Title:
IMPULSIVE SOUND SOURCE SIMULATING TUNNEL ENGINEERING BLASTING, AND EXPLOSIVE NOISE TESTING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2022/198840
Kind Code:
A1
Abstract:
An impulsive sound source simulating tunnel engineering blasting, and an explosive noise testing device and method, which relate to the technical field of tunnel blasting sound wave simulation and measurement. The impulsive sound source simulating tunnel engineering blasting is an impulsive sound wave generated by explosion of a detonating tube (1) triggered by a blasting machine (9). The explosive noise testing device comprises a model tunnel, a detonating tube (1), a blasting machine (9), a microphone (2) and a data acquisition instrument (3), wherein the model tunnel is composed of a plurality of model units (1#, 2#, 3#, 4#), and each of the model units (1#, 2#, 3#, 4#) is composed of a metal sleeve (4), a lining body (5), a testing hole (8), a connecting portion (6) and a handle portion (7). By means of adjusting different numbers of detonating tubes (1) to be simultaneously triggered at the same blast hole point position of the model tunnel, blasting noise of different quantities of explosives in a blast hole can be simulated, and the operating condition of delayed detonation in tunnel blasting can be simulated by using the millisecond delay blasting machine (9). The advantages of safety, reliability, simple operation and low cost are achieved.
