Polypropylene fiber reinforced cement-soil mixing pile and construction process thereof
The invention discloses a polypropylene fiber reinforced cement soil mixing pile and a construction technology thereof. The mixing pile is composed of raw material soil, ordinary Portland cement, polypropylene fibers, water and a high-performance water reducing agent. The content of each component is as follows: 89% of a soil sample, 7% of ordinary Portland cement, 0.4% of polypropylene fiber, 3.5% of water and 0.1% of a high-performance water reducing agent. The novel mixing pile construction technology comprises the steps that firstly, polypropylene fibers and a soil sample are evenly mixed and stirred; then preparing polypropylene fiber cement mixed slurry; then a motor is started, mixed slurry is extruded out of a slurry spraying opening through a mortar pump, and the drill rod is lifted to the designed elevation while slurry spraying stirring is conducted; and finally, sinking, lifting, guniting and stirring are repeated, and the polypropylene fiber reinforced cement soil stirring pile is formed. Compared with a traditional mixing pile, the novel reinforced mixing pile has high tensile and compressive strength and shear strength, the anti-seepage, anti-deformation and early strength capacity of cement soil is improved, and high economic benefits, environmental benefits and practical value are achieved.
本申请公开了一种聚丙烯纤维加筋水泥土搅拌桩及其施工工艺，该搅拌桩由原料土、普通硅酸盐水泥、聚丙烯纤维、水及高性能减水剂组成；各组分含量为：土样占比89％、普通硅酸盐水泥占比7％、聚丙烯纤维占比0.4％、水占比3.5％、高性能减水剂占比0.1％。所述新型搅拌桩施工工艺包括：首先均匀混拌聚丙烯纤维与土样；然后配置聚丙烯纤维水泥混合浆液；再启动电机并利用灰浆泵将混合浆液挤出喷浆口，边喷浆搅拌边提升钻杆至设计标高；最后重复下沉提升、喷浆搅拌，形成聚丙烯纤维加筋水泥土搅拌桩。所述新型加筋搅拌桩较传统搅拌桩具有较强的抗拉压强度、抗剪强度，提高水泥土防渗抗变形及早强能力，具有较高的经济效益、环境效益及实用价值。
