Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] The present invention is realized through the following embodiments:

[0022] Step 1. Install a resonator on the wall of the building that needs to be demolished and blasted to detect the resonance frequency state of the building;

[0023] Step 2. Place a sound wave generating device on the ground beyond the safe distance of building collapse;

[0024] Step 3. Turn on the infrasonic wave generating device, and launch infrasonic waves starting from 1Hz to the building;

[0025] Step 4. The resonator continuously detects and records the vibration frequency and intensity of the building;

[0026] Step 5. Compare the vibration intensity and vibration state of the building after each infrasonic wave is emitted, and select the largest set of data;

[0027] Step 6. Start blasting and demolition: launch the infrasonic wave with the highest vib...

Abstract

The invention discloses a building blasting device based on an infrasonic wave resonance principle. The building blasting device comprises a resonance detector (1), a building (2) subjected to demolition blasting , an infrasonic wave emitter (3) and infrasonic waves (4); the resonance detector (1) is mounted on the demolition blasting building (2), and the infrasonic wave emitter (3) is placed on the ground away from the building over the collapsing safety distance; the infrasonic wave emitter is turned on and emits the infrasonic waves (4), gradually enhanced with 1Hz as the beginning, to the building in an orientation manner; the resonance detector (1) continuously detects and records the vibration frequency and the vibration strength of the building; the vibration strength and the vibration state of the building (2) obtained after the infrasonic wave are emitted every time are compared, and demolition blasting begins; and the infrasonic wave emitter (3) is used for emitting the infrasonic waves (4) to the building, and vibration of the demolition blasting building (2) is more and more strenuous till demolition blasting is achieved. The collapse direction can be accurately controlled, the blasting vibration can be effectively reduced, and the collapse length range of the building can be reduced.

Description

technical field [0001] The invention relates to a building blasting device, in particular to a building blasting device based on infrasonic resonance technology. Background technique [0002] Wuhan Blasting Company discloses a building blasting demolition method, in particular to a section-by-section directional tumbling blasting demolition method for a mixed structure building. The method comprises the following steps: pre-demolishing the wall body of a building to be demolished by blasting; setting a blasting incision at the bottom of the building; drilling a hole at the blasting incision to form a blasthole; charging the blasthole; The longitudinal axis and the transverse axis are divided into multiple detonation areas, and the detonation areas correspond to the detonation sequence; along the longitudinal direction from back to front, along the horizontal direction from one end to the other end or both ends to the middle, and the detonation area is bounded by the time-del...
