Abstract

A method and system for suspending oblique stay cables of the cable-stayed bridge includes such steps as installing guide rope; installing the slide element able to slide along guide rope, suspending the front end of oblique stay cable by the first drawing mechanism composed of lifting cable, fixed pulley block and lifter, suspending said slide element by the second drawing mechanism consisting of drawing cable, fixed pulley block pair and manually or mechanically drawer, fixing the oblique stay cable to said slide element, and suspending said oblique stay cable to the specified position by the first and the second drawing mechanisms. Said method can solve the problems of the deflection of stay cable due to too great a weight and the difficulty for suspending it.

Description

A kind of cable stayed bridge hanging method and suspension of suspension cable
The present invention relates to hanging method and the device of a kind of cable stayed bridge with suspension cable.
In the installation of in the past guy of twisted steel cable for cable stayed bridge, generally be with a drag cable, tie steel strand one end for one of this drag cable, the other end of drag cable is connected with hoist engine by two fixed pulleys, starts hoist engine the steel strand traction enhancement is put in place.Oversize as more than 1000 meters the time when drag-line length, guy of twisted steel cable weight reaches more than 1 ton, and the big sag of its weight is also very big, and except that requiring bigger tractive force, steel strand are sagging, with the ground friction, easily scratch steel strand surface, and drag-line is installed difficulty.
The object of the present invention is to provide a kind of cable stayed bridge hanging method and the suspension with guy of twisted steel cable, this hanging method has solved longer guy of twisted steel cable, and to hang in the rope construction steel strand overweight sagging, scratches and hang the problem of rope difficulty with ground friction.
For reaching above-mentioned purpose, the present invention's cable stayed bridge adopts the installation guide rope, the sliding part that can slide thereon is installed on this guide rope with the hanging method of suspension cable, by the front end of first haulage gear suspention suspension cable, hang the method and system of above-mentioned sliding part and movable and fixed pulley and usefulness by second haulage gear.
Its hanging method step comprises:
1) guide rope is installed, the one end is connected with the beam body, the other end makes guide rope be oblique upper to being connected with body of the tower top;
2) sliding part that can slide is installed thereon on this guide rope;
3) pass through the front end that first haulage gear suspends suspension cable in midair;
4) hang above-mentioned sliding part by second haulage gear;
5) suspension cable is fixed on the above-mentioned sliding part, the point of suspension of the front end of this fixed point and above-mentioned first haulage gear and suspension cable keeps suitable distance, so that this suspension cable can be suspended from specified altitude;
6) drive above-mentioned first and second haulage gears, above-mentioned suspension cable is suspended from assigned position;
The present invention's method and system has the following advantages:
1, adopt two haulage gears to act synergistically simultaneously, alleviated construction labour intensity, accelerating construction progress has reduced construction cost;
2, hook suspension cable with one to a plurality of sliding parts, upwards slide, overcome long overweight steel strand sagging problem along guide line, the one, avoided guy of twisted steel cable and ground friction by the surface of scratch steel strand, the 2nd, laborsaving.
Below in conjunction with drawings and Examples the present invention's cable stayed bridge hanging method and the suspension with suspension cable is described further.
Accompanying drawing is the suspension structure signal of cable stayed bridge of the present invention with suspension cable.
