带帽预应力管桩在桥头深厚软土路基施工中的应用

Application of Hooded Prestressed Pipe Pile at Bridgehead Deep Soft Soil Roadbed Construction

带帽预应力管桩具有单桩承载力高,施工进度快,噪声小,污染少,穿越土层能力强,现场施工方便,质量好控制,桩身耗材较低,单桩造价低等特点。用于桥头深厚软基处理时整体造价远低于桥梁工程,施工完成的桥头路基工后沉降小,建议桥头深厚软基处理大力提倡采用带帽预应力管桩。

Hooded prestressed pipe pile has some advantages such as high construction speed,little noise,no pollution,strong crossing soil ability,easy construction and quality control,low amount of materials and low single pile cost.When bridgehead deep soft soil roadbed is strengthened with hooded prestressed pipe pile,the whole cost is far lower than bridge engineering.After construction,settlement of bridgehead roadbed is very small.This kind of pile should be applied widely in bridgehead deep soft soil roadbed treatment.
