建設工事現場用防音壁
Document Type and Number:
Japanese Patent JP6805069
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a soundproof wall for a balloon-type construction work site which reduces scattering of generated dust into an external space in a work space not subjected to restriction in a height direction.SOLUTION: A bag body 11 bulges due to the gas injected by an air compressor 8 and forms a wall body rising upward from the installation position between a work space S1 and an external space S2. The bag body 11 is held in an upright state by a rope 12 hooked on a peg 7 attached to the ground. A plurality of ejection ports 112 are provided at predetermined intervals, for example, on the line slightly closer to the work space S1 than the ridge line of the bag body 11 in an upright state, and the gas ejected from the ejection ports 112 forms an air curtain AC. The bag body 11 containing the gas therein attenuates the volume of the noise generated in the work space S1 and directed toward the external space S2. The air curtain AC regulates the movement of dust generated in the work space S1 and directed toward the external space S2. As a result, sound insulation and dust prevention in the external space S2 are realized.SELECTED DRAWING: Figure 1
