike body, a water retaining mechanism is arranged in the limit groove, and dike corner reinforcement mechanisms and slope reinforcement mechanisms are symmetrically arranged on both sides of the dike body, the slope reinforcement mechanism is located above the dike corner reinforcement mechanism, and an expansion water stop strip is arranged between the slope reinforcement mechanism and the dike corner reinforcement mechanism. The dike corner reinforcement mechanism includes a vertical reinforcement plate and an inclined reinforcement plate, the inclined reinforcement plate is fixedly connected to the top of the vertical reinforcement plate, and anchor holes are evenly arranged on the vertical reinforcement plate. Through the design of the vertical reinforcement plate and the inclined reinforcement plate, the entire dike corner can be wrapped, reducing the scouring of the dike body and the dike corner by water flow, reducing soil erosion, and improving the reliability of the entire dike body. The anchor holes facilitate the fixed connection between the vertical reinforcement plate and the dike body through anchor rods.

[0029] Embodiment 1

[0030] Reference Figure 1 The utility model discloses a river embankment reinforcement structure, which includes a reinforcement cavity 2 excavated below the embankment body 1, and a reinforcement layer 3 is stacked in the reinforcement cavity 2. Specifically, a plant layer is planted above the embankment body 1, and a reinforcement cavity 2 is excavated at the bottom of the embankment body 1. Then, the reinforcement layer 3 is stacked in the reinforcement cavity 2 and backfilled. One side of the reinforcement layer 3 is connected to the river channel as a reinforcement for the embankment foot. It can also be applied to embankment foot, embankment slope, river bottom and other parts;

[0031] Specifically, refer to Figure 2-Figure 3 The reinforcement layer 3 includes a plurality of hexahedral blocks 4. In the present embodiment, the hexahedral blocks 4 are prefabricated concrete hexahedrons. The hexahedral blocks 4 are cubes with isosceles trapezoidal cross sections. The stacked hexahedral blocks 4 are inclined toward the river channel. The top surface structural dimensions of the hexahedral blocks 4 are 1000mm*500mm, the bottom surface structural dimensions are 1000mm*1000mm, and the height is 700mm; the angle between the top surface and the side surface is 110°, and the angle between the bottom surface and the side surface is 70°.

[0032] The four sides of the hexahedral block 4 are provided with first reserved holes 5 which are interconnected. The first reserved holes 5 are D40mm reserved holes which are arranged 350mm away from the bottom of the hexahedral block 4 and are used for connecting and fixing a plurality of hexahedral blocks 4 .

[0033] Each hexahedral block 4 is stacked in multiple layers in reverse order along the direction perpendicular to the water flow, and is stacked tightly during hoisting. The first reserved holes 5 of multiple hexahedral blocks 4 along the direction perpendicular to the water flow are horizontally connected by first steel bars 6, and second steel bars 7 are used to connect the first reserved holes 5 longitudinally every 3m along the water flow direction. The ends of multiple first steel bars 6 passing through the first reserved holes 5 and the ends of multiple second steel bars 7 passing through the first reserved holes 5 are connected by third steel bars 8. Among them, the first steel bars 6 and the second steel bars 7 are both φ10 smooth steel bars, and the third steel bars 8 are φ20 steel bars.

[0034] The first steel bar 6, the second steel bar 7 and the third steel bar 8 connect the multiple hexahedral blocks 4 perpendicular to the water flow direction and along the water flow direction to form a whole, which has good integrity and can effectively resist the scouring of the embankment structures on both sides by excessive floods, and play a role in reinforcing the embankment structure.

[0035] Embodiment 2

[0036] Reference Figure 3 and Figure 4 Based on the same concept as the first embodiment, the four sides of the hexahedral block 4 of the river embankment reinforcement structure are provided with interconnected second reserved holes 9; wherein the second reserved hole 9 is a D40mm reserved hole set 150mm away from the bottom of the hexahedral block 4, for use in hoisting and transportation of the hexahedral block 4. PVC pipes 15 are evenly pre-buried inside the first reserved hole 5 and the second reserved hole 9, and the setting of the PVC pipe 15 can prevent the concrete hexahedral block 4 from being damaged when the hexahedral block 4 is hoisted or connected with steel bars.

[0037] A third reserved hole 10 is formed on the top surface of the hexahedral block 4, and a lifting ring 11 is embedded in the hexahedral block 4 and located in the third reserved hole 10 for later lifting and stacking. The third reserved hole 10 is a reserved hole with a D of 150 mm and a depth of 100 mm.

[0038] Among them, refer to Figure 5 In this embodiment, the lifting ring 11 adopts φ14 steel bars and is in an inverted T shape as a whole. Specifically, the lifting ring 11 includes an inverted U-shaped central portion 12 located in the third reserved hole 10, and also includes bending portions 13 on both sides of the hexahedral block 4. The two ends of the central portion 12 are integrally connected to the bending portions 13 on both sides through connecting portions 14; the total horizontal length of the lifting ring 11 is 600mm, the total longitudinal length is 210mm, and the length of the bending portion 13 is 60mm.

[0039] Working principle: Use the lifting ring 11 in the third reserved hole 10 on the hexahedron block 4 to stack each precast concrete hexahedron block 4 in a positive and negative order in the direction perpendicular to the water flow. Stack them tightly during hoisting. Use the first steel bar 6 of φ10 to connect horizontally through the first reserved hole 5. Use the third steel bar 8 of φ20 at both ends to weld with the first steel bar 6 to form a whole hexahedron block 4.

[0040] Precast concrete hexahedrons are longitudinally connected by second steel bars 7 of φ10 every 3m along the water flow direction using first reserved holes 5, and third steel bars 8 of φ20 are welded to the second steel bars 7 at both ends to form a whole hexahedron.

[0041] The precast concrete hexahedrons are stacked in three layers in height direction and connected to form a whole in the direction perpendicular to and along the water flow. The omnidirectional displacement of the embankment is limited by a supporting whole formed by the hexahedral blocks 4, and no collapse will occur. The embankment can be used as a reinforced anti-scouring structure to ensure the safety of the embankment during flood seasons.

[0042] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
