基坑工程监理细则ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦

ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
土方ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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。ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
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：ƒÿñÖÂM^0bbs.3c3t.comp÷ïÁ¦
