自密实混凝土用于异形、水平钢管或钢筋密集等部位时,压注难度较大,质量难以保证。本文针对徐明高速公路11标带加劲板水平钢管的自密实混凝土施工,通过现场试验,选择自密实混凝土的最佳配比,掌握施工工艺,有效降低了自密实混凝土的压注施工难度,提高了工程施工质量。 Self-compacting concrete for shaped, horizontal steel or steel intensive parts, the pressure injection difficult, difficult to guarantee the quality. In this paper, aiming at the self-compacting concrete construction of horizontal steel pipe with 11 standard stiffened plates in Xu-Ming Expressway, the optimal proportion of self-compacting concrete is selected through field test and the construction technology is mastered, which effectively reduces the difficulty of pressure-injection construction of self-compacting concrete The construction quality.
