The invention discloses a laser-monitoring static-pressure hole guiding and pile sinking construction method for a super-thick pebbly sand layer, and relates to the technical field of pebbly sand layer construction. The laser-monitoring static-pressure hole guiding and pile sinking construction method for the super-thick pebbly sand layer comprises the steps of enabling a pile machine to be in place; carrying out pile sinking; contacting the pebbly sand layer; cleaning mud and mortar, and then guiding a hole; starting laser-monitoring construction; enabling a drilling machine to be in place; positioning and measuring; carrying out high pressure jet grouting and drilling; positioning a hole guiding pile position; carrying out lift drilling; carrying out static-pressure pile pipe hole guiding; and carrying out static-pressure pile sinking. According to the step of starting laser-monitoring construction, the perpendicularity of a pile body is directly decided by the perpendicularity of hole guiding of the construction method, and the perpendicularity of hole guiding of the construction method plays an important role in pile forming quality, so that in the hole guiding process, two photoelectric laser plummet apparatuses form a 90-degree angle and align at a hole guiding drill rod axis so as to monitor the perpendicularity in X and Y directions. The laser-monitoring static-pressurehole guiding and pile sinking construction method for the super-thick pebbly sand layer solves the problems of the restriction on multiple factors such as power consumption and inconvenience in moving a machine, and the difficulty of a special pebbly sand layer pile sinking technology brought by the severe influence on foundation treatment.
