Research on the Application of Parallel Pipe Jacking Construction in Urban Comprehensive Pipe Gallery
Based on a new urban comprehensive pipe gallery project in Nanjing,this paper introduces the design points of pipe gallery constructed by parallel pipe jacking method,and analyzes the influence of parallel pipe jacking method on the surrounding environment by finite element numerical simulation method.The results show that different pipe jacking sequences will affect the deformation degree of soil layer.Therefore,a reasonable selection of the jacking sequence for multi-line pipe jacking should be made,and control measures for the entire process of parallel pipe jacking construction should be proposed based on the analysis results,in order to achieve the purpose of adapting to local conditions and reducing the impact on structures and surrounding environment,which can provide reference for similar projects.
