SUISUI SWAN method

Overview

The SUISUI SWAN(Segment Wings for an Arched New-bridge) method is a technique to create a continuous elevated bridge that takes landscape into consideration in a short period of time by assembling a full precast member applying an open-type arch bridge method, in order to eliminate railroad crossings causing traffic congestion and to revitalize the region.

Features

This method applies an open-type arch bridge method, and has a structural form assuming the assembly of three full precast members: 1. stand members, 2. half-divided arch beam members, and 3. transverse beam and slab members. Foundation piles and underground beams are constructed of cast-in-place concrete, but all division on the ground can construct viaducts by assembling full precast members, so that construction can be accelerated and landscape properties can be improved by curved beauty of arch shapes.
