Description
Technical field
The utility model relates to beehive-shaped charge blasting technique field, specifically refers to the adjustable layout of linear shaped charge device of a kind of combined type.
Background technology
For the Slope Controlled Blasting of the roadbed, tunnel, vertical shaft, hole stake, channel etc. of the engineering such as traffic, water conservancy, the blasting technique that tradition adopts is presplitting (light face) explosion, its technical characterstic is in the intensive boring in side slope place, Uncoincided charge in hole, then 7 mouthfuls, big gun hole is blocked, quick-fried together, utilize explosive blasting generation stress to involve blasting fume stress and make adjacent shot hole medium (as rock) drawing crack, gases at high pressure contract enters splitting, forms smooth side slope face.This kind of mode charge process is coarse, generally with bamboo chip by the colligation of explosive interval, fuse arming test experiment initiation technique is thick, meanwhile, also has following shortcoming: 1, Half cast factor is generally at 30%-90%, and Slope leveling degree is not high, fluctuates in positive and negative 150mm; 2, pitch-row is generally 8 ~ 12 times of big gun footpath, and boring amount is large, and efficiency is low; 3, owing to adopting the mode of intensive boring, its explosive consumption is large, and engineering cost is high; 4, due to presplit blasting, once neat quick-fried dose is large, and vibrations are large, make the presplit blasting being originally used to shock dropping, and presplit blasting vibration on the contrary impact is large.
In order to solve the problem, occur utilizing existing presplitting (light face) layout of linear shaped charge blasting principle to carry out bipolar linear cavity energy demolition set, it comprises bipolar layout of linear shaped charge tube seat and cavity liner, in this device, bipolar layout of linear shaped charge tube seat is formed in one structure, it is cumulative in plane of symmetry vertical direction, formed at a high speed, high pressure, high density knife-edge detonation product, utilize linear cavity liner that the potential energy of cumulative air-flow is become kinetic energy, can increase seldom in this concentration of energy process, energy is converted primarily into kinetic energy form, form one speed and the kinetic energy metal flow higher than gas flow, speed reaches 7000 ~ 8000 meter per seconds, high-speed jet like this is got on target plate, momentum becomes hundreds thousand of and even 1,000,000 atmospheric pressures, the intensity of target plate material plate or rock seems insignificant.Its blasting technique adopted relative to tradition has advantage as follows: pitch-row is 18 ~ 30 times of big gun footpath, boring amount reduces, and efficiency is high, and Slope leveling degree is relatively high, because boring amount is few, effectively reduce the consumption of explosive, energy-conserving and environment-protective, effectively reduce cost, cost reduces more than 50%, and explosion damages little to reservation side slope, blasting vibration is little, suitable for city explosion.But also there is following deficiency in it: 1, because bipolar layout of linear shaped charge tube seat is integrated overall structure, the angle of its beehive-shaped charge cavity liner is non-adjustable, the cavity liner of different angles and material cannot be changed, very inconvenient for trying quick-fried test parameter early stage; 2, bipolar linear cavity energy cartridge bag, especially blast hole has been reserved at center, hole, needs Special Equipment to carry out charging operation, and on-the-spot processing can not ensure that the position of primacord in hole is accurate, affects demolition effect; 3, existing bipolar layout of linear shaped charge, cumulative direction is straight line, 180 degree, two cumulative angular separation exactly, be used on straight line outline line effective, but due to bipolar linear cavity energy cartridge bag cumulative orientation angle non-adjustable, adjustment direction needs again to make tube seat mould, causes tube seat not general, not only cost is high, and complicated operation; When 4, carrying out presplitting (light face) explosion on tunnel vault curve or inverted arch curve, two-stage cumulative direction is still 180 degree, now after curve slope blasting at the holes cumulative blasting line joint place straight line amount of backbreaking X1=R(1/cos α/2-1), the amount of backbreaking is large, and side slope surface irregularity, side slope curve are not round and smooth.
