某公司中标北方城市道路工程,道路全长1000m,道路结构与地下管线布置如图1所示:

施工场地位于农田,临近城市绿地,土层以砂性粉土为主,不考虑施工降水。

雨水方沟内断面2.2m×1.5m,采用钢筋混凝土结构,壁厚度200mm;底板下混凝土垫层厚100mm。雨水方沟位于南侧辅路下,排水方向为由东向西,东端沟内底高程为-5.0m(地表高程±0.0m),流水坡度1.5‰。给水管道位于北侧人行道下,覆土深度1m。

项目部对①辅路、②主路③给水管道、④雨水方沟⑤两侧人行道及隔离带(绿化)作了施工部署,依据各种管道高程以及平面位置对工程的施工顺序作了总体安排。

施工过程发生如下事件:

事件1:部分主路路基施工突遇大雨,未能及时碾压,造成路床积水、土料过湿,影响施工进度。

事件2:为加快施工进度,项目部将沟槽开挖出的土方在现场占用城市绿地存放,以备回填,方案审查时被纠正。

针对事件1写出部分路基雨后土基压实的处理措施。

答案

参考答案:

事件一雨季路基施工:(1)对于土路基施工,要有计划地集中力量,组织快速施工,分段开挖,切忌全面开挖或挖断过长。(2)挖方地段要留好横坡,做好截水沟。(3)填方地段施工,应留2%~3%的横坡整平压实,以防积水。处理措施为应将路床积水排干,对含水量过大的调料进行翻晒或换填,在接近最佳含水量时重新碾压,使得路基的压实度达到设计要求。雨季施工路基坚持当天挖完、填完、压完,不留后患。
