Problems solved by technology

There are some problems in the construction of traditional cable-stayed bridge tower cable conduits: 1. Due to the high requirements for the positioning and installation accuracy of the cable conduits, welding on the rigid skeleton cannot be positioned with high precision, which affects the construction accuracy
2. Due to welding, external force collision and other reasons, the positioned cable guide will be deviated
3. Two separate hoistings will affect the construction period and increase the safety risk of high-altitude hoisting operations

Embodiment Construction

[0052] Such as Figure 1 to Figure 8 A cable guide positioning method for a cable-stayed bridge shown, the method may include the following steps:

[0053] Step 1. Installing the first adjusting part: set up sliding grooves 2-1 on the two supporting rods 2 of the rigid frame 1, and the sliding grooves 2-1 are arranged along the height direction of the supporting rods 2, so that The sliding groove 2-1 is arranged on the upper part of the support rod 2; the first adjusting member 3 is horizontally pierced in the sliding groove 2-1, and the first adjusting member 3 can move along the sliding groove 2-1 move up and down; the end of the first adjusting member 3 passes through the support rods 2 and extends between the two support rods 2;

[0054] Step 2, install the second adjusting part: weld two second adjusting parts 5 horizontally on the outer surface of the cable guide 4, and the two second adjusting parts 5 are arranged symmetrically on the top of the cable guide 4;

Abstract

The invention discloses a cable-stayed bridge cable guide pipe positioning method. The method comprises the steps of 1, mounting a first adjusting piece; 2, mounting a second adjusting piece; 3, mounting a cable guide pipe and an adjusting frame; 4, mounting a hoisting platform; 5, adjusting and fixing a stiff skeleton; and 6, adjusting the cable guide pipe. When the position of the cable guide pipe is finely adjusted, the offset position and the offset direction of the hoisted cable guide pipe are determined according to the included angle between the projection of the central axis of the hoisted cable guide pipe and the projection of the calibrated central axis of the cable guide pipe in the same horizontal plane or the same vertical plane; and by adjusting the position of the adjusting frame or the number of the gaskets, the purpose of correcting the deviation of the cable guide pipe is achieved, positioning of the cable guide pipe is more accurate, the positioning accuracy of the cable guide pipe is improved, the frequency of adjusting the position of the cable guide pipe is reduced, the construction difficulty during positioning of the cable guide pipe is lowered, and the workload of field measurement is reduced. The construction period is shortened, and construction operation is simpler.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a cable guide positioning method for a cable-stayed bridge. Background technique [0002] The cable-stayed bridge is a high-order statically indeterminate structure with complex forces, large mutual influence between components, and controllable internal force and linearity. Among them, the stay cable is the link connecting the tower and the beam, and the measurement result of the cable force is the basic basis for the monitoring of the cable force, and its accuracy directly determines the construction quality of the stay cable. The cableway pipe is an important component that anchors the two ends of the cable to the main tower and the main beam respectively. In order to prevent the cable from being damaged by friction with the nozzle of the cableway pipe, it will affect the quality of the project and prevent the eccentricity of the anchorage. The additio...
