Description
Technical field
The present invention relates to blasting engineering technical fields, particularly relate to a kind of raising water-filling drilling abatement blasting vibration
The device and construction method of effect.
Background technology
Blasting Excavation has high efficiency outstanding, is the engineering rock mass such as current China's water power, transport development and mining
Main excavation method.However, while explosive charge is completed rock-mass relaxing, excavated, adjoint strong blasting vibration is often
Surrounding building can be damaged.When burst region and surrounding building are closer, it is general using burst region with protected
Damping ditch is excavated between shield building or the mode that number arranges shock relieve vent is set, to reduce conduction as possible extremely by protection building
Blasting vibration intensity protects the safety of the building.
As shown in Figure 1, drilling in burst region and by two emptying of setting between protection building, due to being empty in drilling
Gas almost can not directly conduct attenuation of seismic waves (playing the role of blocking propagation), and attenuation of seismic waves can only be at borehole wall interface
Reflection, diffraction occurs, and then interfering with each other and consuming for seismic wave is formed between more drillings, to further decreasing explosion
The oscillation intensity of seismic wave.The empty drilling of such arrangement, the referred to as shock relieve vent of blasting vibration.
However engineering in practice, due to rain leakage or recharge ground water, often portion in above-mentioned shock relieve vent
Water-filling is divided even to be filled with water.Since the conduct vibrations characteristic of water and air is entirely different, in the borehole in the case of water-filling, ground
Seismic wave can be directly conducted to the hole wall other side (direct transmissive) in the side of borehole wall；Simultaneously because transmissive portion increases
Add, the reflection, diffraction that seismic wave occurs at borehole wall interface is greatly reduced, and can not also be formed between more drillings effective dry
It disturbs and consumes.
Therefore, in the case of water-filling in shock relieve vent, blocking, the consumption of attenuation of seismic waves drop in shock relieve vent significantly
It is low, can not play the role of design effectiveness in vibration suppression and, cause the damping to involve great expense drilling to waste, while without abatement
Strong blasting vibration is also easier to lead to be protected the damage and destruction of building.
Invention content
For in current practical blasting engineering glissando, due to rain leakage or recharge ground water, shock relieve vent is caused to fill
The technical issues of damping effect after water substantially reduces, the purpose of the present invention is to provide a kind of raising water-filling shock relieve vent abatement is quick-fried
The device and construction method of broken vibrating effect, can be effectively ensured the shock relieve vent after water-filling still and can play due design and subtract
Shake effect and effect.
To achieve the above object, the technical solution that the present invention takes is：
A kind of device improving water-filling shock relieve vent abatement blasting vibration effect, including for being mounted in water-filling shock relieve vent
Branched damping packing element, each damping packing element include waterproof outer rubber tube and internal layer granular media packing material, the internal layer

(2) it into the shock relieve vent of above-mentioned water-filling, then is put into second by second damping packing element connection cord suspention and subtracts
Packing element is shaken, at this point, under the gravity of second damping packing element, first damping packing element positioned at lower part is compressed, directly
Diameter is thicker, until consistent with the aperture of the shock relieve vent so that and the gap between damping packing element and shock relieve vent hole wall is eliminated, into
And all water being filled in hole wall gap are extruded；
(3) repeat the above steps the process of (2), continues up and is sequentially placed into several dampings in the shock relieve vent for stating single water-filling
Packing element stops until a damping packing element being finally putting into reaches at the aperture of shock relieve vent, is now placed in all in the shock relieve vent
Water body is just all expelled from.
Compared with prior art, it is an advantage of the invention that：(1) outer layer of damping packing element is made of soft rubber, can be risen
To good cushioning effect；(2) internal layer of damping packing element is particles filled with common engineering discrete material, it can not only play slow
It rushes earthquake and involves the effect for absorbing seismic wave vibration, and is of low cost；(3) by the way that damping packing element global density to be designed as comparing
Water density is big, and damping packing element can be made integrally to sink under the effect of gravity in water-filled shock relieve vent, convenient in discharge shock relieve vent
Water body；It (4), can be in the weight of top damping packing element by the free state diameter design of damping packing element at the aperture for being slightly less than shock relieve vent
Under force effect, realize that compression, diameter are thicker, until it is consistent with boring aperture, to complete gap between damping packing element and hole wall
Eliminate and squeeze out all water；(4) damping packing element generally shock insulation unit is put into damping packing element in shock relieve vent and can reach and subtracting
It shakes in hole full of the damping effect that air is the same；(5) damping packing element is recyclable, reuses, can profit after the completion of blast working
The damping packing element in shock relieve vent is taken out with cord, will not be had any impact to architectural environment.
