Abstract
The utility model relates to a demolish flexible dustproof protection network of blasting accompanies the sponge layer between fixed network and the protection network, fixed network, protection network and sponge layered suture system are in the same place to the loop bonding line, or the binding thread is in the same place fixed network, protection network and sponge layer ligature at the several position. The utility model discloses a flexible protection system, protection network, sponge all have the function of absorbing blasting impact energy, can realize nevertheless not fully enclosed protection of all standing to demolising the blasting, used repeatedly many times can be realized to the protection network, practices thrift the cost, the utilization absorbs water the sponge and assaults the atomizing water droplet that broken effect produced down in the blasting, can realize the effective control to blowing up the dust, because material and the thickness of sponge are adjustable, dustproof protection network is adjustable with the distance in big gun hole during the use, can realize that the blasting of different effects is dustproof. The utility model discloses easy, the light and construction convenience of simple structure, material, range of application are wide.
Description
Technical field
The utility model relates to blasting engineering field, is specifically related to a kind of demolition blasting flexible dustproof protection network.
Background technology
Explosion is the efficient construction means that City Building is removed, and can save manpower and mechanical work, the reduction of erection time, reduces construction cost.But the slungshot caused when bursting work exists demolishing buildings explosion in larger safety and environment hidden danger, particularly city, shock wave bring security threat can to Nearby Structure and resident etc.; The dust coverage that explosion causes is large, pollutes urban air.Therefore, the security protection of urban architecture demolition blasting and dust-proof very important.No matter be the blasting protection system that traditional bamboo wood, plank, steel plate or sandbag is formed, or the flexible protection systems of recent invention, all do not have to solve protection and dust-proof problem well simultaneously.As CN104236405A) disclose one " demolishing buildings explosion flexible protection systems ", it protects straw screen or mat, elastic fixing device and anchor pole to form by one deck, two-layer or layer flexible protection network, protection network.Protection network hides or hangs and surround building to be removed, and is fixed on ground and roofing or metope by elastic fixing device anchor pole; For another example CN103424045A discloses deep basal pit lithosphere blasting protection utilities support method, comprise the explosion quilt that junked tire makes, described method for protecting support comprises: step one, makes explosion quilt, is coated on explosion medicine hole with the explosion that waste rubber tire makes; Step 2, explosion is adopted the expansion bolt lengthened to anchor into lithosphere by surrounding, uses resilient brace to be connected and all can only accomplish security protection between expansion bolt with explosion quilt.Although above-mentioned two patents solve blasting safety protection problem, how to take into account dust-proof above, be also weak.This needs to propose new technical scheme and solves.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aim to provide one can dust-proof, can effectively protect again; Structure is simple, material is easy to get, light and easy construction, applied range, the demolition blasting flexible dustproof protection network of the dust-proof protection of different-effect can be realized.
The implementation of the utility model object is, demolition blasting flexible dustproof protection network, accompanies spongy layer between fixed network and protection network, and fixed network, protection network and spongy layer are sewed together by loop bonding line; Or binding wire in several some position by fixed network, protection network together with spongy layer colligation.
The utility model is flexible protection systems, and protection network, sponge all have the function absorbing blasting impact energy, can realize all standing but not totally enclosed protection to demolition blasting; Protection network can realize repeatedly using, cost-saving; Utilize the water droplets that water-absorbing sponge produces under blasting impact breaks effect, the effective control to blasting dust can be realized; Due to the material of sponge and thickness adjustable, during use, the distance in preventing dust protecting wire net and big gun hole is adjustable, and the explosion that can realize different-effect is dust-proof.
The utility model structure is simple, material is easy to get, light and easy construction, applied range.
Accompanying drawing explanation
Fig. 1 is the utility model generalized section.
Detailed description of the invention
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1, between fixed network 1 and protection network 3, accompany spongy layer 2, loop bonding line 4 by fixed network 1, protection network 3 and between spongy layer 2 be sewed together; Or by binding wire in several some position by fixed network 1, protection network 3 together with spongy layer 2 colligation.
The uniform spongy layer 2 of thickness is accompanied between fixed network 1 and protection network 3.
Tape edge line 2 adopts iron wire or macromolecular material silk thread.
Fixed network 1 adopts individual layer wire netting or plastic wire, mesh 2-6cm.Spongy layer 2 adopts foamed plastic or cellular rubber, as PU sponge.The thick 2-10cm of spongy layer 2.
Described protection network 3 is single layer of wires netting, steel wire or wire netting.Described protection network 3 can also adopt one deck wire netting or steel wire to add layer of steel wire netting.
In demolition blasting engineering, use the utility model, the utility model covers on the building of demolition blasting.During covering, fixed network 1 under, protection network 3 is upper; Subsequently the utility model corner or four limits are anchored at ground; Sprinkle water on the utility model again, spongy layer 2 is absorbed water saturated.After detonating, the moisture in spongy layer 2 is atomized by Blasting shock wave, can controlled blasting airborne dust well; Meanwhile, slungshot is also all tackled by the utility model.
Protection network of the present utility model can realize repeatedly using, cost-saving; Material and the thickness of sponge are adjustable, and during use, the distance in preventing dust protecting wire net and big gun hole is adjustable, and the explosion that can realize different-effect is dust-proof.
