穿越河流管段植桩稳固施工技术

Construction Technology of Planting Column to Firm Pipeline Section Crossing River

在长输管道河流穿越工程中,因各种原因造成穿越管段埋深达不到安全位置,为此采取植桩稳固管道的辅助措施。文中叙述了植桩稳固管道施工的全过程、参数计算及施工方法。经实践论证,这种方法具有节省人力、物力、时间的优点,可供特殊工程借鉴。

Because the crossing section of pipeline in engineering of long transpoetation can＇t be buried so deep as to rearch ist safety depth by some reasons, an auxiliary measure by planting column to firm the pipeline crossing river was taken. This paper describes the whole process of plating column, to firm pipeline parameters calculation and construction method. After revified by practice, this method has advantages of saving labour work, materials and time. It provides a reference for special engineering.
