摘要： A covering is applied onto the outer surface of a pile including a steel pipe or the like to surround a predetermined length thereof so as to reduce a frost heaving force or negative friction acting on the pile in a frigid area. The covering is closely adhered by an adhesion layer the like to the pile over a given length thereof. This given length is between 0.5 and 5 m. The covering member includes a smooth-surfaced plastic covering or elastic covering. A rugged surface covering may be provided below the smooth surfaced covering.

摘要翻译： 将覆盖物施加到包括钢管等的桩的外表面上以围绕其预定长度，以便减少在寒冷地区中作用在桩上的霜冻力或负摩擦力。 覆盖层在其给定长度上通过粘合层紧密地粘附到桩上。 该给定长度在0.5和5米之间。 覆盖构件包括光滑表面的塑料覆盖物或弹性覆盖物。 可以在光滑的表面覆盖物的下方提供粗糙的表面覆盖物。
