Example Embodiment

[0022] Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail:

[0023] like Figure 3 to Figure 5 The sheathing element 4 shown is a half-pipe body with a tenon pin 2 and a tenon-groove 3 at the two joints respectively, and a raised helical rib 1 is provided on the outer side of the half-pipe body; such as figure 1 , figure 2 The shown method of installing the plurality of sheath elements 4 on the cable is carried out according to the following steps: A. Install the first sheath element: cover the first sheath element outside the side of the cable; B. Install The second sheathing element: insert the tenon 2 of the second sheathing element into the tenon groove 3 of the first sheathing element, and engage with each other to form a circular tube, so that the cable is enclosed in the circular tube, and the two The ends of each sheathing element are staggered by a certain distance, so that the spiral ribs 1 on their oute...

Abstract

The invention discloses an installation method of an inhaul cable protecting bush and relates to the technical field of architectural engineering. Protecting bush elements are adopted and each protecting bush element is a half-tube body which is provided with a draw-bore pine and a mortise, wherein the draw-bore pin and the mortise are arranged on two joint parts. The installation steps are as follow: A, the first protecting bush element is sleeved on the exterior of the side of an inhaul cable; B, the second protecting bush element and the first protecting bush element are fastened and then sleeved on the exterior of the inhaul cable so as to enable end heads of the first protecting bush element and the second protecting bush element to be staggered; C, the third protecting bush element and the second protecting element are fastened and then sleeved on the exterior of the inhaul cable, and end heads of the third and the first protecting bush elements are in butt joint; and D, according to the step C, the protecting bush elements are installed on the exterior of the inhaul cable one by one until the protecting bush elements are all installed on parts, which need to be protected, of the inhaul cable. The method is simple and easy to practice, and prevents the inhaul cable protecting bush and a steel cable from being damaged.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for installing a protective cover of a construction cable. Background technique [0002] With the rapid development of long-span bridge construction, cable-stayed bridges and suspension bridges are more and more widely used. Steel wire cables are the key components used in cable-stayed bridges and suspension bridges. Then insert the high-density polyethylene sheath. The cable sheath acts as an anti-corrosion effect for the steel wire rope. At present, the installation of the cable sheath must be done before the two ends of the cable are fixed. The cable is then welded piece by piece to the required length. In this construction method, the inner wall of the sheath may be damaged by the steel wire of the cable during the cable threading process, and the welded section needs to be planed before the sheath is welded, and a certain space must be left betwee...
