Description
Technical field
It the utility model is related to subway foundation pit borehole blasting security fields, more particularly to multiple anti-slungshot in a kind of subway foundation pit
Safety device.
Background technology
Because subway is largely built inside each city, the melt pit of some firm country rocks needs to use the means of explosion to enter
Row cleaning, the region of some construction of subway is in the bustling location in city, explosion generation very near apart from the building of surrounding and traffic
Slungshot, soil block due to itself speed it is very fast, once be splashed on road or building, it is easy to cause personal injury or
Person's structure damage, bring the loss of personnel and property.This be in subway work caused new problem, it is necessary to improve to it
And protection, the loss for avoiding these from not occurring.
The content of the invention
The purpose of this utility model is to overcome weak point of the prior art, there is provided multiple in a kind of subway foundation pit
The safety device of anti-slungshot.In order to achieve the above object, the utility model is achieved through the following technical solutions：
The safety device of multiple anti-slungshot in a kind of subway foundation pit, the safety device include ground shield
Layer, middle level overcoat and top layer overcoat, ground shield layer include being arranged on ground rubber cord, the rubber curtain above blasthole
The sandbag set above the bamboo splint and bamboo splint set above cloth, the rubber cord and bamboo splint are fixed on by chock
On ground.
Further, the middle level protection mainly includes the double-deck bamboo splint set on bracing members and bracing members；The steel
Support is arranged at pit foundation abutment wall.
Further, is rope is fixedly installed in the top layer overcoat in foundation ditch top edge, and is fixedly installed on rope
There is safety net.
Further, the rubber cord is made up of 2~3 layers of junked tire.
Further, the coverage of rubber cord and the bamboo splint composition will exceed more than blasting body edge 1m.
The beneficial effects of the utility model：
The safety device of multiple anti-slungshot in subway foundation pit of the present utility model, using multi-layered devices by subway foundation pit
Slungshot caused by explosion etc. is intercepted, and avoids its personnel to surrounding, traffic and building from producing threat, protects surrounding
The safety of environment, avoid unnecessary loss.
Utility model is described in detail with reference to the accompanying drawings and examples.

Embodiment
As shown in figure 1, in a kind of subway foundation pit multiple anti-slungshot safety device, the safety device includes
Ground shield layer, middle level overcoat and top layer overcoat, ground shield layer include being arranged at the rubber curtain of the top of blasthole 4 on ground
The sandbag 8 that the bamboo splint 6 and the top of bamboo splint 6 that cloth 5, the top of rubber cord 5 are set are set, the rubber cord 5 and bamboo splint
6 are fixed on the ground by chock 7.The rubber cord 5 is made up of 2~3 layers of junked tire.The rubber cord 5 and bamboo
The coverage that clamping plate 6 forms will exceed more than blasting body edge 1m.
As shown in Fig. 2 the middle level protection mainly includes the double-deck bamboo splint 11 set on bracing members 10 and bracing members 10；
The bracing members 10 are arranged at pit foundation abutment wall 9.
As shown in figure 3, the top layer overcoat is that rope 2 is fixedly installed in foundation ditch top edge 1, and it is fixed on rope 2
It is provided with safety net 3.
During explosion, the top of blasthole 4 is blocked by rubber cord 5, and there are a bamboo splint 6 and sandbag 8 of compacting in top, is produced during explosion
Seismic wave be trapped in blasthole 4, slungshot caused by explosion and soil block touch bamboo pressing plate 6 first, and sandbag 8 has aggravated bamboo pressing plate
6 weight, slungshot and soil block is rebounded and is gone back, be not in the splashing of large area, high degree is reduced caused by explosion
Harmful effect.After thering is slungshot, soil block to cross ground shield, middle level protection can be run into, middle level protection is by double-deck bamboo splint
11, if also slungshot can cross this layer of protection, it be able to will substantially be touched all to bounce-backs such as blasting flyrocks here
Interception to top layer by safety net 3, all slungshots can substantially be stopped, will not be because of traffic of the slungshot to surrounding, people
Body safety and building cause damage, and protect the safety and environment of surrounding.
