摘要
以黄冈遗爱湖截污疏浚DN2400管道工程为例,从技术、经济与安全角度对明挖法和手掘式、泥水平衡式、土压平衡式顶管法四种施工方案进行了对比。对低覆土厚度下的回填土地层中采用土压平衡顶管施工存在的有关问题及对策进行了探讨。
For the Huanggang Yiai Lake interception in dredging DN2400 pipeline engineering as an example,the author compares four construction schemes of the cut and cover method,the hand-dug-style,mud balanced,earth pressure balance pipe jacking method from technical,economic and safety aspects.The author also discusses some problems and countermeasures of earth pressure balance pipe jacking method under shallow backfill strata.
