Ultra-wide partition-plate-free steel box girder segment height difference adjusting and installing method

The invention belongs to the technical field of bridge construction, and particularly relates to an ultra-wide partition-plate-free steel box girder segment height difference adjusting and mounting method which comprises the following steps: step 1, overall positioning: a bridge is integrally positioned, and a datum point required by a monitoring instruction is used as a control point for overall positioning of a girder segment; according to the ultra-wide partition-free steel box girder segment height difference adjusting and installing method, through the arrangement of the first step to the ninth step, rapid, efficient and accurate height difference adjusting and installing of the ultra-wide partition-free steel box girder segment are achieved, and the method has the beneficial effects that operation is easy, a large number of heavy equipment does not need to be used, the construction efficiency is high, and the construction cost is low; therefore, the problems that local height difference exists between a
