Technical Field

The invention belongs to the technical field of road kerbs, particularly relates to a slope protection technology, and particularly provides a self-adaptive anchoring device for a deformed slope and a construction method thereof.

Background

The side slope refers to a slope surface with a certain slope which is formed on two sides of the roadbed to ensure the stability of the roadbed. In the long-term use process of the side slope, the side slope is easy to deform due to the fact that the side slope is washed by gravity and rainwater, the structure of the side slope is changed, the side slope collapses, breaks or loses water and soil, and a road or a building is covered.

In order to avoid the problem, an anchoring device is usually required to be constructed on the side slope for fixing the side slope, and an currently adopted anchoring treatment mode is to arrange steel pipe piles at intervals along the side edge of the upper slope of the deformed side slope at the periphery of the deformed side slope for reinforcement treatment so as to prevent the upper side slope from further deforming and expanding. The steel pipe pile has the characteristics of rapidness, simple and effective construction conditions and the like; however, the sectional area of the steel pipe is small, and the actual bending resistance of the steel pipe is weak, so that the actual reinforcing effect on the side slope is limited, and the problem that the steel pipe pile cannot resist the acting force of the side slope expansion deformation in some cases, so that the steel pipe pile is bent and deformed, and even the anchoring device is completely failed easily occurs. For example, chinese application publication No. CN109469076 proposes an anchoring device for a deformed slope, which is used to solve the problems that the bending resistance of a steel pipe pile is weak, the reinforcing effect on the slope is limited, and the bending deformation of the steel pipe pile is likely to occur, and even the anchoring device fails completely. The steel pipe pile is connected with the anchoring piece through the connecting piece by arranging the anchoring piece and the connecting piece, and the steel pipe pile is provided with tension support through the anchoring effect of the anchoring piece; and then one end of each steel pipe pile inserted into the side slope can be connected with the stable bedrock, and the end part of each steel pipe pile penetrating out of the surface of the side slope is connected with the anchoring part through the connecting part, so that the bending resistance of the steel pipe pile is improved, and the further deformation problem of the side slope is effectively controlled.

However, the contact position between the anchoring device and the slope protection is only fixed by the friction force between the outer side wall of the anchor rod and the wall of the hole, so that the anchoring device and the slope protection are unstable in fixation, the anchoring device falls off or the fixing capacity is reduced due to extrusion, meanwhile, the existing anchoring devices are all of a straight rod structure, and the steel pipe pile is easy to bend and deform due to the fact that the acting force which cannot resist the expansion and deformation of the slope occurs.
