The Chei-Lu Bridge lies in Nang-Tou County, crossing Chow-Shei Shi and connecting the Chei-Chei and Lu-Kou areas. The main span is a cable-stayed structure, and the approach bridges are simple support structures. Owing to seismic activity, there was much structural damage and displacement. We were involved in the repair project and in charge of these areas: pier cracks Epoxy injection repair, steel plate enforcement, deck cracks repair,retaining wall cracks repair, expansion joints repair, non-shrinkage cement grouting, exposed rebar repair, etc. The project was smoothly finished in 2001.
