| 摘 要： | 为了确保复杂环境下2座90m高冷却塔能够安全拆除,对冷却塔进行了有效的预处理及安全防护.首先对冷却塔进行了预开定向窗和减荷槽,并应用第二强度理论对预处理后冷却塔的稳定性进行了安全校核,然后采用双层钢丝网夹一层草袋对爆破点进行直接防护,采取上部覆盖1层沙袋,并加盖1层竹笆或钢板的防护方式对周边的电缆线管等进行防护,并沿冷...

| Abstract: | For guaranteeing safety demolition of the two 90m cooling tower under complex surrounding,the effect pretreatment and security protection were done to cooling tower.Firstly,the cooling tower was done windowing and off-loading groove and the stability of cooling tower after pretreatment was check using the second strength theory.Then the direct protection of two hardware cloth layer with a straw bag was on the blast site,meanwhile,the indirect protection of a sandbag layer with bamboo basketry or armor plate... |
