Abstract
The invention discloses a detonation protection device for a shear wall. The detonation protection device comprises at least one mesh rubber layer. Each mesh rubber layer is provided with a plurality of rope binding sets used for bundling and covering mesh rubber to a shear wall face. Compared with the existing situation that a bed straw mattress is hung on a shear wall to protect detonation flying stone, the detonation protection device can well prevent detonation flying stone from being generated, hurt to surrounding people and property losses are controlled or reduced, and accidents are reduced.
Description
Technical field
The invention belongs to technical field of structural engineering, be specifically related to a kind of Blasting of shear wall preventer.
Background technology
Explosion (blasting) be utilize explosive produced compression of blast in empty gas and water, soil stone medium or object, loosen, destroy, throwing and lethal effect, a special kind of skill accomplished the end in view.Medicated bag or powder charge be explosion time in soil stone medium or works, make soil stone medium or works produce compress, deform, destroy, the loose and phenomenon of throwing, be mainly used in earth and rock works, and metal building thing and the dismounting etc. of structures.
It is often accompanied by blasting flyrock when the shear wall of tall and big construction building is carried out explosion, for avoiding blasting flyrock to cause the injury of periphery personnel's life and damage of facilities, therefore shear wall must be protected during explosion.In the prior art, general construction process is: after blast hole projectile filling, filling, race's connection are practiced shooting, hanging a straw mattress on shear wall, this kind of means of defence is fairly simple, prevents blasting flyrock effect poor, and blasting flyrock causes other danger destroyed higher.
Summary of the invention
In order to solve problem of the prior art, the invention provides a kind of Blasting of shear wall preventer, it is possible to well prevent blasting flyrock from causing periphery personnel injury and the loss of property..
The technical scheme is that a kind of Blasting of shear wall preventer, including at least one of which netted rubber layer, this netted rubber layer be provided with many for netted rubber being bundled the tied rope group being covered on shearing metope.
After blast hole projectile filling, filling, race's connection are practiced shooting, being vertically laid on shear wall to be blasted by netted rubber layer, and be passed through the through hole offered on shear wall by tied rope, bundle netted rubber layer, it is therefore prevented that dispersing of blasting flyrock, protection effect is good.
As preferably, described netted rubber layer is 2 ~ 4 layers.
As preferably, described netted rubber layer is 2 layers.
As preferably, described netted rubber layer is that honeycomb is netted.
As preferably, described tied rope group is evenly arranged along the week edge of netted rubber layer.
As preferably, described tied rope group is two steel wire ropes being arranged symmetrically with.
As preferably, described tied rope group is four groups, and four groups of tied rope groups are square.
Compared with prior art, beneficial effects of the present invention is embodied in:
The present invention hangs the protection to blasting flyrock of the straw mattress relative to existing on shear wall, it is possible to well prevent the generation of blasting flyrock, controls or decreases periphery personnel injury and property loss, decreases the generation of accident.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is present invention structural representation when being applied to Blasting of shear wall.
Fig. 3 is the lateral structural representation of Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiments of the invention: such as Fig. 1, shown in Fig. 2 and Fig. 3, Guizhou Province's Maotai Zhen Maotai clock tower blasting and dismantling engineering shear wall drillhole blasting, the big gun hole offered on shear wall, it is filled with #32 emulsion 5 bottom described big gun hole, self emulsifying explosive 5 end face loads sand cement admixture 6 to aperture, big gun hole 2, sand cement admixture 6 is grade cement identical with shear wall, and 3/5～2/3 that mixture fill depth is big gun hole 2 degree of depth, in big gun hole 2 powder charge, filling, after race's connection is practiced shooting, netted rubber layer 1 is vertically laid on shear wall to be blasted, and the through hole offered on shear wall it is passed through with steel wire rope 4, netted rubber layer is bundled, through hole distance up and down is 160cm.
In the present invention, netted rubber layer 1 is netted in honeycomb, and tied rope group 4 is evenly arranged along the week edge of netted rubber layer, and tied rope group 4 is two steel wire ropes being arranged symmetrically with.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
