Abstract

The invention provides a self-anchoring type mounting method of a suspension bridge. The method comprises the steps of constructing a main pier and a side pier; erecting beams and splicing through a crane; mounting a medium supporting pier of a side span steel box beam; mounting the side span steel box beam; mounting a temporary steel tower; mounting a main span steel box beam and a temporary cable; mounting a main cable and a lifting cable; converting the systems. The method is free of the limitation of navigation of a waterway; an ultrahigh bracket cannot be constructed in the river at a gorge region with steep bank slopes, so that the input is reduced; the longitudinal moving load can be decreased, and the longitudinal moving range, so that the long-distance and large-tonnage propping and pushing can be avoided, and as a result, the risk of construction safety in longitudinal moving can be reduced; a propping pushing bracket can be avoided being scoured by flood and floating articles, so that the safety risk of construction is reduced, and the construction is sped up.

Description

technical field

[0001] The invention belongs to the technical field of bridge construction, in particular to a method for installing a self-anchored suspension bridge. Background technique

[0002] With the rapid development of my country's economy and society, infrastructure construction is changing with each passing day, bridge construction technology is constantly improving, and long-span self-anchored steel box girder suspension bridges are gradually increasing. The construction of a long-span self-anchored suspension bridge across rivers, lakes and seas is extremely difficult due to the influence of hydrogeological conditions.

[0003] Using the existing technology to erect a long-span self-anchored suspension bridge across rivers, lakes and seas requires a large investment and high risks. The construction process of the self-anchored steel box girder suspension bridge is generally as follows: first install the steel box girder main girder, then install the main cable ...
