14、渣等缺陷。4.4塔吊的拆卸步骤4.4.1塔吊的拆除程序与安装程序相反。4.4.2塔吊自降标准节至最底，降级作业必须严格按说明书的规范进行。4.4.3拆除塔吊卷扬钢丝绳及配重：将小车行至臂跟，固定在臂架上，卸下前后钢丝绳，后绳绕在小车卷筒上，卸下前绳。切断电源，拆除电缆。吊下配重。4.4.4拆除起重臂：汽车吊吊住起重臂，用张紧器拆卸拉杆，落下整个臂架，并将其放在地面。4.4.5拆除塔吊平衡臂。4.4.6拆除塔帽：拆除回转；拆除塔吊的顶升套架。4.4.7拆除塔吊剩余标准节及过度节。4.4.8拆除节，需用气焊将预埋于建筑底板的节预埋割除，以免影响建筑装修。4.4.9清点物件，运出施工现场。5、 群塔
15、作业5.1群塔作业防碰撞措施5.1.1塔吊在初期定位安装、中期使用（顶升）以及后期拆除都应考虑到可能发生的碰撞事故，为避免塔吊间发生碰撞事故，保证塔吊正常、安全地使用，群塔作业防碰撞措施尤为重要。5.1.2塔吊在水平方向的防碰撞措施 考虑到现场周围环境的限制，并结合施工的需要，确定塔吊在现场的布置，在塔吊定位时已把各塔之间的距离均大于相关的塔吊臂长。这样就保证了安全规程中：三台塔吊之间的最小架设距离应保证处于低位的塔吊臂架端部与处于高位塔吊的塔身之间有2米距离由此，可以解决三台以上塔吊之间低位塔吊的起重臂与高位塔吊的塔身发生碰撞问题。5.1.3 塔吊在垂直方向的防碰撞措施（1）低位的塔吊的起重
16、臂与高位塔吊起重钢丝绳之间防碰撞措施 由于受施工需要的影响，有可能发生低位的塔吊的起重臂与高位塔吊起重钢丝绳的碰撞事故。为杜绝此类事故发生，必须对每一台塔吊的工作区进行合理划分，避免出现塔吊交叉工作区。同时，必须配备有合格操作证的、经验丰富的信号指挥工，确保指挥塔吊回转作业时，低塔的起重臂不碰撞高塔的起升钢丝绳。当现场风速达到5级风时，相当于风速达到10.813.8米/秒时，塔吊必须停止作业。另外，要配备操作熟练、有责任心的塔吊司机为现场服务，塔吊在每次使用后或在非工作状态下，将塔吊的吊钩升至顶端。 （2）高位塔吊的起重臂下端与低位塔吊最高部件防碰撞措施由于相邻的回转面有交叉区域，所以低位塔吊
17、的起重臂与高位塔吊的起重臂有可能发生碰撞。由各塔吊初装吊钩高度可知各塔吊钩高度差均大于6米，这样就保证了安全规程中：三台塔吊之间架设高差处于低位塔吊的较高位置的部件（塔顶，拉杆等）与处于高位塔吊的最底位置部件（已升至最高的吊钩、配重等）间的垂直距离不得小于2米。5.1.4塔吊与现场周边建筑及设施的防碰撞措施施工现场周围有建筑物，塔吊设计定位时已避开这些建筑。为稳妥起见，在塔吊现场定位时，必须对其复核。在实际施工中，还要密切关注现场以外的情况，塔吊初次顶升要超过临近低层建筑物的高度，还要注意周边情况尤其是现场工人和车辆，还要避让附近电力及通讯设施，以免造成不必要的伤害或破坏。综上所述，本工程在塔
