摘要
为确保南庄镇南片区排污主干管重点保护段顶管能安全穿越长距离路面河道,维护土层结构稳定,避免道路出现大面积坍塌和沉降等间题,不留后续安全隐患,文章介绍了该段顶管的优化施工方案,给出了相应的设计计算方法和施工措施,可供类似顶管工程参考。
In order to ensure that the pipe jacking of the key protection section of the main sewage pipe in the south area of Nanzhuang Town can safely cross long-distance pavement channels,maintain the stability of the soil layer structure,and avoid problems such as large-scale collapse and settlement of the road,leaving no subsequent safety risks,the article introduces the optimized construction scheme of the pipe jacking section provides corresponding design calculation methods and construction measures,which can be used as a reference for similar pipe jacking projects.
