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:
The present invention relates to a kind of blasting engineering safety device, more specifically to a kind of security protection system that is used for steel reinforced concrete support blasting engineering.
Background technology:
In the prior art, the dismounting that newly-built high building foundation pit reinforced concrete supports applies to blasting technique in a large number, but follows demolition blasting and the blasting flyrock, vibration, noise, the airborne dust that come often bring unsafe factor.Wherein blasting flyrock is the most serious potential hazard in urban demolition blasting, is directly threatening the safety of people's lives and properties.For dropping to these unsafe factors minimum, the normal way that adopts is to set up steel pipe framed bent protection blasting flyrock, the maximum material in job site is exactly steel pipe, fastener and bamboo raft, to carry energy bigger but because armored concrete supports rubble that explosion produces, the damage of steel pipe, bamboo raft is more after the explosion at every turn, and can not stop blasting flyrock, usually causes security incident, therefore need to enlarge the blast warning scope, big to the influence of surrounding enviroment public safety.Though present conventional blasting protection method has been paid huge cost, effect is still undesirable.
Summary of the invention:
The present invention seeks to provide a kind of and can bear enormous impact power, can not penetrated by the slungshot that explosion produces at the prior art weak point, repeatedly long service life, and can reduce the security protection system that is used for steel reinforced concrete support blasting engineering of Property of Blasting Noise simultaneously.
The objective of the invention is to realize: a kind of security protection system that is used for steel reinforced concrete support blasting engineering by following measure, include the building safety net, its special character is to also have: preventing rubber blanket and wire rope net, described wire rope net splicing stretch-draw anchor is in the top that explosion armored concrete supports, the intermediate layer is the preventing rubber blanket, and outermost layer is the building safety net.
Described wire rope net is made up of the suspension ring of four jiaos on frame, web-roll core, frame, and described web-roll core connects and composes by intersect splice through, latitude steel wire rope, and web-roll core is connected with frame steel cable splice through, latitude steel wire rope.
Described frame is provided with aluminium alloy compacting joint for four jiaos.
Described warp, latitude steel wire rope can be along the horizontal, vertical direction braidings of frame.
Described warp, latitude steel wire rope can weave along the frame diagonal.
Described preventing rubber blanket intersects upper and lower woollen yarn knitting by some warps, latitude band and constitutes the rectangle blanket, through, latitude band after the blanket edge break returns by bolt or fixation with steel wire.
Described band is the waste and old cover tire of bicycle.
Described band is waste and old conveyer.
Compared with prior art, the security protection system that is used for blasting engineering that adopts the present invention to propose, body series has adopted the wire rope net to substitute scaffolding steel pipe, and it is a flexible material, is subjected to can not damage after the slungshot impact bending; And the preventing rubber blanket that covers is made by the waste and old cover tire band of bicycle, and its toughness, elasticity and corrosion resistance are that the bamboo raft material can't possess, and can fully absorb the impact energy of blasting flyrock, and blasting flyrock can not penetrate rubber blanket.This rubber blanket can also reduce Property of Blasting Noise, blocks dust, the various unsafe factors that reduce steel reinforced concrete support blasting engineering to greatest extent and brought.The preventing rubber blanket adopts the waste and old cover tire braiding of bicycle to form fully, for the regeneration of waste old, utilization have rationally proposed a kind of method of wisdom, also can save a large amount of bamboo woods simultaneously, reduces the consumption of blasting protection material, and its economic benefit is apparent.Adopt blasting engineering of the present invention, owing to adopt tension structure, after the armored concrete explosion, need not to remove steel pipe support, can drop into follow-up construction immediately, each explosion circulation is one day duration at least in advance, can accelerate the duration of whole armored concrete supporting removal engineering greatly, the duration shortening of the whole construction-engineering project that brings thus will produce immeasurable indirect economic effect.Adopt the effectively generation of controlled blasting slungshot accident of the present invention, reduce the harm that demolition accident is brought, realize rapidly and efficiently, high safe, high-quality demolition effect.

The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated:
Fig. 1～Fig. 2 is a conventional security protection network structural representation.For removing the unnecessary support of armored concrete in the foundation ditch, need set up steel pipe support 11 in advance, on the horizontal pipe support of steel pipe support, set up the first road steel pipe supporting surface 12, bamboo raft 13 is laid in the supporting surface top, above bamboo raft, set up steel pipe supporting surface 14, the second supporting surfaces top, second road and prick knot building safety net 15.Steel pipe support and setting up all of supporting surface need spend a large amount of labours before and after the explosion.
Fig. 3 has provided the structural representation of the embodiment of the invention.A kind of security protection system that is used for steel reinforced concrete support blasting engineering includes building safety net 15, preventing rubber blanket 4 and wire rope net 3.Described wire rope net splicing stretch-draw anchor is in the top that explosion armored concrete supports, and the intermediate layer is the preventing rubber blanket, and outermost layer is the building safety net.
The wire rope web frame schematic diagram that Fig. 4 adopts for the embodiment of the invention.Described wire rope net 3 is by frame 31, and four jiaos of web-roll cores 32, frame are made up of suspension ring 33.Four jiaos on frame can be provided with aluminium alloy compacting joint 34, forms suspension ring by self steel wire rope.Described web-roll core is connected and composed by warp, latitude steel wire rope intersection splice, and warp, latitude steel wire rope can also can be pressed the braiding of frame diagonal along the horizontal, vertical direction braiding of frame.Web-roll core warp, latitude steel wire rope are connected with frame steel cable splice.The wire rope net substitutes original steel pipe scaffold, and it is a flexible structure, absorbs the impulsive force that is subjected to slungshot by plastic deformation, and is not fragile, can use repeatedly.Can adjust the size of steel rope according to the size of actual blasting engineering force of explosion, the size of web-roll core mesh.
