丹江口电厂2×800kW小电站厂房爆破拆除要求防止爆破震动、个别飞石及冲击波对周围建筑物和设施造成危险,控制爆破振动对大坝的影响。参建各方技术人员根据待拆厂房的结构特点、周围环境及爆破拆除要求,经过反复计算、论证,决定采用不同炸高差和时间差方法实现定向向右倒塌的爆破设计方案。方案以保障周边设施安全为重点,优选了爆破参数,制定了爆破振动控制、爆破飞石控制、减小空气冲击波等多项爆破安全技术性措施,保证了框架结构厂房定向爆破一次性成功,且周围建筑物及设施安全。
Danjiangkou Power Plant 2 × 800kW small power plant blasting demolition requirements to prevent blasting vibration, individual flying stones and shock waves on the surrounding buildings and facilities dangerous to control the impact of blasting vibration on the dam. According to the structural characteristics of the plant to be demolished, surrounding environment and blasting demolition requirements, technical personnel from all parties participating in the project decided to adopt different blast height difference and time difference methods to realize the blasting design scheme with right-direction collapse after repeated calculations and demonstrations. In order to ensure the safety of surrounding facilities, the blasting parameters are optimized, a number of blasting safety technical measures such as blasting vibration control, blasting fly-stone control and air blast reduction are formulated to ensure that the directional blasting of the frame structure factory is successful at one time, Buildings and facilities safety.
