Benefits of technology

This patented technology describes an improved design for suspended structures used in road works or other applications where they may experience sudden changes caused by heavy loads such as vehicles passing over it without causing excess strain or damaging equipment. These temporary modifications have been made at various locations along their length, including edges near the ends of the main part of each component's mountings. By placing these components within the upside down position, there is no longer any danger from being hit accidentally due to gravity forces acting upon this arrangement. Additionally, the use of anchor ropes prevents movement even when subjected to lateral loadings while maintaining stability. Overall, this new technical solution improves the overall performance and durability of the protected structure.

Problems solved by technology

This technical problem addressed by this patents relates to controlling slopings that may lead to accidents when they happen on an inclined surface with strong windstorm activity. Existing methods either require expensive equipment or involve dangerous procedures like excavation. Therefore, it would benefit from developing new ways to prevent these issues without adding extra costs or causing other risks associated with existing solutions.

Embodiment 1

[0028] Such as figure 1 and figure 2 As shown, the protection structure of a slope overhang body in the present invention includes anchor rods 5 vertically arranged on both sides of the overhang body 2 and penetrating into the parent rock mass 1, and the anchor rods 5 on both sides are located outside the parent rock mass 1. There are steel strands 4 connected between the exposed sections, and the steel strands 4 are tightened and tightly fitted along the outer wall of the waist of the inverted body 2. A belt-ring steel bar 6 is also arranged between adjacent steel strands 4, and also includes The concrete support pier 11 in the cavity 3 of the parent rock mass below the body 2, the inner side of the slope of the cavity 3 of the parent rock mass is equipped with an in-slope anchor 8, the bottom of the cavity 3 of the parent rock mass is equipped with a base anchor 9, and the in-slope anchor 8 and the exposed section of the base anchor rod 9 are all connected to the steel str...

Embodiment 2

[0037] A method for the protection and management of a slope overhang, comprising the following steps: (1) determining anchor hole positions on both sides of the waist of the overhang, installing the anchor, the anchorage section of the anchor passing through the strong unloading boundary line to a certain depth, and the exposed section Reserve enough length to connect with the steel strands. After the construction of the anchors is completed, a tension test should be carried out to ensure that the anchors are installed qualified; The two ends of the steel bars with rings are respectively inserted into two adjacent steel strands; the other end of each steel strand is temporarily fixed with the anchor rods corresponding to the other side of the upside-down body, and the steel strands and the ringed steel bars are adjusted in the upside-down suspension. The position of the waist of the body, by adjusting the steel strands to the best stress-bearing position, and limiting the dist...

Abstract

The invention discloses a protective structure and a treatment method for a side slope overhang body. The protective structure comprises anchor rods arranged on the two sides of the overhang body andpenetrating into a parent rock body, steel strands are connected between the exposed sections, outside the parent rock body, of the two-side anchor rods, the steel strand are tightened and closely fitted along the waist outer wall of the overhang body, ringed steel bars are further arranged between the adjacent steel strands, a concrete supporting pier arranged in a cavity of the parent rock bodyunder the overhang body is further included, a slope inner anchor rod is installed on the inner side of a cavity slope of the parent rock body, a substrate anchor rod is installed at the bottom of thecavity of the parent rock body, and the exposed sections of the slope inner anchor rod and the substrate anchor rod are correspondingly connected with steel bars in the concrete supporting pier. According to the protective structure for the side slop overhang body, the anchor rods are arranged on the two sides of the overhang body, the waist of the overhang body is fixed by the steel strands, theconcrete supporting pier is arranged under the overhang body to support the overhang body, vibration damage to the overhang body cannot be produced, the effects of strengthening the overhang body andpreventing the further deformation of the overhang body are achieved, the construction safety risk is small, and the treatment effect on the overhang body is good.
