[Construction Case] Road Bridge Pier Disaster Recovery Work "Conback Method"

It is possible to use it for disaster recovery work in a small site! Examples of on-site cast-in-place stabilization block construction method.

We would like to introduce a case study of the "Conback Method" used for the restoration work of road bridge piers after a disaster. In this site, there is a road bridge located above the existing railway tracks, and during heavy rainfall, the foundation of the road bridge pier near the river was eroded. Considering the impact on the railway tracks, it was necessary to urgently implement disaster recovery work. There was a challenge due to the narrow access for transporting materials and equipment, making it difficult to bring in resources using conventional methods. To address this issue, we proposed the use of the on-site cast box-type stabilization block method, which was adopted. [Case Overview] ■ Adopted Method: On-site cast box-type stabilization block "Conback Method" ■ The Conback Method can be used for disaster recovery work in narrow sites. ■ A wire mesh panel made of zinc-coated iron wire, processed into a U-shape, is assembled on-site into a box shape, and a bag made of synthetic fiber sheet is set inside. After installation at the construction site, concrete is poured into the bag, forming the on-site cast stabilization block method. *For more details, please download the PDF or feel free to contact us.
