摘　　要：沟槽开挖与支护是市政道路排水管道工程中的重要施工项目,其施工质量直接关系到整体工程的质量。因此对于施工技术与工艺的研究具有一定价值,为此提出市政道路排水管道沟槽开挖及支护施工技术研究。根据市政道路工程实际情况,对沟槽开挖与支护施工进行策划,在施工现场进行测量放线和清表处理,采用“纵向分段,纵向分层,边挖边支护”的方法进行排水管道沟槽开挖,利用拉森钢板桩对沟槽支护。实例分析结果表明,排水管道沟槽开挖施工中地表水平位移和施工后地表沉降均未超出最大限值,符合施工质量验收规范。设计技术能够有效保证施工质量,在市政道路工程领域具有广阔的应用前景。Trench excavation and support is an important construction project in the municipal road drainage pipeline engineering,and its construction quality is directly related to the quality of the whole project.Thevefore,the study of construction technology and technology has certain value,so the research of trench excavation and support of municipal drainage pipe is proposed.According to the actual situation of municipal road engineering,plan the excavation and support construction of the grooves,and measure the line and clear the table in the construction site,the method of“longitudinal section,longitudinal stratification,digging and supporting”is to excavate the drainage pipe trench,and the Laren steel sheet pile is used to support the trench.The result of case analysis shows that the water drainage pipe trench surface horizontal displacement and the surface settlement after the construction does not exceed the maximum limit,which conforms to the accepted standard construction quality.The design technology can effectively ensure the construction quality,and has a good application prospect in the field of municipal road engineering.
