冬季施工安全注意事项

Release time:2019-05-31Browse:4432


冬季施工点多面广,危险因素很多,安全任务艰巨。冬季天气干燥、多风多雪天气,不利于工程施工。针对这些实际情况,认真做好防人身事故、防火灾、防爆炸、防冻、防中毒和防交通事故的六防工作,预防各类事故的发生,确保施工安全。

1、要在防护设施周边设置醒目的预防高空坠落的安全警示牌。施工现场搭设的防护棚、防护栏杆等防护设施,必须按照《建筑施工安全防护设施标准》的要求,使用定型化、工具化的安全防护设施。脚手架与建筑物之间距离过大超出规范要求的,要采取安全防护措施。

3、遇到雨雪等恶劣天气时,要及时清除施工现场的积水、积雪,严禁雨雪和大风天气强行组织施工作业。

 

二、防火灾事故

2、消防设施及器材应做到齐全、完好和能用。在入冬前进行一次全面检查。

4、加强冬季取暖的统一管理,宿舍的公用取暖设施应设专人管理,严禁在宿舍内使用电炉或采用明火取暖。

1、防止施工场地、运输道路积水和结冰,造成安全隐患;脚手架,脚手板有冰雪积留时,施工前应清除干净。

3、应由专业电工负责安装、维护和管理用电设备,严禁其它人员随意拆、改装电气线路。

5、霜、雪过后要及时清扫作业面,对使用的临时操作架和临边防护设施必须由安全管理人员检查合格后才能继续使用,防止因霜、雪和场地太滑而引起高处坠落事故。

 

四、防中毒

2、封闭的场所必须有通风换气措施。燃气热水器必须安装在通风良好的地方,使用时必须保持通风。

1、广泛开展冬季行车安全教育,落实防冻、防滑、防雾和防火等具体措施,进一步提高驾驶员的冬季行车安全意识。

3、认真贯彻落实车辆的各项管理制度,做好车辆的换季保养工作,要采用符合冬季使用的防冻液、润滑油和制动液、发动机和散热器外壳要安装防寒保温罩,尤其是刹车系统、转向系统、灯光系统必须完好可靠,确保车辆处于良好的技术状况。

"三先确保行车安全。

6、遇严重冰雪路面要求加装防滑链、车辆行进中应保持行车距离,并适当拉长车距降低车速,防止尾追事故的发生。

 

七、冬季施工要求

2、已确定进入冬季施工的项目,在冬季施工材料、设备落实后,要保证施工力量,做到连续施工,避免造成不必要的浪费。

4、技术培训。进入冬季施工前,各施工单位要对施工管理人员、测温人员和操作人员进行培训,考核合格后方可上岗。

6、冬季施工计划管理,进入冬季施工前,将冬季施工准备工作项目和用工纳入生产计划和用工计划,并结合各级施工方案,统一安排生产计划。冬季施工过程中严格按《冬季施工技术规定》中的要求和冬季施工方案确定的原则和施工方法进行施工。

8、要加强安全消防管理、冬季施工检查、冬季施工管理工作。

1)土方工程:安排在冬季开挖的土方工程,为防止土壤冻结,可根据气温条件翻松表土或覆盖保温材料,对土壤进行保温防冻;开挖冻土时,确定开挖方法和使用机具的种类,并制定安全措施;冬季挖槽,对暴露出来的自来水管或其他通水管,应根据需要采取相应的防冻措施;冬季土方回填每层铺土厚度比常温施工时减少160——200mm。基坑回填土中冻块含量不得超过回填总体积的150mm,铺填时,冻土块应均匀分布,逐层压实;沟槽回填土的压实度应逐层检查,严格按照规范的标准。

(80℃,砂的温度不能超过10——20cm。

5天稳定低于70%;混凝土的冬季施工应对原材料加热、搅拌、运输、浇灌和养护,要进行热工计算,应按时施工;混凝土的材料配置冬季施工的混凝土,应优先使用硅酸盐水泥、普通硅酸盐水泥。对于混凝土,水泥强度等级不宜低于0.6,用水量在满足操作要求的条件下应尽量减少。

9、冬季施工材料的保管。冬季施工的材料应根据施工进度计划提前备料,到场的材料应注意防冻,必要时覆盖电热毯等加热装置,定期检查管材、砖、砂浆等材料的情况,如果发现问题及时解决,以确保施工质量。
