Reduced vibrations are an important risk-mitigating property in driving piles.
In South Texas, KV Power is installing a new 138KV transmission line along a major highway, through Port Isabel and Laguna Vista to connect the Port Isabel substation to the Causeway Substation leading to South Padre Island and continuing through the resort community to the Sunchase substation. The foundation piles for the transmission line range in diameter from 76” to 32” (0.80 – 1.93m) with varying weights and length up to 75 feet (22,0m).
PVE Equipment USA has supplied our client with a 40VM vibratory hammer and PVE 800 Powerpack to drive these piles in varying soil conditions from silty sands to fat clays and with existing utilities less than 1 ft (30 cm) from the new structure.
With our Variable Moment technology, our client can reduce harmful vibrations during the start and stop of our vibratory hammer using this technology which is much safer and less destructive to existing structures and nearby utilities. The 40VM runs at 2000 RPM and has centrifugal force capable from 0-198 US tons (ca 100 tonnes) utilizing our patented variable moment technology.
PVE Equipment USA is very proud to support this project in Texas as we expand our horizons into other markets in the USA!
