摘要
福州地铁5号线吴山站地层为淤泥、黏性土等不良地质,距离基坑边DN500次高压燃气管线在基坑开挖出现沉降,存在重大安全隐患,需对管线采取悬吊保护措施,通过监测数据表明,措施能够满足施工需要,保证施工的顺利进行。
The stratum of Wushan station of Fuzhou Metro Line 5 is bad geological area such as silt and cohesive soil.The DN500 high-pressure gas pipeline from the foundation pit is subsided in the excavation of the foundation pit.There are major safety hazards,and it is necessary to take suspension protection measures for the pipeline.Through the monitoring data,the measures can meet the construction needs and ensure the smooth progress of the construction.
