Work on the LIRR/MTACC project will include construction of the below-grade facilities at the Plaza Interlocking, including installation of waterproofing systems, removal of temporary struts and walers
and other temporary support measures within the open cut excavation constructed by other parties.
HP14 by 117 pound I-beams were used as walers
, hauled into the excavation and held in place horizontally by the excavator while a welder tacked them to the vertical beams in the caissons.
Sandy", the former mount of Major-General Sir William Throsby Bridges, (whose body was returned to Australia and buried on Mount Pleasant in Canberra as described in Joe's feature in Sabretache, September 2004) was the only one of over 136,000 Walers
returned to Australia after serving in WWI.
Many of them obviously decided to transfer to the 2nd Divisional Cyclist Company in the belief that the Middle East was to be a sideshow and that if the only way of getting to the Western Front to see action was to swap their Walers
for bicycles, then, so be it
The work pit was approximately 40-feet long and 15 feet wide interlocked with sheet pile with steel beam walers
Although both troopers and walers
were tired, the Light Horsemen were jubilant at the success of the raid.
What makes the Mega Brace system unique compared to I-beam walers
is that a six-inch telescoping hydraulic ram is pinned to the ends of the I-beam extensions or struts.
They do not require interior walers
or beams which provides more working space in the excavation.
There is no need for interior walers
or beams, which allows for more working room and ease while digging.
The three traditional shoring methods for four-sided pits: tight-sheeting, welded walers
or four-sided trench shields, were dismissed at bidding because the excavation needed to stay in the utility easement, and there were many mature trees and houses around the site.
In addition to using 8-feet by 20-feet (4-inches thick) and 8-feet by 16-feet (4-inches thick) panels, 55-foot external Walers
, braced to spreader and corner posts, were used to provide clear span accessibility.
