jet grouting pile

Brief introduction of engineering case for treatment of bridge and culvert soft foundation with gravel pile and of tunnel soft foundation with high-pressure jet grouting pile.

简单介绍了采用碎石桩进行桥涵软基处理，采用高压旋喷桩进行隧道软基处理的工程实例。

Several construction technologies are applied including diaphragm wall as retaining structure, jet grouting pile, grouting and artesian aquifer dewatering for soft ground stabilization and steel support, reinforced concrete support, steel framework and fabricated steel bracket for supporting system.

选用旋喷桩、注浆加固、承压降水井点等方法进行软土地基加固，选用钢支撑、钢筋混凝土支撑、钢框架及装配式钢牛腿等组合支撑体系；

After the loess tunnel after the foundation treatment has been open to traffic, and is running well, explains the high pressure jet grouting pile foundation reinforced loess tunnel obvious effect, of great economic benefits and social benefits, is worth popularizing widely application.

经过地基处理后的黄土隧道目前已经通车，并运行良好，说明了高压旋喷桩加固黄土隧道地基效果明显，具有很大的经济效益和社会效益，值得广泛推广应用。
