某堤防工程总长为15.30km,其中新建堤防2km,起始桩号为K10+500,终止桩号为K12+500,堤身高度6.5m,按三十年一遇的防洪标准设计,主要建设内容有堤身清表、老堤加高培厚、新堤身土方填筑、填塘固基等。施工过程中发生如下事件:

事件一:工程开始前,施工单位对土料场进行了充分调查,选择具有代表性的黏性土进行碾压试验,选取三种不同的土料含水量,根据选定的碾压机械确定了含水量等土料填筑压实参数。

事件二:为加快工程进度,施工单位对新建堤防分两个作业段同时进行分层施工,每个工作面长度为1km,与老堤防接坡坡比按1:2控制。

事件三:监理机构根据料场土质情况、本工程设计标准和相关规定,分别提出新堤身土方填筑、老堤加高培厚施工土料填筑压实度、压实度合格率控制标准。

事件四:应项目法人申请,竣工验收主持单位组织了工程竣工验收会议。竣工验收委员会由竣工验收主持单位、有关地方人民政府和部门、有关水行政主管部门、质量和安全监督机构、项目法人、勘测、设计、监理、施工、主要设备制造商、运行管理等单位的代表以及有关专家组成。

指出事件二的不妥之处,并改正。两个作业段同时进行分层施工应注意哪些要点?

答案

参考答案:

与老堤防接坡坡比按1:2控制不妥,应缓于1:3。两个作业段同时进行分层施工,层与层之间分段接头应错开一定距离,各分段之间不应形成过大的高差。
