泵送混凝土不仅能提高混凝土性能,而且机械化程度高、浇筑速度快。特别能满足水闸工程度汛前混凝土浇筑量大、工期紧的要求,经济、社会效益显著。但淮河流域水闸工程实践表明,由于温度、湿度变化引起泵送混凝土的裂缝问题普遍存在,影响结构的抗渗性、耐久性及外观。本文主要分析泵送混凝土在水闸工程中运用存在的一些问题并提出防范措施。 Pumping concrete can not only improve concrete performance, but also a high degree of mechanization, pouring speed. In particular, to meet the sluice engineering flood season before the floodcrete volume, tight schedule requirements, economic and social benefits significantly. However, engineering practice of sluices in the Huaihe River Basin shows that the problems of cracking of pumped concrete due to temperature and humidity changes are widespread, affecting the impermeability, durability and appearance of the structure. This paper mainly analyzes some problems existing in pumping concrete in sluice project and puts forward some countermeasures.
