Application of Bag Pile Construction Technology in Corrosion Prevention for Bridge and Culvert Foundation in Saline Soil Area

This paper aims at bridge foundation corrosion of highway in saline soil area.Combining with the construction project of Qarhan Salt Lake-Gomud Highway of National Road 215,the genesis of saline soil and the mechanism of it corroding structures were analyzed so as to study the feasibility of bag piles as resolution of such corrosion and generalize the bag material properties,construction process,quality control and other related key points.The result of engineering practice shows that bag piles could solve anticorrosion of structures,such as bridge and culvert,in saline soil area effectively.
