Problems solved by technology
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 prediction of the prediction results in difficulties in the design of prevention and control structures and anchor cables, as well as the failure of support structures and the occurrence of collapse and landslides

Embodiment Construction
[0047] The present invention is described below based on the embodiments, and those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
[0048] Unless the context clearly requires otherwise, throughout the specification and claims, words such as "including", "comprising" and the like should be construed in an inclusive rather than an exclusive or exhaustive sense; that is, "including but not limited to" meaning.
[0049] In view of the existing traditional rigid anchor cable support methods, which require very large supporting structures and strong anchoring for large potential collapse bodies, high cost and easy failure, some improved solutions are proposed, such as A retractable lock device is formed by sleeve sliding and spring action in the anchor hole, which can make the anchor cable adapt to the deformation of the surrounding rock to a certain extent and consume a part of ...

The invention discloses an anchoring device, a prestressed anchoring structure and a construction method thereof. The anchoring device includes a first anchor plate and a second anchor plate, the first anchor plate and the second anchor plate are both provided with through holes for the prestressed tendons to pass through, and an elastic member is arranged between the first anchor plate and the second anchor plate , the elastic member has a curved structure bent in the first direction, and the two ends of the elastic member are respectively fixedly connected with the first anchor plate and the second anchor plate; it also includes a fastening assembly, including a first bolt and a first fastening nut, the second A bolt passes through the first anchor plate and the second anchor plate, and the first fastening nut is threadedly connected with the part where the first bolt passes through the first anchor plate and the second anchor plate. An elastic member is set between the two anchor plates so that the anchoring device can produce elastic deformation when it is stressed. When it is applied to a prestressed anchorage structure, under the reciprocating impact of seismic force, the anchoring device will produce elastic deformation to resist earthquakes. The role of reducing the possibility of disasters such as collapses and landslides.
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, which will bring disasters such as collapses and landslides. Prestressed anchor cable is an important prevention and control technology for strengthening potential collapse bodies. However, for a potentially large collapsed body, the traditional rigid anchor cable support method is used to resist the impact of seismic dynamic loads, which requires a very large supporting structure and strong anchoring, and the cost is high, and it is often due to the randomness of seismic dynamics. Insufficient prediction, which leads to difficulties in the design of prevention and control structures and anchor cables, as well as the failure of supporting structures and the occurre...
