问题 单项选择题

分节制作、分次下沉的沉井,前次下沉后进行()施工。

A.降水排水

B.后续接高

C.清理刃脚

D.纠偏调向

答案

参考答案:B

解析:

考点为沉井施工内容,属于实践型考题。

考试用书中有关内容综述如下:

分节制作、分次下沉的沉井后续接高施工内容:包括钢筋安装(钢筋采用分节、分片制作,整体吊装)、模板安装(如采用翻模法)、混凝土浇筑(一次浇筑到位)。后续接高施工要求:应验算接高后稳定系数等,并应及时检查沉井的沉降变化情况,严禁在接高施工过程中沉井发生倾斜和突然下沉;后续各节的模板不应支撑于地面上,模板底部应距地面不小于1m。设计无要求时,混凝土强度应达到设计强度等级75%后,方可拆除模板或浇筑后节混凝土。混凝土施工缝处理应采用凹凸缝或设置钢板止水带,施工缝应凿毛并清理干净;内外模板采用对拉螺栓固定时,其对拉螺栓的中间应设置防渗止水片;钢筋密集部位和预留孔底部应辅以人工振捣,保证结构密实。沉井每次接高时各部位的轴线位置应一致、重合,及时做好沉降和位移监测;必要时应对刃脚地基承载力进行验算,并采取相应措施确保地基及结构的稳定。

由此可见B选项正确。
