Figure 11 illustrates another embodiment of dynamite container 10C.Dynamite container 10C comprises that first container 48 and that is formed for putting first compartment 12 of choke material 14 is formed for putting second container 50 of second compartment 16 of high energy material 18.Partition 22 between first and second compartment is the embolism form, and it has an axial hole, that the lead-in wire 42 of initiator 28 is worn and mistake.Initiator 28 is arranged within second container 50.The free end of second container 50 is sealed by the wallboard 26 that also is the embolism form.The opposite end of dynamite container 10C is sealed by end wallboard 24, and lead-in wire 42 passes this wallboard.In order to strengthen sealing/filling effect, first compartment 12, that is, container 48 is configured to can be out of shape when pressure puts on dynamite container 10C end wallboard 24 in the hole.This pressure can utilize pole to make firm by ramming or tamp by manpower and be applied.Pressure causes compartment 12 radially to expand outwardly and withstands hole wall portion.Can provide like this to grasp fully so that dynamite container 10C is fixed within the hole and can when igniting, do not penetrated, without any need for such as the excellent such external device (ED) of filling.In this case, dynamite container 10C act as a kind of auto-pack formula dynamite container.Can conceive, this effect is at minor diameter such as to arrive under the situation in hole of 18mm greatly will be the most remarkable.

Can form the line or the slit of some weakenings around compartment 12, so that strengthen its distortion and increase the possibility of its spalling when on end wallboard 24, applying compression stress.Distortion and spalling can be by with a kind of materials of easy deformation, such as thin-walled plastic or paper is made and further reinforcement.

First compartment, 16/ container 50 is an open-ended form of tubes, is made by a kind of rigid material, is making firm by ramming or its resistance to deformation during applying compression stress on the dynamite container 10C end 24.Such as, compartment 16 can be made by rigidity plastics, metal or a kind of composite.Compartment 16/ container 50 should be firm and more strong so that the high energy material after lighting forms pressure with high speed.Because the rising that is exceedingly fast of pressure itself causes the completing combustion reaction that is exceedingly fast of high energy material 18 again, so this point is favourable.Reaction is faster, and is littler in the variation of leaking in order to gas before finishing the work aspect destruction or fractured rock or other stiff materials.

Figure 12 illustrates another embodiment of dynamite container 10D.Dynamite container 10D is different from the shape that dynamite container 10C part only is the partition 22 between first compartment 12 and second compartment 16.In this embodiment, one is made in the end 58 of the partition 22 and second container 50.Aspect every other, dynamite container 10D is the same with the dynamite container 10C shown in Figure 11.

Figure 13 illustrates another embodiment of dynamite container 10E, and itself and dynamite container 10C shown in Figure 11 are similar, just has the wedging device of wedging cap 86 forms, and it is connected in the free end of first compartment 12.In use, wedging cap 86 act as the voussoir between dynamite container 10E outer peripheral surfaces and the hole sidewall.This can produce two kinds of effects.At first, it helps closed hole.Secondly, it act as during igniting and later on dynamite container 10E is held in the auto-pack effect of consequently strengthening dynamite container 10E within the hole.Cap 86 is furnished with a centre bore, the lead-in wire 42 wear and mistake.Wall portion or shirt rim 88 have tapering, so that increase at the thickness away from the direction of second compartment 16.When dynamite container 10G inserts a hole, exert pressure to it via cap 86.This forces cap 86 to be enclosed within the free end of compartment 12, and because the band tapering character of shirt rim 88 can make shirt rim 88 radially outwards open flare.Opening of shirt rim 88 can be strengthened by one or more vertical slit or battlements line are set on shirt rim 88.

Another embodiment of dynamite container 10F is shown among Figure 14.Dynamite container 10F is different from dynamite container 10E shown in Figure 3 and only is to replace flat end wallboard 24 with a frustoconical cap 24F.The top frustum 90 that cap 24F has, it converges on the direction away from first compartment 12.The end 92 of frustum 90 is furnished with a hole, and lead-in wire 42 extends and mistake.The opposite end configuration one of cap 24F is the short extension 94 of constant diameter basically, and it is fitted in the inboard and connection of first compartment, 12 upper ends 62 or is fixed on this upper end in other mode.Cap 24F is matched with herringbone cap 86 with impel cap 86 to recline internal surfaces of holes that dynamite container 10F was inserted and wedging and locking.

Figure 15 illustrates another embodiment of dynamite container 10G.This embodiment comprises second compartment 16 that is used to put first compartment 12 of energy absorption choke material 14 and is used to hold high energy material 18.Dynamite container 10G also comprises an edge cap 24F and a wedging cap 86, is similar to dynamite container 10F shown in Figure 14.First compartment 12 is formed by first container 48, and second compartment 16 is formed by second container 50.But, to be different from the difference of dynamite container 10F as follows for dynamite container 10G: the lower end 54 of container 50 forms compartment rather than utilizes an independent end wallboard or an embolism to be sealed by the lower end that is closed with monoblock type; And partition 22 is circular cone 96 forms, and itself constitutes the part of coupling 98 again, and this coupling is used for first container 48 is connected in second container 50.Coupling 98 can be regarded one section short tube as, and circular cone 96 is positioned at it.The sensing of circular cone 96 causes it to converge in the direction from first compartment, 12 to second compartments 16.Top the sentencing that one hole is formed in circular cone 96 allows lead-in wire 42 to pass through.One routine face flange or ring 100 are formed on the outside of coupling 98 around the substrate of circular cone 96.Flange 100 is that the adjacent both ends of first and second compartments 48,50 forms an abutment.

Can conceive, coupling 98 can be molded out of plastic a single-piece, though it can be made with several different elements that link together, such as circular cone 96 and flange 100 as an element, and two sections conllinear be connected in short tube on the opposite sides thereof of flange 100.Coupling 98 forms many functions, comprising: use a pressure plug as during the high energy material burning; During the high energy material burning, be out of shape and the sidewall of closed hole, leak from the hole thereby reduce gases at high pressure in a kind of mode that causes flange 100 radially outwards to stretch; Force the choke material 14 in circular cone 96 zones upwards to enter container 48, radially oppress the recline surface, inside of first compartment 12 of choke material 14 whereby, thereby and the first compartment 12 hole sidewall that reclines, further promoting to reduce gases at high pressure thus may be from the further leakage in hole; Supporting initiator 28 also makes it centering; Sealing initiator 28 and high energy material 18 make it avoid being present in moisture or other field trashes among the choke material 14; And support first and

second compartments

12,16.

Dynamite container 10 can be that diameter is made with multiple size.As mentioned above, dynamite container 10C-10G has the characteristic that can make their oneself fillings in the hole, if particularly be used for for example, on reach 18mm than minor diameter.Dynamite container 10 may be ideally suited in some contractors independently, and they have the small hand-held drilling tool as its main drilling equipment, such as a HILTI or a KANGO mallet bores or a hand-held Pneumatic immpacting mallet bores.Because this type of Hand driling tool all is the standard device of all explosion contractors,, adopt this dynamite container 10 not need any fund outside dynamite container 10 costs own to pay so be understandable that.Even so, larger-diameter dynamite container can be used for destruction or fractured rock or other stiff materials, and this moment, larger-diameter hole utilized track-mounted drill, Retractive leg churn or portable rig to be drilled to always.Because dynamite container 10 comprises all usually required materials, i.e. high energy material 16, choke material 18 and initiator 28 are so detonation velocity can be simplified and increase to the use of dynamite container 10.There is no need to keep separately the supply of high energy material, choke material and initiator, then respectively they are filled in the hole.

Since various embodiments of the present invention are at length illustrated, what will obviously easily see to those skilled in the art is, can make many modifications and changes and does not break away from basic inventive concept.Such as, it is the choke material of shot shape that choke material 14 major parts are drawn as, such as granule.But, also can comprise the choke material of other types, have viscosity with liquid and the slurries of shearing the physical property that increases such as those.Secondly, the upper end wallboard of dynamite container 10,10A is shown a plane wallboard 24 or a circular cone wallboard 60 always.But, this wallboard can be taked many other shapes, and such as recessed or protruding crooked wallboard, they can engage or cooperate the lower end of being processed into complementary shape of filling rod.Equally, the each several part of formation first and second compartments of dynamite container 10,10G needs not be and is made by same material.It is desirable to, second compartment of putting high energy material has the rigidity of resonable degree, so that the starting stage restriction high energy material that is detonating.On the other hand, preferably, first compartment ratio that puts choke material is easier to radially be out of shape, so that it can be urged and the hole sidewall that reclines increases sealing effectiveness.
