Abstract
The utility model relates to a bidirectional energy gathering slot type explosive bag, including explosive housing. The explosive is place in the housing, the explosive bag is in the shape of butterfly with a primacord slot at the central portion, the primacord is placed into the primacord slot. Convex slots are provided in the explosive housing, and an energy gathering slot is fixed inside the primacord slot through the convex slots. A centralizer is provided outside the explosive housing. According to the bidirectional energy gathering slot type explosive bag of the utility model, centralizers are adopted for the entire explosive bag in sections along the length direction, so that the explosive bag can be kept at the central position of the blast hole. The energy gathering slot can have the effect of energy gathering. Under the action of the injection directivity, cutting and splitting of the air blade, designed interval between two adjacent pre-splitting explosive pores meets the requirements of the explosion, the range of the geological adaptation condition is enlarged. Therefore, the number of pores can be reduced, the operation efficiency can be improved, the operation time can be shortened and the effect of cost reduction is achieved.
Description
Technical field
The utility model relates to a kind of demolition set, is specifically related to a kind of two-way cumulative grooved explosion cartridge bag that utilizes the explosive blasting Mohaupt effect.
Background technology
At present, geotechnical engineering construction adopts this construction technology of explosion presplitting usually, and the integrality of rock is reserved in protection, reduces the influence of concussion of blasting to the side slope rear wall.Generally be according to on-the-spot geological conditions, according to a determining deviation design arrangement big gun hole, this process form of coupling charging, segmentation control dose, explosion in advance forms continuous crack. and stop the conduction of later stage concussion of blasting ripple, reach the effect that rock mass is reserved in protection.The quality of blasting quality depends primarily on the drilling quality in big gun hole, the spacing in big gun hole, blasting technique three big factors.Can not protect the reservation rock in the blasting process of existing medicine place, also be unfavorable for forming continuous cracking face.
Summary of the invention
The purpose of this utility model is to provide a kind of when the whole igniting primer of primacord, can produce high pressure, at a high speed, high-octane jet is splitting, cutting rock mass, impels fracture extension, expansion, forms the two-way cumulative grooved explosion cartridge bag of continuous cracking face.
The purpose of this utility model is achieved in that a kind of two-way cumulative grooved explosion cartridge bag, comprise the cartridge bag housing, explosive places in the cartridge bag housing, the cartridge bag housing is the butterfly that the middle part has the primacord groove, primacord places the primacord groove, be provided with tongue in the cartridge bag housing, troughs for collecting energy is fixed in the cartridge bag housing by tongue.The cartridge bag housing is provided with centralizer outward.
The two-way cumulative grooved explosion cartridge bag that the utility model provides, centralizer has been used in segmentation on the cartridge bag entire length, can keep cartridge bag to be in center, big gun hole preferably.Under the acting in conjunction of not coupling charging form cartridge bag, CUMULATIVE BLASTING jet, to the formation of slope rock mass precracking, it is obvious that the effect of rock is reserved in protection.Simultaneously, cumulative action by troughs for collecting energy, jet direction in explosion, under the cutting of gas sword, the slabbing action, make the boring design pitch in adjacent two presplitting big gun holes enlarge the geology condition of compatibility according to the explosion requirement, can reduce drilling hole amount like this, improve operating efficiency, shorten the activity duration, reach the effect that reduces cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A place enlarged drawing among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of two-way cumulative grooved explosion cartridge bag, comprise cartridge bag housing 1, explosive 3 places in the cartridge bag housing 1, cartridge bag housing 1 has the butterfly of primacord groove 6 for the middle part, primacord 4 places primacord groove 6, is provided with tongue 7 in the cartridge bag housing 1, and troughs for collecting energy 2 is fixed in the cartridge bag housing 1 by tongue 7.The cartridge bag housing 1 outer centralizer 5 that is provided with.
When the utility model uses, primacord 4 is embedded in the primacord groove 6.Cartridge bag segmentation place is buckled the plastics adapter sleeve and is fixed.Buckle centralizer 5 at a certain distance respectively, make cartridge bag and blasthole hole wall 8 keep centering.Keep cartridge bag two troughs for collecting energy 2 line directions consistent, steadily send at the bottom of the hole with explosion design precracking direction.The big gun hole plug, the explosion networking is carried out according to routine or explosion designing requirement, implements bursting work.
Claims (2)
1. two-way cumulative grooved explosion cartridge bag, comprise cartridge bag housing (1), explosive (3) places in the cartridge bag housing (1), it is characterized in that: cartridge bag housing (1) has the butterfly of primacord groove (6) for the middle part, primacord (4) places primacord groove (6), be provided with tongue (7) in the cartridge bag housing (1), troughs for collecting energy (2) is fixed in the cartridge bag housing (1) by tongue (7).
