Problems solved by technology

In the construction of the traditional prestressed anchor cable sash beam, due to the non-perpendicular relationship between the anchor cable and the surface of the sash beam, the tension of the anchor cable is non-linear when stretched, and there is a knuckle on the surface of the sash beam, which makes the anchor The front part of the cable is upturned, so although the tensioning machine shows that the tension is in place, the actual tension stress in the slope anchor cable is difficult to achieve the design effect and cannot meet the design requirements

Embodiment

[0028] Such as Figure 1-Figure 3 , a slope support structure, comprising a prestressed anchor cable 1 and a sash beam 2 arranged on the slope surface, a pedestal 3 is arranged on the surface of the intersection of the sash beam 2, and a spiral bar is embedded in the pedestal 3 4. One end of the spiral rib 4 extends to the sash beam 2 and connects with the steel skeleton of the sash beam 2 , and the other end of the spiral rib 4 is embedded in the pedestal 3 . The prestressed anchor cable 1 vertically passes through the spiral reinforcement 4 and the pedestal 3, and the pedestal 3 is located around the spiral reinforcement 4. There is also an encrypted steel skeleton 5, and one end of the encrypted steel skeleton 5 extends into the frame beam 2 and connects with the frame beam 2. steel frame connections.

[0029] Further, the pedestal 3 is a wedge-shaped body with an inclined upper surface, and the inclination angle of the inclined surface of the pedestal 3 relative to the in...

Abstract

The invention discloses a slope supporting structure and method and belongs to the technical field of slope supporting engineering. The slope supporting structure comprises pre-stressed anchor cables and frame beams arranged on a slope surface, wherein pedestals are arranged on the surfaces of cross positions of the frame beams, spiral ribs are embedded into the pedestals, one end of each spiral rib extends to the corresponding frame beam to be connected with a steel bar framework of the frame beam, and the other end of the spiral rib is embedded into the corresponding pedestal. The pre-stressed anchor cables vertically penetrate through the spiral ribs and the pedestals, and density-increased steel bar frameworks are also arranged around the spiral ribs in the pedestals and extend to the frame beams to be connected with the steel bar frameworks of the frame beams. The surfaces of the pedestals and the pre-stressed anchor cables form vertical angles, it is ensured that the pre-stressed anchor cables are kept linear in the tensioning process, a tensile stress meets the design requirements, and finally the slope supporting structure is reinforced and is better in slope supporting effect.

Description

technical field [0001] The invention relates to the technical field of slope support engineering, in particular to a slope support structure and a support method. Background technique [0002] With the continuous expansion of the field of slope support engineering, the application of prestressed anchor cable frame beams is becoming more and more extensive. In the construction of the traditional prestressed anchor cable sash beam, due to the non-perpendicular relationship between the anchor cable and the surface of the sash beam, the tension of the anchor cable is non-linear when stretched, and there is a knuckle on the surface of the sash beam, which makes the anchor The front part of the cable is upturned, so although the tensioning machine shows that the tension is in place, the actual tension stress in the slope anchor cable is difficult to achieve the design effect and cannot meet the design requirements. Contents of the invention [0003] In view of the above problem...
