This structure belongs to the District-level Cultural Relics, and is a three cross beam bridge spanning a river which suffered a partial and then total collapse in 2009.
When Cintec visited the site in 2018 all that was visible of the remains of the bridge were random sec-tions of stone beams partially or totally submerged in the river.
The Heritage Research and Conservation Center of Shanghai Jiao Tong University had asked Cintec to advise if the bridge could be reinstated utilising the Cintec system rather than the alternative scheme for-merly considered which would have been to support the structure on a steel-framed set beneath the pro-file of the bridge. This would be unsightly and expensive.
The length of the bridge is 17.1 meters, the width is 2 metres, the height of the pier is 3.2 metres, the thickness of the slab is 0.25 metres.
Fortunately the Jiao Tong University had carried out a full survey of the bridge and its’ many components and the fractures of each stone.
Cintec in conjunction with the Zhujiu Building Conservation Company, who are Cintec’s approved in-stallation company in China, based in Nanjing, developed a scheme using UK based structural engi-neering consultants MDHP who had many years of experience working with the unique Cintec system.
The design used Cintec GB20 anchors in a 50mm diamond core drilled hole to repair pieced together bro-ken stone components and to link together separate stones in vertical and hori-zontal planes thereby al-lowing the bridge to be re-assembled to the same pro-file as originally built but with no external visible evi-dence of support. Both the client and main contractor were extremely please with both the process and the outcome.
