高压旋喷钢管桩在桥梁桩基加固中的应用研究

Research on the application of high pressure jet grouting steel pipe pile in bridge pile foundation reinforcement

高压旋喷钢管桩施工技术,能够有效的提升地基承载力,改变地基受力性质,是桥梁桩基加固中常用的技术形式。近年来,我国基础设施建设不断深入,桥梁工程的数量与规模也不断扩大,本文就以某座大桥工程桩基加固实例,探讨高压旋喷钢管桩在桥梁桩基加固中的运用,希望能够对相关工程施工以启发。

High pressure rotary spray steel pipe pile construction technology, can effectively improve the bearing capacity of the foundation, to change the strength of the foundation, is the common technical form in bridge pile foundation reinforcement. In recent years, the infrastructure construction of our country is gradually deepening, bridge engineering quantity and the scale is expanding constantly, this paper takes a bridge pile foundation reinforcement as an example, discuss the application of high pressure jet grouting steel pipe pile in the reinforcement of bridge pile foundation, and hope to bring some inspiration to the relevant engineering construction.
