Light-Weight Temporary Bridge System and Building Method thereof

Abstract

A light-weight temporary bridge system includes a weight balance structure-module, constructed at a first abutment; a bridge tower structure-module, including a bottom part fixed to the weight balance structure-module and a top part coupled to the weight balance structure-module via at least one first cable; and a crossing structure-module constructed between the first abutment and a second abutment, coupled to the weight balance structure-module and coupled to the top part of the bridge tower structure-module via at least one second cable.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a light-weight temporary bridge system and building method thereof, and more particularly, to a light-weight temporary bridge system realized by the asymmetric cable-stayed bridge structure and building method thereof.[0003]2. Description of the Prior Art[0004]In recent years, nature disasters such as typhoons and flood frequently occur due to the extreme climate. When the serious nature disaster occur, bridges may be damaged and the road connecting to the mountain residual communities may be cut off, resulting in that the mountain residual communities become isolated and the transportation of the rescuer and relief supplies may encounter difficulties. In response to the situation of the nature disaster damages the bridges and the bridges cannot offer the normal traffic functions, many countries actively develop temporary bridges equipping with the feature of rapid assemblage, to relief ...

AI Technical Summary

Benefits of technology

The present invention is about a light-weight temporary bridge system that is made up of a weight balance structure-module, a bridge tower structure-module, and a crossing structure-module, which are all connected together. The weight balance structure-module is built on the first abutment, while the bottom part of the bridge tower structure is fixed to the weight balance structure-module and its top part is coupled to it via at least one cable. The crossing structure-module is constructed between the first abutment and a second abutment and it is coupled to the weight balance structure-module and to the top part of the bridge tower structure-module via at least one cable. The technical effect of the invention is the provision of a light-weight temporary bridge system that is easy to assemble and disassemble, and that can be moved around for temporary use in construction projects.

Problems solved by technology

In recent years, nature disasters such as typhoons and flood frequently occur due to the extreme climate.

When the serious nature disaster occur, bridges may be damaged and the road connecting to the mountain residual communities may be cut off, resulting in that the mountain residual communities become isolated and the transportation of the rescuer and relief supplies may encounter difficulties.

However, during the constructing processes of the cement culvert riverbed sidewalk and the steel temporary bridge, the workers are required to build foundation supports (e.g. bridge piers) at the riverbed.

If the nature disaster rapids the stream velocity of the river, the cement culvert riverbed sidewalk and steel temporary bridge cannot be constructed due to the safety concerns and the time of rescue and relief supplies entering the disaster areas is therefore delayed.

In addition, the materials and construction machinery of the cement culvert riverbed sidewalk and steel temporary bridge are hard to prepare which further delays the time of completing the cement culvert riverbed sidewalk and steel temporary bridge.
