Currently, most of building is all built using concrete, common side during being removed to entire building room
Method are as follows: three kinds of forms such as mechanical removal, demolition blasting and manual demolition.Demolition blasting is generated using explosive in instant of detonation
High temperature, high pressure gas do work to medium, carry out brokenness to building or toppling property is demolished;Usually in Government-Leading, peripheral ring
Border is preferable, coordinates relatively small difficulty, uses in the case where Yi Yinqi media and masses' concern, in the more harsh city of condition
City business district, relatively fewer use.Manual demolition, be by by hand plus some simple tools (such as drill rod, hammer, air drill,
Lever Blocks, wirerope etc.), it is struck mainly by hammer, rod sled, is disintegrated with physical strength to building implementation with worker, is crushed to reach and tear open
The purpose removed.Mechanical removal, long-armed tear open building machine (long-armed hydraulic shear) is removed in city is removed more generally, low mainly in
Layer building.
But it when being removed for high-rise cast-in-place concrete building, is especially built more than 30 meters, is not allow mainframe
Upstairs, and skyscraper periphery usually has other houses to tool, and mechanical removal and demolition blasting at this time can not fit
Answer this demand.For conventional direct cutting disassembling, it is uneven not only to occur load during cutting, malformation,
Vibration is big, crack occurs, results even in cave-in accident, causes casualties.
