武汉长江隧道是国内第一条采用盾构施工的过江隧道,水下环境复杂,施工难度大,通过对武汉过江隧道盾构施工过程中实施的带压进仓技术的总结,描述泥水盾构水下施工过程中带压进仓的操作步骤、技术要点、注意事项等,分析水下带压进仓的风险和防范措施;同时对进仓过程中相关监测措施和地面保障措施进行介绍,强调前期准备工作的重要性以及相关技术参数的设置、调整方法等,对其它类似的水下施工具有较强的参考性和借鉴性。
Wuhan Yangtze River Tunnel is the first cross-river tunnel with shield construction in China. The underwater environment is complex and the construction is difficult. Through the summary of the pressurized bunker technology used in the construction of shield tunnel in Wuhan Cross-river Tunnel, Construction of underwater construction process with pressure into the warehouse operating steps, technical points, precautions, etc., to analyze the risk of underwater pressure into the warehouse and preventive measures; the same time, the relevant monitoring measures into the warehouse and ground protection measures are introduced, Emphasize the importance of early preparations and related technical parameters of the setting, adjustment methods, for other similar underwater construction has a strong reference and reference.
