随着高层建筑工程、框架结构混凝土浇筑工程、钢筋混凝土工程项目不断增多,提高了对混凝土工程施工速度的要求,混凝土泵送施工技术得到普及和应用。研究改进提高泵送混凝土施工的工艺技术,提高施工人员和管理人员的泵送混凝土施工的操作与管理知识、技能,是提高建筑工程施工水平和施工质量的切实需要,也是建筑工程施工采用泵送混凝土施工普及的需要。现主要阐述了泵送混凝土施工中的一些技术要求和温度裂缝存在的问题并进行原因分析,提出控制和防止温度裂缝的有效措施,提高泵送混凝土浇筑质量。
With the high-rise building projects, the framework of concrete pouring works, reinforced concrete projects continue to increase, raising the speed of the concrete construction requirements, concrete pumping construction technology has been universal and application. Research to improve and improve the pumping of concrete construction technology, improve the construction and management of pumping concrete construction operation and management knowledge and skills, is to improve the construction level and construction quality of the practical needs, but also the construction of pumping Concrete construction needs universal. This paper mainly expounds some technical requirements and problems of temperature cracks in the construction of pumping concrete and analyzes the causes, and puts forward effective measures to control and prevent temperature cracks and improve the pouring quality of pumping concrete.
