Threaded pile for soft foundation treatment and construction method thereof
The invention discloses a threaded pile for soft foundation treatment and a construction method thereof. The threaded pile comprises a pile body, wherein a grouting opening is formed in the upper end of the pile body, and a spiral groove which communicates with the grouting opening, is wound around the pile body in the circumferential direction and extends downwards is formed in the outer wall of the pile body. The construction method comprises the steps that the threaded pile is piled, and then grouting is carried out in the spiral groove. According to the threaded pile for soft foundation treatment and the construction method thereof, a traditional piling mode is adopted, grouting is carried out by pulling out a grouting pipe or directly after knotting, the grouting opening and the spiral groove of the spiral pile body can be filled through later grouting, the pile body can be meshed with surrounding soil, a vein-shaped and net-shaped system can be formed between the surrounding soil and the pile body, the soil around the pile body can be reinforced, the friction force and the contact area between the pile body and the soil can be increased, and therefore a soft foundation can be efficiently treated, the whole construction process is simple, and cost is saved.
本发明公开了一种用于软基处理的螺纹桩及其施工方法，所述螺纹桩包括桩身，所述桩身的上端设有注浆口，所述桩身的外壁上设有与所述注浆口连通、绕桩身周向缠绕并向下延伸的螺旋凹槽。所述施工方法包括对螺纹桩进行打桩，然后向螺旋凹槽内进行注浆的过程。本发明采用传统的打桩方式，在施打结束后采用抽出注浆管注浆或直接注浆的方式进行注浆，采用后期注浆不仅可以填充螺旋桩身的注浆口和螺旋凹槽，使桩体和周围的土体咬合，还可以使得周边土体与桩身之间形成脉状和网状体系，不仅可以加固桩身周围的土体，还可以加大桩身和土体之间的摩擦力和接触面积，以此高效的对软土地基进行处理，整个施工过程简单、节约成本。
