Description

The method and device that a kind of sillar is broken
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.
The technical solution of the present invention is: the method that this sillar is broken, and the method comprises the following steps:
(1) choose sillar more even curface as explosion face, and described explosion face is cleared up;
(2) surrounding in described explosion face installs Telescopic support;
(3) angle of each Telescopic support is regulated, it is ensured that each bracing frame is in vertical state, goes forward side by side Row angle locking;
(4) height of each Telescopic support is regulated, it is ensured that each bracing frame is positioned at sustained height, goes forward side by side Line height locks;
(5) Concentrated charge is positioned on the top platform of Telescopic support, and is fixed;
(6) detonating cord of the parts that detonate is connected rear haulage to appropriate location with Concentrated charge;
(7) place guard block in the periphery of sillar, prevent dispersing of blasting flyrock;
(8) detonate after checking safety Concentrated charge;
(9) the explosion face after being cut by Concentrated charge and explosion joint-cutting are cleared up;
(10) primacord is put in explosion joint-cutting in a designated order;
(11) detonating cord of the parts that detonate is connected rear haulage to appropriate location with primacord;
(12) around sillar, place guard block, prevent dispersing of blasting flyrock;
(13) detonate primacord, it is achieved the blast splitting of sillar.
Additionally provide the device of a kind of broken method of sillar, it include Telescopic support, Concentrated charge, Guard block, the parts that detonate, primacord,
Telescopic support, it is positioned on sillar, regulates its angle and makes each bracing frame be in vertical shape State, and carry out angle locking, regulate it and highly make each bracing frame be positioned at sustained height, go forward side by side Line height locks;
Concentrated charge, it is positioned at above Telescopic support;
Guard block, it is positioned at sillar periphery, prevents dispersing of blasting flyrock;
Detonate parts, and its detonating cord is connected with Concentrated charge, is also connected with primacord;
Primacord, it is positioned in joint-cutting after CUMULATIVE BLASTING.
The present invention make use of Tensile Strength of Rock be much smaller than the feature of comprcssive strength, utilize Concentrated charge to exist Sillar surface forms the joint-cutting of certain depth, and utilizes expansive force that primacord explosion produces by sillar from cutting Rive at seam;By adjusting the height that detonates of Concentrated charge, it is possible to achieve different depths of cut;Pass through Adjust the geometric shape of Concentrated charge, it is possible to achieve the difference of sillar ruptures lumpiness.Break with traditional machinery Broken method and drilled explosion crush method are compared, it is not necessary to the participation of heavy mechanical equipment, are more suitable for field work; Compared with simple energy-gathering jetting crush method, owing to using primacord to carry out secondary splitting, ratio can be crushed Bigger block stone.Therefore, it is possible to the sillar of the generous amount of quick crashing under mal-condition in the wild, and grasp Make simple.
