Preparation of anchor material for main cable strands of ultra-high-strength large-diameter steel wire and method of anchoring

Abstract

The invention discloses an ultra-high-strength and large-diameter steel wire main cable strand anchoring material and an anchor filling method, and relates to the technical field of main cable strand filling and anchoring. In terms of material quantity ratio, the mixing ratio of unsaturated polyester resin is 13% to 14%, the mixing ratio of curing agent is 1% to 1.6%, the mixing ratio of accelerator is 1% to 1.6%, and the mixing ratio of other auxiliary materials The proportion is 3.4%-4%, rare earth element 0.08%-0.38%, metal element 1.35%-1.73%, smelting metal material 71.3%-72.8%, including the following steps: S1: unsaturated polyester resin, curing agent, accelerator Mixing agent and other auxiliary materials according to the proportion to make resin anchoring agent; S2: use the mixed resin anchoring agent to pour and anchor the cable strand; S3: use mortar to wrap and cast the outer layer of resin anchoring; S4 : Mix and smelt rare earth elements and metal elements in proportion.

Description

technical field [0001] The invention relates to the technical field of main cable strand filling and anchoring, in particular to an ultra-high-strength large-diameter steel wire main cable strand anchoring material and a filling and anchoring method. Background technique [0002] The construction method of the suspension bridge was invented in the early 19th century, and many bridges use this construction method. Modern suspension bridges are evolved from cable bridges. The scope of application is mainly long-span and super-long-span highway bridges, and all large-span bridges today use this structure. It is the main form of long-span bridges. Suspension bridges are bridges with cables or chains that bear tension as the main load-bearing components. The main load-bearing component of the suspension bridge is the suspension cable, which mainly bears the tensile force and is generally made of steel with high tensile strength (steel wire, steel cable, etc.). Because the susp...
