某项目采用人工挖孔桩钢筋笼配筋加钢绞线技术,因为钢绞线特有的物理性能——抗拉强度大,结合工程实际施工,钢筋笼加入适量钢绞线,有效的提高工程桩的整体抗拉性能,减少了钢筋使用量,实现了降本增效。并详细阐述了该技术的施工工艺、技术要点和作业的具体步骤,实践证明,该技术的施工具有:机具简单、易操作、对周围环境及建筑物影响小、质量安全可靠、工期短、造价低等优点。 Because of the unique physical properties of steel strands - large tensile strength, combined with the actual construction of the project, adding a suitable amount of steel strands to the steel cage to effectively improve the engineering pile The overall tensile properties, reducing the amount of steel to achieve cost reduction and efficiency. The construction technology, technical points and concrete steps of the technology are expounded in detail. Practice has proved that the construction of the technology has the following features: simple implement, easy operation, little impact on the surrounding environment and buildings, safe and reliable quality, short construction period, Low advantage.
