[0037] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3 , the anchor assembly 300 comprises a first anchor 310, a connecting piece 320 and a second anchor 330 connected in sequence. The first anchor 310 is anchored on the slope 600, and the second anchor 330 is connected with the concrete retaining wall 100.

The first anchor 310 is exposed from the side of the concrete retaining wall 100 close to the slope 600, and the other side of the concrete retaining wall 100 is a smooth surface, which is aesthetically pleasing.
[0038] In some embodiments, referring to Figure 1 、 Figure 2 and Figure 3The connecting piece 320 comprises a first connecting plate 321, a second connecting plate 322 and a connecting rod 323. The first connecting plate 321 and the second connecting plate 322 are arranged at intervals, and the first connecting plate 321 and the second connecting plate 322 are connected by the connecting rod 323. The first connecting plate 321 is provided with a first connecting hole, and the first anchor 310 is arranged in the first connecting hole. The second connecting plate 322 is provided with a second connecting hole, and the second anchor 330 is arranged in the second connecting hole. The first connecting plate 321 is detachably connected with the first anchor 310, and the second connecting plate 322 is detachably connected with the second anchor 330. The connecting rod 323 is provided with two, and the two connecting rods 323 are respectively connected at both ends of the first connecting plate 321 and the second connecting plate 322. After the first anchor 310 is arranged in the first connecting hole, the first anchor 310 is connected with the first connecting plate 321. After the second anchor 330 is arranged in the second connecting hole, the second anchor 330 is connected with the second connecting plate 322. The first anchor 310, the second anchor 330 and the connecting piece 320 are convenient to disassemble and assemble.
[0039] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the first connecting plate 321 is provided with a first connecting hole, and the second connecting plate 322 is provided with a second connecting hole. The end of the first anchor 310 connected with the connecting piece 320 is provided with a first threaded part 311, the first threaded part 311 is arranged in the first connecting hole, and the first threaded part 311 is connected with a nut. The end of the second anchor 330 connected with the connecting piece 320 is provided with a second threaded part 331, the second threaded part 331 is arranged in the second connecting hole, and the second threaded part 331 is connected with a nut. After the first anchor 310 passes through the first connecting hole and is locked by the nut, the length of the first threaded part 311 extending out of the first connecting hole can be adjusted by rotating the nut. After the second anchor 330 passes through the second connecting hole and is locked by the nut, the length of the second threaded part 331 extending out of the second connecting hole can be adjusted by rotating the nut. The connecting piece 320 cooperates with the nut to tighten the first anchor 310 and the second anchor 330, so as to stabilize the pulling force of the anchoring assembly 300 on the concrete retaining wall 100.
[0040] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the length direction of the anchoring assembly 300 is inclined to the vertical direction. The anchoring assembly 300 is arranged obliquely, the lower end of the anchoring assembly 300 is anchored on the slope 600, and the upper end is in tension with the concrete retaining wall 100, so as to improve the efficiency of the whole slope 600 supporting structure.
[0041] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3The concrete retaining wall 100 includes a concrete layer 110 and a steel reinforcement cage 120. The concrete layer 110 is wrapped around the outside of the steel reinforcement cage 120, which is connected to the anchoring assembly 300. During construction, the second anchor 330 is first connected to the steel reinforcement cage 120, and then the concrete is poured around the steel reinforcement cage 120 to ensure structural stability.
[0042] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the concrete retaining wall 100 is connected to a plurality of bored piles 130 at the bottom. The bored piles 130 penetrate deep into the ground, providing a large lateral friction and end resistance. When the gravity retaining wall is subjected to lateral forces such as soil pressure and water pressure, these piles can resist the overturning moment of the retaining wall around the base surface, thereby significantly improving the anti-overturning stability of the retaining wall.
[0043] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , a grass cover is laid on the fill layer 400. The root system of the grass cover can penetrate deep into the soil, forming a dense network structure that effectively fixes soil particles and prevents soil loss under the action of rainwater erosion and wind.
[0044] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the composite fill slope 600 retaining structure further includes a drainage pipe 500 that passes through the concrete retaining wall 100 and the stone layer 200, and is located below the concrete retaining wall 100. Through the arrangement of the drainage pipe 500, underground water inside the slope 600 can be effectively discharged, reducing the water pressure inside the slope 600. Groundwater pressure is one of the important factors for the instability of the slope 600. When the water pressure is too high, it may cause the soil of the slope 600 to soften and the shear strength to decrease, thereby triggering the sliding or collapse of the slope 600.
[0045] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the drainage pipe 500 is connected to a filter assembly at one end near the slope 600. The filter assembly includes geotextile and gravel blocks. When water flows through the drainage pipe 500, the geotextile can intercept soil particles, fine sand, small stones and other impurities in the water, preventing these impurities from clogging the drainage pipe 500 and ensuring the smoothness of the drainage pipe 500. There are certain gaps between the gravel blocks, which can allow water to flow through, enhancing the drainage effect. At the same time, the air permeability of the gravel blocks also helps to keep the drainage pipe 500 dry, preventing corrosion caused by moisture.
[0046] In the description of the present specification, the description referring to the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily mean the same embodiment or example. Furthermore, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
[0047] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made thereto without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
