Tiivistelmä
The purpose of this thesis is the mechanical design of a noise reduction kit for a hydraulic impact hammer equipped with an adaptor used for installing sheet piles. The purpose of the noise reduction kit is to reduce the noise pollution generated from a sheet piling operation. This thesis was commissioned by Junttan BV, the Central European branch of Junttan Oy, a Finnish company that manufactures hydraulic pile driving machinery and equipment.
A sheet piling operation generates a considerable amount of noise pollution which is highly disruptive to nearby residents, businesses and wildlife. The sound levels generated from impact pile driving also exposes site personnel to potentially dangerous sound levels. Due to increasing environmental concerns and legislation, noise reduction is an increasingly desired aspect in the piling industry.
The project was carried out at Junttan’s Central European location in Nieuwegein, the Netherlands. The design was carried out based on the acoustic theory and input from personnel working in the industry. Detailed drawings and 3D models of the components involved in the prototype were created with the SolidWorks 3D CAD program and the physical prototype could be fabricated based on them.
The prototype, however, could not be manufactured within the timeframe of the thesis and preliminary sound reduction levels were obtained with theoretical calculations. The project will continue in an unspecified timeframe and the physical prototype will be manufactured and sound levels will be measured and compared to the theoretical calculations.
