Abstract
An energy-concentrated tube provided with cutting slots is made of high pressure polyethylene plastics, wherein, two symmetrical cutting slots are formed on the energy-concentrated tube in the longitudinal direction of the energy-concentrated tube; and a third cutting slot is formed at the middle part of the top part on one side of the two cutting slots, and a groove for controlling the directionof the cutting slot is formed at the bottom part. The energy-concentrated tube provided with the cutting slots is characterized in that the blasting cracks of wall rocks can be reduced, the integrityand the stability of the wall rocks are retained, the periphery outline of a laneway is led to be more smooth, favorable conditions can be created for the operation of a spray pipe, the number of periphery holes is reduced, the drilling time is shortened, and the energy-concentrated tube is an ideal explosion device for colliery laneway gold digging at present.
Description
Affiliated technical field
The utility model belongs to a kind of demolition set that is used for the coal mine roadway driving.
Background technology
Existing coal mine roadway driving technology, bigger to surrounding rock failure after explosion, the big gun crack of shattering is more, the roadway forming out-of-flatness, scar to surpass, owe the amount of digging bigger.
Summary of the invention
In order to overcome the problem that exists in the above-mentioned existing coal mine roadway tunneling process, the purpose of this utility model is that a kind of binding energy tube that has joint-cutting will be provided, this binding energy tube not only can make rock be split along tunnel design profile line, reach and be shaped smoothly, and can reach and reduce the shatter purpose in crack of country rock big gun.
The technical scheme that its technical problem that solves the utility model adopts is: the external diameter of binding energy tube is φ 29, and internal diameter is φ 27, and length is divided into three kinds of specifications such as 200mm, 250mm and 300mm.Along binding energy tube vertically be provided with two joint-cuttings with the axis symmetry, every joint-cutting is divided into 2 sections, 3 sections, wide 2mm is provided with the wide lacing wire of 5mm in the middle of long 89mm * 2,76mm * 3,90mm * 3, the two section adjacent joint-cutting.On this basis, be provided with the 3rd joint-cutting in the centre at the top of two symmetrical joint-cutting one sides, be divided into 2 sections, width is 2mm, and length is to leave the wide lacing wire of 5mm in the middle of section adjacent joint-cutting of 72mm * 2, two.The groove that connects overall diameter is made in the bottom of binding energy tube so that when the filling explosive, the flat end of tamper is embedded wherein, control that it cracks towards.In blasting process, make binding energy tube itself produce inhibition and the guide effect of moment to detonation, and provide the transient state discharge space by joint-cutting, make detonation pressure form high fluence at the joint-cutting place, concentrate on the outline line direction of tunnel and conduct, make it produce crack and directed expansion along the outline line orientation preferentially.
The beneficial effects of the utility model are: reduced the big gun crack of shattering, kept the integrality and the stability of country rock, made the profile of tunnel-surrounding more smooth.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is a schematic diagram of the present utility model.
Among the figure 1. the binding energy tube body, 2., two symmetrical joint-cuttings, 3., the 3rd joint-cutting, 4, groove, lacing wire.
The specific embodiment
Polyethylene after crushed, add antistatic and antifreezing agent, put into the hopper of blow moulding machine, dissolve the joint-cutting that contains two symmetries 2 that blowing goes out certain specification and the reset condition plastic barrel of the 3rd joint-cutting 3 through heating, lacing wire 5 forms in the blowing process, and plastic barrel is through natural cooling, Gu after the shape, by manually the bossing of joint-cutting being peeled off with blade, the certain position on plastic barrel top cuts, and promptly forms binding energy tube body 1.Groove 4 forms in the blowing process.
Claims (2)
1, a kind of binding energy tube that has joint-cutting, the external diameter that it is characterized in that binding energy tube body (1) is ф 29, internal diameter is ф 27, and the bottom is provided with a groove (4), longitudinally is provided with two symmetrical joint-cuttings (2), wide 2mm, long 89mm * 2,76mm * 3,90mm * 3, article two, symmetrical joint-cutting (2) is divided into 2 sections, 3 sections, and long is 72mm * 2.
2, a kind of binding energy tube that has joint-cutting as claimed in claim 1, it is characterized in that two to journey joint-cutting (2) with binding energy tube axis symmetry, be provided with the 3rd joint-cutting (3) in the centre at the top of a side of two symmetrical joint-cuttings (2), length is 72mm * 2.
