Construction Technology of Large Diameter Cast-in-place Pile Foundation Reinforcement of Municipal Bridge
The acceleration of urbanization process,the construction of urban infrastructure put forward higher requirements.As an important part of municipal engineering,the construction quality of bridge directly affects the construction quality of municipal engineering project.However,in the actual construction process,due to geological conditions,construction environment,construction technology and other factors,pile foundation construction will inevitably encounter some problems and risks,affect the smooth implementation of the project.In this paper,based on a practical case,through the analysis of high-pressure grouting method,small diameter steel pipe pile reinforcement method and belled pile reinforcement method of three schemes of construction and results,finally,the small diameter steel pipe pile reinforcement method has better durability and reliability.
