摘要
结合实际施工案例,阐述了超大截面矩形顶管施工设备、管节、全自动测量、全自动注浆、全自动沉降监测等施工控制参数及技术措施,分析了超大截面矩形顶管后顶力、轴线水平和高程偏差、地面沉降量的变化规律,为今后此类工程施工提供指导与参考。
Combined with actual construction cases,the construction control parameters and technical measures of super-large rectangular pipe jacking construction equipment,pipe joints,automatic measurement,automatic grouting,and automatic settlement monitoring are explained,and the rear jacking force of super-large rectangular pipe jacking is analyzed.The variation law of axis level and elevation deviation,and ground subsidence provide guidance and reference for the construction of such projects in the future.
