Embodiment 1
[0057] On the basis of the above embodiments, further, a steep slope embankment retaining structure mainly includes a double-row pile bearing cantilever anchor cable retaining wall, including a pile foundation, a cantilever retaining wall 1 and a prestressed anchor cable 3 . The cantilever retaining wall 1 is composed of a base plate 12 and a vertical wall 11 arranged above the base plate 12, wherein the base plate 12 is made in cooperation with the pile cap. Below the cantilever retaining wall 1, two rows of foundation piles 2 are arranged at intervals along its length direction. Both the cantilever retaining wall 1 and the pile foundation are reinforced concrete structures, and the cantilever retaining wall 1 is rigidly connected to the top of the pile foundation.
[0058] Two rows of prestressed anchor cables 3 are arranged on the vertical wall 11 of the cantilever retaining wall 1 , and the anchor sections of the anchor cables 3 are placed in the stable soil layer or bedroc...
Embodiment 2
[0069] This embodiment is basically the same as Embodiment 1. For the sake of brevity, in the description process of this embodiment, the same technical features as Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be described:
[0070]A retaining structure for a steep slope embankment mainly includes an anchor-pull pile bearing cantilever anchor cable retaining wall, including a pile foundation, a cantilever retaining wall 1 , a prestressed anchor cable 3 and a prestressed anchor rod 6 . Under the cantilever retaining wall 1, foundation piles 2 and prestressed anchor rods 6 are arranged at intervals along its length direction. A row of foundation columns 2 is arranged on the outer side of the bottom plate 12 , and a row of anchor rods 6 is arranged on the inner side of the bottom plate 12 .
[0071] The specific implementation of the support structure includes: excavating the pile foundation construction platform on th...
