Construction method for shield to pass through municipal bridge area at short distance
The invention discloses a construction method for a shield to pass through a municipal bridge area at a short distance. The construction method comprises the steps of surveying the engineering general situation of the shield to pass through the municipal bridge area; performing model selection and detection evaluation on the shield tunneling machine; performing test section tunneling to determine overall tunneling parameters in the crossing process; performing protection on the municipal bridge crossing area; controlling the tunneling process of the shield underneath passing through the municipal bridge area; in the crossing process, performing shield tunneling machine grouting and muck improvement; and performing construction process monitoring and starting an early-warning system. And in the tunneling process, all-directional accurate control and settlement monitoring early warning are carried out. In the construction process, normal traffic operation of the ground of the crossing area is not affected, it is also guaranteed that settlement generated when the shield crosses the municipal bridge area in a short distance is within a reasonable range, and the construction process is safe. According to the method, through innovation of the construction step sequence and the construction system, the engineering risk is reduced, the safety and stability of the construction process are improved, and the method has large reference value for similar engineering in different complex environments.
本发明公开了一种盾构近距离穿越市政桥区的施工方法，包括步骤：勘察盾构穿越市政桥区工程概况；盾构机选型及检测评估；进行试验段掘进确定穿越过程的总体掘进参数；对进行穿越市政桥区实施保护；盾构下穿市政桥区掘进过程控制；穿越过程中盾构机注浆和渣土改良；施工过程监测及预警系统。掘进过程中进行全方位精准控制和沉降监测预警。施工过程中既未影响穿越区域地面正常交通运行，也保证了盾构近距离穿越市政桥区所产生的沉降在合理范围内，施工过程安全。本方法通过施工步序和施工体系的创新，降低了工程风险，提高施工过程的安全稳定性，对于不同复杂环境下的类似工程具有较大参考价值。
