A protective structure for blasting noise and flying rocks and its construction method

Abstract

The invention relates to a protection structure for blasting noise and flying stones and a construction method thereof, comprising spring mattresses covering blastholes of blasting bodies and distributed in arrays, two adjacent spring mattresses are connected together by iron wires, and finally The outside side of the outer spring mattress is also connected with sandbags through iron wires; each spring mattress is stacked with a palm fiber mattress, and a tire is stacked on the palm fiber mattress, and the tire is connected by iron wire and palm fiber. The mattress sides are joined together. The invention can prevent and control blasting flying stones, reduce blasting noise, reduce blasting impact noise by 60%, and blasting network is safe, and is mainly used for open-air shallow hole blasting construction in cities and towns; it is convenient for processing and installation, environmentally friendly and economical, and can be reused; The construction process is simple, construction personnel do not need any special training or skills other than blasting, and have low technical requirements for construction personnel.

Description

technical field [0001] The invention relates to a protection structure for blasting noise and flying stones. Background technique [0002] Flying stones and noise are two harmful effects of blasting, which have always been an important issue in the blasting industry. The production of a large number of blasting flying rocks can be effectively controlled and the blasting noise can be reduced by optimizing the blasting design and careful construction, but it is absolutely impossible to produce individual blasting flying rocks and the blasting noise can meet the requirements of the urban environment, which cannot be achieved under the current blasting technical conditions. Therefore, the safety protection work of blasting flying rocks and noise reduction is essential. [0003] At present, the commonly used protective measures for blasting flying rocks are: directly covering the blasting body with sandbags, waste tapes, rubber curtains, bamboo fences, barbed wire, waste tire sk...

AI Technical Summary

Problems solved by technology

Blocking the normal propagation of sound waves through special bent frames is a noise protection technology commonly used in open-air blasting; in open-air demolition blasting construction, the use of water-sealed hole technology and water bag covering technology can also effectively reduce noise. The wave-stopping wall or bent frame construction is difficult and expensive; the water bag in the water-sealed hole and water bag covering noise reduction technology is easy to break before blasting, resulting in failure of noise reduction, and the lost water will cause the explosive to be damp and affect the blasting effect and safety.
