Abstract
The utility model discloses an environment-friendly circumferential explosive loading spacer which realizes circumferential uniform uncoupled explosive loading. With a concentrically nested structure, the environment-friendly circumferential explosive loading spacer comprises an inner barrel, an outer barrel, a seal pad, and connecting rib plates. The inner barrel is disposed in the outer barrel; the inner barrel and the outer barrel are disposed in a staggered manner, with the upper end of the inner barrel higher than the upper end of the outer barrel and the bottom end of the inner barrel higher than the lower end of the outer barrel; an air annulus between the upper end of the inner barrel and the upper opening of the outer barrel is sealed and covered by the seal pad; and the connecting rib plates are connected between the inner barrel and the outer barrel. The spacer realizes circumferential uniform air space explosive loading in a blast hole; with segmented design and use, the spacer guarantees selective assemblies of different hole depths; terraced bayonets are employed for fit between sections, and a ladder-shaped connecting structure guarantees continuity of the spacer along the axial direction of the blast hole and prevents outward leakage of explosive from joints; the spacer can be made of diverse materials and is economical and causes no pollution; and the spacer is easy to process and manufacture and is easy to use on site.
Description
Technical field
The utility model relates to mining and Geotechnical Engineering equipment, especially a kind of environment-friendly type hoop explosive loading spacer.
Background technology
The production explosion that leaning in ground explosion in the explosion of limit in large-scale hydroelectric project slope excavating group, the urban construction or excavation of foundation pit explosion, the large surface mine exploitation helped explosion and some non-metal mine etc. all has some common requirements; That is: alleviate the explosive opposite side and help the integrity that the slope is bad, edge protection is helped, and then reduce the maintenance cost of side slope; Reduce the explosion earthquake intensity of wave, alleviate the flutter failure of explosion, alleviate the excessive pulverizing on every side of big gun hole side slope or surrounding buildings thing.For realizing these requirements, what often adopt in the engineering is coupling charging technology, and coupling charging is not divided into and axially is not coupled and hoop is not coupled, and axially coupling charging is not realized through using axial powder charge spacer, and in explosion, is applied.And at present hoop is not coupled and realizes through reducing cartridge size; But the hoop position of powder column in the big gun hole is uncertain; Easily near big gun hole inwall one side and opposite side has bigger airspace; Though this free style structure meets the demands when calculating not the coefficient of coup, it is serious to cause a side opening wall to destroy in the blasting practice easily, can not realize the effective protection of limit group and the even reduction of seismic wave.Thereby provide a kind of hoop explosive loading spacer to have industrial prospect clearly.
The utility model content
The utility model provides a kind of environment-friendly type hoop explosive loading spacer, realizes evenly coupling charging not of hoop,
The environment-friendly type hoop explosive loading spacer that the utility model provides is characterized in that this spacer is the nested, concentric formula, and its structure comprises: inner core, urceolus, packing, connection gusset; Inner core places in the urceolus; Inner core, urceolus are crisscross arranged, and the inner core upper end is higher than urceolus, and the lower end is shorter than urceolus; The packing capping use with the air ring at urceolus place suitable for reading in inner core upper end, uses between inner core and the urceolus to be connected the gusset connection.
Described connection gusset is symmetrical set, and quantity is 6 ~ 8.
The environment-friendly type hoop explosive loading spacer that the utility model provides compared with prior art, its useful effect is embodied in:
1. environment-friendly type hoop explosive loading spacer adopts concentric tubular nested structure; Can realize hoop even airspace powder charge in the big gun hole; And can realize the not adjustment of the coefficient of coup according to designing requirement; Both guaranteed locus stable between inner/outer tube, and can make spacer in the water hole, be easy to sink at the bottom of the hole again.
2. spacer adopts segment design and use, guarantees the selection combination of different hole depths, divides intersegmental employing scalariform bayonet socket to coincide, and trapezoidal syndeton guarantees the continuity that spacer is axial along the big gun hole and can prevent that the junction powder charge from leaking outside.
3. it is extensive to make the material source that spacer uses, can twice laid, and choose environment-friendly materials and process spacer, after blast, can not produce harmful chemical, economical, pollution-free.
4. processing and fabricating is simple, and is on-the-spot easy to use.
Description of drawings
Fig. 1 is an environment-friendly type hoop explosive loading spacer longitudinal profile sketch map;
Fig. 2 is an environment-friendly type hoop explosive loading spacer horizontal section sketch map.
The specific embodiment
Like Fig. 1, shown in Figure 2, environment-friendly type hoop explosive loading spacer is the nested, concentric formula, and its structure comprises: inner core 1, urceolus 2, packing 3, connection gusset 4; Inner core 1 places in the urceolus 2; Inner core, urceolus are crisscross arranged, and the inner core upper end is higher than urceolus, and the lower end is shorter than urceolus; The air ring at inner core 1 upper end and urceolus 2 places suitable for reading is with packing 3 cappings, uses between inner core 1 and the urceolus 2 to be connected gusset 4 connections.Connect gusset and be symmetrical set, quantity is 6 ~ 8.The material of making spacer uses straw, and not only economy but also environmental protection have been avoided secondary pollution.
Claims (2)
1. an environment-friendly type hoop explosive loading spacer is characterized in that this spacer is the nested, concentric formula, and its structure comprises: inner core, urceolus, packing, connection gusset; Inner core places in the urceolus; Inner core, urceolus are crisscross arranged, and the inner core upper end is higher than urceolus, and the lower end is shorter than urceolus; The packing capping use with the air ring at urceolus place suitable for reading in inner core upper end, uses between inner core and the urceolus to be connected the gusset connection.
2. environment-friendly type hoop explosive loading spacer according to claim 1 is characterized in that said connection gusset is symmetrical set, and quantity is 6 ~ 8.
