用于TBM的钢筋混凝土同步3D打印衬砌装置及方法
By using a 3D printing device for reinforced concrete in TBMs, combined with finite element analysis and real-time temperature monitoring, the problem of the inability of steel bars and concrete to be printed synchronously in traditional tunnel lining construction has been solved. This has enabled efficient and automated synchronous molding of reinforced concrete, improving the overall integrity and quality stability of tunnel construction.

Abstract
本发明公开了一种用于TBM的钢筋混凝土同步3D打印衬砌装置及方法，属于增材制造领域。包括施工轨道车、激光雷达、混凝土3D打印模块、钢筋激光打印模块和控制模块；控制模块根据激光雷达扫描的隧道形貌数据构建衬砌三维模型，并通过有限元分析提取主应力迹线，生成以应力导向为原则的钢筋布置路径与混凝土打印轨迹；钢筋激光打印模块与混凝土3D打印模块分别沿路径和轨迹同步打印，控制钢筋层高高于混凝土层；基于热力学相机获取的监测信息动态调节钢筋激光打印模块的激光功率与送丝速度，将温度波动控制预设偏差以内。本发明能够在TBM施工环境下实现钢筋混凝土同步增材成型，具备高度自动化、构造灵活性强和全过程可监测的特点。
