Demolition of a Eleven-storey Building and Five Fifteen-meter High Concrete Pots by Blasting

摘要：

The method of using definite directional blasting to demolish the frame structure building is introduced, and method election, parameters calculating, the election of detonating delay are presented in this paper. The results have some reference significance for the similar engineerings.Hue print: (1) The building and concrete pots are ignited by the same time; (2) In order to ensure the support intensity, the load-bearing columns, which located in reverse of the main building, only are destroyed in the small scope, the bearing wall do not be destroyed;(3) The concrete crossbeam between the main building with the vice-building must be cut off entirely by the pre-processing; (4) The tapholes of concrete pots are disposed properly before the ignition.
