Ситуация

The Kaikōura M7.8 Earthquake caused widespread damage to the road and rail corridor 20 km North and South of the Kaikoura township. Over 40 major slips inundated the road and rail with over 750,000 m³ of material from source zones up to 500 metres above sea level. The highly fractured Grey Wacke meant frequent future rockfalls were expected. The rockfall frequency and wide run-out area at SR8 and 9 created the requirement for a system that attenuated the rockfall energy to a manageable level, was quick to install and required minimal future maintenance. The slope, on average, is approximately 50 degrees, but in some parts, it is nearly vertical.

Описание

A 110 metres wide rockfall attenuator (ATT - 60) with a 35 to 40 metres tail which enables the attenuated material to pass down through to the lower section for clearing if required. The 65 mm aperture is small enough that no secondary mesh is required, and the ULTRACOATING ensures design life in the coastal environment. The attenuator system utilises a 3 metres high hinged post with a 16 metres spacing and a support rope separation halfway.  A double-top rope was installed for increased safety in design, and Type III flex heads were installed to transfer the load to the Gewi 32 anchor bar. Overall, the attenuators create a quick and cost-effective solution.
