Cement soil steel spiral composite pile and construction method thereof
The invention discloses a cement soil and steel spiral composite pile which comprises a cement soil mixing pile and a steel spiral pipe pile, the steel spiral pipe pile adopts a circular pipe body, the lower end of the steel spiral pipe pile is provided with a pointed cone, the upper end of the steel spiral pipe pile is provided with a connecting end plate, the outer wall of the steel spiral pipe pile is provided with a spiral blade, and the lower end of the cement soil mixing pile is inserted into a soft foundation bearing stratum. The steel spiral pipe pile serving as an inner core is vertically and completely or partially inserted into the cement-soil mixing pile, and the top end of the steel spiral pipe pile reaches the designed elevation; the invention further discloses a construction method of the cement soil steel spiral composite pile. The steel spiral pipe pile serving as an inner core is vertically and completely or partially inserted into the cement soil mixing pile to be compounded into the cement soil and steel spiral composite pile, so that the advantages of low cost of the cement soil mixing pile and bearing capacity increase of the steel spiral pipe pile are considered; the pile foundation structure is particularly suitable for projects with low requirements on the bearing capacity of the foundation under the soft foundation condition; the method has the advantages of low cost, simple process, short construction period, high corrosion resistance and proper bearing capacity.
本发明公开了一种水泥土钢螺旋复合桩，包括水泥土搅拌桩和钢螺旋管桩，所述钢螺旋管桩采用圆形管体，下端带有尖锥，上端带有连接端板，外壁上设置有螺旋叶片，所述水泥土搅拌桩的下端插入软弱地基持力层中，钢螺旋管桩作为内芯竖直地全部或部分插在所述水泥土搅拌桩中，钢螺旋管桩的顶端达到设计高程；还公开一种水泥土钢螺旋复合桩的施工方法。将钢螺旋管桩作为内芯竖直地全部或部分插在水泥土搅拌桩中复合成水泥土钢螺旋复合桩，兼顾了水泥土搅拌桩低成本和钢螺旋管桩增加承载能力的优点，特别适用于软弱地基条件下对于基础承载力要求不是特别高的项目作为桩基结构使用；具有成本低，工艺简单，施工周期短，抗腐蚀能力强，承载能力适当的优点。
