BRUCE Vibro Ensures the Fundamentals of Wall Design
Engineers are using the BRUCE Vibro Hammer, a crane-suspended type with 92 tons of centrifugal force and Power Pack PQ-400V with 400 liters per minute of maximum flow, at Kimpo, Korea, to install steel sheet piles and construct a three-story steel-intensive underground basement for a major apartment project.
Engineers can select the most productive and economical vibrating equipment that meets the construction designer’s criteria only after properly defining the job site conditions, performance expectations, and longevity goals.
Therefore, engineers must first clearly establish and document the goals, end users of the project, and the wall structure itself to ensure a successful design.
The BRUCE Vibro helps engineers answer key questions about the project’s final objectives, such as “What is the main purpose of the structure?” and “What specific performance goals are needed to achieve that purpose?” by analyzing potential environmental impacts and ensuring compliance with all relevant regulations and permits.
BRUCE SGV-300
12 meter of sheet piles were installed to form a medium dense soil filled temporary cofferdam over a 50 meter. The sheet piles were installed using a 70 tons of Leader fitted with a 0.866 inch of maximum amplitude of Vibro Hammer SGV-300.
RUCE SGV-300 boasted of a high-powered hydraulic clamp with 140 tons of clamping force that, once it gripped a pile, never released it until the operators pressed off the clamp switch.
In the permanent state, construction workers drove the sheet piles to resist the earth and water pressure when they supported them at basement and intermediate floor slab levels.
Engineers have also assessed the piles for their vertical load-carrying capacity and have accounted for it in the basement structure and foundation design.
To select the right vibro hammer for a given job, engineers must consider some driving condition factors that influence penetration speed, such as soil condition, vibro force (amplitude, centrifugal force), and pile weight.
The engineers finally selected BRUCE Vibro SGV-300 with 92 tons of centrifugal force, which should generally be 15 times greater than the pile weight, and used it to carry out a basement foundation piling job with a 20-meter pile.
