树根桩(Root Piles)是一种小型的钻孔灌注桩,通常的直径是7.5～25.0cm。它是利用钻机边钻孔边清除孔内土直到设计深度,然后放入钢筋笼或者一根型钢,同时放入注浆管。注入水泥砂浆或者混凝土而成桩(亦可放碎石后,再注入水泥浆或者水泥砂浆,即用压浆法混凝土成桩)。施工时,根据需要,树根桩可以是垂直的,或是倾斜的;可以是单根的,或是成束的;可以是端承桩,亦可以是摩擦桩。 Root Piles is a small bored pile, typically 7.5 to 25.0 cm in diameter. It is the use of drilling machines while drilling holes to remove the soil until the design depth, and then into the steel cage or a steel, while the injection pipe. Inject cement mortar or concrete into piles (or grind stones, then inject cement slurry or cement mortar, that is, use cement mortar to form piles). During construction, the root piles can be vertical or inclined as required; they can be single or bundled; they can be end-bearing piles or friction piles.
