Abstract

The invention relates to an air bubble curtain generating device used for blocking deepwater blasting shock waves and a using method thereof. The air bubble curtain generating device is formed by connecting 1-5 high-pressure gas generating-releasing devices (1) through a connecting tube (2) and a gas injecting tube (3) or is formed by directly connecting the 1-5 high-pressure gas generating-releasing devices (1) to the gas injecting tube (3). Liquid-state gas (12) is filled in a housing of each high-pressure gas generating-releasing device, wherein the two ends of a resistance wire (11) in thehousing are correspondingly connected with ends of two guide wires (5) through two copper columns (8), the other ends of the two guide wires (5) are connected with a power supply (4) through a sealing cover (6), the high-pressure gas connecting tube at the outer side of the sealed end of the housing (13) communicates with a cavity of the housing (13), and a counter bore at a through hole of the cavity is equipped with a fixed-pressure energy-release sheet (15). The air bubble curtain generating device is simple in structure, is low in cost, is easy to operate, and has a more remarkable blocking effect, on blasting shock waves, under an a deep water environment, especially an ultra-deep water environment.

Description

technical field [0001] The invention belongs to a bubble curtain generating device. In particular, it relates to a bubble curtain generating device for blocking deep water blasting shock waves and a method for using the same. Background technique [0002] At present, underwater blasting is widely used in many fields of the national economy, such as hydropower stations, ports, bridge construction, dredging of water channels, and military protection, etc. The research on the safety of underwater blasting is particularly important. Among them, the shock wave of underwater blasting is one of the main hazards of underwater blasting construction. The shock wave of underwater blasting has the characteristics of large amplitude and long-distance propagation, which has strong harm to underwater structures, construction personnel, fish, etc. Bubble curtain protection technology is currently the most direct and effective means of shock wave protection for underwater blasting. Bubble...
