摘要
本文在介绍膜袋注浆桩及其加固机理的基础上,结合以往工程经验,将膜袋注浆桩应用于已通车道路桥头软基处理工程中,选用施工工艺不会影响交通,不破坏既有道路。结果表明:膜袋注浆桩对已通车道路桥头软基处理加固效果明显,注浆成桩后可有效减缓桥头路基的沉降速率,有效防止桥头跳车。
On the basis of the detailed introduction to Reinforcement mechanism of bag grouting pile.Combined with previous work experience,The Bag Grouting Pile has been applied to the opening of the bag- grouting pile road Soft Foundation Treatment Project,the selection of the construction process will not affect traffic,does not destroy the existing road.The results showed that： bag grouting pile of road has been opened to traffic Soft Foundation Treatment reinforcing effect is obvious,after grouting pile can effectively reduce the rate of subsidence bridge roadbed,effectively preventing Bridgehead Jump.
