基坑工程监理细则y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,

y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
1、在基坑(槽)或管沟工程等开挖施工中,现场受地形限制不宜放坡开挖并可能对邻近建(构)筑物、地下管线、永久性道路产生危害时,应考虑对基坑(管沟)进支护后再开挖。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
2、审查施工组织设计方案,根据支护形式、挖深、地质条件、施工方法、周围环境、工期、气候和地面。荷载等资料制定施工方案,环境保护措施、监测方案。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
3、土方工程施工前,审核降水、排水措施的设计方案,并对降水系统进行检查和试运转,当一切正常方可开始施工。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
土方y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
4、土方开挖的顺序、方法应与设计工况相一致,并遵循“开槽支撑、先撑后挖、分层开挖、严禁超挖”的原则执行。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
5、挖土时应分层进行,施工过程中基坑边堆置土方不能超过设计荷载,挖方时不应碰撞或损伤支护结构、降水设施。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
6、施工时,定时对支护结构、周围环境进行观察和监测,若出现异常情况应及时处理,待恢复正常后方可继续施工。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
7、开挖至设计标高后,应对基坑底进行保护,经验槽合格后方可进行垫土施工,对特大型基坑宜分区、分块挖至设计标高,分区、分块及时浇筑垫层。y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
8、基坑土方工程验收必须以确保支护结构安全和周围环境安全为前提,当设计有指标时,以设计要求为依据,若无设计指标则按下表规定执行:y/RG#ž=Cbbs.3c3t.com+ÔnÇø‘—,
