Description
Technical field
The utility model belongs to engineering explosion clothing arts, and in particular to a kind of blasthole that can be used in rock blasting construction
Block spacer.
Background technique
Engineering explosion technology is often used in the fields such as water conservancy and hydropower, mine, traffic.Traditional continuous cylindrical charge
That there are unit consumption is big, detonation pressure is excessively high, the overground disadvantage of rock powder, so that the effective utility of laser power of explosive is low, and is easy
Bring the problems such as larger blasting vibration.
Chinese patent CN01212086.3 discloses a kind of deep hole balst spacer, is by two partitions and to be located at this two partition
Between pillar constitute, though structure is simple, partition is the rigid solid of timber or plastic production, into cannot be in blast hole
Explosion hole shape tightly coincide, and the leakproofness of size hour, upper and lower baffle space are poor, influences demolition effect.When size is big, with hole
Wall is easy clamping stagnation, causes that setting position can not be reached.
Chinese patent ZL02276267.1 discloses a kind of blasthole gas spacer, it is by airbag flexible and airbag
In air charging system constitute this kind of spacer, using the compressed gas filling airbag of the gas cylinder in release airbag, or utilize gas
The gas filling airbag that body generator generates, airbag and explosion hole wall after making inflation are in close contact, and are formed bearing capacity, are realized quick-fried
The interval filling of explosive in holes, but there is security risks in transport carries for the compressed gas of this spacer, and tie
Structure is cumbersome, troublesome in poeration, and working efficiency is low, and the size of isolation is also inaccurate, to influence the quality and effect of explosion.
Chinese patent ZL200620161101.8 discloses a kind of gas spacer, this spacer does not need high-pressure gas,
But directly inflated using compressor, but on condition that must be equipped with a kind of dedicated charger when in use, higher cost, together
When operating cost when complicated, low efficiency.And cracky when the airbag of above two spacer has encountering sharp object.
Therefore a kind of quick and easy, cheap multiple-row blasting spacer urgently proposes.

Detailed description of the invention
Fig. 1 is the structural schematic diagram of multiple-row blasting spacer involved in the utility model embodiment；
In figure, 10- multiple-row blasting spacer, 11- cylinder cloth bag, 12- self-locking band, 13- cross bar, 14- lifting rope, 15-
Blocking filler, Z- explosive, the airspace K- section.
Specific embodiment
Multiple-row blasting spacer involved in the utility model is elaborated referring to the drawings.
<embodiment>
Certain hydraulic and hydroelectric engineering foundation excavation uses spaced loading, wherein blocking section design length is 0.2m, blasthole aperture
For 50mm, to accelerate interval multiple-row blasting, reducing engineering cost, multiple-row blasting use the utility model proposes multiple-row blasting between
Interval multiple-row blasting is carried out every device.
As shown in Figure 1, multiple-row blasting spacer 10 includes cylinder cloth bag 11, self-locking band 12, cross bar 13 and lifting rope
14。
Cylinder cloth bag 11 is cylindric bag body open at one end, its length is opposite with the design length of multiple-row blasting section
It answers, outer diameter is corresponding with the aperture of blasthole, and inside is for loading blocking filler 15.In the present embodiment, cylinder cloth bag 11 can
Canvas, nylon etc. is selected to have the cloth of certain wearability；The length of cylinder cloth bag 11 is equal with the design length of multiple-row blasting section, is
0.2m；The outer diameter of cylinder cloth bag 11 is 0.95 times of blasthole aperture, i.e. 48mm；Blocking filler 15 is landwaste or sand.It is logical
Such design is crossed, cylinder cloth bag 11 is facilitated fast, safely to fall, guarantees that cylinder cloth bag 11 can fill up entirely radially
Blasthole.
Self-locking band 12 is used for after cylinder cloth bag 11 has loaded blocking filler 15, quickly, binds envelope securely
Close the sack of cylinder cloth bag 11.In the present embodiment, using nylon cable tie as self-locking band 12.
The length of cross bar 13 is bigger than the aperture diameter of blasthole, is laterally erected on the aperture of blasthole, stifled for bearing to fill
The weight of the cylinder cloth bag 11 of plug filler 15.In the present embodiment, using can be using the waddy of load-bearing 10kg as cross bar 13, it
Length be 1.5 times of blasthole aperture, it is ensured that do not fall off when whereabouts to blasthole, and be able to bear cylinder cloth bag 11
Bring lower pulling force.
One end of lifting rope 14 is tied up to by 11 sack of cylinder cloth bag after binding closing, and the other end ties up on cross bar 13, hangs
Rope 14 makes to fill 11 sack of cylinder cloth bag of plug filler 15 downward, hangs and be filled in the predetermined position of multiple-row blasting section
To form blocking section.In the present embodiment, lifting rope 14 using can load-bearing 8kg wear-resisting rope, length be 26cm (guarantee both ends fasten
Afterwards, cylinder cloth bag 11 can fall and be located at the predetermined position of blocking section)；Tether mode is sailor's knot or fast knot etc.；To make
The lower backwardness of cylinder cloth bag 11 can fit closely with hole wall, and to ensure blocking effect, it is empty that lifting rope 14 should occupy lesser blasthole
Between, it should not be excessively thick, 14 diameter of lifting rope is 7mm in the present embodiment.
Based on the above structure, the concrete operation method of multiple-row blasting spacer 10 provided by the present embodiment are as follows: by cross bar
13 hang on aperture, and downward by 11 sack of cylinder cloth bag for filling plug filler 15, keep cylinder cloth bag 11 slow by self weight
It falls under slow automatic from the 20cm of aperture at, lifting rope 14 stretches completely at this time, and the cylinder cloth bag 11 for filling plug filler 15 is formed
Section is blocked, and forms airspace section K between blocking section and explosive Z, so far entirely interval multiple-row blasting is completed.
In the actual operation process, since the gravity for loading object in cylinder cloth bag 11 can make cylinder cloth bag 11 be sunk,
Therefore 11 top of cylinder cloth bag will form one section of vacancy 2~4cm with that will not flush completely between aperture, and cylinder cloth bag
11 bottom actual depths are at 22cm~24cm, but the phenomenon does not influence multiple-row blasting and demolition effect.
Above embodiments are only the illustration done to technical solutions of the utility model.Involved in the utility model
Multiple-row blasting spacer is not merely defined in described structure in the embodiment above, but defined by claim
Subject to range.Any modify or supplement or wait that the utility model one of ordinary skill in the art are done on the basis of the embodiment
Effect replacement, all in the utility model range claimed.
