Electrolytic gravel pile composite foundation for liquefiable foundation and construction method
The invention discloses an electrolytic gravel pile composite foundation for a liquefiable foundation and a construction method. The electrolytic gravel pile composite foundation comprises a pile, the pile comprises a pile hole, the lower portion of the pile hole is an electrolytic gravel pile section, the upper portion of the pile hole is a slurry consolidated gravel pile section, a filtering layer is arranged between the electrolytic gravel pile section and the slurry consolidated gravel pile section, a grouting pipe and a hole washing pipe are arranged in the pile hole. The grouting pipe and the hole washing pipe are both connected with a power source, the electrolytic gravel pile section is filled with second gravel aggregate, the slurry consolidated gravel pile section is filled with first gravel aggregate, and cement mortar is injected through the grouting pipe. According to the electrolytic gravel pile composite foundation for the liquefiable foundation and the construction method, pore water in the liquefiable foundation is electrolyzed to generate gas, so that the purposes of reducing the saturation of the foundation and improving the anti-liquefaction strength are achieved; a tubular EKG electrode is adopted as the grouting pipe and the hole washing pipe, and the novel drainage pipe electrode combines the corresponding advantages of a plastic drainage pipe and an electrolyzable electrode material, so that the tubular EKG electrode can have drainage and electrolysis functions at the same time.
本发明公开了一种用于可液化地基的电解碎石桩复合地基及施工方法，包括桩，所述的桩包括桩孔，桩孔下部为电解碎石桩段，上部为浆固碎石桩段，所述的电解碎石桩段和浆固碎石桩段之间设有过滤层，所述的桩孔内设有注浆管和洗孔管，所述的注浆管和洗孔管均与电源连接，所述的电解碎石桩段填充有第二碎石骨料，所述的浆固碎石桩段填充有第一碎石骨料，并通过注浆管注入水泥砂浆。本发明通过电解可液化地基中的孔隙水生成气体，达到减小地基饱和度并提高抗液化强度的目的；采用管状EKG电极作为注浆管和洗孔管，这种新型排水管电极结合了塑料排水管和可电解电极材料的相应优势，使得管状EKG电极能够同时具备排水和电解作用。
