高压旋喷桩在地铁施工中的应用

摘要

With the acceleration of urbanization in China, metro industry has got rapid development. Taking Suzhou road station project of Hefei Metro for example, in order to ensure the safety of foundation pit and surrounding buildings, high pressure jet grouting technology is used for soil reinforcement. This paper elaborates the construction principle and construction technology of high pressure jet grouting pile, to provide some reference for similar engineering in the region.%随着我国城市化的不断加快，带来地铁行业的快速发展。本文以合肥市地铁宿州路站工程为例，为了保证基坑及周围建筑物的安全，采用高压旋喷对土层进行加固，阐述高压旋喷桩的施工原理、施工工艺，为本地区相似工程提供一些参考依据。
