Construction Technique of Excessive Length Mass Concrete Foundation Slab at Qingdao Intermediate People's Court General Building

抗裂防渗是地下室底板大体积混凝土施工中的主要技术难题,结合工程实例,针对近海工程地下水压大、雨季施工及具体结构特点,从裂缝预控措施、施工技术措施、施工工艺等环节出发,系统介绍了设计、材料、配合比、施工、温度监测等方面所采取的施工措施,工程实践表明所采取的措施有效地保证了工程质量.

The technique problem of anti-cracking and impermeability of the sub-slab concrete in basement is a hard nut to crack. In combination with the engineering illustration and the paper aims at the underground hydraulic pressure of inshore engineering which is high, construction in rainy seasons, the characteristics of structure, crack prevention performance and construction technology, and systematically introduces the measures of design, material, mix proportion, construction, the gradient of temperature monitor etc. The engineering practices have show that it is effective to ensure the quality of engineering structure.
