Description
Technical field
The present invention relates to a kind of method that sillar is broken, and the device of use the method, be mainly used in big
Block sillar crushes.
Background technology
Severe earthquake action often induces the disaster such as avalanche, landslide, causes the sillar of generous amount to tumble and block
Road, hinders the entrance of speedily carry out rescue work vehicle and goods and materials, and therefore needing adopts an effective measure carries out the most broken of sillar
Broken and remove.
At present, carry out the broken method predominantly organic tool crush method of bulk sillar and blast crush method this two
Kind.
Equipment involved by mechanical crushing method includes lithotrite, splitter etc..Stone breaking machine mainly utilizes machinery
Can carry out the broken of bulk sillar, its core component is the lithotrite similar with shallow bore hole impacter.Splitter
Utilizing wedge principle to be cleaved from default seam by sillar, it is made up of pumping plant and splitter two parts.
Blast crush method includes bore blowing-up method, energy-gathering jetting method and boring this three class of fluid jet.Hole quick-fried
Broken method is typically holed in sillar center when implementing, and puts into a certain amount of explosive in hole, and in boring
Top necessarily blocks, and utilizes the expansion energy of blast impulse energy and detonation gas to carry out brokenly rock after detonating.
Flexible linear-shaped charge is placed at the above certain distance in sillar surface, by quick-fried after explosive initiation when energy-gathering jetting method is implemented
The expansion energy of angry body is rapidly converted into the kinetic energy of cavity liner, utilizes the gold formed in cavity liner motor process
Belong to jet and carry out brokenly rock.The construction technology of boring fluid jet is basically identical with bore blowing-up method, simply with poly-
Tradition medicated bag can be instead of by medicated bag, carry out combined-breaking rock by the expansion energy of energy-gathering jetting and detonation gas.
Mechanical crushing method operating process is simple, but broken rock equipment is bigger, it is impossible to rapidly enter disaster area specific bit
Put enforcement crushing operation；There is difficulties involved when additionally, this kind equipment ruptures the diameter sillar more than 2m.
Bore blowing-up method and boring fluid jet are required to punch on sillar surface, due to the restriction of environmental condition, electricity
Bore and air drill is the most inapplicable.Needed for energy-gathering jetting method, equipment is the lightest, easy to carry, but the method shape
The jet crack become is shallower, it is impossible to realize effectively rupturing of generous amount sillar.
Summary of the invention
The technology of the present invention solves problem: overcome the deficiencies in the prior art, it is provided that a kind of sillar crushes
Method, its can the sillar of the generous amount of quick crashing under mal-condition in the wild, and simple to operate.
