Self-adaptive anchoring device for deformed side slope and construction method of self-adaptive anchoring device

Abstract

The invention relates to the field of slope protection, and particularly discloses a self-adaptive anchoring device for a deformed slope and a construction method of the self-adaptive anchoring device. The self-adaptive anchoring device for the deformed side slope comprises a rotatable rotation adjusting disc of an fixing anchor rod, an anchor rod sleeve and a bottom rod. The self-adaptive anchoring device stably matches slope protection, the situations that the anchoring device falls off and the fixing capacity is reduced can be avoided, the fixing anchor rod is located inside a hole to form an arch through the arrangement of a stress strip, and therefore when the side wall of the anchoring device has bending stress, through the arch-shaped stress strip, the bending stress is distributed to the fixing anchor rod, so that the stress strength of the side wall of the fixing anchor rod is greatly reduced, a bending stress resistance strength of the fixing anchor rod is greatly improved, and the situation that a steel pipe pile is bent and deformed due to the fact that the steel pipe pile cannot resist acting force of slope expansion deformation is avoided.

Description

technical field [0001] The invention belongs to the technical field of road skins, in particular to slope protection technology, and specifically provides an adaptive anchoring device for deformed slopes and a construction method thereof. Background technique [0002] The side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. During the long-term use of the slope, due to the erosion of gravity and rain, the slope is prone to deformation, which will lead to the change of the slope structure, resulting in the collapse, fracture or soil erosion of the slope, resulting in roads or buildings being covered. [0003] In order to avoid this problem, it is usually necessary to construct an anchor device on the slope to fix the slope. At present, the commonly used anchoring treatment method is to install steel pipe piles at intervals along the uphill side edge of the deformed slope on the periphery of the deformed ...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned anchoring device, the contact with the slope protection is only fixed by the friction force between the outer wall of the anchor rod and the hole wall, which leads to unstable fixing of the anchoring device and the slope protection, and extrusion causes the anchoring device to fall off or reduce the fixing capacity. With the straight rod structure, steel pipe piles are prone to bending deformation due to the force that cannot resist the expansion and deformation of the slope
