The spacer is characterized by comprising an inner barrel and an outer barrel, wherein arc-shaped grooves are symmetrically arranged in the outer surface of the inner barrel; the outer barrel is arranged on the outer surface of the inner barrel in a sleeving manner and is concentric with the inner barrel; crushed straw mixed with binder is filled between the outer barrel and the inner barrel; the upper part of the inner barrel is higher than the outer barrel; the lower part of the inner barrel is contracted into the outer barrel. The spacer disclosed by the utility model has the advantages that the radial uniform energy-gathered non-coupling spaced charging in a blast hole can be realized; the continuity of the spacer in the axial direction of the blast hole is guaranteed and leakage of the charging at the joint can be prevented by adopting a trapezoidal connection structure; the spacer is manufactured by using the crushed crop straw, so that the spacer is extensive in source, economic, free of pollution, simple in processing and manufacturing, and convenient in field use.
Description
Technical field
The utility model relates to mining and Geotechnical Engineering Blasting excavation powder charge utensil, especially a kind of environment-friendly type bilinearity cumulative explosive loading spacer that is not coupled.
Background technology
In side slope pre split explosion in large-scale hydroelectric project slope excavating, the presplit blasting of urban construction ground excavation of foundation pit, large surface mine exploitation by helping presplit blasting etc. all to have some common requirements; that is: alleviate explosive opposite side and help the integrity that slope is bad, edge protection is helped; reduce explosion earthquake intensity of wave simultaneously, alleviate the flutter failure of explosion to side slope or Adjacent Buildings, alleviate big gun hole excessive pulverizing around etc.For realizing these requirements, what in engineering, often adopt is by shifting to an earlier date explosion presplit blasting hole, forms and effectively connects precracking, reduces the damage of main blast hole explosion to side slope thereby reach.And the technical way of realizing presplit blasting is coupling charging technology not, tradition not coupling charging is divided into and is not axially coupled and is not radially coupled, and axially coupling charging, by realizing with axial powder charge spacer, and is not applied in explosion.Realize by reducing cartridge size and be not radially coupled, because the position of powder column in big gun hole is uncertain, so this loading method can not be controlled Explosive Energy and mainly put on precracking formation direction, may cause hole wall to destroy in uncertain direction again, waste explosive.Thereby invent a kind of cumulative explosive loading spacer that is not coupled and there is industrial prospect clearly.
Summary of the invention
The purpose of this utility model is to provide a kind of environment-friendly type bilinearity cumulative explosive loading spacer that is not coupled, and realizes not coupling charging of large-diameter deep hole explosion cumulative.
The environment-friendly type bilinearity cumulative of the present utility model explosive loading spacer that is not coupled, it is characterized in that comprising that outer surface is arranged with the inner core of deep-slotted chip breaker, be enclosed within tube outer surface and the urceolus concentric with inner core in this, being filled with between described urceolus and inner core is mixed with the straw particle of binding agent, the top of described inner core is higher than urceolus, described in the bottom retraction of described inner core in urceolus.
The be not coupled feature of explosive loading spacer of environment-friendly type bilinearity cumulative of the present utility model is:
1. adopt concentric tubular nested structure, can guarantee that Yu Baokong axle center, powder column axle center is basically identical, can effectively reduce the uncertainty of traditional approach powder column placement location and the uncertainty of the hole wall that brings is destroyed;
2. inner core is arranged with arc energy concentrating groove, can form to monosymmetric jet cutting effect, improves explosive energy utilization rate and at the action effect of intending in seam direction;
3. urceolus diameter can change with blasthole diameter, and inner diameter of steel flue can be according to not coefficient of coup decision, and the chord length of arc energy concentrating cover and cover cone angle are determined according to explosive and blasting medium design, effectively improved demolition effect;
4. the utility model adopts segment design and use, divide intersegmental employing scalariform bayonet socket to coincide, can peg graft according to the degree of depth segmentation in big gun hole, form pre-charge pole, guarantee the continuity that spacer is axial along big gun hole and can prevent that junction powder charge from leaking outside, guarantee the Selection and Constitute of different hole depths, enhance productivity;
5. urceolus of the present utility model and inner core all use crops stalk crushing material, and material source is extensive, can be salvaged, and can not produce harmful chemical after blast, economical, pollution-free;
6. processing and fabricating is simple, on-the-spot easy to use.
The utility model is simple in structure, and demolition effect is good, easy to use, economic environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the environment-friendly type bilinearity cumulative of the present utility model explosive loading spacer that is not coupled, it is characterized in that comprising that outer surface is arranged with the inner core 4 of deep-slotted chip breaker 3, be enclosed within these inner core 4 outer surfaces and the urceolus 1 concentric with inner core 4, between described urceolus 1 and inner core 4, be filled with the straw particle 2 that is mixed with binding agent, this straw particle 2 plays the effect that connects inside and outside cylinder and buffering.Its symmetrically arranged deep-slotted chip breaker 3, can form to monosymmetric jet cutting effect, improves explosive energy utilization rate and at the action effect of intending in seam direction.The top of described inner core 4 is higher than urceolus 1, described in the bottom retraction of described inner core 4 in urceolus 1, form scalariform bayonet socket, can peg graft according to the degree of depth segmentation in big gun hole, form pre-charge pole, guarantee the continuity that spacer is axial along big gun hole and can prevent that junction powder charge from leaking outside, guaranteeing the Selection and Constitute of different hole depths, enhancing productivity.Its inside and outside cylinder all adopts crops stalk crushing material to make, and material source is extensive, can be salvaged, and can not produce harmful chemical after blast, economical, pollution-free.
The utility model is simple in structure, and demolition effect is good, easy to use, economic environmental protection.
