Post-construction slit work "Noise measurement of cutting machines associated with seismic reinforcement work"
It is necessary to understand the characteristics of noise generated by the construction method.
In seismic reinforcement work for buildings, slits are constructed on the exterior walls. There are two methods for the slit construction: the conventional wall saw cutter and chipping method, and a dedicated cutting machine using special bits. In either method, noise is generated during cutting, so it is necessary to understand the characteristics of the noise produced by the method in order to preserve the surrounding environment during construction. 【Measurement Results of Maximum Noise Levels】 [Method: Renewal Slit Method, Cutting Method: Chipping] ○ Indoor Average: 102 (101) dB ○ Outdoor 5m: 95 (90) dB ○ Outdoor 7m: 83 (80) dB ○ Outdoor 30m: 70 (68) dB For more details, please contact us or download the catalog.
