某超高层建筑地下室大体积砼温度裂缝控制

本文以某超高层建筑地下室大体积砼施工为例,详细介绍和论述了大体积砼施工技术在实际工程中的运用情况及其效果。本工程从商品砼的质量控制、浇筑施工等方面采取科学的技术措施及严格的组织管理,并根据大体积砼温度裂缝控制验算结果,在现场测温监控、砼施工过程控制、保温保湿养护等方面采取一系列温控防裂技术措施,以保证地下工程结构的质量。实践证明,地下室大体积砼施工完毕后未出现有害裂缝,施工效果良好,可供类似工程参考。

A tall building in the basement of mass concrete cracks control the temperature

In this paper,a tall building in the basement of mass concrete construction,for example,introduced and discussed in mass concrete construction techniques used in the actual project and its results.This project from quality control of the commercial concrete,placing construction and other technical measures taken by the scientific and strict organization and management,and according to the mass concrete temperature crack control checking calculation result,temperature monitoring in the field of concrete construction process control,thermal insulation and other conservation temperature control technology has taken a series of measures to ensure the quality of underground engineering structures.Practice shows that the basement after the massive concrete cracks does not appear harmful,construction works well,for similar projects.
