Steel pipe - shaped steel combination formula bracing underground structure

The utility model belongs to the technical field of architectural engineering technology and specifically relates to a steel pipe shaped steel combination formula bracing underground structure, its characterized in that: the supporter comprises steel pipe and shaped steel combination, shaped steel is arranged below the bottom surface of foundation ditch, the one end of steel pipe with shaped steelis connected, the other end with enclosure connects. The utility model has the advantages that: utilize the respective advantage of steel pipe and shaped steel well, be the steel pipe more than the foundation ditch bottom surface for the bracing has fine compressive capacity, has ensured stability, be shaped steel below the foundation ditch bottom surface, easily squeeze into than among the hardstratum, it is less to the influence of original state soil, ensured efficiency of construction and bracing bearing capacity, can in addition, combine engineering requirement, at the steel pipe set upthe slip casting structure
