大型设备基础混凝土裂缝防治大型设备基础混凝土裂缝防治protection and treatment for crack during construction of large volume foundation  daxlng shebe一Jiehu hunningtu}iefeng fangZhl大型设备蓦础混凝土裂缝防治(proteetion。ndtreatment for eraek during eonstruetion of large vol-ume foundation)在冶金工厂建设中,设备基础的混凝土约占混凝土工程总量的60%以上。随着冶金设备向大型化发展,设备基础的体积愈趋庞大。以中国上海宝钢工程为例,容积为4063m“的1号高炉,其基础混凝土工程量约为600om3;3座3oot转炉的基础底板的混凝土工程量将近700om“。施工时每次混凝土的浇筑量多在looom3以上。施工中,水泥水化热引起混凝土浇筑块体内部温度和温度应力剧烈变化,以及混凝土的凝结收缩,都会引起对结构整体性、耐久性和强度有影响的混凝土裂缝。防止这种裂缝的产生和对已出现裂缝的有效治理是保证工程质量的关键之一。 裂缝原因和防止原则在大型设备基础的施工中,当混凝土内部温度变化和凝结收缩引起的变形受到约束时,浇筑块体内就要产生应力。当其中的拉应力超过混凝土材料的抗拉极限时就会出现裂缝。对变形的约束有两类情况:一是混凝土浇筑块体内部各质点间因变形量不同而产生相互牵制和影响,称为“自约束”;二是浇筑块体的变形受到外部物体(如地基、相邻结构、下部混凝土浇筑层等)的阻碍,称为“外约束”。 为防止裂缝的产生,应从以下几个方面考虑对策。(1)提高混凝土自身和混凝土结构的抗裂能力。施工中要严格控制材料和施工工艺,使结构质量完全符合设计和规范要求。(2)减少混凝土中的总发热量,降低水泥水化发热速率,合理调剂混凝土在凝结过程中的温度与湿度,以减小温度应力和收缩产生的应力。(3)减弱内、外约束的影响。(4)重视控制温度对防止裂缝产生的决定性作用,在基础施工的全过程中,按阶段进行温度应力分析,确定温度控制指标和技术措施。 沮控防裂措施包括基础设计、混凝土配制、混凝土浇筑与养护、施工中混凝土温度监测四个方面。 基础设计主要措施有:(1)基础混凝土的强度等级应为C巧一C25。(2)对独立的大型钢筋混凝土设备基础不设沉降缝、温度缝等永久变形缝。(3)当基础设置于岩石地基上时,在混凝土垫层上表面应设滑动层(可采用一毡二油构造),以减少地基对混凝土变形的约束。(4)基础配筋除应满足基础承载力及构造要求外,还要增配承受因水泥水化热引起的温度应力及控制裂缝开展的构造钢筋。 混凝土配制主要措施有:(1)选定混凝土配合比时,应在保证基础强度、耐久性和施工工艺要求的前提下尽量减少水泥用量,以降低混凝土的绝对温升值。
