Abstract
The utility model provides an annular energy cumulating groove type flat bottom blasting explosive bag and relates to a blasting charge structure. The bottom of a lower shell is provided with a protective plate, an annular energy cumulating explosive type shield is placed on the protective plate and filled with explosive that is provided with an upper shell; a detonator hole is arranged between the explosive and the upper shell. While blasting a rock soil protective layer for excavation, the energy cumulating blasting effect of the explosive is utilized to form a horizontal crevice surface, protect reserved bed rock and control the excavation quality of a basis horizontal foundation surface. Simultaneously, according to the blasting requirement of construction sites, with reference to geological conditions and in combination with blasting technology, and the interval of blast holes can be reasonably adjusted and arranged, thus achieving the effects of reducing the number of drill holes, improving the operation efficiency and reducing production cost. Generally, during the excavation process of rock soil horizontal foundation surface, a proper protective layer is reserved on the foundation surface. When the thickness of the protective layer is certain, the energy cumulating explosive bag arranged at the bottom of the hole can also be used as a detonating explosive bag directly.
Description
Technical field
The utility model relates to a kind of blast charging structure, mainly is used in the foundation level foundation plane excavation of ground blasting engineering, the flat explosion cartridge bag of a kind of annular cumulative grooved in the levelling of the land construction.
Background technology
In the modern project construction, very high requirement has been proposed foundation excavation.Different operating objects such as for example flat construction, slope construction, construction foundation working are when the job site is subjected to geological conditions, orographic condition constraint, in the time of must taking the blasting method construction.Out break, concussion of blasting that foundation plane is reserved protection, the control foundation plane physical dimension of basement rock may all be the different factors that influence explosion design, blasting construction process to influence of other structures or the like.Simultaneously, blasting boreholes equipment, drilling tool, big gun hole method for arranging, the super dark coefficient in big gun hole or the like all can influence the excavation quality of foundation plane.In slope construction, the foundation trench construction, can adopt this construction method of presplit blasting, basement rock is reserved in protection, controls the excavation quality of basic vertical plane.And in the Blasting Excavation on base water plane, be subjected to the restriction of rig, perforation facility, and making that the difficulty of horizontal direction boring is very big, efficient is not high yet.Control the excavation quality of horizontal foundation plane, the physical dimension that guarantees the excavation plane, protection reservation basement rock, all blasting scheme, blasting technology have been proposed very high requirement.When constructing all kinds of foundation level foundation plane with blasting method, be subjected to the influence of all kinds of factors such as rig, perforation drilling tool, big gun hole arrangement form, blasting method, blasting technology, orographic condition, construction cost, difficulty of construction is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides the flat explosion cartridge bag of a kind of annular cumulative grooved, can adopt vertical drilling tool construction blasting hole, then with the blasting method all kinds of foundation level foundation planes of constructing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the flat explosion cartridge bag of a kind of annular cumulative grooved, the lower house bottom is provided with backplate, be placed with annular cumulative cavity liner on the backplate, be filled with explosive in the annular cumulative cavity liner, explosive is provided with upper shell, is provided with the detonator hole in the middle of explosive and the upper shell.
Described annular cumulative cavity liner is a steel, axial cross section be "〉＜" shape.
The flat explosion cartridge bag of a kind of annular cumulative grooved that the utility model provides, by adopting the annular cumulative cavity liner of steel, when detonator detonates in the cartridge bag central whole, high pressure, at a high speed, high-octane energy-gathering jetting will cut, the splitting rock mass, make rock mass produce the crack, the gases at high pressure that blast produces impel fracture propagation, extension, will reserve formation horizontal fracture face on the basement rock after the cartridge bag explosion.The cartridge bag of annular cumulative cavity liner is housed, promptly can forms horizontal foundation plane in flakes according to some big guns hole of explosion designing requirement setting.Wooden backplate faces down, and can normally lay this blast hole explosive according to the explosion design on the cumulative cartridge bag.
The beneficial effects of the utility model are can utilize the CUMULATIVE BLASTING effect of explosive to form the horizontal fracture face in ground protective layer Blasting Excavation, protection reservation basement rock, control foundation level foundation plane excavation quality.According to job site explosion requirement,, in conjunction with blasting technology, can rationally adjust, arrange borehole spacing simultaneously, reach the effect that reduces drilling hole amount, improves operating efficiency, reduces production costs with reference to geological conditions.The horizontal foundation plane excavation of ground, one remains with suitable protective layer on foundation plane in digging process, and under the certain situation of protective layer thickness, the cumulative cartridge bag that the hole base fabric is put also can directly use as igniting primer.
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 a vertical view of the present utility model.
The specific embodiment
In Fig. 1, Fig. 2, the flat explosion cartridge bag of a kind of annular cumulative grooved, lower house 5 bottoms are provided with backplate 6, be placed with annular cumulative cavity liner 4 on the backplate 6, be filled with explosive 1 in the annular cumulative cavity liner 4, explosive 1 is provided with upper shell 3, is provided with detonator hole 2 in the middle of explosive 1 and the upper shell 3.
Described annular cumulative cavity liner 4 is a steel, axial cross section be upper and lower end "〉of dwindling towards the centre＜" shape.
In the lower house 5 of plastic material, insert wooden backplate 6 earlier, put into the annular cumulative cavity liner 4 of steel again, in the formed cavity, put into the explosive 1 of explosion designing requirement, compacting, floating, the detonator hole 2 of placing detonator is reserved at explosive 1 center, build the upper shell 3 of plastic material, also leave detonator hole 2 on the upper shell 3, use adhesive tape that upper and lower casing parting place is sealed.
The job site is according to the explosion designing requirement, the finishing drilling big gun hole of acceptance(check).Detonator is embedded cartridge bag detonator hole 2, and one of the wooden backplate 6 of cartridge bag faces down, and sends into reposefully at the bottom of the hole, detonator is linked payment to a porter draw the aperture, can normally lay this blast hole explosive according to the explosion design on the horizontally disposed cartridge bag.Carry out the big gun hole plug according to explosion design or routine, bursting work is implemented in the explosion networking.When integral body is detonated, high pressure, at a high speed, high-octane energy-gathering jetting will cut, the splitting rock mass, make rock mass produce the crack, the gases at high pressure that blast produces impel fracture propagation, extension, will form the horizontal fracture face on the basement rock reserving after the cartridge bag explosion.
The horizontal foundation plane excavation of ground, one remains with suitable protective layer on foundation plane in digging process, and under the certain situation of protective layer thickness, the cumulative cartridge bag that the hole base fabric is put also can directly use as igniting primer.
