桩基础是基础处理中最常见的深基础处理方式之一,在我国有悠久历史,积累了许多丰富的施工经验。按桩的施工方法,可分成灌注桩和预制桩。预制钢筋混凝土三角桩是预制桩的新发展,是桩基础中的特殊桩。它的特点:一是桩的横断面是三角形,两端是平头;二是桩体是中空的,桩孔截面是多样化的。下面从几方面与预制钢筋混凝土方形桩、圆形桩(桩的横断面)作一下比较,它兼具了预制钢筋混凝土桩和 Pile foundation is one of the most common deep foundation treatment in foundation treatment. It has a long history in our country and has accumulated rich experience in construction. Piles of construction methods, can be divided into bored piles and precast piles. Precast reinforced concrete triangular piles are the new development of precast piles and are special piles in pile foundation. Its features: First, the cross-section of the pile is triangular, both ends are flat head; Second, the pile is hollow, pile hole cross-section is diverse. Here are some aspects of prefabricated reinforced concrete square pile, circular pile (pile cross-section) for a comparison, which combines both precast reinforced concrete piles and
