Forward rotation expansion threaded pile, construction method thereof and spiral expansion drilling tool
The invention discloses a forward rotation expanded body threaded pile, a construction method thereof and a spiral expanded body drilling tool. The forward rotation expanded body threaded pile, the construction method of the forward rotation expanded body threaded pile and the spiral expanded body drilling tool used in the construction method of the forward rotation expanded body threaded pile are included. The construction method of the forward rotation expansion body threaded pile comprises a pile body construction method and a dense expansion body construction method. The forward rotation expansion body threaded pile comprises a pile body and a dense expansion body. The spiral body expanding drilling tool comprises a drilling tool core rod, a spiral blade and extruding and expanding teeth. The construction method has the beneficial effects that the forward rotation expanded body threaded pile with the dense expanded body is formed by utilizing the spiral expanded body drilling tool and the forward rotation expanded body threaded pile construction method, the construction process is simple and reliable, the bearing capacity of the pile side and the pile end is greatly improved compared with other various rotary drilling cast-in-place piles, and the application prospect is wide.
本发明公开了基于一种正旋扩体螺纹桩及其施工方法和螺旋扩体钻具,包括一种正旋扩体螺纹桩、一种正旋螺纹扩体螺纹桩的施工方法和一种正旋扩体螺纹桩施工方法使用的螺旋扩体钻具;其中,正旋扩体螺纹桩的施工方法包括桩身施工方法和密实扩大体施工方法;正旋扩体螺纹桩包括桩身和密实扩大体;螺旋扩体钻具包括钻具芯杆、螺旋叶片和挤扩齿。本发明的有益效果是:利用螺旋扩体钻具及正旋扩体螺纹桩施工方法形成带有密实扩大体正旋扩体螺纹桩,施工工艺简单可靠,且桩侧及桩端承载力相比其它各式旋转钻进的灌注桩都有较大的提升,应用前景广泛。
