Abstract

The invention discloses a protection device for vertical shaft tunnel blast construction. The protection device comprises a protection cover capable of being assembled and is characterized in that the protection cover capable of being assembled comprises I-shaped steel used for manufacturing a skeleton; the I-shaped steel is fixedly connected with a steel plate; the I-shaped steel and the steel plate form a half-open rectangular framework; and hoisting rings are arranged on the steel plate side by side. By hoisting and fixing the protection device before blast, sound insulation, noise reduction and flying rock protection can be achieved during blast, and the protection device can be pulled out and hoisted out after blast; construction is easy and convenient, and protection is safe and reliable; and the problem of harm of blast noise and blast flying rock to peripheral civil houses and personnel is effectively solved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a shaft tunnel blasting construction protection device and a construction method thereof. Background technique [0002] With the continuous development of urban rail transit in my country, the construction of tunnels has entered a peak period. The environmental impact caused by tunnel construction in urban dense areas has become a hot issue in the research of underground engineering circles in recent years. The construction environment is complex, and the owners have a high awareness of rights protection. Blasting construction in dense urban areas will inevitably affect the lives of residents and cause serious social impacts. [0003] Since the excavation of the foundation pit is adjacent to houses, safety accidents and disturbing phenomena, such as blasting noise and flying rocks, are likely to occur. The hazards of blasting flying rocks are mainly reflected in c...
