| 中文摘要: |
| 地下室砼结构由于受到地质状况、地下水位变化、上部结构荷载变化等因素的影响,较易出现开裂渗水,影响结构的使用功能.从施工段的划分、模板工程、大体积混凝土工程施工等方面做了阐述,通过多层胶合板模板体系来保证砼结构成型质量,在底板大体积砼施工中,控制砼入模温度、分层振捣、测温及监控等措施来保证砼密实度,提高地下室砼结构的抗渗效果,更好的保证工程质量. |
| 英文摘要: |
| Dehiscence and leak is common scene in basement construction due to the influences of geological condition,groundwater level variation and superstructure load variation,etc.As a result,the utilization of basement is impaired.This paper elaborates on noteworthy details in division of construction section,formwork,and concrete work construction.Multi-plywood formwork system is adopted to ensure forming quality,temperature control and layered vibration in floor construction to ensure concrete compactness.Thus the impermeability of basement concrete structure is improved and better construction quality is ensured. |
