Drainage stiffening core composite pile based on geopolymer grouting and construction method thereof
The invention relates to a drainage stiffening core composite pile based on geopolymer grouting and a construction method thereof. The composite pile comprises a middle core pile and a peripheral pile, the middle core pile is wrapped with the peripheral pile, the middle core pile is a geopolymer material slurry-solidified gravel pile, and the peripheral pile is a sand pile capable of draining water. The geopolymer material slurry-solidified gravel pile is in occlusion contact with the sand pile to form the drainage stiffening core composite pile. The composite pile technology and the geopolymer material technology are combined, the dual functions of foundation reinforcement and drainage are achieved through the solidification effect of the geopolymer material and the drainage effect of the sand pile, and the bearing capacity of a soft soil foundation is greatly improved. The construction process is simple, operability is high, the drainage stiffening core composite pile obtained through construction is good in integrity, high in bearing capacity, high in drainage speed and remarkable in soft soil foundation reinforcing effect, geopolymer slurry is prepared from industrial waste residues, and the drainage stiffening core composite pile is environmentally friendly, low in carbon and high in economic benefit.
本发明涉及一种基于地聚合物注浆的排水劲芯复合桩及其施工方法，包括中间芯桩和外围桩，外围桩包裹中间芯桩，中间芯桩为地聚合物材料浆固碎石桩，外围桩为可排水的砂桩，地聚合物材料浆固碎石桩与砂桩咬合接触以组成排水劲芯复合桩。本发明将复合桩技术与地聚合物材料技术结合起来，利用地聚合物材料的固化效应和砂桩的排水效应，实现地基加固与排水的双重作用，大幅度提高了软土地基的承载力；本发明施工工艺简单，可操作性强，施工得到的排水劲芯复合桩不仅整体性好、承载力高、排水速度快，加固软土地基效果显著，而且利用工业废渣制备地聚合物浆液，绿色低碳、经济效益高。
