某机电安装公司项目部承建的雨水管道工程管线总长为1000m，采用直径为600mm的混凝土管，柔性接口；每50m设检查井一座。管底位于距地表下4m，无地下水，采用挖掘机开槽施工。
该项目部根据建设单位对工期的要求编制了施工进度计划。编制计划时，项目部使用的指标见下表。
考虑管材进场的连续性和人力资源的合理安排，在编制进度计划时做了以下部署：
（1）挖土5d后开始下管、安管工作；（2）下管、安管200m后砌筑检查井；（3）检查井砌筑后，按四个井段为一组（200m）对沟槽回填。
项目部编制的施工进度计划见图2-7（只给出部分内容）。
工程实施过程中，挖土施工10d后遇雨，停工10d。项目部决定在下管、安管工序采取措施，确保按原计划工期完成。
遇雨后项目部应在下管、安管工序采取什么措施确保按原计划工期完成？
参考答案：
遇雨后项目部应在下管、安管工序采取增加人员、机械物资及资金的投人，实行二班倒或者三班倒的制度措施确保按原计划工期完成。
