Expansion pile and construction method thereof
The invention provides an expansion pile and a construction method thereof.The expansion pile comprises a first elastic restraining piece and an expansion column, a first column cavity is formed in the first elastic restraining piece, and water permeable holes communicating with the first column cavity are formed in the peripheral wall of the first elastic restraining piece; the expansion column is located in the first column cavity and extends in the axial direction of the first column cavity, the expansion pile further comprises a supporting piece, the supporting piece is located in the first column cavity and is adjacent to the inner circumferential wall of the first elastic restraining piece, and the supporting piece spirally extends in the axial direction of the first column cavity and is wound around the periphery of the expansion column; in the radial direction of the first column cavity, the area of the cross section of the expansion column is between 1/2 and 2/3 of the area of the cross section of the first column cavity; the expansion column comprises a first expansion material and a second elastic restraining piece wrapping the periphery of the first expansion material, and the second elastic restraining piece is permeable. The expansion pile is low in construction cost, good in structural strength, simple in construction technology and convenient to operate, and the construction period is effectively shortened.
本发明提供一种膨胀桩及其施工方法，该膨胀桩包括第一弹性约束件和膨胀柱，第一弹性约束件的内部开设有第一柱体腔，第一弹性约束件的周壁开设有与第一柱体腔相连通的透水孔，膨胀柱位于第一柱体腔内并在第一柱体腔的轴向上延伸，膨胀桩还包括支撑件，支撑件位于第一柱体腔内并邻接第一弹性约束件的内周壁设置，且支撑件在第一柱体腔的轴向上螺旋延伸缠绕在膨胀柱的外周；在第一柱体腔的径向上，膨胀柱的横截面的面积为第一柱体腔的横截面的面积的1/2至2/3之间；膨胀柱包括第一膨胀材料以及包裹在第一膨胀材料外周的第二弹性约束件，第二弹性约束件可透水。本发明的膨胀桩的施工成本低，结构强度较好，施工工艺简单，方便操作，有效缩短施工工期。
