Helical immersed tube cast-in-place pile with wings and construction method
The invention provides a winged spiral tube-sinking cast-in-place pile and a construction method. The winged spiral tube-sinking cast-in-place pile comprises at least one section of sleeve, the sleeve is sleeved with a spiral wing, the sleeve and the spiral wing form penetrating connection avoiding assembly through an axial inserting connection structure, the sleeve and the spiral wing form disassembly and assembly matching through a first rotary clamping and embedding structure, and the bottom end of the lowest sleeve is sleeved with a pile tip. The casing pipe and the pile tip are detachably matched through a second rotary clamping and embedding structure, a reinforcement cage is arranged in the casing pipe, concrete is poured into the pile tip and the casing pipe, the reinforcement cage is coated with the concrete, and the concrete is solidified to bond the pile tip and the spiral wing. The operation mode that the whole pile is drilled into the foundation and the whole pipe is pulled out is facilitated, the operation difficulty is simplified, and the working efficiency is remarkably improved. The spiral pile structure is combined with the construction method of the tube-sinking cast-in-place pile, and the spiral blade is combined to the concrete cast-in-place pile by designing the spiral wing and the pile tip of a special structure, so that the bearing capacity is greatly improved, the construction speed is high, the construction noise is low, and the types of the spiral piles are expanded.
本发明提供了一种带翼螺旋沉管灌注桩及施工方法，包括至少一节套管，套管上套接螺旋翼，套管与螺旋翼之间通过轴向插接结构形成穿接避位装配，套管与螺旋翼之间通过旋转卡嵌结构一形成拆装配合，最低位的套管底端套接桩尖，套管与桩尖之间通过旋转卡嵌结构二形成拆装配合，套管内置入钢筋笼，桩尖与套管内灌注混凝土，混凝土包覆钢筋笼，混凝土凝固粘接桩尖及螺旋翼。本发明便于整桩钻入地基，整管拔出的作业方式，简化操作难度，显著提升工作效率。本发明将螺旋桩结构与沉管灌注桩的施工方法相结合，通过设计特殊结构的螺旋翼和桩尖，将螺旋叶片结合至混凝土灌注桩上，以使承载力大大提高，施工速度快，施工噪音小，并扩展了螺旋桩的类型。
