Tubular pile, tubular pile system and installation and manufacturing method thereof

LI JIN'AN

The invention provides a tubular pile, a tubular pile system and a mounting/manufacturing method thereof. The tubular pile includes an elongate tubular body having at least a first engagement element and a second engagement element extending longitudinally along an outer circumference thereof. The first engagement element is configured to slidably receive at least a portion of the second engagement element of an adjacent tubular pile in a cavity defined therein for interconnection. The second engagement element is configured to be slidably received at least partially in the cavity of the first engagement element of another adjacent tubular pile for interconnection. At least one of the first and second engagement elements has an expandable member fixedly connected to at least one face disposed within the cavity prior to interconnecting the elongated tubular pile with the or each adjacent tubular pile.

提供了一种管桩、管桩系统及其安装/制造方法。该管桩包括长形管本体，该长形管本体具有沿其外周纵向延伸的至少第一接合元件和第二接合元件。第一接合元件被配置成在其中限定的空腔中可滑动地接纳相邻管桩的第二接合元件的至少一部分，以进行互接。第二接合元件被配置成至少部分地可滑动地接纳在另一个相邻管桩的第一接合元件的空腔中，以进行互接。第一接合元件和第二接合元件中的至少一者具有可膨胀构件，在长形管桩与该相邻管桩或每个相邻管桩之间进行互接之前，该可膨胀构件固连至设置在所述空腔内的至少一个面。
