Description
Technical field
This utility model relates to hydraulic pressure demolition technical field, is specially a kind of Tunnel Blasting charge constitution.
Background technology
Energy-conserving and environment-protective tunnel hydraulic pressure demolition technology has started to gradually try out and promote, a certain amount of by injecting in blast hole
Water, and utilize the gas expansion that emulsion produces, promote this stable medium of water to produce secondary attack in blast hole,
Form water wedge and carry out Rock cutting, produce more preferable fractured rock effect, reduce explosive specific charge to a certain extent, reduce fried
Medicine cost；Simultaneously because explosion causes water atomization, form water membrane at rock surface, serve the work reducing Blasting dust
With.But water filling difficulty in horizontal blasting hole is relatively big, complicated construction technique causes efficiency of construction low, and blasting quality is difficult to ensure.
Utility model content
It is to provide one to be applicable to horizontal blasting mouth for the problems referred to above the purpose of this utility model, and simple in construction,
Can have strong operability, can be effectively improved the Tunnel Blasting charge constitution of construction quality and efficiency.Technical scheme is as follows:
A kind of Tunnel Blasting charge constitution, including hole bottom water bag, seals water bag, rock emulsion explosive bag and leads quick-fried parts；
Hole bottom water bag is arranged at the bottom, hole in big gun hole, and sealing water bag is arranged at for blocking inside the stemming in aperture, multiple rock emulsifyings
The blasting charge is arranged between hole bottom water bag and sealing water bag；Lead quick-fried parts through stemming, sealing water bag and rock emulsion explosive bag
It is fixedly installed near big gun axially bored line.
Further, when described big gun hole is periphery hole, each rock emulsion explosive parlor is spaced apart by being spaced water bag.
Further, described interval water bag is the water bag of single round bar shaped.
Further, described in breaking hole, lead the detonator that quick-fried parts are band detonator, periphery hole leads quick-fried parts
For primacord.
Further, described hole bottom water bag is the water bag of single round bar shaped, and sealing water bag is double joint circle bar shaped water bag.
The beneficial effects of the utility model are: this utility model is applicable to horizontal blasting hole, can be effectively improved blasting efficiency,
Reducing explosive specific charge, after explosion, the water in water bag can play atomized dust settling effect, is substantially reduced the dust pollution to environment；And
And also there is simple in construction, can have strong operability, be not take up Blasting Excavation activity time, improve effect, the advantage such as cheap.
Accompanying drawing explanation
Fig. 1 is breaking hole charge constitution schematic diagram.
Fig. 2 is periphery hole charge constitution schematic diagram.
In figure: the bottom water bag of 1-hole；2-leads quick-fried parts；3-rock emulsion explosive bag；4-stemming；5-seals water bag；6-is spaced
Water bag.
Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
Tunnel piercing hydraulic pressure demolition is in sides such as undermining type, borehole layout, quantity, the degree of depth, firing order and time intervals
Face is as tunnel conventional blasting method, except that different in terms of blashole charge amount and charge constitution.The present embodiment
A kind of Tunnel Blasting charge constitution, including hole bottom water bag 1, seals water bag 5, rock emulsion explosive bag 3 and leads quick-fried parts 2；At the bottom of hole
Water bag 1 is arranged at the bottom, hole in big gun hole, and sealing water bag 5 is arranged at for blocking inside the stemming 4 in aperture, and multiple rock emulsifyings are exploded
Medicated bag 3 is arranged between hole bottom water bag 1 and sealing water bag 5；Lead quick-fried parts 2 to explode through stemming 4, sealing water bag 5 and rock emulsifying
Medicated bag 3 is fixedly installed near big gun axially bored line.Owing to energy is in Incoercibility to water of the shock wave of water transmission, make blast
Energy in Water transport to country rock almost without loss, meanwhile, " water wedge " effect that water produces under explosion gas expansion,
Being conducive to catalase, the water in borehole can play atomized dust settling effect, is substantially reduced the dust pollution to environment.
The water bag that hole bottom water bag 1 is single round bar shaped of the present embodiment, sealing water bag 5 is double joint circle bar shaped water bag.Avalanche
Leading, in hole, the detonator that quick-fried parts 2 are band detonator, the quick-fried parts 2 of leading in periphery hole are primacord.
Concrete, breaking hole single hole powder charge process is: the water bag of the round bar shaped of hole bottom plug one, middle part is filled many continuously
Individual rock emulsion explosive bag, orifice position is filled in two round bar shaped water bags the most continuously, is finally carried out aperture envelope with the stemming 4 of column
Stifled.
Periphery hole single hole powder charge process is: use primacord interval to connect explosive, by being spaced by wall scroll circle bar shaped water bag
Explosive colligation in load hole, is spaced apart by interval water bag 6 between the most each rock emulsion explosive bag 3 in bamboo cane, and aperture is with column
Stemming 4 blocks.
This Tunnel Blasting charge constitution have simple in construction, can have strong operability, be not take up Blasting Excavation activity time, improve merit
Effect, the advantage such as cheap.
