Description
Technical field
The present invention relates to a kind of building demolition set, specifically relates to a kind of building demolition set based on infrasound resonance technique.
Background technology
Wuhan Blasting Co. discloses a kind of building blasting demolition method, particularly a kind of composite structure building directed rolling type blasting demolishing method piecemeal.The method comprises the following steps: carry out pre-demolition to needing the building wall of demolition blasting; Bottom building, blasting cut is set; At blasting cut, place holes, and forms big gun hole; Powder charge in big gun hole; To the building of demolition blasting be needed to be divided into multiple region of detonating according to longitudinal axis, axis of pitch, described in region correspondence of detonating to detonate sequential; From back to front longitudinally, transversely from one end to the other end or two ends to centre, by time delay Nonel detonator outside region binding hole of detonating, form the blasting circuit by the region Directional Collapse that detonates of vertical, horizontal time delay.But the method run into baroque building or blasting scheme comparatively complicated situation time, engineering experience and empirical equation are just difficult to satisfy the demand.Explosive blasting sound is large simultaneously, and the shock wave that blast produces can bring disaster to surrounding environment or the people.Therefore need to create a kind of removal technology newly.
Resonance is the technical term that an operating frequency is physically very high, refers to that a physical system is under CF, does the situation vibrated with larger amplitude than other frequencies; These CFs are referred to as resonant frequency.Under resonant frequency, very little periodic vibration just can produce very large vibration, because system stores kinetic energy.When resistance is very little, resonant frequency approximately with system natural frequencies or claim intrinsic frequency equal, frequency when the latter is free oscillation.Resonator, its power is mainly that it can send the ripple of various frequency, and the ripple of these different frequencies acts on different objects, just can correspondingly produce a kind of resonance wave, when this resonance wave acquires a certain degree, object just can be made to be destroyed.In fact, resonance is lived closely related with us.The sound that sound source continues certain frequency sent can make glass broken.The operation of a machine can damage support because of resonance.A sound on high mountain is shouted, can cause the resonance of the accumulated snow on mountain top, causes a large snowslide in no time.The automobile travelled, if turnaround time just in time with the intrinsic cadence synchronization of spring, the resonance produced just can cause automobile out of hand, thus cause car crash ... since resonance has energy so, we can send infrasound by resonator and reach the effect that mankind's expectation is used for destroying discarded building.
Infrasound can be described as a double-edged sword to the mankind.On the one hand, infrasonic characteristic that people are produced by investigate natural phenomena and generation mechanism, more in depth can be familiar with characteristic and the rule of these phenomenons, and such as people utilize and measure aurora and produce infrasonic characteristic to study the rule etc. of aurora activity.The infrasound utilizing the tested sound source received to give off, detects its position, size and other characteristics, and the infrasound such as produced by receiving nuclear explosion, rocket launching cannon or typhoon removes to detect the relevant parameter of these sound source.Many disastrous phenomenons may give off infrasound as volcanic eruption, cyclone and thunderstorm etc. before generation, therefore likely utilize these premonitory phenomenons to predict Disaster Event etc.A kind of infrasonic wave generator comprises forcing air vibration to launch infrasonic electromagnetic vibration generator and the frequency control system in order to control vibration frequency.In conjunction with infrasonic wave generator and resonator, the demolition set for building of removing can be produced.
summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of building removal blasting method based on infrasound technology and resonance technique.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention is realized by following steps:
(1) on the building wall needing removal explosion, install the resonator for detecting building resonant frequency state;
(2) ground beyond building collapse safe distance is placed a Subsonic wave generator;
(3) Subsonic wave generator is opened, to the infrasound of building directional transmissions from 1Hz;
(4) resonator constantly detects and records out vibration frequency and the shockproofness of building;
(5) contrast sends shockproofness and the vibrating state of building after infrasound at every turn, selects maximum one group of data;
(6) start explosion to remove: to building the infrasound launching the highest shockproofness, building vibrations are more and more violent, realize explosion removal until collapse.
Adopt a kind of Subsonic wave generator, comprise amplitude-modulated wave signal generating circuit and ultrasonic oscillator, infrasound signal output apparatus exports infrasound signal to ultrasonic output circuit; Direct-current control voltage output circuit exports the input of voltage to frequency converter of 0-10V; Oscillator produces sinusoidal signal, obtains square-wave signal after the first voltage comparator shaping; Infrasound signal IP signal is converted to+15V and-15V square wave direct current voltage by the second voltage comparator; Gating circuit output frequency is the negative pulse signal INL of positive pulse signal INH and 40Hz of 40Hz; The high-frequency signal that power amplification circuit has exported by infrasound amplitude modulation is to ultrasonic oscillator ZL, because ultrasonic oscillator is embedded in underground, in soil, form the mechanical wave of amplitude infrasound change, the vibration in soil be exactly the superposition of two kinds of vibration waves and ultrasonic wave dither and slowly infrasound vibrate.By local to overall, from back to front longitudinally, transversely from one end to the other end or two ends to centre, the blasting circuit by the region Directional Collapse that detonates of formation vertical, horizontal time delay.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts infrasonic benefit: owing to being produced by ultrasonic wave, and forming range is little, easily shield, and operating efficiency is high.By infrasonic wave generator is set up in diverse location, can will need the building of demolition blasting by entirety to local, multiple region of detonating is divided into according to longitudinal axis, axis of pitch, the method accurately can control collapse direction, effective reduction blasting vibration and slump vibration, and the composite structure building of Collapse Length scope can be reduced.
