Description

Technical Field

[0001] The utility model relates to the field of slope support structures, in particular to a bite pile foundation protection under asymmetric force. Background Art

[0002] In the prior art, in order to set up a support structure on the slope of strongly weathered siltstone, deep piles are generally used, and prestressed anchor cables need to be set up for auxiliary support. The defects of this are obvious. First, a construction site needs to be dug out on the side of the deep pile close to the lower slope, which requires a large amount of excavation and high cost. Then, due to the deep piles, more prestressed anchor cables need to be set up. Finally, another important point is that backfill soil is required after the deep piles are laid. Such backfill soil will affect the overall seismic performance of the support structure. Therefore, the defects of the above-mentioned support structure are very obvious and need to be improved.
