市政深埋污水管道敷设施工方案比选

Comparison and Selection of Construction Schemes for Municipal Deep Buried Sewage Pipeline Laying

以某工程污水管为例,进行安全和经济性方面的比选分析,分析结果表明:埋深小于6.5m时,钢板桩支护开挖安全风险较小,造价合理;埋深大于6.5m时顶管施工方案的安全性较高,造价合理。

This paper takes a project sewage pipe as an example to carry out comparative analysis in terms of safety and economy. The analysis results show that when the buried depth is less than 6.5 m, the safety risk of steel sheet pile support and excavation is small and the cost is reasonable. When the buried depth is more than 6.5 m, the pipe jacking construction scheme has higher safety and reasonable cost.
