Abstract
The invention discloses a water pressure composite quick blocking method applied in drilling and blasting. The quick blocking comprises a water bag, a dynamite roll, a water bag and a high-molecular resin sealing bag. the water bag of the first segment is placed at the bottom of a hole opening; the dynamite roll of the second segment is closely connected with the water bag in series; the water bag of the third segment is placed behind the dynamite roll of the second segment; the high-molecular resin material of the fourth segment is placed in a drilling after kneading, squeezing and foaming; the high-molecular resin material flows out as liquid and penetrates into the space among the dynamite, the water bags and socks; quick solidification is performed and blast holes are blocked. the viscosity of the high-molecular resin material with rocks is larger than that of traditional stemming. the impact wave produced by the explosion of the dynamite is directly applied on rocks through the water bag installed at the bottom of the blast hole and therefore the explosive energy consumption is reduced and blast hole utilization is increased. The water bags in the blast hole generates water atomization effect during explosion which can reduce air impact wave, absorb explosive dust and dilute poisonous gases.
Description
Technical field:
The invention belongs to Geotechnical Engineering field, be specifically related to a kind of hydraulic pressure for drillhole blasting and be combined rapid blocking method.
Background technology:
In engineering explosion, multiple-row blasting is an important step of engineering construction, is also to affect project progress and construction quality
One of them key factor.Due to the volume of smoke produced after explosion, pollute environment, have become as restriction blasting excavation and carry
High bottleneck.Although at present hydrous taphole loam (or hydraulic pressure) choked technique the most reduces flue dust, but use water bag and traditional
Yellow mud is as plugging material, and due to operation complexity, elapsed time is long, and stemming is met water and can be softened, the most high with rock caking ability former
Cause so that multiple-row blasting effect is difficult to be guaranteed, explosive energy utilization rate is the most on the low side, and cyclic advance is relatively short.Therefore,
This invention is exactly to produce in this context.
Summary of the invention:
It is an object of the invention to provide a kind of shortcoming overcoming above-mentioned traditional method, duration of congestion can be shortened, increase explosive energy
Amount utilization rate, improves digging footage, can reduce again dust and gun smoke concentration purpose one blasthole blocking up method.
The hydraulic pressure being applicable to drillhole blasting is combined rapid blocking method, comprises the following steps:
Step 1, puts into water bag bottom big gun hole；
Step 2, puts into big gun hole continuously by explosive cartridge, and closely coupled with bottom water bag；
Step 3, loads big gun hole by water bag, and closely coupled with explosive；
Step 4, will be equipped with the sack of the black material of macromolecule resin premixed systems and white material and carries out rubbing crowded, and liquid crushes middle unbonded jail
The impression leaned on, makes macromolecule resin premixed systems fully merge foaming；
Step 5, treats slightly to heave equipped with the sack of macromolecule resin premixed systems liquid, tears opening by bag tears mouth, dress
Enter big gun hole, and closely coupled with water bag, and macromolecule resin material foaming can be flowed out from sack stress weakness and filled up big gun hole and formed
Solid, binds with rock, i.e. completes blocking.
The vinyon that above-mentioned water bag is general is made, for cylindrical shape.
Bottom above-mentioned steps 1, water bag stemming length is the 5%～10% of big gun hole total length.
Above-mentioned steps 3 water bag stemming length is the 10%～40% of big gun hole total length.
The above-mentioned sack equipped with macromolecule resin premixed systems be aluminium foil, general vinyon etc. can heat bonding material, sack
There is impression centre, but unbonded firm.
The above-mentioned black material equipped with macromolecule resin premixed systems and white material are liquid, are attached separately to the both sides of sack middle impression.
The black material of above-mentioned macromolecule resin is configured to be divided into polyisocyanates.
The white material of above-mentioned macromolecule resin is configured to be divided into Sucrose polyethers polyhydric alcohol 45%～50%, foaming agent 14%～16%, urges
Agent 0.2%～1%, foam stabiliser 2%～3%, fire retardant 14%～20%, cross-linking agent 10%～14%.
The mass ratio of the black material of above-mentioned macromolecule resin and white material is 1: 1.
Compared with the prior art the present invention, fully shows following advantage in practice:
1, the Explosive stress wave effect that explosive charge produces is placed on the water bag bottom big gun hole and hole wall rock, reduces punching explosive energy
The consumption of amount, improves blast hole utilization factor.
2, the water bag being placed in big gun hole can produce water wedge and atomizing at explosion time, plays and weakens air-shock wave and trapping explosion
Produce the effect of dust, absorb toxic gas.
3, hydraulic pressure compound blocking big gun hole, one is to reduce traditional stemming blocking time, convenient and swift；Two is macromolecule resin material
Flowing out with liquid condition, penetrate in the gap between explosive, water bag and rock, solidification intensity is compared with the blocking of traditional stemming
Higher, increase explosion energy utilization rate, reduce the punching in big gun hole, improve blasting efficiency.
Accompanying drawing illustrates:
Fig. 1 is inventive method schematic diagram；
Fig. 2 is macromolecule resin packaging bag schematic diagram.
In figure: water bag bottom 1-hole, 2-explosive cartridge, 3-water bag, 4-macromolecule resin, 5-detonator, 6-impression,
7-tearing port, the black material of 8-, 9-expects in vain.
Detailed description of the invention:
It is embodied as introducing technical scheme below in conjunction with certain vcehicular tunnel explosion:
Certain vcehicular tunnel explosion: hole deep 3.8m, aperture 38mm, uses continuous charging.
For above-mentioned big gun hole, the detailed description of the invention of the inventive method is as follows:
(1) water-saving bag 1 is loaded bottom big gun hole.Originally the used water bag long 200mm of each joint it is embodied as, a diameter of
35mm, bag thickness is 0.8mm, the cylindrical shape made for general vinyon.
(2) explosive 2 is loaded big gun hole, closely coupled with water bag 1, and detonator 5 is pulled out aperture.Originally institute it is embodied as
The explosive used is emulsion, and powder charge total length is 2.8m.
(3) four water-saving bags 3 are loaded big gun hole, closely coupled with explosive 2.
(4) sack that will be equipped with the black material of macromolecule resin 8 and white material 9 is rubbed crowded, squeezes middle impression 6, black material 8 and white material 9
