Description

Technical Field

[0001] This utility model relates to the field of slope protection, and in particular to a slope protection structure. Background Technology

[0002] A column-slab retaining wall structure with unloading plates consists of a base, columns, bottom beams, tie rods, and baffles. It balances the entire wall by utilizing the weight of the soil on the unloading plates. Its advantages include less foundation excavation compared to cantilever retaining walls, prefabrication, and rapid construction. However, its disadvantages include the tendency for the prefabricated, overlapping unloading plates to shift under earth pressure during subsequent backfilling, creating large gaps between the plates. This allows backfill to escape through these gaps, potentially leading to insufficient soil weight on the unloading plates over time, thus affecting the stability of the slope support. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slope support structure that helps prevent the unloading plate from sliding under the action of earth pressure and helps prevent soil loss, thereby improving the stability of the slope support.

[0004] To solve the above problems, a slope protection structure was adopted, which includes:

[0005] The column is provided with multiple columns spaced apart, and the upper part of the column is provided with a horizontal bracket. The bracket is provided with a first protrusion that is perpendicular to the side of the column.

[0006] Retaining wall panels, which are installed between the columns;

[0007] The bottom beam has one end set on the corbel and the other end set in the backfill. The bottom surface of the bottom beam has a bottom beam groove that is fitted onto the first protruding strip, and a second protruding strip is set on it to form a first step surface and a second step surface that are spaced apart.

[0008] The tie rod has one end fixed to the column and the other end fixed to the cantilever end of the bottom beam.

[0009] The secondary beam is erected on the second step surface;

[0010] The unloading plate has a T-shaped cross section, with its edge placed on the first step surface and its lower part placed on the secondary beam.

[0011] With this structure, the groove in the bottom beam helps prevent the cantilever bottom beam from shifting left and right. The tie rod connects the cantilever end of the bottom beam to the column. The secondary beam is placed on the second step surface to support it under the unloading plate, which helps resist the bending deformation of the unloading plate. The first step surface supports the edge of the T-shaped unloading plate, which helps prevent the unloading plate from shifting left and right.

[0012] As a further improvement of this utility model, a first oblique straight threaded sleeve is pre-embedded on the column, and the first straight threaded sleeve is welded to the steel reinforcement skeleton inside the column. A first elongated hole is opened on the retaining wall plate for the first straight threaded sleeve to pass through. A second oblique straight threaded sleeve is pre-embedded on the bottom beam, and the second straight threaded sleeve is welded to the steel reinforcement skeleton inside the beam. The tie rod is extended by a third straight threaded sleeve, with its upper end threadedly connected to the first straight threaded sleeve and its lower end connected to the second straight threaded sleeve. A second elongated hole is opened on the unloading plate for the second straight threaded sleeve to pass through.

[0013] With this structure, the tie rod is easy to install, and the threaded connection is achieved through a straight threaded sleeve, which facilitates the adjustment of tightness and helps to stabilize the bottom beam.

[0014] As a further improvement of this utility model, the cantilever end of the bottom beam is T-shaped.

[0015] With this structure, the T-shaped end integrates better with the backfill, resulting in a stronger bond.

[0016] As a further improvement of this utility model, a secondary beam groove is provided on the side of the end of the secondary beam, and a rib beam is adapted to be connected thereto, with the rib beam being disposed on the second step surface.

[0017] This structure prevents the secondary beams from shifting, thus providing stable support for the unloading plate.

[0018] This invention can use more prefabricated components, which facilitates assembly, helps prevent the unloading plate from sliding under the action of earth pressure, and helps prevent soil loss, thereby improving the stability of slope support. Attached Figure Description

[0036] Retaining wall panel 2, which is installed between columns 1;

[0037] The bottom beam 3 has one end set on the corbel 101 and the other end set in the backfill 11. The bottom surface of the bottom beam 3 is provided with a bottom beam groove 301 and fitted on the first protrusion 102. A second protrusion 302 is provided on it to form a first step surface 303 and a second step surface 304 that are spaced apart.

[0039] Secondary beam 5 is erected on the second step surface 304;

[0040] The unloading plate 6 has a T-shaped cross section, with its edge placed on the first step surface 303 and its lower part placed on the secondary beam 5.

[0041] With this structure, the groove 301 of the bottom beam helps to prevent the cantilever bottom beam 3 from shifting left and right. The tie rod 4 connects the cantilever end of the bottom beam 3 to the column 1. The secondary beam 5 is placed on the second step surface 304 to support it under the unloading plate 6, which helps to resist the bending deformation of the unloading plate. The first step surface 303 supports the edge of the T-shaped section unloading plate 6, which helps to prevent the unloading plate 6 from shifting left and right.

[0042] In this embodiment, a first oblique straight threaded sleeve 7 is pre-embedded on the column 1, and the first straight threaded sleeve 7 is welded to the steel reinforcement skeleton inside the column.

[0044] In this embodiment, the cantilever end of the bottom beam 3 is T-shaped.

[0045] With this structure, the T-shaped end integrates better with the backfill, resulting in a stronger bond.
