The present disclosure belongs to the technical field of arch bridge structures, and particularly relates to a steel-concrete combined skewback structure and a construction method thereof. In the present disclosure, by arranging arch rib tubes, concrete sections in a main chord pipe, concrete blocks in a skewback, fixing steel tubes, a transverse diaphragm unit, and a vertical diaphragm unit, the steel-concrete combined skewback structure can achieve the following objectives that 1. the skewback structure can be fully connected with a bearing platform; and 2. the fixing steel tubes are fully filled with concrete. In addition, the present disclosure further provides the construction method of the above steel-concrete combined skewback structure. The construction method the skewback structure itself and its mounting manner both have sufficient structural stability.
A steel-concrete combined skewback structure, comprising arch rib tubes (11), concrete sections (12) in a main chord pipe, and concrete blocks (13) in a skewback, and further comprising a steel structure box unit (1) internally provided with the concrete blocks (13) in the skewback and used for allowing the arc rib tubes (11) to be inserted therein, fixing steel tubes (2) inserted into the steel structure box unit (1) and used for connecting a bearing platform (a), a transverse diaphragm unit (3) arranged in the steel structure box unit (1) and used for sleeving the fixing steel tubes (2), and a vertical diaphragm unit (4) arranged on the transverse diaphragm unit (3) and used for filling the fixing steel tubes (2) with concrete by sleeving the arch rib tubes (11).
