Abstract
A kind of demolition blasting blast hole stemming tamper.Structure type is made up of two parts, and Part I is club head, cylinder, and total length sets a U-shaped slot to make way to club head outer wall vertically；Part II is rod body, and rod body diameter is less than club head diameter.The tamper can effectively protect detonator wire without damage in demolition blasting blast hole stemming, make filling is closely knit not stay dead angle so as to ensure quality, and can improve filling efficiency, and operation is time saving and energy saving.
Description
Technical field
The utility model belongs to engineering explosion field, the blast hole stemming for demolition blasting, it can also be used to which other are suitable
Shallow blasting blast hole stemming.
Background technology
At present, the blasthole of demolition blasting is required to be clogged using special stemming in engineering explosion, the quality of filling
The control of the explosions such as quality and slungshot, the shock wave of demolition effect harm is directly affected, it is usually to pass to clog the instrument used
The cylindrical wooden tamper of system, this tamper material source is wide, easy to process, easy to use, cheap, but the shortcomings that exist
It is that there is the extruding of larger tamper, impact detonator wire during filling（The insulated conductor or on-electric detonator of electric cap
Plastic detonating tube）The risk being damaged to, during operation it is important to note that and because itself and blasthole are cylinder, cause
Make detonator wire two side areas filling compactness relatively low, overall filling quality is uneven；Chinese patent CN200720152429.8
The thinking that the groove of setting one of proposition is used to place detonator wire is fine, but is not meet demolition blasting to fill out along elongated set of tamper
The actual conditions of plug, detonator wire is more naturally to stretch out to be attached on blasthole wall in blasthole, rather than preferable straight line
When stretching, therefore smashing pressure stemming using the tamper, detonator wire can rub repeatedly with trench wall, and tamper is smashing pressure stemming repeatedly
When detonator wire easily with groove depart from, so as to cause tamper extruding cutting damage detonator wire probability it is bigger；Chinese patent
It is a much progress that the tamper that CN201521009483.8 is proposed, which can adjust length, but except Chinese patent can not be overcome
Beyond the shortcomings that CN200720152429.8, its sleeve structure and stretching structure to become in using and processing it is relative complex and
Inconvenience, cost can also increase.
The content of the invention
In order to overcome the fragile detonator wire of existing tamper and filling quality in the construction of demolition blasting blast hole stemming uneven
Even deficiency, the utility model provide a kind of tamper, and the tamper is not only simple in structure, is cheap, be easy to operate, and can have
Effect protects detonator wire, filling are closely knit not stay dead angle, ensures filling quality, is the ten of a kind of shallow blastings such as demolition blasting filling
Divide effective instrument.
Technical scheme is used by the utility model solves its technical problem：Structure type is made up of two parts, and first
Part is club head, cylinder, shorter, and main function is compacting stemming, and total length sets a U-shaped to step down to club head outer wall vertically
Groove, function are to reserve space for the detonator wire in blasthole, club head is not rushed when fully smashing stemming around pressure detonator wire
Hit, extrude detonator wire.Club head is unsuitable long, long, becomes the contact area of slot to make way and detonator wire and is rubbed so as to increase greatly
The probability of resistance increase damage detonator wire is wiped, while also increases club head and the contact area increase frictional resistance of blasthole perisporium,
So as to increase operation difficulty.Club head external diameter is slightly larger than traditional tamper diameter, can so increase and smash pressure surface product raising filling effect
Rate；Part II is rod body, cylinder, and main function is that support club head is completed to smash pressure stemming, and rod body diameter is less than club head diameter,
Rod body diameter should be less than club head diameter with slot to make way diameter sum, and so when club head smashes pressure stemming, can greatly reduces rod
The contact friction probability of body and detonator wire and blasthole perisporium, had both been beneficial to protection detonator wire, it is again laborsaving to smash pressure stemming.
The beneficial effects of the utility model are both to have remained the advantages that traditional tamper is simple in construction, cheap, and can is enough
Effectively protection detonator wire is without damage in blast hole stemming, makes filling is closely knit not stay dead angle so as to ensure quality, and can
Filling efficiency is improved, operation is time saving and energy saving.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
1. club head in figure, 2. slots to make way, 3. rod bodies.
Embodiment
In Fig. 1, club head（1）Diameter 38mm, high 30mm；Slot to make way（2）Wide 3.5mm, depth 3.5mm；Rod body（3）Diameter
24mm, length can be according to filling situation customizations.The size in each portion of the utility model can be according to actual blasthole diameter, detonator number
Amount, filling height are suitably adjusted, optional timber of material etc..
Demolition blasting blast hole stemming method, after the completion of powder charge in blasthole, first by the good section stemming egg dress of pre-production
Enter blasthole, then make club head（1）On slot to make way（2）Detonator wire is directed at, holds rod body（3）Gently stemming egg is made a gift to someone hole
It is interior, pressure is gently smash repeatedly, then the second section stemming egg is put into blasthole, repeats said process, and each section stemming egg smashes pressure
Dynamics gradually increases, until blast hole stemming is closely knit to reach requirement.Tamper should move along the direction of detonator wire during smashing pressure,
That is detonator wire and slot to make way（2）All the time it is parallel, avoid strength when the two is at an angle of and promote crowded bad detonator wire, rod body（3）As far as possible
Parallel with blasthole, frequently contact increases frictional resistance so as to increase filling difficulty when avoiding smashing pressure filling.
Claims (1)
1. a kind of demolition blasting blast hole stemming tamper, is made up of club head and rod body, it is characterized in that：Club head outer wall total length vertically
One U-shaped slot to make way is set.
