问题 问答题

背景材料:

某二级公路,全场9.32KM,全路段的石方爆破主要集中在K2+300~K2+420,

K3+240~K3+480,K6+450~K6+490,K8+590~K8+810,爆破路段附近无重要建筑物,施工单位编制了“公路路堑石方爆破工程专项施工方案”,专项施工方案编制的主要内容包括工程概况、编制依据、施工计划、施工工艺技术、劳动力计划等。施工单位编制的爆破施工流程为:施爆区现场勘测→爆破计划及设计审批→配备专业施爆人员→施爆区施工放样→用机械清除施爆区强风化岩石→A→八婆婆器材检查与试验炮→炮孔检查与废渣清除→装药并安装引爆器材→布置安全岗和施爆区安全员→炮孔堵塞→撤离施爆区内人→起爆→B→解除警戒→测定爆破效果(包括飞石震动波对施爆区内、外构造物造成的破坏和损失)。施工单位编制的爆破施工方案为:根据爆破工程量要求,综合考虑区地形、地质、环境条件、设备和技术条件等,石方爆破自上而下分台阶逐层进行,采用电力起爆,爆破高度小于5m时,用浅眼爆破法分层爆破,分层高度2~3m;爆破高度5~10m时,用深孔爆破法一次爆破到设计标高;爆破高度超过十米时,分台阶进行深孔爆破,工作台阶分层高度定为5~10m,永久边坡采用光面爆破的方法进行处理。

台阶爆破参数示意图如下:

施工单位根据施工爆破方案、工程量、施工进度计划、施工质量要求、现有机械技术状况等配置了机械设备,石方爆破主要机械设备如下表:

在施工爆破现场,工班长要求操作人员严禁穿化纤衣服,手机必须处于静音状态,堵塞材料应采用钻孔的石渣、粘土、岩粉等,堵塞长坡严格按照爆破设计进行,不得自行增加药量或改变堵塞长度,如需调整,应征得现场技术人员和监理工程师的同意并做好变更记录。

补充专项施工方案编制的主要内容。
