土压平衡顶管下穿市政主干道施工技术

Pipe Jacking Construction Technology Underpass Municipal Main Road Based on Soil Pressure Balance

结合工程实例,分析了土压平衡顶管施工时的管道埋深对道路路基的影响及顶管下穿道路时的沉降量,并就土压平衡顶管施工下穿市政主干道的施工技术要点展开了详细的研究,以保证城市主干道周围建筑及设施安全,减少顶管施工对主干道交通的干扰,提高顶管施工效率。

Combined with engineering examples,the influence of pipe buried depth on road subgrade and the settlement when pipe jacking passes through road under soil pressure balance construction are deeply analyzed,and the key points of construction technology ofthe municipal main road under soil pressure balance pipe jacking construction are studied in detail,so as to ensure the safety of buildings and facilities around the main road,reduce the interferenceofpipejacking construction on the main road traffic,and improve the efficiency of pipejacking construction.
