Novel variable-cross-section splicable steel pipe screw pile
The invention relates to the technical field of steel pipe screw piles, and discloses a novel variable-cross-section splicable steel pipe screw pile which comprises a flange plate. The pile body is of a hollow cylindrical structure, and the top of the pile body is connected with the bottom of the flange plate; the multiple first spiral blades are arranged on the outer side wall of the pile body in a surrounding mode, and the diameter of the first spiral blade away from the flange plate is smaller than that of the first spiral blade close to the flange plate; the top of the pile head is connected with the bottom of the pile body, and the pile head is conical; and the second spiral blade is arranged on the outer side wall of the pile head in a surrounding mode, the diameter of the second spiral blade is gradually increased from the bottom of the pile head to the top of the pile head, and the diameter of the second spiral blade is smaller than that of the first spiral blade. The novel variable-cross-section splicable steel pipe screw pile can be repeatedly used, is simple in structure, convenient to construct, high in environment adaptability and high in bearing capacity, can be recycled, and can be spliced on site according to actual needs.
本发明涉及钢管螺旋桩技术领域，公开了一种变截面可拼接新型钢管螺旋桩，包括：法兰盘；桩体，为中空筒状结构，桩体的顶部与法兰盘的底部连接；第一螺旋叶片，设置有若干个，若干第一螺旋叶片环绕设置在桩体的外侧壁上，且远离法兰盘的第一螺旋叶片的直径小于靠近法兰盘的第一螺旋叶片的直径；桩头，顶部与桩体的底部连接，桩头设置为锥状；第二螺旋叶片，环绕设置在桩头的外侧壁上，第二螺旋叶片的直径由桩头底部到桩头顶部逐渐增加，且第二螺旋叶片的直径小于第一螺旋叶片的直径。本发明的变截面可拼接新型钢管螺旋桩可重复使用，结构简单，施工便捷，适应环境能力强，承载能力强，且可做到回收再利用，能够按实际所需进行现场拼接。
