Dispersed anchoring device and dispersed anchoring method suitable for large-tonnage FRP inhaul cable

Abstract

The invention discloses a dispersed anchoring device and a dispersed anchoring method suitable for a large-tonnage FRP inhaul cable. The dispersed anchoring device comprises an inner conical sleeve, asmall end cover plate located at a small end of the inner conical sleeve and a large end cover plate located at a large end of the inner conical sleeve. The small end cover plate is a first yarn splitting plate, the large end cover plate is a second yarn splitting plate, and at least one third yarn splitting plate is further arranged in the inner conical sleeve; rib holes distributed according toa first rule are formed in the first yarn splitting plate. The rib holes distributed according to a second rule are formed in the second yarn splitting plate. The rib holes distributed according to athird rule are formed in the third yarn splitting plate. A core of the anchoring device lies in overall bending and local splitting of the FRP inhaul cable in an anchorage area, creep deformation ofthe FRP inhaul cable under long-term load holding can be remarkably reduced, the FRP inhaul cable is prevented from being pulled out and damaged, meanwhile, a size of an anchorage device can be reduced, and manufacturing cost can be decreased.

Description

technical field [0001] The invention relates to a large-tonnage FRP cable decentralized anchoring technology utilizing FRP cable overall bending and partial splitting, and belongs to the technical field of large-tonnage FRP cable anchoring. Background technique [0002] Bridges are key hubs in road networks and play a vital role in transportation. With the development of society and economy, the demand for sea-crossing bridges and long-span bridges crossing valleys has further increased. With the development of modern bridge technology, cable-supported bridges have become the main structural form of long-span bridges, and even the only structural form of kilometer-level ultra-long-span bridges. Cable-supported bridges can be divided into cable-stayed bridges and suspension bridges according to the different cable arrangements. The two types of bridges have their own characteristics. For example, the stability of the cable-stayed bridge is better, while the span of the susp...

Problems solved by technology

[0007] Aiming at the problems of the existing FRP cable anchoring technology that the long-term anchoring performance is difficult to guarantee and the size of the anchor is too large, the present invention aims to provide an anchor with a smaller size and less prone to interfacial shear damage, which is suitable for pulling force greater than 50 tons.
