discussion 9- sheet pile installation

From the video, sheet piles are driven into the ground with a vibratory hammer, which creates a lot of noise and vibration especially if anchors are needed. the project is in an urban area, that makes it more difficult for the surrounding structures. In addition to proper maintenance and operation of construction machinery, several means of controlling construction noise impacts will be employed as needed, and as may be practical, including. Avoid nighttime activity; Operate equipment during daylight hours to limit any potential disturbance during the nighttime (sleep interference) periods, to the extent possible, in accordance with the local Noise Ordinance; and Use of a High Frequency/Variable Moment Vibratory Hammer. Acoustical insulation material: It can be attached to the inside of any construction-related fencing or supports that may be installed around the work area or can be attached to the inside of the chain link fence that runs along the northern perimeter of the Site. This mitigation method may serve to suppress ground- level noise generation and may decrease the potential noise levels to pedestrian foot traffic. Reducing the load on a vibratory hammer; both normal and high frequency,` has proven beneficial at similar remediation sites and is an effective method of reducing both noise and vibration. Also, reducing load, in combination with the use of a high-frequency vibratory hammer, has shown to decrease pile-driving related noise and vibration.
