Nizhou suspension bridge: An insight into deck erection gantries, Middlesbrough

Watch this event

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

We shall welcome everyone at 17:45 where you can network with some light refreshments. The talk will start at 18:15 with an expected close circa 19:30.

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

Mercedes Ascaso Til

Mercedes, principal engineer at DLT Engineering in Darlington, formerly Dorman Long Technology, has over 20 years’ experience in the construction engineering of bridges, tower systems and complex structures.

Mercedes was the chief engineer for the design of the 500 tonne capacity deck erection gantries in the Nizhou Suspension Bridge, in China. She is the first author of a paper, recently submitted for publication in the ICE Proceedings Bridge Engineering, which describes the gantries and focuses on the innovative movement system.

In her current role, Mercedes is chief engineer for the design of the deck erection gantries in the 1915 Çanakkale Bridge in Turkey, which will be the longest in the world when completed in 2023 (2023 m main span).
