浅谈大型渠道现浇混凝土衬砌
Elementary discussion on cast-in-situ concrete liner in large-scale canals
【摘要】 在材料及配合比一定的情况下,混凝土的密实度决定了混凝土的其他指标,如强度、抗渗、抗冻等。衬砌质量的判别标准有三:一是混凝土的密实度;二是混凝土的表面平整度,包括糙率;三是混凝土几何尺寸及位置。如何取得高质量的衬砌混凝土,决定于施工工艺。现就大型渠道衬砌施工这一问题做初步的探讨。
【Abstract】 Under the circumstance of definite mix proportion and raw materials, the compactness of concrete determines the other indexes in concrete, such as strength, impermeability, frost resistance and others. There are three kinds of standard to distinguish the quality of linen One is the compactness of concrete. The second is the surface leveling degree of concrete, including its roughness.The third is it’s measurement. It is the construction technique that decides how to get lining concrete with high quality. In this paper, the authors make a preliminary inquiry into the above-mentioned problem.
