Embodiment Construction

[0085] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0086] The reef blasting area in this embodiment is located in the main habitat of white dolphins. The wild protected animals are mainly white dolphins. The target animal of this blasting is white dolphins. For the sake of prudence, the first blasting should be carried out according to the blasting safety regulations. Safe distance (upstream 1500m outside, downstream 1000m outside) carries out vigilance, safe distance is apart from blasting point ou...

Abstract

The invention puts forward a construction method for reducing underwater blasting noise. Single-sound delayed continuous blasting is adopted, and through single-sound delayed continuous blasting, the blasting efficiency is improved, the blasting construction frequency is reduced, and the channel occupation time is shortened; under the condition of controlling the explosive quantity in a sound, the interval between every two shots is adjusted through nonel detonators which are delayed for one second, and the explosive quantities used between every two adjacent shots are different, so that superimposed resonance between every two adjacent shots can be effectively prevented from being generated, and the blasting noise is controlled within a fishery protection threshold value; and wild animals are repelled before blasting, so that the interference of the blasting noise on the wild animals can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of underwater blasting construction, in particular to a construction method for reducing the noise of underwater blasting. Background technique [0002] Underwater blasting refers to blasting under the water surface, on the surface of underwater soil and rock, or inside the underwater rock formation. It is generally used for civil purposes to blast off reefs, dredge waterways, deepen ports, dig foundation pits, trenches, and open water diversion tunnels underwater. [0003] The main underwater noise in underwater blasting construction comes from underwater drilling and blasting. Underwater drilling and blasting will generate strong shock wave noise in the water. Excessive blasting noise will cause harm to marine life. At present, the noise reduction of underwater blasting mainly controls the blasting noise by limiting the amount of blasting charge in a single stage. The amount of blasting charge in a single ...
