PILE DRIVER NOISE CONTROL EQUIPMENT
PROBLEM TO BE SOLVED: To provide a light-weight and inexpensive pile driver noise control equipment.SOLUTION: A pile driver noise control equipment 100 prevents noise due to contact between a pile driver 12 and a pile 10 when the pile 10 is installed. The pile driver noise control equipment comprises: a cardboard cover 14, which covers a section A where the pile driver 12 contacts with the pile 10; cardboard cover members 20, 22, which cover upper and lower openings 16, 18 of the cover 14; a noise leakage prevention member 24, which is disposed at a clearance between the cover members 20, 22 and the pile driver 12 and the pile 10 to prevent noise leakage from the clearance; and a reflection noise reduction member 26, which is disposed on an inner face 14a of the cover 14 and reduces the reflection noise.SELECTED DRAWING: Figure 1
【課題】軽量で安価な杭打ち機用防音装置を提供する。【解決手段】杭１０の打設時の杭打ち機１２と杭１０の接触による騒音を防止するための杭打ち機用防音装置１００であって、杭打ち機１２と杭１０が接触する部分Ａを覆う段ボールからなるカバー１４と、カバー１４の上下開口１６、１８を塞ぐ段ボールからなる蓋部材２０、２２と、蓋部材２０、２２と杭打ち機１２および杭１０との間の隙間に設けられ、この隙間からの音漏れを防止するための音漏れ防止部材２４と、カバー１４の内面１４ａに設けられ、反射音を低減するための反射音低減部材２６とを備えるようにする。【選択図】図１
