Description
Technical Field
The invention belongs to the technical field of retaining walls, and particularly relates to a retaining wall reinforcing structure for large-volume filling.
Background
The retaining wall is a light retaining structure, and the anti-slip and anti-overturning properties of the retaining structure mainly depend on the self weight of the wall body and the gravity effect of filled soil bodies (including loads) above the wall bottom plate. At present, the retaining wall mainly has forms such as gravity type, anchor rod type, cantilever type, wall supporting type, empty box type and sheet pile type, and the like, and because the retaining wall adopts a reinforced concrete structure, the structure thickness of the retaining wall is reduced, the dead weight is lightened, the rigidity of a reinforced concrete bottom plate is improved, the height of a vertical arm of the retaining wall is higher, and the adaptability of the retaining wall under the condition of lower bearing capacity of a foundation is improved. However, the prior retaining wall is suitable for a slope with lower height, cannot be used for a high-fill slope, and cannot meet the safety technical index under the condition of meeting the economical efficiency. When the large-volume filled soil is treated by adopting single anchoring measures (such as a first prestressed anchor cable, a lattice anchor cable and the like), the strength of the bond between the filled soil and an anchoring body is low, the long first prestressed anchor cable with a large diameter is often required to reach design safety standards, the construction cost is high, the construction process is complex, and when the content of broken stones in the filled soil is high, the pore forming difficulty is high and the prestress is easy to lose. And if a large volume of soil body needs to be piled up, the wall body of the retaining wall needs to be lengthened and heightened, so that the condition can lead to serious engineering accidents caused by large dead weight of the wall body and cracking instability, and the wall body is easy to break in the middle part in the horizontal direction or the longitudinal direction.
