The invention provides a reinforcing construction method for a groove wall of an underground diaphragm wall of a lake-near complex geology subway station, and belongs to the technical field of underground foundation pit support structure construction of civil engineering. The lake-near complex geological subway station underground diaphragm wall groove wall reinforcing construction method comprises the following steps that a construction pile position is marked according to a control point of jet grouting pile construction measured by a total station; a mortar discharging groove is dug according to the position of the pile position mark point, and a mortar mixing system is erected; the geological drilling rig is moved to the designated pile position mark point position, and drilling is conducted on the pile position mark point position; the jet grouting pile machine is moved to the corresponding hole-forming pile position, a drill bit is aligned with the center of the hole-forming pile position, and jet grout
