Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment: one kind closing on high-voltage line mining blasting safeguard structure, as shown in Figure 1, including top of the slope 1 and slope foot 11, slope
Top 1 is equipped with several support stones 12, and support stone 12 is located in burst region, and is equipped in supporting block for covering explosion
The covering in region；Covering includes the double-deck bamboo sheathing 13 being arranged on support stone 12, the glue being laid in the double-deck bamboo sheathing 13
Skin 14, the wire netting 15 being arranged on rubber 14 and several sandbags 16 being covered on wire netting 15；When explosive charge, explosion
Air-flow between the double-deck bamboo sheathing 13 and ground in gap from being discharged, and the slungshot that explosion generates then is covered by blocking and decaying, reduces
The case where rubble flies out outward, the high voltage iron tower 19 under slope foot 11 is smashed, and reduce high voltage iron tower 19 damage and
Give surrounding resident life bring adverse effect.
As shown in Figure 1, the double-deck bamboo sheathing 13, rubber 14, wire netting 15 and sandbag 16 are cascaded by thin wire 18, make
Covering is linked to be an entirety and enhances the protection effect of covering.
As shown in Figure 1, further, slope foot 11 is equipped with vertical bamboo pole towards the side of top of the slope 1 in high voltage iron tower 19 and arranges
Frame 17(such as Fig. 2), the interception to the stone for flying to high voltage iron tower 19 is played, simultaneously because framed bent is compiled in length and breadth using bamboo pole
It knits, it is at low cost, effect is good.
As shown in Figure 1, offering Damping ditch 2 at slope foot 11, Damping ditch 2 is located at bamboo pole framed bent 17 away from high voltage iron tower 19
Side, the width and depth of Damping ditch 2 are all larger than 4m, guarantee the capacity of Damping ditch 2；In practical blasting process, in slopes
It separates and tumbles to slope foot 11 with slopes under the impact that part stone may explode, to bring prestige to high voltage iron tower 19
The side of body, and 2 one side of Damping ditch being arranged can be such that the stone tumbled falls into Damping ditch 2, on the other hand cut off high voltage iron tower 19
Vibration propagation between blasting face safeguards the stability of high voltage iron tower 19.
As shown in Figure 1, for full rock land band, operator can open up Damping ditch 2, the intensive shock relieve vent of arrangement or with static
Broken to form criss-cross crackle, to block the propagation of attenuation of seismic waves, Damping ditch 2, shock relieve vent, absorbing joint are in distance protection
10~20 meters of position settings in front of object.
As shown in Figure 1, slope foot 11 is additionally provided with along the distribution of 2 length direction of Damping ditch between bamboo pole framed bent 17 and Damping ditch 2
Masonry dam 21 is blocked, masonry dam 21 is blocked and is mainly responsible for cooperation with Damping ditch 2, stops the stone for being directed across Damping ditch 2；Simultaneously because bamboo
Pole framed bent 17 is located at high voltage iron tower 19 and blocks between masonry dam 21, blocks masonry dam 21 and also acts protective effect to bamboo pole framed bent 17,
And be arranged in slopes compared to by bamboo pole framed bent 17, the position of bamboo pole framed bent 17 also reduces the directly quilt of bamboo pole framed bent 17 at this time
Rolling Stone pound to a possibility that.
As shown in Figure 1, blocking 21 height of masonry dam is greater than 4m, effective interception when blocking masonry dam 21 to large scale conducive to raising,
The gradient for blocking masonry dam 21 is greater than 60o, reduce it is too small and make the base for blocking masonry dam 21 wider due to blocking 21 gradient of masonry dam, thus
The case where 21 materials of masonry dam are blocked in increase.
As shown in Figure 1, there are native rock layers 3 on the brace foundation of high voltage iron tower 19, it is conducive to increase by 19 brace foundation of high voltage iron tower
Length of embedment, and then improve stability of the high voltage iron tower 19 under explosion vibration.
As shown in Figure 1, in addition, concrete 31 has also been poured around the brace foundation of high voltage iron tower 19, by increasing high pressure
The volume of 19 brace foundation of steel tower, to achieve the purpose that further enhance iron tower stability.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
