摘要
本文针对某引黄闸工程中的钢筋混凝土扭曲面翼墙施工技术展开了详细的分析与应用研究。工程中应用了高性能混凝土(HPC),通过加入0.8%的聚羧酸减水剂将水灰比控制在0.35,确保混凝土的流动性和抗压强度达到50 MPa。钢筋采用HRB400级螺纹钢筋,钢筋间距控制在100 mm,并通过三维建模进行精确定位。模板设计采用建筑信息模型(BIM)技术,通过三维建模和数控切割技术,模板尺寸精度控制在±0.5 mm,安装精度实测偏差为±1.9 mm。通过分段分层浇筑及高频振捣技术,确保混凝土密实度和表面平整度。最终的实测数据显示,结构的抗冲刷性能和耐久性优良,验证了扭曲面翼墙施工技术在复杂水利工程中的可靠性。
This study conducted a detailed analysis and application research on the construction technology of reinforced concrete twisted surface wing walls in a certain Yellow River diversion gate project.High performance concrete(HPC)was applied in the project,and the water cement ratio was controlled at 0.35 by adding 0.8%polycarboxylate superplasticizer,ensuring that the flowability and compressive strength of the concrete reached 50 MPa.The steel bars are made of HRB400 grade threaded steel bars,with a spacing controlled at 100 mm,and precise positioning is achieved through 3D modeling.The template design adopts building information modeling(BIM)technology,and the dimensional accuracy of the template is controlled within±0.5 mm through 3D modeling and computer numerical control(CNC)cutting technology.The measured installation accuracy deviation is±1.9 mm.Through segmented and layered pouring and high-frequency vibration technology,the compactness and surface flatness of the concrete are ensured.The final measured data shows that the structure has excellent anti erosion performance and durability,verifying the reliability of the twisted wing wall construction technology in complex hydraulic engineering.
