Embodiment Construction

[0033] The specific implementation of the invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figure 1-3 As shown, a buckle cable 1 anchoring method of a cable hoisting system, comprising

[0035] 1) Excavate the ground anchor pit and support the formwork;

[0036] 2) Pre-embedded finishing thread is set in the ground anchor pit, and the ground anchor concrete 6 is poured in the ground anchor pit to form a plain concrete ground anchor;

[0037] 3) Install the steering force transmission component on the plain concrete ground anchor and penetrate the finished thread, and tighten it with a nut;

[0038] 4) The buckle cable 1 is located at one end of the arch rib to anchor the steel strand; the buckle cable 1 is located at the ground anchor end, and the steel strand of the buckle cable 1 penetrates the steering force transmission member and locks it; according to the requirements of the elevation of the arch rib and the cab...

Abstract

The invention discloses a buckle cable anchoring method of a cable hoisting system, which belongs to the technical field of bridge engineering construction. Including 1) excavating the ground anchor pit and supporting formwork; 2) setting pre-embedded finishing threads in the ground anchor pit, and pouring ground anchor concrete into the ground anchor pit to form a plain concrete ground anchor; 3) turning the The force transmission member is installed on the plain concrete ground anchor and penetrates into the finished thread, and is tightened by a nut; 4) The anchor cable is located at one end of the arch rib to anchor the steel strand; the anchor cable is located at the ground anchor end, and the steel strand of the anchor cable passes through Insert the steering force transmission member and lock it; According to the elevation requirements of the arch rib and the cable force control requirements, the buckle cable steel strands are stretched until the target elevation and cable force are reached.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a buckle cable anchoring method for a cable hoisting system. Background technique [0002] The arch ribs of arch bridges are generally installed by cable hoisting system. When the arch ribs are installed and constructed by cantilever, because the arch feet are designed as hinge supports, the arch feet can be rotated, and the strength of the arch rib itself is limited, so a cable-stayed buckle-hanging system is required to pull the arch ribs to balance the self-weight and overturning moment of the arch ribs. [0003] The fastening system consists of steel strand fastening cables, fastening towers, arch rib buckle point structures, steering saddles on fastening towers, buckle point exchange beam structures, lateral cable wind cables for hoisting segments, and buckle ground for each hoisting segment. The anchor and buckle cable tension end structure are jointly composed...
