丹江口电厂2×800kW小电站厂房的爆破拆除设计

Blasting Design to Dismantling the Danjiangkou 2×800kW Small Power Plant

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 plants require blasting to remove to prevent blasting vibration, shock and individual fly-rock of surrounding buildings and facilities pose a danger to control the vibration of the dam bursting. Participation parties to be demolished under the technical characteristics of the plant, the environment and require blasting to remove, through repeated basis, argues that the decision to bomb a different elevation and the time difference method to achieve the right direetional blasting the collapse of the design. Program in order to protect the safety of the surrounding facilities, focusing on the optimization of blasting parameters,developed a vibration control blasting, blasting Stone fly control, reduce air blast shock wave,and so on a number of teehnical seeurity measures to ensure the structural framework of plant blast targeted a one-time success,and the surrounding buildings Safety facilities and materials.
