【简答题】
某水闸共10，每净宽10.0m，底板厚1.6m，闸室总宽112.8m，顺水流长16.0m；闸室及翼墙底板基础采用水泥土搅拌桩处理。其主要工程内容有： ①地基与基础。 ②闸室段（土建）。 ③上游联接段。 ④下游联接段。 ⑤消能防冲段。 ⑥交通桥（工作桥）。 ⑦金属结构及启闭机安装。 ⑧启闭机房和桥头堡。 事件一：水泥土搅拌桩在施工前进行了2根工艺性试验桩，确定了施工参数。 事件二：水泥土搅拌桩施工完成后，施工单位对基坑进行了开挖，按规范要求对水泥土搅拌桩进行了检测。检测合格后，施工单位组织项目法人、监理单位、设计、质量监督、运行管理等单位组成联合小组，共同检查核定其质量等级并填写签证表。 事件三：水闸闸墩施工正值高温季节，为此，施工单位采取了多项温控措施保证混凝土施工质量。 事件四：闸室段分部工程完成后，施工单位对闸室段分部工程混凝土试件抗压强度果进行了统计分析，其中C20混凝土取样30组，最小强度为23.5，强度保证率为96%，离差系数为0.14。 事件五：本工程共划分为1个单位工程，单位工程完成后，监理单位组织项目法人、设计、施工、运行管理、质量监督等单位组成外观质量评定小组，现场进行工程外观质量检验评定，并将评定结论报工程质量监督机构核备。 事件一中的做法是否妥当？说明理由？
