Controlled blasting technology and damaged control measures of the large cooling tower
Abstract：The power plant cooling tower demolition work is mostly carried in the case of electricity generation,thusly it is an important problem to ensure the safe use of surrounding buildings and equipment as well as the normal operation of equipment.The best blasting gap parameters are the key to control the collapse of the cooling tower,which depends on theoretical calculation,engineering practice and blasting tests.Millisecond subsection blasting can reduce the speed of the air shock wave in the collapse.Pre-opening damping skylight is one of the best ways to effectively reduce the vibration generated by touchdown becanse it can destroy the integrity of the tower and make the cooling tower collapse,in a soft landing state.Pre-opening leak skylights in the opposite direction of the collapse can reduce the impact of the damage of the air shock wave in the collapse.The successful application of the above measures provides a reference and a guidance for similar projects.
