分析了钻井预制井壁混凝土早期裂缝的原因,从优化混凝土配合比、优化搅拌工艺、优化浇筑工艺等方面,阐述了早期混凝土裂缝控制技术途径,从而保证混凝土施工质量。
The reasons of early cracks in prefabricated wellbore for drilling are analyzed. The ways of controlling concrete cracks in early stage are expounded in terms of optimizing mix ratio of concrete, optimizing mixing process and optimizing pouring process, so as to ensure the quality of concrete construction.
