Description

TECHNICAL FIELD

[0001] The application relates to the technical field of rock-soil slope support design, in particular to a rock-soil slope support structure and a construction method. BACKGROUND

[0002] The rock-soil slope can be divided into natural rock-soil slope and artificial rock-soil slope according to its cause. The natural rock-soil slope refers to the natural mountain slope and the bank slope of rivers, lakes and seas. The artificial rock-soil slope refers to the rock-soil slope formed by excavating foundation pits, foundation trenches, road cuts or filling embankments and earth dams. Under the action of gravity, water pressure, vibration force and other external forces, the rock-soil slope often slides or collapses, and the damage of the rock-soil slope can cause traffic interruption, building collapse, river blockage and reservoir siltation, which brings great loss to people's life and property.

[0003] The related technology discloses a rock-soil slope support anti-slide pile structure in Chinese patent CN214033755U. The structure is composed of a lower slope protection inclined table, an upper slope protection inclined table, an anchor cable, an anti-slide pile, an adjusting cylinder, a lower limiting groove, an avoiding groove, a filling cavity and an upper limiting inclined groove. One side of the lower slope protection inclined table is placed on one end of the anti-slide pile and located on one side of the anti-slide pile. A plurality of lower limiting grooves are formed on the lower slope protection inclined table. One side of the upper slope protection inclined table is placed on one end of the anti-slide pile and located on the other side of the anti-slide pile. The other side of the upper slope protection inclined table extends away from the anti-slide pile. A plurality of upper limiting inclined grooves are formed on the upper slope protection inclined table. The upper limiting inclined grooves and the lower limiting grooves correspond to each other. An avoiding groove is formed on one end of the anti-slide pile and located between the upper slope protection inclined table and the lower slope protection inclined table. The adjusting cylinder is correspondingly arranged in the avoiding groove. One end of the anchor cable is arranged in the lower limiting groove. The other end of the anchor cable extends away from the other end of the anti-slide pile in a diagonal direction after sequentially penetrating through the adjusting cylinder and the upper limiting inclined groove. The lower limiting groove, the upper limiting inclined groove and the avoiding groove cooperatively form the filling cavity.

[0004] In the above related technology, the upper end of the anti-slide pile is fixed by the anchor cable, the lower end of the anti-slide pile is buried in the rock-soil slope, and one side of the anti-slide pile abuts against the earthwork of the rock-soil slope, so as to achieve the supporting effect. The anti-slide pile mainly relies on the anchor cable to maintain stability, and the pressure on the anchor cable is large. When the rock-soil slope slides, the collapsed earthwork will impact the upper end of the anti-slide pile, which may affect the service life and safety of the anchor cable. Therefore, it needs to be improved. SUMMARY
