混凝土结构的裂缝控制是一门多学科的系统工程,需要设计、施工、材料合理科学的配合,但即使采取了各种措施,建筑物出现裂缝仍是难以避免的。化学灌浆就是控制裂缝发展的一项专门技术。 随着近代规模建设的发展,国际上如日本、美国、法国、英国等国家在化学灌浆技术方面发展相当迅速,灌浆材料不下百种,配套机具设备日趋现代化。我国从50年代开始化学灌浆技术的研究,60年代在水电、煤炭、交通、建筑等部门进行现场 The control of cracks in concrete structures is a multi-disciplinary system engineering. It requires design, construction, and reasonable and scientific cooperation of materials. However, even if various measures are taken, cracks in buildings are still difficult to avoid. Chemical grouting is a specialized technique for controlling the development of cracks. With the development of large-scale modern construction, countries such as Japan, the United States, France, and the United Kingdom have developed rapidly in terms of chemical grouting technology, and grouting materials have been reduced to less than 100 kinds. Supporting machine equipment has become increasingly modern. China began research on chemical grouting technology in the 1950s and in the hydropower, coal, transportation, and construction sectors in the 1960s.
