Security protection system used for steel reinforced concrete support blasting engineering

Abstract

The invention relates to a safe guarding system used in reinforced concrete supporting blasting engineering, which comprises a building safety net, a rubber protective blanket and a wire cable protective screening. The wire cable protective screening is connected with a stretch-draw anchor in a splicing way and is fixed on the upper part of a blasting reinforced concrete prop. An intermediate layer is the rubber protective blanket and an outermost layer is the building safety net. The system uses the wire cable protective screening to replace steel pipe scaffolds. The wire cable protective screening is flexible material and is not damaged after impact bending by slungshot. The covered rubber protective blanket is made of old and useless cover tyre bands of a bicycle, has toughness, flexibility and corrosion resistance which bamboo raft material does not have, and can fully absorbs impact energy of blasting slungshot. The rubber protective blanket also can reduce blasting noise, blocks dust, and furthest reduces various unsafe factors brought about by the reinforced concrete supporting blasting engineering. Steel pipe brackets do not need to be dismantled after blasting by using the blasting engineering; follow-up construction can be put into operation immediately, thus greatly accelerating the whole construction process and having immeasurable economic benefit.

Description

Technical field: [0001] The invention relates to a safety device for blasting engineering, and more specifically relates to a safety protection system for blasting engineering supported by reinforced concrete. Background technique: [0002] In the prior art, the demolition of reinforced concrete supports in foundation pits of newly built high-rise buildings is extensively applied to blasting technology, but the blasting flying stones, vibration, noise, and dust that accompany blasting demolition often bring unsafe factors. Among them, blasting flying rock is the most serious potential hazard of urban demolition blasting, which directly threatens the safety of people's lives and properties. In order to minimize these unsafe factors, a common method is to erect steel pipe bents to protect blasting flying stones. The most common materials on the construction site are steel pipes, fasteners and bamboo rafts. Large, steel pipes and bamboo rafts are more damaged after each blasti...
