2), determine rock distribution and supporting course position in the hole according to the advance borehole data, need determining the degree of depth and the thickness of shot rock, and the quantity of definite blast hole and distribution;
3), be drilled with blast hole according to the quantity of blast hole, one of them blast hole can directly adopt advance borehole;
4), boring lays plastic catheter after finishing in advance borehole and blast hole, the plastic catheter degree of depth get final product at the bottom of being seated to the rock stratum of need explosion;
5), pass through rock distribution situation, the explosive consumption of calculating need explosion;
6), emulsion is seated in the plastic tube, and detonating capsule is linked to each other with explosive with blastic fuse, carry out the aperture protection;
7), utilize Millisecond Controlled Blasting, with the fragmentation of hole domestic demand shot rock.
In order to realize aforesaid method, the utility model has adopted such device, this device comprises bored concrete pile, wherein in bored concrete pile, be provided with for the degree of depth and the advance borehole of thickness and the blast hole that is used for the filling explosive that need to determine shot rock, in advance borehole and blast hole, be provided with plastic catheter, plastic catheter is being positioned at and need laying emulsion in the shot rock position, and this emulsion links to each other with blastic fuse with detonating capsule.
Further, be provided with protector in the aperture of advance borehole and blast hole, this protector can be the conventional equipments such as protective cover, protective cover, protection network, to guarantee construction safety.
Further, the quantity of blast hole is 3～10, and is evenly arranged in Punching Borehole Cast-in-place Concrete Pile, to guarantee demolition effect and hole quality.Be drilled with first advance borehole, be drilled with again blast hole, and with advance borehole as one of blast hole, the big gun hole site of conduct enforcement explosion, size are by advance borehole like this, can guarantee the accuracy of basement boulder layer depth and thickness distribution, can with advance borehole as blast hole, reduce the boring workload again.
Further, the bottom degree of depth of advance borehole is positioned at below the supporting course of rock stratum, satisfies load requirement with the degree of depth that guarantees bored concrete pile, and blast hole only needs to guarantee that plastic catheter can arrive needs the shot rock bottom get final product, with the minimizing workload of holing.
Further, the emulsion that is used for the rock of explosion different depth is connected in series in plastic catheter.
Owing to adopted the technical solution of the utility model, the utility model is in carrying out bored concrete pile during multilayer rock original position construction of blasting pore-forming, the quantity of blast hole and explosion medication are determined according to the rock distribution degree of depth and thickness, dosage is according to calculating, the connection between theory and practice can obtain preferably demolition effect; Multilayer boulder, lithosphere detonate simultaneously, avoid secondary to draw hole and explosion, save circulating time; Blast hole is by advance borehole, and the installation plastic bushing, and both having guaranteed needs the degree of depth of shot rock and the accuracy of thickness distribution, can guarantee again the fairness in the rendrock installation course, security and the better performances of detonating; The multilayer boulder adopts plastic detonating tube nonel ignition system to form the inside and outside time elementary errors in hole, detonates the time enough interval is arranged in every group of big gun hole or each big gun hole, and blasting vibration is by independent cartridge bag effect, boulder under the bad land, accelerate punching stake progress, save the duration, create duration benefit and economic benefit.
