Prestressed concrete rectangular pile and construction method thereof
The invention relates to a prestressed concrete rectangular pile and a construction method thereof. The prestressed concrete rectangular pile comprises a concrete pile body (1) with a rectangular cross section, the concrete pile body (1) is of a hollow thin-wall structure, a hollow hole (2) is formed in the middle of the concrete pile body (1), and prestressed steel strands (3), stirrups (4) and grouting holes (5) are arranged in the concrete pile body (1); an upper flange plate (7) is arranged at the top of the concrete pile body (1), and a pile shoe (6) or a lower flange plate (8) is arranged at the bottom of the concrete pile body (1). The cross section of the prestressed concrete rectangular pile is in a hollow rectangle shape, and the horizontal load bearing capacity of a rectangular section form is better than that of a circular section form, so that the bending rigidity of a support pile is improved, the material consumption can be saved, and the engineering cost is saved.
本发明涉及一种预应力混凝土矩形桩及其施工方法，预应力混凝土矩形桩包括横截面为矩形的混凝土桩身(1)，所述混凝土桩身(1)为空心薄壁结构，所述的混凝土桩身(1)中部为中空孔洞(2)，所述混凝土桩身(1)内部设有预应力钢绞线(3)、箍筋(4)和注浆孔洞(5)，所述混凝土桩身(1)顶部设有上法兰盘(7)，所述混凝土桩身(1)底部设有桩靴(6)或下法兰盘(8)。本发明预应力混凝土矩形桩的横截面为空心矩形，矩形截面形式承受水平荷载的能力优于圆形截面形式，因此既提高了支护桩的抗弯刚度，又能节省材料用量，节约工程造价。
