Anchoring device, prestress anchoring structure and construction method of prestress anchoring structure

Abstract

The invention discloses an anchoring device, a prestress anchoring structure and a construction method of the prestress anchoring structure. The anchoring device comprises a first anchor plate and a second anchor plate, the first anchor plate and the second anchor plate are both provided with via holes allowing prestressed tendons to penetrate therethrough, elastic pieces are arranged between the first anchor plate and the second anchor plate and provided with bent structures bent in the first direction, the two ends of the elastic pieces are fixedly connected with the first anchor plate and the second anchor plate respectively, the anchoring device further comprises a fastening assembly, the fastening assembly comprises first bolts and first fastening nuts, the first bolts penetrate through the first anchor plate and the second anchor plate, and the first fastening nuts are in threaded connection with the parts, penetrating out of the first anchor plate and the second anchor plate, of the first bolts. According to the anchoring device, the elastic pieces are arranged between the two anchor plates, so that the anchoring device can generate elastic deformation under stress, and when the anchoring device is applied to the prestress anchoring structure, the anchoring device generates elastic deformation under earthquake power reciprocating impact to play a role in resisting earthquakes, and the possibility of disasters such as collapse and landslide is reduced.

Description

technical field [0001] The invention relates to the technical field of prestressed anchoring, in particular to an anchoring device, a prestressed anchoring structure and a construction method thereof. Background technique [0002] Earthquakes have always been an important source of power for geological disasters, causing collapses, landslides and other disasters. Prestressed anchor cables are an important prevention and control technology for strengthening potential collapsed bodies. However, for large-scale potential collapses, using the traditional rigid anchor cable support method to resist the impact of seismic dynamic loads requires a very large support structure and strong anchorage, which is costly and often due to the randomness of seismic dynamics. Insufficient predictions of the ground faults lead to difficulties in the design of the prevention and control structures and anchor cables, as well as the failure of the support structures and the occurrence of landslid...
