Overview

All are welcome to this informative learning opportunity, irrespective of their level or discipline. Members of the public welcome.

The Nizhou Waterway Bridge, part of the Second Humen Bridge over the Pearl River in China's Guangdong province, is the second longest suspension bridge in the world (1688 m main span). The reinforced concrete towers are 257 m tall and the main cable spacing is 42.1 m. The deck is an aerofoil shaped orthotropic steel box 49.7 m wide and 4 m deep. Deck erection took place during the spring of 2018.

Three 500 tonne capacity deck erection gantries, supported on the main cables, lifted 175 deck segments into position in ten weeks. Strand jacks were used for deck lifting and gantry relocation.

The presentation will describe the deck erection gantries, from concept development, through detailed design and testing, to operation on site. It will focus on the innovations specifically developed for this project to reduce operating cycle times and overcome the design constraints. The gantry performance and the lessons learnt, based on the site feedback, will also be discussed.

The talk will take place in the main lecture theatre, Stephenson Building, Teesside University. For location see Teesside University Campus Map
