Description
Technical field
The present invention relates to Construction Technology field, a kind of blasthole for LARGE APERTURE STATIC IMAGING fractured rock is specifically related to
Blocking device.
Background technology
Static blasting have noiseless, without poison gas, it is without friction, without slungshot the features such as, so the construction method is some right
Blasting damage control require it is very strict in the case of obtained relatively broad application.
The principle of static blasting is chemically reacted for static breaking agent with water, and substantial amounts of heat is released in the process, and
Its volume rapid expanding.In general, under the conditions of free wxpansion, static breaking agent is after abundant hydration reaction, and volume can increase
Plus 2~4 times.If it is seated in closed blasthole, volumetric expansion process can produce very big pressure in blasthole, when this
Pressure will be crushed when being more than the intensity of surrounding medium.The bulbs of pressure of static breaking agent increase with the increase in aperture
Greatly, the pore diameter range more than current domestic comparison is generally 30~50mm.When being applied in the range of this, charge process compares
Simply, just can be with as long as medicament is loaded into blasthole, it is not necessary to take special measure, and most of disclosure satisfy that will
Ask.It is some it is special in the case of, in order to obtain the larger bulbs of pressure, larger aperture can be used.With the increase in aperture,
Expansion produces larger pressure and is easily caused punching.

Embodiment
The accompanying drawing for constituting the part of the application is used for providing a further understanding of the present invention, schematic reality of the invention
Apply example and its illustrate to be used to explain the present invention, do not constitute inappropriate limitation of the present invention.
Referring to Fig. 1~2, provided by the present invention for the multiple-row blasting device of LARGE APERTURE STATIC IMAGING fractured rock, including：For
The bottom 200 covered the top 100 of blasthole and stretched into blasthole, top 100 and bottom 200 are opened up in multiple insertions along its axial direction
In the breaking pin hole 110 of portion 100 and bottom 200, the insertion breaking pin hole 110 of safety plug 310；Bottom 200 is radially offered
Multiple firing pin empty rooms 340 for being used to accommodate firing pin 330, outer wall Shangrao of firing pin 330 sets striker spring 320, and one end of safety plug 310 is stretched
Enter the external part that firing pin 330 is connected in firing pin empty room 340 and compress striker spring 320.
Using the device, the punching problem of prevention blasthole can be efficiently realized, working security is improved.Apparatus structure letter
It is single, it is easy to use, suitable for engineering application.The shape on obvious top 100 and bottom 200 can be carried out according to the concrete shape of blasthole
Adjustment, such as can be the structures such as cylinder or rectangle.
It is preferred that, top 100 is made up of steel, aluminium alloy or plastics.
It is preferred that, bottom 200 is made up of steel, aluminium alloy or plastics.
It is preferred that, top 100 with diameter greater than blasthole diameter；The diameter of bottom 200 is less than blasthole diameter.
It is preferred that, breaking pin hole 110 and firing pin empty room 340 are correspondingly arranged 4~6.Set, can be optimal by this quantity
Anti- punching effect.
It is preferred that, the external part of firing pin 330 is tip.Using tip, firing pin 330 can be made to insert in the wall of blasthole side, so that
Increase its frictional force, improve protecting against shock effect.
Referring to Fig. 3, the device is when unused, the insertion breaking pin hole 110 of safety plug 310, and blocks firing pin 330, firing pin
Spring 320 is in compressive state.When in use, in the insertion of blocking device bottom 200 blasthole, top 100 covers blasthole.Pull out safety plug
310, firing pin 330 is out of hand, is ejected outward under the tension force effect of striker spring 320, withstands on blasthole wall.Due to striker spring
320 tension force is very big, and the head of firing pin 330 is more sharp, so blocking device produces larger frictional force with blasthole wall, from
And realize the purpose implemented quick blocking to blasthole, prevent punching from occurring.
Operating method：
The situation of firing pin 330, the safety position of safety plug 310 in the first step, inspection blocking device firing pin empty room 340, it is ensured that
Safety plug 310 blocks firing pin 330, and striker spring 320 is into compressive state；
Second step, to simply being cleared up around big gun blasthole portion, the bottom 200 of the present apparatus is inserted in blasthole, until
Untill the top 100 of the present apparatus covers big gun blasthole portion completely；
3rd step, safety plug 310 is extracted with hand successively, can hear " ding-dong " sound once, this is firing pin 330 in firing pin
The sound withstood under the tension force effect of spring 320 on blasthole wall；
4th step, after all safety plugs 310 are all extracted, grasps the top 100 of blocking device, and slightly rotates,
And gently moving up and down the present apparatus with hand, it is ensured that all firing pins 330 are contacted closely with blasthole wall completely.
Application example
Between 2015 to 2016 years, in build five innings in Changsha Rail Transit Line 3 first stage of the project Changsha Railway Station station foundation ditch
In work progress, in order to ensure the safe operation of Line 2 Metro, its structure both sides rock is intended using the construction of static blasting method.
In work progress, because part location rock is more hard, small-bore static blasting construction effect is not good, therefore employs heavy caliber
