The excavation then was backfilled to the level of the horizontal walers
Again, an interlocked sheet pile with walers
was used for the work pit which also required a continually-operated dewatering system," Heisler said.
The troopers and their walers
were to be called upon to exhibit these attributes many times during the ensuing two and a half years of hard campaigning in Sinai, Palestine and Syria.
England, the Mega Brace takes the place of conventional I-beams for use as a waler
system in a sheet pile/beam and plate installation, said Graham.
A two-bay, four-sided configuration was used with ClearSpan waler
I beams to provide an unobstructed opening of more than 28 feet.
The compare/will also refurbish slide rail system components, such as steel posts and panels; aluminum trench shields such as XLAP, aluminum modular Build-A-Box components such as panels and corner posts, and Corru-Lite (corrugated aluminum panel) shields; hydraulic vertical shores, hydraulic walers
, and hydraulic aluminum trench shields; and Stone Mizer bedding material container.
The parallel beams have rollers, and when horizontal walers
and sacrificial members are utilized, the entire cross-member apparatus can be easily removed resulting in an unobstructed clearance to the shored excavation
allow for maximum inside horizontal clearance and a four-point lifting system provides easier, safer handling.
A basic aluminum hydraulic shoring system may include cross-brace cylinders, vertical rails called uprights and horizontal rails called walers
The configuration also utilizes custom engineered external walers
Ross used an Efficiency ClearSpan Slide Rail System to facilitate the installation of a backwash holding tank by shielding the 24-foot deep open pit with panels, posts and walers
, without interfering cross braces.
Upon evaluation of the soil reports and blueprints, Efficiency Production recommended using a combination of their Universal Slide Rail System, with ClearSpan walers
, and a Shore-Trak cross trench utility system.
