老旧城区复杂路段管槽土方开挖支护方法研究

Research on Excavation and Support Methods for Pipe Trench Earthwork in Complex Road Sections of the Old Urban Area

老旧城区复杂路段多,加上旧城改造施工项目的增加,使得复杂路段的管槽土方开挖支护施工技术应用难度加大。为了保证老旧城区复杂路段整个排水系统运行顺畅,主干道的设计中应加入排水设计,确保土方开挖排水通畅,因此路段管槽土方开挖支护尤为关键。在老旧城区复杂路段管槽土方开挖及支护施工作业的过程中,应明确具体的施工流程,细化施工技术内容,梳理出施工中的重难点并找出施工解决措施。文章结合具体案例,分析了管槽土方开挖及支护施工技术,旨在以此为老旧城区复杂路段管槽土方开挖施工作业质量的提升提供方法参考。

There are many complex road sections in the old urban area and the number of construction projects in old urban area reconstruction increases,making the application of the pipe trench earthwork excavation and support construction technology in complex road sections more difficult.In order to ensure the smooth operation of the entire drainage system in complex road sections of the old urban area,the drainage design should be added to the design of the main road to ensure the smooth drainage during earthwork excavation,so the pipe trench earthwork excavation and support in road sections is particularly critical.In the process of pipe trench earthwork excavation and support construction in complex road sections of the old urban area,specific construction processes should be clarified,construction technology content should be refined,key and difficult points in construction should be identified,and construction solutions should be found out.Combined with specific cases,this paper analyzes the construction technology of pipe trench earthwork excavation and support,aiming to provide a method reference for improving the quality of pipe trench earthwork excavation construction in complex road sections of the old urban area.
