The invention relates to the field of building jacking, in particular to a building jacking method and a cross-core type self-occlusion jack. The method comprises the following steps that a foundation of a building to be jacked is dug out; anchor rods and tray beams are arranged along the two sides of the foundation wall, and a bearing beam is arranged between the tray beams. The anchor rod is sleeved with a cross-core type self-occlusion jack with a cylinder body part and a telescopic part; the lifting steel frame is connected with the tray beam, and the cross-core type self-occlusion jack is arranged between the tray beam and the lifting steel frame; when the cylinder body part is engaged with the anchor rod, the telescopic part can move along the anchor rod, and when the telescopic part is engaged with the anchor rod, the cylinder body part can move along the anchor rod. Hydraulic occlusion assemblies are arranged at the bottom of a cylinder body part and the top of a telescopic part in the cross-core type self-occlusion jack, each hydraulic occlusion assembly comprises an occlusion clamping jaw and a clamping jaw driving unit, and the clamping jaw driving units can drive the occlusion clamping jaws to be close to or away from the engagement tooth structures. According to the construction method, basement construction can be conveniently conducted on an existing building in a narrow space.
