Miniature steel pipe pile tower foundation and construction method thereof
The miniature steel pipe pile tower foundation comprises a miniature steel pipe arranged in a pile hole, the miniature steel pipe is filled with cement mortar, the top of the miniature steel pipe is connected with a ground bearing platform, and a plurality of overflow ports are symmetrically formed in the bottom of the miniature steel pipe. Extrusion mechanisms for forming pile end expanded heads are hinged to the interiors of the multiple overflow ports; and the bottom of the prestress applying mechanism is in transmission connection with the multiple extrusion mechanisms, and the top of the prestress applying mechanism is fixedly connected with the ground bearing platform. The horizontal bearing capacity is improved through the prestress applying mechanism, the cement mortar integrally forms the expansion head through extrusion of the extrusion mechanism, the uplift bearing capacity is improved, the comprehensive performance of the miniature steel pipe pile tower foundation is improved, and the beneficial effects that the construction efficiency is improved, the labor intensity is reduced, and the operation risk is reduced are achieved.
本发明公开了一种微型钢管桩杆塔基础及其施工方法，包括设置在桩孔内的微型钢管，所述微型钢管内填充有水泥砂浆，所述微型钢管顶部连接有地面承台，所述微型钢管的底部对称的开设有多个溢流口，且多个所述溢流口内均铰接有用于形成桩端扩大头的挤压机构；预应力施加机构，其底部与多个所述挤压机构传动连接，且所述预应力施加机构的顶部与所述地面承台固定连接。本发明，通过预应力施加机构提高水平承载力，并通过挤压机构的挤压，使得水泥砂浆一体形成扩大头，提高抗拔承载力，实现了微型钢管桩杆塔基础综合性能的提升，具有提升施工效率、减少劳动强度、降低作业风险的有益效果。
